Background Melphalan flufenamide (melflufen), an alkylating peptide-drug conjugate, plus dexamethasone showed clinical activity and manageable safety in the phase 2 HORIZON study. We aimed to determine whether melflufen plus dexamethasone would provide a progression-free survival benefit compared with pomalidomide plus dexamethasone in patients with previously treated multiple myeloma. Methods In this randomised, open-label, head-to-head, phase 3 study (OCEAN), adult patients (aged ≥18 years) were recruited from 108 university hospitals, specialist hospitals, and community-based centres in 21 countries across Europe, North America, and Asia. Eligible patients had an ECOG performance status of 0–2; must have had relapsed or refractory multiple myeloma, refractory to lenalidomide (within 18 months of randomisation) and to the last line of therapy; and have received two to four previous lines of therapy (including lenalidomide and a proteasome inhibitor). Patients were randomly assigned (1:1), stratified by age, number of previous lines of therapy, and International Staging System score, to either 28-day cycles of melflufen and dexamethasone (melflufen group) or pomalidomide and dexamethasone (pomalidomide group). All patients received dexamethasone 40 mg orally on days 1, 8, 15, and 22 of each cycle. In the melflufen group, patients received melflufen 40 mg intravenously over 30 min on day 1 of each cycle and in the pomalidomide group, patients received pomalidomide 4 mg orally daily on days 1 to 21 of each cycle. The primary endpoint was progression-free survival assessed by an independent review committee in the intention-to-treat (ITT) population. Safety was assessed in patients who received at least one dose of study medication. This study is registered with ClinicalTrials.gov, NCT03151811, and is ongoing. Findings Between June 12, 2017, and Sept 3, 2020, 246 patients were randomly assigned to the melflufen group (median age 68 years [IQR 60–72]; 107 [43%] were female) and 249 to the pomalidomide group (median age 68 years [IQR 61–72]; 109 [44%] were female). 474 patients received at least one dose of study drug (melflufen group n=228; pomalidomide group n=246; safety population). Data cutoff was Feb 3, 2021. Median progression-free survival was 6·8 months (95% CI 5·0–8·5; 165 [67%] of 246 patients had an event) in the melflufen group and 4·9 months (4·2–5·7; 190 [76%] of 249 patients had an event) in the pomalidomide group (hazard ratio [HR] 0·79, [95% CI 0·64–0·98]; p=0·032), at a median follow-up of 15·5 months (IQR 9·4–22·8) in the melflufen group and 16·3 months (10·1–23·2) in the pomalidomide group. Median overall survival was 19·8 months (95% CI 15·1–25·6) at a median follow-up of 19·8 months (IQR 12·0–25·0) in the melflufen group and 25·0 months (95% CI 18·1–31·9) in the pomalidomide group at a median follow-up of 18·6 months (IQR 11·8–23·7; HR 1·10 [95% CI 0·85–1·44]; p=0·47). The most common grade 3 or 4 treatment-emergent adverse events were thrombocytopenia (143 [63%] of 228 in the melflufen group vs 26 [11%] of 246 in the pomalidomide group), neutropenia (123 [54%] vs 102 [41%]), and anaemia (97 [43%] vs 44 [18%]). Serious treatment-emergent adverse events occurred in 95 (42%) patients in the melflufen group and 113 (46%) in the pomalidomide group, the most common of which were pneumonia (13 [6%] vs 21 [9%]), COVID-19 pneumonia (11 [5%] vs nine [4%]), and thrombocytopenia (nine [4%] vs three [1%]). 27 [12%] patients in the melflufen group and 32 [13%] in the pomalidomide group had fatal treatment-emergent adverse events. Fatal treatment-emergent adverse events were considered possibly treatment related in two patients in the melflufen group (one with acute myeloid leukaemia, one with pancytopenia and acute cardiac failure) and four patients in the pomalidomide group (two patients with pneumonia, one with myelodysplastic syndromes, one with COVID-19 pneumonia). Interpretation Melflufen plus dexamethasone showed superior progression-free survival than pomalidomide plus dexamethasone in patients with relapsed or refractory multiple myeloma., Oncopeptides AB

BACKGROUND: Janus kinase (JAK) inhibitors approved for myelofibrosis provide spleen and symptom improvements but do not meaningfully improve anaemia. Momelotinib, a first-in-class inhibitor of activin A receptor type 1 as well as JAK1 and JAK2, has shown symptom, spleen, and anaemia benefits in myelofibrosis. We aimed to confirm the differentiated clinical benefits of momelotinib versus the active comparator danazol in JAK-inhibitor-exposed, symptomatic patients with anaemia and intermediate-risk or high-risk myelofibrosis.METHODS: MOMENTUM is an international, double-blind, randomised, controlled, phase 3 study that enrolled patients at 107 sites across 21 countries worldwide. Eligible patients were 18 years or older with a confirmed diagnosis of primary myelofibrosis or post-polycythaemia vera or post-essential thrombocythaemia myelofibrosis. Patients were randomly assigned (2:1) to receive momelotinib (200 mg orally once per day) plus danazol placebo (ie, the momelotinib group) or danazol (300 mg orally twice per day) plus momelotinib placebo (ie, the danazol group), stratified by total symptom score (TSS; FINDINGS: 195 patients were randomly assigned to either the momelotinib group (130 [67%]) or danazol group (65 [33%]) and received study treatment in the 24-week randomised treatment period between April 24, 2020, and Dec 3, 2021. A significantly greater proportion of patients in the momelotinib group reported a 50% or more reduction in TSS than in the danazol group (32 [25%] of 130 vs six [9%] of 65; proportion difference 16% [95% CI 6-26], p=0·0095). The most frequent grade 3 or higher treatment-emergent adverse events with momelotinib and danazol were haematological abnormalities by laboratory values: anaemia (79 [61%] of 130 vs 49 [75%] of 65) and thrombocytopenia (36 [28%] vs 17 [26%]). The most frequent non-haematological grade 3 or higher treatment-emergent adverse events with momelotinib and danazol were acute kidney injury (four [3%] of 130 vs six [9%] of 65) and pneumonia (three [2%] vs six [9%]).INTERPRETATION: Treatment with momelotinib, compared with danazol, resulted in clinically significant improvements in myelofibrosis-associated symptoms, anaemia measures, and spleen response, with favourable safety. These findings support the future use of momelotinib as an effective treatment in patients with myelofibrosis, especially in those with anaemia.FUNDING: Sierra Oncology.

The JAK2V617F mutation is an acquired somatic mutation, which is prevalent in patients with the Philadelphia-chromosome negative myeloproliferative neoplasms (MPNs). In these diseases the mutation gives rise to constitutive JAK-STAT signaling with increased blood cell counts and in vivo activation of neutrophils and platelets as well, which altogether contribute to a chronic inflammatory and thrombogenic state with a 12-fold increased risk of coronary disease. Treatment with recombinant interferon-alpha2 (rIFN) reduces the JAK2V617F allelic burden in a large number of MPN-patients. Long-term treatment with rIFN associates with low-burden JAK2V617F in a subset of patients and a decreased thrombosis risk as well. In the general population the JAK2V617F mutation has been shown to associate with ischemic heart disease and thrombosis. Based upon the above observations we herein report the first patient with CHIP-JAK2V617F, in whom treatment with rIFN resolved severe angina pectoris. During a short period off rIFN the symptoms reappeared to resolve in concert with reduction of JAK2V617F allele burden, when rIFN was reinstituted. The JAK2V617F mutation may be a novel therapeutic target to prohibit the development of cardiovascular diseases using rIFN either as monotherapy or in combination with potent anti-inflammatory agents.

Aim: Evaluate health-related quality of life (HRQoL) and health utility impact of single-agent selinexor in heavily pretreated patients with relapsed/refractory diffuse large B-cell lymphoma. Patients & methods: Functional Assessment of Cancer Therapy (FACT) - Lymphoma and EuroQoL five-dimensions five-levels data collected in the single-arm Phase IIb trial SADAL (NCT02227251) were analyzed with mixed-effects models. Results: Treatment responders maintained higher FACT - Lymphoma (p = 3 adverse events and serious adverse events were not associated with clinically meaningful negative QoL impacts.

Patients with relapsed and refractory diffuse large B-cell lymphoma (DLBCL) have a poor prognosis and a median overall survival of less than 6 months. Outcomes and responses were evaluated in 134 patients with DLBCL administered selinexor. Our findings demonstrate that selinexor treatment in DLBCL patients can safely induce durable responses and improve outcomes regardless of prior treatments and refractory status. Background: Despite a number of treatment options, patients with diffuse large B-cell lymphoma (DLBCL) whose disease has become refractory to treatment have a poor prognosis. Selinexor is a novel, oral drug that is approved to treat patients with relapsed/refractory DLBCL. In this post hoc analysis of the SADAL study, a multinational, open-label study, we evaluated subpopulations to determine if response to single agent selinexor is impacted by number of lines of prior treatment, autologous stem cell transplant (ASCT), response to first and most recent therapies, and time to progressive disease. Patients: Patients (n = 134) with DLBCL after 2-5 prior therapies were enrolled in SADAL and received 60mg selinexor twice weekly. Results: The median overall survival was 9.0 months and median progression free survival was 2.6 months. Patients who had the best overall response rate (ORR) and disease control rate were those who had prior ASCT (42.5% and 50.0%) or responded to last line of therapy (35.9% and 43.5%). Patients with primary refractory DLBCL also showed responses (ORR 21.8%). Adverse events between subgroups were similar to the overall study population, the most common being thrombocytopenia (29.1%), fatigue (7.5%), and nausea (6.0%). Conclusion: Regardless of prior therapy and disease refractory status, selinexor treatment demonstrated results consistent with its novel mechanism of action and lack of cross-resistance. Thus, single agent oral selinexor can induce deep, durable, and tolerable responses in patients with DLBCL who have recurrent disease after several chemoimmunotherapy combination regimens.

Összefoglaló. Az akut myeloid leukaemia ellátása primeren hematológiai feladat, relapsusa során is ritka a sebészeti szövődmény. Esettanulmányunkban egy 46 éves férfi beteget mutatunk be, akinél rutinvérvétel során felfedezett akut promyelocytás leukaemia miatt történt hematológiai kezelés. Alapbetegsége komplett molekuláris remisszióba jutott, ezt követően fenntartó kezeléseket kapott, de betegsége kiújult. Reindukciós kezelést követően fehérvérsejtszáma normalizálódott, de nem jutott molekuláris remisszióba. További kezelés után a férfi testvérétől gyűjtött őssejttel allogén csontvelő-transzplantáció történt. Közel egy éve molekuláris remisszióban volt a beteg, amikor jelentkeztek jobb alhasi panaszai neutropenia, a C-reaktív protein magas értéke és pozitív hasi ultrahang mellett. Akutan laparoszkópos módszerrel távolítottuk el a láthatóan gyulladt féregnyúlványt. A hisztológiai feldolgozás során az akut promyelocytás leukaemia manifesztációja igazolódott. Tekintettel arra, hogy közben csontvelői relapsus is kialakult, újabb reindukciós kezelés, és másik testvérétől vett őssejtekkel ismételten allogén csontvelő-transzplantáció történt. Az általunk ismert irodalomban appendicitis képében jelentkező akut promyelocytás leukaemia relapsusáról nem találtunk közleményt, ezért tartottuk esetünket publikációra érdemesnek. Orv Hetil. 2020; 161(51): 2171–2174. Summary. The treatment of acute myeloid leukemia is primarily hematological. Surgical complications are rare even during relapse. We present the case of a 46-year-old man who was diagnosed with acute promyelocytic leukemia after a routine blood test. Following hematological treatment, molecular remission was achieved, and he was on maintenance therapy, when his leukemia relapsed. He received re-induction treatment and his white blood cell count normalised, however, molecular remission was not reached. After further treatment, allogeneic bone marrow transplantation was performed with stem cells collected from his brother. He developed right lower quadrant abdominal pain with neutropenia, elevated C-reactive protein and abdominal ultrasound report showed thickened appendix after nearly one year of molecular remission. We performed en emergency laparoscopic appendicectomy to remove the inflamed appendix. Histology confirmed acute promyelocytic leukemia manifestation in the appendix. Given the repeated bone marrow relapse, he received re-induction treatment and allogeneic bone marrow transplantation again with stem cells collected from his another brother. To the best of our knowledge, no previous report in the literature can be found of appendicitis mimicking relapse of acute promyelocytic leukemia, thus, this case report holds merit for publication. Orv Hetil. 2020; 161(51): 2171–2174.

Összefoglaló. Az acut myeloid leukemia a csontvelői eredetű hemopoetikus őssejtek malignus klonális betegsége. A betegség lefolyása, különösen a nagy dózisú kemoterápiára és allogén csontvelő-transzplantációra alkalmatlan betegek számára, a legutóbbi időkig szinte kivétel nélkül fatális volt. Az idős és/vagy leromlott állapotú acut myeloid leukemiás betegek kezelésében óriási áttörést hozott a Bcl2- (B-cell lymphoma 2) inhibitor – venetoclax és a hypomethyláló azacitidin kombinációja. Ötvenéves nőbetegünkön a normál karyotípusú, nucleophosmin 1 mutációval járó acut myeloid leukemia diagnózisa előtt szeptikus állapotot okozó végbéltályog miatt tehermentesítő colostomaképzést végeztünk. A széles spektrumú kombinált antibiotikus kezelés mellett is súlyosan elesett, szeptikus állapotú betegen a nagy dózisú, kuratív indukciós kezelést nem tartottuk kivitelezhetőnek, ezért venetoclax–azacitidin kombinációt alkalmaztunk. A beteg az első ciklus alatt az antibiotikus, antimycoticus kezelés mellett masszív hemoszupportációra szorult. A második ciklus alatt lényeges szövődményt már nem észleltünk, a ciklus végén elvégzett csontvelővizsgálat pedig komplett hematológiai remissziót igazolt. A páciens önellátóvá vált, a végbéltályog jelentősen javult. Az új kezelési lehetőség mellett elért remisszió, a beteg javuló általános állapota korábban ismeretlen problémát vet fel. Egy 50 éves beteg jó prognózisú eltéréssel járó acut myeloid leukemiájának ellátása a nagy dózisú kemoterápiával elért első remisszióban nem igényel allogén csontvelő-transzplantációt. „Nem kuratív” kezeléssel elért remisszióban hogyan folytassuk a kezelést? Summary. Acute myeloid leukemia is a clonal malignancy of bone marrow haemopoietic stem cells. Until recently the outcome of the disease has been almost without exemption fatal, especially in cases ineligible for high dose induction chemotherapy and bone marrow transplantation. The Bcl-2 inhibitor venetoclax-azacitidine combination is a breakthrough therapy for the elderly and frail AML patient. Prior to the diagnosis of normal karyotype NPM 1 mutant AML of our 50-year-old female patient a colostomy had been performed due to anal abscess leading to sepsis. The septic patient being extremely frail in spite of wide spectrum antibiotic treatment was deemed ineligible for high dose curative induction treatment, hence venetoclax-azacitidine combined treatment was used. During cycle 1 the patient needed massive transfusion support beside concomitant antibiotic and antimycotic medication. On course of cycle 2 no major complications were detected, BM evaluation at the end of cycle confirmed complete haemotologic remission. The abscess significantly improved, the patient’s self-care capability was restored. The remission induced by this new option and the improvement of the performance status of the patient raised hitherto unasked questions. In case of a patient aged 50, a favourable prognosis AML in remission following high dose induction does not mandate HSCT as a next step. How shall we follow the course of treatment in remission elicited by a ‘non-curative’ option?

Összefoglaló. A familiáris mediterrán láz a herediter autoinflammatorikus betegségek közé tartozik. Klinikai tüneteit döntően a savós hártyák akut gyulladása (serositis: peritonitis, pleuritis, synovitis, ritkán pericarditis, meningitis) határozza meg. A betegség hátterében a pyrin fehérjét kódoló MEFV-gén többségében autoszómális recesszív módon öröklődő mutációi állnak. Legfontosabb szövődménye az amyloidosis, amely veseelégtelenséghez vezethet. Kezelésében első vonalbeli terápiaként a colchicin szerepel. Fiatal nőbetegünket 12 éves kora óta több intézetben vizsgálták intenzív hasi fájdalommal és lázzal járó attakok miatt. A tünettan részeként hányás, hasmenés és mellkasi fájdalom jelentkezett. A gyulladásos epizódok 5–14 napig tartottak, a köztes időszakokban viszont teljesen jól volt. A rohamok alatt készült laboratóriumi vizsgálatok során leukocitózis, valamint emelkedett süllyedés és CRP mutatkozott. Intravazális hemolízisre utalt az anémia, retikulocitózis, magas Sebi, szérum szabad hemoglobin és LDH együttes megjelenése. Az EKG-én inferior és az anteroseptalis elvezetésekben átmenetileg negatív T-hullámok jelentek meg, ami pericarditis lehetőségét vetette fel. Fizikális státuszából kiemelendő a diszkrét, de progrediáló splenomegalia. Kizártuk a porphyriat, glucose-6-phosphat dehydrogenase-hiányt, PNH-t és C1-inhibitorhiányt. Az autoinflammatorikus betegség miatt elvégzett molekuláris genetikai vizsgálat az MEFV-génmutáció homozigóta formáját, a Familiáris mediterrán láz diagnózisát igazolta. Summary. The familial Mediterranean fever is one of the hereditary autoinflammatory diseases. Its clinical symptoms are mainly determined by acute inflammation of the serous membranes (serositis: peritonitis, pleurisy, synovitis, rarely, pericarditis, meningitis). The background of the disease is mostly represented by autosomal recessively inherited mutations in the MEFV gene encoding the pyrine protein. Its most important complication is amyloidosis, which can lead to renal failure. Colchicine is included in its treatment, as a first-line therapy. Our young female patient has been examined in several institutions since the age of 12 for attacks of intense abdominal pain and fever. The symptoms included vomiting, diarrhea, and chest pain. The inflammatory episodes lasted 5–14 days, but in the intervening periods she was free of symptoms. Laboratory tests performed during the inflammatory periods showed leukocytosis as well as increased ESR and CRP. Intravascular hemolysis was indicated by anemia, reticulocytosis, co-occurrence of high Sebi, serum free hemoglobin and LDH. On the ECG, transiently negative T waves appeared in the inferior and anteroseptal leads, raising the possibility of pericarditis. Of her clinical status, discrete but progressive splenomegaly should be highlighted. Porphyria, glucose-6-phosphat dehydrogenase deficiency, PNH, and C1 inhibitor deficiency were excluded during our examinations. Molecular genetic testing urged by autoinflammatory disease confirmed a homozygous form of the MEFV gene mutation and established the diagnosis of familial Mediterranean fever.

Polycythemia vera (PV) is a Philadelphia chromosome-negative chronic myeloproliferative neoplasm (MPN). A newly developed PV treatment option, ropeginterferon alfa-2b, contains recombinant human alfa monoisomer as an active ingredient, resulting in a novel pharmacologic profile and improved tolerability. Efficacy studies conclude remarkable long-term hematological response and sustained JAK2V617F allele burden reduction. Ropeginterferon alfa-2b compound has been approved for the treatment of polycythemia vera without symptomatic splenomegaly.Current clinical trials are investigating the role of ropeginterferon alfa-2b in the first-line setting of treatment for PV. The safety and efficacy results of completed trials are summarized in this review. Metabolic, pharmacokinetic issues are also discussed of ropeginterferon alfa-2b.Ropeginterferon alfa-2b is a targeted therapeutic option in the treatment of PV, representing a significant improvement compared to conventional cytoreductive therapies. The single isomer entity of the recombinant human interferon alfa-2b and the mono-pegylation method imparts favorable properties to the compound. The use of ropeginterferon alfa-2b allows extended dosing interval, reduces side effects, and may increase the overall survival of PV patients by reducing the risk of progression to myelofibrosis or acute leukemia. Clinical data suggests that the compound may provide a disease-modifying option for PV patients with asymptomatic splenomegaly.

The authors present a case of a 36 year- old male patients, with St. IB mycosis fungoides with extensive skin symptoms. They decided acitretin monotherapy, as first line treatment. The patient responded well, and became permanently asymptomatic. The authors provide a brief literature review of the role of acitretin in the treatment of mycosis fungoides.

BACKGROUND: Relapsed or refractory diffuse large B-cell lymphoma (DLBCL) is an aggressive cancer with a median overall survival of less than 6 months. We aimed to assess the response to single-agent selinexor, an oral selective inhibitor of nuclear export, in patients with relapsed or refractory DLBCL who had no therapeutic options of potential clinical benefit. METHODS: SADAL was a multicentre, multinational, open-label, phase 2b study done in 59 sites in 19 countries. Patients aged 18 years or older with pathologically confirmed diffuse large B-cell lymphoma, an Eastern Cooperative Oncology Group performance status of 2 or less, who had received two to five lines of previous therapies, and progressed after or were not candidates for autologous stem-cell transplantation were enrolled. Germinal centre B-cell or non-germinal centre B-cell tumour subtype and double or triple expressor status were determined by immunohistochemistry and double or triple hit status was determined by cytogenetics. Patients received 60 mg selinexor orally on days 1 and 3 weekly until disease progression or unacceptable toxicity. The study was initially designed to evaluate both 60 mg and 100 mg twice-weekly doses of selinexor; however, the 100 mg dose was discontinued in the protocol (version 7.0) on March 29, 2017, when an improved therapeutic window was observed at 60 mg. Primary outcome was overall response rate. The primary outcome and safety were assessed in all patients who received 60 mg selinexor under protocol version 6.0, or enrolled under protocol versions 7.0 or higher and received at least one dose of selinexor. This trial is registered at ClinicalTrials.gov, NCT02227251 (active but not enrolling). FINDINGS: Between Oct 21, 2015, and Nov 2, 2019, 267 patients were randomly assigned, with 175 allocated to the 60 mg group and 92 to the discontinued 100 mg group. 48 patients assigned to the 60 mg group were excluded due to enrolment before version 6.0 of the protocol; the remaining 127 patients received selinexor 60 mg and were included in analyses of primary outcome and safety. The overall response rate was 28% (36/127; 95% CI 20·7-37·0); 15 (12%) achieved a complete response and 21 (17%) a partial response. The most common grade 3-4 adverse events were thrombocytopenia (n=58), neutropenia (n=31), anaemia (n=28), fatigue (n=14), hyponatraemia (n=10), and nausea (n=8). The most common serious adverse events were pyrexia (n=9), pneumonia (n=6), and sepsis (n=6). There were no deaths judged as related to treatment with selinexor. INTERPRETATION: Single-drug oral selinexor induced durable responses and had a manageable adverse events profile in patients with relapsed or refractory DLBCL who received at least two lines of previous chemoimmunotherapy. Selinexor could be considered a new oral, non-cytotoxic treatment option in this setting. FUNDING: Karyopharm Therapeutics Inc.

We report an extension study of patients with essential thrombocythaemia (ET) in the Hungarian Myeloproliferative Neoplasm (HUMYPRON) Registry, which demonstrated that over 6 years anagrelide significantly decreased the number of patients experiencing minor arterial and minor venous thrombotic events (TEs) vs hydroxyurea+aspirin.Data on patients with ET were collected through completion of a questionnaire developed according to 2008 WHO diagnostic criteria and with regard to Landolfi, Tefferi and IPSET criteria for thrombotic risk. Data were entered into the registry from 14 haematological centres. TEs, secondary malignancies, disease progression and survival were compared between patients with ET treated with anagrelide (n = 116) and with hydroxyurea+aspirin (n = 121).Patients were followed for (median) 10 years. A between-group difference in the number of patients with TEs was observed (25.9% anagrelide vs 38.0% hydroxyurea+aspirin; P = .052). Minor arterial events were more frequently reported in the hydroxyurea+aspirin group (P .001); there were marginally more reports of major arterial events in the anagrelide group (P = .049). TE prior to diagnosis was found to significantly influence TE incidence (P .001). Progression-free survival (P = .004) and survival (P = .001) were significantly increased for the anagrelide group vs hydroxyurea+aspirin.Anagrelide reduced TEs, and increased progression-free and overall survival vs hydroxyurea+aspirin over (median) 10 years.

Complement C5 inhibition is the standard of care (SoC) for patients with paroxysmal nocturnal hemoglobinuria (PNH) with significant clinical symptoms. Constant and complete suppression of the terminal complement pathway and the high serum concentration of C5 pose challenges to drug development that result in IV-only treatment options. Crovalimab, a sequential monoclonal antibody recycling technology antibody was engineered for extended self-administered subcutaneous dosing of small volumes in diseases amenable for C5 inhibition. A 3-part open-label adaptive phase 1/2 trial was conducted to assess safety, pharmacokinetics, pharmacodynamics, and exploratory efficacy in healthy volunteers (part 1), as well as in complement blockade–naive (part 2) and C5 inhibitor–treated (part 3) PNH patients. Twenty-nine patients were included in part 2 (n = 10) and part 3 (n = 19). Crovalimab concentrations exceeded the prespecified 100-µg/mL level and resulted in complete and sustained terminal complement pathway inhibition in treatment-naive and C5 inhibitor–pretreated PNH patients. Hemolytic activity and free C5 levels were suppressed below clinically relevant thresholds (liposome assay

Summary Background The PROUD-PV and CONTINUATION-PV trials aimed to compare the novel monopegylated interferon ropeginterferon alfa-2b with hydroxyurea, the standard therapy for patients with polycythaemia vera, over 3 years of treatment. Methods PROUD-PV and its extension study, CONTINUATION-PV, were phase 3, randomised, controlled, open-label, trials done in 48 clinics in Europe. Patients were eligible if 18 years or older with early stage polycythaemia vera (no history of cytoreductive treatment or less than 3 years of previous hydroxyurea treatment) diagnosed by WHO's 2008 criteria. Patients were randomly assigned 1:1 to ropeginterferon alfa-2b (subcutaneously every 2 weeks, starting at 100 μg) or hydroxyurea (orally starting at 500 mg/day). After 1 year, patients could opt to enter the extension part of the trial, CONTINUATION-PV. The primary endpoint in PROUD-PV was non-inferiority of ropeginterferon alfa-2b versus hydroxyurea regarding complete haematological response with normal spleen size (longitudinal diameter of ≤12 cm for women and ≤13 cm for men) at 12 months; in CONTINUATION-PV, the coprimary endpoints were complete haematological response with normalisation of spleen size and with improved disease burden (ie, splenomegaly, microvascular disturbances, pruritus, and headache). We present the final results of PROUD-PV and an interim analysis at 36 months of the CONTINUATION-PV study (per statistical analysis plan). Analyses for safety and efficacy were per-protocol. The trials were registered on EudraCT, 2012-005259-18 (PROUD-PV) and 2014-001357-17 (CONTINUATION-PV, which is ongoing). Findings Patients were recruited from Sept 17, 2013 to March 13, 2015 with 306 enrolled. 257 patients were randomly assigned, 127 were treated in each group (three patients withdrew consent in the hydroxyurea group), and 171 rolled over to the CONTINUATION-PV trial. Median follow-up was 182·1 weeks (IQR 166·3–201·7) in the ropeginterferon alfa-2b and 164·5 weeks (144·4–169·3) in the standard therapy group. In PROUD-PV, 26 (21%) of 122 patients in the ropeginterferon alfa-2b group and 34 (28%) of 123 patients in the standard therapy group met the composite primary endpoint of complete haematological response with normal spleen size. In CONTINUATION-PV, complete haematological response with improved disease burden was met in 50 (53%) of 95 patients in the ropeginterferon alfa-2b group versus 28 (38%) of 74 patients in the hydroxyurea group, p=0·044 at 36 months. Complete haematological response without the spleen criterion in the ropeginterferon alfa-2b group versus standard therapy group were: 53 (43%) of 123 patients versus 57 (46%) of 125 patients, p=0·63 at 12 months (PROUD-PV), and 67 (71%) of 95 patients versus 38 (51%) of 74 patients, p=0·012 at 36 months (CONTINUATION-PV). The most frequently reported grade 3 and grade 4 treatment-related adverse events were increased γ-glutamyltransferase (seven [6%] of 127 patients) and increased alanine aminotransferase (four [3%] of 127 patients) in the ropeginterferon alfa-2b group, and leucopenia (six [5%] of 127 patients) and thrombocytopenia (five [4%] of 127 patients) in the standard therapy group. Treatment-related serious adverse events occurred in three (2%) of 127 patients in the ropeginterferon alfa-2b group and five (4%) of 127 patients in the hydroxyurea group. One treatment-related death was reported in the standard therapy group (acute leukaemia). Interpretation In patients with early polycythaemia vera, who predominantly presented without splenomegaly, ropeginterferon alfa-2b was effective in inducing haematological responses; non-inferiority to hydroxyurea regarding haematological response and normal spleen size was not shown at 12 months. However, response to ropeginterferon alfa-2b continued to increase over time with improved responses compared with hydroxyurea at 36 months. Considering the high and durable haematological and molecular responses and its good tolerability, ropeginterferon alfa-2b offers a valuable and safe long-term treatment option with features distinct from hydroxyurea.

Bruton’s tyrosine kinase inhibitors have changed the treatment landscape for chronic lymphocytic leukemia (CLL), mantle cell lymphoma (MCL) and lymphoplasmacytic lymphoma dramatically. In 2019, acalabrutinib was approved by the US FDA for the treatment of treatment-naive and relapsed/refractory CLL and MCL. Acalabrutinib monotherapy was found to be effective and safe in CLL patients. In ASCEND and ELEVATE treatment-naive studies, acalabrutinib monotherapy and the combination with obinutuzumab demonstrated improved efficacy and an acceptable safety profile. The triple combination with venetoclax showed a high rate of molecular remission without an impaired safety profile. Adverse events, with an occurrence rate of >20%, were as follows: grade 1–2 myelosuppression, gastrointestinal toxicity, rash, constitutional symptoms; grade 3 or 4 toxicities were syncope, pneumonia, hypertension, atrial fibrillation, neutropenia and thrombocytopenia.

The phase 2b, open-label, multicenter SADAL study evaluated single agent oral selinexor, a selective inhibitor of nuclear export (SINE) compound, in patients with diffuse large B cell lymphoma (DLBCL) after >= 2 lines of systemic therapy. Similar activity was observed in GCB- and non-GCB DLBCL with a trend to higher response rates in DLBCL transformed from follicular lymphoma. Lower response rates were observed in double expressor DLBCL; higher response rates were observed in patients with baseline hemoglobin >= 10 g/dL and normal levels of C-MYC or BCL-2 expression (51%). Overall, strong single agent activity with selinexor were observed in patients with relapsed/refractory DLBCL.Background: The SADAL study evaluated oral selinexor in patients with relapsed and/or refractory diffuse large B-cell lymphoma (DLBCL) after at least 2 prior lines of systemic therapy. In this post-hoc analysis, we analyzed the outcomes of the SADAL study by DLBCL subtype to determine the effects of DLBCL subtypes on efficacy and tolerability of selinexor. Patients and Methods: Data from 134 patients in SADAL were analyzed by DLBCL subtypes for overall response rate (ORR), overall survival (OS), duration of treatment response, progression-free survival, and adverse events rate. Results: ORR in the entire cohort was 29.1%, and similar in patients with germinal center (GCB) versus non-GCB DLBCL (31.7% vs. 24.2%, P = 0.45); transformed DLBCL showed a trend towards higher ORR than de novo DLBCL: 38.7% vs. 26.2% (P = 0.23). Despite similar prior treatment regimens and baseline characteristics, patients with DLBCL and normal C-MYC/BCL-2 protein expression levels had a significantly higher ORR (46.2% vs.14.8%, P = 0.012) and significantly longer OS (medians 13.7 vs. 5.1 months, hazard ratio 0.43 [95% CI, 0.23-0.77], P = 0.004) as compared with those whose DLBCL had C-MYC and BCL-2 overexpression. Among patients who had normal expression levels of either C-MYC or BCL-2 and baseline hemoglobin levels >= 10g/dL, ORR was 51.5% (n = 47), with median OS of 15.5 months and median PFS of 4.6 months. Similar rates of adverse events were noted in all subgroups. Conclusions: Overall, single agent oral selinexor showed strong responses in patients with limited treatment alternatives regardless of germinal center B-cell type or disease origin.

MMB, an oral JAK1/2 and ACVR1/ALK2 inhibitor, was evaluated (vs DAN) in a pivotal phase 3 study of MF patients previously treated with a JAK inhibitor (JAKi). This subgroup analysis evaluated MOMENTUM patients with baseline platelet counts ≤150 × 10Eligibility: Primary or post-ET/PV MF; DIPSS high risk, Int-2, or Int-1; total symptom score (TSS) ≥10; hemoglobin10 g/dL; prior JAKi ≥90 days, or ≥28 days if RBC transfusions ≥4 units in 8 weeks or Grade 3/4 thrombocytopenia, anemia, or hematoma; palpable spleen ≥5 cm; platelets ≥25 × 10TSS response (≥50% reduction from baseline) rate at week 24. Secondary endpoints at week 24: transfusion independence (TI) rate, splenic response rate (SRR; ≥25% volume reduction from baseline), TSS change from baseline, SRR (≥35% reduction), and rate of zero transfusions since baseline.Mean baseline TSS: 29 MMB, 26 DAN, hemoglobin: 8.1 MMB, 7.8 DAN g/dL, and platelets: 74 × 10In symptomatic, anemic, and thrombocytopenic MF patients, MMB was superior to DAN for symptom responses, transfusion requirements, and spleen responses with comparable safety and favorable survival. MMB may address a critical unmet need in thrombocytopenic MF patients. NCT04173494.

7061 Background: MMB, an oral JAK1/2 and ACVR1/ALK2 inhibitor, showed clinical activity on MF symptoms, RBC transfusion requirements (anemia), and spleen volume in the SIMPLIFY trials, including in MF patients (pts) with thrombocytopenia. MOMENTUM is a pivotal phase 3 study of symptomatic and anemic MF pts previously treated with a JAK inhibitor (JAKi) testing MMB vs DAN. This analysis evaluated MOMENTUM pts with baseline (BL) platelet counts (PLT) ≤150 x 109/L. Methods: Eligibility: Primary or post-ET/PV MF; DIPSS high risk, Int-2, or Int-1; MF Symptom Assessment Form Total Symptom Score (MFSAF TSS) ≥10; Hgb 9/L. JAKi taper and washout was ≥21 days. Randomization: 2:1 to MMB 200 mg QD plus DAN placebo or DAN 600 mg QD plus MMB placebo for 24 wks. Primary endpoint: TSS response (≥50% reduction from BL) rate at wk 24. Key secondary endpoints, assessed sequentially at wk 24: RBC transfusion independence (TI) rate, splenic response rate (SRR; ≥25% reduction in volume from BL), change from BL in TSS, SRR (≥35% reduction from BL) and rate of zero transfusions since BL. Results: 60 (74%) of 81 MMB pts and 25 (58%) of 43 DAN pts with BL PLT ≤150 x 109/L completed the 24-week randomized treatment (RT) phase. Median BL TSS were 29 (MMB) and 24 (DAN), Hgb were 7.9 (MMB) and 8.0 (DAN) g/dL, and PLT were 67 x 109/L (MMB) and 64 x 109/L (DAN). Prior JAKi was ruxolitinib in 124 pts (100%) and fedratinib in 6 pts (5%). Efficacy results are in Table. These results are consistent with the overall ITT analysis set (N=195). Most common Gr ≥3 TEAEs in the RT phase were thrombocytopenia (MMB, 31%; DAN, 16%) and anemia (MMB, 7%; DAN, 14%); Gr ≥3 bleeding events occurred in 9% of MMB and 5% of DAN pts. TEAEs led to study drug discontinuation in 15% of MMB and 19% of DAN pts in RT phase. A trend toward improved OS up to wk 24 was seen with MMB vs DAN [HR (95% CI)=0.490 (0.195, 1.235)]. Additional analyses of pts with BL PLT 9/L (N=100) and BL PLT 9/L (N=31) show similar treatment effects of MMB vs DAN. Conclusions: In thrombocytopenic MF pts who were symptomatic and anemic, MMB was superior to DAN for symptom responses, transfusion requirements, and spleen responses and showed comparable safety and favorable survival. MMB may address a critical unmet need in thrombocytopenic MF pts. Clinical trial information: NCT04173494. [Table: see text]

7002 Background: MMB, an oral JAK1/2 and ACVR1/ALK2 inhibitor, showed clinical activity on MF symptoms, RBC transfusion requirements (anemia), and spleen volume in the SIMPLIFY trials. This pivotal phase 3 study of MF patients (pts) previously treated with a JAK inhibitor (JAKi) tested MMB vs DAN on key symptom, anemia, and spleen volume endpoints at 24 weeks (wks). Methods: Eligibility: Primary or post-ET/PV MF; DIPSS high risk, Int-2, or Int-1; MF Symptom Assessment Form Total Symptom Score (MFSAF TSS) ≥10; Hgb 9/L. BL TI was 13% (MMB) and 15% (DAN). Prior JAKi was ruxolitinib in 195 pts (100%) and fedratinib in 9 pts (5%). All primary and key secondary endpoints were met (Table). Most common Gr ≥3 TEAEs in the RT phase of the study were thrombocytopenia (MMB, 22%; DAN, 12%) and anemia (MMB, 8%; DAN, 11%). Gr ≥3 infections occurred in 15% of MMB and 17% of DAN pts. Peripheral neuropathy occurred in 5 (4%) of MMB (all Gr ≤2) and 1 (2%) of DAN (Gr ≤2) pts in the RT phase, and none discontinued study drug. Overall, TEAEs led to study drug discontinuation in 18% of MMB and 23% of DAN pts in RT phase. A trend toward improved OS up to wk 24 was seen with MMB vs DAN (HR=0.506, p=0.0719). Conclusions: In symptomatic and anemic MF pts, MMB was superior to DAN for symptom responses, transfusion requirements, and spleen responses with comparable safety and favorable survival. MMB may address a critical unmet need, particularly in MF pts with anemia. Clinical trial information: NCT04173494. [Table: see text]

7539 Background: For ELEVATE-TN (NCT02475681), we previously reported superior efficacy of acalabrutinib (A) ± obinutuzumab (O) vs O + chlorambucil (Clb) in patients (pts) with treatment-naive (TN) chronic lymphocytic leukemia (CLL) at 28.3 and 46.9 months (mo) median follow-up. Now, we report results from a 5-y update. Methods: Pts were randomized to A+O, A, or O+Clb. Pts who progressed on O+Clb could cross over to A monotherapy. Investigator-assessed (INV) progression-free survival (PFS), INV overall response rate (ORR), overall survival (OS), and safety were evaluated. Results: A total of 535 pts (A+O, n=179; A, n=179; O+Clb, n=177) had a median age of 70 y. At a median follow-up of 58.2 mo (range, 0.0–72.0; data cutoff Oct 1, 2021), median PFS was not reached (NR) (hazard ratio [HR]: 0.11) for A+O and A (HR: 0.21) vs 27.8 mo for O+Clb (both P

Context: Results from ELEVATE-TN (NCT02475681) at a median follow-up of 28.3 months demonstrated superior efficacy of acalabrutinib (A) ± obinutuzumab (O) compared with O + chlorambucil (Clb) in TN CLL (Sharman et al. Lancet 2020;395:1278-91). Objective: To report the results from a 4-year update of ELEVATE-TN. Design: Randomized, multicenter, open-label, 3-arm, Phase 3 study. Patients: TN CLL. Interventions: Patients received A±O or O+Clb. Crossover to A monotherapy was permitted in patients who progressed on O+Clb. Main Outcome Measures: Investigator-assessed (INV) progression-free survival PFS, INV ORR, OS, and safety were evaluated. Results: 535 patients (A+O, n=179; A, n=179; O+Clb, n=177) were randomized with a median age of 70 y; 14% had del(17p) and/or mutated TP53. At a median follow-up of 46.9 months (range, 0.0–59.4; data cutoff: Sept 11, 2020), median PFS was not reached (NR) for A+O and A patients vs 27.8 months for O+Clb patients (both P Conclusions: With a median follow-up of 46.9 months (~4y), the efficacy and safety of A+O and A monotherapy was maintained, with an increase in CR since the interim analysis (from 21% to 27% [A+O] and from 7% to 11% [A]) and low rates of discontinuation.

Hallmark features of myelofibrosis (MF) are cytopenias, constitutional symptoms and splenomegaly. Anemia and transfusion dependency are among the most important negative prognostic factors and are exacerbated by many JAK inhibitors (JAKi). Momelotinib (MMB) has been investigated in over 820 patients with MF and possesses a pharmacological and clinical profile differentiated from other JAKi by inhibition of JAK1, JAK2 and ACVR1. MMB is designed to address the complex drivers of iron-restricted anemia and chronic inflammation in MF and should improve constitutional symptoms and splenomegaly while maintaining or improving hemoglobin in JAKi-naive and previously JAKi-treated patients. The MOMENTUM Phase III study is designed to confirm and extend observations of safety and clinical activity of MMB.Lay abstract The most important features of myelofibrosis (MF) are low blood cell counts and symptoms including tiredness, night sweats and itching, along with increased size of the spleen, which may cause a feeling of fullness and pain. Low red blood cell counts (anemia) may mean regular blood transfusions are needed and this is one of the signs MF is getting worse. Drugs called JAK inhibitors (JAKi) are available to treat MF, but can have a side effect of making blood cell counts lower. Momelotinib (MMB) is a different type of JAKi to the ones currently available, and is an experimental drug for MF. MMB is designed to treat symptoms and spleen like other JAKi, but also to improve blood cell counts. MMB has already been given to more than 820 patients with MF in other clinical studies. Some of the patients in these studies had been treated with different JAKi before, and others got MMB as their first JAKi treatment. The MOMENTUM Phase III study is designed to collect more information on the safety and effectiveness of MMB in MF.

The Bruton's tyrosine kinase (BTK) inhibitor ibrutinib has revolutionised the therapeutic landscape of chronic lymphocytic leukaemia (CLL). Acquired mutations emerging at position C481 in the BTK tyrosine kinase domain are the predominant genetic alterations associated with secondary ibrutinib resistance. To assess the correlation between disease progression, and the emergence and temporal dynamics of the most common resistance mutation BTKC481S , sensitive (10-4 ) time-resolved screening was performed in 83 relapsed/refractory CLL patients during single-agent ibrutinib treatment. With a median follow-up time of 40 months, BTKC481S was detected in 48·2% (40/83) of the patients, with 80·0% (32/40) of them showing disease progression during the examined period. In these 32 cases, representing 72·7% (32/44) of all patients experiencing relapse, emergence of the BTKC481S mutation preceded the symptoms of clinical relapse with a median of nine months. Subsequent Bcl-2 inhibition therapy applied in 28/32 patients harbouring BTKC481S and progressing on ibrutinib conferred clinical and molecular remission across the patients. Our study demonstrates the clinical value of sensitive BTKC481S monitoring with the largest longitudinally analysed real-world patient cohort reported to date and validates the feasibility of an early prediction of relapse in the majority of ibrutinib-treated relapsed/refractory CLL patients experiencing disease progression.

Summary Background Isatuximab is an anti-CD38 monoclonal antibody approved in combination with pomalidomide–dexamethasone and carfilzomib–dexamethasone for relapsed or refractory multiple myeloma. This phase 3, open-label study compared the efficacy of isatuximab plus carfilzomib–dexamethasone versus carfilzomib–dexamethasone in patients with relapsed multiple myeloma. Methods This was a prospective, randomised, open-label, parallel-group, phase 3 study done at 69 study centres in 16 countries across North America, South America, Europe, and the Asia-Pacific region. Patients with relapsed or refractory multiple myeloma aged at least 18 years who had received one to three previous lines of therapy and had measurable serum or urine M-protein were eligible. Patients were randomly assigned (3:2) to isatuximab plus carfilzomib–dexamethasone (isatuximab group) or carfilzomib–dexamethasone (control group). Patients in the isatuximab group received isatuximab 10 mg/kg intravenously weekly for the first 4 weeks, then every 2 weeks. Both groups received the approved schedule of intravenous carfilzomib and oral or intravenous dexamethasone. Treatment continued until progression or unacceptable toxicity. The primary endpoint was progression-free survival and was assessed in the intention-to-treat population according to assigned treatment. Safety was assessed in all patients who received at least one dose according to treatment received. The study is registered at ClinicalTrials.gov, NCT03275285. Findings Between Nov 15, 2017, and March 21, 2019, 302 patients with a median of two previous lines of therapy were enrolled. 179 were randomly assigned to the isatuximab group and 123 to the control group. Median progression-free survival was not reached in the isatuximab group compared with 19·15 months (95% CI 15·77–not reached) in the control group, with a hazard ratio of 0·53 (99% CI 0·32–0·89; one-sided p=0·0007). Treatment-emergent adverse events (TEAEs) of grade 3 or worse occurred in 136 (77%) of 177 patients in the isatuximab group versus 82 (67%) of 122 in the control group, serious TEAEs occurred in 105 (59%) versus 70 (57%) patients, and TEAEs led to discontinuation in 15 (8%) versus 17 (14%) patients. Fatal TEAEs during study treatment occurred in six (3%) versus four (3%) patients. Interpretation The addition of isatuximab to carfilzomib–dexamethasone significantly improves progression-free survival and depth of response in patients with relapsed multiple myeloma, representing a new standard of care for this patient population.

PAC203 is a randomized dose-finding study of pacritinib, an oral JAK2/IRAK1 inhibitor, in patients with advanced myelofibrosis who are intolerant of or resistant to ruxolitinib. Patients were randomized 1:1:1 to pacritinib 100 mg once per day, 100 mg twice per day, or 200 mg twice per day. Enhanced eligibility criteria, monitoring, and dose modifications were implemented to mitigate risk of cardiac and hemorrhagic events. Efficacy was based on ≥35% spleen volume response (SVR) and ≥50% reduction in the 7-component total symptom score (TSS) through week 24. Of 161 patients, 73% were intolerant of and 76% had become resistant to ruxolitinib; 50% met criteria for both. Severe thrombocytopenia (platelet count

Summary Background In the LYM-3002 study, the efficacy and safety of frontline bortezomib plus rituximab, cyclophosphamide, doxorubicin, and prednisone (VR-CAP) and rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) were compared in transplant-ineligible patients with untreated, newly diagnosed, mantle cell lymphoma. We report the final overall survival and safety outcomes for patients in the long-term follow-up phase after the primary progression-free-survival endpoint was met. Methods LYM-3002 was a randomised, open-label, phase 3 study done at 128 clinical centres in 28 countries in Asia, Europe, North America, and South America. Adult patients with confirmed stage II–IV previously untreated mantle cell lymphoma, Eastern Cooperative Oncology Group performance status score of 2 or less, who were ineligible for bone marrow transplantation, were randomly assigned (1:1) to receive six or eight 21-day cycles of VR-CAP (intravenous rituximab 375 mg/m2, cyclophosphamide 750 mg/m2, doxorubicin 50 mg/m2, and bortezomib 1·3 mg/m2, plus oral prednisone 100 mg/m2) or R-CHOP (intravenous vincristine 1·4 mg/m2 [2 mg maximum], rituximab 375 mg/m2, cyclophosphamide 750 mg/m2, and doxorubicin 50 mg/m2, plus oral prednisone 100 mg/m2). Randomisation was done according to a computer-generated randomisation schedule prepared by the sponsor; permuted blocks central randomisation was used (block size of 4), and was stratified by International Prognostic Index score and disease stage at diagnosis. The primary endpoint of this final analysis was overall survival, which was analysed in the intention-to-treat population. This study is registered with ClinicalTrials.gov , number NCT00722137 , and is closed to new participants with follow-up completed. Findings Between May 22, 2008, and Dec 5, 2011, 487 patients were enrolled and randomly assigned. 268 patients (140 in the VR-CAP group and 128 in the R-CHOP group) were included in the follow-up analysis, which included patients with data available after the primary analysis clinical cutoff date of Dec 2, 2013. After median follow-up of 82·0 months (IQR 74·1–94·2), median overall survival was significantly longer in the VR-CAP group than in the R-CHOP group (90·7 months [95% CI 71·4 to not estimable] vs 55·7 months [47·2 to 68·9]; hazard ratio 0·66 [95% CI 0·51–0·85]; p=0·001). Three new adverse events were reported since the primary analysis cutoff (one each of grade 4 lung adenocarcinoma and grade 4 gastric cancer in the VR-CAP group, and one case of grade 2 pneumonia in the R-CHOP group). 103 (42%) of 243 patients in the VR-CAP group, and 138 (57%) of 244 in the R-CHOP group died; the most common cause of death was progressive disease. Interpretations Compared with R-CHOP, VR-CAP was associated with significantly longer survival, and had a manageable and expected safety profile. Our results support further assessment of VR-CAP in patients with previously untreated mantle cell lymphoma. Funding Janssen Research & Development.

Objective: To present the Central European Myeloproliferative Neoplasm Organisation (CEMPO) treatment recommendations for polycythaemia vera (PV). Methods: During meetings held from 2015 through 2017, CEMPO discussed PV and its treatment and recent data. Results: PV is associated with increased risks of thrombosis/thrombo-haemorrhagic complications, fibrotic progression and leukaemic transformation. Presence of Janus kinase (JAK)-2 gene mutations is a diagnostic marker and standard diagnostic criterion. World Health Organization 2016 diagnostic criteria for PV, focusing on haemoglobin levels and bone marrow morphology, are mandatory. PV therapy aims at managing long-term risks of vascular complications and progression towards transformation to acute myeloid leukaemia and myelodysplastic syndrome. Risk stratification for thrombotic complications guides therapeutic decisions. Low-risk patients are treated first line with low-dose aspirin and phlebotomy. Cytoreduction is considered for low-risk (phlebotomy intolerance, severe/progressive symptoms, cardiovascular risk factors) and high-risk patients. Hydroxyurea is suspected of leukaemogenic potential. IFN- has demonstrated efficacy in many clinical trials;its pegylated form is best tolerated, enabling less frequent administration than standard interferon. Ropeginterferon alfa-2b has been shown to be more efficacious than hydroxyurea. JAK1/JAK2 inhibitor ruxolitinib is approved for hydroxyurea resistant/intolerant patients. Conclusion: sGreater understanding of PV is serving as a platform for new therapy development and treatment response predictors.
