Background: First-line durvalumab plus etoposide with either cisplatin or carboplatin (platinum–etoposide) showed a significant improvement in overall survival versus platinum–etoposide alone in patients with extensive-stage small-cell lung cancer (ES-SCLC) in the CASPIAN study. Here we report updated results, including the primary analysis for overall survival with durvalumab plus tremelimumab plus platinum–etoposide versus platinum–etoposide alone. Methods: CASPIAN is an ongoing, open-label, sponsor-blind, randomised, controlled phase 3 trial at 209 cancer treatment centres in 23 countries worldwide. Eligible patients were aged 18 years or older (20 years in Japan) and had treatment-naive, histologically or cytologically documented ES-SCLC, with a WHO performance status of 0 or 1. Patients were randomly assigned (1:1:1) in blocks of six, stratified by planned platinum, using an interactive voice-response or web-response system to receive intravenous durvalumab plus tremelimumab plus platinum–etoposide, durvalumab plus platinum–etoposide, or platinum–etoposide alone. In all groups, patients received etoposide 80–100 mg/m2 on days 1–3 of each cycle with investigator's choice of either carboplatin area under the curve 5–6 mg/mL/min or cisplatin 75–80 mg/m2 on day 1 of each cycle. Patients in the platinum–etoposide group received up to six cycles of platinum–etoposide every 3 weeks and optional prophylactic cranial irradiation (investigator's discretion). Patients in the immunotherapy groups received four cycles of platinum–etoposide plus durvalumab 1500 mg with or without tremelimumab 75 mg every 3 weeks followed by maintenance durvalumab 1500 mg every 4 weeks. The two primary endpoints were overall survival for durvalumab plus platinum–etoposide versus platinum–etoposide and for durvalumab plus tremelimumab plus platinum–etoposide versus platinum–etoposide in the intention-to-treat population. Safety was assessed in all patients who received at least one dose of study treatment. This study is registered at ClinicalTrials.gov, NCT03043872. Findings: Between March 27, 2017, and May 29, 2018, 972 patients were screened and 805 were randomly assigned (268 to durvalumab plus tremelimumab plus platinum–etoposide, 268 to durvalumab plus platinum–etoposide, and 269 to platinum–etoposide). As of Jan 27, 2020, the median follow-up was 25·1 months (IQR 22·3–27·9). Durvalumab plus tremelimumab plus platinum–etoposide was not associated with a significant improvement in overall survival versus platinum–etoposide (hazard ratio [HR] 0·82 [95% CI 0·68–1·00]; p=0·045); median overall survival was 10·4 months (95% CI 9·6–12·0) versus 10·5 months (9·3–11·2). Durvalumab plus platinum–etoposide showed sustained improvement in overall survival versus platinum–etoposide (HR 0·75 [95% CI 0·62–0·91]; nominal p=0·0032); median overall survival was 12·9 months (95% CI 11·3–14·7) versus 10·5 months (9·3–11·2). The most common any-cause grade 3 or worse adverse events were neutropenia (85 [32%] of 266 patients in the durvalumab plus tremelimumab plus platinum–etoposide group, 64 [24%] of 265 patients in the durvalumab plus platinum–etoposide group, and 88 [33%] of 266 patients in the platinum–etoposide group) and anaemia (34 [13%], 24 [9%], and 48 [18%]). Any-cause serious adverse events were reported in 121 (45%) patients in the durvalumab plus tremelimumab plus platinum–etoposide group, 85 (32%) in the durvalumab plus platinum–etoposide group, and 97 (36%) in the platinum–etoposide group. Treatment-related deaths occurred in 12 (5%) patients in the durvalumab plus tremelimumab plus platinum–etoposide group (death, febrile neutropenia, and pulmonary embolism [n=2 each]; enterocolitis, general physical health deterioration and multiple organ dysfunction syndrome, pneumonia, pneumonitis and hepatitis, respiratory failure, and sudden death [n=1 each]), six (2%) patients in the durvalumab plus platinum–etoposide group (cardiac arrest, dehydration, hepatotoxicity, interstitial lung disease, pancytopenia, and sepsis [n=1 each]), and two (1%) in the platinum–etoposide group (pancytopenia and thrombocytopenia [n=1 each]). Interpretation: First-line durvalumab plus platinum–etoposide showed sustained overall survival improvement versus platinum–etoposide but the addition of tremelimumab to durvalumab plus platinum–etoposide did not significantly improve outcomes versus platinum–etoposide. These results support the use of durvalumab plus platinum–etoposide as a new standard of care for the first-line treatment of ES-SCLC. Funding: AstraZeneca. more...

Background: IDO1 is a mediator of tumor immune suppression through alteration of tryptophan metabolism. Indoximod (1-methyl-tryptophan) is an IDO1 pathway inhibitor. There is preclinical evidence that indoximod acts synergistically with chemotherapy such as taxanes (Uyttenhove, 2003) in an immune dependent fashion. Previous studies demonstrated the safety and activity of indoximod combined with docetaxel in patients with advanced solid tumors, including breast cancer (Soliman, 2014). A phase 2 clinical trial was designed to study the efficacy of indoximod plus taxanes in metastatic breast cancer (MBC) patients (pts). Method: This is a phase II randomized, 1:1 placebo controlled clinical trial, that enrolled MBC pts in multiple centers in the US and Poland. Eligibility criteria included ER+ or ER- HER2- MBC, ability to receive taxane therapy, PS 0-1, normal organ function and absence of autoimmune disease. Pts were randomized to taxane (either weekly paclitaxel 80mg/m2 3 on 1 off or q3wk docetaxel at 75mg/m2 per treating physician’s discretion) + placebo (TP) or taxane + indoximod 1200mg PO BID (TI) as first line treatment for MBC. Primary endpoint was PFS. The sample size of 154 patients was designed to detect a HR of .64 with one sided α=.1 and β=.2 after 95 events. Archival tumor tissue was stained with IHC for IDO1 expression when available. Aperio digital pathology positive pixel algorithm was used for scoring, with manual verification. Median value was used as cut-off for IDO positivity. Results: 164 pts were randomized and treated (85 TI, 79 TP). Demographics and tumor features are shown in table 1. Treatment discontinuation was due to disease progression (60%), adverse events (10%), other (30%). Objective response rate was 40% in TI and 37% in TP arm (p=.74). The median PFS was 6.0 (95% CI, 4.5, 8.1) months in the TI arm and 8.4 (95% CI, 5.6, 9.8) in the TP arm, HR of 1.14 (0.81, 1.60). The median OS was 21.6 months (CI 95%, 16, 39.1) in the TI arm and 21.2 (CI 95%, 19.1, 32.1) in the TP arm. The median follow up was 17.4 (range 0.1, 39.4) months. Grade ≥3 treatment emergent adverse events were observed in 60% of patients in both arms with neutropenia, fatigue, anemia, diarrhea being most common but not significantly different between arms. An exploratory analysis of IDO staining with outcomes in 42 samples (22 in TI and 20 TP) suggested a difference in median PFS in pts with high IDO expression assigned to TI vs. TP (10.3 vs 4 months, p=.047). No other prognostic or predictive associations were observed based on IDO status in the analysis. Conclusions: The combination of indoximod with a taxane in 1st line HER2- MBC was safe and did not result in added toxicity. In an unselected population, no improvement in clinical outcomes was observed for the combination over taxane alone. However, higher tumor IDO expression may select for MBC pts who benefit more from indoximod and should be investigated as a predictive biomarker in future studies.

Background First-line pembrolizumab monotherapy improves overall and progression-free survival in patients with untreated metastatic non-small-cell lung cancer with a programmed death ligand 1 (PD-L1) tumour proportion score (TPS) of 50% or greater. We investigated overall survival after treatment with pembrolizumab monotherapy in patients with a PD-L1 TPS of 1% or greater. Methods This randomised, open-label, phase 3 study was done in 213 medical centres in 32 countries. Eligible patients were adults (≥18 years) with previously untreated locally advanced or metastatic non-small-cell lung cancer without a sensitising EGFR mutation or ALK translocation and with an Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1, life expectancy 3 months or longer, and a PD-L1 TPS of 1% or greater. Randomisation was computer generated, accessed via an interactive voice-response and integrated web-response system, and stratified by region of enrolment (east Asia vs rest of world), ECOG performance status score (0 vs 1), histology (squamous vs non-squamous), and PD-L1 TPS (≥50% vs 1-49%). Enrolled patients were randomly assigned 1:1 in blocks of four per stratum to receive pembrolizumab 200 mg every 3 weeks for up to 35 cycles or the investigator's choice of platinum-based chemotherapy for four to six cycles. Primary endpoints were overall survival in patients with a TPS of 50% or greater, 20% or greater, and 1% or greater (one-sided significance thresholds, p=0·0122, p=0·0120, and p=0·0124, respectively) in the intention-to-treat population, assessed sequentially if the previous findings were significant. This study is registered at ClinicalTrials.gov, number NCT02220894. Findings From Dec 19, 2014, to March 6, 2017, 1274 patients (902 men, 372 women, median age 63 years [IQR 57-69]) with a PD-L1 TPS of 1% or greater were allocated to pembrolizumab (n=637) or chemotherapy (n=637) and included in the intention-to-treat population. 599 (47%) had a TPS of 50% or greater and 818 patients (64%) had a TPS of 20% or greater. As of Feb 26, 2018, median follow-up was 12·8 months. Overall survival was significantly longer in the pembrolizumab group than in the chemotherapy group in all three TPS populations (≥50% hazard ratio 0·69, 95% CI 0·56-0·85, p=0·0003; ≥20% 0·77, 0·64-0·92, p=0·0020, and ≥1% 0·81, 0·71-0·93, p=0·0018). The median surival values by TPS population were 20·0 months (95% CI 15·4-24·9) for pembrolizumab versus 12·2 months (10·4-14·2) for chemotherapy, 17·7 months (15·3-22·1) versus 13·0 months (11·6-15·3), and 16·7 months (13·9-19·7) versus 12·1 months (11·3-13·3), respectively. Treatment-related adverse events of grade 3 or worse occurred in 113 (18%) of 636 treated patients in the pembrolizumab group and in 252 (41%) of 615 in the chemotherapy group and led to death in 13 (2%) and 14 (2%) patients, respectively. Interpretation The benefit-to-risk profile suggests that pembrolizumab monotherapy can be extended as first-line therapy to patients with locally advanced or metastatic non-small-cell lung cancer without sensitising EGFR or ALK alterations and with low PD-L1 TPS.

Anti-programmed death-1 or anti-programmed death-ligand 1 (PD-L1) blockade may be ineffective in some patients with non-small cell lung cancer (NSCLC) with high percentage of tumor cells with PD-L1 expression. In addition, immunotherapy may provide great benefits in patients without PD-L1 expression. The present study assessed PD-L1 protein expression by immunohistochemistry, copy number variation (CNV) of PD-L1 and two single nucleotide polymorphisms (SNPs), rs822335 and rs822336, in the promoter of PD-L1 by quantitative PCR in 673 patients with NSCLC. Overall survival time of patients with NSCLC depending on the assessed predictive factors (PD-L1 CNV or SNP) and the treatment methods (immunotherapy in first/second line of treatment or chemotherapy) was analyzed. The present study revealed significantly higher PD-L1 copies number in patients with ≥10% and ≥50% of tumor cells with PD-L1 expression compared to patients with lower percentage of PD-L1-positive tumor cells (P=0.02 and P=0.0002, respectively). There was a significant positive correlation (R=0.2; P=0.01) between number of PD-L1 copies and percentage of tumor cells with PD-L1 protein expression. Percentage of tumor cells with PD-L1 expression was lower in patients with TT genotype of the rs822335 polymorphism compared to those with CC genotype (P=0.03). The present study observed significantly higher risk of death in patients treated with chemotherapy compared to those treated with immunotherapy (P more...

Background: Necitumumab is a second-generation, recombinant, human immunoglobulin G1 EGFR antibody. In this study, we aimed to compare treatment with necitumumab plus gemcitabine and cisplatin versus gemcitabine and cisplatin alone in patients with previously untreated stage IV squamous non-small-cell lung cancer. Methods: We did this open-label, randomised phase 3 study at 184 investigative sites in 26 countries. Patients aged 18 years or older with histologically or cytologically confirmed stage IV squamous non-small-cell lung cancer, with an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 and adequate organ function and who had not received previous chemotherapy for their disease were eligible for inclusion. Enrolled patients were randomly assigned centrally 1:1 to a maximum of six 3-week cycles of gemcitabine and cisplastin chemotherapy with or without necitumumab according to a block randomisation scheme (block size of four) by a telephone-based interactive voice response system or interactive web response system. Chemotherapy was gemcitabine 1250 mg/m2 administered intravenously over 30 min on days 1 and 8 of a 3-week cycle and cisplatin 75 mg/m2 administered intravenously over 120 min on day 1 of a 3-week cycle. Necitumumab 800 mg, administered intravenously over a minimum of 50 min on days 1 and 8, was continued after the end of chemotherapy until disease progression or intolerable toxic side-effects occurred. Randomisation was stratified by ECOG performance status and geographical region. Neither physicians nor patients were masked to group assignment because of the expected occurrence of acne-like rash-a class effect of EGFR antibodies-that would have unmasked most patients and investigators to treatment. The primary endpoint was overall survival, analysed by intention to treat. We report the final clinical analysis. This study is registered with ClinicalTrials.gov, number NCT00981058. Findings: Between Jan 7, 2010, and Feb 22, 2012, we enrolled 1093 patients and randomly assigned them to receive necitumumab plus gemcitabine and cisplatin (n=545) or gemcitabine and cisplatin (n=548). Overall survival was significantly longer in the necitumumab plus gemcitabine and cisplatin group than in the gemcitabine and cisplatin alone group (median 11·5 months [95% CI 10·4-12·6]) vs 9·9 months [8·9-11·1]; stratified hazard ratio 0·84 [95% CI 0·74-0·96; p=0·01]). In the necitumumab plus gemcitabine and cisplatin group, the number of patients with at least one grade 3 or worse adverse event was higher (388 [72%] of 538 patients) than in the gemcitabine and cisplatin group (333 [62%] of 541), as was the incidence of serious adverse events (257 [48%] of 538 patients vs 203 [38%] of 541). More patients in the necitumumab plus gemcitabine and cisplatin group had grade 3-4 hypomagnesaemia (47 [9%] of 538 patients in the necitumumab plus gemcitabine and cisplatin group vs six [1%] of 541 in the gemcitabine and cisplatin group) and grade 3 rash (20 [4%] vs one [ more...

BACKGROUND: ExteNET showed that 1 year of neratinib, an irreversible pan-HER tyrosine kinase inhibitor, significantly improves 2-year invasive disease-free survival after trastuzumab-based adjuvant therapy in women with HER2-positive breast cancer. We report updated efficacy outcomes from a protocol-defined 5-year follow-up sensitivity analysis and long-term toxicity findings. METHODS: In this ongoing randomised, double-blind, placebo-controlled, phase 3 trial, eligible women aged 18 years or older (≥20 years in Japan) with stage 1-3c (modified to stage 2-3c in February, 2010) operable breast cancer, who had completed neoadjuvant and adjuvant chemotherapy plus trastuzumab with no evidence of disease recurrence or metastatic disease at study entry. Patients who were eligible patients were randomly assigned (1:1) via permuted blocks stratified according to hormone receptor status (hormone receptor-positive vs hormone receptor-negative), nodal status (0 vs 1-3 vs or ≥4 positive nodes), and trastuzumab adjuvant regimen (given sequentially vs concurrently with chemotherapy), then implemented centrally via an interactive voice and web-response system, to receive 1 year of oral neratinib 240 mg/day or matching placebo. Treatment was given continuously for 1 year, unless disease recurrence or new breast cancer, intolerable adverse events, or consent withdrawal occurred. Patients, investigators, and trial funder were masked to treatment allocation. The predefined endpoint of the 5-year analysis was invasive disease-free survival, analysed by intention to treat. ExteNET is registered with ClinicalTrials.gov, number NCT00878709, and is closed to new participants. FINDINGS: Between July 9, 2009, and Oct 24, 2011, 2840 eligible women with early HER2-positive breast cancer were recruited from community-based and academic institutions in 40 countries and randomly assigned to receive neratinib (n=1420) or placebo (n=1420). After a median follow-up of 5·2 years (IQR 2·1-5·3), patients in the neratinib group had significantly fewer invasive disease-free survival events than those in the placebo group (116 vs 163 events; stratified hazard ratio 0·73, 95% CI 0·57-0·92, p=0·0083). The 5-year invasive disease-free survival was 90·2% (95% CI 88·3-91·8) in the neratinib group and 87·7% (85·7-89·4) in the placebo group. Without diarrhoea prophylaxis, the most common grade 3-4 adverse events in the neratinib group, compared with the placebo group, were diarrhoea (561 [40%] grade 3 and one [BACKGROUND: ExteNET showed that 1 year of neratinib, an irreversible pan-HER tyrosine kinase inhibitor, significantly improves 2-year invasive disease-free survival after trastuzumab-based adjuvant therapy in women with HER2-positive breast cancer.

Background: Afatinib has demonstrated clinical benefit in patients with non-small-cell lung cancer progressing after treatment with erlotinib/gefitinib. This phase III trial prospectively assessed whether continued irreversible ErbB-family blockade with afatinib plus paclitaxel has superior outcomes versus switching to chemotherapy alone in patients acquiring resistance to erlotinib/gefitinib and afatinib monotherapy. Patients and methods: Patients with relapsed/refractory disease following ≥ 1 line of chemotherapy, and whose tumors had progressed following initial disease control (≥ 12 weeks) with erlotinib/gefitinib and thereafter afatinib (50 mg/day), were randomized 2:1 to receive afatinib plus paclitaxel (40 mg/day; 80 mg/m2/week) or investigator's choice of single-agent chemotherapy. The primary end point was progression-free survival (PFS). Other end points included objective response rate (ORR), overall survival (OS), safety and patient-reported outcomes. Results: Two hundred and two patients with progressive disease following clinical benefit from afatinib were randomized to afatinib plus paclitaxel (n ≥ 134) or single-agent chemotherapy (n ≥ 68). PFS (median 5.6 versus 2.8 months, hazard ratio 0.60, P ≥ 0.003) and ORR (32.1% versus 13.2%, P ≥ 0.005) significantly improved with afatinib plus paclitaxel. There was no difference in OS. Global health status/quality of life was maintained with afatinib plus paclitaxel over the entire treatment period. The median treatment duration was 133 and 51 days with afatinib plus paclitaxel and single-agent chemotherapy, respectively; 48.5% of patients receiving afatinib plus paclitaxel and 30.0% of patients receiving single-agent chemotherapy experienced drug-related grade 3/4 adverse events. Treatment-related adverse events were consistent with those previously reported with each agent. Conclusion: Afatinib plus paclitaxel improved PFS and ORR compared with single-agent chemotherapy in patients who acquired resistance to erlotinib/gefitinib and progressed on afatinib after initial benefit. LUX-Lung 5 is the first prospective trial to demonstrate the benefit of continued ErbB targeting post-progression, versus switching to single-agent chemotherapy.

Necitumumab is a second-generation recombinant human immunoglobulin G1 EGFR monoclonal antibody that competitively inhibits ligand binding. We aimed to compare necitumumab plus pemetrexed and cisplatin with pemetrexed and cisplatin alone in patients with previously untreated, stage IV, non-squamous non-small-cell lung cancer (NSCLC).We did this randomised, open-label, controlled phase 3 study at 103 sites in 20 countries. Patients aged 18 years or older, with an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 and adequate organ function, were randomly assigned 1:1 to treatment with a block randomisation scheme (block size of four) via a telephone-based interactive voice-response system or interactive web-response system. Patients received either cisplatin 75 mg/m(2) and pemetrexed 500 mg/m(2) on day 1 of a 3-week cycle for a maximum of six cycles alone, or with necitumumab 800 mg on days 1 and 8. Necitumumab was continued after the end of chemotherapy until disease progression or unacceptable toxic effects. Randomisation was stratified by smoking history, ECOG performance status, disease histology, and geographical region. Patients and study investigators were not masked to group assignment. The primary endpoint was overall survival. Efficacy analyses were by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00982111.Between Nov 11, 2009, and Feb 2, 2011, we randomly assigned 633 patients to receive either necitumumab plus pemetrexed and cisplatin (n=315) or pemetrexed and cisplatin alone (n=318). Enrolment was stopped on Feb 2, 2011, after a recommendation from the independent data monitoring committee. There was no significant difference in overall survival between treatment groups, with a median overall survival of 11·3 months (95% CI 9·5-13·4) in the necitumumab plus pemetrexed and cisplatin group versus 11·5 months (10·1-13·1) in the pemetrexed and cisplatin group (hazard ratio 1·01 [95% CI 0·84-1·21]; p=0·96). The incidence of grade 3 or worse adverse events, including deaths, was higher in the necitumumab plus pemetrexed and cisplatin group than in the pemetrexed and cisplatin group; in particular, deaths regarded as related to study drug were reported in 15 (5%) of 304 patients in the necitumumab group versus nine (3%) of 312 patients in the pemetrexed and cisplatin group. Serious adverse events were likewise more frequent in the necitumumab plus pemetrexed and cisplatin group than in the pemetrexed and cisplatin group (155 [51%] of 304 vs 127 [41%] of 312 patients). Patients in the necitumumab plus pemetrexed and cisplatin group had more grade 3-4 rash (45 [15%] of 304 vs one [1%] of 312 patients in the pemetrexed and cisplatin alone group), hypomagnesaemia (23 [8%] vs seven [2%] patients), and grade 3 or higher venous thromboembolic events (23 [8%] vs 11 [4%] patients) than did those in the pemetrexed and cisplatin alone group.Our findings show no evidence to suggest that the addition of necitumumab to pemetrexed and cisplatin increases survival of previously untreated patients with stage IV non-squamous NSCLC. Unless future studies identify potentially useful predictive biomarkers, necitumumab is unlikely to provide benefit in this patient population when combined with pemetrexed and cisplatin.Eli Lilly and Company. more...

Meeting abstracts TG4010 is an immunotherapy using an attenuated and modified poxvirus (MVA) coding for MUC1 and interleukin-2 to induce a cellular immune response against MUC1 expressing tumors.

Aim: TG4010 immunotherapy product is a poxvirus (MVA) coding for MUC1 tumor-associated antigen and interleukin-2. A previous study showed that a normal baseline level of Triple Positive Activated Lymphocytes (TrPAL, CD16 + CD56 + CD69+) might be a predictive biomarker for TG4010 efficacy in NSCLC (Lancet Oncol 2011;12:1125-33). TIME is a double-blind phase 2b/3 study (NCT01383148) comparing the combination of first line therapy with TG4010 or placebo. The Phase 2b part aims at prospectively validating the baseline TrPAL level as a predictive biomarker. Methods: Primary endpoint of the Phase 2b part of the study was to compare progression-free survival (PFS, according to RECIST 1.1) between TG4010 and placebo arms using a Bayesian design, in stage IV NSCLC patients with a MUC1+ tumor. Secondary objectives were response rate, safety, survival and subgroup analyses. A dynamic minimization procedure was applied at randomization for histology, prescription of bevacizumab, type of chemotherapy, performance status and center. Results: 217 patients have been enrolled out of which 170 patients with a normal TrPAL level (pre-determined threshold) and an analysis of PFS was conducted in this cohort after 137 events of progression were recorded. The hazard ratio (HR) for PFS is 0.76 (95%CI: 0.54-1.06). This corresponds to a 97.5% Bayesian probability that the true HR is Conclusions: These data support the predictive value of the TrPAL biomarker. They also confirm TG4010 efficacy and safety profile in stage IV NSCLC patients and warrant the continuation of the TIME study with its Phase 3 part. Disclosure: E.

Alectinib, a highly selective inhibitor of anaplastic lymphoma kinase (ALK), has shown systemic and central nervous system (CNS) efficacy in the treatment of ALK-positive non-small-cell lung cancer (NSCLC). We investigated alectinib as compared with crizotinib in patients with previously untreated, advanced ALK-positive NSCLC, including those with asymptomatic CNS disease. In a randomized, open-label, phase 3 trial, we randomly assigned 303 patients with previously untreated, advanced ALK-positive NSCLC to receive either alectinib (600 mg twice daily) or crizotinib (250 mg twice daily). The primary end point was investigator-assessed progression-free survival. Secondary end points were independent review committee-assessed progression-free survival, time to CNS progression, objective response rate, and overall survival. During a median follow-up of 17.6 months (crizotinib) and 18.6 months (alectinib), an event of disease progression or death occurred in 62 of 152 patients (41%) in the alectinib group and 102 of 151 patients (68%) in the crizotinib group. The rate of investigator-assessed progression-free survival was significantly higher with alectinib than with crizotinib (12-month event-free survival rate, 68.4% [95% confidence interval (CI), 61.0 to 75.9] with alectinib vs. 48.7% [95% CI, 40.4 to 56.9] with crizotinib; hazard ratio for disease progression or death, 0.47 [95% CI, 0.34 to 0.65]; P more...
