Despite recent changes in the treatment landscape, there remains an unmet need for effective, tolerable, chemotherapy-free treatments for patients with advanced/metastatic urothelial carcinoma (mUC), especially cisplatin-ineligible patients.To evaluate the immunostimulatory interleukin-2 cytokine prodrug bempegaldesleukin (BEMPEG) plus nivolumab in patients with advanced/mUC from the phase 2 multicenter PIVOT-02 study.This open-label, multicohort phase 1/2 study enrolled patients with previously untreated locally advanced/surgically unresectable or mUC (N = 41).Patients received BEMPEG 0.006 mg/kg plus nivolumab 360 mg intravenously every 3 wk.The primary objectives were safety and the objective response rate (ORR) in patients with measurable disease at baseline and at least one postbaseline tumor response assessment (response-evaluable). Secondary objectives were overall survival (OS) and progression-free survival (PFS). Exploratory biomarker analyses via univariate logistic regression were performed to test the association between potential biomarkers (CD8The ORR was 35% (13/37 evaluable patients) and the complete response rate was 19% (7/37 patients); the median duration of response was not reached. Median PFS was 4.1 mo (95% confidence interval [CI] 2.1-8.7) and median OS was 23.7 mo (95% CI 15.8-not reached). Overall, 40/41 patients (98%) experienced at least one treatment-related adverse event (TRAE); grade 3/4 TRAEs occurred in 11 patients (27%), most commonly pyrexia (4.9%; 2 patients). Exploratory biomarker analyses showed no association between biomarkers and response. Limitations include the small sample size and single-arm design.BEMPEG plus nivolumab was well tolerated and showed antitumor activity as first-line treatment in patients with locally advanced/mUC.We investigated an immune-stimulating prodrug called bempegaldesleukin plus the antibody nivolumab as the first therapy for patients with advanced or metastatic cancer of the urinary tract. This combination had manageable treatment-related side effects and was effective in a subset of patients. This trial is registered at ClinicalTrials.gov as NCT02983045.

- Abstract
This single-arm, phase I dose-escalation trial (NCT02983045) evaluated bempegaldesleukin (NKTR-214/BEMPEG), a CD122-preferential IL2 pathway agonist, plus nivolumab in 38 patients with selected immunotherapy-naïve advanced solid tumors (melanoma, renal cell carcinoma, and non–small cell lung cancer). Three dose-limiting toxicities were reported in 2 of 17 patients during dose escalation [hypotension (n = 1), hyperglycemia (n = 1), metabolic acidosis (n = 1)]. The most common treatment-related adverse events (TRAE) were flu-like symptoms (86.8%), rash (78.9%), fatigue (73.7%), and pruritus (52.6%). Eight patients (21.1%) experienced grade 3/4 TRAEs; there were no treatment-related deaths. Total objective response rate across tumor types and dose cohorts was 59.5% (22/37), with 7 complete responses (18.9%). Cellular and gene expression analysis of longitudinal tumor biopsies revealed increased infiltration, activation, and cytotoxicity of CD8+ T cells, without regulatory T-cell enhancement. At the recommended phase II dose, BEMPEG 0.006 mg/kg plus nivolumab 360 mg every 3 weeks, the combination was well tolerated and demonstrated encouraging clinical activity irrespective of baseline PD-L1 status.Significance:These data show that BEMPEG can be successfully combined with a checkpoint inhibitor as dual immunotherapy for a range of advanced solid tumors. Efficacy was observed regardless of baseline PD-L1 status and baseline levels of tumor-infiltrating lymphocytes, suggesting therapeutic potential for patients with poor prognostic risk factors for response to PD-1/PD-L1 blockade.See related commentary by Rouanne et al., p. 1097.This article is highlighted in the In This Issue feature, p. 1079

- Abstract
NKTR-214 (bempegaldesleukin) is a novel IL2 pathway agonist, designed to provide sustained signaling through heterodimeric IL2 receptor βγ to drive increased proliferation and activation of CD8+ T and natural killer cells without unwanted expansion of T regulatory cells (Treg) in the tumor microenvironment. In this first-in-human multicenter phase I study, NKTR-214 administered as an outpatient regimen was well tolerated and showed clinical activity including tumor shrinkage and durable disease stabilization in heavily pretreated patients. Immune activation and increased numbers of immune cells were observed in the periphery across all doses and cycles with no loss of NKTR-214 activity with repeated administration. On-treatment tumor biopsies demonstrated that NKTR-214 promoted immune cell increase with limited increase of Tregs. Transcriptional analysis of tumor biopsies showed that NKTR-214 engaged the IL2 receptor pathway and significantly increased genes associated with an effector phenotype. Based on safety and pharmacodynamic markers, the recommended phase II dose was determined to be 0.006 mg/kg every three weeks.Significance:We believe that IL2- and IL2 pathway–targeted agents such as NKTR-214 are key components to an optimal immunotherapy treatment algorithm. Based on its biological activity and tolerability, NKTR-214 is being studied with approved immuno-oncology agents including checkpoint inhibitors.See related commentary by Sullivan, p. 694.This article is highlighted in the In This Issue feature, p. 681

BackgroundImmune checkpoint inhibitor-based combinations have expanded the treatment options for patients with renal cell carcinoma (RCC); however, tolerability remains challenging. The aim of this study was to evaluate the safety and efficacy of the immunostimulatory interleukin-2 cytokine prodrug bempegaldesleukin (BEMPEG) plus nivolumab (NIVO) as first-line therapy in patients with advanced clear-cell RCC.MethodsThis was an open-label multicohort, multicenter, single-arm phase 1/2 study; here, we report results from the phase 1/2 first-line RCC cohort (N=49). Patients received BEMPEG 0.006 mg/kg plus NIVO 360 mg intravenously every 3 weeks. The primary objectives were safety and objective response rate (ORR; patients with measurable disease at baseline and at least one postbaseline tumor response assessment). Secondary objectives included overall survival (OS) and progression-free survival (PFS). Exploratory biomarker analyses: association between baseline biomarkers and ORR.ResultsAt a median follow-up of 32.7 months, the ORR was 34.7% (17/49 patients); 3/49 patients (6.1%) had a complete response. Of the 17 patients with response, 14 remained in response for >6 months, and 6 remained in response for >24 months. Median PFS was 7.7 months (95% CI 3.8 to 13.9), and median OS was not reached (95% CI 37.3 to not reached). Ninety-eight per cent (48/49) of patients experienced ≥1 treatment-related adverse event (TRAE) and 38.8% (19/49) had grade 3/4 TRAEs, most commonly syncope (8.2%; 4/49) and increased lipase (6.1%; 3/49). No association between exploratory biomarkers and ORR was observed. Limitations include the small sample size and single-arm design.ConclusionsBEMPEG plus NIVO showed preliminary antitumor activity as first-line therapy in patients with advanced clear-cell RCC and was well tolerated. These findings warrant further investigation.

Bempegaldesleukin (BEMPEG: NKTR-214) is an immunostimulatory IL-2 cytokine prodrug engineered to deliver a controlled, sustained and preferential IL-2 pathway signal. Nivolumab (NIVO), a PD-1 inhibitor, has been shown to prolong survival in patients with advanced melanoma and recurrence-free survival in the adjuvant setting. PIVOT-02 showed that BEMPEG plus NIVO was well-tolerated and demonstrated clinical activity as first-line therapy in metastatic melanoma. PIVOT-12 is a randomized, phase III, global, multicenter, open-label study comparing adjuvant therapy with BEMPEG plus NIVO versus NIVO alone in adult and adolescent patients with completely resected cutaneous stage III/IV melanoma at high risk of recurrence. The primary objective is to compare the efficacy, as measured by recurrence-free survival, of BEMPEG plus NIVO versus NIVO. Following surgery, patients with advanced melanoma may require further treatment to reduce the likelihood of disease recurrence. Nivolumab (NIVO), a checkpoint inhibitor, reduces the risk of melanoma recurrence by enhancing the ability of the immune system to fight disease. Despite the availability of NIVO and other therapies, many patients with melanoma still experience disease recurrence after surgery. This article presents information on a clinical trial named PIVOT-12, which aims to assess the effectiveness of a new investigational drug called bempegaldesleukin that modifies the immune system and is given with NIVO to patients with stage III/IV melanoma following surgery. The main end point being measured is recurrence-free survival, which measures the time between a patient starting the study and the date of disease recurrence. Clinical Trial Registration: NCT04410445 (ClinicalTrials.gov).

Introduction: NKTR-255, an investigational novel polymer-conjugated recombinant human interleukin (IL)-15 agonist, maintains the full spectrum of IL-15 biology and provides sustained pharmacodynamic (PD) responses without the need for daily dosing. NKTR-255 engages IL-15Rα and IL-2/IL-15Rβγ leading to natural killer (NK) and CD8 + T-cell expansion, proliferation, and activation. In preclinical studies, NKTR-255 enhanced antibody-dependent cellular cytotoxicity (ADCC) of each of daratumumab, rituximab, trastuzumab, and cetuximab, resulting in synergistic anticancer activity. This ongoing Phase 1 trial (NCT04136756) evaluates the safety, tolerability, and pharmacokinetic (PK)/PD of NKTR-255 in patients with hematologic malignancies, including determination of the recommended Phase 2 dose (RP2D). Methods: Heavily pretreated patients with relapsed/refractory multiple myeloma (MM) or non-Hodgkin lymphoma (NHL) received escalating doses of NKTR-255 intravenously every 3 weeks. Patients were observed following the first NKTR-255 dose for dose-limiting toxicity. Preliminary PK and PD analyses were conducted. NKTR-255-mediated activation of the immune system was assessed by flow cytometry and plasma cytokine analysis. Fold change was calculated as treatment with NKTR-255 over baseline (baseline = 1). Results: As of June 8, 2021, 14 patients were enrolled, ranging in age from 49 to 80 years; 71% male. Eight (57%) had MM and 6 (43%) had NHL. Two (25%) of 8 patients with MM and 2 (33%) of 6 patients with NHL had received prior chimeric antigen receptor T-cell (CAR-T) therapy. The 14 patients were dosed at 4 levels: (1.5 µg/kg: 3 patients; 3.0 µg/kg: 4 patients; 4.5 µg/kg: 4 patients; 6.0 µg/kg: 3 patients). Among the 11 response-evaluable patients, 7 patients (64%) reported disease stabilization (4/5 [80%] MM patients; 3/6 [50%] NHL patients). Treatment-related adverse events occurring in ≥30% of patients were pyrexia (12/14; 86%), chills (10/14; 71%), nausea (8/14; 57%), headache (6/14; 43%), infusion-related reaction (5/14; 36%), and fatigue (5/14; 36%). Most adverse events were transient and resolved spontaneously, or by using standard treatment protocols. No dose-limiting toxicities were observed, and no patients discontinued NKTR-255 due to adverse events. NKTR-255- induced dose dependent, transient changes in inflammatory cytokines, including interferon-γ, monocyte chemoattractant protein-1 and IL-6 peaked at 3 to 6 hours post-infusion and resolved to baseline levels by 24 to 48 hours, supporting the safety profile of NKTR-255. Preliminary PK analyses showed target mediate disposition at the lowest dose level (1.5 µg/kg) and linear PK toward higher dose levels (>3.0 µg/kg). The average half-life of NKTR-255 was ~39 hours. No accumulation was observed following repeat dosing. There was a dose-dependent expansion in cell numbers of NK and CD8+ T cells in the peripheral blood of patients, with peak fold-changes of ~8-fold and ~2-fold respectively, within the first 2 cycles of NKTR-255 treatment at the 6.0 µg/kg dose. Consistent with NKTR-255 mechanism of action, minimal induction of Tregs was observed at all dose levels tested. Moreover, NK and CD8 + T cells demonstrated proliferative ability, which was maintained across multiple treatment cycles at all dose levels. Conclusions: In this heavily pretreated relapsed/refractory patient population with hematologic malignancies, NKTR-255 was biologically active, and demonstrated sustained increases in NK and CD8 + T cells. NKTR-255 was well tolerated with minimal treatment-related toxicities and transient upregulation and rapid decline of cytokines to baseline levels. RP2D for NKTR-255 monotherapy has not yet been reached; and dose escalation is ongoing at 9.0 µg/kg. NKTR-255 is currently being evaluated in multiple clinical studies in both hematologic malignancies and solid tumors as a monotherapy and in combination with agents that induce ADCC. Ethics approval: The study was approved by the institutional review board of each participating site.

3006Background: PIVOT is an ongoing, open-label, phase 1/2 study of NKTR-214 (214; CD122-biased agonist) plus PD-1 inhibitor nivolumab (N) in patients (pts) with advanced cancers (MEL, RCC, NSCLC, TNBC, and UC). 214 monotherapy increases newly proliferative CD8+ T cells in tumors and increases cell surface PD-1 and PD-L1 expression, demonstrating a potentially synergistic mechanism with anti-PD-1 therapy. Methods: In P1 dose escalation, pts received 214 (0.003, 0.006 or 0.009 mg/kg) with N (240 mg or 360 mg) administered IV as outpatient Q2W or Q3W; in P2 expansion, the RP2D of 214 (0.006 mg/kg) with N (360 mg) Q3W was administered concurrently. Response was assessed Q8W by RECIST v1.1. Matched tumor samples were evaluated for changes from baseline in immune cell populations, gene expression, and T cell receptor repertoire. Tumor baseline and on treatment PD-L1 protein expression was assessed (28-8 IHC assay). Results: As of 7FEB2018, 162 pts (P1, n = 38; P2, n = 124) were evaluable for safety. The most c...
