Abstract Disclosures


Background: Standard of care for pts with previously untreated, unresectable or metastatic MEL includes checkpoint inhibitors. Bempegaldesleukin is a CD122-preferential IL-2 pathway agonist designed to provide sustained signaling through the IL-2 βγ receptor to activate and proliferate effector CD8+ T and NK cells over T-regulatory cells in the tumor (Hurwitz ME et al. ASCO GU 2017). In the dose-expansion phase of the phase 1/2 PIVOT-02 trial, bempegaldesleukin + NIVO was well tolerated at the recommended phase 2 dose (RP2D; bempegaldesleukin 0.006 mg/kg IV Q3W + NIVO 360 mg IV Q3W), and previously untreated pts with MEL receiving the RP2D achieved an objective response rate (ORR) of 20/38 (53%) and a complete response of 9/38 (24%) by independent radiology review (Diab A et al. SITC 2018). Presented is the design of the first phase 3 trial in the bempegaldesleukin + NIVO development program in pts with previously untreated, unresectable or metastatic MEL. Methods: This phase 3, randomized, open-label study aims to evaluate the effectiveness, safety, and tolerability of bempegaldesleukin + NIVO (NCT03635983). Eligible pts are ≥12 y with histologically confirmed stage III (unresectable) or stage IV MEL and ECOG PS ≤1 or Lansky PS ≥80% (minors 12-17 y). Pts are ineligible if they have active brain or leptomeningeal metastases, uveal MEL, or a recurrence within 6 mo of completing adjuvant treatment with any approved agent. Pts will be stratified by PD-L1 status (measured using PD-L1 IHC 28-8 pharmDx), BRAF mutation status, and lactate dehydrogenase level, and will be randomized to receive bempegaldesleukin 0.006 mg/kg IV Q3W + NIVO 360 mg IV Q3W or NIVO 360 mg IV Q3W up to 24 mo, or until progression or unacceptable toxicity (N ~ 764). Primary endpoints are ORR and progression-free survival (PFS) by blinded independent central review (BICR) and overall survival (OS). Secondary endpoints include ORR and PFS by investigator, ORR and PFS by BICR in biomarker population, OS in biomarker population, and safety. Additional endpoints include pharmacokinetics and quality-of-life assessment. Clinical trial information: NCT03635983
