Abstract 4403


Significant advancements, including development of immune checkpoint inhibitors and targeted therapies, have transformed outcomes for patients (pts) with unresectable or metastatic melanoma. However, pts who do not respond or who progress while receiving these regimens have limited options. Spartalizumab (PDR001) is a high-affinity, humanized monoclonal antibody blocking the programmed cell death 1 (PD-1) receptor. This study is evaluating combinations of spartalizumab with novel compounds to restore antitumor T-cell activity in pts with melanoma progressing after prior PD-1 blockade therapy.

Trial design

This randomized, open-label, 2-part, multicenter, open platform, phase II study (NCT03484923; PLATforM) will evaluate safety and efficacy of spartalizumab combination treatment in pts with unresectable or metastatic melanoma progressing after prior anti–PD-1/L1 therapy and a BRAF inhibitor if the tumor harbors a BRAF V600 mutation. The primary endpoint will be objective response rate per RECIST v1.1, with duration of response and assessment of paired tumor biopsies for biomarkers of antitumor T-cell activity as part of the secondary endpoints. The first “selection” part of the study will begin with 3 combination arms: (1) spartalizumab + LAG525 (LAG-3 antibody), (2) spartalizumab + capmatinib (c-MET inhibitor), and (3) spartalizumab + canakinumab (IL-1β antagonist). For the selection part, the PLATforM study uses an adaptive design that, during the selection phase, allows dropping arms for futility, adding new arms, and selecting 1 or multiple arms for further expansion. Bayesian methodology is used with specific probability criteria for futility and efficacy assessments at each interim analysis. Pts (≈ 60-85) will be stratified by baseline lactate dehydrogenase level and randomized equally to all open arms during the selection part. In the second “expansion” part, efficacy and safety of treatment combination(s) selected during part one will be further investigated. Sample size for part two will be adaptive and based on predictive power calculations considering the results from the selection part.
