Brief Title: A Dose Escalation and Cohort Expansion Study of NKTR-214 in Combination With Nivolumab and Other Anti-Cancer Therapies in Patients With Select Advanced Solid Tumors ( PIVOT-02 )

A Phase 1/2, Open-label, Multicenter Study of the Combination of NKTR-214 and Nivolumab or the Combination of NKTR-214, Nivolumab, and Other Anti-Cancer Therapies in Patients With Select Locally Advanced or Metastatic Solid Tumor Malignancies

INTRODUCTION

  • Org Study ID: 16-214-02
  • Secondary ID: N/A
  • NCT ID: NCT02983045
  • Sponsor: Nektar Therapeutics

BRIEF SUMMARY

In this four-part study, NKTR-214 was administered in combination with nivolumab and with/without other anticancer therapies. Part 1 considered escalating doublet (NKTR 214 + nivolumab) doses to determine the RP2D. Part 2 considered dose expansion cohorts for the doublet (NKTR 214 + nivolumab ± chemotherapy). Part 3 was schedule-finding for a triplet therapy (NKTR 214 + nivolumab + ipilimumab). Part 4 dose expansion for the triplet (NKTR 214 + nivolumab + ipilimumab) was planned to further assess the efficacy of the RP2D triplet combination at dosing schedules from Part 3.

DETAILED DESCRIPTION

Part 1 enrolled patients with advanced or metastatic melanoma, renal cell carcinoma (RCC), non-small cell lung cancer (NSCLC), urothelial carcinoma, or triple negative breast cancer (TNBC) to determine the recommended Phase 2 dose (RP2D) or maximum tolerated dose (MTD) of NKTR 214 + nivolumab doublet therapy.

Part 2 enrolled patients with advanced or metastatic solid tumor malignancies (including 9 tumor types consisting of the same 5 tumor types as in Part 1, plus hormone receptor positive human epidermal growth factor receptor 2 [HER 2] negative breast cancer [HR+ HER2- BC], gastric cancer, colorectal carcinoma, and small cell lung cancer [SCLC]) to assess the efficacy of the RP2D.

Part 3 enrolled patients with advanced or metastatic melanoma, RCC, NSCLC, or urothelial carcinoma (UCC) in a first-line setting (1L) to assess the safety and tolerability of NKTR 214 + nivolumab + ipilimumab triplet therapy Three dosing schedules were evaluated to establish RP2D dosing schedules for Part 4 of the study.

Part 4 planned to enroll patients with advanced or metastatic melanoma, RCC, NSCLC, or UCC to further assess the efficacy of the RP2D triplet combination at the 3 dosing schedules from Part 3. Patients were enrolled simultaneously to each tumor cohort.

All patients enrolled in the study were closely monitored for safety, tolerability and response per RECIST criteria. The primary efficacy endpoint was objective response rate (ORR) using RECIST 1.1 at the RP2D doublet.
