Cancer treatments that couple pharmacological activation of tumor antigen presentation with activation and expansion of CD8+ T and natural killer (NK) cells in the tumor environment have the potential to induce an effective anti-tumor immune response in patients. NKTR-262 is a small molecule agonist of toll-like receptors (TLRs) 7/8 designed to be retained in the tumor micro-environment in order to activate antigen-presenting cells (APC), such as dendritic cells, to create new antigen-specific cytotoxic T cells. As a CD122-biased agonist, bempegaldesleukin monotherapy increases newly proliferative CD8+ T cells in tumors. NKTR-262 plus bempegaldesleukin is expected to increase expansion of antigen-specific CD8+ T cells. In preclinical studies, a single IT injection of NKTR-262 plus IV bempegaldesleukin resulted in complete abscopal effects in tumor models. Preliminary clinical data show bempegaldesleukin plus nivolumab enhances immune-stimulatory responses. The REVEAL trial will assess safety and anti-tumor activity of NKTR-262 with bempegaldesleukin +/- nivolumab for the treatment of selected cancers.

Experimental: NKTR-262 + bempegaldesleukin or + bempegaldesleukin with nivolumab
Phase 1: NKTR-262 in escalating doses, combined with bempegaldesleukin. The goal of this dose escalation part of the study is to establish a recommended Phase 1b dose for NKTR-262 + bempegaldesleukin with nivolumab, followed by a dose-confirmation cohort.
|
Drug: NKTR-262
During Phase 1 Doublet: Patients receive escalating doses of NKTR-262 IT (starting dose 0.03 mg) in 3-week treatment cycles. During Phase 1 Doublet (Cohort A), Phase 2 Doublet: Patients were to receive the RP2D of NKTR-262. During Phase 1 Triplet (Cohort B), and Phase 2 Triplet: Patients receive the RP2D of NKTR-262. Drug: bempegaldesleukin During Phase 1 Doublet (Cohort A), and proposed Phase 2 Doublet: Patients receive 0.006 mg/kg bempegaldesleukin administered in 3-week treatment cycles. During Phase 1 Triplet (Cohort B), and proposed Phase 2 Triplet: Patients receive 0.006 mg/kg bempegaldesleukin administered in 3-week treatment cycles. Other Name: NKTR-214 Drug: nivolumab During Phase 1 Triplet (Cohort B), and proposed Phase 2 Triplet: Patients receive a nivolumab flat dose of 360 mg administered in 3-week treatment cycles.
Other Name: Opdivo® |
- Number of Participants Experiencing Dose-Limiting Toxicities (DLTS) [ Time Frame: The DLT window is 21 days following NKTR-262 single agent administration (Cycle 1) and an additional 9 days when combined with bempeg for staggered dosing administration (Cohorts 1 and 2), or 7 days for the same day administration (Cohort 3 and higher). ]
DLTs were assessed in Cohort 1 through Cohort 9, which had dose levels of NKTR-262 as 0.03mg, 0.06mg, 0.06mg, 0.12mg, 0.24mg, 0.48mg, 0.96mg, 1.92mg, and 3.84mg in combination with bempegaldesleukin (bempeg).
There was only 1 DLT that occurred in one of the Cohort 9 patients. Therefore, the maximum tolerated dose (MTD) of NKTR 262 was not reached.
- Objective Response Rate (ORR) Per RECIST 1.1 in Cohort A and Cohort B at Recommended Phase 2 Dose (RP2D) [ Time Frame: From Cycle 1 Day 1 to 100 days after the last dose of study drug or the date for new anti-cancer therapy, whichever is earlier. ]
Objective Response Rate (ORR) per RECIST 1.1 in Cohort A and Cohort B at Recommended Phase 2 Dose (RP2D).
ORR is defined as the percentage of subjects with evidence of a confirmed complete response (CR) or partial response (PR) as per Response Evaluation Criteria In Solid Tumors (RECIST) Version 1.1 and as assessed by Blinded Independent Central Review (BICR).
