NKTR-102 Versus Irinotecan in Patients With Second-Line, Irinotecan-Naïve, KRAS Mutant, Colorectal Cancer

ABSTRACT: This study will evaluate whether NKTR-102, an investigational drug has an anti-tumor effect in patients with colorectal cancer. This study will also evaluate how the safety and anti-tumor activity of NKTR-102 compares with irinotecan, a cancer drug that is approved for use in the US for treatment of patients with certain types of colorectal cancer.

Project description:Primary objectives: To estimate the progression-free survival (PFS) with NKTR-102 versus irinotecan. Primary endpoints: The primary endpoint of this study is progression-free survival (PFS), which is defined as the time from the date of randomization to the date of progressive disease (PD), death due to any cause, premature removal from the study due to unacceptable toxicity or the initiation of new therapy.

NKTR-102 in Combination With Cetuximab in Patients With Refractory Solid Tumors (Phase 2a) and Metastatic or Locally Advanced Colorectal Cancer (Phase 2b)

Project description:Study 07-PIR-02 is a Phase 2 study designed to evaluate the safety and efficacy of NKTR-102 (PEG-irinotecan) for the treatment of patients with colorectal cancer (CRC). The study is comprised of two sequential components - Phase 2a and Phase 2b. The Phase 2a portion is an open-label, dose-finding trial in multiple solid tumor types that are refractory to standard curative or palliative therapies. The primary endpoint of the Phase 2a is to establish the /recommended Phase 2 Dose (RPTD) of NKTR-102 by measuring the frequency of Dose Limiting Toxicity (DLT). The Phase 2b portion is an open-label, randomized, two-arm study in patients with second-line metastatic colorectal cancer and study participants will be randomized (1:1) to receive either NKTR-102 and cetuximab or irinotecan and cetuximab. The primary endpoint of the Phase 2b portion of the trial is progression-free survival. Secondary endpoints for both the Phase 2a and 2b portion include response rate, response duration, overall survival, standard pharmacokinetics, and incidence of toxicities, including diarrhea and neutropenia.

Improved expansion, functionality and tumor targeting of adoptively transferred T cells with kinetically engineered IL-2

Project description:The adoptive transfer of cancer-specific T cells in combination with high dose interleukin-2 (IL-2) is able to induce effective anti-tumor responses. However, tumors frequently relapse after an initial response and the known toxicities of IL-2 further limit the use of this therapy. NKTR-214 is a CD122-biased polyethylene glycol (PEG)-genetically engineered IL-2 designed to provide sustained signaling through the heterodimeric IL-2 receptor pathway (IL-2Rβγ) to preferentially activate and expand CD8 T and natural killer (NK) cells over T regulatory cells (Tregs) in the tumor. We report that combination of adoptive T cell transfer (ACT) and NKTR-214 markedly increases the proliferation, homing and polyfunctionality of antitumor T cells into the tumor. The treatment is well tolerated and leads to robust anti-tumor response in the aggressive B16F10 model. These results suggest that NKTR-214 could improve the efficacy of ACT protocols tested in humans.

Study of NKTR 255 in Combination With Cetuximab in Solid Tumors

Project description:This is a Phase 1b/2, open-label multicenter study evaluating NKTR-255 as a monotherapy and together with cetuximab in patients with head and neck squamous cell carcinoma (HNSCC), colorectal carcinoma (CRC), cutaneous squamous cell carcinoma (cSCC), anal cell carcinoma (ASCC) and cervical cancer. The recommended phase 2 dose of NKTR-255, determined in the dose escalation phase (Phase 1b), will be used to treat patients in Phase 2 of this study.

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

Project description: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.

TAS-102, Irinotecan, and Bevacizumab in Pre-treated Metastatic Colorectal Cancer (TABAsCO), A Phase II Clinical Trial. ClinicalTrials.gov NCT04109924

Project description:Background: The efficacy of FOLFIRI plus an antiangiogenesis biologic agent as 2nd line therapy for metastatic colorectal adenocarcinoma is limited. TAS-102 is a novel oral antimetabolite with a distinct mechanism of action from fluoropyrimidines. We evaluated the antitumor efficacy of TAS-102, irinotecan and bevacizumab in patients with pre-treated, advanced colorectal adenocarcinoma in a multicenter, phase II, single-arm study. Methods: Patients with advanced colorectal adenocarcinoma who had progressed after oxaliplatin and fluoropyrimidine and were eligible for treatment with bevacizumab were treated with irinotecan, bevacizumab, and TAS-102 in 28-day cycles. The primary endpoint was progression-free survival (PFS). Results: We enrolled 35 evaluable patients. The study was positive. The median PFS was 7.9 (90% CI 6.2-11.8) months (vs. 6 months in historical control, p=0.018). The median overall survival was 16.5 (90% CI 9.8-17.5) months. Sixty-seven percent of patients experienced grade 3 or higher treatment-related adverse events. The most common toxicities were hematological (neutropenia) and gastrointestinal (diarrhea, nausea, and vomiting). Conclusions: Irinotecan, TAS-102 and bevacizumab is an active 2nd line therapy for patients with metastatic colorectal adenocarcinoma. Neutropenia is common and can affect dose density/intensity mandating use of G-CSF. A randomized study versus standard of care therapy is warranted.

REVEAL Study of NKTR-262 in Combination With NKTR-214 and Nivolumab in Patients With Locally Advanced / Metastatic Solid Tumor Malignancies

Project description:Patients received intratumoral (IT) injections of NKTR-262 in 3-week cycles for up to 3 cycles; bempegaldesleukin with or without nivolumab was administered every 3 weeks (q3w), and treatment continued until unacceptable toxicity, death, or disease progression per RECIST 1.1. Based on Phase 1 results of the study, the decision was made not to start the Phase 2 part of the study and the study was terminated.
