Summary

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.

Description

NKTR-255 is a cytokine that is designed to regulate T and natural killer cell activation, proliferation and promote their anti-tumor effects.

In the dose escalation (Phase 1/b) phase patients with HNSCC or CRC will be treated with ascending doses of NKTR-255 in combination with cetuximab, until the maximum tolerated dose (MTD) and/or the recommended Phase 2 dose (RP2D) is reached. The recommended phase 2 dose of NKTR-255 will be used to treat patients in Phase 2 of this study.

In the dose expansion phase (Phase 2), patients will be treated with NKTR-255 alone and together with cetuximab as follows: Cohort A - HNSCC; Cohort B - CRC; Cohort C - cSCC; Cohort D - ASCC; Cohort E - Cervical Cancer.

Patients who achieve optimal response will be given the option to continue treatment with NKTR-255 as single agent for maintenance.
