NKTR-214 is a cytokine (investigational agent) that is designed to target CD122, a protein which is found on certain immune cells (known as CD8+ T Cells and Natural Killer Cells) to expand these cells to promote their anti-tumor effects. Pembrolizumab is a programmed death receptor -1 (PD-1) blocking, fully humanized, engineered monoclonal antibody of IgG1 isotype that promotes anti-tumor effects. The study will evaluate the clinical benefit, safety and tolerability of combining NKTR-214 with pembrolizumab with or without chemotherapy. Each dose expansion cohort will enroll approximately 100 new patients. Dose Optimization: will evaluate an every three-week dose regimen (q3w) of NKTR-214 in combination with pembrolizumab in approximately 40 patients given that the optimal dose and dosing schedule of NKTR-214 in combination with pembrolizumab remains unknown. The previously established recommended Phase 2 dose (0.006 mg/kg) of NKTR-214 was studied in combination with nivolumab. Tumors to be studied include first-line and second-line melanoma, non-small cell lung cancer (NSCLC), urothelial carcinoma, head and neck squamous cell carcinoma (HNSCC), and hepatocellular carcinoma (HCC). NKTR-214 will be administered at a starting dose of 0.008 mg/kg q3w. Pembrolizumab will be administered at a dose of 200 mg q3w. Patients will undergo a fixed 3+3 dose escalation followed by intra-patient step-up dose escalation at a dose determined by the safety review committee after reviewing the data in the fixed 3+3 dose escalation. Dose Expansion: NKTR-214 in combination with pembrolizumab in approximately 58 patients will be evaluated in first-line non-small cell lung cancer (NSCLC). The NKTR-214 dose to be studied is 0.006 mg/kg q3w. This dose is based on the recommended phase 2 dose noted in the monotherapy trial with NKTR-214 (Study 15-214-01, NCT02869295) and an ongoing combination trial (16-214-02, NCT02983045). Pembrolizumab will be administered at a dose of 200mg q3w. Following data review for safety and efficacy, additional patients may be dosed using the findings from the dose optimization cohorts.
