About
This study is to assess the safety and tolerability, and to assess the preliminary clinical benefit of NKTR-214 when combined with pembrolizumab (KEYTRUDA®) with or without chemotherapy.
The study is comprised of two groups; dose optimization and dose expansion cohorts.
Dose Optimization included first-line and second-line advanced or metastatic solid tumors including non-small cell lung cancer (NSCLC)
The dose expansion cohort will include first-line NSCLC patients.
Full description
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 evaluated an every three-week dose regimen (q3w) of NKTR-214 in combination with pembrolizumab 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.
Dose Expansion: NKTR-214 in combination with pembrolizumab 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.
