Experimental: NKTR-214 Dose Escalation
This is a first in human, open-label, sequential dose escalation and expansion Phase 1 study of NKTR--214 in adult patients with locally advanced and metastatic solid tumors. The Phase 1 stage of the study is designed as an open-label dose escalation trial of NKTR--214 in participants with locally advanced or metastatic solid tumors. The goal of the dose escalation stage of the study is to find the recommended phase 2 dose, to evaluate the efficacy of NKTR--214 by assessing the objective response rate and to evaluate the safety of NKTR-214. Immunological biomarkers in plasma and tumor samples will also be measured.
|
Drug: NKTR-214
Participants in the dose escalation cohorts will be treated every 21 days (q21d) or every 14 days (q14d) until tumor progression. |
- Safety of NKTR-214 as Evaluated by Incidence of Drug-related Adverse Events (AEs) [ Time Frame: 30 days after last dose, approximately 533 days ]This outcome quantifies the number and types of adverse events associated with NKTR-214.
- Tolerability of NKTR-214 as Evaluated by Incidence of Dose Limiting Toxicities (DLTs) [ Time Frame: 30 days after last dose, up to 533 days ]The data below reflects the incidence of Dose Limiting Toxicity Events observed in this trial.
