• Target enrollment: 0
• Participant gender: All

Summary

The main purpose of this phase-1b, multicenter, randomized double-blind, placebo-controlled, trial is to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of bempegaldesleukin (BEMPEG; NKTR-214) in combination with standard of care (SOC) in adult patients with mild COVID-19 (coronavirus disease 2019).
