A Placebo Controlled Trial of Bempegaldesleukin (BEMPEG; NKTR-214) With Standard of Care in Patients With Mild COVID-19

Purpose

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). The trial will also define the recommended phase 2 dose (RP2D) of bempegaldesleukin in patients with mild COVID-19.
