RSM01, a novel respiratory syncytial virus monoclonal antibody: preclinical characterization and results of a first-in-human, randomised clinical trial.

ABSTRACT:

Background

Respiratory syncytial virus (RSV) is a leading cause of lower respiratory tract disease among infants and young children worldwide, especially in low- and middle-income countries (LMICs). RSM01 is a novel, highly potent, half-life-extended anti-RSV monoclonal antibody (mAb) candidate primarily being developed for LMICs. Here we present the preclinical characterisation and results of a phase 1 trial of RSM01.

Methods

Preclinical characterisation of RSM01 was conducted using in-vitro neutralization assays and cotton rat models. In the first-in-human, double-blind, phase 1 trial, 56 healthy adults were randomised 6:1 within dose cohorts to receive a single dose of RSM01 (n = 48) or placebo (n = 8): 300 mg intravenously (IV), 300 mg intramuscularly (IM) or 1000 mg IV
