Clinical Trial Summary

The purpose of this study is to evaluate the efficacy, safety, pharmacokinetics (PK), neutralizing antibody and antidrug antibody (ADA) response for TNM001 in infants entering their first RSV season.

Description:

This study adopts an adaptive seamless dose selection design and consists of two parts: Part 1 is a phase 2b dose ranging trial which will support to determine the dose for Part 2, the phase 3 trial. The study population includes early and mid-term preterm infants [gestational age (GA)﹤35 weeks 0 day] and late preterm infants or full-term infants (≥35 weeks 0 day GA), with or without Congenital Heart Disease (CHD) or premature infants Chronic Lung Disease (CLD). A total of approximately 2250 infants will be randomized 2:1 to receive either TNM001 or placebo. All subjects will be followed for 240 days after dosing. This study will be conducted in appropriately 50 sites in China.
