Background: A single-dose investigational respiratory syncytial virus (RSV) vaccine, RSV prefusion protein F3 (RSVPreF3), was co-administered with a single-dose quadrivalent influenza vaccine (FLU-D-QIV) in a phase 3, randomized, controlled, multicenter study in healthy, non-pregnant women aged 18-49 years.
Methods: The study was observer-blind to evaluate the lot-to-lot consistency of RSVPreF3, and single-blind to evaluate the immune response, safety, and reactogenicity of RSVPreF3 co-administered with FLU-D-QIV.
Results: A total of 1415 participants were included in the per-protocol set.
Background: Respiratory syncytial virus (RSV) fusion protein stabilized in the prefusion conformation (RSVPreF3) was under investigation as a maternal vaccine.
Methods: This phase 2, randomized, placebo-controlled, single-dose, multicenter study enrolled healthy, nonpregnant women, randomized 1:1:1:1:1 to 5 parallel groups studying RSVPreF3 (60 or 120 µg) coadministered with diphtheria, tetanus, and acellular pertussis vaccine (dTpa) or placebo, and dTpa coadministered with placebo. Safety and humoral immune responses were assessed.
Objective: This study evaluated the utilisation of human pharmacology studies with biomarkers for either efficacy or safety estimation conducted for new drug applications (NDAs) submitted to the Japanese regulatory authority, the Ministry of Health, Labour and Welfare (MHLW).
Methods: A total of 50 new chemical entities (NCEs) posted on the Websites, which were approved from June 2000 to November 2001, were evaluated by investigating their approval information. The utilisation of human pharmacology studies with biomarkers was evaluated by focusing on the classification referred to biomarkers for either efficacy or safety estimation and timing of studies.
