Pharmacokinetic analysis will include listings and summaries of midazolam concentration by time point and analysis of relationship with dose and body weight

Assess terminal half life of (t1/2) of midazolam (as index substrate) before and after dosing with RV299.
Part B Cohort 3 only: pre-dose, 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 9, 12, 13, 16, and 24 hours following administration of midazolam on Day 1 and Day 7.

Pharmacokinetic analysis will include listings and summaries of midazolam concentration by time point and analysis of relationship with dose and body weight

Assess maximum plasma concentration (Cmax) of midazolam (as index substrate) before and after dosing with RV299.
Part B Cohort 3 only: pre-dose, 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 9, 12, 13, 16, and 24 hours following administration of midazolam on Day 1 and Day 7.

Pharmacokinetic analysis will include listings and summaries of midazolam concentration by time point and analysis of relationship with dose and body weight

Frequently asked questions about RV299

What is RV299 used for?

RV299 is an investigational small molecule being developed by Pfizer for the treatment and prevention of Respiratory Syncytial Virus (RSV) infections. It is currently in Phase 1 clinical development and has not been approved by regulatory authorities.

Who is developing RV299?

RV299 is being developed by Pfizer, Inc., a biopharmaceutical company listed on the New York Stock Exchange under the ticker symbol PFE. The drug is currently in Phase 1 clinical trials for Respiratory Syncytial Virus (RSV) infections.
