Rilematovir is an investigational small molecule drug developed by Johnson & Johnson. It is in Phase 1 clinical development, and its intended therapeutic indication has not been publicly disclosed. It is not approved for any use and remains an experimental compound being studied in early-stage human research.
Rilematovir is developed by Johnson & Johnson, which trades on the New York Stock Exchange under the ticker JNJ. The company sponsored the Phase 1 clinical study of the compound conducted in Belgium. No partnership or licensing arrangement for Rilematovir has been disclosed.
Rilematovir is in Phase 1 clinical development. One Phase 1 trial has been completed, and no active trials are currently listed. Because it is investigational, Rilematovir is not FDA approved, and no regulatory submission or approval has been announced for the compound.
Rilematovir has been studied in one completed Phase 1 trial, NCT05155007, titled a study in healthy adult participants to assess the effects of ciclosporin administration on Rilematovir. The trial enrolled 18 healthy adult volunteers in Belgium, used a controlled, randomized design, and included participants aged 18 years and older.
NCT05155007 evaluated how ciclosporin administration affects Rilematovir in healthy adult participants. The completed Phase 1 study enrolled 18 volunteers in Belgium, was randomized and controlled, and was not double blinded. It was conducted in healthy volunteers rather than in patients with a specific disease.
