Résumé de l'étude

Monkeypox is a disease caused by the monkeypox virus (MPXV), which has been spreading rapidly in Europe since May 2022. There is only one antiviral drug approved in the European Union (EU) for the treatment of monkeypox, and no treatment is yet approved in Switzerland. This drug is tecovirimat (TPOXX®). As this disease is rare, the efficacy and safety of tecovirimat have primarily been evaluated in animals and healthy volunteers. This study aims to gather more information on the efficacy and safety of this drug in patients with monkeypox. To determine if tecovirimat (the experimental product) is effective, we will compare it to a product that does not contain an active compound, meaning some people participating in the study will receive a "placebo". The placebo looks like the experimental product but contains no active substance, only inactive ingredients. Of two people participating in this study, one will receive the experimental product and the other the placebo. The participant and the study staff will not know whether the participant is receiving the experimental product or the placebo. This study will include adults and adolescents (aged 14 years and older).

(BASEC)

Intervention étudiée

The experimental product (tecovirimat) or the placebo will be taken two or three times a day (depending on the participant's weight), every day for 14 consecutive days.

The intake will be oral.

 

In addition to receiving tecovirimat or placebo, all participants will receive routine care ("standard of care").

Maladie en cours d'investigation

Monkeypox (monkeypox - mpox)

(BASEC)

Critères de participation
- Adults and adolescents (aged 14 years and older) with laboratory-confirmed monkeypox (PCR if available) or with a strong suspicion of infection, of any duration - At least one visible active lesion of the skin or mucous membrane - Reachable via smartphone (for video calls) for outpatient participants - Signed informed consent (BASEC)

Critères d'exclusion
- Current or planned use of another experimental drug at any time during participation in the study - Patients who, in the opinion of the investigator, will be at significantly increased risk by participating in the study (e.g.: if the investigator believes that antiviral treatment is not indicated) - Hypersensitivity to tecovirimat (BASEC)
