Phase III, randomized, placebo-controlled, double-blind trial to evaluate the safety and efficacy of antiviral treatment with tecovirimat in patients with monkeypox (UNITY study)
Zusammenfassung der Studie
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)
Untersuchte Intervention
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").

Ein-/Ausschlusskriterien
Inclusion Criteria:
- Adults and adolescents (14 years old and older) with laboratory-confirmed (PCR if
available) or highly suspected monkeypox virus infection of any duration
- At least one visible active skin or mucosal lesion
- Reachable via smartphone (for video calls) for outpatient participants
- Signed informed consent
Exclusion Criteria:
- Current or planned use of another investigational drug at any point during study
participation.
- Ongoing treatment which cannot be interrupted and for which a major interaction has
been described with tecovirimat
- Patients who, in the judgement of the investigator, will be at significantly
increased risk as a result of participation in the study (for example: if the
investigator judges that an antiviral treatment is indicated in the framework of
compassionate therapeutic access in Switzerland).
