A few weeks after receiving regulatory approval from European Medicines Agency (EMA), the European trial of our MPX-RESPONSE project effectively started this summer with the enrolment of its first participant on 15 August. Key points to know.

The European randomised clinical trial in mPOX Infection (EPOXI) is a randomized, controlled, double-blinded trial, designed to capture and investigate sporadic cases of mpox in Europe and to evaluate promising treatment options.

Compliant with the current EU regulatory framework, the study represents one of the first multinational clinical trials in the EU/EEA for an epidemic defined by the World Health Organization as a global public health emergency. Designed to enroll 150 subjects across 8 to 10 European countries, EPOXI will primarily evaluate the efficacy and safety of the antiviral drug tecovirimat. The study is designed to plan a joint analysis with UNITY, the international multi-regional study of MPX-RESPONSE.

How can EPOXI optimize European pandemic preparedness ?

“The EPOXI trial is among the first multinational academic studies set up in the EU that targets a novel epidemic. It has yielded a huge amount of experience and will allow us to respond more quickly to new infectious threats in the future. We realize now that the major hurdles and delays are not scientific or medical, but that they concern financing, regulations and contracts.”

Dr. Miquel Ekkelenkamp,principal investigator of EPOXI, UMC Utrecht, the Netherlands

Why tecovirimat ?

According to the International Pandemic Preparedness Secretariat, Tecovirimat SIGA remains the primary focus of therapeutic research, with several trials exploring its potential in various settings. This antiviral was initially approved for mpox treatment in the EU (EMA) under exceptional circumstances but clinical data are still missing to assess its efficacy and explore its utility across different patient groups.

Focus on the partners for our EPOXI study

EPOXI is one of the 3 clinical trials of the MPX-RESPONSE project. The study is sponsored by University Medical Center Utrecht (UMC) with the management of Ecraid and the pharmacovigilance handled by ANRS MIE. The recruiting sites include Erasmus Medical Centre of Rotterdam (EMC), University of Antwerp (UA), Servicio Madrileno de Salud (SERMAS), Oslo University Hospital (OUH), Assistance Publique des Hôpitaux de Paris (AP-HP).
