Priothera Receives First Regulatory Approvals to Start a Global Pivotal Study with Mocravimod in Acute Myeloid Leukemia Patients Undergoing Allogeneic Hematopoietic Stem Cell Transplant

- Global Phase 2b/3 trial assessing the efficacy and safety of mocravimod as an adjunctive and maintenance therapy in AML patients undergoing allogeneic HSCT planned to start in H2 2022

Dublin, Ireland - 11th April 2022 – Priothera Ltd, a late-clinical stage biotechnology company pioneering the development of its S1P receptor modulator mocravimod, today announces it has received the two first European country approvals from the Swiss and French national health authorities (Swissmedic and ANSM) to begin its planned pivotal study of mocravimod. The company has also received encouraging feedback from the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) on the clinical study design that is closely aligned with earlier feedback from the US Food and Drug Administration (FDA).

Priothera will initiate a global Phase 2b/3 study (MO-TRANS study) in Europe, US and Japan, assessing the efficacy and safety of mocravimod as an adjunctive and maintenance therapy in adult Acute Myeloid Leukemia (AML) patients undergoing allogenic hematopoietic stem cell transplant (HSCT). The MO-TRANS study is expected to start in the second half of 2022 and preliminary data from this study are expected by the end of 2024.

Florent Gros, Co-Founder and CEO of Priothera, commented “Following on from our recent receipt of orphan drug designations for mocravimod in the US and Europe, we are pleased to have received our first approvals to initiate this key global Phase 2b/3 trial with this highly promising compound. Moreover, the CHMP feedback is encouraging, and is also closely aligned with the feedback we received from the FDA. These first approvals are important regulatory and clinical milestones for Priothera and move us a step closer to bringing mocravimod, an adjunctive and maintenance treatment, to patients with AML and other hematologic malignancies, for whom there remains a significant unmet medical need.”
