Priothera Raises €30M in Series A Financing


Priothera, a Dublin, Ireland-based clinical stage company developing orally applied sphingosine 1 phosphate (S1P) receptor modulators for haematological malignancies, closed a €30m Series A financing round.

The round was led by Fountain Healthcare Partners with participation from co-lead investor HealthCap and funds managed by Tekla Capital Management, LLC as well as EarlyBird Venture Capital.

The company will use the funds to progress the clinical development of mocravimod, a modulator of sphingosine 1 phosphate (S1P) receptors, to enhance the curative potential of allogenic hematopoietic stem cell transplantation (HSCT) for treating AML. Priothera expects to generate further randomized clinical data in high risk AML patients with this Series A funding round. Mocravimod has already been tested in multiple immunologic indications and has shown survival benefit in an early clinical study evaluating acute myeloid leukemia (AML) and acute lymphocytic leukemia (ALL) patients undergoing hematopoietic stem cell transplantation (HSCT). Priothera acquired mocravimod from KYORIN Pharmaceutical Co., Ltd.

Founded in 2020 by Drs. Florent Gros and Dhaval Patel, Priothera is developing orally applied sphingosine 1 phosphate (S1P) receptor modulators for haematological malignancies. S1P receptor modulators have been suggested to largely reduce egress of T cell subsets from lymphatic tissues allowing for dual inhibition of graft-versus-host-disease (GvHD) and enhancing graft-versus-leukemia benefits in patients receiving allogenic stem cell transplant.

Joining the founding team are the experienced industry executive, Dr. Christoph Bucher, Dr Simone Seiter, and Brice Suire.

Following the closing of the financing, Florent Gros (Priothera’s Co-Founder and CEO), Dr. Dhaval Patel (Priothera’s Co-Founder and CSO at UCB), Dr. Manus Rogan (Fountain Healthcare Partners Co-Founder and Managing Director), Dr. Mårten Steen (Partner at HealthCap), Dr. Henry Skinner (Senior Vice President at Tekla Capital Management, LLC) and Lionel Carnot (Partner at EarlyBird Venture Capital), have joined the Board of Directors.
