Priothera closes €30 million Series A financing to develop highly promising therapies for acute myeloid leukemia (AML)

DUBLIN, Oct. 12, 2020 /PRNewswire/ -- Priothera Limited, a clinical stage company developing orally applied sphingosine 1 phosphate (S1P) receptor modulators for haematological malignancies, today announced that it has successfully closed a Series A financing round of €30 million 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.

Priothera 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 extensively 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.

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.

Florent Gros, Co-Founder and CEO of Priothera, commented, "We are delighted to welcome this terrific syndicate of investors, who share our passion, commitment, and vision for advancing Priothera's potentially best-in-class new therapy, mocravimod, in patients with acute myeloid leukemia and other hematologic malignancies. Allogenic stem cell transplant is the only potentially curative approach for AML patients, but has unacceptably high mortality with current treatments. We are excited about mocravimod which has a unique mechanism of action and clinical proof of concept demonstrating its ability to improve survival outcomes for this devastating disease."

Dr. Dhaval Patel, Co-Founder and Board Director of Priothera, who previously led Research Europe and the Autoimmunity, Transplantation and Inflammation Disease Area at Novartis, known for its success in developing other S1P receptor modulators, stated, "Mocravimod is an outstanding, well-characterized and well-behaved S1P receptor modulator that is well-suited for clinical development and commercial manufacturing. Based on the clinical results to date, mocravimod has the potential to be a best-in-class therapy to decrease the morbidity and mortality associated with HSCT for AML. I have high hopes that Priothera can make an impactful difference for these patients."

Commenting on the launch of the company, Dr. Manus Rogan, Chairman of Priothera added, "The Priothera team has identified and validated a novel commercial opportunity for an S1P receptor modulator allowing the company to complete this significant Series A funding round. With their extensive expertise and capabilities I am confident that Florent and the team are uniquely placed to successfully generate further clinical data to highlight the significant potential of mocravimod."

Priothera

Priothera is leading the way in 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.

Headquartered in Dublin, Ireland, Priothera was founded in 2020 by Drs. Florent Gros and Dhaval Patel. Joining the founding team are the experienced industry executive, Dr. Christoph Bucher, Dr Simone Seiter, and Brice Suire.

Founding investors are Fountain Healthcare Partners (Dublin, Ireland), funds managed by Tekla Capital Management, LLC (Boston, Massachusetts), HealthCap (Stockholm, Sweden) and EarlyBird Venture Capital (Berlin, Germany).
