Priothera – Clinical Mocravimod Data in Hematological Malignancies Patients Undergoing Allogeneic Hematopoietic Stem Cell Transplant (aHSCT) Presented at the 2022 European Hematology Association (EHA) Congress

Phase 1b/2a data shows that mocravimod is safe and well tolerated

Dublin, Ireland – 13th June 2022 – Priothera, a late-clinical stage biotechnology company pioneering the development of its S1P receptor modulator compound, mocravimod, presented first clinical data on mocravimod (also known as KRP203) in hematological malignancies patients undergoing allogeneic hematopoietic stem cell transplant (HSCT) at the European Hematology Association (EHA) 2022 Congress, which was held in Vienna, Austria, June 9-12th, 2022.

The oral presentation, which took place on 12th June, was entitled A two-part, single- and two-arm randomized, open-label study to evaluate the safety, tolerability and pharmacokinetics of KRP203 in subjects with hematological malignancies undergoing allogeneic hematopoietic stem cell transplantation. The study showed that in the Phase 1b/2a study mocravimod was safe and well tolerated with promising overall survival.

Key take aways from the data presentation were:

  • The study provided first ever human data of a S1P receptor modulator administered to patients undergoing allogeneic HSCT
  • S1PR modulator class effects, such as bradycardia, were of no clinical concern
  • Promising overall survival (OS) data
  • Limited number of relapses, acute and chronic graft-versus-host disease (GVHD)
  • Data supportive for conducting the planned MO-TRANS pivotal study to investigate efficacy (Relapse-free survival and OS) and GVHD in AML patients undergoing allogeneic HSCT

Priothera is initiating the pivotal MO-TRANS global Phase 2b/3 study in Europe, US and Japan, to assess the efficacy and safety of mocravimod as an adjunctive and maintenance therapy in adult AML patients undergoing allogeneic HSCT. The 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, said: “We are delighted to have been given the opportunity to present the full first human clinical data on mocravimod at the European Hematology Association Congress this year. Based on these results mocravimod has the potential to be a first-in-class therapy in maintaining graft-versus-leukemia responses while preventing graft-versus-host disease. This novel approach would provide a tremendous benefit to AML patients undergoing an allogeneic hematopoietic stem cell transplant. We are excited about mocravimod which leverages a well-described mode of action in a hematology/oncology setting and has been successfully used in autoimmune indications. Pre-clinical and clinical proof of concept studies have herewith demonstrated mocravimod’s ability to improve survival outcomes for this devastating disease. We look forward to advancing the global pivotal Phase 2/3 trial which is due to start in the second half of 2022.”

About Mocravimod

Mocravimod (also known as KRP203) is a synthetic, sphingosine 1-phosphate receptor (S1PR) modulator. This novel investigational drug has been assessed in Phase 1 and Phase 2 trials for safety and tolerability, as well as for efficacy in several autoimmune indications. Promising data from a Phase 1b/2a clinical study in patients with hematological malignancies led Priothera to further develop mocravimod for the treatment of blood cancers and the improvement of CART cell therapy.

Mocravimod will be investigated as an adjunctive and maintenance treatment in a Phase 2b/3 study as a potential treatment for patients with Acute Myeloid Leukemia (AML) receiving allogeneic hematopoietic stem cell transplantation (HSCT). Allogeneic HSCT is the only potentially curative approach for AML patients, but current treatments have unacceptably high mortality and morbidity rates.

Priothera leverages S1PR modulator’s unique mode of action to maintain anti-leukemia activity – graft-versus leukemia (GVL) while reducing tissue damage resulting from graft-versus-host disease (GVHD), a consequence of allogeneic HSCT. This novel treatment approach – mocravimod being the only S1PR modulator treating blood cancers – tackles a high unmet medical need and intends to add quality life to patients.

 

About Priothera

Priothera is leading the way in developing orally applied sphingosine-1-phosphate (S1P) receptor modulators for the treatment of hematological malignancies and for the improvement of CART cell therapies. S1P receptor modulators are known to largely reduce egress of T cells from lymphatic tissues. Not being an immunosuppressant, mocravimod maintains the graft-versus-leukemia (GVL) benefits in patients receiving HSCT while inhibiting graft-versus-host-disease (GVHD).

Priothera was founded in 2020 by an experienced team of drug development experts and is headquartered in Dublin, Ireland, and with a subsidiary in Saint-Louis, France. The Company is backed by international founding investors Fountain Healthcare Partners (Dublin, Ireland), funds managed by Tekla Capital Management, LLC (Boston, Massachusetts), HealthCap (Stockholm, Sweden) and EarlyBird Venture Capital (Berlin, Germany).

Background

The success of allogeneic hematopoietic stem cell transplantation (HSCT) is limited by disease relapse. Alloreactive donor T cells have the potential to reject residual malignant cells and are essential to prevent relapse by graft-versus-leukemia (GVL) effect. This GVL response is very powerful, however, the same T cells cause acute graft-versus-host disease (aGVHD). T cell trafficking from lymphoid organs is a major step in the development of aGVHD and is regulated by sphingosine-1-phosphate (S1P) gradients. Pre-clinical data showed that pharmacological modulation of S1P receptor (S1PR) signaling by KRP203 sequesters T cells in lymphoid organs and prevents their egress to aGVHD target sites. In murine models, KRP203 efficiently reduced aGVHD without suppressing T cell function, while GVL was maintained and survival improved. Here, we show data of the first clinical trial investigating S1PR modulation by KRP203 as GVHD prophylaxis while maintaining GVL in patients undergoing HSCT for the tratement of hematological malignancies.

Study design

This multicentric, phase Ib, prospective, open label, two-part study evaluated safety, tolerability and pharmacokinetics of KRP203 in intermediate to high-risk patients undergoing allogeneic HSCT for hematological malignancies. Three treatment arms were investigated: 3 mg KRP203 + cyclosporine A (CsA)/methotrexate (MTX) (CsA3), 1 mg KRP203 + CsA/MTX (CsA1) and 3 mg KRP203 + tacrolimus (Tac)/MTX (Tac3). KRP203 was administered daily from day 1 until day 111 and HSCT was performed on day 11.

Results

Upon KRP203 treatment, absolute lymphocyte counts (ALC) stabilized above 0.2×109/L but were efficiently reduced in all three treatment arms below pre-HSCT level (<0.7×109/L). Tretment effect was resolved when KRP203 was stopped on day 111, which caused an increase in blood ALC to pre-HSCT level. CD4+ and CD8+ T cells, GVL mediators and major players in the pathophysiology of aGVHD, were reduced in peripheral blood in response to KRP203 treatment. Only CD4+ T cells remained below pre-HSCT level (<100 cells/μl).

Overall survival probaility was highest for subjects in the CsA3 arm with the first death reported on day 532. Overall survival at 1 year was 100% in the CsA3 arm, 67% in the CsA1 arm and 36% in the Tac3 arm. The median time to relapse was 749 days. 2/6 subjects in the CsA1 arm, 4/10 subjects in the CsA3 arm and 4/7 subjects in the Tac3 arm reported relapse. The median time to any aGVHD was 55 days and 21.7% of subjects presented with grade III-IV aGVHD. The median time to any chronic GVHD was 174 das and 56.5% of subjects presented with moderate and 8.7% with severe chronic GVHD. 52.2% of subjects did not experience a GRFS event and were alive at 6 months.

Conclusion

KRP203 shows promising early clinical outcome with a limited number of relapses, acute and chronic GVHD. The results of this small study support the further investigations of mocravimod in a homogeneous patient population undergoing allogeneic HSCT to confirm safety and assess clinical efficacy, such as overall survival, relapse-free survival and GVHD-free survival.
