Step Pharma Progresses into Oncology Clinical Trials with STP938, the World’s Most Advanced CTPS1 Inhibitor

Press Release

St. Genis-Pouilly, France, 28 July 2022

  • Clearance of IND and CTA applications in the US and UK for STP938 for the treatment of T cell and B cell lymphomas

  • First-in-class targeted therapy with potential applications in multiple cancer indications

  • Novel mechanism of action with high selectivity has the potential to yield an oral treatment with minimal side effects

Step Pharma, a world leader in CTPS1 inhibition for the targeted treatment of cancer, announces today that its lead asset STP938 has cleared both an Investigational New Drug (IND) application by the Food and Drug Administration (FDA), and a clinical trial application (CTA) by the UK’s Medicines and Healthcare products Regulatory Agency (MHRA), enabling Step Pharma to progress STP938, its first-in-class, selective CTPS1 inhibitor into the clinic in the US and UK.

STP938 has now entered an open label, first-in-human, Phase 1/2 study to evaluate the safety, tolerability, pharmacokinetics, and preliminary efficacy of STP938 in adult subjects with relapsed/refractory B cell and T cell lymphomas. Further details of the study can be found on clinicaltrials.gov under the identifier NCT05463263. Patients with such cancers currently face high relapse rates from existing treatments.

Step Pharma is pioneering a novel class of oral drugs that specifically inhibits nucleotide synthesis and the enzyme cytidine triphosphate synthase 1 (CTPS1) in particular, originally identified as an essential gene for lymphocyte proliferation. By targeting CTPS1, Step Pharma has unlocked the ability to selectively target the de novo pyrimidine synthesis pathway in cancer cells. This ground-breaking approach should enable the highly selective treatment of both blood cancers and solid tumours.

Andrew Parker, Chief Executive Officer of Step Pharma, said:

“Our unique approach to cancer treatment has the potential to yield a novel targeted cancer therapy that can form the backbone of both blood and solid tumour cancer treatment regimens. We are delighted to have moved STP938 into the clinic for hard-to-treat lymphomas with the ultimate goal of improving the lives of millions of cancer patients.”

Dr. Brian Schwartz, Chief Medical Officer, commented:

“The clinical trial approvals by both the US FDA and UK MHRA are a significant milestone for Step Pharma and our highly differentiated lead candidate STP938, as we become a clinical-stage company and move at speed to bring this first-in-class treatment to cancer patients with high unmet medical needs.”

Step Pharma will initially investigate STP938 in blood cancers, with a focus on T cell lymphomas, where there has been no improvement in five-year survival rates for over 20 years. However, as studies have shown that all cancer cells require CTPS1 for DNA synthesis, STP938 could be a key component of a multitude of cancer treatment regimens.

Step Pharma Presents Encouraging Data on its First-in-Class CTPS1 Inhibitor STP938 at the European Hematology Association Congress

Press Release

St. Genis-Pouilly, France, 10 June 2022

Step Pharma, a world leader in CTPS1 inhibition for the targeted treatment of cancer, announces today that it is presenting encouraging data in three posters for its first-in-class, highly selective, orally bioavailable CTPS1 inhibitor STP938 at the European Hematology Association Congress being held June 9-17, 2022 in Vienna, Austria.

The data presented demonstrate the high specificity of CTPS1 inhibition achieved with STP938, with inhibition of human neoplastic T cell growth shown both in vivo and in vitro. Moreover, inhibition of CTPS1 by STP938 shows anti-proliferative activity in multiple myeloma through the induction of replication stress and demonstrates synergistic activity when combined with ATR inhibition.

These data support Step Pharma’s belief in STP938’s targeted cytotoxic potential in haematological cancers. STP938 displays favourable preclinical safety and pharmacological properties and is due to progress into first in human clinical studies in the second half of 2022.

Philip Beer, Head of Research and Translational Medicine at Step Pharma, commented:

“Our promising findings demonstrate the importance of CTPS1 for cancer cell proliferation and the potential of STP938 as a targeted therapy for the treatment of cancers with high unmet clinical need. CTPS1 plays a crucial role in neoplastic cells, where inhibiting its activity could have a significant impact in a number of different cancers, either as monotherapy or in combination with existing or novel cancer drugs. We look forward to progressing this exciting new therapy into the clinic.”

Andrew Parker, Chief Executive Officer of Step Pharma, said:

“Our deep understanding of the pathways and CTPS1 biology has led to the development of STP938, a targeted therapy with predicted superior safety and efficacy profiles compared to existing treatments. We believe that this highly selective treatment has the potential to kill cancer cells without affecting immune cell differentiation and therefore could represent a significant step change in the way we treat cancer.”

Step Pharma Presents Encouraging Data on its First-in-Class CTPS1 Inhibitor STP938 at the European Hematology Association Congress

Press Release

Archamps, France, October 6, 2021

Step Pharma, a biotech company developing novel drugs for oncology and autoimmune diseases, announced today the appointment of Dr. Adrian Senderowicz to its Board of Directors. Dr. Senderowicz is a board-certified medical oncologist with 30 years of experience in drug development and commercialization.

“Adrian has phenomenal expertise in cancer drug development having led numerous oncology clinical trials and also brings regulatory agency experience,” said Andrew Parker, CEO of Step Pharma. “We’d like to welcome him to the Board and look forward to working closely with him as we move forward into clinical studies. Our lead program, STP938, will enter clinical studies for the treatment of heamatological malignancies in 2022.”

 

Dr. Senderowicz was previously Senior Vice President and Chief Medical Officer at Constellation Pharmaceuticals, where he was responsible for the development of a portfolio of compounds leveraging epigenetics. Before Constellation, Dr. Senderowicz was chief medical officer at Cerulean Pharma, where he helped secure fast-track designation for the company’s lead clinical program in two indications. Previously, Dr. Senderowicz held roles of increasing responsibility at Ignyta, Inc, Sanofi Oncology, Tokai Pharmaceuticals and AstraZeneca plc. He began his career as an investigator at the National Cancer Institute before joining the FDA’s CDER. Adrian conducted his Internal Medicine residency training at the Icahn School of Medicine at Mount Sinai and a Clinical Oncology Fellowship at the NCI. He holds an MD from the School of Medicine at the Universidad de Buenos Aires (Argentina). Dr. Senderowicz also sits on the board of Puma Biotechnology.

“Step Pharma’s CTPS1 (cytidine triphosphate synthase 1) platform is extremely promising for cancer indications. I’m looking forward to help guide the company as it moves its first program, STP938, into clinical development for the treatment of haematological malignancies,”

Dr. Senderowicz said.

 

Targeting CTPS1

Cytidine nucleotide triphosphate (CTP) is a precursor required for DNA synthesis and cell division. Patients deficient in the enzyme CTPS1 have an altered immune cell proliferation response to immune challenge but no other deleterious effects. This same pathway supports the uncontrolled growth of cancerous T and B cells, thus inhibiting CTPS1 represents a novel precision oncology approach to specifically block proliferation and induce killing of cancerous cells in lymphoma and leukaemia.

Step Pharma Raises EUR35 Million in Series B Financing to Advance First in Class CTPS1 inhibitor into the Clinic in T Cell Malignancies

Press Release

Archamps, France, 24 March 2021

Step Pharma, a biotech company developing novel drugs for oncology and autoimmune diseases, today announced the successful closing of a EUR35 million Series B financing. New investors Hadean Ventures and Sunstone Life Science Ventures co-led the round, joining existing investors Kurma Partners, Pontifax and Bpifrance, who reinvested through its Innovative Biotherapies and Rare Diseases fund and InnoBio 2 fund. As part of the financing, Jacob L Moresco from Sunstone Life Science Ventures and Walter Stockinger from Hadean Ventures will join the Step Pharma Board of Directors.

The proceeds will be used to advance Step Pharma’s lead proprietary CTPS1 inhibitor, STP938, into clinical development for the treatment of T-cell malignancies. In addition, Step Pharma will use the funding to advance development of CTPS1 inhibitors in other haematological malignancies and solid tumours. CTPS1 (cytidine triphosphate synthase 1) is an enzyme that plays a critical role in DNA synthesis, cell division and proliferation but whose function is highly selective to certain cell types, in particular proliferating T cells, making it an ideal target for drug development.

Roger Franklin, Partner at Hadean Ventures said:

“CTPS1 is an elegant target for the development of drugs in the T-cell malignancy space in which there is significant unmet need. The strength of the underlying science, its support from human genetic work as well as the clear commercial opportunity were key factors in our decision to back Step and co-lead this significant financing. We very much look forward to working with the great team at Step as this exciting programme moves into the clinic.”

 

“Step Pharma is a clear leader in CTPS1 research. They have made significant progress in advancing their 1st in class selective CTPS1 inhibitors toward clinical development and expanding the potential therapeutic applications,”

added Jacob L Moresco from Sunstone Life Science Ventures

“The closing of this Series B will enable Step Pharma to transform into a clinical-stage company, enabling us to advance our lead compound into the clinic in Q1 2022,”

said Andrew Parker, CEO of Step Pharma.

“We’d like to welcome our new investors and thank existing investors for their continued support of the company.”
