Step Pharma publishes data identifying the key role of CTP Synthase 1 in haematological malignancies

Press Release

St. Genis-Pouilly, France, 04 April 2023

  • Preclinical data published in HemaSphere demonstrate potential of inhibiting CTPS1 as a novel treatment approach for cancer
  • Data further support rationale for developing STP938, currently in clinical trials for the treatment of T cell and B cell lymphoma

Step Pharma, the world leader in CTPS1 inhibition for the targeted treatment of cancer, today announces the publication of compelling preclinical data detailing the therapeutic potential of inhibiting CTPS1 in haematological malignancies.

The data, published in HemaSphere (the official journal of the European Hematology Association), describe the identification and characterisation of CTP synthase 1 (CTPS1), an enzyme that catalyses a rate-limiting step in pyrimidine synthesis, as a novel therapeutic target in T cell and B cell malignancies.

Step Pharma’s selective CTPS1 inhibitors induced cell death of neoplastic lymphoid cells in vitro and demonstrated anti-tumour activity in vivo in models of both T cell and B cell malignancies.

STP938, a first-in-class, highly selective, orally bioavailable inhibitor of CTPS1 recently entered a Phase 1/2 trial for T cell and B cell lymphomas (NCT05463263) and study sites are open in the UK and the USA.

Lymphoma is the most common haematological malignancy. Despite improvements in patient survival with modern immunochemotherapy treatments, there remains a significant need for novel targeted agents to treat both T cell and B cell malignancies.

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

“Our deep understanding of the pyrimidine synthesis pathway and CTPS1 biology has yielded a new targeted approach to treating blood and solid tumours. This publication summarises the important work undertaken by Step Pharma, providing compelling evidence for CTPS1 being a key therapeutic target in T and B cell malignancies. We are pleased to have developed a host of CTPS1 small molecule modulators and to be conducting Phase 1/2 clinical trials with the most advanced CTPS1 inhibitor in the world, STP938. Our ultimate goal is to drive a step change in the way we treat cancer and make a real difference in patients’ lives.”

Step Pharma Announces First Patient Dosed with STP938, the World’s Most Advanced CTPS1 Inhibitor, in a Phase 1/2 Trial for T cell and B cell lymphomas

Press Release

St. Genis-Pouilly, France, 24 October 2022

Potential first-in-class targeted treatment for relapsed/refractory T cell and B cell lymphomas

Step Pharma, the world leader in CTPS1 inhibition for the targeted treatment of cancer, announces today that the first patient has been successfully dosed with STP938, in a Phase 1/2 trial in adult subjects with relapsed/refractory B cell and T cell lymphomas.

The dose-escalation part of the open label, non-randomised Phase 1/2 trial comprises multiple cohorts dosed with STP938, administered as an oral monotherapy, ascending in a stepwise manner. The primary objective in Phase I is to assess the safety and tolerability of STP938.

Brian Schwartz, Chief Medical Officer of Step Pharma, commented:

“We are developing STP938, a highly selective, first-in-class treatment based on ground-breaking genetics. The dosing of the first patient into our Phase 1/2 trial is an important step to identify an optimal dose to take forward into further clinical development for relapsed/ refractory T cell and B cell lymphomas.”

STP938 is a first-in-class oral cancer therapeutic 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.

Further details of the study can be found on clinicaltrials.gov under the identifier NCT05463263.

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.
