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 Pharma 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 first-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 and 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."

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.

Bayer receives approval for Vitrakvi™ in Japan

On March 23, 2021 Bayer reported that the Japanese Ministry of Health, Labor and Welfare (MHLW) has granted marketing authorization for larotrectinib, under the brand name Vitrakvi, for the treatment of Neurotrophic Tyrosine Receptor Kinase (NTRK) fusion-positive advanced or recurrent solid tumors (Press release, Bayer, MAR 23, 2021, View Source;ref=irrefndcd#:~:text=Berlin%2C%20March%2023%2C%202021%20%E2%80%93,advanced%20or%20recurrent%20solid%20tumors [SID1234613723]). Vitrakvi is a highly selective TRK inhibitor exclusively designed to treat tumors that have an NTRK gene fusion. Vitrakvi has demonstrated high response rates, durable responses and a favorable safety profile in adults and children with TRK fusion cancer. For those patients with primary central nervous system (CNS) tumors and with CNS metastases, responses and a high disease control rate have been observed. It is already approved in the U.S., countries of the European Union (EU), the UK and other markets around the world.

"There remains a high unmet need for new and innovative cancer treatments in Japan. The approval of Vitrakvi marks an important step towards treating TRK fusion cancer based on the oncogenic driver rather than the site or origin in the body," said Makoto Tahara, MD., Ph.D. Chief, Department of Head and Neck Medical Oncology, National Cancer Center Hospital East. "Clinicians now have the option to replace less tailored treatment approaches with a precision oncology treatment specifically designed to treat patients with TRK fusion cancer."

The marketing authorization of Vitrakvi follows the approval of the expanded use of FoundationOneCDx, a comprehensive genomic profiling (CGP) test, in Japan for use as a companion diagnostic (CDx) to identify patients with TRK fusion cancer who are expected to benefit from treatment with Vitrakvi. The CDx approval is part of the global collaboration between Bayer and Foundation Medicine, Inc. (FMI), for which Chugai is the local development partner of FMI.

"Treatments that directly address the genomic abnormality driving tumor growth, such as Vitrakvi, can provide value to patients and physicians in Japan with the potential to significantly improve treatment outcomes regardless of tumor type or patient age," said Scott Z. Fields, M.D., Senior Vice President and Head of Oncology Development at Bayer’s Pharmaceutical Division. "This approval further underscores the importance of high quality and accessible genomic testing to allow more precise identification of patients who are most likely to benefit from a treatment specifically designed to treat tumors with an NTRK gene fusion. It supports clinicians to get the right treatment, that is efficacious and has a favorable safety profile, to the right patient at the right time."

The approval of Vitrakvi in Japan is based on data from 125 patients from the Phase II NAVIGATE trial in adult and adolescent patients and the Phase I/II pediatric SCOUT trial. Results analyzed from the NAVIGATE trial population showed an overall response rate (ORR) of 65.2% with a complete response (CR) rate of 16.9% and in SCOUT an ORR of 88.9% with a CR rate of 22.2%. Larotrectinib showed a favorable safety profile based on the safety data from 116 patients in the NAVIGATE trial and 73 patients in the SCOUT trial.

TRK fusion cancer is rare overall, affecting both children and adults and occurs in varying frequencies across various tumor types. TRK fusion cancer occurs when an NTRK gene fuses with another unrelated gene, producing an altered TRK protein. The altered protein, or TRK fusion protein, becomes constitutively active or overexpressed, triggering a signaling cascade. These TRK fusion proteins act as oncogenic drivers that fuel the spread and growth of the patients’ cancer, regardless of where it originates in the body. Vitrakvi, an oral, highly selective TRK inhibitor, was investigated in clinical trials across multiple different histologies of solid tumors including lung and thyroid cancer, melanoma, gastrointestinal stromal tumors, colon and breast cancer, soft tissue sarcomas, salivary gland cancer and infantile fibrosarcoma. It has shown remarkable efficacy and tolerability across tumor types regardless of patient age in clinical trials with a follow-up time of more than three years in adults and children with TRK fusion cancer, including central nervous system (CNS) tumors.

About Vitrakvi (Larotrectinib)
Vitrakvi (larotrectinib), a highly selective TRK inhibitor, was exclusively designed to treat tumors that have a NTRK gene fusion. The compound has demonstrated high response rates and durable responses over three years in adults and children with TRK fusion cancer, including responses and a high disease control rate in central nervous system (CNS) tumors. It has the largest dataset and longest follow-up data of any TRK inhibitor. The dataset of 159 patients was published in The Lancet Oncology and additional updates were presented at the ESMO (Free ESMO Whitepaper) Virtual Congress 2020.

Vitrakvi is approved in more than 40 countries, including the U.S., countries of the European Union (EU), the UK and other markets around the world. Additional filings in other regions are underway or planned.

Following the acquisition of Loxo Oncology by Eli Lilly and Company in February 2019, Bayer now possesses the exclusive rights to develop and commercialize larotrectinib worldwide, and also has exclusive rights to the investigational TRK inhibitor selitrectinib (BAY 2731954) which is currently in clinical development.
