Phase Ib study expected to initiate in H2 2024
Previously reported Phase I results showed MOv18 IgE to be safe and well tolerated, with evidence of anti-tumour activity LONDON, UK I July 08, 2024 I Epsilogen, a global leader in the development of immunoglobulin E (IgE) antibodies to treat cancer, today announces that the Clinical Trial Application for the Phase Ib trial of MOv18 IgE has been approved by the UK Medicines and Healthcare products Regulatory Agency (MHRA). Dr Tim Wilson, Chief Executive Officer of Epsilogen, said: “This CTA is another significant milestone for Epsilogen and the clinical development of MOv18 IgE. We look forward to progressing MOv18 IgE into a Phase Ib efficacy study later this year as we continue to demonstrate the potential of IgE antibodies as a new, differentiated class of cancer treatments.” The Phase Ib study is designed to confirm the safety and tolerability of MOv18 IgE and demonstrate efficacy in PROC. Following the dose escalation, an expansion cohort will be recruited to make a preliminary assessment of the anti-tumour activity of MOv18 IgE at a selected dose. In addition, delay to disease progression will be assessed along with a number of translational elements to generate further understanding of MOv18 IgE in the study population. Epsilogen is a global leader in the development of immunoglobulin E (IgE) antibodies to treat cancer. IgE’s natural function is to provide immunological defence against certain parasites. This functionality makes it an ideal treatment of solid tumours due to its strong potency, enhanced tumour access and long tissue half-life. Epsilogen’s lead product candidate, MOv18 IgE, is the first therapeutic IgE antibody to enter the clinic and encouraging data from a completed Phase I trial demonstrated MOv18 IgE to be safe and well tolerated with early signs of clinical activity. Epsilogen has recently successfully completed large scale GMP manufacture of MOv18 IgE (the first time this has been achieved for an IgE antibody) and will initiate a Phase Ib trial in platinum-resistant ovarian cancer patients later this year. The company is also developing a pipeline of IgE therapies in oncology as well as proprietary platforms including IgE bispecifics and unique IgE/IgG combination antibody molecules (IgEGs) with enhanced functionality.
