The Phase Ib study is expected to initiate later in 2024 and will evaluate the efficacy of MOv18 IgE in patients with platinum-resistant ovarian cancer (PROC).

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."

About MOv18 IgE

MOv18 IgE is an immunoglobulin E (IgE) antibody targeting the folate receptor alpha (FR alpha) antigen. FR alpha is present on a variety of cancers including ovarian, endometrial, lung and triple negative breast cancer. Epsilogen has successfully completed a Phase I safety study of MOv18 IgE in PROC patients. The results of the study, published in Nature Communications, found MOv18 IgE to be safe and well tolerated, with evidence of anti-tumour activity observed. Epsilogen, alongside its partner Lonza, also announced the successful completion of large-scale Good Manufacturing Practice (GMP) manufacturing of MOv18 IgE earlier this year.

About the Phase Ib study

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.
