IgE’s natural function is to provide immunological defense 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 phase I trial demonstrated MOv18 IgE to be safe and well tolerated with early signs of clinical activity also seen. The company is also developing a proprietary IGEGTM antibody platform combining elements from both IgE and IgG antibodies into novel and proprietary antibody molecules with enhanced functionality.
