The Company's development pipeline is based on two novel proprietary platforms:
The first platform, ONCOS, uses oncolytic viruses, an emerging class of biological therapy. ONCOS exclusively uses an adenovirus that has been engineered to be a tumor-targeted immune activator. The platform has the potential to generate therapies with superior efficacy and safety compared to the first approved oncolytic virus therapy, Imlygic®, launched by Amgen. We continue to expect key proof of concept data for this platform in 2017 from a clinical study of lead program ONCOS-102 in patients with refractory malignant melanoma.
The second platform, TG peptides (TG), solely targets tumors that express mutated forms of the RAS protein. Mutations to this protein are common in many cancers and are known to drive aggressive disease progression and treatment resistance. There is a high unmet medical need for therapies that are effective against tumors that express these mutations. The TG platform's therapeutic potential stems from its ability to enable a patient's immune system to identify and then destroy tumors bearing any RAS mutations. In early 2017, key proof of concept data for the TG platform from a clinical study of TG01 in resected pancreatic cancer patients showed encouraging overall survival and will give guidance for the future clinical development of this platform.
Targovax's development pipeline has three novel therapeutic candidates in clinical development covering six indications. Both platforms are protected by an extensive portfolio of IP and know-how and have the potential to yield multiple product candidates in a cost-effective manner.
