About Metastatic Melanoma
Melanoma is a type of skin cancer that begins in skin cells called melanocytes. As the cancer progresses and begins to spreads beyond the skin, such as to the lymphatic system (metastatic disease), melanoma becomes more difficult to treat. Given its occurrence in young individuals, the potential years of life lost to melanoma can be higher when compared with other cancers. Although melanoma is a rare form of skin cancer, it accounts for over 75% of skin cancer deaths. The American Cancer Society estimates that approximately 87,000 new melanoma cases and 10,000 deaths from the disease will have occurred in the United States in 2017. Additionally, the World Health Organization estimates that approximately 132,000 new cases of melanoma are diagnosed around the world every year.
About PISCES (Anti-PD-1 IL-12 Stage III/IV Combination Electroporation Study)/KEYNOTE-695
PISCES/KEYNOTE-695 is a global, multicenter phase 2b, open-label trial of intratumoral plasmid-encoded IL-12 (tavokinogene telseplasmid or "tavo") delivered by electroporation in combination with intravenous pembrolizumab in patients with stage III/IV melanoma who have progressed or are progressing on either pembrolizumab or nivolumab treatment. The Simon 2-stage study of intratumoral tavo plus electroporation in combination with pembrolizumab will enroll approximately 48 patients with histological diagnosis of melanoma with progressive locally advanced or metastatic disease defined as Stage III or Stage IV. The primary endpoint will be the Best Overall Response Rate (BORR).
About OncoSec Technology Access Program
The OncoSec GENESIS™ research generator was developed specifically for gene electro-transfer. It features customizable electroporation parameters for construct-specific optimization of expression, and it is the only in vivo electroporation device enabled with TRACE™ Technology (Tissue-Based, Real-Time Adaptive Control Electroporation.) TRACE™ technology incorporates an electrochemical tissue-sensing control system to automatically adjust pulse width and treatment duration in real time during the electroporation procedure. This feature enables tissue- and therapeutic-specific delivery optimization, maximizing uptake of the therapeutic while reducing unnecessary cell ablation or damage. In research models, GENESIS™ with TRACE™ has yielded higher and more consistent in vivo protein expression versus fixed-parameter electroporation, even in heterogeneous tissues.
Potential advantages of using GENESIS™ with TRACE™ for the objectives of animal immunization include cost savings versus recombinant protein administration, a shortened pre-immunization timeline relative to recombinant protein production, and display of the immunizing antigen in its native conformation. The latter benefit may be particularly relevant for certain therapeutic indications, including immuno-oncology, in which many key targets require functional agonism and/or structurally-complex therapeutic modalities such as multimeric forms. To date, OncoSec has generated multiple high-titer antibody libraries against immuno-therapeutic targets.
The OncoSec Technology Access Program makes OncoSec's electroporation technologies available to collaborators for preclinical research. Devices are available for intratumoral, intradermal, and intramuscular delivery. For more information, please contact firstname.lastname@example.org.
