Compugen to hold 2nd Quarter Conference Call August 7, 2013

TEL AVIV, Israel I August 5. 2013 I Compugen Ltd. (NASDAQ: CGEN) announced today the signing of a collaboration and license agreement for the research, development, and commercialization of antibody-based therapeutics for cancer immunotherapy against two novel Compugen discovered immune checkpoint regulators. Under the terms of the agreement, Bayer HealthCare (Bayer) and Compugen will jointly pursue a preclinical research program. Subsequently, Bayer will have full control over further development and have worldwide commercialization rights for potential cancer therapeutics.

Under the agreement Compugen will receive an upfront payment of USD 10 million, and is eligible to receive over USD 500 million in potential milestone payments for both programs, not including milestone payments of up to USD 30 million associated with preclinical activities. Additionally, Compugen is also eligible to receive mid to high single digit royalties on global net sales of any resulting products under the collaboration.

“Bayer is committed to translating the science of cancer research into effective therapies helping people affected by cancer live longer and improve their quality of life,” said Prof. Andreas Busch, Member of the Bayer HealthCare Executive Committee and Head of Global Drug Discovery. “Antibody-based immunotherapies are promising approaches in oncology which can stimulate the body’s own immune cells to fight cancer cells. Immunotherapy is one of our focus areas in oncology research. We are looking forward to expanding our portfolio in this area through partnering with Compugen.”

Anat Cohen-Dayag, Ph.D., President and CEO of Compugen, added, “We are very excited to initiate this collaboration with Bayer, a leading global life science company with a broadening oncology franchise, for the development of antibody-based cancer immunotherapies against these two promising novel immune checkpoint targets. In addition, we believe that the prediction and validation of these two targets, through the use of our broadly applicable predictive discovery infrastructure, provides additional validation for our long-term commitment to establishing this unique capability”.

The immunotherapy approach aims at combatting cancer by stimulating the body’s own immune cells. The tumor and its environment suppress the ability of cancer patients to develop an effective anti-tumor immune response and in this way protect both tumor growth and survival. Compugen has discovered two novel immune checkpoint regulators that potentially play a key role in immunosuppression. Researchers at Compugen are developing specific therapeutic antibodies that are geared to block the immunosuppressive function of these targets and to reactivate the patient’s anti-tumor immune response in order to fight cancer.

About Cancer Immunotherapy

Latest cancer immunotherapies have demonstrated impressive clinical benefit, even for end-stage patients with difficult-to-treat tumors such as metastatic melanoma and non-small cell lung cancer. Unlike conventional cancer therapies, which act by directly targeting the cancer cells, resulting often in only transient clinical responses as cancer cells become resistant, clinical responses to cancer immunotherapy tend to be durable, sometimes resulting in dramatic long term survival and absence of resistance or recurrences.

About Compugen

Compugen is a leading drug discovery company focused on therapeutic proteins and monoclonal antibodies to address important unmet needs in the fields of immunology and oncology. The Company utilizes a broad and continuously growing integrated infrastructure of proprietary scientific understandings and predictive platforms, algorithms, machine learning systems and other computational biology capabilities for the in silico (by computer) prediction and selection of product candidates, which are then advanced in its Pipeline Program. The Company’s business model includes collaborations covering the further development and commercialization of selected product candidates from its Pipeline Program and various forms of research and discovery agreements, in both cases providing Compugen with potential milestone payments and royalties on product sales or other forms of revenue sharing. In 2012, Compugen established operations in California for the development of oncology and immunology monoclonal antibody therapeutic candidates against Compugen drug targets.
