Poster, the California-based biotech company, has recently entered into a co-development agreement with Pfizer, one of the largest pharmaceutical companies in the world. The collaboration aims to advance Poster`s cancer immunotherapy program, PSR-SI-007, which is currently in the preclinical stage.

Under the terms of the agreement, Pfizer will make an initial payment of $10 million to Poster, followed by additional payments upon the achievement of predefined development and regulatory milestones. In exchange, Pfizer will have an exclusive option to acquire the global rights to PSR-SI-007.

The co-development agreement between Poster and Pfizer highlights the growing interest in cancer immunotherapy, a field that has shown tremendous promise in recent years. Cancer immunotherapy works by harnessing the power of the immune system to recognize and destroy cancer cells. This approach has the potential to be more effective and less toxic than traditional chemotherapy, which indiscriminately kills all dividing cells in the body.

Poster`s PSR-SI-007 is a novel approach to cancer immunotherapy that targets a specific type of immune cell called a myeloid-derived suppressor cell (MDSC). MDSCs are known to play a key role in suppressing the immune system and promoting tumor growth. By targeting and neutralizing MDSCs, PSR-SI-007 may be able to enhance the immune response against cancer cells.

Pfizer`s expertise in drug development and commercialization, combined with Poster`s innovative approach to cancer immunotherapy, makes for a promising partnership. If successful, PSR-SI-007 has the potential to provide a new treatment option for cancer patients and advance the field of immunotherapy.
