Curadev, Roche ink research cancer immunotherapeutic collaboration

Wednesday, April 22, 2015

Curadev Pharma, headquartered in New Delhi, India, has entered into a research collaboration and exclusive license agreement with Roche for the development and commercialization of IDO1 and TDO inhibitors. The agreement covers the development of the lead preclinical immune tolerance inhibitor and a research collaboration with Roche’s research and early development organization to further explore the IDO and TDO pathways.

IDO1 (indoleamine-2, 3-dioxygenase-1) and TDO (tryptophan-2, 3-dioxygenase) are enzymes that mediate cancer-induced immune suppression. This mechanism is exploited by tumor cells as well as certain type of immune cells, limiting the anti-tumor immune response.  

Dual inhibition of the IDO1 and TDO pathways promises to maintain the immune response, prevent local tumor immune escape and potentially avoid resistance to other immunotherapies when used in combination, and could lead to new treatment options for cancer patients. Curadev’s preclinical lead-compound, a small-molecule that shows potent inhibition of the two rate-limiting enzymes in the tryptophan—to kynurenine metabolic pathways, has the potential for mono therapy as well as combination with Roche’s broad oncology pipeline and portfolio.

The agreement includes a research collaboration with Roche’s research and early development organization to further extend Curadev’s findings. Curadev will receive an upfront payment of $25 million and will be eligible to receive up to $530 million in milestone payments based on achievement of certain predetermined events and sales levels as well as escalating royalties potentially reaching double digits for the first product from the collaboration developed and commercialized by Roche. Curadev also would be eligible for milestones and royalties on any additional products resulting from the research collaboration. Roche will fund future research, development, manufacturing and commercialization costs and will also provide additional research funding to Curadev for support of the research collaboration.
