Under the new agreement, it will advance leads beyond candidate selection to completion of clinical proof of concept. GSK thereafter will conduct further clinical development for each program and take resulting products through the regulatory approval process to final commercialization.The company could receive over $100 million in potential milestone payments for a product developed by it and subsequently launched by GSK in multiple indications and up to double digit royalties on worldwide net sales.

The agreement presents a unique opportunity to demonstrate the India centric advantages of high quality research and development to deliver value at the cutting edge. I believe the arrangement with GSK is path-breaking and acknowledges the higher level of R&D maturity prevalent today in our state-of-the art labs in India."Reflecting on the agreement, Pradip Bhatnagar, vice president (new drug discovery research), GlaxosmithKline said: "This is a win-win agreement for both companies. By collaborating with Ranbaxy's talented R&D team, GSK will be able to develop more products for patients faster and Ranbaxy will benefit from GSK's vast drug discovery and development experience."
