Dinesh Thakur says he waved the red flag only after Ranbaxy didn't respond to his concerns.
US drug maker Merck & Co has called off its two-year-old research alliance with India's largest drug company, Ranbaxy. Ranbaxy and Merck's wholly-owned Indian subsidiary, MSD, confirmed the development, but declined to provide further details.
US drug maker Merck & Co has terminated its nearly two-year-old alliance with Ranbaxy Laboratories to develop anti-infective medicines, which could have fetched the Indian firm $100 million over a period of five years.
The US Drug maker requested the court to pass an order to restrain DRL from commercially manufacturing, using, offering for sale, selling, marketing, distributing, or importing DRL's generic paricalcitol injectable products prior to the expiration of said patents.
The combined sales of the branded versions of the products in the US is about $3.5 billion.
The founders of Gland Pharma, led by Ravi Penmetsa, and KKR, together own 96 per cent of the company.
A new logo, colour and tagline were unveiled last month.
