The European Medicines Agency (EMA) had in January suspended a number of medicines approved for sale in the EU which were based on clinical studies conducted by GVK Bio at its Hyderabad site.
The action flowed from findings from an inspection that allegedly red-flagged how GVK conducted studies at the Hyderabad site on behalf of marketing authorisation holders.
"The Commerce Ministry is internally analysing the issue. It is looking at the legal and WTO angle in it. Without gathering the complete information about the case, it will be difficult to discuss the matter even at a bilateral level with the EU," a government source said.
EMA's Committee for Medicinal Products for Human Use had looked at over 1,000 pharmaceutical forms and strengths of medicines studied at the GVK site.

After India voiced protest, the European Union members agreed not to seize Indian medicines passing through Europe.
