Earlier this month, the US FDA had revoked Ranbaxy’s six-month exclusivity for Nexium and Valcyte. The exclusivity period in the US market could have added about $200 million to Ranbaxy’s kitty.
“FDA has no power to correct an alleged mistake it made six years ago,” Ranbaxy said in the suit filed last week. On Nexium’s exclusivity, the US FDA had told this newspaper that FDA had rescinded a tentative approval under “rare circumstances”.
In the lawsuit, Ranbaxy said the US FDA’s move was arbitrary, capricious, contrary to law and in violation of constitutional rights. It also exceeded the agency’s statutory authority, the company added. “The agency issued its decision with no prior notice to Ranbaxy. It gave Ranbaxy no opportunity to comment on the issues raised. And, the agency had no power to issue its decision,” the lawsuit said.
The US FDA had barred Ranbaxy's manufacturing units in India to sell products in the US market, which led to substantial losses for the company, in the process of being acquired by Sun Pharma.
Nexium, one of Astrazenca's major drugs, went off patent in May this year; Roche's Valcyte went off patent in 2010.
Ranbaxy shares on Tuesday declined two per cent from their previous close on BSE to end at Rs 628.75 apiece. Angel Broking has said while the company's move is one of the first of this kind, the outcome would be vital for Ranbaxy, as the drugs concerned were expected to record good revenue and profitability for the company. Ranbaxy has been facing rough weather for some time. Recently, it agreed to settle litigation regarding its participation in Texas Medicaid, the US federal-state healthcare programme for those with low incomes. The settlement deal was worth about $40 million. In May last year, the company had paid a penalty of $500 million to the US Department of Justice, after pleading guilty to felony charges related to drug safety and misrepresenting data to gain approvals.
