"As per the agreement, SPARC will licence Elepsia XRTM (Levetiracetam Extended Release tablets) to a wholly-owned subsidiary of Sun Pharma for the US market. SPARC will receive an up-front payment of USD 10 million from Sun Pharma," SPARC said in a BSE filing.
"The licensing of Elepsia XRTM is a step ahead in our desire to make it available for thousands of epilepsy patients taking multiple pills of Levetiracetam every day... If and when the USFDA reapproves the epilepsy XRTM application, Sun Pharma's significant US presence will help SPARC in commercialising this important product for patients in the US market," SPARC CEO Anil Raghavan said.
