"The US Food and Drug Administration (USFDA) has issued a Complete Response letter (CRL) to the company's new drug application (NDA) for Elepsia XR," Sun Pharma Advanced Research Company (SPARC) had said in a statement on Friday.
"However, SPARC has now received a CRL from the USFDA rescinding its earlier approval, citing that the compliance status of the manufacturing facility was not acceptable on the date of approval," it said.
