India For Immediate Release Sun Pharma update on ANDA for generic Effexor XR® Mumbai, November 27, 2008: Sun Pharmaceutical Industries Ltd. (Reuters: SUN.BO, Bloomberg: SUNP IN, NSE: SUNPHARMA, BSE: 524715) announced that the USFDA has granted Osmotica’s Citizen Petition regarding venlafaxine extended release tablets. In this petiti on, USFDA was requested to refrain from approving any pending Abbreviated New Drug Application (ANDA) for such tablets that cited Wyeth’s Effexor XR® capsules as the reference drug. Sun Pharma had previously filed an ANDA with multiple para IV certifications for generic venlafaxine extended release tablets, bio-equivalent to Effexor XR® capsules . In a communication sent by USFDA to Osmotica, USFDA has concluded that now an ANDA for venlafaxine extended release tablets should reference Osmotica’s product and not Effexor XR®. Additionally, with such amendments to a pending ANDA not being permitted as per USFDA, it has advised the Company to submit a new ANDA if it wishes to pursue approval of an ANDA for venlafaxine extended release tablets.
