In a joint statement on Friday, Sun Pharma and its research arm SPARC said the USFDA has approved its new drug application of Xelpros. It said the approval is from Sun Pharma's Halol (Gujarat) facility. Xelpros is used to reduce open-angle glaucoma or ocular hypertension. "Sun Pharma in-licensed XELPROS from SPARC in June 2015 and this approval will trigger a milestone payment to SPARC," the joint statement said. SPARC is also eligible for milestone payments and royalties on the commercialisation of Xelpros in the US, it added. \u201cApproval of XELPROSTM by USFDA is a significant milestone for SPARC. It is also a validation of our SMM technology which helps to solubilize drugs that have limited or no solubility thus eliminating the need for benzalkonium chloride (BAK)," said\u00a0Anil Raghavan, CEO, SPARC.
