Sun Pharma Advanced Research Company (SPARC) announced that the US FDA has not raised any concerns regarding the efficacy or safety of its glaucoma drug candidate PDP-716. The regulatory delay stems solely from inspection issues at a third-party API facility, with no additional clinical trials required.
Sun Pharma Advanced Research Company Ltd (SPARC) has received a Complete Response Letter (CRL) from the US Food and Drug Administration (FDA) for its New Drug Application (NDA) of PDP-716, a once-daily formulation of brimonidine tartrate for glaucoma treatment. Importantly, the FDA did not raise any issues related to the drug’s clinical efficacy or safety.
The CRL was issued due to inspection findings at a third-party Active Pharmaceutical Ingredient (API) manufacturing facility. SPARC confirmed that no new clinical data or trials have been requested and that it is working closely with its partner Visiox Pharma and the FDA to address the manufacturing concerns and resubmit the NDA promptly.
Key highlights from the announcement include
-
FDA’s CRL cited only manufacturing inspection issues, not clinical deficiencies.
-
No concerns were raised regarding PDP-716’s efficacy or safety profile.
-
No additional clinical trials or data submissions are required at this stage.
-
SPARC is collaborating with Visiox and the third-party API manufacturer to resolve the inspection findings.
The company remains committed to bringing PDP-716 to market as a once-daily treatment for glaucoma.
