FDA Accepts Orasis Pharmaceuticals’ New Drug Application for CSF-1 for the Treatment of Presbyopia

Orasis Pharmaceuticals, an emerging ophthalmic pharmaceutical company focused on developing a unique eye drop to improve near vision for people with presbyopia, today announced that the US Food and Drug Administration (FDA) has accepted for review its New Drug Application (NDA) for investigational CSF-1 (low dose pilocarpine hydrochloride 0.4%). The FDA has assigned a Prescription Drug User Fee Act (PDUFA) goal date of October 22, 2023.

“We are encouraged by the acceptance of our NDA filing as we progress towards our mission of reshaping vision possibilities for the millions of people in the U.S. living with presbyopia, or blurry near vision,” said Elad Kedar, Chief Executive Officer of Orasis Pharmaceuticals. “We look forward to working with the FDA towards approval and commercial launch of CSF-1.”

The NDA is based on data from the Phase 3 NEAR-1 and NEAR-2 clinical trials, involving more than 600 patients, which evaluated the efficacy and safety of CSF-1. Both trials met their primary and key secondary endpoints on Day 8, achieving statistically significant 3-line or more gain in distance-corrected near visual acuity (DCNVA), and no loss of 1-line or more in distance visual acuity. The most common treatment-related adverse events of headache and instillation site pain occurred in only 6.8% and 5.8% of participants, respectively. Of all CSF-1 participants, only 2.6% reported moderate treatment-related adverse events. All other adverse events were mild.
