CRANBURY, N.J., Aug. 5, 2020 /PRNewswire/ -- Palatin Technologies, Inc. (NYSE American: PTN), a specialized biopharmaceutical company developing first-in-class medicines based on molecules that modulate the activity of the melanocortin and natriuretic peptide receptor systems, today announced completion of enrollment of its Phase 2 study with PL9643 for the treatment of dry eye disease (DED).
After delaying enrollment of new patient groups due to the COVID-19 pandemic, Palatin reinitiated enrollment in its PL9643 Phase 2 clinical study in subjects with dry eye disease last month. With enrollment completed, data readout is targeted for the fourth quarter of calendar year 2020.
"We are pleased to complete enrollment in this Phase 2 study. We believe that, if approved, PL9643's potentially quick onset to efficacy and favorable tolerability and safety profile may provide a viable treatment option to the significant percentage of patients not refilling their prescriptions for some DED drugs after their initial use," commented Carl Spana, Ph.D., President and CEO of Palatin.
The Phase 2 study is a multi-center, randomized double-masked and placebo-controlled study evaluating the efficacy and safety of PL9643 ophthalmic solution (topical eye drops) compared to placebo for the treatment of the signs and symptoms of dry eye. The study is designed to enroll up to 150 participants at three sites in the US. Patients were randomized in a 1:1 ratio into two arms, PL9643 or placebo, and undergo 12-weeks of treatment. The two primary endpoints are inferior corneal fluorescein staining and ocular discomfort. There are several secondary and exploratory outcome measures as well. For more information about the study, including inclusion/exclusion criteria, a clinical trial synopsis can be found on clinicaltrials.gov (NCT04268069).
About Dry Eye Disease (DED)
Dry eye disease is a common inflammatory disease that, left untreated, can become extremely painful and lead to permanent damage to the cornea and vision. Dry eye disease affects the cornea and conjunctiva of the eye resulting in irritation, redness, pain, and blurred vision. It is estimated to affect over 30 million people in the United States. The disease is characterized by insufficient moisture and lubrication in the anterior surface of the eye, leading to dryness, inflammation, pain, discomfort, irritation, diminished quality of life, and in severe cases, permanent vision impairment. Existing therapy for dry eye disease is generally regarded as inadequate by many physicians and patients, and often requires weeks or months to demonstrate activity.
