The Food and Drug Administration has approved , a rare condition that causes extremely painful reactions when skin is exposed to light, according to an FDA announcement.
This is the first treatment approved to help patients with this condition increase their exposure to light, according to the release.
Afamelanotide, administered in a subcutaneous implant, is a melanocortin-1 receptor (MC1-R) agonist, which “increases the production of eumelanin in the skin independent of exposure to sunlight or artificial light sources,” the release says.
Approval is based on a pair of parallel-group clinical trials that compared the number of hours spent in sunlight in the treatment and placebo groups. The first trial enrolled 93 patients; 48 received afamelanotide. The treated patients spent a median of 61 hours in total over 180 days in direct sunlight between 10 a.m. and 6 p.m. on days with no pain, compared with 41 hours for patients taking placebo.
The second trial assessed the total number of hours over 270 days spent outdoors between 10 a.m. and 3 p.m. on days with no pain for which “most of the day” was spent in direct sunlight. In this study, 38 patients treated with afamelanotide spent a median total of 6 hours, compared with 0.75 hours among the remaining 36 who were taking a placebo.
The most common side effects include implant site reaction, nausea, and oropharyngeal pain. The implant should be administered only by trained professionals. Because afamelanotide may cause skin darkening, it’s recommended that patients should undergo twice-yearly skin examinations. Patients are also encouraged to maintain sun protection measures to help prevent phototoxic reactions.
“Today’s approval is one example of the FDA’s ongoing commitment to encourage industry innovation of therapies to treat rare diseases, and work with drug developers to make promising new therapies available to patients as safely and efficiently as possible,” said Julie Beitz, MD, director of FDA’s Center for Drug Evaluation and Research Office of Drug Evaluation III in the FDA release.
