In a controversial move, the U.S. FDA has given the green light for Forzinity, a costly drug aimed at treating Barth syndrome, despite data reviewers concluding its effects weren't markedly superior to a placebo. The decision on the drug, priced at nearly $800,000 annually, came after much debate.

FDA's documents reveal that the approval of Stealth Biotherapeutics' elamipretide—marketed as Forzinity—was driven by an urgent unmet need in patients, albeit with reservations about its efficacy. The disease, affecting around 150 U.S. males, often results in severe infancy heart failure.

The approval followed advocacy pressures from lawmakers and patient groups, with Forzinity marking the first treatment of its kind for Barth syndrome. However, internal disagreements within the FDA highlight ongoing tensions over balancing scientific evidence against patient demands for ultra-rare disease solutions.
