FDA Priority Reviews Signal Shifts in Cancer, Tourette, and PAH Care
Accelerated FDA filings advance non-surgical cancer immunotherapy, Teva's pediatric Tourette drug, and United Therapeutics' oral PAH pill.
Health
Priority FDA review for GSK's immunotherapy promises to replace organ-removal surgery with targeted drugs for specific rectal cancer patients — setting up a new standard of non-surgical care.
BackgroundMismatch repair-deficient (dMMR) rectal cancers represent a distinct molecular subset of tumors that are highly responsive to immune checkpoint inhibitors. Standard treatment historically required invasive organ-removal surgery, radiation, and systemic chemotherapy that left patients with permanent functional changes.
- The FDA assigned a target action date under its priority review program, accelerating potential approval to early 2027 and shortening standard review timelines by four months.
- Phase 2 AZUR-1 trial data in 154 patients demonstrated a 100% complete clinical response rate without surgical intervention, eliminating organ-removal procedures for all trial participants.
- An approval would establish Jemperli as the first frontline non-surgical immunotherapy option for dMMR rectal cancer, reshaping long-standing oncology treatment protocols.

Teva is nearing regulatory approval for a novel Tourette drug — giving pediatric patients their first new pharmacological mechanism in 50 years without severe metabolic side effects.
BackgroundTourette syndrome is a neurodevelopmental disorder characterized by involuntary motor and vocal tics that typically emerge during early childhood. Existing approved treatments rely on D2 dopamine receptor blockade, which frequently causes debilitating side effects such as severe weight gain, metabolic dysfunction, and movement disorders.
- The FDA scheduled its target decision date for late Q1 2027 under Priority Review designation, expediting the standard ten-month regulatory review cycle.
- Phase 3 clinical trial results revealed pediatric patients treated with ecopipam experienced a 53% lower risk of tic relapse compared to those receiving placebo.
- By selectively targeting D1 dopamine receptors instead of D2, ecopipam avoids the heavy sedation and weight gain that traditionally force families to discontinue Tourette medications.
Health
United Therapeutics is expanding oral treatment options for pulmonary hypertension — replacing invasive infusion pumps with daily pills that significantly reduce disease progression.
BackgroundPulmonary arterial hypertension is a progressive vascular disorder characterized by high blood pressure in lung arteries that eventually leads to right-sided heart failure. Potent prostacyclin pathway therapies have long served as essential treatment pillars but historically required invasive continuous intravenous or subcutaneous infusion pumps.
- The FDA set a target PDUFA action date of June 24, 2027 to complete its review of the oral ralinepag filing.
- Phase 3 ADVANCE OUTCOMES data showed a statistically significant 55% reduction in risk of clinical disease worsening compared to placebo in patients receiving background therapy.
- A once-daily oral tablet eliminates the infection risks and lifestyle burdens associated with permanent catheter pumps, broadening access to prostacyclin therapy.
