Though it’s been used off-label for more than three decades to treat cerebrotendinous xanthomatosis, Mirum Pharmaceuticals Inc.’s chenodiol gained an official U.S. FDA nod Feb. 21 as the first drug approved specifically for treating the rare autosomal recessive lipid storage disease.

As the flurry of executive orders continues to flow from the White House, leaving in its wake chaos and confusion across the overall health care sector, Tim Opler, managing director of the global health care group at investment firm Stifel, is taking the long view and urging the biopharma sector to continue focusing on innovation.

Snagging its second U.S. FDA approval since being spun out of Pfizer Inc. in 2017, Springworks Therapeutics Inc. is aiming to position Gomekli (mirdametinib), cleared for neurofibromatosis type 1-associated plexiform neurofibromas (NF1-PN) not amenable to complete resection, as a first-in-class drug for adults and potentially best-in-class option for children. The priority approval, which came after market close Feb. 11, more than two weeks ahead of the Feb. 28 PDUFA date, marks the second MEK1/2 inhibitor to hit the market for NF1-PN, a rare, genetic condition.

Touting its novel approach for treating glaucoma, Qlaris Bio Inc. reported promising top-line data from two phase II studies testing QLS-111 in patients with primary open-angle glaucoma and ocular hypertension, showing the drug met all primary and secondary endpoints, reducing intraocular pressure with a clean safety profile that could encourage patients to remain on treatment.

An effort two decades in the making, Vertex Pharmaceuticals Inc.’s suzetrigine gained U.S. FDA approval as the first drug targeting the NaV1.8 pain signal. Branded Journavx, the oral small molecule is cleared for use as a non-opioid option for treating moderate to severe acute pain.

In an indication that has proved difficult for biopharma to conquer, Regulus Therapeutics Inc. disclosed further positive data from its ongoing phase Ib study testing RGLS-8429 in autosomal dominant polycystic kidney disease and laid out its plans to move straight into a phase III trial later this year, with the potential for an accelerated U.S. approval.

What a difference 60 weeks can make. That’s the lesson Akero Therapeutics Inc. shared with the rollout of what executives called “unprecedented” data from the phase IIb Symmetry trial testing efruxifermin (EFX), its FGF21 receptor agonist, in patients with compensated cirrhosis due to metabolic dysfunction-associated steatohepatitis (MASH). While earlier findings had shown only a trend in improvement at 36 weeks, full 96-week results showed more than doubling of earlier effect size, hitting the primary endpoint and sending shares of Akero (NASDAQ:AKRO) up 97% to close Jan. 27 at $51.71.

Medexus Pharmaceuticals Inc. looks set for its U.S. launch of bifunctional alkylating agent treosulfan in the first half of 2025 following a long-awaited FDA approval of the drug, branded Grafapex, for use in combination with fludarabine as a preparative regimen for allogeneic hematopoietic stem cell transplantation (allo-HSCT) in adults and pediatric patients, 1 and older, with acute myeloid leukemia or myelodysplastic syndrome.

With positive data in hand from its phase IIb trial testing immunotherapy candidate OST-HER2 in osteosarcoma, OS Therapies Inc. anticipates a regulatory filing this year seeking accelerated approval from the U.S. FDA, putting the firm on track to receive a potentially profitable rare pediatric disease priority review voucher that could help fund further R&D work. Should OST-HER2 go on to win approval, it would mark the first new therapy in more than 40 years for osteosarcoma, an aggressive bone cancer characterized by high rates of metastases, often to the lungs, and disease recurrence.
