MNV-201 receives fast track, rare pediatric disease to treat Pearson Syndrome

On June 30, 2025, the FDA granted both fast track and rare pediatric disease designations to Minovia Therapeutics' investigational cell therapy MNV-201 for the treatment of Pearson Syndrome, a rare and life-threatening mitochondrial disorder.

MNV-201 uses the company’s proprietary Mitochondrial Augmentation Technology to deliver healthy mitochondria into a patient’s stem cells, with the aim of restoring cellular energy production and improving multi-organ function. The therapy is currently being evaluated in phase 2 clinical trials and has shown a favorable safety profile and early signs of benefit in growth, muscle strength, and hematologic stability.

FDA revises labeling on extended-release stimulants for ADHD to include weight loss risk

On June 25, 2025, the FDA announced forthcoming labeling changes for all extended-release stimulant medications used to treat attention-deficit/hyperactivity disorder (ADHD), adding warnings about increased risks of adverse events—particularly weight loss—in children under 6 years of age.

Although these medications are not FDA-approved for use in this age group, they are sometimes prescribed off label. Based on clinical trial data, the FDA found that younger children receiving extended-release amphetamine or methylphenidate had higher drug exposure and a greater risk of clinically significant weight loss—defined as a ≥10% drop in CDC weight percentile—compared to older children.

FDA notifies providers of safety-related changes to prescribing information of maralixibat, odevixibat

On June 27, 2025, the FDA updated the prescribing information for the IBAT inhibitors maralixibat (Livmarli) and odevixibat (Bylvay), adding new safety warnings related to hepatotoxicity and bleeding risks. The updates include a new contraindication for patients with prior or active hepatic events and emphasize bleeding risks tied to fat-soluble vitamin deficiency.

The changes stem from clinical trial data and postmarket reports that highlighted severe hepatic complications such as variceal hemorrhage and hepatic encephalopathy. The updated labels include recommendations for liver monitoring and criteria for treatment discontinuation.
