Once-Weekly TransCon® CNP (Navepegritide) Receives Positive CHMP Opinion for the Treatment of Achondroplasia in Children

Final European Commission decision expected during Q4 2026

COPENHAGEN, Denmark, Oct. 16, 2026 (GLOBE NEWSWIRE) -- Ascendis Pharma A/S (Nasdaq: ASND) today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion recommending marketing authorization for once-weekly TransCon CNP (navepegritide) in the European Union for the treatment of achondroplasia in children two years of age and older whose epiphyses are not closed. The final European Commission (EC) decision on Ascendis Pharma’s Marketing Authorisation Application (MAA) is expected during Q4 2026.

“We are pleased to receive this positive opinion reflecting the unique profile of TransCon CNP,” said Jan Mikkelsen, President and Chief Executive Officer at Ascendis Pharma. “With a highly favorable response from the achondroplasia community to its differentiated profile, TransCon CNP remains a foundational product in our growth disorder portfolio, positioned to support our Vision 2030 objectives.”

CHMP adopted its positive opinion following its review of the MAA for TransCon CNP, which included clinical data from three randomized, double-blind, placebo-controlled clinical trials and up to three years of open-label extension data. The pivotal ApproaCH Trial data is available in JAMA Pediatrics.ⁱ

TransCon CNP was designated as an orphan medicine during its development. EMA will now review the information available to date to determine if the orphan designation can be maintained.

If authorized by the EC, Ascendis expects its first EU launch of TransCon CNP under the brand name YUVIWEL^® to be in Germany during Q1 2027.

About TransCon CNP
TransCon CNP is a prodrug of C-type natriuretic peptide (CNP) administered once weekly, designed to provide continuous exposure of active CNP to receptors on tissues throughout the body to counteract the overactive FGFR3 signaling in achondroplasia. It is the only approved therapy to provide continuous systemic exposure to active CNP over the weekly dosing interval. In February 2026, TransCon CNP was approved by the U.S. Food & Drug Administration (FDA) under the trade name YUVIWEL^® to increase linear growth in pediatric patients 2 years of age and older with achondroplasia with open epiphyses. A final decision by the European Commission is anticipated in the fourth quarter of 2026.

About Achondroplasia
Achondroplasia is a rare genetic condition arising from a systemic fibroblast growth factor receptor 3 (FGFR3) variant that leads to an imbalance in the effects of the FGFR3 and CNP signaling pathways, estimated to affect more than 250,000 people worldwide. While historically considered a bone growth disorder, the FGFR3 variant seen in achondroplasia is expressed in tissues throughout the body, causing serious muscular, neurological, and cardiorespiratory complications in addition to skeletal dysplasia. Medical complications of achondroplasia vary across different stages of life. Throughout infancy and childhood, observed complications include spinal abnormalities, enlarged brain ventricles, impaired muscle strength and stamina, hearing deficits and chronic ear infections, upper airway obstructions, sleep-disordered breathing, hip problems, leg bowing, and chronic pain; many of these persist or worsen in adulthood. These medical complications can affect physical well-being and quality of life, and may be impacted by a range of individual, clinical, and social factors. Some individuals with achondroplasia require multiple procedures and surgeries to address specific functional or anatomical concerns.
