• Data demonstrate significant improvements in well-being and physical functioning compared to placebo in patients treated for 1 year with TransCon CNP at the pivotal 100µg/kg/week dose
• Improvements could not be explained by changes in linear growth only, supporting a potential additional direct treatment effect of TransCon CNP beyond linear growth
COPENHAGEN, Denmark, June 24, 2024 (GLOBE NEWSWIRE) -- Ascendis Pharma A/S (Nasdaq: ASND) today announced the oral presentation of data from its Phase 2 ACcomplisH Trial of TransCon CNP (navepegritide) in children aged 2 to 10 years old with achondroplasia by Ravi Savarirayan, M.D., Murdoch Children's Research Center (Australia), during ICCBH 2024, the International Conference on Children's Bone Health being held in Salzburg, Austria.
The data showed that patients treated for one year at the pivotal 100µg/kg/week dose demonstrated significant improvements in well-being and physical functioning compared to placebo. These improvements could not be explained by changes in linear growth only, supporting a potential additional direct treatment effect of TransCon CNP beyond linear growth.
"Once-weekly TransCon CNP has demonstrated a positive impact on linear growth with a favorable safety profile, as well as benefits beyond growth," said Dr. Savarirayan. "As the first investigational pharmaceutical treatment for achondroplasia to demonstrate statistically significant improvements compared to placebo in health-related quality of life measures, TransCon CNP at the pivotal dose has potential to meet the need for a treatment addressing the health and quality-of-life complications of this condition."
TransCon CNP is an investigational prodrug of C-type natriuretic peptide (CNP) administered once weekly, designed to provide sustained release of active CNP. ACcomplisH is a Phase 2, multicenter, randomized, double-blind, placebo-controlled, dose-escalation trial of once-weekly TransCon CNP versus placebo in 57 children with achondroplasia (aged 2-10 years old). Patients were randomized 3:1 to receive TransCon CNP across 4 dose-escalation cohorts or placebo for 52 weeks, after which participants could receive TransCon CNP in an ongoing open-label extension at the 100µg/kg/week dose. Health-related quality of life assessments compared 52-week results from patients whose initial TransCon CNP dose was 100µg/kg/week (the pivotal trial dose) with results from the pooled placebo group in the randomized period. Of the 57 participants, 56 continue with open-label treatment.
Statistically significant improvements were observed for various exploratory endpoints including Daily Living Functioning (p=0.047; n=16; 13 [treated;placebo]) and Emotional Well-Being (p=0.045; n=13;9) domains of the Achondroplasia Child Experience Measure-Impact (ACEM) assessment, and the SF-10 Physical Summary among participants 5 years of age or older (p=0.002; n=9;5). Growth across the full trial population (n=57) on TransCon CNP at the 100µg/kg/week dose for 52 weeks was consistent with results from this dose cohort during the randomized period.
No new safety signals were observed, and no serious adverse events related to the study drug were reported. Most treatment-emergent adverse events (TEAEs) were Grade 1-2, with a low frequency of injection site reactions.
