Ascendis reports positive 3-year data for TransCon PTH in hypoparathyroidism

COPENHAGEN - Ascendis Pharma A/S (NASDAQ:ASND), a $10.6 billion biotech company whose shares have surged 33% over the past six months, announced new three-year data from its Phase 3 PaTHway Trial showing that TransCon PTH (palopegteriparatide) provided sustained benefits for adults with hypoparathyroidism regardless of disease cause. According to InvestingPro data, the company maintains an impressive 85% gross profit margin despite being in its growth phase.

According to data presented at the ENDO 2025 conference in San Francisco, patients completing 156 weeks of treatment showed improvements in biochemical markers, kidney function, and quality of life measures.

The trial retention rate was high, with 89% of the original 82 participants completing the 3.5-year study. At Week 156, 88% of patients maintained normal albumin-adjusted serum calcium levels, while 96% no longer required conventional therapy, defined as taking less than 600 mg/day of calcium and no active vitamin D.

Kidney function improvements were maintained through Week 156, with mean estimated glomerular filtration rate (eGFR) increasing by 8.76 mL/min/1.73 m² across all participants. Patients with compromised kidney function at baseline (eGFR

"These responses, including normalization of skeletal dynamics with significant and clinically meaningful improvements in kidney function, demonstrate the long-term benefits of this treatment option for the vast majority of adults with hypoparathyroidism," said Aimee Shu, Executive Vice President and Chief Medical Officer at Ascendis Pharma.

The treatment was generally well-tolerated with no new safety concerns identified during the extended treatment period. Most treatment-emergent adverse events were mild or moderate, with no serious adverse events related to the study drug. This positive development aligns with growing analyst optimism, as InvestingPro reports three analysts have recently revised their earnings expectations upward for the upcoming period.
