COPENHAGEN, Denmark, June 07, 2022 (GLOBE NEWSWIRE) — Ascendis Pharma A/S (Nasdaq: ASND) today announced that its presentations at ENDO 2022 will include oral presentations of Phase 2 and Phase 3 data for its investigational product candidate TransCon PTH in adult hypoparathyroidism (HP). During the meeting, which will be held in-person and virtually June 11-14 in Atlanta, Dr. Aliya Khan, M.D., Clinical Professor of Medicine at McMaster University and Director of the Calcium Disorders Clinic at McMaster University Medical Center, will give a late-breaker oral presentation of Phase 3 PaTHway Trial data for TransCon PTH in adult HP.

“This is the first Phase 3 trial in adult hypoparathyroidism in which the majority of treated patients achieved real control of their disease – that is, normalization of serum calcium, independence from conventional therapy, and a more normal patient-reported quality of life,” said Dr. Khan. “Additionally, TransCon PTH was generally well-tolerated with no discontinuations related to study drug, and TransCon PTH-treated patients showed a mean decrease in 24-hour urine calcium excretion into the normal range. I am hopeful that, with these encouraging results, we are closer to changing the treatment paradigm for patients living with this under-recognized and often debilitating disease.”

An additional Ascendis oral presentation at ENDO 2022 will include a review of Phase 2 TransCon PTH long-term data by Dr. Bart Clarke, Professor of Endocrinology at Mayo Clinic, showing durable benefit for adult hypoparathyroidism patients treated with TransCon PTH through Week 84 of the Pathway Trial. Additionally, Ascendis posters will present new data showing the continued safety and efficacy of once-weekly TransCon hGH in children with growth hormone deficiency treated for 2.5 years in the EnliGHten Trial, and, for adults with growth hormone deficiency, new research showing low treatment rates, increased medical risks, and higher healthcare costs.

Ascendis will also host a Medical Affairs booth (#1515) at ENDO 2022, as well as a separate booth (#1415) and events showcasing SKYTROFA^® (lonapegsomatropin-tcgd), the company’s once-weekly treatment for pediatric growth hormone deficiency.

“ENDO is one of the largest endocrine health symposiums, and we are especially pleased this year to be providing a comprehensive review of data from our second consecutive successful Phase 3 trial,” said Jan Mikkelsen, Ascendis Pharma’s President and Chief Executive Officer. “Ascendis is deeply committed to developing products that deliver value for patients, payers and society, and we are honored to be able to partner with patients, physicians, and other specialists in our work to advance understanding and treatment of rare endocrine diseases.”
