GTX-102 is the first Angelman syndrome therapeutic candidate to receive PRIME designation Phase 1/2 study fully enrolled; expansion data expected in first half of 2024 NOVATO, Calif., Feb. 05, 2024 (GLOBE NEWSWIRE) -- Ultragenyx Pharmaceutical Inc. (NASDAQ: RARE) today announced that the European Medicines Agency (EMA) has granted Priority Medicine (PRIME) designation to GTX-102 for the treatment of Angelman syndrome (AS). GTX-102 is an investigational antisense oligonucleotide delivered via intrathecal administration and is designed to target and inhibit expression of UBE3A antisense transcript (UBE3A-AS). The EMA granted this designation in response to compelling early clinical data from the extension cohorts in the Phase 1/2 study of GTX-102 demonstrating clinically meaningful improvements in several neurodevelopmental domains including cognition, receptive communication and gross motor skills in individuals with Angelman syndrome. "By granting PRIME designation, the EMA is recognizing the potential for GTX-102 to address the critical need for new treatments for children and families impacted by Angelman syndrome in the EU,” said Eric Crombez, M.D., chief medical officer at Ultragenyx. “Our team is working with urgency on the development of GTX-102 for Angelman syndrome and looks forward to working closely with regulators in the U.S. and EU to bring this innovative treatment to patients.” PRIME designation is granted by the EMA to provide early and proactive support to developers of promising medicines that may offer a major therapeutic advantage over existing treatments or benefit to patients without treatment options. These medicines are considered priority medicines by the EMA, whose aim is to optimize development plans and speed up evaluations so these medicines that address significant unmet medical needs can reach patients faster. About the Phase 1/2 study The Phase 1/2, open-label, multiple-dose, dose-escalating study is evaluating the safety and tolerability of GTX-102 administered by intrathecal (IT) injection to pediatric patients with Angelman syndrome with a genetically confirmed diagnosis of full maternal UBE3A gene deletion. The study is also assessing clinical response as measured by a panel of efficacy assessments for the functional domains impacted in Angelman syndrome. Patients in the earlier extension cohorts (Cohorts 4-7) of the study have moved into long-term maintenance dosing, and the study has completed enrollment for the new expansion cohorts to verify the GTX-102 dose range and treatment regimen that will be used in the Phase 3 program. About Angelman Syndrome Individuals with Angelman syndrome have developmental delay, balance issues, motor impairment and debilitating seizures. Some individuals with Angelman syndrome are unable to walk and most do not speak. Anxiety and disturbed sleep can be serious challenges in individuals with Angelman syndrome. Although individuals with Angelman syndrome have a normal lifespan, they require continuous care and are unable to live independently. Angelman syndrome is not a degenerative disorder, but the loss of the UBE3A protein expression in neurons results in abnormal communications between neurons. Angelman syndrome is often misdiagnosed as autism or cerebral palsy. There are no currently approved therapies for Angelman syndrome; however, several symptoms of this disorder can be reversed in adult animal models of Angelman syndrome suggesting that improvement of symptoms can potentially be achieved at any age.
