•Participants will be randomized (1:1) between EryDex or placebo and treatment will consist of six infusions scheduled once every 21 to 30 days. The primary efficacy endpoint will be measured by the change from baseline to last visit completion in a rescored modified International Cooperative Ataxia Rating Scale (RmICARS) compared to placebo as per the SPA agreement with the FDA.
Pipeline and Corporate Updates
•Participation at scientific congresses, including a poster presentation of safety data from the previously completed ATTeSt study at the 53rd Child Neurology Society Annual Meeting. Quince is also sponsoring and participating at the 2024 International Congress for Ataxia Research in November 2024 with two poster presentations, including growth and bone mineral density in patients with A-t treated with EryDex, and an analysis of the International Cooperative Ataxia Rating Scale (ICARS) subcomponent scores in patients with A-t.
•Generating Phase 2 clinical trial study designed to evaluate EryDex for the potential treatment of patients with Duchenne muscular dystrophy (DMD), including those with corticosteroid intolerance, who represent the
majority of the DMD population. Quince plans to initiate a DMD Phase 2 study in 2025, which the company expects to conduct utilizing capital efficient study approaches.
•Completed evaluation process of other potential rare disease indications beyond A-t and Duchenne muscular dystrophy for EryDex where chronic corticosteroid treatment is – or has the potential to become – a standard of care, if there were not corticosteroid-related safety concerns. The prioritized list of other potential rare disease targets under consideration includes: 1) autoimmune hepatitis, 2) dermatomyositis, 3) pemphigus vulgaris, 4) Hashimoto's encephalopathy, 5) Becker muscular dystrophy, 6) pediatric lupus, 7) juvenile idiopathic arthritis, 8) myasthenia gravis, 9) limb-girdle muscular dystrophy, 10) chronic inflammatory demyelinating polyradiculoneuropathy, and 11) pulmonary sarcoidosis.
