PHILADELPHIA, Aug. 22, 2023 (GLOBE NEWSWIRE) -- Cabaletta Bio, Inc. (Nasdaq: CABA), a clinical-stage biotechnology company focused on developing and launching the first curative targeted cell therapies for patients with autoimmune diseases, today announced that it has entered into certain work orders relating to Good Manufacturing Practice (GMP) manufacturing under its existing master services agreement with WuXi Advanced Therapies (WuXi ATU), a global Contract Testing, Development and Manufacturing Organization (CTDMO). As part of the agreement, WuXi ATU will serve as a cell processing manufacturing partner for the planned global clinical development of CABA-201 in multiple indications, including potential late-stage clinical trials and commercial readiness activities for CABA-201.

“We have had a successful collaboration with WuXi ATU over the past two years for the GMP compliant production of novel cell therapies. Based on this initial collaboration, we chose to expand our partnership to include WuXi ATU as a manufacturer for our CABA-201 clinical programs,” said Gwendolyn Binder, Ph.D., President of Science and Technology of Cabaletta. “WuXi ATU’s dedicated production capacity for CABA-201 supports our planned global expansion and commercial preparedness efforts and will enable us to dose patients in multiple clinical trials with separate parallel cohorts, while maintaining a capital-efficient manufacturing strategy.”

Under the terms of the agreement, WuXi ATU will provide GMP manufacturing of CABA-201, a 4-1BB-containing fully human CD19-CAR T cell investigational therapy, to support any of Cabaletta’s planned clinical trials, including the previously announced separate Phase 1/2 clinical trials of CABA-201 for the treatment of patients with systemic lupus erythematosus and idiopathic inflammatory myopathies, or myositis. In addition, WuXi ATU will continue to serve as the Company’s cell processing manufacturing partner for the MusCAARTes Phase 1 clinical trial of MuSK-CAART.
