The data showed strong efficacy across multiple autoimmune conditions: 7/8 myositis patients achieved meaningful responses, all SLE patients without nephropathy reached remission, and both scleroderma patients demonstrated significant skin improvements. Notably, these responses were achieved while patients discontinued immunomodulators and steroids. Safety data from 18 patients showed 94% had either no or Grade 1 CRS, and 89% had no ICANS. The company is advancing its RESET clinical program with 51 patients enrolled and 24 dosed across their network.

Cabaletta Bio (NASDAQ: CABA) has announced plans for a 2027 BLA submission for rese-cel in myositis following FDA alignment. The company received RMAT designation for rese-cel in treating myositis, a severe autoimmune disease affecting 80,000 U.S. patients. The RESET-Myositis trial will include two registrational cohorts of ~15 patients each: one for dermatomyositis/antisynthetase syndrome and another for immune-mediated necrotizing myopathy. The primary endpoint will use the total improvement score (TIS) within 26 weeks of rese-cel infusion. Currently, 44 patients are enrolled and 23 dosed across the RESET program. The company has $131.8M cash as of March 2025, funding operations into H1 2026. New clinical data will be presented at EULAR 2025 Congress in June.

Cabaletta Bio (NASDAQ: CABA) has reported its Q4 and full year 2024 financial results. The company is enrolling approximately one patient per week across its RESET™ clinical program, with 33 patients enrolled across 56 active clinical sites in the U.S. and Europe as of March 14, 2025.

Key highlights include:

• FDA meeting planned for 1H25 to align on myositis registrational trial designs
• Cash position of $164.0 million as of December 31, 2024, providing runway into 1H26
• Three oral presentations on rese-cel planned for EULAR 2025 Congress in June

In clinical developments, the company reported positive responses across multiple indications: three out of four SLE patients achieved DORIS remission, the first lupus nephritis patient achieved complete renal response, and dermatomyositis patients showed improvement. However, one systemic sclerosis patient experienced a grade 3 ICANS toxicity event, which resolved following treatment.

Cellares and Cabaletta Bio have successfully completed their Technology Adoption Program (TAP) for manufacturing rese-cel using the Cell Shuttle™ platform. The collaboration demonstrates the capability of Cellares' IDMO Smart Factory to automate and scale manufacturing for Cabaletta's clinical-stage CAR T program targeting autoimmune diseases.

The TAP successfully achieved automated, concurrent production of multiple rese-cel batches on a single Cell Shuttle. The platform performed all unit operations automatically, including cell isolation, enrichment, gene editing, activation, and expansion, meeting predefined quality requirements.

This partnership could enable Cabaletta Bio to meet global patient demand across multiple autoimmune conditions, including:

• Myositis (~70,000 US patients)
• Scleroderma (~90,000 US patients)
• Lupus nephritis (~100,000 US patients)

Through Cellares' network of planned global IDMO Smart Factories in the US, Europe, and Japan, the collaboration aims to reduce costs and enable rapid technology transfer for global expansion of rese-cel manufacturing.
