Cabaletta Bio, Inc.

Cabaletta Bio, Inc. is a clinical-stage biotechnology company developing engineered T-cell therapies for autoimmune diseases. Its core platform, CABA, is designed to selectively eliminate disease-causing B cells and plasma cells, with lead programs such as rese-cel being studied in indications including pemphigus vulgaris, myositis, systemic lupus erythematosus, generalized myasthenia gravis, systemic sclerosis, and related autoimmune disorders. The company has not yet generated product revenue and remains focused on advancing clinical trials, regulatory interactions, and manufacturing readiness. Cabaletta is also building a commercial-scale manufacturing strategy through CDMO partnerships and potential internal capabilities to support future supply if its programs are approved.

01
Advance lead clinical programsshort-term

Clinical proof-of-concept is the main value driver for a pre-revenue biotech and is required for any regulatory path.

02
Build scalable manufacturing capabilityshort-term

Cell therapy commercialization depends on reliable, compliant, and scalable supply.

03
Broaden platform applicabilitymedium-term

Multiple autoimmune indications can diversify clinical risk and increase the long-term commercial opportunity.

04
Maintain financing flexibilityshort-term

The company expects continued cash burn before any product revenue and needs capital to fund trials and manufacturing.
