Attovia Therapeutics, Inc.

We are a clinical-stage biopharmaceutical company developing next-generation biotherapeutics for immune-mediated diseases with high unmet need. Our lead pipeline candidates target commercially validated pathways and are designed through our ATTOBODY biologics platform to deliver improved treatments relative to the current standards of care. Leveraging our ATTOBODY platform, we have nominated three product candidates within our first two years, including one currently in the clinic, ATTO-1310. ATTO-1310 is an ATTOBODY-based therapeutic targeting interleukin-31 (IL-31) that completed dosing in a Phase 1 clinical trial in healthy volunteers (HVs) and patients in the first quarter of 2026. ATTO-2306 is an ATTOBODY-based bispecific targeting interleukin-13 (IL-13) and IL-31 that is in investigational new drug (IND)-enabling studies, and we expect to commence a Phase 1 clinical trial in the first half of 2027. Lastly, ATTO-1091 is our trispecific ATTOBODY-based Fc fusion protein that is designed to block TL1A, IL-23 and integrin a4ß7 simultaneously, and is currently in IND-enabling studies.
