Dragonfly Therapeutics Announces Encouraging Early Results from the Phase 1 for DF5112, its CCR6-Targeting Molecule

DF5112 provides deep Th17 and B cell depletion in IV cohort and is now dosing its Phase 1 subcutaneous cohorts.

WALTHAM, Mass., May 18, 2026 /PRNewswire/ — Dragonfly Therapeutics, a clinical-stage biopharmaceutical company pioneering novel immunotherapies, today announced that the first healthy volunteers have been successfully dosed subcutaneously (SC) with its CCR6-targeting molecule, DF5112. This milestone follows the successful completion of the intravenous (IV) dosing phase which demonstrated DF5112’s strong depletion of both Th17 and B cells.

By targeting CCR6 to therapeutically deplete both Th17 cells and B cells — two key immune cell populations implicated in a range of autoimmune and inflammatory diseases — DF5112 offers the potential for distinctively appealing immunomodulatory activity.

“We are enthusiastic about the early results from our CCR6 program,” said Bill Haney, Dragonfly’s CEO. “We are excited to be advancing DF5112 for patients suffering from autoimmune diseases ranging from psoriatic arthritis and Sjögren’s, to systemic sclerosis and hidradenitis suppurativa.”

DF5112’s Phase 1 (NCT07232121) is a double-blind, randomized, placebo-controlled study to evaluate safety, tolerability, pharmacokinetics, immunogenicity and pharmacodynamics of DF5112 in healthy adult participants.
