A novel alpha-active IL-2-Fc has expanded therapeutic index and robust monotherapy efficacy in mouse cancer models and strong synergy with PD-1 blockade
(SITC 2024)
- P1 | "Aldesleukin is an approved recombinant human IL-2; however, its short half-life, requirement for 5 days of hospitalization per cycle, and high toxicity [eg, cytokine related syndrome (CRS), capillary leak syndrome (CLS)] severely limit its clinical use. DF6215 is currently being evaluated in a Phase 1/1b clinical trial in patients with advanced solid tumors (NCT06108479). Ethics Approval All mouse studies were carried out according to protocols established by Explora BioLabs/CRADL IACUC committee."

Dragonfly Therapeutics to Present Preclinical Data on Clinical-Stage DF6215, its Engineered IL-2R alpha-active Agonist, and DF9001, its EGFR-targeting TriNKET, at the Society for Immunotherapy of Cancer (SITC) Annual Conference
(PRNewswire)
- "Data show that Dragonfly's DF6215 IL-2 cytokine drives greater therapeutic benefit in vivo than non-alpha IL-2, with no evidence of capillary leak syndrome or cytokine release syndrome. In addition, DF6215 synergizes with PD-1 blockade cancer treatment in the 'cold' B16F10 melanoma tumor model, without adding toxicity. 'DF6215 is a differentiated IL-2, specifically tuned to potently stimulate anti-tumor CD8 T cells and NK cells without incurring counterproductive Treg expansion or VLS,' said Ann Cheung, Chief Scientific Officer of Dragonfly Therapeutics....Data show superior anti-tumor activity via EGFR signal inhibition compared to cetuximab in a xenograft mice model, and that DF9001 induces potent in vivo efficacy via immune effector cells, even in cancer models not dependent on EGFR signaling."

Dragonfly Therapeutics Initiates Phase 1/1b Study of its IL-2 Immunotherapy in Patients with Advanced Solid Tumors
(BioSpace)
- "'DF6215's therapeutic potential is particularly compelling,' said Dr. Benedito A. Carneiro, MD...'Dragonfly's IL-2 preclinical package shows strong anti-tumor activity in cold and hot tumor models and a favorable therapeutic window in cyno, with no signs of Vascular Leak Syndrome or Cytokine Release Syndrome - which we believe powerfully differentiates DF6215 from historic IL-2 drug candidates.'"
