– Proof of mechanism for novel glyco-immune checkpoint inhibitor established with evidence of dose dependent desialylation and immune system activation –
– E-602 was well-tolerated across the entire dose range with no dose-limiting toxicities –
– Palleon to proceed with Phase 2 evaluation –
WALTHAM, MA, USA I April 18, 2023 IPalleon Pharmaceuticals, a clinical-stage company pioneering glyco-immunology drug development to treat cancer and inflammatory diseases, today announced the initial Phase 1 results from the GLIMMER-01 trial of its lead EAGLE oncology platform program, E-602, at the American Association for Cancer Research (AACR) Annual Meeting 2023 in Orlando, Florida.
The study demonstrated proof of mechanism for E-602, a first-in-class glyco-immune checkpoint inhibitor, including dose dependent desialylation and dose dependent immune system activation. Additionally, E-602 was found to be well tolerated across the entire dose range evaluated with no dose limiting toxicities. Having met pre-specified gating criteria based on safety and pharmacodynamic activity, Palleon announced plans to proceed with Phase 2 evaluation.
“E-602 represents a truly novel immuno-oncology candidate that builds on the promise of glycobiology, a field of study that offers unprecedented opportunities for drug development in cancer and other diseases,” said David Feltquate, M.D., Ph.D., Chief Medical Officer of Palleon Pharmaceuticals. “Establishing proof of mechanism for this approach provides the validation necessary to initiate Phase 2 evaluation and take next steps towards our team’s shared goal of offering new options for patients in need.”
“It is exciting to see the first clinical results generated from Palleon’s EAGLE glyco-immunology drug development platform,” said Carolyn Bertozzi, Ph.D., Palleon Scientific Co-Founder and 2022 Nobel laureate. “Palleon is advancing an entirely new axis of immune modulation, defined by the interaction between sialoglycans and their receptors, which may benefit patients who do not respond to current medications.”
In the initial results from the GLIMMER-01 trial presented by lead investigator, Jason Luke, M.D., of UPMC Hillman Cancer Center, 40 patients were treated with at least one dose of E-602, the most common tumors treated being colorectal (n=21) and pancreatic (n=10). Doses up to 30 mg/kg were tolerated with no dose-limiting toxicities. Both dose-dependent desialylation and immune system activation, as measured by increases in activated (CD69+) immune cells in circulation and elevation of circulating cytokines and chemokines including IP-10/CXCL10, were observed. Phase 2 studies will evaluate clinical activity of E-602 monotherapy in patients with lung cancer and melanoma.

About Palleon Pharmaceuticals
Palleon Pharmaceuticals, co-founded by Nobel laureate Carolyn Bertozzi, is a biotechnology company pioneering glyco-immunology drug development to transform the treatment of cancer and inflammatory diseases. The Company’s proprietary platforms overcome technical barriers unique to glycobiology to enable drug discovery, patient selection, and indication prioritization to de-risk clinical development. The company’s lead program in oncology, E-602, is a first-in-class, glyco-immune checkpoint inhibitor which restores antitumor immunity by enzymatically degrading immunosuppressive sialoglycans on hypersialylated tumors and immune cells. It is being evaluated in a Phase 1/2 clinical trial. Palleon has a rich pipeline of additional drug candidates including several advancing toward IND-enabling studies.
