Cue Biopharma, Inc. a clinical-stage biopharmaceutical company developing a novel class of injectable biologics to selectively engage and modulate targeted T cells directly within the patient’s body, announced that the U.S. Food and Drug Administration (FDA) has accepted the Company's Investigational New Drug (IND) application for the evaluation of CUE-102, its second interleukin 2 (IL-2)-based CUE-100 series biologic, in a dose escalation and expansion monotherapy Phase 1 trial, which will have a starting dose of 1 mg/kg for the treatment of Wilms’ Tumor 1 (WT1)-positive recurrent/metastatic cancers, with initial focus on gastric, pancreatic, ovarian and colon cancers.
CUE-102 supports the modularity of the IL-2 based CUE-100 series as the core biologic framework is largely conserved with the primary difference being the incorporation of the WT1 T cell epitope. The IND acceptance allowing the dose escalation trial to begin dosing at 1 mg/kg was supported by the safety and tolerability data from the CUE-101 trial. CUE-101, the first biologic from the CUE-100 series, had a starting dose of 0.06 mg/kg and required approximately 9 months to dose escalate from 0.06 mg/kg to 1 mg/kg. As such, the starting dose of CUE-102 (targeting WT1 expressing cancers) may provide substantive time and cost savings for potentially demonstrating tolerability at therapeutically effective doses.
"The ability to start our dose escalation trial at 1 mg/kg, is significant as it allows us to initiate the trial at a dose level that demonstrated signs of clinical activity in our CUE-101 trial. At this dose level, we can potentially determine tolerability and therapeutically effective doses much more efficiently by truncating the dose escalation process,” stated Ken Pienta, M.D., acting chief medical officer of Cue Biopharma. “We believe CUE-102 provides a significant opportunity to address a high unmet medical need in a wide variety of WT1-positive malignancies including colorectal, pancreatic and lung, and potentially offers a tolerable and more effective treatment option to patients in need. We believe CUE-102 has the potential to change the treatment landscape for WT1-positive patients and are very pleased to now begin evaluating its potential benefit in the clinic.”
Anish Suri, Ph.D., president and chief scientific officer of Cue Biopharma said, “The IND acceptance of CUE-102 is a step forward in support of our strategic vision for pipeline expansion of assets emerging from our IL-2-based CUE-100 series of Immuno-STATs. Since the core framework and the IL-2 components are conserved, the clinical de-risking achieved with CUE-101 should in principle allow us to develop subsequent therapeutic molecules in a significantly expedited and cost-effective manner. To that end, we believe that FDA clearance to initiate the CUE-102 clinical trial at 1 mg/kg dose is an important step forward to the platform de-risking achieved with our current clinical candidate, CUE-101.”
FDA acceptance of the IND application for CUE-102 is another important milestone for Cue Biopharma in their multi-target strategic collaboration with LG Chem Life Sciences, the life sciences division of LG Chem Ltd., to develop multiple Immuno-STAT biologics focused in the field of oncology.
