CAMBRIDGE, Mass., Sept. 30, 2019 (GLOBE NEWSWIRE) -- Cue Biopharma, Inc. (NASDAQ: CUE), a clinical-stage biopharmaceutical company engineering a novel class of injectable biologics to selectively engage and modulate targeted T cells within the body, announced today that on September 23, 2019 it dosed the first patient in a Phase 1 clinical trial of CUE-101 at Washington University, Alvin J. Siteman Cancer Center, St. Louis, Missouri for the treatment of HPV16-driven recurrent/metastatic head and neck squamous cell carcinoma (HNSCC). Enabled by the company’s proprietary Immuno-STAT™ (Selective Targeting and Alternation of T cells) platform, CUE-101 is the company’s lead biologic drug candidate from the IL-2 based CUE-100 series, designed to directly engage and activate T cells in the body to target HPV-driven cancers.
“We are very pleased to have begun dosing patients with CUE-101, the first drug candidate from our CUE-100 series designed by our proprietary Immuno-STAT platform. We believe CUE-101 has the potential to activate the patient’s immune system against HPV16-driven cancers by selectively targeting and activating the patient’s T cells directly within their body, representing a potential breakthrough approach for harnessing the therapeutic power of the body’s immune system,” said Dan Passeri, president and chief executive officer of Cue Biopharma.
Ken Pienta, M.D., acting chief medical officer of Cue Biopharma, added, “As an oncologist, I am extremely excited about this promising new approach to treat cancer by stimulating a patient’s own immune system. We are thrilled to enroll patients suffering from refractory HPV16 positive head and neck cancer.”
“Initiating this Phase 1 clinical study of CUE-101 is a significant milestone for Cue Biopharma,” said Anish Suri, Ph.D., chief scientific officer of Cue Biopharma. “The Phase 1 clinical trial is designed with a translational approach to determine CUE-101’s ability to selectively activate and expand patients’ own endogenous HPV16-specific T cell repertoire to target tumor cells. Historically, the majority of focus for cancer immunotherapy has been on broad, non-specific immune modulation or highly complex ex vivo cell therapies that are time consuming and cumbersome to produce. CUE-101 is a highly stable protein engineered to mimic the activity of antigen-presenting cells to interact directly with the existing T cells in the body that are specific for the HPV epitope driving the HNSCC. Upon binding, CUE-101 provides the necessary signals, in this case IL-2 that cause naturally occurring T cells in the patient’s body to proliferate and target the tumor. This trial is unique in that the T cells act as the target of the drug treatment as well as the therapeutic itself. Importantly, our pipeline candidates, derived from the Immuno-STAT platform, can be injected directly into the patient’s body and do not involve ex vivo manipulation of T cells. We believe that through our approach, the true potential of a patient’s own immune system may be realized in the fight against cancer.”
The trial (NCT03978689) is a multi-center, open-label, Phase 1 dose escalation and expansion study evaluating the safety, anti-tumor effect, and immunogenicity of CUE-101 as a monotherapy in patients with confirmed HPV16-driven recurrent/metastatic HNSCC and HLA-A*02:01 serotype. The study is designed to enroll approximately 50 patients. Based on translational analysis/data from the trial, the company may expand the study to test CUE-101 both as a neoadjuvant therapy and potentially in combination with checkpoint inhibitors in patients with HPV16-driven recurrent/metastatic HNSCC.
HPV-driven cancers account for more than 20,000 deaths each year in the U.S. and Europe. The majority of these cancers are driven by HPV16 which carries the E7 antigen targeted by CUE-101. Despite treatment with current standards of care, approximately 50% of patients with advanced disease will experience recurrence and significant quality of life impact. Patients with HPV-driven cancers represent an important unmet clinical need and underscore the opportunity for promising new therapeutics.
About CUE-100 Series
Product candidates developed within the CUE-100 series are designed to selectively target tumor-specific T cells peptide-MHC complexes (pMHC) in combination with interleukin 2 (IL-2), which together are critical to the activation, expansion and survival of T cells. The binding affinity of IL-2 for its receptor has been attenuated to achieve preferential selective activation of tumor-specific T cells without broad systemic activation, potentially mitigating the dose-limiting toxicities associated with current IL-2-based therapies.
The lead program from the CUE-100 series, CUE-101, contains IL-2 and a pMHC composed of HLA-A*02:01 complexed with a dominant peptide derived from the human papilloma virus 16 E7 protein (HPV16-E7). The drug is a fusion protein biologic designed to target and activate antigen-specific T cells to attack HPV-driven cancers.
Immuno-STAT biologics are designed for targeted modulation of disease-associated T cells in the areas of immuno-oncology and autoimmune disease. Each of our biologic drugs is designed using our proprietary scaffold comprising: 1) a peptide-MHC complex (pMHC) to provide selectivity through the pMHC T cell receptor (TCR) interaction, and 2) a unique co-stimulatory signaling molecule to modulate the activity of the target T cells.
The simultaneous engagement of co-stimulatory molecules and pMHC binding mimics the signals delivered by antigen presenting cells (APCs) to T cells during a natural immune response. This design enables Immuno-STAT biologics to engage with the T cell population of interest, resulting in highly targeted T cell modulation. Because our drugs are delivered in vivo, they are fundamentally different from other T cell therapeutic approaches, which require the patients’ T cells to be extracted, then stimulated and expanded outside the body (ex vivo) and reinfused in an activated state.
