BOSTON, Nov. 10, 2022 (GLOBE NEWSWIRE) -- Cue Biopharma, Inc. (Nasdaq: CUE), a clinical-stage biopharmaceutical company developing a novel class of injectable biologics to selectively engage and modulate tumor-specific T cells directly within the patient’s body, announced today the presentation of new positive data from its ongoing Phase 1 trial evaluating its lead interleukin 2 (IL-2)-based biologic, CUE-101 in combination with pembrolizumab (KEYTRUDA), as a first line therapy for patients with recurrent/metastatic HPV+ head and neck squamous cell carcinoma (HNSCC). The data will be presented in a poster at the Society for Immunotherapy of Cancer’s 37th Annual Meeting ( SITC 2022 ), to be held in Boston, Massachusetts and virtually on November 8-12, 2022.
The poster will also provide an update from the Company’s ongoing fully enrolled Phase 1b trial evaluating CUE-101 monotherapy as third line and beyond therapy in the same patient population. Additionally, the Company will present two posters discussing the design of its ongoing Phase 1 trial evaluating its second IL-2 based candidate, CUE-102, for the treatment of Wilms’ Tumor 1 positive (WT1+) malignancies, and preclinical data regarding its mechanistic effect in vitro and in vivo.
“We are very encouraged with the overall response rate observed in the trial so far with CUE-101, and its potential to improve standard of care for HPV+ head and neck cancer patients,” said Dr. Christine Chung, M.D., Chair, Department of Head and Neck-Endocrine Oncology, Moffitt Cancer Center, and a principal investigator participating in the clinical trial. “There is an urgent need for more effective and durable treatment options with less side effects as more than half of all patients with recurrent/metastatic HNSCC given the current standard of care will experience disease progression. I look forward to following this promising CUE-101 clinical data through.”
Key data highlights from the CUE-101 dose escalation and patient expansion portion of the Phase 1 trial in combination with pembrolizumab with 16 evaluable patients to date, include:
Key data highlights from the CUE-101 expansion portion of the Phase 1b trial at the RP2D as a monotherapy to date, include:
CUE-101 continued to show a favorable tolerability profile both as monotherapy and in combination with pembrolizumab.
Ken Pienta, M.D., acting chief medical officer of Cue Biopharma, added, “This new data from our combination study demonstrates early evidence of complementary mechanistic activity of CUE-101 with pembrolizumab. In addition, the sustained clinical benefit rate with CUE-101 as monotherapy is very encouraging and has continued to demonstrate proof-of-concept of CUE-101 as a single agent. Overall, the data shows the potential of CUE-101 to provide patients with an improved clinical benefit rate and with lower toxicity than current standard of care. We look forward to continuing to evaluate data from the trial in addition to defining the potential registrational trial for CUE-101, which we anticipate in mid-2023.”
Anish Suri, Ph.D., president and chief scientific officer of Cue Biopharma, said, “Initiation of the Phase 1 trial evaluating our second IL-2-based biologic, CUE-102, is also an important milestone for the company as we continue to demonstrate the versatility and modularity of our platform to potentially treat multiple cancers. CUE-102 shares the core molecular structure of CUE-101, with primary differences in the tumor-specific T cell epitope. This similarity together with our preclinical data that demonstrated CUE-102’s ability to elicit selective expansion of WT1-specific T cells, support our belief for a potential positive tolerability profile and clinical activity. We look forward to sharing updated data on this trial in the coming year.”
Key data highlights from CUE-102 preclinical study to date include:
All three posters will be available in the Investor & Media section of the Company’s website at www.cuebiopharma.com under Scientific Publications and Presentations.

About HPV+ Recurrent or Metastatic Head and Neck Cancer
Head and neck squamous cell carcinomas (HNSCC) are the 8th most common cancer in the world. A significant subset of the cases of HNSCC includes human papillomavirus (HPV) associated oropharyngeal tumors, with HPV16 detectable in 80%-90% of these cases. Despite the current standard of care treatments, more than 50% of patients with advanced HNSCC will experience recurrence, representing a significant unmet need.
About the CUE-100 Series
The CUE-100 series consists of Fc-fusion biologics that incorporate peptide-MHC (pMHC) molecules along with rationally engineered IL-2 molecules. This singular biologic is anticipated to selectively target, activate and expand a robust repertoire of tumor-specific T cells directly in the patient’s body. The binding affinity of IL-2 for its receptor has been deliberately attenuated to achieve preferential selective activation of tumor-specific effector T cells while reducing the potential for effects on regulatory T cells (Tregs) or broad systemic activation, potentially mitigating the dose-limiting toxicities associated with current IL-2-based therapies.
