About the study

This 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 monotherapy treatment in second line or CUE-101 Combination Therapy with Pembrolizumab in first line patients with HPV16+ Recurrent/Metastatic Head and Neck Squamous Cell Carcinoma (HNSCC)

Who can take part?

You may be eligible to participate in the study if you meet the following criteria:

Inclusion criteria

General:

1. Ability to provide informed consent and documentation of informed consent prior to initiation of any study-related tests or procedures that are not part of standard of care for the patient's disease. Patients must also be willing and able to comply with study procedures, including the acquisition of specified research specimens.
2. Age ≥18 years old
3. ECOG performance status of 0 or 1
4. Life expectancy ≥12 weeks
5. Measurable disease as per RECIST 1.1 and documented by CT and/or MRI by the local site investigator/radiology. At least 1 lesion that can be accurately measured in at least 2 dimensions with spiral CT scan. Minimum measurement must be >15 mm in the longest diameter by >10 mm in the short axis. Cutaneous or subcutaneous lesions must be measurable by calipers. Note: Lesions to be used as measurable disease for the purpose of response assessment must either a) not reside in a field that has been subjected to prior radiotherapy, or b) have demonstrated clear evidence of radiographic progression since the completion of prior radiotherapy and prior to study enrollment.
6. All tumors must have histologically or cytologically confirmed diagnoses of recurrent and/or metastatic HNSCC.
7. Patient must have HLA A*0201 genotype as determined by genomic testing performed at a central laboratory designated by the Sponsor prior to enrollment.
8. Patient must have tumor(s) that are HPV16+ and express 16INK4A. Archival tissue or FFPE tissue from a biopsy and/or surgery must be available for HPV16 and p16INK4A testing on all patients enrolled. All tumors must test positive for both HPV16 using RNA ISH and p16INK4A expression in tumor cells using IHC analysis determined in a central laboratory designated by the Sponsor.
9. Patient must have tumor expression of PD L1 (CPS ≥1) as determined by an FDA-approved test. Laboratory Features
10. Acceptable laboratory parameters as follows:
11. Platelet count ≥100 × 103/μL
12. Hemoglobin ≥9.0 g/dL. Criteria must be met without erythropoietin dependency and without pRBC transfusion within last 2 weeks.
13. Absolute neutrophil count ≥1.5 × 103/μL in the absence of any growth factor support within 2 weeks prior to the initiation of study drug
14. ALT or AST ≤2.5 × ULN; for patients with hepatic metastases, ALT and AST ≤5 × ULN
15. Total bilirubin ≤1.5 × ULN, except patients with Gilbert's syndrome, who may enroll if the conjugated bilirubin (total and direct) is within normal limits
16. Creatinine ≤1.5 mg/dL, or a calculated or measured creatinine clearance ≥30 mL/min. Creatinine clearance should be calculated as per institutional standard. >1.5 x institutional ULN. Glomerular filtration rate (GFR) can also be used in place of creatinine or creatinine clearance.
17. Coagulation: INR or PT ≤1.5 × ULN unless participant is receiving anticoagulant therapy as long as PT or aPTT is within the therapeutic range of anticoagulants. Reproductive Features
18. A male participant must agree to use contraception during the treatment period and for at least 120 days following discontinuation of study treatment.
19. A female participant is eligible to participate if she is not pregnant, not breastfeeding, and at least 1 of the following conditions applies:
20. Not a woman of childbearing potential (WOCBP)
21. A WOCBP who agrees to follow contraceptive guidance during the treatment period and for at least 120 days after the last dose of study treatment.

Exclusion criteria

1. Patients who have received prior therapy for R/M disease.
2. Patients with symptomatic CNS metastases must have been treated, be asymptomatic, and not have any of the following at the time of enrollment:
3. Need for concurrent treatment for the CNS disease (eg, surgery, radiation, corticosteroids >10 mg prednisone/day or equivalent);
4. Progression of CNS metastases on MRI or CT for at least 28 days after last day of prior therapy for the CNS metastases. If brain imaging is performed to document the stability of existing metastases, MRI should be used if possible. If MRI is medically contraindicated, CT with contrast is an acceptable alternative.
5. and/or concurrent leptomeningeal disease or cord compression.
6. Has an active autoimmune disease that has required systemic treatment in past 2 years (ie, with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (eg, thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment and is allowed.
7. History of prior allogeneic bone marrow, stem-cell or solid organ transplantation
8. Treatment with prior systemic anti-cancer therapy including investigational agents within 4 weeks for antibodies or 5 half-lives for other therapies, whichever is shorter, prior to administration of the study drug. Patients may be on an investigational or other anti-neoplastic therapy during the screening phase of the study.
9. Treatment with radiation therapy within 2 weeks prior to the initiation of study drug administration.
10. Treatment with corticosteroids (>10 mg per day prednisone or equivalent) or other immune suppressive drugs within the 14 days prior to the initiation of study drug administration.
11. History of clinically significant cardiovascular disease including, but not limited to:
12. Myocardial infarction or unstable angina within the 16 weeks prior to the initiation of study drug
13. Clinically significant cardiac arrhythmias
14. Uncontrolled HTN: systolic BP >180 mm Hg, diastolic BP >100 mm Hg

19. Myocarditis
20. Clinically significant pulmonary compromise (eg, requirement for supplemental oxygen)

24. History of acute pancreatitis within 3 months prior to the initiation of study drug; and/or
25. Diverticulitis that is clinically significant in the opinion of the investigator based on the extent or severity of known disease and/or the occurrence of clinically significant disease flares within 4 weeks prior to the initiation of study drug administration.
26. Severe hypersensitivity to pembrolizumab excipients.
27. Evidence of active viral, bacterial, or systemic fungal infection requiring parenteral treatment within 7 days prior to the initiation of study drug. Patients requiring any systemic antiviral, antifungal, or antibacterial therapy for active infection must have completed treatment no less than 1 week prior to the initiation of study drug.
