About

To assess the objective response rate of tumor lesions to abemaciclib in combination with pembrolizumab in patients with metastatic or recurrent squamous cell carcinoma of head and neck.

Full description

Immunotherapy has been recently approved for patients with metastatic or recurrent squamous cell carcinoma of the head and neck. However, only a small percentage of patients experience long-term control, necessitating new therapeutic strategies. Recently, it was shown preclinically and in breast tumors that abemaciclib stimulates production of type III interferons and hence enhances tumor antigen presentation. Abemaciclib also suppressed the proliferation of regulatory T cells. These events promote cytotoxic T-cell-mediated clearance of tumor cells, which is further enhanced by the addition of immune checkpoint blockade. Based on these data, a phase II trial in patients with metastatic or recurrent head and neck cancer who are eligible for immunotherapy is proposed to investigate the combination of abemaciclib with pembrolizumab. Tumor & blood analysis for interferon gamma signature will be explored as possible biomarkers.

Inclusion criteria

Histologically confirmed (core biopsy proven) metastatic or recurrent squamous cell carcinoma of head and neck
Adequate pulmonary and cardiac function
Available archived tissue of primary tumor or resected tumor specimen with adequate samples
Prior treatment with immune checkpoint inhibitor is not allowed in cohort 1 patients. Patients in cohort 2 should have failed or progressed on prior immune checkpoint inhibitor
Eastern Cooperative Oncology Group Performance Status(ECOG PS) = 0 or 1
Patients who received chemotherapy must have recovered (Common Terminology Criteria for Adverse [CTCAE] Grade <= 1) from the acute effects of chemotherapy except for residual alopecia or Grade 2 peripheral neuropathy prior to randomization. A washout period of at lease 21 days is required between last chemotherapy dose and randomization (provided the patient did not receive radiotherapy)
Patients who received adjuvant radiotherapy must have completed and fully recovered from the acute effects of radiotherapy. A washout period of at least 14 days is required between end of radiotherapy and randomization
The patient is able to swallow oral medications
Adequate hematologic and end-organ function
Absolute Neutrophil Count (ANC) >= 1500/mm3
Platelet count ≥ 100,000/mm3
Hemoglobin (Hb) ≥ 8g/dl (Patients may receive erythrocyte transfusions to achieve this hemoglobin level at the discretion of the investigator. Initial treatment must not begin earlier than the day after the erythrocyte transfusion)
Creatinine (Cr) ≤ 1.5 x Upper Limit of Normal (ULN) or Creatinine Clearance (CrCl) ≥ 60 ml/min
Total Bilirubin ≤ 1.5 x ULN (except subjects with Gilbert syndrome, who can have total Bilirubin < 2.0 x ULN and direct bilirubin within normal limits are permitted.)
Aspartate Aminotransferase (AST) and Alanine aminotransferase (ALT) and alkaline phosphatase ≤ ULN
Agreement to remain abstinent or use appropriate contraception, among women of childbearing potential
Willingness and ability to consent for self to participate in study
Willingness and ability to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures

Exclusion criteria

Autoimmune disease (Note: Vitiligo, type 1 diabetes mellitus, residual hypothyroidism due to autoimmune thyroiditis only requiring hormone replacement, and conditions not expected to recur in the absence of an external trigger are permitted.)
Condition requiring systemic treatment with either corticosteroids (>10 mg daily prednisone equivalent) or other immunosuppressive medications within 14 days prior to study treatment (Note: Inhaled and topical steroids, and adrenal replacement steroid doses > 10 mg daily prednisone equivalent, are permitted in the absence of active autoimmune disease.)
Preexisting medical condition(s) that would preclude participation in this study (for example, interstitial lung disease, severe dyspnea at rest or requiring oxygen therapy, history of major surgical resection involving the stomach or small bowel, or preexisting Crohn's disease or ulcerative colitis or a preexisting chronic condition resulting in baseline Grade 2 or higher diarrhea).
Immunosuppression, of any kind
Prior treatment with Cyclin-Dependent Kinase(CDK) 4/6 Inhibitor
Major surgical procedure or significant traumatic injury within 4 weeks prior to study treatment, and must have fully recovered from any such procedure
Personal history of any of the following conditions: syncope of cardiovascular etiology, ventricular arrhythmia of pathological origin (including, but not limited to, ventricular tachycardia and ventricular fibrillation), or sudden cardiac arrest
Angina, myocardial infarction (MI), symptomatic congestive heart failure, cerebrovascular accident, transient ischemic attack TIA), arterial embolism, pulmonary embolism, percutaneous transluminal coronary angioplasty (PTCA), or coronary artery bypass grafting (CABG) within 6 months prior to study treatment
Known active viral or non-viral hepatitis or cirrhosis
Any active infection requiring systemic treatment, positive tests for Hepatitis B surface antigen or Hepatitis C ribonucleic acid (RNA).
History of gastrointestinal perforation or fistula in the 6 months prior to study treatment, unless underlying risk has been resolved (e.g., through surgical resection or repair)
Known human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) related illness
Pregnancy or breastfeeding - Female patients must be surgically sterile (i.e., ≥6 weeks following surgical bilateral oophorectomy with or without hysterectomy or tubal ligation) or be postmenopausal, or must agree to use effective contraception during the study and for 4 months following last dose of treatment. All female patients of reproductive potential must have a negative pregnancy test (serum or urine) within 7 days prior to study treatment. Male patients must be surgically sterile or must agree to use effective contraception during the study and for 4 months following last dose of treatment.
Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or may interfere with the interpretation of study results and, in the judgment of the Investigator, would make the patient inappropriate for this study
