Brief Summary:
In this study, patients with recurrent or metastatic head and neck squamous cell carcinoma will receive first line treatment with olaparib, pembrolizumab, and carboplatin. The primary hypothesis is that olaparib, pembrolizumab and carboplatin will result in an overall response rate (ORR) higher than the historical ORR observed with pembrolizumab, platinum and 5-FU.

Arm Intervention/treatment
Experimental: Olaparib + Pembrolizumab + Carboplatin AUC

-Patients enrolled in this study will receive olaparib, pembrolizumab and carboplatin in three-week cycles for six cycles, followed by maintenance therapy with three-week cycles of olaparib and pembrolizumab. Treatment will continue until disease progression, intolerable toxicity, patient or physician decision to stop therapy, or after 35 cycles, whichever occurs first. Drug dosing for each cycle is as follows:

  • Olaparib 200 mg twice per day (bid) by mouth (po) Days 1-10 for the first six cycles (when given with carboplatin), followed by 400 mg bid po Days 1-21 of subsequent cycles.
  • Pembrolizumab 200 mg intravenous (IV) Day 1.
  • Carboplatin AUC 5 IV on Day 1 for up to six cycles.

Criteria

Inclusion Criteria:

  • Diagnosis of histologically or cytologically confirmed recurrent or metastatic HNSCC of the oral cavity, oropharynx, larynx, hypopharynx, or p16+ SCC of the neck (unknown primary).
  • Measurable disease per RECIST. Measurable disease defined as lesions that can be accurately measured in at least one dimension (longest diameter to be recorded) as ≥ 10 mm with CT scan, as ≥ 20 mm by chest x-ray, or ≥ 10 mm with calipers by clinical exam.
  • Incurable disease, or ineligible for (including patient declined) local therapy.
  • At least 18 years of age.
  • ECOG performance status ≤ 1
  • Life expectancy ≥ 16 weeks.
  • Normal bone marrow and organ function as defined below:

    • Hemoglobin ≥ 10.0 g/dL
    • Absolute neutrophil count ≥ 1,500/mcL
    • Platelets ≥ 100,000/mcL
    • INR or PT ≤ 1.5 x institutional upper limit of normal (IULN) and aPTT ≤ 1.5 x IULN unless participant is receiving anticoagulant therapy as long as PT or aPTT is within therapeutic range of intended use of anticoagulants
    • Total bilirubin ≤ 1.5 x IULN
    • AST(SGOT)/ALT(SGPT) ≤ 2.5 x IULN unless liver metastases are present (in which case they must be ≤ 5 x IULN)
    • Serum creatinine <1.5 x ULN or creatinine clearance ≥ 51 mL/min by Cockcroft-Gault or based on a 24-hour urine test
  • Known p16 expression, if oropharyngeal primary.
  • Postmenopausal or evidence of non-childbearing status for women of childbearing potential: negative urine or serum pregnancy test within 28 days of study treatment and confirmed prior to treatment on Day 1.

    *Postmenopausal is defined as:

    • Amenorrheic for 1 year or more following cessation of exogenous hormonal treatments
    • Luteinizing hormone (LH) and Follicle stimulating hormone (FSH) levels in the post menopausal range for women under 50
    • radiation-induced oophorectomy with last menses >1 year ago
    • chemotherapy-induced menopause with >1 year interval since last menses
    • surgical sterilization (bilateral oophorectomy or hysterectomy)
  • Male patients must use a condom during treatment and for 3 months after the last dose of olaparib when having sexual intercourse with a pregnant woman or with a woman of childbearing potential. Female partners of male patients should also use a highly effective form of contraception (see Section 5.6) if they are of childbearing potential
  • Ability to understand and willingness to sign an IRB approved written informed consent document (or that of legally authorized representative, if applicable).

Exclusion Criteria:

  • Progression within 6 months of curatively intended systemic therapy given for locoregionally advanced disease.
  • Investigational therapy within 28 days of treatment start.
  • Prior systemic therapy for recurrent or metastatic disease.
  • No known CNS metastases/leptomeningeal metastatic disease.
  • Other malignancy unless curatively treated with no evidence of disease for ≥ 2 years except: adequately treated non-melanoma skin cancer, curative treated in situ cancer of the cervix, ductal carcinoma in situ (DCIS), stage 1 grade 1 endometrial carcinoma; or low risk-disease per discretion of the PI.

Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette-Guerin (BCG), and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (e.g. FluMist®) are live attenuated vaccines and are not allowed.
  • Considered a poor medical risk due to a serious, uncontrolled medical disorder, non-malignant systemic disease, or active, uncontrolled infection. Examples include, but are not limited to, uncontrolled ventricular arrhythmia, recent (within 3 months) myocardial infarction, uncontrolled major seizure disorder, unstable spinal cord compression, superior vena cava syndrome, extensive interstitial bilateral lung disease on high resolution computed tomography (HRCT) scan or any psychiatric disorder that prohibits obtaining informed consent.
  • Unable to swallow orally administered medication or with gastrointestinal disorder likely to interfere with absorption of study medication.
  • Pregnant and/or breastfeeding. Women of childbearing potential must have a negative serum pregnancy test within 72 hours of first dose of treatment.
  • Prior organ or allogeneic stem cell transplant or double umbilical cord blood transplantation.
  • Has an active autoimmune disease (i.e. rheumatoid arthritis, lupus, Sjogren's syndrome) that has required IV or subcutaneous systemic treatment in the past 6 months (excluding Rituxan). Replacement therapy (i.e. thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment. Patients who are known to be serologically positive for HIV or have known active hepatitis B or C are ineligible.
  • History of (non-infectious) pneumonitis that required steroids or has current pneumonitis.
  • Has a known history of active TB (Bacillus Tuberculosis).
