Brief Summary:
This is a Phase 1 Window of Opportunity study to evaluate the pharmacodynamic and immune effects of pre-operative therapy with Mocetinostat and Durvalumab on patients with squamous cell carcinoma of the oral cavity.

Condition or disease Intervention/treatment Phase
Squamous Cell Carcinoma, Head And Neck Squamous Cell Carcinoma Mouth Resectable Squamous Cell Carcinoma of Oral Cavity Drug: Mocetinostat Biological: Durvalumab Phase 1

Detailed Description:

This is a single center, open-label, non-randomized, pre-operative window of opportunity study for patients with resectable squamous cell carcinoma of the oral cavity who are considered suitable for curative-intent surgical resection, with pre-operative Mocetinostat and Durvalumab.

This study will involve treatment with Mocetinostat and Durvalumab, tests and procedures done for safety and the collection of blood samples for biomarker research. Tissue samples (fresh biopsy or archival tissue) will also be collected for biomarker research and evaluation.

Drug Information available for: Durvalumab

Arm Intervention/treatment
Experimental: Mocetinostat and Durvalumab

Patients will start therapy with mocetinostat within 10 days of study enrollment. Mocetinostat will be given in 2 dose levels (n = 6 evaluable patients each) of 70mg three-times weekly and 90mg three-times weekly for 2 weeks.

Durvalumab will be given as a single infusion at a dose of 1500mg, over a period of 1-hour, on day 8 of the study.

Drug: Mocetinostat
Mocetinostat (MGCD0103) is a potent small molecule HDAC inhibitor that targets human HDAC isoforms. It is an orally bioavailable, second generation benzamide inhibitor of HDAC 1, 2, 3 and 11 with broad spectrum antitumor activity in vitro and in vivo.
Other Name: MGCD0103

Biological: Durvalumab
Durvalumab is a human immunoglobulin G1 kappa (IgG1κ) monoclonal antibody directed against human PD-L1. It is selective for recombinant PD-L1 and blocks the binding of recombinant PD-L1 to the PD-1 and CD80 receptors.
Other Name: MEDI4736

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Signed written and voluntary informed consent.
  2. Patient must be willing and able to comply with scheduled visits, treatment plan, laboratory tests and other study procedures.
  3. Age > 18 years, male or female. Disease characteristics
  4. Patient must be diagnosed with histologically confirmed squamous cell carcinoma of the oral cavity (SCCOC) (floor of mouth, anterior 2/3 tongue, buccal mucosa, upper and lower gingiva, and retromolar trigone) considered resectable by the head and neck surgical rounds (T2-4a, N0-2, M0; without evidence of distant metastasis).
  5. Patient must be willing and able to provide up to 2 fresh tumor biopsies for histopathological and biomarker evaluation; first as pre-treatment baseline, and the second after treatment with mocetinostat but prior to treatment with durvalumab.

    • Patients who decline an in-house fresh pre-treatment tumor biopsy must give consent to provide a tumor block from an existing diagnostic primary tumor biopsy completed within 90 days of enrollment, which is of acceptable quality and quantity for analysis, as assessed by the study site correlatives team.
  6. No anti-neoplastic treatment is allowed between the time from obtaining baseline tumor specimen and enrollment.

    Patient characteristics

  7. ECOG performance status 0-1.
  8. Patient must have adequate organ function as determined by the following:

    - Renal function: i. Serum creatinine < 1.5 ULN (upper limit of normal range) or a calculated creatinine clearance of > 50mL/min using the following formula: Creatinine clearance = [(140-age) x wt (kg) x Constant*] / creatinine (umol/L)

    *Constant = 1.23 for men, and 1.04 for women

    - Bone marrow function (without hematopoietic growth factors or transfusion): i. Absolute neutrophil count (ANC) > 1.5 x 109/L ii. Leukocytes > 3.0 x 109/L iii. Hemoglobin > 90 g/L or > 9g/dL iv. Platelets > 100 x 109/L
