Trial of Nivolumab as a Novel Neoadjuvant Pre-Surgical Therapy for Locally Advanced Oral Cavity Cancer
Study Details
Study Description
Brief Summary
The purpose of this study is to look at the effectiveness of nivolumab in patients with oral cavity cancer (OCC) who are about to undergo surgery.
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|
| Phase 2 |
Detailed Description
OCC patients who are scheduled for surgery will be given Nivolumab prior to surgery to see if there are any changes in surgical outcomes.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Nivolumab Nivolumab (OPDIVO) will be administered every two weeks for up to four doses prior to surgery at 3mg/kg |
Drug: Nivolumab
Nivolumab will be administered on days 1, 15 and 29. If disease has progressed at day 29, the subject will proceed to surgery. If a response or stable disease is present after the third dose, a fourth dose will be given on day 43, then the subject will proceed to surgery.

Outcome Measures
Primary Outcome Measures
- Objective response rate using pathological response [Time of surgery (day 36 or day 50)]
Objective response rate: the sum of patients with either a pCR defined as no invasive and no in situ residuals present in the surgical specimen or partial pathologic response defined at least a 30% reduction in the size of the lesion in the surgical specimen. The reduction in size will be determined by comparing the pretreatment clinical measurements (the sum of the greatest axial measurement obtained with calipers at the time of initial evaluation) with the final pathologic measurements.
Secondary Outcome Measures
- Level of Treg cells in peripheral blood using immunostaining [Day 1 and time of surgery (day 36 or day 50)]
1. Levels of Treg cells in pre and post treatment peripheral blood will be evaluated using immunostaining for CD4 and flow cytometric analysis of Foxp3. Differences will be calculated (absolute change and percentage change) between pre and post treatment measures.
- Level of activated T-cells in peripheral blood [Day 1 and time of surgery (day 36 or day 50)]
2. Levels of activated T-cells in peripheral blood will be assessed using flow cytometry for expression of CD69, IFN γ, T-bet and ICOS in CD4+ cells. Differences will be calculated (absolute change and percentage change) between pre and post treatment measures.
- Level of immune stimulatory cytokines in peripheral blood [Day 1 and time of surgery (day 36 or day 50)]
3. Intratumoral immune activity assessed by levels of immune stimulatory cytokines including IL-2, IFN γ, and IL-12 or inhibitory cytokine, IL10 and TGF-beta, in OCSCC tumor lysates will be measured flow cytometrically by cytokine bead array. Differences will be calculated (absolute change and percentage change) between pre and post treatment measures.
- Expression of Th1 responses in CD4+ cells from peripheral blood [Day 1 and time of surgery (day 36 or day 50)]
Expression of IL-2 (Th1 responses) in CD4+ cells from peripheral blood of patients following PD-1 inhibition therapy will be compared between pre-treatment peripheral blood samples and post-treatment samples from the same patient.
- Expression of Th2 responses in CD4+ cells from peripheral blood [Day 1 and time of surgery (day 36 or day 50)]
Expression of IIL 10 (Th2 responses) in CD4+ cells from peripheral blood of patients following PD-1 inhibition therapy will be compared between pre-treatment peripheral blood samples and post-treatment samples from the same patient.
- Expression of CD8+ cells expressing granzyme B (ctolytic response) from peripheral blood [Day 1 and time of surgery (day 36 or day 50)]
2. Expression of CD8+ cells expressing granzyme B (cytolytic response) from peripheral blood of patients following PD-1 inhibition therapy will be compared between pre-treatment peripheral blood samples and post-treatment samples from the same patient.
Eligibility Criteria
Criteria
Inclusion Criteria:
- Newly diagnosed histologically proven locoregional OCSCC without evidence of distant metastases and a clinically determined T-stage of 2-4,
OR
Recurrent or persistent histologically proven locoregional OCSCC that was initially treated with surgery alone, and a clinically determined recurrent T-stage of 2-4.
Note - OCSCC includes the subsites of oral tongue, floor of mouth, gingiva, retromolar trigone, and buccal mucosa.
Note - To allow sufficient tumor tissue for the immunological analyses, patients with T-stage 1 OCSCC will be excluded
-
Greater than or equal to 18 years of age
-
ECOG performance status of 0 or 1
-
Screening labs must meet the following criteria and must be obtained within 14 days prior to registration:
-
WBC > 2,000/µL
-
Absolute Neutrophil Count >1,500/µL
-
Platelets > 100 X 103/µL
-
Hemoglobin > 9.0 g/dL
-
Serum creatinine < 1.5 X ULN or CrCl > 40mL/min (if using the Cockcroft-Gault formula below):
Female CrCl = (140 - age in years) x weight in kg x 0.85 72 x serum creatinine in mg/dL Male CrCl = (140 - age in years) x weight in kg x 1.00 72 x serum creatinine in mg/dL
-
AST/ALT ≤ 3 x ULN
-
Total Bilirubin ≤ 1.5 x ULN (except subjects with Gilbert Syndrome, who can have total bilirubin < 3.0 mg/dL)
- Reproductive Status:
WOCBP must use appropriate method(s) of contraception. WOCBP should use an adequate method to avoid pregnancy for 23 weeks (30 days plus the time required for nivolumab to undergo five half-lives) after the last dose of investigational drug.
Men receiving nivolumab and who are sexually active with WOCBP will be instructed to adhere to contraception with a failure rate of less than 1% per year for a period of 31 weeks after the last dose of investigational product.
WOCBP is defined as any female who has experienced menarche and who has not undergone surgical sterilization (hysterectomy or bilateral oophorectomy) or who is not postmenopausal. Menopause is defined clinically as 12 consecutive months of amenorrhea in a woman over 45.
Women of childbearing potential must have a negative serum pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 24 hours prior to registration Women who are not of childbearing potential (i.e., who are postmenopausal or surgically sterile) and azoospermic men, are not required to use contraception.
Exclusion Criteria:

Inhaled or topical steroids and adrenal replacement doses > 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease
