About
This randomized phase IIb trial studies how well ACTOplus met extended release (XR) works in treating in patients with stage I-IV oral cavity or oropharynx cancer that are undergoing definitive treatment. Chemoprevention is the use of drugs to keep oral cavity or oropharynx cancer from forming or coming back. The use of ACTOplus met XR may slow disease progression in patients with oral cavity or oropharynx cancer.
Full description
PRIMARY OBJECTIVES:
I. To determine whether 10-21 days of treatment with ACTOplus met XR will result in a decrease in proliferation index (Ki-67) expression in oral cavity/oropharyngeal tumor tissue as compared to placebo.
SECONDARY OBJECTIVES:
I. Compare differences in proliferation index (Ki-67) expression from baseline to post-exposure in visually normal appearing oral cavity/oropharyngeal tissue.
II. Compare immunohistochemical differences in the apoptosis biomarker cleaved caspase 3 from baseline to post-exposure in oral cavity/oropharyngeal adjacent visually normal appearing tissue and tumor tissue samples.
III. Compare immunohistochemical differences from baseline to post-exposure in oral cavity/oropharyngeal tumor tissue samples with regard to cyclin D1, p21 and biguanide or PPAR gamma associated pathway biomarkers; prospective biomarkers on the panel will include phosphorylated (p)AKT, pAMPK, pS6 (metformin), and PPAR gamma.
IV. Compare immunohistochemical differences from baseline to post-exposure of oral cavity/oropharyngeal tumor tissue samples with regard to tumor infiltrating immune cells (effector CD8 [CD8+]), regulatory CD4 T regulatory (Treg) (CD4+Foxp3+), tumor associated myeloid cells (CD68), PD1 and PD-L1.
V. Compare and correlate pre- and post-ACTOplus met XR treatment human ribonucleic acid (RNA)-sequencing (seq) gene analysis on total RNA samples from oral cavity/oropharyngeal adjacent visually normal appearing tissue and tumor tissue pre-and post-study treatment.
VI. Determine human papillomavirus (HPV) status in pre-treatment tumor tissue using p16 immunohistochemistry.
EXPLORATORY OBJECTIVES I. Compare pre- and post-study treatment fludeoxyglucose F-18 (FDG)-positron emission tomography (PET)/computed tomography (CT) scans with regard to standardized uptake value (SUV) of FDG and tumor burden using Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1 in those participants with a preintervention standard of care staging FDG-PET/CT.
OUTLINE: Patients are randomized to 1 of 2 groups.
GROUP I: Patients receive ACTOplus met XR orally (PO) once daily (QD) for 10-21 days in the absence of disease progression or unacceptable toxicity. Patients may continue ACTOplus met XR PO QD for a maximum of 25 days if end of treatment biopsy/surgical treatment is delayed beyond day 22.
GROUP II: Patients receive placebo PO QD daily for 10-21 days.

Inclusion criteria
-
Participant has a newly diagnosed, histologically confirmed, stage I-IV squamous cell carcinoma or squamous cell carcinoma in situ of the oral cavity or oropharynx and will be undergoing definitive surgical, radiotherapy, or chemoradiation treatment; patients who are NOT candidates for localized treatment (surgery, radiation or chemoradiation) with curative intent (i.e.patients with distant metastasis or contra-indication to localized treatment) are not eligible OR
-
Participant has a lesion in the oral cavity or oropharynx that is not yet biopsied but is highly suspicious for cancer; (randomization will be placed on hold until the presence of cancer is histologically confirmed, and a treatment plan is established; if the presence of cancer is not confirmed, the participant will be considered a screen failure)
-
The participant's primary tumor is accessible for the collection of 4 mm samples of tumor and adjacent visually normal appearing tissue for biomarker analysis and the participant is willing to have these samples collected at baseline and at the end of study visit. (The protocol requires the collection of fresh tissue for biomarker analysis)
-
Patients who have not yet had a diagnostic biopsy:
-
The tissue samples for biomarker analysis may be collected in conjunction with the patient's standard of care diagnostic biopsy but not until after the patient has signed informed consent and it has been determined that they meet all of the eligibility criteria for this protocol with the exception of normal organ and marrow function as defined by the clinical laboratory test results listed for that criterion. In this situation, because the patient would be having a biopsy regardless of whether or not they were participating in this study, it is not required to obtain these results prior to conducting the biopsy. It is however, required to confirm normal organ and marrow function prior to randomization.
-
Patients who are scheduled for a direct operative laryngoscopy with biopsy (DL biopsy) for diagnostic purposes may be candidates for this study provided the following criteria are met:
- The lesion to be biopsied is within the anatomic confines of the oropharynx (i.e. above the epiglottis).
- Tissue samples for biomarker analysis of the required 4 mm size are able to be obtained from both the lesion and an area of visually normal appearing tissue adjacent to but 1 cm distant from the lesion.
-
-
In this situation, randomization will be placed on hold until the following criteria are met:
- Normal organ and marrow function is confirmed.
- There is histologic confirmation of squamous cell carcinoma.
- It has been determined that surgical excision will be the first line standard of care treatment and the end of study tissue samples will be obtained in conjunction with that surgery.
Because these patient's lesions are not accessible to end of study tissue sample collection in the outpatient clinic setting, the only way to obtain those samples is in conjunction with standard of care surgical excision of the lesion. If the first line of treatment will be non-surgical, the patient will be considered a screen failure. Under no circumstances will DL biopsy be used for the sole purpose of collecting tissue samples for biomarker analysis.
-
Patients who have already had a diagnostic biopsy:
- The baseline tissue samples for biomarker analysis will be collected in the outpatient clinic setting as a "for research purposes only" procedure. The samples may not be collected until it has been determined that the participant meets all eligibility criteria for this protocol.
-
End of study tissue sample collection:
-
If surgical excision will be the patient's first line treatment, the end of study tissue samples for biomarker analysis will be collected in conjunction with that surgery. If, for any reason, the patient's surgery is delayed beyond Day 26, the end of study tissue samples may be collected in the outpatient clinic setting.
-
If the patient's first line of treatment will not be surgical excision, the end of study tissue samples for biomarker analysis will be collected in the outpatient clinic setting prior to initiation of the non-surgical treatment.
- Participant is able to complete a minimum of 10 days of study agent dosing prior to initiation of definitive treatment for their cancer
- Participant is scheduled for an end of study biopsy within 22 days of starting study agent and within 52 days of their study screening visit; (if the participant is scheduled for surgical excision of the tumor and the surgery is delayed for any reason after the participant has started taking the study agent, study agent dosing may be extended up to a maximum of 25 days without compromising the evaluability of the end of study biomarkers)

In addition, the effects of ACTOplus Met XR on the developing human fetus at the recommended therapeutic dose are unknown. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her study physician immediately.)
