Topical Aldara (Imiquimod) for Oral Cancer

• Status: Recruiting
• Trial end date: 2023-06-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this research study is to find out what effects, good and/or bad, topical application of the drug Aldara will have on patients and on their oral cancer. Aldara is a drug that activates toll-like receptor (TLR) in oral cancer cells causing self-destruction of tumor cells. It also activates immune cells to attack and eliminate cancer cells. Aldara is currently approved by the Food and Drug Administration (FDA) for treatment of skin cancer and melanoma. Its use in this study is 'off-label' (use of a drug approved by FDA for skin cancer to treat oral cancer in this study).

To assess the preliminary efficacy of topical imiquimod in neoadjuvant setting in patients with early-stage oral squamous cell carcinoma as determined by best response rate (CR and PR). To assess local and systemic safety and tolerability by CTCAE v5 criteria. To explore the effect of imiquimod on the tumor immune microenvironment by performing quantitative multiplex immunofluorescence.

Criteria

Inclusion Criteria:

• Previously untreated and biopsy confirmed oral squamous cell carcinoma (OSCC)

• Clinical (TNM) stage I or II

• Age >= 18 years

• Eastern Cooperative Oncology Group (ECOG) =< 2

Exclusion Criteria:

• Patients associated with prior therapy requiring treatment with systemic immunosuppressive treatments with the exception of vitiligo, childhood asthma that has resolved, residual endocrinopathies requiring replacement therapy, or psoriasis that does not require systemic treatment

• Treatment with any other investigational agents

• Requirement for immunosuppressive intraoral topical or systemic corticosteroids prior to the study

• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements

• HIV positive patients on combination antiretroviral therapy

• Have evidence of any other significant oral mucosal condition, clinical disorder, physical examination finding, or laboratory finding that, as judged by the investigator, makes it undesirable for the patient to participate in the study

• Pregnant women are excluded from this study because imiquimod may have adverse effect on the fetus (FDA pregnancy risk category C). Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with imiquimod, breastfeeding should be discontinued if the mother is receiving study treatment

• Male patients unwilling or unable to comply with pregnancy prevention measures

• Subjects not receiving initial surgical treatment at Columbia University Irving Medical Center (CUIMC).
