Clinical Trial Summary

This phase II trial tests how well cemiplimab works in treating basal cell carcinoma of the head and neck that has spread to nearby tissue or lymph nodes (locally advanced) before surgery (neoadjuvant). Cemiplimab is a human recombinant monoclonal IgG4 antibody that may allow the body's immune system to work against tumor cells. Giving cemiplimab before surgery may make the tumor smaller and make it easier to remove.

Description:

PRIMARY OBJECTIVE:

I. To assess treatment response of locally advanced basal cell carcinoma (BCC) of the head and neck (BCCHN) in the neoadjuvant, presurgical setting.

SECONDARY OBJECTIVES:

I. To assess functional organ preservation with neoadjuvant Cemiplimab therapy. II. To assess pathologic response. III. To assess safety of neoadjuvant therapy. IV. To assess changes in quality of life.

EXPLORATORY OBJECTIVE:

I. To assess treatment-related changes in the immune microenvironment related to functional changes in immune cell composition.

OUTLINE:

Patients receive cemiplimab intravenously (IV) over 30 minutes on day 1 of each cycle. Treatment repeats every 21 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients with progressive disease may transition to standard of care (SOC) hedgehog inhibitor (HHI) therapy. Patients undergo computed tomography (CT) or magnetic resonance imaging (MRI) scans and collection of blood samples throughout the trial. Patients also undergo biopsies during screening and on study.

Upon completion of study treatment, patients are followed up at 3 months and 6 months.

"Women of reproductive potential" 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 months of amenorrhea in a woman over 45 in the absence of other biological or physiological causes.

• Informed Consent: All subjects must be able to comprehend and sign a written informed consent document

Exclusion Criteria:

• Prior radiation therapy within the past 6 months for this target cancer documented by surgeon at Visit 1, Day 0 initial assessment. (Prior surgical resection to area/tumor is acceptable)

• Any history of allergy to the study drug components

• Any concurrent malignancies: exceptions include- basal cell carcinoma of the skin at another site, chronic lymphocytic leukemia, melanoma in situ, squamous cell carcinoma of the skin of a secondary location, superficial bladder cancer or in situ cervical cancer that has undergone potentially curative therapy. Patients with a history of other prior malignancy must have been treated with curative intent and must have remained disease-free for 2 years post-diagnosis

• Any unresolved toxicity National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version (v) 5.0 Grade >= 2 from previous anticancer therapy with the exception of alopecia, vitiligo, and the laboratory values defined in the inclusion criteria. Patients with Grade >= 2 neuropathy will be evaluated on a case-by-case basis after consultation with the Study Physician. Patients with irreversible toxicity not reasonably expected to be exacerbated by treatment with anti-PD1 therapy may be included only after consultation with the Study Physician.

• Any Subjects with a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 28 days of study drug administration., or a prior history of allogenic organ transplantation

• Any diagnosis of a significant connective tissue disorder as determined by the treating surgeon or medical team

• Patients must not be receiving any other investigational agents

• Receipt of a live attenuated vaccine within 30 days prior to the first dose of drug on trial

• Uncontrolled intercurrent illness, including but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, interstitial lung disease, serious chronic gastrointestinal conditions associated with diarrhea, or psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring AEs or compromise the ability of the patient to give written informed consent

• Patients must not be pregnant or breastfeeding

• Active infection including tuberculosis (TB) (clinical evaluation that includes clinical history, physical examination and radiographic findings, and TB testing in line with local practice), hepatitis B (known positive hepatitis B virus [HBV] surface antigen [HBsAg] result), hepatitis C, or human immunodeficiency virus [positive HIV 1/2 antibodies]). Patients with a past or resolved HBV infection (defined as the presence of hepatitis B core antibody [anti-HBc]and absence of HBsAg) are eligible. Patients positive for hepatitis C (HCV) antibody are eligible only if polymerase chain reaction is negative for HCV ribonucleic acid (RNA)
