Study Details

Study Description

Brief Summary

The purpose of this research is to evaluate whether the administration of atezolizumab before surgical resection of your tumor is feasible and to evaluate the treatment response, safety, and tolerability of atezolizumab.

Condition or DiseaseIntervention/TreatmentPhase
Phase 2

Detailed Description

Primary Objective:

Arms and Interventions

ArmIntervention/Treatment
Experimental: Atezolizumab

Subjects will receive neoadjuvant atezolizumab intravenous (IV) infusion at a fixed dose of 1200 mg on Day 1 (+/- 3 days) of each 21-day cycle for a total of 3 doses prior to surgery, unless there is clinical or radiographic evidence of disease progression.

  • Outcome Measures

    Primary Outcome Measures

    1. Percentage of patients who complete neoadjuvant therapy and surgical resection [1 Day]

      Percentage of patients that are able to complete 3 cycles of neoadjuvant neoadjuvant atezolizumab, followed by surgical resection will be measured.

    Secondary Outcome Measures

    1. Objective response rate [After cycle 3 (duration of each cycle 21 days)]

      Objective response rate will be measured based on RECIST v1.1 criteria at baseline, after cycle 2, and at the time or surgery

    2. Pathological response rate [After cycle 3 (duration of each cycle 21 days)]

      Pathological response will be assessed by local pathological review at baseline, after cycle 2, and and at the time or surgery Patients with no viable tumor seen will be classified as a complete pathological response. Patients with < 10% of viable tumor will be classified as a major pathological response.

    Eligibility Criteria

    Criteria

    Ages Eligible for Study:
    18 Years and Older
    Sexes Eligible for Study:
    All
    Accepts Healthy Volunteers:
    No
    Inclusion Criteria:
    1. Signed Informed Consent Form

    2. Age ³ 18 years at time of signing Informed Consent Form

    3. Histologically or cytologically confirmed squamous cell carcinoma

    4. Measurable disease per RECIST v1.1

    • Note that protocol specified imaging is not necessary to fulfill this criterion. For example, a patient presenting with a visible 4cm primary lesion who has obviously RECIST evaluable disease may be considered eligible prior to baseline imaging stipulated in the protocol.
    1. Availability of a representative tumor specimen that is suitable for determination of PD-L1 immunohistochemical stain evaluation.

    2. Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1

    3. Adequate hematologic and end-organ function appropriate for surgery as determined by routine preoperative evaluation. If liver function, renal function and hematologic laboratory test results are within limits acceptable for elective surgery. Laboratory results that will need to be obtained within 28 days prior to initiation of study treatment:

    • aspartate aminotransferase (AST), alanine aminotransferas (ALT), total bilirubin, and alkaline phosphatase (ALP) £ 2.5 x upper limit of normal (ULN.).

    • Thyroid-stimulating hormone (TSH) < 13, Patients with a history of a high TSH who are receiving levothyroxine replacement at the time of eligibility evaluation and have no clinical evidence of hypothyroidism are eligible.

    1. For patients receiving therapeutic anticoagulation: stable anticoagulant regimen

    2. Negative hepatitis B surface antigen (HBsAg) test at screening

    3. For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods, as defined below: Women must remain abstinent or use contraceptive methods with a failure rate of < 1% per year during the treatment period and for 5 months after the final dose of atezolizumab.

    A woman is considered to be of childbearing potential if she is postmenarchal, has not reached a postmenopausal state (³ 12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus). The definition of childbearing potential may be adapted for alignment with local guidelines or requirements.

    Examples of contraceptive methods with a failure rate of < 1% per year include bilateral tubal ligation, male sterilization, hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices.

    The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation

    1. For men: Agreement to remain abstinent (refrain from heterosexual intercourse) or use a condom, and agreement to refrain from donating sperm, as defined below:

    With a female partner of childbearing potential or pregnant female partner, men must agree to remain abstinent or use a condom during the treatment period and for 5 months after the final dose of atezolizumab to avoid exposing the embryo. Men must agree to refrain from donating sperm during this same period
