Who is this study for? Adult patients with suspected Head and Neck Squamous Cell Carcinoma
What treatments are being studied? Atezolizumab
Status: Recruiting
Location: See location...
Intervention Type: Biological
Study Type: Interventional
Study Phase: Phase 2
SUMMARY

To determine the effect of neoadjuvant atezolizumab alone or in combination with other immune modulating agents on T-cell infiltration in advanced SCCHN. To determine the impact of neo-adjuvant immunotherapy on surgical outcomes.

Eligibility
Participation Requirements
Sex: All
Minimum Age: 18
Healthy Volunteers: f
View:

• Patients must have clinically suspected SCCHN that is amenable to surgical resection with therapeutic intent

• Be willing and able to provide written informed consent/assent for the trial

• Be \>=18 years of age on day of signing informed consent.

• Agree to research analysis of an existing pre-treatment biopsy available that was obtained within 90 days prior to the day of consent or agree to a new biopsy for research (or clinical diagnosis) within the screening window. Needle biopsies must be at least 20 Gauge in diameter

• Have a performance status of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) performance scale

• Demonstrate adequate organ function as defined below. All screening labs should be performed within 14 days of treatment initiation

‣ Absolute neutrophil count (ANC) \>=1,500 /microliter (mcL)

⁃ Platelets \>=100,000 / mcL

⁃ Hemoglobin \>= 9 g/dL

⁃ Lymphocyte count \>= 500/mcL

⁃ White blood count \>=3,000/mcL or \<=14,000/mcL

⁃ Serum creatinine =\< 1.5 x upper limit of normal (ULN) OR ≥50 mL/min creatinine clearance by Cockcroft-Gault formula for participants in whom, in the Investigator's judgment, serum creatinine levels do not adequately reflect renal function. \* Creatinine clearance should be calculated per institutional standard

⁃ Serum total bilirubin =\< 1.5 x ULN OR direct bilirubin =\< ULN for subjects with total bilirubin levels \> 1.5 ULN

‣ \* Excluding Gilbert's syndrome. Participants with Gilbert's syndrome will be eligible for the study. The diagnosis of Gilbert's syndrome is suspected in people who have persistent, slightly elevated levels of unconjugated bilirubin (\<= 3.0 x ULN) without any other apparent cause. A diagnosis of Gilbert's syndrome will be based on the exclusion of other diseases on the basis of the following criteria: i. Unconjugated hyperbilirubinemia noted on several occasions ii. No evidence of hemolysis (normal hemoglobin, normal haptoglobin levels, reticulocyte count), and lactate dehydrogenase iii. Normal liver function tests iv. Absence of other diseases associated with unconjugated hyperbilirubinemia

⁃ Aspartate aminotransferase (AST) \[serum glutamic-oxaloacetic transaminase (SGOT)\] and alanine aminotransferase (ALT) \[serum glutamate pyruvate transaminase (SGPT)\] =\< 3 x ULN

⁃ Albumin \>= 2.5 mg/dL

⁃ International normalized ratio (INR) or prothrombin time (PT) =\< 1.5 x ULN unless subject is receiving anticoagulant therapy as long as PT or partial thromboplastin time (PTT) is within therapeutic range of intended use of anticoagulants

⁃ Activated partial thromboplastin rime (aPTT) =\< 1.5 x ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants

• Female subject of childbearing potential should have a negative urine or serum pregnancy within 7 days prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required

• Female subjects of childbearing potential must be willing to use an adequate method of contraception for the course of the study through 5 months after the last dose of study medication.

• Male subjects must agree to use an adequate method of contraception and refrain from donating sperm, starting with the first dose of study therapy through 5 months after the last dose of study therapy

‣ Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject.

Participants
Target number of participants: 55
Treatments
Experimental: Atezolizumab Monotherapy
Participants will receive 840mg of atezolizumab over 15 days prior to definitive surgery.
Experimental: Atezolizumab (Adjuvant)
Participants will receive 840mg of atezolizumab over 15 days prior to definitive surgery. The first 9 participants in Arm A (atezolizumab monotherapy) will also receive adjuvant atezolizumab 16 weeks after standard of care surgery and radiation, or chemoradiation therapy, at a fixed dose of 1200 mg IV every 3 weeks for an additional 12 cycles.
Experimental: Atezolizumab + Tiragolumab
Participants will receive 840 mg of atezolizumab IV and 600 mg of Tiragolumab during the 15-day neoadjuvant period prior to definitive surgery.
Experimental: Atezolizumab + Tocilizumab
Participants will receive 840 mg of atezolizumab IV and 6 mg/kg of Tocilizumab during the 15-day neoadjuvant period prior to definitive surgery.
