A Study of Concurrent Chemoradiation in Combination With or Without PD1 Inhibitor AB122 Adenosine 2a Receptor / Adenosine 2b Receptor Inhibitor AB928 Therapies in Locally Advanced Head and Neck Cancers (PANTHEoN)
A Phase Ib Study of Concurrent Chemoradiation in Combination With or Without PD1 Inhibitor AB122 Adenosine 2a Receptor / Adenosine 2b Receptor Inhibitor AB928 Therapies in Locally Advanced Head and Neck Cancers (PANTHEoN)
The purpose of this study is to test the safety and tolerability of chemotherapy and radiation in combination with the investigational study drugs zimberelimab (AB122) and etrumadenant (AB928) in subjects with a locally advances head or neck cancer. The study will also ask how the study drugs change the following:
- The microbiome that lives in the mouth and on the skin
- Immune cells as they respond to a skin wound
- Scarring (fibrosis) caused by radiation
After completing a screening phase, subjects will be assigned to one of three cohorts:
- Cohort 1: Subjects who will receive cisplatin, radiation and zimberelimab followed by zimberelimab only.
- Cohort 2: Subjects who will receive cisplatin, radiation, zimberelimab and etrumadenant followed by zimberelimab and etrumadent.
- Cohort 3: Subjects who will receive cisplatin and radiation followed by an observation period.
All three cohorts will be followed for a 24 months following the conclusion of the chemoradiation.

- Lymphocyte count ≥ 500/μL
- Albumin ≥ 25 g/L (2.5 g/dL)
Exclusion Criteria:
Participants are excluded from the study if any of the criteria below apply.
- Prior treatment for head and neck squamous cell carcinoma including systemic therapies, local therapies or radiation.
- Major medical or other conditions that might affect the study assays: major surgery or trauma in the past 28 days, known current pregnancy, poorly controlled diabetes (repeated glucose >250), history of or current clinically relevant coagulation abnormalities, as determined by the PI. Tracheostomy and feeding tube placement are permitted at any time.

Participants with asthma requiring intermittent use of bronchodilators (such as albuterol) will not be excluded from this study. Replacement therapy (e.g. thyroxine, insulin, or physiologic corticosteroid replacement for adrenal or pituitary insufficiencies) is not considered a form of systemic treatment and is allowed. This exclusion criteria applies only to Cohorts 1 and 2 but would be allowed on to Cohort 3.

- Cohort 2 only: Inability to swallow medications.
- Cohort 2 only: Malabsorption condition that would alter the absorption of orally administered medications.
- Evidence of inherited bleeding diathesis or significant coagulopathy at risk of bleeding (i.e., in the absence of therapeutic anticoagulation); INR or aPTT ≥ 1.5 ULN.

Treatment with therapeutic oral or intravenous (IV) antibiotics within 2 weeks prior to initiation of study treatment. Patients receiving prophylactic antibiotics (eg, to prevent a urinary tract infection or chronic obstructive pulmonary disease exacerbation) are eligible for the study.
a. Topical antibiotics are not permitted within 24 hours from the collection "Skin biopsy Pair 1" if the areas of application are anticipated to interfere with the anticipated sites of biopsies.
