Brief Summary
This study will assess the efficacy and safety of bilateral intra-parotid administration of AAV2-hAQP1 in adults with Grade 2 or Grade 3 radiation-induced late xerostomia.
Eligibility Criteria
Inclusion Criteria: * Completed beam radiation therapy for head and neck cancer at least 3 years prior to the first screening visit * No history of recurrent head and neck cancer, parotid gland cancer, or a second primary cancer, except for treated basal cell or squamous cell carcinoma of the skin or in situ cervical carcinoma * An unstimulated whole saliva flow rate (mL/min) \>0 (i.e., at least one drop of saliva in the collection tube) * A stimulated whole saliva flow rate (mL/min) within a specified range after mechanical stimulation by chewing * Average screening XQ Total Score at or above a specified threshold * No evidence of head and neck cancer, defined as a negative otolaryngology exam and a negative computed tomography (CT) scan of the head, neck, and chest with contrast. If a participant has had a magnetic resonance imaging (MRI) study, CT scan, positron emission tomography (PET), or fluorodeoxyglucose-positron emission tomography (FDG-PET) scan of the head, neck, and chest
