- Radiation can cause the parotid salivary glands to make less saliva (dry mouth). This can cause problems like infections and tooth decay. Researchers hope a new drug can help people with dry mouth caused by radiation.
- To examine the safety of AAV2hAQP1 gene therapy. To see if the drug increases saliva in people whose parotid glands have had radiation.
- People at least 18 years of age with a history of radiation therapy for head and neck cancer.
Participants will be screened in 2 visits with:
- medical history
- physical exam
- saliva collections
- sialogram. A substance is injected in the parotid gland and X-rays are taken.
- non-drug infusion
- IV dose of glycopyrrolate to stop saliva
3-day hospital stay: Participants will get the gene infusion. The AAV2hAQP1 will be in a solution in a syringe. It will be slowly pushed through an opening into the gland inside your mouth.
10 outpatient visits over 3 years. These may include:
- repeats of screening tests
- blood and urine tests
- oral and head and neck exams, including a thin scope in the airway
- small piece of skin taken
- small piece of parotid tissue taken by either: a small video-scope in the parotid duct that also takes pictures or by a small needle guided by ultrasound
- scans. Participants lie in a machine or a scanner The machine may feel close to the body or face. . For some, a substance will be injected in a vein or put in the mouth.
- Participants will keep a diary about how they feel before and after the therapy.
- oral microbiome gingival and buccal swab
