Effect of AdhAQP1 on Salivary Flow in Patients Treated With Radiation for Head and Neck Cancer
NCT00372320 · View on ClinicalTrials.gov ↗
Study Summary
This study will examine whether the experimental drug AdhAQP1 can increase salivary flow in patients whose parotid glands have been exposed to therapeutic radiation for treatment of head and neck cancer. Radiation may damage the parotid glands (salivary glands located under the skin in front of the ear), leading to dry mouth, infections, excessive tooth decay, mouth sores, difficulty swallowing and pain. AdhAQP1 contains the human aquaporin-1 gene, which codes for a protein that works to transport water across cells, and a virus that normally can cause colds in humans, but is modified to render it ineffective. In animal experiments, AdhAQP1 has increased saliva production for a short time. Patients between 18 years of age or older who received radiation treatment for head and neck cancer at least 5 years before enrolling in this study, who have no evidence of recurrent tumor, who have dry mouth and who secrete abnormally low levels of saliva from the parotid glands may be eligible for this study. Candidates are screened with a medical history, physical examination, blood, urine and saliva tests, electrocardiogram (EKG), chest x-ray, MRI exam, gallium scan (a nuclear medicine test to look for inflammation in the salivary glands), technetium pertechnetate scan (a nuclear medicine test to examine salivary gland function), parotid sialogram (x-ray of parotid gland), PET and CT scans to look for signs of tumor and a skin biopsy to collect skin cells for use in immunological tests. Participants have a salt and sugar solution infused through a catheter (plastic tube) into both parotid glands. After 10 minutes, the solution drains into the mouth and is swallowed. Saliva is collected from the parotid glands at 6 and 24 hours after administration of the salt and sugar solution. Ten to 14 days later, patients are admitted to the NIH Clinical Center for up to 4 days for the following tests and procedures: * On the first day, administration, through a catheter, of the study d

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00372320
The ClinicalTrials.gov registry entry for NCT00372320 describes a study currently listed as completed. It is categorized as Phase 1, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 17 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Dental and Craniofacial Research (NIDCR), which has 60 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Parotid Salivary Dysfunction appearing as the primary indexed condition, and to 2 interventions — of which Gene Transfer is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00372320 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
