Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention consisits of a treatment period of 7 days (+1 day visit window). Eligible subjects randomised to the treatment arm will self-administer (orally rinse, swish, and gargle for 60 seconds, and expectorate) at home. Subjects will self-administer 8 mL LBS-020 (150ug/ml) orally five times a day every 3h ± 2h, preferably before meals. Subjects will be provided with sufficient product (vials) for self-administering five times a day for 8 days. At end of treatment phase, subjects will return all unused product. Furhter, subjects will be asked to complete a daily diary for monitoring of the treatment phase.

Outcomes
Primary outcome [1] 319681 0
VAS score assessing subject's mouth dryness
Timepoint [1] 319681 0
Visit 3 (end of treament period)
Secondary outcome [1] 369138 0
Treatment-emergent adverse events. The investigator will report all directly observed adverse events and all adverse events spontaneously reported by a study subject. Each study subject will be questioned about adverse events at each scheduled study visit. The type of question asked should be open-ended (e.g., “Have you had any new health problems?” or similar type of query). Examples of Adverse Events include significant or unexpected worsening or exacerbation of the condition/indication under study; exacerbation of a chronic or intermittent pre-existing condition including either an increase in frequency and/or intensity (grade) of the condition; New conditions detected or diagnosed after investigational product administration even though they may have been present prior to the start of the study; Signs, symptoms, or the clinical sequelae associated with a suspected interaction of the investigational product with a concomitant medication; Signs, symptoms, or the clinical sequelae associated with a suspected overdose of either investigational product or a concurrent medication.

Summary
Brief summary
The purpose of this study is to test a medication called LBS-020 in addressing dry mouth in patients who have undergone treatment for cancer.

Who is it for?
You may be eligible for this study if you are aged 18 or over, have a history of treated head and/or neck cancer, and have been diagnosed with dry mouth (also known as xerostomia).

Study details
Participants in this study will be randomised by chance into two groups. Both groups will use a mouthwash 5 times per day for 7 days. One group will use the intervention treatment which includes a medication called LBS-020. The other group will use an identical looking mouthwash that does not include the medication. All participants will complete a number of scales about their symptoms.

It is hoped this study will demonstrate the intervention treatment can ameliorate many of the symptoms experienced by patients suffering from radiation/chemotherapy-induced chronic xerostomia.
