Taste Receptors Regulation in CF Patients

Status Recruiting

Clinical Trial Summary

The project is intended to be realised in two phases. In the first stage, a case control study will be performed. In the second phase, double-blind, placebo controlled cross-over study will be conducted. The first stage it to compare innate immunity activation and Pseudomonas aeruginosa (Pa) expression between Pa positive and negative patients. In the second phase the effects of inhaled lactizole- TAS3R inhibitor will be assessed.

Clinical Trial Description

Three visits have been planned during the entire study. During the first visit, all patients included in the study will have the following procedures: questionnaire tests, lung function tests, taste perception tests (gustometry) and exfoliative cytology of the nasal mucosa.

Patients with confirmed Pseudomonas aeruginosa presence in the airways will be randomly assigned to the Lactizole-Placebo group and the Placebo-Lactizole group, with a recommendation to take laktizol (3 ml) for 3 weeks at the concentration determined during the preliminary examination, in the nebulization 2 times per day) or placebo (3ml 0.9% NaCl solution in nebulization 2 once a day). The first nebulization of the solution issued during the visit will take place during the visit; each patient will undergo a clinical and spirometric assessment after 20 minutes of observation from completed nebulization.

During the second visit (after 4 weeks from visit 1), the first visit procedures will be repeated for all patients. Patients in the Lactizole-Placebo group will be recommended to take a placebo for 4 weeks (3 ml of 0.9% NaCl solution in nebulization 2 once a day); on the other hand, patients from the Placebo-Lactizole group will be advised to take lactisol for 4 weeks (3 ml of the solution in the concentration determined during the preliminary examination, in the nebulization 2 once a day). The first nebulization of the solution issued during the visit will take place during the visit; each patient will undergo a clinical and spirometric assessment after 20 minutes of observation from completed nebulization.

During the third visit (after 4 weeks from visit 2), the first visit procedures will be repeated for all patients. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
