Snížení dušnosti pomocí dronabinolu u pacientů s CHOPN (BONG)
BONG: Snížení těžké dušnosti pomocí dronabinolu u skupiny pacientů s těžkou a velmi těžkou chronickou obstrukční plicní nemocí – randomizovaná, dvojitě zaslepená, placebem kontrolovaná, zkřížená studie
This clinical trial examines whether Dronabinol, which contains the synthetic psychoactive compound tetrahydrocannabinol (THC), can alleviate severe breathlessness in patients with severe and very severe chronic obstructive pulmonary disease (COPD).

Detailní popis
This study is a randomized, controlled, double-blind, crossover trial evaluating the effectiveness of the pharmaceutical drug Dronabinol in patients with severe and very severe COPD.
The researchers will compare the effects of Dronabinol with a placebo (an identical-looking substance that contains no active drug) to determine if Dronabinol reduces breathlessness in COPD patients.
After enrollment, study subjects will undergo four weeks of treatment with both Dronabinol and the placebo in a blinded and randomized sequence. There is a two-week washout period between treatments. During these treatment phases, subjects will complete questionnaires about their daily experiences of breathlessness and wear a watch that records various health parameters.
The study includes eight visits: the initial enrollment and follow-up checks every two weeks. At these visits, subjects undergo tests for lung function and walking distance, and complete health status questionnaires. Additionally, blood samples for THC levels and hair samples for cortisol analysis are collected.

Experimentální: Dronabinol 20 mg, then placebo
In this arm, the study subject will first receive dronabinol 2.5 mg capsules. For two weeks the subject will titrate dose with one capsule corresponding to 2.5 mg dronabinol every other day until 20 mg. Doses are divided into three times a day. After up titration the subject will receive 20 mg daily treatment over a period of 2 weeks. After a wash out period of 2 weeks, study subject will receive placebo capsules (matching dronabinol 2.5 mg capsules). For two weeks the subject will titrate with one capsule every other day until 20 mg. Doses are divided into three times a day. After up titration the subject will receive 8 daily placebo capsules over a period of 2 weeks. |
Dronabinol 2.5 mg pr capsule. Titration up till 20 mg daily dose.
