Outcome Measures

Primary Outcomes (4)

  • Difference in Numeric Rating Scale score of discomfort of daily breathlessness between active treatment and placebo

    Numeric rating scale score range 0-10. Higher score reflects higher discomfort of breathlessness

    Assessed daily in the baseline period and through both treatment periods. Up to 70 days

  • Difference in Numeric Rating Scale score of breathlessness interference of daily activities between active treatment and placebo

    Numeric rating scale score range 0-10. Higher score reflects more breathlessness interference on daily activities

    Assessed daily in the baseline period and through both treatment periods. Up to 70 days

  • Correlation between breathlessness rated on a daily numeric rating scale in relation to amount of THC blood level of the active treatment period

    Numeric rating scale score range 0-10. Higher score reflects higher discomfort of breathlessness

    Assessed daily in the baseline period and through both treatment periods. Up to 70 days

  • Correlation between breathlessness interference of daily activities rated on a numeric rating scale in relation to amount of THC blood level of the active treatment period

    Numeric rating scale score range 0-10. Higher score reflects more breathlessness interference on daily activities

    Assessed daily in the baseline period and through both treatment periods. Up to 70 days

Secondary Outcomes (12)

  • Difference in Multidimensional Dyspnea Profile questionnaire score between active treatment and placebo period

    Baseline (T1; day 1) and after each treatment period (T4; day 28, T7; day 70)

  • Difference in COPD Assessment Test questionnaire score between active treatment and placebo period

    Baseline (T1; day 1) and after each treatment period (T4; day 28, T7; day 70)

  • Difference in Chronic Respiratory Disease Questionnaire score between active treatment and placebo period

    Baseline (T1; day 1) and after each treatment period (T4; day 28, T7; day 70)

  • Difference in Hospital Anxiety and Depression Scale questionnaire score between active treatment and placebo period

    Baseline (T1; day 1) and after each treatment period (T4; day 28, T7; day 70)

  • Difference in Medical Research Council Dyspnea Scale questionnaire score between active treatment and placebo period

    Baseline (T1; day 1) and after each treatment period (T4; day 28, T7; day 70)

  • +7 more secondary outcomes

Other Outcomes (2)

  • Difference in clinical parameters between active treatment and placebo period using a yet unspecified continuous monitoring device.

    Baseline (T1; day 1) and after each treatment period (T4; day 28, T7; day 70)

  • Difference in stand-to-sit-test between active treatment and placebo

    Baseline (T1; day 1) and after each treatment period (T4; day 28, T7; day 70)

Study Arms (2)

Dronabinol 20 mg, then placebo

EXPERIMENTAL

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.

PLACEBO COMPARATOR

In this arm, the study subject will first 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. After a wash out period of 2 weeks, study subject will 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.

Masking Details
An external party will manage the randomization process, assigning participants equally to either the active treatment or placebo groups in a 1:1 ratio. The randomization will be conducted using www.sealedenvelope.com and will incorporate varying block sizes, such as 4, 6, and 8 participants per block. Consequently, each medication container will be labeled with a unique participant number.
