Intervention / Treatment
Detailed Description
The Dreamland study is a two-arm, parallel-group, individually randomized (1:1 allocation ratio), controlled by disease stage, participant and investigator blinded, single-site superiority trial of oral cannabis extract (CBD). CBD will be given orally starting at 10 mg daily and up-titrated to a maximum dose of 150 mg daily. Dose up-titration will be based on clinical response or side effects, whichever comes first. After 63 days of treatment, gradual withdrawal will be performed during one week. Then, at 70 days, there will be an open-label extension wherein all participants from control group will be offered a course of CBD according to the same previous protocol.
This research intends to :
- Assess whether the daily use of CBD, for nine weeks, will reduce the pain level of these women.
- Assess whether the daily use of CBD, for nine weeks, will modify pain threshold.
- Assess whether the daily use of CBD, for nine weeks, will interfere in psychological symptoms.
- Assess the possible adverse effects of using CBD

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Cannabis Derivatives
Cannabis Derivatives (98% CBD, 2% THC) will be given orally starting at 10 mg daily and up-titrated to a maximum dose of 150 mg daily. Dose up-titration will be based on clinical response or side effects, whichever comes first. After 63 days of treatment, gradual withdrawal will be performed during one week. All patients will take hormonal contraceptives, preferably progestagen-only. All participants will perform invasive and non-invasive procedures with the nursing team. The invasive will be blood collections, to evaluate laboratory parameters. The non-invasive ones refer to the measurement of height, weight, body temperature, and sleep pattern, as will pain threshold. In addition, they will be monitored through weekly self-assessment scales, applied remotely, electronically (cell phones or computers), with an estimated duration of ten minutes each, which will have their responses recorded in an electronic database, by the study coordination team. |
CBD 10 mg (up-titrated until 150mg or adverse effects) daily for 9 weeks
All participants will be given hormonal contraceptive.
|
Placebo Comparator: Placebo
Placebo will be given at the same protocol described before. The bottle, label, color and density of the contents will be the same. All patients will take hormonal contraceptives, preferably progestagen-only. Then, at 70 days, there will be an open-label extension wherein all participants from control group will be offered a course of active treatment according to the same previous protocol. All participants will perform invasive and non-invasive procedures with the nursing team. The invasive will be blood collections, to evaluate laboratory parameters. The non-invasive ones refer to the measurement of height, weight, body temperature, and sleep pattern, as will pain threshold. In addition, they will be monitored through weekly self-assessment scales, applied remotely, electronically (cell phones or computers), with an estimated duration of ten minutes each, which will have their responses recorded in an electronic database, by the study coordination team. |
All participants will be given hormonal contraceptive.
Placebo 10 mg (up-titrated until 150mg or adverse effects) daily for 9 weeks
