Efficacy and Safety of VER-01 in the Treatment of Patients With Chronic Non-specific Low Back Pain

Study Overview

Conditions
Intervention / Treatment
Detailed Description
The study is divided into four phases: Phase A, B, C and D. All patients who have completed Phase A and for whom the investigator considers further participation to be safe shall begin Phase B. Phases C and D run in parallel, so that patients who have completed Phase B and for whom the investigator considers further participation to be safe can be assigned to one of the two phases.
Phases A and D follow a double-blind, placebo-controlled design, while Phase B and C have an open-label design.
The main goal of Phase A is to demonstrate the efficacy of VER-01 compared to placebo. In Phase B and C the main goal is the investigation of long-term safety of VER-01. In Phase D the primary objective is to demonstrate the maintenance of efficacy of VER-01 on a placebo-controlled basis.
The potential for dependence and abuse will be analyzed in all Phases (A,B,C,D), while the effect of abrupt drug withdrawal of VER-01 will be analyzed in Phase C and D.

The optimal dose is titrated on a patient-by-patient basis.
The maximum daily dose should not exceed 13 dose units (32.5 mg THC).

|
Placebo Comparator: Placebo

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Phase A: Efficacy based on pain reduction
Time Frame: Baseline up to 15 weeks
|
Change in average pain intensity compared to baseline on an 11-point Numerical Rating Scale (NRS, where 0=no pain to 10=worst pain imaginable) (mean value of study week 15 compared to the mean value of the seven-day run-in phase with daily documentation of pain intensity in the morning).
|
Baseline up to 15 weeks
|
Phase B: Safety based on occurrence of treatment-related AEs/SAEs
Time Frame: Up to 29 weeks
|
Safety and adverse reactions based on occurrence of treatment-related AEs/SAEs
|
Up to 29 weeks
|
Phase C: Safety based on occurrence of treatment-related AEs/SAEs
Time Frame: Up to 28 weeks
|
Safety and adverse reactions based on occurrence of treatment-related AEs/SAEs
|
Up to 28 weeks
|
Phase D: Maintenance of efficacy
Time Frame: Up to 4 weeks (from date of randomization R2 until the first day of treatment failure)
|
Time until treatment failure defined as the time in days from randomization to phase D (R2) until the first day of treatment failure.
Treatment failure is assessed by the daily calculated seven-day mean value of the pain score (11 point Numerical Rating Scale, NRS, where 0=no pain to 10=worst pain imaginable) in the morning during the treatment period, which must have deteriorated by at least 20% and at least one point compared to baseline (mean value of study week 43).
The first day of treatment failure is then the earliest day within this seven-day time window to which this criterion applies as a single day.
Furthermore, treatment failure is defined as a premature discontinuation of treatment for selected reasons.
|
Up to 4 weeks (from date of randomization R2 until the first day of treatment failure)
