Trial Outcomes & Findings for Study of TAK-935 as an Adjunctive Therapy in Adult Participants With Complex Regional Pain Syndrome (CRPS) (NCT NCT03990649)

NCT ID: NCT03990649

Last Updated: 2021-07-15

Results Overview

The 24-hour average pain intensity was calculated from current pain intensity scores collected three times a day as measured by the electronic pain diary daily using NPS. NPS is an 11-point scale, where scores range from 0-10, 0= no pain to 10 = most pain imaginable. Negative change from Baseline indicated improvement.

Participant Flow

Participants took part in the study at three investigative sites in United Kingdom (UK) from 23 July 2019 to 28 October 2020.

Participants with a diagnosis of chronic complex regional pain syndrome (CRPS) were enrolled to receive soticlestat or placebo in Part A (Double-blind \[DB\] Treatment Period) and soticlestat in Part B (Open-label \[OL\] Treatment Period). Following completion of the Part A, participants had an option to continue into Part B.

Double-Blind Treatment Period - Part A: Placebo
Soticlestat matching placebo tablets, orally, twice daily (BID) for Weeks 1, 2 and 3 in Double blind Titration Period. Soticlestat matching placebo tablets, orally BID for 12 weeks in Double blind Maintenance Period. Taper period (if participant did not continue to Part B): Dose of soticlestat matching placebo tablets was reduced to next lower dose every 3 days (maximum 6 days) until discontinuation.
Double-Blind Treatment Period - Part A: Soticlestat
Soticlestat, tablet, orally, 100 mg BID for Week 1, followed by 2×100 mg tablets, soticlestat, orally BID for Week 2, further followed by 3×100 mg tablets, soticlestat, orally BID for Week 3. Dose was uptitrated every week based on safety and tolerability. Part A (Double blind Maintenance Period): 3×100 mg tablets, soticlestat, orally BID for 12 weeks. Dose was adjusted during Maintenance Period due to safety and tolerability. Taper Period (if participant did not continue to Part B): Dose of soticlestat was reduced to next lower dose every 3 days (maximum 6 days) until soticlestat was discontinued.
Open-Label Extension Period - Part B: Soticlestat
Soticlestat, 2×100 mg tablets, orally, BID for Week 1, followed by 3×100 mg tablets, soticlestat, orally, BID for Week 2. Dose was uptitrated every week based on safety and tolerability. Part B (Open label extension: Maintenance Period): 3×100 mg tablets, soticlestat, orally, BID for 12 weeks. Dose was adjusted during Maintenance Period due to safety and tolerability. Taper Period: Dose of soticlestat was reduced to next lower dose every 3 days (maximum 6 days) until soticlestat was discontinued.

PRIMARY outcome

Timeframe: Baseline and Week 15

Population: Full Analysis Set for included all participants who were randomized, received at least 1 dose of study drug, and had at least one valid post-baseline value for the assessment of average 24-hour pain score. The data is reported for Part A in this outcome measure. Overall number of participants analyzed are the number of participants with data available for analyses.

The 24-hour average pain intensity was calculated from current pain intensity scores collected three times a day as measured by the electronic pain diary daily using NPS. NPS is an 11-point scale, where scores range from 0-10, 0= no pain to 10 = most pain imaginable. Negative change from Baseline indicated improvement.

The data is reported for Part A in this outcome measure. Number analyzed are the number of participants with data available for analyses in the given category (domain).

PROMIS-29 (v2.1) is a health-related quality of life survey assessing 7 domains with 4 questions on a 5-point Likert scale. Total raw domain scores are converted into T-scores from a reference population: Depression: 1=never to 5=always, T-scores:41.0-79.4; Physical function: 1=unable to do to 5=without any difficulty, T-scores: 22.5-57.0; Anxiety: 1=never to 5=always, T-scores: 40.3-81.6; Pain interference: 1=not at all to 5=very much, T-scores: 41.6-75.6; Fatigue: 1=not at all to 5=very much, T-scores: 33.7-75.8; Sleep disturbance: 1=very much to 5=not at all, T-scores: 32.0-73.3; Ability to participate in social roles or activities: 1=always to 5=never, T-scores: 27.5-64.2. High scores signify more of domain being measured. Thus, on symptom-oriented domains, higher scores=worse symptomatology and a negative change from Baseline indicates improvement. On function-oriented domains, higher score=better functioning and a positive change from Baseline indicates improvement.

Timeframe: Week 15

Population: Full Analysis Set for included all participants who were randomized, received at least 1 dose of study drug, and had at least one valid post-baseline value for the assessment of average 24-hour pain score. The data is reported for Part A in this outcome measure.

The PGIC is a 7-point Likert scale to address the following question: Since beginning treatment at this clinic would you describe any changes (if any) in activity, limitations, symptoms, emotions and overall quality of life related to your painful condition compared to before treatment? Participants select from scale range of 1-7: very much improved (1); much improved (2); minimally improved (3); no change (4); minimally worse (5); much worse (6); very much worse (7). Only categories with at least 1 participant were reported.

SECONDARY outcome

Timeframe: Baseline and Week 15

Population: Full Analysis Set for included all participants who were randomized, received at least 1 dose of study drug, and had at least one valid post-baseline value for the assessment of average 24-hour pain score. The data is reported for Part A in this outcome measure. Overall number of participants analyzed are the number of participants with data available for analyses.

Signs and symptoms reflecting the sensory, vasomotor, sudomotor/edema, and motor/trophic disturbances of CRPS had been incorporated into a clinically feasible CSS. Total CSS is a 16-point score which was calculated by the number of "yes" answers to the questions on the 8 symptoms and 8 signs when all 16 questions were answered. Negative change from Baseline indicates improvement.
