NCT04998305

Brief Summary

The primary objective of the study is to demonstrate the safety and potential efficacy of TJ-68 for improving muscle cramps in participants with ALS based on a two-site, randomized, placebo-controlled double-blind multi-period crossover (N-of-1) study design.

Outcome Measures

Primary Outcomes (1)

  • Visual Analog Scale (MCS-VAS) Score

    This is designed to measure improvements in muscle cramps. MCS-VAS indicates the level to which muscle cramps affect overall daily activity. The score ranges from 0 to 10; 0 indicates no interference and 10 indicates severe interference with overall daily activity. MCS-VAS will be administered by a trained evaluator to reduce recall bias and lack of insight, which can limit subjective assessments. To minimize carryover effects, results reflect the average of the scores taken at the second week of each treatment period.

    Assessed at Baseline, Week 2, Week 5, Week 8 and Week 11; Week 2 reported

Secondary Outcomes (6)

  • Overall Muscle Cramp Scale (MCS) Score

    Assessed at Baseline, Week 2, Week 5, Week 8 and Week 11; Week 2 reported

  • Self-reported Cramp Pain Score

    Assessed at Baseline, Week 2, Week 5, Week 8 and Week 11; Week 2 reported

  • ALSFRS-R Score

    Assessed at Baseline, Week 2, Week 5, Week 8 and Week 11; Week 2 reported

  • Clinical Global Impression of Changes (CGIC) Score

    Assessed at Baseline, Week 2, Week 5, Week 8 and Week 11; Week 2 reported

  • ALSAQ-5 (Quality of Life Questionnaire) Score

    Assessed at Baseline, Week 2, Week 5, Week 8 and Week 11; Week 2 reported

  • +1 more secondary outcomes

Study Arms (2)

Treatment sequence TJ-68-Placebo-Placebo-TJ-68

EXPERIMENTAL

Employing an N-of-1, crossover design, each participant in the TJ-68 clinical trial will serve as his/her control. The participation will last for 11 weeks - four, 2-week treatment periods with 1-week washout (WO) period between each treatment period. Participants (n=13) will be randomized to the following treatment sequences: TJ-68, placebo, placebo, TJ-68 (1 week WO between each treatment period)

Drug: TJ-68Drug: Placebo

Interventions

TJ-68DRUG

For two periods (one period = 2 weeks) during the 11-week participation, participants will take 2.5 g of TJ-68 for three times per day before meals. It will be administered by dissolving 2.5 g of TJ-68 powder in 1 oz. of lukewarm water.
