Safety Study of VM202 to Treat Amyotrophic Lateral Sclerosis

Phase 1
Completed
Conditions
Amyotrophic Lateral Sclerosis
Interventions
Registration Number
NCT02039401
Lead Sponsor
Helixmith Co., Ltd.
Brief Summary

The purpose of this study is to determine the safety and tolerability of intramuscular injections of VM202 at different injection sites in people with amyotrophic lateral sclerosis.

Detailed Description

A phase I/II, open label, single center study designed to assess the safety and tolerability of intramuscular injections of VM202 inpatients with Amyotrophic Lateral Sclerosis. Study enrollment will be staged. Enrollment will be halted after the sixth subject qualifies for treatment. A Data Safety Monitoring Board will conduct a safety evaluation after the first patient treated completes the Day 60 follow-up evaluation and the five other sequentially enrolled subjects complete at least the Day 30 follow-up. Enrollment will be suspended until a formal recommendation to proceed (or not proceed) is made by the Data Safety Monitoring Board.

Patients aged ≥ 21 years, but ≤ 75 years diagnosed with clinically definite, clinically probable, or clinically probable-laboratory supported Amyotrophic Lateral Sclerosis.

This study is not powered to detect differences in efficacy measures. However, descriptive statistics (N, mean, median, standard deviation, minimum and maximum values, where applicable) of clinically meaningful endpoints will be tabulated

Exclusion Criteria
  • Neurological symptom(s) due to vitamin B12 deficiency
  • Requires tracheotomy ventilation or noninvasive ventilation > 16 hours / day
  • Comorbidities such as Parkinson's disease, schizophrenia, renal failure, or any other severe complication that, in the Investigator's opinion, will compromise the safety of the patient or confound interpretation of the data collected in this study
  • Other neuromuscular disease
  • Inflammatory disorder of the blood vessels (inflammatory angiopathy, such as Buerger's disease)
  • Active infection
  • Chronic inflammatory disease (e.g., Crohn's disease, rheumatoid arthritis)
  • Positive HIV or HTLV at Screening

  • Subjects requiring > 81 mg daily of acetylsalicylic acid; subjects may be enrolled if willing/able to switch to ≤ 81 mg daily of acetylsalicylic acid or to another medication
  • Subjects requiring regular COX-2 inhibitor drug(s) or non-specific COX-1/COX-2 inhibiting drugs, or high dose steroids (excepting inhaled steroids); subjects may be enrolled if willing/able to undergo medication wash-out prior to the first dosing and to refrain from taking these drugs for the duration of the study
  • Have used an investigational drug within 30 days of Screening

GroupInterventionDescription
VM202VM202Total dose of 64 mg of VM202 It will be administered over the course of four visits: Day 0, Day 7, Day 14, and Day 21. As in all previous VM202 studies, final dose of VM202 for each target muscle group is divided and administered 2 weeks apart.
Primary Outcome Measures
NameTimeMethod
Number of Subjects With Serious and Non Serious Adverse EventsThroughout the nine month follow up

Adverse events (including serious adverse events, and adverse events leading to treatment discontinuation) throughout the 9 months follow-up. Descriptive statistics will be used to characterize safety parameters.

Secondary Outcome Measures
NameTimeMethod
Change in Mean Muscle Strength Medical Research Council (MRC) ScoresDay 0, Day 30, Day 60, Day 90, at 6 months and 9 months

The Medical Research Council (MRC) Scale is a validated instrument used in assessing muscle strength. It uses the numeral grades 0-5 to characterize muscle strength as follows: 0 - No contraction;1 - Flicker or trace contraction; 2 - Active movement, with gravity eliminated; 3 - Active movement against gravity; 4 - Active movement against gravity and resistance; 5 - Normal power The MRC scale was used to assess muscle strength in the muscle groups injected with Engensis.

Change From Baseline (Day 0) in Forced Vital Capacity (%)Day 30, Day 60, Day 90, at 6 months and 9 months

pulmonary function test that quantifies the volume of air that can forcibly be blown out after full inspiration. It correlates with survival in ALS

The Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R)Screening, on Day 0 before the treatment (injection), on Day 30, Day 60, Day 90, at 6 months and 9 months

The Amyotrophic Lateral Sclerosis Function Rating Scale includes twelve questions that ask the physician to rate his/her impression of the patient's level of functional impairment in performing one of twelve common tasks (e.g., climbing stairs). Each task is rated on a five-point scale from 0 = can't do, to 4 = normal ability. Individual item scores are summed to produce a reported score of between 0 = worst and 48 = best.
