Clinical Trial Summary

A Phase 2a Open-Label Preliminary Safety, Efficacy, and Biomarker Study of WP-0512 in Patients with Amyotrophic Lateral Sclerosis (ALS)

Clinical Trial Description

The study population will consist of subjects with a diagnosis of probable laboratory-supported, probable, or definite ALS, as defined by El Escorial Revised ALS diagnostic criteria; with ALS symptom onset within 48 months; and with percent predicted SVC ≥ 50% at Screening 1. Subjects must also have an average rate of decline in ALSFRS-R at Screening 1 of 0.5 to 3.0 points/month, with rate of decline calculated using historical data (either prior ALSFRS-R score or date of ALS symptom onset). This study will be composed of a Primary Phase, with 24 weeks of open-label treatment, and an optional 12-month Extension Phase. After consent, participants will undergo two screening evaluations, which will occur over the course of the 8 weeks prior to dosing with study drug. At Screening 1/Visit 1 (8 weeks before start of dosing), ALS assessments of ALSFRS-R/SVC/muscle dynamometry (HHD and hand grip) will be performed, as will safety assessments. Subjects who meet the pertinent inclusion/exclusion criteria will return for a second screening visit (Screening 2/Visit 2) approximately 4 weeks later, and ALS and safety assessment will again be conducted. Subjects who meet the pertinent Screening 2 study entry criteria will be enrolled into the study. On Visit 3/Day 1, evaluations will be performed and dosing with study drug will begin. Dosing will be initiated at 180 mg/day; after at least 10 subjects have been enrolled and safely treated at 180 mg/day for 4 weeks, subsequent subjects may be enrolled at up to 240 mg/day. Participants will have an in-person or telephone visit at Week 1 (Visit 4) to assess for safety and drug compliance. Additional visits will occur at Weeks 4 (Visit 5), 8 (Visit 6), 12 (Visit 7), 18 (Visit 8) and 24 (Visit 9), during which ALS assessments of ALSFRS-R/SVC/HHD will be performed. For subjects who do not enter the Extension Phase, a final post-treatment follow-up visit (Visit 10) will be conducted at Week 25 (or 7±2 days after early termination). For subjects who consent to continue in the Extension Phase, visits will occur every three months, during which ALS assessments will be done. Blood biomarker collection will occur between enrollment and commencement of treatment, and at Week 12 (Visit 7) and Week 24 (Visit 9); during the extension phase it will occur on Visit 12 and Visit 14. CSF biomarker collection will occur between enrollment and commencement of treatment, and at Week 24 (Visit 9). Laboratory safety assessments and adverse events will be collected at each study visit. Subjects/caregivers will be asked to maintain a log of adverse events, study drug compliance, and medication changes, which will be reviewed at each visit. ;
