A Study of IPL344 in the Treatment of ALS Patients

Phase 1

Suspended

• Conditions: Amyotrophic Lateral Sclerosis
• Interventions: Drug: IPL344

• Registration Number: NCT03652805
• Lead Sponsor: Immunity Pharma Ltd.

Brief Summary

This is a prospective, open-label, phase 1/2a study, dose escalation, to evaluate tolerability, safety, and PK of I.V. administered IPL344 in participants with Amyotrophic Lateral Sclerosis (ALS).

Detailed Description

The study is designed to determine the tolerability, safety and PK of IPL344 administered I.V. once a day for 28 days and to identify the maximum tolerated dose.

All patients enrolled will have a documented history of ALS disease prior to study enrollment.

Treatment will start with 1.7mg/kg with dose escalation by 0.5 mg/kg every 3-4 days and will increase to the maximum dose of 3.2mg/kg. Day 1 to Day 28 patients will be on active treatment.

After completion of 28 treatment days, participants who will choose to continue treatment (at the investigator's discretion), will be enrolled in a follow-up study. Participants that discontinue treatment after Day 28 will be followed up by a nurse phone call and return to the clinic for a final visit on Day 56 from the first dose.
