Description of intervention(s) / exposure
This study is a First in Human, open label, SAD and MAD study to determine the safety and PK characteristics of mEphA4-Fc in HVs and patients with ALS. Measurements of clinical and lung function endpoints associated with ALS will also be assessed.
There will be two parts:
Part 1 (SAD) of the study will be conducted in five cohorts of 4 subjects each.
The MAD part of the study will be conducted in two cohorts of 4 ALS patients each.

Investigational Product (IP): mEphA4-Fc
Presentation: Liquid in a Glass vial: 10 mL at 10 mg/mL
Mode of administration: Intravenous (IV) infusion

mEphA4-Fc will be administered as an IV infusion in a 0.9% sodium chloride solution (normal saline). Each infusion of mEphA4-Fc administration should be completed within 75-90 minutes.

Part 1 (SAD) in Healthy Volunteers: Each cohort will be comprised of 4 HVs each to receive mEphA4-Fc. mEphA4-Fc will be given in sequential, escalating doses;
Incremental doses starting from a dose selected according to the NOAEL strategy for FIH studies will be administered and the planned increments will not exceed 3 fold. The minimum and maximum doses for each cohort are limited by body weight.
The actual dose level for a cohort will be ultimately decided by the Safety Review Committee based on a review of data from the proceeding cohort/s.

Part 2 (MAD) in ALS Patients: The first multiple dose cohort may be initiated prior to the completion of the fifth SAD cohort and after completion of the fourth SAD cohort. The multiple ascending dose will be comprised of two cohorts of 4 ALS patients each to receive mEphA4-Fc.
The frequency of administration, dose increments and number of cohorts will be reviewed based on review of all data by the Safety Review Committee.

Each cohort will be comprised of 4 subjects each to receive 4 doses of mEphA4-Fc, over 28 days.
The proposed time duration between each dose will be 7 days, but will be reviewed by the Safety Review Committee.

To monitor adherence to the intervention for all SAD/MAD cohorts: Clinical trial management system, laboratory tests, and pharmacy records.

Part 1: 1mg/kg, 3mg/kg, 10mg/kg, 20 mg/kg, 30 mg/kg
Part 2: 15mg/kg, 30mg/kg
Part 3(Extended Access Study) in ALS Patients. Total of 8 ALS patients in 2 cohorts. The study patients will receive 5 cycles of 4 weekly infusions.
Part 3 will involve 4 infusions of 15 / 20 or 30 mg/kg weekly, in a 4-week cycle, for up to 6 months. Each dose of mEphA4-Fc will be given as an IV infusion over 90 to 120 minutes. The 4 infusions will take place 7 days apart, at Day 1, 8,15, 22, or until intolerable toxicity, progression of disease, or withdrawal of consent. Therefore, all subjects will have been dosed for 6 cycles for up to 6 months when they complete the Phase 1b study.

All MAD subjects who want to continue receiving mEphA4-Fc treatment will be directly moved to Part 3. So, the cohorts in Part 2 will be unique cohorts in Part 3. The first dose of Part 3 would be 7 days post the last dose of the MAD part 2.

Part 3 addition was anticipated prior to enrolment commencement for Part 2, but has been implemented post enrolment given the same subjects are involved in Parts 2 and 3.
