Brief summary
The proposed study is an Open-Label, Single-Dose Study to Assess the Safety, and Pharmacodynamics (PD) signals of MRG-001 in Patients with Amyotrophic Lateral Sclerosis (ALS). MRG-001 will be administered subcutaneously 3 times per week for 2 weeks. This cycle will be repeated for 3 months. In total, patients are expected to receive 18 injections over the span of 3 months.

Inclusion criteria
* Able to provide written informed consent (either from patient or patient's legally acceptable representative and complying with study procedures, in the PI's opinion. * Male or female patients between 18-75 years. * Sporadic or familial ALS diagnosed as clinically possible, probable, lab-supported probable, or definite ALS defined by revised El Escorial criteria. * Time since onset of weakness due to ALS ≤ 48 months at the time of the Screening Visit * Vital Capacity ≥ 50% of predicted capacity for age, height, and sex at the time of the Screening Visit measured by Slow Vital Capacity (SVC), or Forced Vital Capacity (FVC). * Patients must either not take Riluzole or be on a stable dose of Riluzole for ≥ 30 days prior to the Master Protocol Screening Visit. Riluzole-naïve participants are permitted in the study. * Participants must either not take Edaravone or have completed at least one cycle of edaravone prior to the Master Protocol Screening Visit. Edaravone-naïve participants are permitted in the study. * Participants must either not take Relyvrio (AMX0035) or be on a stable dose of Relyvrio for ≥ 30 days prior to the Master Protocol Screening Visit. Relyvrio-naïve participants are permitted in the study. * Women of child-bearing potential (defined as females who are not surgically sterile or who are not over the age of 52 and amenorrhoeic for at least 12 months) must utilize appropriate birth control throughout the study duration. * Male patients must agree to use a medically acceptable method of contraception /birth control throughout the study duration.
Exclusion criteria
* Subjects who meet one or more of the following criteria will not be considered eligible to participate in the clinical study: * Participation in another interventional clinical trial (drug or device) within 30 days of Screening and at any time during the study. * Significant pre-existing organ dysfunction prior to randomization: * Lung: Receiving supplemental home oxygen therapy at baseline for pre-existing medical condition (other than COVID-19), as documented in medical record. * Heart: Pre-existing congestive heart failure defined as an ejection fraction \<20% as documented in the medical record. Clinically significant ventricular arrhythmias (ventricular tachycardia, ventricular fibrillation), unstable angina, myocardial infarction (past 3 months), heart and coronary vessel surgery (past 3 months), significant valvular heart disease, uncontrolled arterial hypertension with systolic blood pressure \>180 mm Hg and diastolic blood pressure \>110 mm Hg. * Renal: End-stage renal disease requiring renal replacement therapy or creatinine clearance \<50 mL/min. * Hematologic: Baseline platelet count \<30,000/mm3 or hemoglobin levels \<6.0 g/dL. * Neurological: Stage ≥3 hepatic encephalopathy by West Haven criteria. * History of splenectomy or splenomegaly (spleen weighing \> 750 g). * Active cancer or history of cancer, except for the following: basal cell carcinoma or successfully treated squamous cell carcinoma of the skin, cervical carcinoma in situ, prostatic carcinoma in situ, or other malignancies curatively treated and with no evidence of disease recurrence for at least 3 years. * Presence of unstable psychiatric disease, cognitive impairment, dementia or substance abuse that would impair ability of the participant to provide informed consent, in the SI's opinion. * Exposure at any time to any gene therapies under investigation for the treatment of ALS (off-label use or investigational) including tofersen (Qalsody). * History of splenectomy or splenomegaly (spleen weighing \>750 g). * Co-infection with human immunodeficiency virus (HIV). * History of organ or bone marrow transplantation, other than a corneal transplant. or recent (within 3 months) chronic use of immunosuppressive drugs (tacrolimus, mycofenolate mofetil, cyclosporine, rapamycine, hydrochloroquine, azathiopurine, methotrexate), e.g., biologicals, JAK1/2 inhibitors, interferons, interleukins or (prednisone or related corticosteroids are allowed). * Hypersensitivity to either of the components of MRG-001. * If female, known pregnancy, or has a positive serum pregnancy test, or lactating/breastfeeding. * Underlying diseases that, in the opinion of the site investigator, might be complicated or exacerbated by proposed treatments or might confound assessment of study drug.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Assessment of Treatment-Emergent Adverse Events | 3 Months | Assess the safety and tolerability of MRG-001 in patients with Amyotrophic Lateral Sclerosis (ALS) as determined by the absence of serious adverse events (SAE) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Stem Cell Mobilization | 24 hours | The absolute change in numbers of CD34+ hematopoetic stem cells as measured by flow cytometry |
| Regulatory T-cell Mobilization | 24 hours | The absolute change in numbers of FOXP3+ regulatory T-cells as measured by flow cytometry |
| Change in Disease Progression | 3 Months | Change in disease severity over time as measured by the ALS Functional Rating Scale-Revised (ALSFRS-R) at Baseline, 1, 2 and 3 months. Each type of function is scored from 4 (normal) to 0 (no ability), with a maximum total score of 48 and a minimum total score of 0. Patients with higher scores have more physical function. Positive data means the reversal of ALS disease, negative data means disease progression, zero means stabilization of disease. |
