ClinConnect Summary

This clinical trial is looking at a new treatment called MRG-001 for patients with Amyotrophic Lateral Sclerosis (ALS), a serious condition that affects nerve cells in the brain and spinal cord. The study aims to understand how safe MRG-001 is and how it works in the body. Participants will receive MRG-001 as an injection under the skin three times a week for two weeks, repeating this cycle for a total of three months, which means they will receive a total of 18 injections during the trial.

To join the trial, participants need to be between 18 and 75 years old and have a confirmed diagnosis of ALS. They should be able to provide consent, either themselves or through a legal representative, and must meet certain health criteria, such as having good lung function. It's important to note that women who could become pregnant must use birth control during the study. The trial is not yet recruiting participants, so if you or someone you know is interested, it's best to keep an eye out for when it starts.

• • 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.
