Phase 1
Recruiting
Led By Alan Hand, MD
Research Sponsored by Motric Bio
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Weight ≥50 kg and BMI <33 kg/m2
Aged 18-45 years and in good physical health based on medical history, physical examination, vital signs, laboratory, ECG, Echocardiography, muscle strength, and spirometry test values
Must not have
Use of medications/products known to alter drug absorption, metabolism, or elimination processes within 30 days prior to dosing
Active neoplastic disease or history of any neoplastic disease within 5 years of screening
Timeline
Screening 3 weeks
Treatment Varies
Follow Up from baseline to day 18.

Summary

This trial tests a new drug, MTR-601, in healthy volunteers to see if it is safe. Researchers will measure how the drug behaves in the body and its effects on muscle strength.

Who is the study for?
Healthy non-smokers aged 18-45 with a BMI <33 kg/m2 can join this trial. They must not have used tobacco for 3 months, be in good health based on various medical tests, and agree to use contraception if applicable. People with cardiovascular diseases, positive drug/alcohol screens, recent surgeries that affect drug absorption or metabolism, or those who've been hospitalized recently cannot participate.
What is being tested?
The study is testing MTR-601's safety and how the body processes it under different conditions (with food or without). It will also look at how MTR-601 affects muscle strength and its accumulation in muscles through biopsies and other markers.
What are the potential side effects?
While specific side effects are not listed here, common ones may include reactions at the injection site, fatigue, headache, nausea. The trial aims to identify any potential side effects from single or multiple doses of MTR-601.

Pharmacodynamic of MTR-601-Forearm extension and flexion strength by dynamometry
Pharmacodynamic of MTR-601-Grip strength by dynamometry
+6 more
Other study objectives
Exploratory biomarkers of MTR-601 activity.

Other Research
The most common treatments for Cerebral Palsy (CP) target spasticity and include oral antispasticity medications like baclofen and benzodiazepines, which work by enhancing inhibitory neurotransmission to reduce muscle stiffness. Botulinum toxin injections block acetylcholine release at the neuromuscular junction, leading to muscle relaxation. Alcohol blocks and selective dorsal rhizotomy disrupt nerve signals to reduce spasticity. Intrathecal baclofen pumps deliver medication directly to the spinal fluid, providing targeted relief with fewer systemic side effects. Understanding the pharmacokinetics and pharmacodynamics of these treatments is crucial for optimizing their efficacy and safety, similar to the goals of the MTR-601 trial, which evaluates these parameters to ensure effective and tolerable treatment options for CP patients.
Functional and surgical treatments in patients with spinal muscular atrophy (SMA).
