Cell-Based Therapy for White Matter Repair in Periventricular Leukomalacia

July 17, 2025 updated by: MGAM LLC

Phase 1 Study Evaluating the Safety and Preliminary Efficacy of a Novel Cell-Based and Small Molecule Combination Therapy for White Matter Injury in Patients With Periventricular Leukomalacia

The goal of this study is to explore a new treatment that may help repair brain damage in individuals with periventricular leukomalacia (PVL), a condition that affects white matter in the brain. Researchers are testing whether a combination of a novel cell therapy and specific molecular agents can support brain repair.

The main questions the study aims to answer are:

Can the treatment help regrow white matter and improve myelin repair? Does the treatment reduce scarring in the brain? Is the treatment safe and well-tolerated?

The study uses several components, including:

A specific type of neural progenitor cell to form the basis of the therapy. A small molecule compound to support cell function and survival. An agent designed to promote the repair of the myelin sheath. An enzyme intended to break down scar tissue in the brain. Researchers will study how these components work together to protect and repair the brain by influencing key pathways involved in damage and recovery.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Experimental: Investigational Combination Therapy
Participants will receive an investigational combination therapy. This therapy consists of a proprietary cell-based component administered with a cocktail of molecular and enzymatic agents. These agents are designed to support cell health, promote myelin repair, and reduce inhibitory factors in the damaged brain tissue. The overall goal of the intervention is to promote white matter regeneration in patients with periventricular leukomalacia by targeting key barriers that prevent natural repair.
Combination product: Investigational Combination Product
This investigational therapy combines a proprietary, human-derived cell-based component with a unique blend of small molecules and an enzyme. The components are designed to work synergistically to address the complex pathology of white matter injury. The therapy aims to provide a source for cellular regeneration, support the survival of existing cells, enhance the potential for myelin repair, and modify the inhibitory environment of glial scar tissue. This multi-pronged biological intervention is designed to promote neural regeneration and functional recovery in patients with PVL.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in White Matter Integrity
Time Frame: At baseline and 12 weeks post-intervention
Measured using fractional anisotropy (FA) values derived from diffusion tensor imaging (DTI) MRI to assess structural white matter characteristics in brain regions affected by periventricular leukomalacia (PVL).
At baseline and 12 weeks post-intervention

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Functional Motor Score
Time Frame: Baseline, 6 weeks, and 12 weeks post-intervention
Measured using the Gross Motor Function Measure-88 (GMFM-88). The scale ranges from 0 to 100; higher scores indicate better motor function.
Baseline, 6 weeks, and 12 weeks post-intervention
Change in Glial Scar Density
Time Frame: 12 weeks post-intervention
Quantified using established biomarkers for astrogliosis, such as glial fibrillary acidic protein (GFAP), from cerebrospinal fluid or via advanced imaging. This outcome is intended to measure the biological activity of the therapy's scar-reducing component.
12 weeks post-intervention
