Summary

This is an open-label, single-arm, multicenter Phase 1/2 study evaluating the safety and efficacy of gene therapy by transplantation of Prime Edited autologous CD34+ stem cells modified ex vivo (PM359) in participants with autosomal recessive Chronic Granulomatous Disease (CGD) caused by mutations in the NCF1 (Neutrophil Cytosolic Factor 1) gene.

Who is the study for?
This trial is for individuals with autosomal recessive Chronic Granulomatous Disease (CGD) due to NCF1 gene mutations. Specific eligibility criteria are not provided, but typically include factors like age, disease severity, and overall health status.
What is being tested?
The study tests a new gene therapy called PM359. It involves editing the genes of a patient's own stem cells and then transplanting them back into the body to treat CGD.
What are the potential side effects?
Potential side effects are not detailed here, but gene therapy can sometimes cause immune reactions, bleeding or infection from the stem cell collection/transplantation process, and possible off-target genetic effects.

Study Objectives

Study objectives can provide a clearer picture of what you can expect from a treatment.
Primary study objectives
Percentage of participants with sustained reconstitution of NADPH oxidase activity in neutrophils
Safety of administration of PM359, as quantified by frequency of adverse events (AEs) after drug product infusion
Secondary study objectives
Durability of multi-lineage hematopoietic cell reconstitution
Frequency of all drug product-related AEs, ≥ Grade 3 AEs, and serious adverse events (SAEs)
Frequency of any new or worsening moderate or greater CGD associated infection requiring anti-microbial therapy with confirmed microbiology demonstrating bacterial or fungal origin consistent with CGD-related pathology, as compared to baseline

Trial Design

1Treatment groups
Experimental Treatment
Group I: PM359Experimental Treatment1 Intervention
PM359 is an autologous CD34+ hematopoietic stem cell (HSC) suspension that is Prime Edited at the NCF1 locus resulting in expression of the p47phox protein.
