Partnership Accelerates Introduction of First Individualized mRNA-CRISPR Treatment
In a groundbreaking development, a collaborative effort between academic institutions, industry, and regulatory bodies has resulted in the creation of the world's first personalized mRNA-based CRISPR therapy. This revolutionary treatment was administered to baby KJ Muldoon, who was born with a rare single-gene mutation affecting his metabolism.
The accelerated timeline for developing this gene-editing product was an impressive six months, compared to the standard couple of years. This rapid development was made possible through a compassionate use framework, which fast-tracked the therapy for approval, adhering to FDA guidelines written with larger trials in mind. Despite the lack of commercialization intention from well-motivated academics, the drug was expedited to help KJ Muldoon.
Max Sellman, senior product manager for gene editing at Aldevron, provided insights into the manufacturing process at the BioProcess International (BPI) Conference in Boston. Aldevron, along with partner company Acuitas, played a crucial role in this collaboration. Acuitas supplied a clinically validated lipid nanoparticle (LNP) formulation, while Aldevron manufactured an mRNA-encoded base editor.
IDT, Aldevron's sister company, also contributed to the production of mRNA therapies by designing a custom guide RNA and offering off-target safety services. The collaboration aimed to demonstrate the modular nature of CRISPR drug development, which allows for rapid repurposing to treat multiple single-gene disorders.
One of the issues with urea cycle disorders, such as KJ's condition, is the lack of the CPS1 enzyme, which is needed to remove ammonia from the body. The collaborators' approach was designed to address this issue and provide a safe, high-quality, and efficient treatment.
The team at Children's Hospital of Philadelphia (CHOP) encountered KJ Muldoon and administered the treatment. The collaboration between these various entities worked closely with the FDA to streamline regulatory development for a single patient.
This development marks a significant step forward in the encyclopedic approach to developing CRISPR-mediated drugs for treating rare individual case-based diseases. The organization that has contributed to this approach is the Experimental and Clinical Research Center in Berlin, led by Simone Spuler, who works with CRISPR/Cas9 technology to develop targeted therapies such as for muscular dystrophy.
Aldevron aims to continue working with the industry to codify their approach for knocking down rare genetic diseases using gene editing. Delays in the development of gene-editing products can hinder their effectiveness in treating patients with conditions like urea cycle disorders. By streamlining the process and demonstrating the modular nature of CRISPR drug development, this collaboration has paved the way for faster and more efficient treatments in the future.
KJ Muldoon's story was made public in May, highlighting the potential of personalized medicine and the power of collaboration in the field of gene editing. The world eagerly awaits further developments in this promising area of research.
