Novel gene therapies show promise for sickle cell cure


 

In this technique, the Cas9 protein makes a cut and repairs an individual’s genomic DNA by inserting a strand of corrected donor DNA. The novel technology would allow for targeted genome editing that is specific to the SCD patient.

Currently, this experimental therapy is being investigated in preclinical studies. Dr. Walters said that he and his colleagues hope to begin enrolling patients in clinical trials within the next 1-2 years.

But while some gene therapies have been approved in other disorders, such as spinal muscle atrophy, a limiting factor to widespread availability is cost. Despite promising initial results in SCD, the affordability of future gene therapies will be a key factor to universal access, Dr. Walters said.

The Cure Sickle Cell Initiative

Traci Mondoro, PhD, chief of the Translational Blood Science and Resources Branch at NHLBI, explained that the NHLBI has funded a large proportion of the research that has formed the basis of several genetically based clinical studies.

One of the primary goals of the Cure Sickle Cell Initiative is to bridge the gap between new research and the SCD community. Their aim is to improve access for patients to participate in genetically based studies to advance cures.

The comprehensive approach is intended to fill in existing gaps by funding breakthrough research in both academic and private settings.

By establishing partnerships with key stakeholders, institutions, and patient groups, Dr. Mondoro said they hope to increase patient participation in clinical trials involving curative therapies. In the future, they also intend to establish a large body of evidence to provide adequate safety data to study these therapies in pediatric populations.

Dr. Walters and Dr. Mondoro did not provide information on financial disclosures.
