Unveiling the End Stages: The Last Mile
In a groundbreaking development, researchers are working on mRNA-based therapies to treat severe cases of cystic fibrosis (CF) that cannot be managed by current CFTR modulator therapies.
The scientist at the forefront of this research is Michael Kormann, who is developing a technique to modify RNA and reverse nonsense codons to produce full-length proteins. This could be a significant breakthrough for the 5-10% of CF patients whose rare genetic mutations render them unresponsive to the currently available CFTR modulator therapies.
The importance of these advancements in transitional medicine and day-to-day management cannot be overstated. Before the approval of CFTR modulator therapies in 2012, the life expectancy for CF patients was six months, a stark contrast to the many CF patients now living well into middle age.
The development of mRNA-based therapies for CF is not a sudden leap. It is the culmination of years of research and investment. The CF Foundation, in particular, has been a driving force behind these advancements. Their support, which has been sustained since 2015 for pediatric patients, has led to significant improvements in the treatment of CF.
Gabel and Voter, two researchers who have received this support, are conducting a study monitoring the long-term effects of CFTR therapies. The study, which began enrolling patients in December 2019, is a testament to the Foundation's commitment to understanding the full impact of these therapies on CF patients.
The focus on mRNA technology for treating CF is not without precedent. Lynne Maquat, a medical center professor, formulated theories over time that have led researchers to this point. Her 1981 breakthrough manuscript, "Unstable beta-globin mRNA in mRNA-deficient beta0 thalassemia," published in Cell, was the first to reveal the role of nonsense-mediated mRNA decay (NMD) in human cells.
However, despite the advancements in CF treatment, CF patients still face challenges as they grow older. Maintaining routine care is critical, and Scofield's medical center's Complex Care Center includes dedicated staff to address all forms of complex illnesses. The center's adult CF population has grown significantly, with the adult program now bigger than the pediatric one.
Yu's lab, another research hub in this field, is also focusing on using mRNA technology to treat severe CF cases. Their work could offer hope for a cure for CF patients with rare genetic mutations, much like how mRNA-based treatments have shown success in fighting COVID-19.
The potential of these therapies is exciting, and the findings from Yu's lab will be presented at a research conference in San Antonio in the Fall. The progress made in the treatment of CF is a testament to the power of scientific research and the dedication of researchers like Kormann, Gabel, Voter, and Yu. Their work offers a glimmer of hope for those affected by this debilitating disease.
