The Cystic Fibrosis Foundation is investing up to $15 million in Recode Therapeutics to accelerate the development of novel gene-editing medicines for individuals with cystic fibrosis (CF) who lack effective treatment options. This investment aims to address the unmet needs of CF patients with specific mutations.
Shehnaaz Suliman, MD, CEO of Recode, expressed gratitude for the CF Foundation's support, emphasizing the potential of their gene correction approach to significantly advance research in collaboration with Intellia and develop a transformative CF treatment.
Targeting the Root Cause of CF
Cystic fibrosis is caused by mutations in the CFTR gene, which provides instructions for making the CFTR protein. The absence of functional CFTR leads to the production of thick, sticky mucus that accumulates in organs, causing most of the disease's symptoms. While CFTR modulators have revolutionized care for many CF patients by improving the functionality of the mutated CFTR protein, they are only effective for individuals with specific mutations.
Gene Editing Approach
Recode, in collaboration with Intellia Therapeutics, is pioneering a new treatment strategy that alters the genetic code in patients' cells to create a healthy version of the CFTR gene, enabling functional protein production. This approach bypasses the limitations of CFTR modulators, potentially benefiting patients ineligible for modulator therapy. The project combines Intellia's gene-editing technology with Recode's delivery technology to introduce gene-editing machinery into patient cells. The funding will support the development of up to three gene-correction programs, initially targeting CF mutations not adequately treated by existing therapies.
Expanding Therapeutic Options
This investment marks the second major contribution from the CF Foundation to Recode. Previously, the foundation invested up to $15 million to support the development of RCT2100, an experimental mRNA therapy currently in clinical testing. Unlike the gene-editing approach, RCT2100 is an inhaled therapy designed to deliver a healthy version of CFTR messenger RNA (mRNA) to lung cells. By delivering healthy CFTR mRNA, RCT2100 aims to enable the production of functional CFTR in lung cells, irrespective of the patient's underlying mutation.
RCT2100 is currently being evaluated in a two-part Phase 1 clinical trial (NCT06237335). The first part involves testing the therapy in healthy volunteers, while the second part is testing it in people with CF. Patient dosing has commenced, with ongoing recruitment in New Zealand and the Netherlands. Additional sites in the U.S., the U.K., and France are expected to enroll patients in the future.
