Menlo Park, Calif. – March 25, 2025 – ReCode Therapeutics, a clinical-stage genetic medicines company using tissue-specific delivery to power the next wave of mRNA and gene correction therapeutics, today announced that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation for RCT2100, a novel, investigational mRNA therapy being developed to treat cystic fibrosis (CF).
CF is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Although recent advancements in CFTR modulator therapies have improved outcomes for many people with CF, those with certain mutations remain underserved because these mutations prevent the production of functional CFTR protein, making current treatments ineffective.
RCT2100 was formulated leveraging ReCode’s proprietary Selective Organ Targeting (SORT) lipid nanoparticle (LNP) platform and is designed to deliver CFTR mRNA directly to target cells in the lungs, instructing them to produce a functional version of the CFTR protein that is missing in some individuals with CF. By providing this CFTR mRNA, the therapy aims to address the root cause of CF, potentially restoring CFTR protein function in the lungs.
“While there have been tremendous advancements in the development of novel CF therapies in the past two decades, we are focused on the subset of CF patients who are not eligible for current treatments and who have been waiting for a treatment,” said Shehnaaz Suliman, M.D., MBA, M.Phil., chief executive officer of ReCode Therapeutics. “We are currently enrolling patients in a Phase 1b study evaluating RCT2100 in people with CF who do not respond to or are intolerant of current modulator therapies. We are grateful to the cystic fibrosis community and physicians for the continued support of the RCT2100 clinical program.”
A Phase 1b study evaluating RCT2100 is currently enrolling individuals with CF in the United States, United Kingdom, France, and the Netherlands. For more information, please visit CF-Clinical-Studies.com.
About Cystic Fibrosis
Cystic fibrosis (CF) is a progressive genetic disease that causes persistent lung infections and respiratory failure. CF is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. An estimated 105,000 people have been diagnosed with CF across 94 countries, according to the Cystic Fibrosis Foundation. The absence or dysfunction of the CFTR protein results in a defect in airway hydration, which leads to excessive mucus buildup in the lungs and other organs. It also results in a mucociliary clearance defect, recurrent infections, inflammation, respiratory failure, and other complications. Despite advancements in CFTR modulator treatments, approximately 10% of people in the CF community have genetic mutations that do not enable them to benefit from these life-changing therapeutics.
About ReCode Therapeutics
ReCode Therapeutics is a clinical-stage genetic medicines company using precision delivery to power the next wave of mRNA and gene correction therapeutics. ReCode’s proprietary Selective Organ Targeting (SORT) lipid nanoparticle (LNP) platform enables highly precise and targeted delivery of genetic medicines directly to the organs, tissues, and cells implicated in disease, enabling improved efficacy and potency.
ReCode’s lead programs include RCT2100 for the treatment of the 10% of people with cystic fibrosis who have genetic mutations in the CFTR gene that do not respond to currently approved CFTR modulators or those that are intolerant of approved CFTR modulators and RCT1100 for the treatment of primary ciliary dyskinesia caused by pathogenic mutations in the DNAI1 gene. RCT1100 and RCT2100 are inhaled disease-modifying mRNA-based therapies formulated with the SORT LNP delivery platform. ReCode is expanding its pipeline to develop potential therapies for other rare and common genetic diseases, including central nervous system, liver, and infectious disease indications.
