About Cystic Fibrosis Lung Disease

Cystic fibrosis (CF) is an inherited progressive disease caused by mutations in the CFTR gene. It affects the lungs, pancreas and other organs. According to the Cystic Fibrosis Foundation, nearly 40,000 people in the United States and more than 105,000 people worldwide are living with CF, with approximately 1,000 new cases of CF diagnosed in the United States each year. Lung disease is the leading cause of morbidity and mortality in people with CF. CF causes impaired lung function, inflammation and bronchiectasis and is commonly associated with persistent lung infections and repeated exacerbations due to the inability to clear thickened mucus from the lungs. People with CF require lifelong treatment with multiple daily medications. The complications of the disease result in progressive loss of lung function, increasing need for IV antibiotics and hospitalizations, and ultimately lead to end-stage respiratory failure.

About 4D-710

4D-710 is comprised of our targeted and evolved next generation AAV vector, A101, and a codon-optimized CFTR∆R transgene. 4D-710 has the potential to treat a broad range of people with CF, independent of the specific CFTR mutation, and is designed for aerosol delivery to achieve targeted CFTR expression within lung airway epithelial cells. 4D-710 is being initially developed for the approximately 15% of people with CF whose disease is not amenable to existing CFTR modulator medicines (based on variant-eligibility and/or drug intolerance). In people with CFTR variants that are amenable to modulator medicines, the improvement in lung function is variable and often incomplete. We therefore expect to potentially develop 4D-710 for use in this broader population, either as a single agent and/or in combination with CFTR modulator medicines. 4D-710 has received the Rare Pediatric Disease Designation and Orphan Drug Designation from the U.S. Food and Drug Administration (FDA).
