Boehringer Ingelheim Launches First-in-Class Inhaled Gene Therapy Trial for Cystic Fibrosis
• Boehringer Ingelheim initiates LENTICLAIR 1 Phase I/II trial evaluating BI 3720931, a novel inhaled gene therapy targeting cystic fibrosis using Oxford Biomedica's lentiviral vector technology.
• The innovative therapy aims to address the 10-15% of cystic fibrosis patients who cannot benefit from current CFTR modulators due to mutation type or intolerance.
• Oxford Biomedica's proprietary lentiviral vector manufacturing expertise will support the development of this groundbreaking treatment that delivers functional CFTR genes to airway epithelial cells.
Boehringer Ingelheim has launched a groundbreaking clinical trial for a first-in-class inhaled gene therapy targeting cystic fibrosis (CF), marking a significant advancement in genetic medicine. The LENTICLAIR 1 Phase I/II study will evaluate BI 3720931, developed using Oxford Biomedica's proprietary lentiviral vector manufacturing technology.
The novel therapeutic approach aims to address the fundamental genetic cause of CF by delivering functional copies of the CFTR gene directly to airway epithelial cells. This strategy represents a potential breakthrough for patients who currently have limited treatment options.
Cystic fibrosis affects more than 100,000 people worldwide, caused by mutations in the CFTR gene that lead to severe respiratory and digestive complications. While CFTR modulators have revolutionized treatment for many patients, approximately 10-15% of individuals with CF cannot benefit from these therapies due to their specific mutation types or intolerance to existing treatments.
The collaboration leverages Oxford Biomedica's three decades of expertise in viral vector development and manufacturing. Their proprietary lentiviral vector technology has been specifically optimized for this innovative inhaled delivery approach, potentially offering a more targeted and efficient method of gene therapy administration.
BI 3720931 employs a novel mechanism of action, using lentiviral vectors to transport and integrate functional CFTR genes into the DNA of airway epithelial cells. This approach differs from conventional CFTR modulators by addressing the genetic root cause of the disease rather than merely modifying protein function.
The LENTICLAIR 1 trial represents a significant milestone in CF treatment development, combining advanced gene therapy technology with an inhaled delivery system designed to maximize therapeutic efficacy while potentially improving treatment accessibility for patients.
