Advancements in pulmonary medicine are focusing on delivering gene therapy precisely to bronchiolar and alveolar tissues; new methods using nasal spray are being investigated for their potential to improve targeting efficiency in respiratory disease treatment.
Researchers have demonstrated that gene therapy administered via nasal spray can achieve targeted delivery to pulmonary tissues, highlighting its precision in reaching specific areas of the lungs. Traditional systemic or intratracheal methods often fail to reach deeper lung regions effectively and carry risks of "off-target transduction," where non-target cells are affected, and "systemic side effects," which are unintended effects on the body as a whole. This nasal spray drug delivery innovation capitalizes on direct mucosal access to maximize local transduction, highlighting the rise in innovative pulmonary therapeutics.
Central to this novel airway targeting in gene therapy is the incorporation of adeno-associated virus (AAV) with the CPP.16 technology, which enhances vector delivery within the nasal formulation. AAV.CPP.16 vectors are designed to navigate the mucus barrier with enhanced tropism for pulmonary epithelial cells, which may increase delivery specificity and boost therapeutic efficacy compared to conventional viral capsids.
For respiratory therapists and pulmonologists, translating these nasal administration approaches for lung diseases into clinical protocols offers familiar parallels to inhalation therapies while extending capabilities to genetic payloads. Directly targeting lung tissues may reduce systemic exposure, minimizing off-target effects and improving safety profiles compared to systemic infusion.
As these gene therapy nasal spray platforms advance toward clinical evaluation, practitioners should anticipate adaptation of inhalation devices and training on aerosolized genetic therapeutics. Ongoing research must address durability of expression, immunogenicity, and performance across diverse patient populations to fully realize the potential of these new methods in respiratory disease treatment.
