Molecular Biology Tools to Unlock the Full Potential of Your Gene Therapy Products
Biodistribution, transgene expression, and vector shedding are critical components of a gene therapy molecule’s development, providing crucial data for IND-enabling preclinical studies and safety evaluation during clinical development.
Gene therapy carries potential risks, including unintended effects caused by the gene therapy vector. Biodistribution studies are critical for determining the distribution and persistence of the gene therapy vector in target and non-target tissues and are generally combined with transgene expression assessments to aid interpreting any observed adverse effects from the toxicology studies.
A key aspect of clinical safety involves understanding the potential for vector shedding of the administered gene therapy. Evaluation of biofluids informs understanding of personal and environmental risks and is also a recommended part of preclinical development. Inadequate safety data could lead to regulatory approval challenges and delay time to the clinic.

Biodistribution & Transgene Expression
Gene therapies (for example, adeno-associated viral (AAV) and adenoviral (AdV) vectors) are targeted therapies administered to patients to treat a range of monogenic diseases. Safety and efficacy rely on the delivery of the therapeutic to the target tissue.
Uptake by non-target tissues is common, risking patient safety and therapeutic effectiveness. Biodistribution studies are conducted during preclinical development to evaluate how gene therapies are taken up and retained in vivo. Understanding the biodistribution of a product in preclinical models is essential for assessing the risk during preclinical gene therapy development.
Viral vectors used for in vivo gene delivery (e.g., AAV) can be shed from the patient via biofluids following administration, and persistent levels can indicate that unwanted replication of the vector is occurring.
Therefore, vector shedding data provides critical information during the clinical development of these types of products.
