The swift progression of gene therapy has garnered significant international interest, particularly for its therapeutic potential across a spectrum of medical conditions. Yet, the intricacies of gene manipulation present certain challenges, including the possibility of unforeseen risks. To address these, meticulous biosafety evaluations are indispensable, ensuring that the gene therapies developed are both secure and potent.
CD Formulation boasts a rich history in the realm of gene therapy research, having honed our skills over many years. We pride ourselves on offering in-depth biosafety testing services that are integral to the lifecycle of gene therapy product development. Our commitment to excellence in this domain guarantees that the therapies we help bring to market are not only safe but also highly effective for their intended use.
Biosafety testing covers many aspects of gene therapy product development, including but not limited to the following.
This process includes insertional mutagenesis risk assessment, which entails testing whether the gene vector causes genomic insertional mutagenesis that may lead to tumorigenicity or cellular dysfunction. It also needs yah replicative capacity assay for viral vectors, which is used to confirm that viral vectors are replication-competent to avoid unintended viral spread.
The main need is to assess whether the gene therapy product will trigger a strong reaction of the immune system, such as the production of antibodies against the vector or the transgenic product.
Detect the persistence of gene therapy products in vivo, including the persistence existence and degradation of gene expression and vectors.
Evaluate whether the genes introduced by the treatment correctly express the corresponding proteins through western blot, ELISA, and other methods.
Evaluate the integration of therapeutic genes at random or specific sites in the genome using e.g. advanced sequencing technologies.
Ensure products are free of exogenous viral contamination, including the detection of exogenous DNA and RNA by PCR.
We confirm the consistency of the purity of each component of the product through methods such as high-performance liquid chromatography (HPLC) and capillary electrophoresis. It is also necessary to ensure consistency in activity and safety from batch to batch.

The article discusses the modified vaccinia virus Ankara (MVA), originally developed as a smallpox vaccine, which has been extensively tested for use in vaccination and gene therapy since the 1990s. While MVA is known for its safety, the article emphasizes the importance of considering biosafety when assessing recombinant MVA (rMVA) for clinical trials. It outlines the key factors to be evaluated, including the characteristics of rMVA, the nature of the inserted foreign genes, and the potential for reversion, recombination, and spread. The paper also covers strategies to mitigate the identified risks.
