Gene therapy is a revolutionary medical approach designed to treat or prevent disease by introducing normal or modified genetic material into a patient's body. Formulation studies in gene therapy is a multi-step process aimed at designing and optimizing therapeutics that can safely and effectively deliver therapeutic genes to target cells. The design and studies of stable formulations play an important role in gene therapy.

Our expert team has many years of service experience in formulation studies, and we can design the best formulation solution according to the customer's project needs to help your project research. Our gene therapy formulation studies services include but are not limited to the following.
This process deals with the selection and optimization of viral vectors such as adeno-associated viruses, lentiviruses, adenoviruses, and other vectors. The selection of non-viral vectors, such as liposomes and polymeric nanoparticles, can be targeted according to the experimental objectives.
When making stability selections for gene therapy formulations, we focus on physical stability, i.e., ensuring that gene therapy formulations are stable under varying conditions of temperature, humidity, and light. As well as chemical stability, i.e. preventing degradation of active ingredients or adverse chemical reactions. Colleague biostability studies are also a very important aspect, where we need to ensure the protection of the genetic material from degradation enzymes in vivo.
We need to select the appropriate route of administration (e.g., intravenous, intramuscular, local injection, etc.) to ensure delivery efficiency and targeting. At the same time, we also need to determine the dose of the drug under different routes of administration, i.e., the concentration and volume need to be strictly controlled.
We need to determine the buffer solution to keep the pH of the solution stable. Stabilizers also need to be identified to prevent degradation of the formulation during storage and delivery. In addition, protective agents and surfactants are also important, such as coenzymes and PEG (polyethylene glycol), which help to improve the stability and biocompatibility of the genetic formulation.
During formulation studies, we need to perform purity testing, sterility testing to ensure that the formulation is free from microbial contamination, endotoxin testing, and many other tests.
Efficacy is a key attribute for product characterization, and we need to perform efficacy determination using matrix methods, including direct and indirect determination.

Platforms & Technologies | Content Description |
---|---|
Encapsulation and protection technology platforms | We utilize PEGylation for masking immunogenicity and extending half-life in vivo. We also utilize a variety of nanocarriers, such as gold nanoparticles, silica nanoparticles, exosomes, etc., for the protection and efficient transportation of gene materials. |
Gene delivery technology platforms | We have established electroporation technology, in which the cell membrane is briefly opened by electrical stimulation to allow the entry of gene materials into the cell. There is also ultrasound technology, which introduces genetic material into cells by utilizing sound waves to permeate the cell membrane. |
Cell-specific delivery technologies | Enhances the efficiency of targeted delivery by engaging ligands for specific cellular receptors on the surface of the delivery system. As well as utilized to direct vectors to specific cells or tissues to improve therapeutic targeting and efficiency. |

This study comprehensively analyzes the upstream, downstream, and formulation unit operational challenges encountered during AAV vector manufacturing. It discusses how to maintain desired product quality attributes throughout the product shelf life by understanding degradation mechanisms and formulation strategies. Various mechanisms of physical and chemical instability that may be encountered in viral vectors during production and shelf life due to various stress conditions such as heat, shear, freeze-thaw, and light are highlighted. The effects of buffers, pH, excipients, and impurities on the stability of viral vectors are also discussed.
