In stability testing of gene therapy formulations, forced degradation testing, a key technique, is used to provide information on early degradation pathways and product breakdown by studying accelerated product degradation by exposing the formulation to extreme storage conditions. These studies are particularly applicable in the early gene therapy formulation development phase and help assess the potential risk of the formulation under normal storage conditions.
CD Formulation provides effective technical support and comprehensive assay solutions for forced degradation testing of gene therapy formulations. We rely on our advanced technology platform and professional technical team to provide high-quality and reliable forced degradation testing technology solutions to help researchers advance their gene therapy formulation development studies.
Forced degradation studies can provide important data for understanding the degradation pathways of formulations, identifying degradation products and potential chemical or physical changes. These studies can help developers better optimize formulations, select appropriate excipients, and determine suitable storage conditions to maximize control over the stability and safety of gene therapy formulations.
Forced degradation testing of gene therapy formulations is a test method that causes a certain degree of degradation of a gene therapy formulation by artificially setting up more intense conditions, such as high temperature, acid, alkali, oxidation, light, or high humidity. Our forced degradation assay services are designed to provide a comprehensive analysis of the degradation behavior of gene therapy formulations in the following areas.
We rapidly assess the degradation behavior of gene therapy products by simulating extreme conditions of temperature, light and humidity.
With the help of advanced analytical techniques, we trace the decomposition path of gene therapy formulations under extreme conditions in detail, which is used to reveal potential chemical modifications and physical changes.
In degradation product identification, we use analytical methods such as mass spectrometry and HPLC to identify key degradation products generated during the degradation process, providing data to support the optimization of gene therapy formulation development and storage conditions.
Finally, based on the results of the degradation study, we can provide customers with professional formulation improvement suggestions to ensure the long-term stability of the product by optimizing the gene therapy formulation.
Platforms & Technologies | Content Description |
---|---|
Temperature stress testing | To hasten drug deterioration, this test is conducted at higher temperatures. As an illustration, testing might be done at a temperature that is 10°C greater than the accelerated test. |
Humidity stress test | The sensitivity of a gene therapy formulation to humidity is assessed by increasing the relative humidity. |
Oxidizing stress test | The oxidative stability of a drug is assessed by using an oxidizing agent such as hydrogen peroxide. During oxidative stress testing, the type and concentration of the oxidizing agent can be determined by the nature of the target assay formulation itself. |
Photolytic stress test | The sensitivity of a gene therapy formulation to light is assessed by exposure to light conditions, particularly UV light. Test conditions should include specific requirements for total illumination and near-UV energy. |
Acid-base hydrolysis stress test | Conducted in acidic or alkaline solutions of different pH values to assess the stability of gene therapy formulations under different pH conditions. |
Forced degradation test | High-performance liquid chromatography (HPLC) is our recommended assay for forced degradation testing due to its accuracy, sensitivity, and strong compatibility with organic and water-based solvents. |

This paper reviews methods for forced degradation, or stress testing, of therapeutic proteins, emphasizing their importance in the development process. These studies aid in candidate selection, molecule characterization, formulation, assay development, and comparability studies. It covers various stress methods, including exposure to high temperatures, freeze-thaw cycles, mechanical stress, oxidation, and light, along with the materials and devices used in clinical settings. While regulatory guidelines define stability-testing requirements, standardized procedures for forced degradation are mostly lacking, except for photostability. The paper also offers criteria for selecting stress conditions and recommendations for conducting forced degradation studies throughout the different stages of therapeutic protein development.
