What is cell and gene therapy?

During cellular replication, if genes become mutated or duplicated, an opportunity for disease can be created. By using cells and genes as therapeutic agents, it is possible to deliver durable cures. Instead of more traditional approaches such as small molecules and biologics that treat symptoms, these "living drugs" can persist in the patient for many years or potentially a lifetime. "Cell and gene therapy" is a single approach to addressing disease, but the potential methods for delivering treatments differ. This complex technology is quickly evolving and facing multiple challenges; quality and safety are paramount, and time is precious. Cell and gene therapies offer hope for many, as they are enhancing and saving the lives of people who often have no other treatment option.

Cell therapy utilizes living cells form the patient or a donor to replace damaged or diseased cells or to stimulate the body’s immune response or regeneration. Usually stem cells and immune cells are used, and a typical method involves removing the cells from the body, repairing or editing the error in the gene, and then returning the cells to the body. When cells undergo gene editing outside of the body and then returned to the body, this is referred to ex vivo gene therapy.

Gene therapy treats diseases with genetic material to change or supplement a gene whose absence or abnormality is causing the disease. Treatments can happen outside the body (ex vivo) or inside the body (in vivo).

As you move your stem cell, immunotherapy or gene therapy research toward the clinic, your product selection, lab process, documentation, and quality assurance steps become more demanding. This collection of resources will help you gain a better understanding of cell and gene therapy research, feel confident at every step, and maximize your time, effort, and clinical outcomes.
