- Introduction:
Cell and Gene Therapy (CGT) is an advanced area of medicine that uses genetic modification and cellular engineering to treat or cure diseases, particularly those with limited treatment options. It includes two main approaches:
- Cell Therapy – The use of living cells to repair, replace, or regenerate damaged tissues or organs. Examples include:
- CAR-T cell therapy (e.g., Kymriah, Yescarta) for cancer treatment
- Stem cell therapies for regenerative medicine
- Gene Therapy – The modification of genetic material to treat or prevent disease by inserting, deleting, or correcting faulty genes. Examples include:
- Luxturna for inherited retinal disease
- Zolgensma for spinal muscular atrophy
Certain treatments fall under both cell and gene therapy categories. These therapies function by modifying genes within specific cell types before introducing them into the body.
This combined approach addresses some limitations of using gene or cell therapy individually. Utilizing a patient’s own cells eliminates the need for a donor match, and modifying cells in a laboratory setting is often more manageable than making genetic changes directly within the body.
2. Key Trends & Advancements in CGT
​The Cell and Gene Therapy (CGT) sector is experiencing rapid advancements, marked by significant trends that are reshaping the landscape of medical treatment. Key developments include:​
- Expansion of Approved Therapies
