Chimeric antigen receptor T-cell (CAR T) therapies are shown to have transformative potential as a new type of cancer treatment that utilizes the immune system to fight the disease. It involves the process where genetically engineered T cells (patient/donor) express a chimeric antigen receptor to target a specific tumor antigen. Although a major groundbreaking invention in the field of cancer treatment, CAR-T Cell Therapy’s application is limited to treating patients with select liquid tumors only in the refractory and relapsed stage and these combine only for 5% of the total cancer patients today. There are necessary areas where research & development are still lacking such as optimizing autologous CAR-Ts for liquid tumors, expanding the number of healthcare settings that administer CAR-T, shortening the innovation cycle time to enable success in solid tumors, and innovating in the manufacturing of next-generation CAR T-cell therapies. There are a total of 5 approved CAR T-cell therapies by the FDA and among those, 3 have also been approved by the EMA. Due to a lack of therapies, investment is required in the above-mentioned categories in order to unlock the potentiality of CAR T-cell therapies.


The pipeline of investigative CAR T-cell therapies has rapidly expanded with almost a thousand clinical trials underway in 2021. The earliest CAR T-cell therapy studies targeted the CD19 antigen whereas the ongoing clinical programs now target a wider range of molecules/antigens and include various tumor types. The tide that is carrying the market of the growing industry such as the CAR T-cell therapy is the availability of immense clinical data, for instance, pediatric and young adult patients with relapsed or refractory ALL achieved an overall remission rate of 90 percent at 12 months with treatment with an anti-CD19 autologous CAR T therapy.

CAR-T Cell Therapy Market & Driving Factors

Among the total market share of the overall T-cell therapy market, the CAR T-cell therapy market accounts for the maximum market share. The cause of the rising market for CAR T-cell therapy lies on the factors including an increasing prevalence of cancer which is expected to drive the production of CAR T-cells for use in therapeutic areas. Also, the possibility of artificial T-cell receptors application for the treatment of a wide variety of cancers has been widely acknowledged. This process also increases the usage of chimeric immunoreceptors as they assist  T-cells in finding and killing cancer cells that have the specific protein to which receptors can bind.

Continuous growth is observed in research & development in the life science and biotechnology sectors for the treatment of cancer using chimeric antigen receptors. There are extensive studies going on to validate the CAR T-cell therapy effectiveness and efficiency, mechanism of action, compliance in patients suffering from leukemia and lymphoma to CAR T-cell therapy in several countries.

Increased Revenue and Opportunities for Market Players in CAR T-Cell Therapy Domain

CAR T-cell therapy is a treatment process where T-cells are taken from the blood of the patient and then modified by adding a gene for a man-made receptor (chimeric antigen receptor). This helps in the recognition of some specific cancer cell antigens in a better way. Afterward, those CAR T-cells are given back to the patient. Different types of cancers have different types of antigens, and that is the main reason why each CAR T-cell is prepared in a different way for specific cancer antigens. The substantial and wide array of research and development gives significant opportunities to manufacturers to generate great revenue and invest in CAR T-cell therapy for targeting cancer cells.

Increased attention on research & development therapies for the treatment of various cancers such as lung, prostate, colorectal, and others is very likely to give rise to considerable growth opportunities for CAR T-cell therapy providers. Also, mergers and acquisitions play a significant role in accelerating a manufacturer’s strategy to capitalize and capture a significant share in the market. Then there are favorable government policies and fundings for pharmaceutical, life science companies which are anticipated to boost CAR T-cell therapy demand in the near future. Many key players who are proactively working in the CAR T-cell therapy market to continuously create new therapies include names like Bluebird Bio, Gilead Sciences Inc, Celgene Corporation, Pfizer Inc, Sensei Biotherapeutics, Amgen Inc, Novartis International AG, Helix BioPharma, Bellicum Pharmaceuticals Inc, Juventas Cell Therapy, Johnson & Johnson, Sangamo Therapeutics Inc, REGENERON, Novartis Pharmaceuticals, Takeda, among many others.

Approved CAR T-cell Therapies by the USFDA

Till date the FDA has approved the following five CAR T-cell therapies: 

Abecma (idecabtagene vicleucel) 

Abecma by  Celgene Corporation, a Bristol-Myers Squibb Company is a CAR T-cell therapy used to target refractory/relapsed Multiple Myeloma (MM) in adult patients who have earlier dealt with at least four more lines of therapy including an immunomodulatory agent, a proteasome inhibitor, and an anti-CD38 monoclonal antibody. It is based on a therapy namely – B-cell maturation antigen (BCMA)-directed genetically modified autologous chimeric antigen receptor (CAR) T-cell therapy. 

In every IV administered dose, a new gene is introduced specifically to target and kill Myeloma cells into the patient’s own genetically modified T-cells (WBCs). The safety and efficacy for the drug were reported in clinical trials of around 127 patients with refractory/relapsed Myeloma, where around 72% of people responded to the treatment either completely or partially. In March 2021, Abecma was approved by the U.S. Food and Drug Administration (FDA) for the treatment of multiple myeloma.

Breyanzi (lisocabtagene maraleucel)

Breyanzi– a CAR T-cell therapy manufactured by Juno Therapeutics, Inc., a Bristol-Myers Squibb Company isanother drug manufactured by the same parent company for the treatment of relapsed/refractory large B-cell lymphoma in adult patients. The patients must have earlier gone through two or more lines of systemic therapy, including diffuse large B-cell lymphoma (DLBCL), high-grade B-cell lymphoma, primary mediastinal large B-cell lymphoma, and follicular lymphoma grade 3B. The safety and efficacy of the drug were reported in clinical trials of around 250 adult patients with refractory/relapsed large B-cell lymphoma.After treatment, it was observed that the complete remission rate was 54%. An IV administered dosage of lisocabtagene maraleucel is targeted to induce selective toxicity in CD19-expressing tumor cells. It has become the 3rd gene therapy to be approved by the FDA for specific types of non-Hodgkin lymphoma, including diffuse large B-cell lymphoma. It came under medicinal use in February 2021.
