Cell and gene therapies are rapidly transforming the therapeutic landscape, particularly in oncology, where they have emerged as powerful tools for addressing hematologic malignancies and, increasingly, solid tumors. With annual growth projected at 36% through 2030 and 10 to 20 new approvals expected each year, oncology pharmacists are likely to encounter these therapies more frequently across care settings.1
A Growing Approval Footprint
As of December 2024, 106 cell therapy products have been approved globally: 33 gene therapies (13 of which are genetically modified cell therapies) and 73 non–genetically modified cell therapies.2-4 In the United States, the FDA had approved 44 cell therapy products as of March 6, 2025.5 This growing portfolio includes treatments for a wide range of cancers, with an expanding footprint into autoimmune and degenerative conditions.
Development Trends: Oncology at the Forefront
Gene therapy currently ranks third among therapeutic focus areas, with 2151 compounds in development in 2024 (Figure). Of these, 1192 are classified as genetically modified cell therapies, reflecting the convergence of gene and cell platforms.6 Chimeric antigen receptor (CAR) cell therapies ranked 10th with 795 candidates, holding steady from 2023.6
CAR T-cell therapies continue to dominate the genetically modified space. They account for 32% of total cell and gene therapy pipelines and target cancer treatment in 97% of cases.4,7 Meanwhile, non–genetically modified cell therapies—including mesenchymal and stem cell products—represent 32% of the pipeline and are primarily being explored for regenerative medicine and nononcology rare diseases.4
Oncology indications remain the primary focus across modalities. The most targeted cancers include acute myeloid leukemia, liver cancer, and pancreatic cancer.4 Nononcology applications are growing, however, particularly for conditions such as osteoarthritis, type 1 diabetes, and Parkinson disease.
Adoptive Cell Therapy: CAR T, TIL, and TCR Approaches
Adoptive cell therapies (ACTs)—namely CAR T, tumor-infiltrating lymphocyte (TIL), and T-cell receptor (TCR) therapies—have seen fluctuating pipeline activity, peaking in 2022 and declining slightly since.8 Most CAR T-cell therapies focus on hematologic malignancies, with non-Hodgkin lymphoma, acute lymphoblastic leukemia, and multiple myeloma leading development. Solid tumor targets are more prevalent in TIL and TCR programs, which focus on gastrointestinal, lung, and skin cancers.1,8
CD19, B-cell maturation antigen, and CD22 are the most common targets in oncology pipelines, with other notable targets including CD20, HER2, CD30, CD33, and CD123.1 Nononcology programs increasingly target VEGF and other inflammatory mediators.9
Regulatory Pipeline and Late-Stage Candidates
A substantial number of therapies are nearing market. Among non–genetically modified cell therapies, 43 are in phase 3 trials and 3 are in preregistration.2 For genetically modified cell therapies, 7 are in phase 3 and 5 are in preregistration. Currently, 68% of all approved cell therapy products fall under the non–genetically modified category.2
