Abstract:
CAR-T cells showed great potential in the treatment of patients with hematologic tumors. However, the clinical efficacy of CAR-T cells against solid tumors lags behind. To obtain a comprehensive overview of the landscape of CAR-T cell clinical trials against this type of cancer, this review summarizes all the 196 studies registered at clinicaltrials.gov. Special focus is on: (1) geographical distribution; (2) targeted organs, tumor entities, and antigens; (3) CAR transfer methods, CAR formats, and extra features introduced into the T cells; and (4) patient pretreatments, injection sites, and safety measurements. Finally, the few data on clinical outcome are reported. The last assessment of clinicaltrials.gov for the data summarized in this paper was on 4 August 2020.
Insights
Chimeric antigen receptor T cell (CAR-T) therapy shows promise for blood cancers but struggles with solid tumors. This review analyzes 196 clinical trials to map CAR-T research for solid tumors.
Area of Science:
- Immunotherapy
- Oncology
- Clinical Trials
Background:
- CAR-T cell therapy has revolutionized hematologic cancer treatment.
- Significant challenges remain in translating CAR-T efficacy to solid tumors.
- A comprehensive overview of ongoing CAR-T clinical trials for solid tumors is needed.
Purpose of the Study:
- To provide a comprehensive overview of the CAR-T cell clinical trial landscape for solid tumors.
- To analyze geographical distribution, targets, and methodologies of these trials.
- To report available clinical outcome and safety data.
Main Methods:
- Systematic review of 196 studies registered on clinicaltrials.gov.
- Analysis focused on geographical distribution, targeted organs, tumor entities, and antigens.
- Examination of CAR transfer methods, CAR formats, T cell modifications, patient pretreatment, administration sites, and safety measures.
Main Results:
- The review details the geographical distribution of CAR-T trials for solid tumors.
- It identifies targeted organs, tumor entities, and specific antigens being investigated.
- Information on CAR design, T cell engineering, and clinical trial logistics is presented, alongside limited outcome data.
Conclusions:
- CAR-T cell therapy for solid tumors is an evolving field with diverse strategies.
- Understanding the current landscape is crucial for advancing clinical development.
- Further research and data on clinical outcomes are necessary to overcome challenges.
