Overview of Cellular Therapeutics Clinical Trials: Advances, Challenges, and Future Directions

Area of Science:

• Regenerative Medicine
• Immunotherapy
• Oncology

Background:

• Cellular therapeutics, including stem cells and engineered immune cells, show efficacy but face low engraftment and limited long-term success.
• Translational barriers hinder the clinical application of cell therapies.

Purpose of the Study:

• To review clinical cell therapy projects in China over the past five years.
• To analyze global clinical achievements and identify therapeutic improvements.
• To propose integrating traditional Chinese medicine (TCM) to enhance cell therapy efficacy.

Main Methods:

• Compilation of clinical projects on cell therapy in China (172 trials, >1200 patients).
• Analysis of published global clinical achievements in cell therapy.
• Review of proposed mechanisms for TCM integration (CXCR4 upregulation, mitochondrial biogenesis).

Main Results:

• Significant therapeutic improvements observed in degenerative disorders (40-60% WOMAC score improvement) and oncology (78% ctDNA clearance).
• Rapid development and diverse applications of cell therapy highlighted.
• Identified limitations in TCM validation (72% lacking single-cell omics) and regulatory issues.

Conclusions:

• Cellular therapeutics offer significant therapeutic potential, particularly in degenerative diseases and oncology.
• Integrating TCM bioactive compounds presents a promising strategy to enhance cell viability and overcome translational barriers.
• Future research should focus on randomized trials and standardized TCM-cell therapy protocols to facilitate clinical translation.
