Chimeric Antigen Receptor T-cell (CAR-T) therapy has emerged as a ground-breaking
approach in cancer treatment, offering new hope to patients with refractory or relapsed malignancies.
By genetically modifying T lymphocytes, this potent method allows for the targeted eradication of
infectious cells. The efficient production of CAR-T cells is essential for the effective use of these
treatments to treat malignancies, as it affects not just the product's efficacy as well as safety but also
its general availability to patients who require it. This article's primary goal is to provide a comprehensive
overview of CAR-T therapy, encompassing its historical evolution, mechanistic insights,
clinical applications, challenges, and future directions. By synthesizing existing literature and realworld
evidence, this review seeks to elucidate the significance of CAR-T therapy in the landscape of
cancer treatment and its potential to redefine the standard of care for patients with refractory or relapsed
malignancies. The methodology involved a comprehensive literature search conducted using
various databases, including PubMed, Google Scholar, and clinical trial registries such as Clinical-
Trials.gov. The search strategy incorporated a combination of relevant keywords and Medical Subject
Headings (MeSH) terms, including but not limited to "CAR-T therapy," "chimeric antigen receptor
T-cell therapy," "cancer immunotherapy," "clinical trials," "pharmaceutical companies," "regulatory
approvals," "pipeline molecules," and "cancer types." Boolean operators (AND, OR) were utilized to
refine the search and capture relevant articles and studies. In addition to database searches, manual
screening of reference lists from relevant review articles and primary studies was performed to identify
additional relevant publications. The inclusion criteria encompassed original research articles, clinical
trials, systematic reviews, meta-analyses, and regulatory documents related to CAR-T cell therapy
and its applications in cancer treatment and the review included studies published in English between
January 2010 and March 2024. Exclusion criteria comprised studies not relevant to the scope
of the review, such as those focusing on non-CAR-T cell therapies or non-cancer-related topics. This
review underscores the transformative potential of CAR-T therapy in cancer treatment, highlighting
its efficacy, safety, and clinical relevance across various malignancies. By synthesizing findings from
preclinical studies, clinical trials, and real-world data from patients, CAR-T therapy has consistently
exhibited remarkable therapeutic outcomes. These include high response rates, durable remissions,
and significant improvements in survival outcomes among patients with refractory or relapsed cancers.
Additionally, the inclusion of practical research with big data from real patients further supports
the robustness and applicability of CAR-T therapy in clinical practice. In conclusion, CAR-T therapy
represents a paradigm shift in cancer treatment, offering new avenues for personalized and precisiondriven
oncology. By addressing current gaps, optimizing treatment protocols, and exploring novel
strategies, CAR-T therapy holds immense promise in reshaping the landscape of oncology and
providing hope to patients with advanced malignancies.
