Adoptive gamma delta (γδ) T cell therapy is a novel type of immunotherapy that utilizes a unique subset of T cells to recognize and destroy cancer cells. While typical alpha-beta (αβ) T cells identify antigens presented by major histocompatibility complex (MHC) molecules, γδ T cells are activated by stress induced ligands and phosphoantigens in an MHC independent fashion. This enables them to detect and target a wide variety of tumor types, including those that are not targeted by conventional immune vigilance. γδ T cells possess characteristics of both innate and adaptive immunity, allowing them to have the ability for immediate response and immune memory, which make them particularly good candidates for off-the-shelf adoptive cell therapies.

In cancer, γδ T cells are under investigation for their potential to destroy malignant cells without the requirement of tumor-specific antigens or genetic modifications, which are technically demanding and expensive. Their intrinsic cytotoxicity, along with the possibility of allogeneic utilization (from healthy donors), provides access to the availability of mass producible, inexpensive therapies. The majority of clinical research and development to date has been in hematological malignancies, where they have been especially promising. γδ T cells are able to penetrate the bone marrow and other lymphoid organs and exert tumor effects there through cytokine release, direct cytotoxicity, and changing the microenvironment of the tumor.

The demand for novel cancer therapies is pressing, especially in blood cancers like acute myeloid leukemia (AML), which tend to relapse or are resistant to conventional therapies. Options for patients who relapse following remission or who have residual disease (MRD) are limited, and prognosis is usually poor. γδ T cell therapies are in a unique position to bridge this gap, providing a potentially effective, safe, and off-the-shelf product that can be delivered without the logistical issues of autologous T cell therapies, including manufacturing hold-ups or patient variability.

TC Biopharm is leading the way in clinical development in this area. The company's most advanced product candidate, OmnImmune (formerly TCB-002), is in a pivotal Phase 2/3 trial for AML. OmnImmune is an allogeneic γδ T cell therapy engineered to quickly target and destroy cancer cells while avoiding damage to normal tissue. This clinical program is one of the most advanced in the global γδ T cell pipeline, highlighting TC Biopharm's growing leadership within the domain. Besides OmnImmune, the company has a number of other γδ T cell candidates in development for various cancer indications.

One of the most significant recent advances from TC Biopharm is the development of its candidate TCB008, which is under investigation in the Phase 2 ACHIEVE trial. The firm reported in June 2025 that the first patient in Cohort B, who had relapsed previously with detectable MRD, reached complete molecular remission following two doses. A lack of detectable NPM1 transcripts after treatment signifies a profound and lasting response, which identifies TCB008 as a promising post-remission therapy for blood cancers. This achievement demarcates the potent, targeted immune function of γδ T cells and substantiates their role as a new therapeutic strategy.

Globally, most of the research studies on γδ T cells remains on hematologic malignancies, and there are fewer programs directed at solid tumors. This is partly a result of the more sophisticated microenvironments and the immune evasion mechanisms utilized by solid cancers. However, attempts are being made to apply γδ T cell treatments to these more difficult contexts. Geographically, US-based players dominate the γδ T cell therapy market, followed by increasing numbers of Chinese firms. These regions have made heavy investment in cell therapy facilities and technology, facilitating quicker translation from bench to bedside.

Moving forward, the prospects for γδ T cell therapy are bright but will necessitate continued clinical validation, most importantly in solid tumors. With advances in manufacturing technologies and biomarker-driven strategies, the use of γδ T cells may extend to more types of cancers. With leaders such as TC Biopharm at the forefront, the field is on track to provide life changing treatments for critical unmet needs in cancer domain.
