what are the top CIK therapy companies?

Introduction to CIK Therapy

Cytokine‐induced killer (CIK) cells are a heterogeneous population of immune effector cells typically characterized by a mixed T‐cell and natural killer (NK) cell phenotype, usually expressing both CD3 and CD56 surface markers. They are generated ex vivo by stimulating peripheral blood mononuclear cells (PBMCs) with a combination of cytokines such as interferon‐γ (IFN-γ) and interleukin-2 (IL-2) along with an anti-CD3 antibody. This process results in cells that possess a unique mode of tumor cell recognition: the ability to kill target tumor cells via major histocompatibility complex (MHC)-unrestricted pathways by engaging receptors such as NKG2D, NKp30, and DNAM-1. By harnessing both innate and adaptive immune mechanisms, CIK cells are able to recognize and eliminate a broad spectrum of malignancies with minimal off‐target effects, making them attractive for adoptive immunotherapy applications.

Historical Development 
CIK cell therapy has evolved over the past three decades. Since its first description in the early 1990s, researchers observed that these cells could be expanded ex vivo to clinically relevant doses, a feat that was more challenging with other effector cells like primary NK cells due to their limited proliferative capacity. Over the years, clinical trials involving CIK cells have been conducted in various tumor settings ranging from hematological malignancies to solid tumors including colorectal, lung, and hepatocellular carcinoma. Early clinical studies demonstrated not only the feasibility and safety of infusing ex vivo expanded CIK cells but also showed signs of improved overall survival and progression-free outcomes in several cancer types. Advances in the culture optimization, combination strategies (such as the addition of dendritic cells to form DC-CIK vaccines), and genetic engineering (for example, the addition of chimeric antigen receptors or CARs) have further broadened the applicability of CIK cell therapy. This timeline reflects a journey from bench research to clinical translation and now to advanced combinatorial and genetically enhanced strategies.
