title: Immune monitoring of clinical trials with biotherapies.
abstract: Immune monitoring of biotherapy clinical trials has undergone a considerable change in recent years. Technical advances together with new insights into molecular immunology have ushered a new genre of assays into immune monitoring. Single-cell assays, multiplex profiling, and signaling molecule detection have replaced formerly used bulk assays, such as proliferation or cytotoxicity. The emphasis on immune cell functions and quantitation of antigen-specific T cells has been playing a major role in attempts to establish correlations between therapy-induced alterations in immune responses and clinical endpoints. However, this has been an elusive goal to achieve, and there is a special need for improving the quality of serial monitoring to ensure that it adequately and reliably measures changes induced by administered biotherapy. In this respect, monitoring performed in specialized reference laboratories operating as good laboratory practice (GLP) facilities and strengthening of interactions between the clinical investigator, the clinical immunologist, and the biostatistician are crucial for successful use of immune monitoring in clinical studies.
