Randomised controlled trials (RCTs) are considered to be the gold standard in evaluating medical interventions; however, people from ethnic minorities are frequently under-represented in such studies. The present paper addresses a previously neglected debate about the tensions which inform clinical trial participation amongst people from ethnic minorities, in particular, South Asians, the largest ethnic minority group in the UK. In a narrative review of the available literature, based mainly on US studies, the present authors aim to make sense of the issues around under-representation by providing a theoretical reconciliation. In addition, they identify a number of potential barriers to ethnic minority participation in clinical trials. In so doing, the authors recognise that the recent history of eugenic racism, and more general views on clinical trials as a form of experimentation, means that clinical trial participation among people from ethnic minorities becomes more problematic. Lack of participation and the importance of representational sampling are also considered, and the authors argue that health professionals need to be better informed about the issues. The paper concludes by offering a number of strategies for improving ethnic minority accrual rates in clinical trials, together with priorities for future research. [ABSTRACT FROM AUTHOR]

Chimeric antigen receptor- (CAR-) based immunotherapy has been under development for almost 25 years, over which period it has progressed from a new but cumbersome technology to an emerging therapeutic modality for malignant disease. The approach involves the genetic engineering of fusion receptors (CARs) that couple the HLA-independent binding of cell surface target molecules to the delivery of a tailored activating signal to host immune cells. Engineered CARs are delivered most commonly to peripheral blood T cells using a range of vector systems, most commonly integrating viral vectors. Preclinical refinement of this approach has proceeded over several years to the point that clinical testing is now being undertaken at several centres, using increasingly sophisticated and therapeutically successful genetic payloads. This paper considers several aspects of the pre-clinical and clinical development of CAR-based immunotherapy and how this technology is acquiring an increasing niche in the treatment of both solid and haematological malignancies.

The National Cancer Research Network (NCRN) was created in 2001 to improve the infrastructure for cancer research within the National Health Service (NHS) in the UK and ensure that research is better integrated with cancer care. The NCRN consists of 34 regional networks which map onto the 34 cancer networks that were established following the publication of the NHS Cancer Plan with its aim of improving the coordination and delivery of cancer care and treatment nationally. An objective of the NCRN is to increase recruitment into cancer trials through improved support. One cancer research network responded by introducing Clinical Trial Officers (CTOs) into the cancer clinical trial setting in order to combine the range of tasks required to support clinical trials into a single role with the ultimate aim of increasing recruitment into cancer clinical trials. Evaluation during the first 14 months of their introduction assessed the impact of the new CTO role on cancer trial recruitment, its acceptability to those involved in trials and its effectiveness in achieving increased recruitment. Evaluation identified appropriate induction and training programmes required to support these new roles and the identification of a model for the introduction of CTO posts in other networks across the country. The findings presented in this paper identify that CTO roles can effectively be introduced into a cancer network and have an impact on recruitment to clinical trials within that network. The data collected provided an in-depth insight into how these roles were perceived, have developed and what supporting structures need to be in place to enable them to flourish. Recruitment in the network has increased and there has been a raising of awareness of clinical trials and cancer research across the whole of the cancer network where the CTOs were based. We conclude that CTO roles can offer a creative alternative to staffing cancer clinical trial units and that such a model could be introduced across other networks. Similar models could also be introduced into other disease settings where clinical research is taking place. [ABSTRACT FROM AUTHOR]
