Risk management of biosimilars in oncology: each medicine is a work in progress

Drug licensing and drug safety monitoring for standard chemical entities have been established and are routinely used. These have resulted in a solid foundation of knowledge from which confident therapeutic decisions can be made. For many chemical entities, this advanced level of experience is also present for the generic products. The expertise surrounding the development of biosimilar competitor versions is increasing and progress is encouraging. To address the re-engineering and comparability complexities of biosimilars, the European Union imposed a requirement that risk management plans be included in the medications’ marketing applications. This paper summarizes and discusses the circumstances complicating the public’s view of drug safety, historical incidents during the transition from innovative to competitor products, as well as retrospective assessments of the development and post-marketing experiences thus far with two biosimilars. Through assessing the market entries and post-marketing experiences of biosimilars used in oncology, the healthcare field can better prepare for the next wave of comparator-products: biosimilar monoclonal antibodies

Effects of the 5-HT2C receptor agonist meta-chlorophenylpiperazine on appetite, food intake and emotional processing in healthy volunteers

RATIONALE: The treatment of obesity is an increasing global health priority, yet few effective drug treatments are currently available. The discovery of novel anti-obesity therapies could be assisted by the validation of experimental (translational) medicine models in healthy volunteers that assess efficacy and safety at an early stage of drug development. OBJECTIVES: The aim of this study was to examine the effects of the 5-HT2C receptor agonist meta-chlorophenylpiperazine (mCPP) in an experimental medicine model assessing both appetite and mood. METHODS: Using a between-subjects, double-blind, placebo-controlled design, 24 male and 24 female participants were randomly assigned to either placebo, 15- or 30-mg mCPP treatment groups. Lunch was eaten from a Universal Eating Monitor (UEM) that measured eating rate, and the participants completed the P1vital® Oxford Emotional Test Battery (ETB) and a series of appetite and mood ratings. RESULTS: mCPP reduced appetite and, in women, enhanced measures of satiation. The drug also enhanced memory for emotional material in the word recall and recognition memory tasks of the ETB. CONCLUSIONS: The results provide new insight into the effects of mCPP on appetite, satiety and memory in humans. In addition, our data provide an illustration of the value of measuring changes in appetite and mood in healthy volunteers to determine the potential efficacy and safety of novel anti-obesity drugs

Exploring well-being: medical students and staff.

BackgroundMental illness in young people is a major public health challenge, with a higher prevalence amongst medical students. This study explores the perspectives of both students and staff in relation to the provision of well-being support within one medical school in the United Kingdom.MethodsA total of 17 second-year medical students and five members of academic and well-being staff at Liverpool Medical School participated in one-to-one semi-structured interviews. Staff and students were asked for their views on existing support services, exploring challenges and ideas for development. Interviews were recorded, transcribed and analysed thematically to identify common themes amongst both students and staff.ResultsStudents wanted to have more obvious support during their transition from sixth form to undergraduate studies. Perceived stigma surrounding mental health continues to prevent students seeking help over concerns this might have upon academic progress. Staff reported concerns that student expectations did not always match with what could realistically be provided by the medical school well-being service.DiscussionThe provision of opportunities for students to 'check-in' with staff, and the introduction of well-being topics within the curriculum, were perceived by students and staff as being of potential benefit to the mental health of students. Such interventions may also help to build rapport and encourage students to engage with medical school support services. All well-being support services are increasingly in demand amongst medical students, showing a need for them to expand and well-being to be further incorporated into the course
