Outcomes and endpoints in clinical trials supporting the marketing authorisation of treatments in paediatric acute lymphoblastic leukaemia.

The improvement in acute lymphoblastic leukaemia (ALL) treatment has led research efforts to focus on the unmet medical needs of an increasingly smaller patient cohort with resistant leukaemia and to develop more-targeted agents. Survival and response rates remain the most-prevalent endpoints in paediatric ALL research, but other intermediate clinical endpoints and molecular biomarkers for efficacy and mid- and long-term safety endpoints are also being investigated. The success of current ALL treatment appears to be driving new paradigms to optimise clinical drug development, while at the same time, regulatory tools in place are supporting meaningful drug development in the area.

The changing landscape of treatment options in childhood acute lymphoblastic leukaemia.

New paediatric acute lymphoblastic leukaemia (ALL) treatments have been developed and innovative products are in the pipeline. However, despite many active clinical trials, bridging bench science to clinical development to authorised medicines remains challenging. Research in first-line treatment continues to focus on multidrug chemotherapy with the potential addition of new targeted molecules being studied. Research in second- and third-line treatment represents a shift from cytotoxic intensification to an area of precision medicine through emergent innovative and immuno-oncology products. The collaborative research model in ALL involving different stakeholders should intensify to facilitate bench-to-bedside clinical translation for the benefit of patients.

Improving the data quality of spontaneous ADR reports: a practical example from Malta.

BACKGROUND: Adverse drug reaction (ADR) reporting rates and high-quality data within case summary reports are crucial to detect emerging safety concerns and implement regulatory action. In this study we aimed to improve the data quality and reporting rates of ADR reports in Malta through a series of national activities. RESEARCH DESIGN AND METHODS: Between April 2018 and July 2019, we carried out the following activities: i) a review of wholesale dealers ADR reporting forms; ii) a series of educational workshops targeting physicians and pharmacists; iii) a quality system audit of the Authority's ADR management process. RESULTS: Twelve wholesaler dealer forms were reviewed, and 155 improvements were identified. Incident reporting forms modified to capture ADRs had the most opportunities for improvement. Five workshops were organized and in total 62 physicians and 22 pharmacists attended. Although feedback from participants was positive, in our case, an increase in reporting was not observed following the workshops. The quality system audit resulted in the introduction of the 'four-eye principle' to the Authority's ADR management process. CONCLUSIONS: The implementation of such activities is expected to contribute to the overall pharmacovigilance systems in Malta and our experience could benefit other entities involved in spontaneous ADR reporting.

Regulatory experience of handling Risk Management Plans (RMPs) for medicinal products in the EU.

Introduction: Risk Management Plans (RMPs) aim to optimize a medicinal product's benefit/risk balance for the individual patient and the target population. Despite differences in regulatory RMP requirements between jurisdictions worldwide, their ultimate aim is to protect public health.Areas covered: The review presents findings of different RMP requirements by different regulatory authorities and additional risk minimization measures (issued between January 2010 and December 2018) indicate how RMPs and additional risk minimization measures translate into actions to protect public health within the European Union (EU) member states and worldwide. Areas covered also include the different International Council for Harmonization (ICH) regional requirements of RMPs by the different regulatory authorities as well as data regarding the number of RMP assessments carried out by the EMA, FDA and Japan, and number of safety communications issued in Malta (taken as an example of a typical small EU member state) and in the United States of America (USA).Expert opinion: The EU legislation adopted in 2010 required RMPs to be included in all new applications for medicinal products in the EU, both for EU centrally authorized and nationally authorized medicinal products. Lessons learnt by EU regulators during this process are discussed in this review.
