Advancing the Integration of Digital Health Technologies in the Drug Development Ecosystem.

Optimized frameworks for efficient and scalable deployment of digital health technologies (DHT) are needed to address existing bottlenecks and unlock the opportunities for remote monitoring and operationalizing decentralized trials. DHTs offer immense potential opportunities for transformation in drug development by providing remote, high frequency, longitudinal insights into physiological processes, and how participants feel and function. Currently, DHT-based drug development tool-related efforts have yielded valuable insights into effective practices and areas that need improvement.

Can Innovative Trial Designs in Orphan Diseases Drive Advancement of Treatments for Common Neurological Diseases?

Global regulatory agencies have transformed their approach to approvals in their processes for formal review of the safety and efficacy of new drugs. Opportunities for innovation have expanded because of the coronavirus disease 2019 (COVID-19) pandemic. Several regulatory-led initiatives have progressed rapidly during the past year, including patient-focused drug development, model-informed drug development, real-world evidence, and complex innovative trial designs.

The Use of External Controls in FDA Regulatory Decision Making.

The regulatory standards of the United States Food and Drug Administration (FDA) require substantial evidence of effectiveness from adequate and well-controlled trials that typically use a valid comparison to an internal concurrent control. However, when it is not feasible or ethical to use an internal control, particularly in rare disease populations, relying on external controls may be acceptable. To better understand the use of external controls to support product development and approval, we reviewed FDA regulatory approval decisions between 2000 and 2019 for drug and biologic products to identify pivotal studies that leveraged external controls, with a focus on select therapeutic areas.

Wearable Technologies for Children with Chronic Illnesses: An Exploratory Approach.

Objective: To determine the utility of wearable technologies in physical activity assessment in three paediatric diseases, namely, Niemann-Pick C (NP-C), Juvenile Idiopathic Arthritis (JIA) and Duchenne Muscular Dystrophy (DMD).

Design: Exploratory study SETTING AND PATIENTS: Thirty children were recruited across three UK hospitals (Royal Manchester's Children Hospital, Great Ormond Street Children's Hospital, and the Great North Children's Hospital). Ten were diagnosed with NP-C, eight with DMD and twelve with JIA.

Pediatric Extrapolation in Type 2 Diabetes: Future Implications of a Workshop.

Extrapolation from adults to youth with type 2 diabetes (T2D) is challenged by differences in disease progression and manifestation. This manuscript presents the results of a mock-team workshop focused on examining the typical team-based decision process used to propose a pediatric development plan for T2D addressing the viability of extrapolation. The workshop was held at the American Society for Clinical Pharmacology and Therapeutics (ASCPT) in Orlando, Florida on March 21, 2018.

Commentary on the EMA Reflection Paper on the use of extrapolation in the development of medicines for paediatrics.

Adopted guidelines reflect a harmonised European approach to a specific scientific issue and should reflect the most recent scientific knowledge. However, whilst EU regulations are mandatory for all member states and EU directives must be followed by national laws in line with the directive, EMA guidelines do not have legal force and alternative approaches may be taken, but these obviously require more justification. This new series of the BJCP, developed in collaboration with the EMA, aims to address this issue by providing an annotated version of some relevant EMA guidelines and regulatory documents by experts.

Paediatric extrapolation: A necessary paradigm shift.

Legislative initiatives have been successful in increasing the availability of approved therapies for paediatric patients. However, additional measures to ensure the timely completion of paediatric studies are necessary to further increase the number of medicines available to children. Over the last 3 years, international experts convened to revise the ICH E11 guideline on clinical investigations of medicinal products in paediatric populations to harmonize approaches to paediatric extrapolation, striving to reduce substantial differences between regions in the acceptance of data for global paediatric medicine development programmes.

Paediatric investigation plans for pain: painfully slow!

Purpose: To examine the early impact of the Paediatric Regulation, which entered into force in Europe on 27 January 2007, on the development of pharmaceutical drugs in the therapeutic field of pain submitted to the Paediatric Committee (PDCO) and to the European Medicines Agency (EMA).

Methods: Paediatric Investigations Plans (PIPs) submitted with a Decision (outcome) reached between September 2007 and March 2010 were included in the analysis.

Results: Of the 17 Paediatric Investigation Plans submitted, 14 have resulted in an EMA Decision, 3 were withdrawn by the applicants, 8 were granted a full waiver from development, and 1 resulted in a negative opinion.

Typing of Scedosporium apiospermum by multilocus enzyme electrophoresis and random amplification of polymorphic DNA.

The genetic diversity among epidemiologically unrelated strains of the human pathogenic fungus Scedosporium apiospermum or its teleomorph, Pseudallescheria boydii, from different areas in Europe, was investigated by multilocus enzyme electrophoresis (MLEE) and random amplification of polymorphic DNA (RAPD). Fourteen enzyme activities were analysed by starch gel electrophoresis, corresponding to 27 polymorphic loci and 43 iso-enzymes. Among the enzymes studied, propionate esterase, carboxyl esterase, superoxide dismutase, carbonate dehydratase and malate dehydrogenase were the most polymorphic, allowing the classification of the strains into 6-11 groups each.
