Validation: A Key Stage in Mobile Health Development

To enter the rapidly growing mobile health space, companies must overcome the Mobile Health Developmentcrucial hurdle of validation. This process demonstrates that the app – in combination with the underlying technology platform / device – performs comparably to traditional products on the market, ensuring that patients and providers can rely on the output to make appropriate medical decisions.

Mobile health apps offer functions ranging from data collection to running algorithms, and underlying all of those features is the need for a quality system. To show that their product is reliable, developers need to take a variety of measurements, confirm that data transmission and analysis work correctly and test the app on multiple devices.

Flow Cytometry Based Functional Assays Essential for Characterizing Biological Significance

The efficacy of immune-modulating anti-cancer therapeutic antibodies that have been FDA-approved in recent years, such as anti-CTLA-4 and anti-PD-1, has driven growing interest in methods that provide a mechanistic understanding of drug function. Development of new mono and combination therapies with immune-modulatory effects requires more powerful immunophenotyping techniques capable of in depth cell characterization. Flow-cytometry-based functional assays can be essential for elucidating the mechanism of a drug. While standard flow cytometry can identify immune subsets and their relative abundance within a sample, functional assays allow for the characterization of the biological significance of these populations including suppressive capability or activation status of a target population.

Understanding 505(b)(2): An Abbreviated Pathway for Modified Drugs

Among the regulatory pathways for small molecule drugs in the United States, the 505(b)(2) option occupies a middle ground. Intended for modifications of an existing505(b)(2): An Abbreviated Pathway for Modified Drugs Covance Blog treatment, it requires much more evidence than a generic but allows the sponsor to use data from a previous application. Companies can thus avoid unnecessarily repeating studies and shorten their development time.

At a recent Covance clinical seminar in Shanghai, attendees learned about the intricacies of 505(b)(2), the corresponding hybrid medicinal product pathway in the European Union and the differences from applications for biosimilars or generics. Developers in the Asia Pacific region are eager to better understand this topic because the Chinese pharmaceutical industry is developing rapidly with support from the government. “They view 505(b)(2) as a potentially faster way to market,” said Eric Lang, MD, Vice President and Global Head of Clinical Drug Development Leaders, Early Phase Development Solutions. To succeed, however, sponsors will need to consult with experts who can help them develop a regulatory strategy and consider market access issues as well. Continue reading
