Abstract

Advancing therapeutic discoveries through early clinical studies benefits from a working knowledge of regulatory history, practices, provisions, procedures and controversies. This chapter aims to supplement available published and web-based resources that describe current regulatory expectations and requirements. Though the Food and Drug Administration (FDA) is emphasized for illustrative purposes, the importance of the European Medicines Agency (EMA) and other regional authorities should not be minimized. Some relevant differences between EMA and FDA are also discussed. With emphasis on early studies, selected regulatory considerations are presented for developing diabetes, anti-obesity and lipid-lowering therapies towards existing therapeutic indications. Regulatory and clinical trial considerations are provided for developing novel therapeutic indications including those for nonalcoholic steatohepatitis (NASH) and related disorders.

    Ironically, the title could not be completely harmonized. The British/French spelling continues to be used in the official international title. FDA uses the American spelling.

  2. 2.

    FDA adopted the ICH reports as guidances to avoid the much longer period of time that would have been required to makes these laws or regulations.

    The current U.S. system of protection for human research subjects is heavily influenced by the Belmont Report, https://www.hhs.gov/ohrp/regulations-and-policy/belmont-report/index.html written in 1979 by the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research. The Belmont Report outlines the basic ethical principles in research involving human subjects. In 1981, with this report as foundational background, HHS and the Food and Drug Administration revised, and made as compatible as possible under their respective statutory authorities, their existing human subjects regulations. The Federal Policy for the Protection of Human Subjects or the “Common Rule” was published in 1991 and codified in separate regulations by 15 Federal departments and agencies, as listed below. The HHS regulations, 45 CFR part 46, include four subparts: subpart A, also known as the Federal Policy or the “Common Rule”; subpart B, additional protections for pregnant women, human fetuses, and neonates; subpart C, additional protections for prisoners; and subpart D, additional protections for children. Each agency includes in its chapter of the Code of Federal Regulations [CFR] section numbers and language that are identical to those of the HHS codification at 45 CFR part 46, subpart A. For all participating departments and agencies, the Common Rule outlines the basic provisions for IRBs, informed consent, and Assurances of Compliance. Human subject research conducted or supported by each federal department/agency is governed by the regulations of that department/agency. The head of that department/agency retains final judgment as to whether a particular activity it conducts or supports is covered by the Common Rule. If an institution seeks guidance on implementation of the Common Rule and other applicable federal regulations, the institution should contact the department/agency conducting or supporting the research. https://www.hhs.gov/ohrp/regulations-and-policy/regulations/common-rule/index.html

    “In 2012, Congress passed the Food and Drug Administration Safety Innovations Act (FDASIA). Section 901 of FDASIA amends the Federal Food, Drug, and Cosmetic Act (FD&C Act) to allow the FDA to base accelerated approval for drugs for serious conditions that fill an unmet medical need on whether the drug has an effect on a surrogate or an intermediate clinical endpoint.” https://www.fda.gov/ForPatients/Approvals/Fast/ucm405447.htm
