Non-inferiority, superiority, or both? Operationalizing the FDA guidance
Speaker: Marc PFEFFER, Boston, USA
Discussant: Stuart POCOCK, London, GBR
Regulatory viewpoint: Kristina DUNDER, EMEA, SWE
Abstract : The evaluation of cardiovascular safety of rosiglitazone (2006-2010) had implications on regulatory guidance for glucose lowering drugs both in the EU and in the US and both the FDA and the CHMP guidelines for development of glucose lowering drugs have been updated including new requirements for assessment of cardiovascular safety. While the FDA Guidance is very precise specifying that the upper bound of the 95% confidence interval for the estimated risk should be below 1.8 at the time of marketing application, the CHMP guidance focuses more on the
totality of data as a base for assessing the cardiovascular risk.
The presentation will focus on the interpretation of the requirements in the CHMP guideline (type of studies, study population, outcome measures, evaluation of the results) as well as experience from recent applications for marketing authorization for glucose lowering drugs, e.g. the usefulness of MACE meta analyses and the need for CV outcome studies for all new drugs.

Diabetes clinical trials : helped or hindered by the current shift in regulatory requirements? Glycaemic control is an inadequate surrogate marker of cardiovascular event reduction in patients with type 2 diabetes. Clinical trials to date have been unsuccessful in identifying a therapeutic approach that addresses the underlying problem in diabetes (glycaemic control) and reduces cardiovascular risk. The potential for some agents to increase the risk of cardiovascular events has led to substantial changes in regulatory requirements for new anti-diabetic therapies. These requirements, while key to ensuring the cardiovascular safety of new agents, fail to emphasize the need to show clinical benefits, such as less visual impairment, less need for dialysis, or fewer cardiovascular events and deaths. Changes in test results such as glycaemic control, serum creatinine, micro-albuminuria, or retinopathy are inadequate surrogates. Regulators should consider the potential advantages of offering extended patent protection in order to encourage companies to conduct long-term trials in diabetes and many other chronic medical conditions. Cooperative efforts among physicians, clinical trialists, regulators, and sponsors are needed to address unresolved issues including re-defining therapeutic targets that are meaningful to patients with diabetes, determining the appropriate length of follow-up for future trials, and considering the ethical and operational challenges of non-inferiority designs.

ROLE:author
NOTE:DUNDER Kristina, EMEA, SWE&lt;br&gt;Dr Dunder graduated from Uppsala University (School of Medicine) in 1988. She specialized in internal medicine and endocrinology/diabetology and served as a medical doctor at the Uppsala Academic Hospital until 2005. In 2004 she defended a thesis with the title “Clinical manifestations of coronary heart disease and the metabolic syndrome”. Since 2005 Dr Dunder holds a position as a clinical assessor and senior expert at the Medical Product Agency in Uppsala, Sweden. She is currently the Swedish delegate in the CHMP (Committee of Human Medical Products) at the EMA (European Medicine Agency) in London, UK and a member of the cardiovascular working party at the EMA. Dr Dunder was one of the Rapporteurs for the update of the EMA Guideline on Clinical Investigation of Medicinal Products in the Treatment of Diabetes Mellitus which has recently been adopted.
