Regulatory Challenges: Is a Surrogate End Point Instead of Overall Survival Enough for Regulatory Approval of (Neo)Adjuvant Cancer Treatment? The Swissmedic Perspective

Matea Pavic, Anita Wolfer, Qiyu Li, Arunas Gircys, Stephanie Juritz, Andreas Wicki, Thomas Cerny, Ulrich-Peter Rohr

From a regulator's point of view, a market authorization can only be granted with a positive benefit-risk (BR) balance. Divergent clinical positions of the US-FDA and the European Medicines Agency (EMA) on surrogate end points initiated this commentary from a Swiss regulator's point of view. In collaboration with oncologists from the Swiss Human Medicines Expert Committee, Swissmedic presents and discusses relevant elements of our current regulatory decision making for (neo)adjuvant oncology drugs.

Tendler, Marc Theoret, and Richard Pazdur

This article provides a summary of discussions from the American Statistical Association (ASA) Biopharmaceutical (BIOP) Section Open Forum on April 8, 2021, and May 13, 2021, organized by the ASA BIOP Statistical Methods in Oncology Scientific Working Group in coordination with the United States Food and Drug Administration (U.S. FDA) Oncology Center of Excellence (OCE) and LUNGevity Foundation. In most cancer trials, disproportionately low numbers of older adults and certain racial minority groups are enrolled, even though a high incidence of cancer is observed in these subpopulations. This results in a lack of sufficient information on efficacy and safety of new treatments in such demographic subpopulations.

Discussions with a diverse group of stakeholders including oncologists, patient advocates, experts from international regulatory agencies, academicians, and representatives of the pharmaceutical industry focused on designing future pre- and post-market studies to evaluate treatment effect in demographically underrepresented (UR) cancer populations such as racial and ethnic minority groups and older adults. It is noted that often there is poor or no representation of pediatric cancer patients as well. However, not all adult cancers are observed in pediatric patients and vice-a-versa and these discussions mainly focused on adult cancers. It is recognized that inclusion of broader patient populations can introduce heterogeneity and if the trial includes patients with more comorbidities or poorer prognosis may increase the chances of rejecting an effective therapy. However, there are clinical trial designs and statistical methods to include and evaluate treatment effects in UR cancer patients. Importantly, a commitment and a concerted effort from all stakeholders to change the current practice is necessary to better understand the benefit/risk in these demographically UR patients in cancer clinical trials.

Use of Nonconcurrent Common Control in Master Protocols in Oncology Trials: Report of an American Statistical Association Biopharmaceutical Section Open Forum Discussion

Rajeshwari Sridhara, Olga Marchenko, Qi Jiang, Richard Pazdur, Martin Posch, Scott Berry, Marc Theoret, Yuan Li Shen, Thomas Gwise, Lorenzo Hess, Andrew Raven, Khadija Rantell, Kit Roes, Richard Simon, Mary Redman, Yuan Ji, and Cindy Lu

This article summarizes the discussions from the American Statistical Association (ASA) Biopharmaceutical (BIOP) Section Open Forum that took place on December 10, 2020 and was organized by the ASA BIOP Statistical Methods in Oncology Scientific Working Group, in coordination with the U.S. FDA Oncology Center of Excellence. Diverse stakeholders including experts from international regulatory agencies, academicians, and representatives of the pharmaceutical industry engaged in a discussion on the use of nonconcurrent control in Master Protocols for oncology trials. While the use of nonconcurrent control with the concurrent control may increase the power of detecting the therapeutic difference between a treatment and the control, the panelists had diverse opinion on the statistical approaches for modeling nonconcurrent and concurrent controls. Some were more concerned about the temporality of the nonconcurrent control and bias introduced by different confounders related to time, for example, changes in standard of care, changes in patient population, changes in recruiting strategies, changes in assessment of endpoints. Nevertheless, in some situations such as when the recruitment is extremely challenging for a rare disease, the panelists concluded that the use of a nonconcurrent control can be justified.
