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.

High Consistency between Regulatory Decisions for New Drugs between the Swiss Swissmedic, the European Medicines Agency and the United States Food and Drug Administration

Ulrich P Rohr, Anita Wolfer, Christine Haenggeli

SMC regulatory decisions on New Active Substance (NAS) drug approvals were compared with the FDA and EMA decisions, focusing the analysis on the same drugs and data sets, with particular focus on the oncology products, this over a 10-year-period between Jan 1st 2009 and Dec 31st, 2018. In summary, we were able to show that for the investigated 10-year time period the decision making between SMC, EMA and FDA was highly consistent and independent of therapeutic area with a consensus decision rate of 84% for non-Oncology products and 88% for Oncology Products.

A decade comparison of regulatory decision patterns for oncology products to all other non-oncology products among Swissmedic, European Medicines Agency, and US Food and Drug Administration

Ulrich-Peter Rohr, Mario Iovino, Leonie Rudofsky, Qiyu Li, Stephanie Juritz, Arunas Gircys, Oliver Wildner, Magda Bujar, Claus Bolte, Simon Dalla Torre di Sanguinetto, Anita Wolfer

Consensus of regulatory decisions on the same Marketing Authorization Application (MAA) are critical for stakeholders. In this context, regulatory decision patterns from Swissmedic, the US-FDA and the European Medicines Agency (EMA) were analyzed for hemato-oncology products (OP) and non-oncology products (NOP). High concordance in regulatory decisions was observed between agencies for OP as well as NOP.  The main clinical driver for divergent decisions for OP was nonrandomized trial design and low patient numbers.

This article provides a summary of discussions from the American Statistical Association (ASA) Biopharmaceutical (BIOP) Section Open Forum organized by the ASA BIOP Statistical Methods in Oncology Scientific Working Group in coordination with the US FDA Oncology Center of Excellence and LUNGevity Foundation on January 14, 2021, and February 8, 2021. Diverse stakeholders including oncologists, patient advocates, experts from international regulatory agencies, academicians, and representatives of the pharmaceutical industry engaged in a discussion on how best to incorporate lessons learned during the COVID-19 pandemic into the design of future oncology trials. While recognizing that decentralized or hybrid cancer trials may increase variability associated with measurement error and potentially increase bias in treatment effect estimation, panel discussions highlighted the importance of flexibility for decreasing patient burden, which has the potential to increase access to and retention in cancer clinical trials and may broaden the representation of real-world patients in the trial setting.

The article provides a summary of discussions from the American Statistical Association (ASA) Biopharmaceutical (BIOP) Section Open Forums on March 18th, June 10th, and July 8th of 2021, organized by the ASA BIOP Statistical Methods in Oncology Scientific Working Group in coordination with the U.S. Food and Drug Administration (FDA) Oncology Center of Excellence and the LUNGevity Foundation. Diverse stakeholders including oncologists, patient advocates, experts from regulatory agencies across the world, academicians, and representatives from the pharmaceutical industry engaged in a lively discussion on strategies for and designs of dose-optimization studies in cancer drug development. Dose-optimization is one of the major challenges in oncology drug development. The discussions were focused on considerations in designing dose-optimization studies of products for treatment of cancer patients in pre-approval and post-approval stages. Presenters and panelists discussed diverse ideas and methods and agreed that a shift in paradigm is required in oncology drug development that should improve dose optimization while not unnecessarily delaying patient access to potentially efficacious new treatments.

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.

Simon Dalla Torre Di Sanguinetto, Esa Heinonen, Janine Antonov, Claus Bolte 

Comparison study of Swissmedic's (SMC's) regulatory marketing authorization decisions to those of the US Food and Drug Administration (FDA) and European drug regulatory authorities (EU). The three authorities adhere largely to the same scientific principles and regulatory guidelines; therefore, remaining disparities ought to be considered in a cultural, legal and public health priority context.
