Seasonal affective disorder (SAD), also known as major depressive disorder with a seasonal pattern, is a condition of regularly recurring depressive episodes that most commonly occur in autumn and winter and remit during spring and summer. Despite the relatively high prevalence and morbidity of SAD, this disorder still often goes undiagnosed, in large part because health care professionals do not generally consider a potential seasonal pattern in a patient who presents with depression.

Since the introduction of estimands, the answer to “Why are estimands necessary?” has remained constant – to allow for clearer communication about benefits/risks of a potential treatment to the relevant stakeholders. However, as illustrated in this blog, the number of questions as to how & when to use them has grown considerably.

Analyses conducted using the overall population can mask the extent of the benefit-risk in subgroups of patients.  Thus, subgroup analyses are critical to fully understand the benefit-risk in pivotal oncology trials and guide regulatory decisions for approval and labelling.  However, subgroup analyses also present several challenges especially for overall survival (OS) where larger sample sizes and longer follow-up are needed, and where early analyses of immature data may be conducted.

Real-World Data (RWD) is being increasingly utilized in clinical research to help support drug approvals. The U.S. Food and Drug Administration (FDA) guidance on Considerations for the Use of Real-World Data and Real-World Evidence (RWE) to Support Regulatory Decision-Making for Drug and Biological Products provides thoughtful recommendations on the use of RWE to support approval of a new indication for marketed drugs. This guidance is part of the FDAs Real-World Evidence Program which provides additional guidance for the use of RWE to support regulatory decisions.

Interim analyses (IA) are an essential part of clinical trials that—as a form of adaptive design—can help sponsors make informed decisions about whether to keep a trial going or discontinue it entirely. Join Rho’s Brett Gordon, Ben Vaughn, and Scott Mollan for this Q&A roundtable that will cover some of the most frequently asked questions they get from pharma companies about interim analysis.

How do we get both information to rule out harm and assess the overall survival benefit, while still being realistic in our conduct of oncology clinical trials? The answer to that question, depends on a variety of factors, such as the type and aggressiveness of the cancer. As you are designing your next clinical trial assessing OS, we have listed some items to keep in mind.

Overall survival (OS) is an endpoint of significant importance when assessing safety and efficacy in oncology studies. Multiple trial design decisions are made when planning the analysis of OS and analysis of OS is even more complicated when it is analyzed as a non-primary endpoint. Here are some common trial design elements to consider that may have potential pitfalls for your next study.

When analyzing overall survival in a post-hoc manner sponsors need to carefully consider the types of analyses to present and have a thorough understanding of both the regulatory precedent and market landscape which their product will enter.

If you were born during the Spanish flu of 1918, you had a 2-3x higher risk of Parkinson’s. If COVID-19 caused the same viral damage, what does that mean for all of us? In this webinar, study author Pete Schmidt, PhD (Rho) and Mark Stacy,

Overall survival (OS) is both an important efficacy & safety endpoint for oncology trials. Often when study results are submitted for regulatory consideration, OS results are often “immature”/still in their early stages which makes them difficult to evaluate. Understanding how to place these results into a proper benefit-risk framework for consideration is therefore important when assessing a potential treatment’s viability.
