The clinical research process is an integral part of the biopharmaceutical and high risk medical device product development process. This Case Study illustrates an example for why a long-utilized research study design may not be appropriate to support the marketing approval for all such products. The case also illustrates how the aforementioned research study design may potentially be improved through the use of additional statistical techniques. The Assignment questions for this Case Study write-up require you to explain the critical components of the case from a situational perspective, as well as to develop replies to specific questions presented by the case.

Introduction:
As a medical professor responsible for creating assignments and providing feedback to medical students, I understand the importance of clinical research in the biopharmaceutical and high risk medical device product development process. This case study provides an opportunity for students to examine the limitations of traditional randomized controlled trials (RCTs) and explore the benefits of adaptive platform trials. The questions asked in the case study require students to analyze the critical components of the study and anticipate potential challenges concerning the GBM AGILE trial.
1. In 2-3 paragraphs please present a situational description of the case that addresses: Who is Dr. Brian Alexander? What types of patients does he treat? Why is he working with GBM AGILE?
Dr. Brian Alexander is a neuro-oncologist at the Dana-Farber Cancer Institute in Boston. His primary focus is treating patients with glioblastoma (GBM), a severe form of cancer that develops in the brain. Dr. Alexander is working with the GBM Adaptive Global Innovative Learning Environment (GBM AGILE) to develop an innovative clinical trial that uses adaptive platform techniques to facilitate the development of new and effective treatments for patients with GBM. This trial seeks to challenge traditional clinical trial designs by allowing researchers to test multiple treatments simultaneously and adapt the study based on real-time results.
2. What are the distinguishing features of traditional randomized controlled trials (RCTs)? What are the advantages and disadvantages of traditional RCTs versus other clinical trial designs? Why have RCTs been widely considered to be the ‘gold standard’ for clinical research for the past few decades?
Traditional RCTs are designed to test a single intervention or therapy against a control group. The main advantage of RCTs is that they minimize bias and control extraneous variables, which enhances the validity and reliability of the study outcomes. However, RCTs are time-intensive, expensive, and can only test one therapy at a time. This limitation makes it challenging to conduct trials of rare diseases or conditions. Additionally, RCTs require a large sample size to achieve statistical power, which may limit participation or introduce selection bias. Despite these challenges, RCTs are considered the ‘gold standard’ for clinical research because of their superior control of confounding factors and ability to provide high-quality evidence of efficacy.
3. What are the primary ways in which an adaptive platform trial differs from an RCT? What are the statistical considerations?
Adaptive platform trials differ from RCTs in that they allow for multiple interventions to be tested simultaneously, and the study is modified based on real-time data analysis. This approach enables clinical researchers to design more efficient and flexible trials. The key statistical considerations for adaptive platform trials include minimizing type 1 and type 2 errors, controlling the overall alpha level, and determining the appropriate sample size for each intervention arm in the trial. Additionally, because the trial is continually modified based on data analysis, the study’s design and sample size may need to be updated, which can be challenging.
4. What do you anticipate will be the biggest challenge for Dr. Alexander and his colleagues as they launch the GBM AGILE trial? If you believe that there will be multiple major challenges, please prioritize your answers.
The most significant challenge that Dr. Alexander and his colleagues might face during the GBM AGILE trial launch is managing the complexity of the adaptive platform design. This requires constant attention and revision, which can quickly become time and resource-intensive. Another significant challenge they may face is balancing the need for flexibility with data integrity. Adaptive platform designs are meant to be changed based on real-time analysis, but this can create issues with blinding among trial participants, leading to biased results. Lastly, recruiting sites worldwide, maintaining tracking systems, and achieving regulatory compliance requirements for the trial could also present challenges.
5. What business models for the Global Coalition for Adaptive Research (GCAR) do you believe are the most promising and why?
GCAR has several business models that could prove promising, depending on their goals. For example, their non-profit model allows for greater access to GBM AGILE without financial barriers for participants. Alternatively, a for-profit model could provide incentives for pharmaceutical companies to participate in the trial with added potential profits. Finally, partnerships with government research and funding bodies to supplement financing goals and mandate global relevance could ensure optimal trial participation and evidence-based results. Ultimately, the chosen model should provide sustainability and independence to GCAR’s governance, have adequate funding to support the necessary resources, allow for flexible organizational structure, and establish clear goals to align with stakeholders.
