Before joining Precision as Chief Medical Officer, Harpreet Singh, MD, served as Director of Oncology Division 2 at the FDA, where she played a pivotal role in advancing oncology drug development strategies. Dr. Singh has extensively published on dose optimization strategies and oncology clinical trial design, with a focus on balancing efficacy, tolerability, and patient-centered outcomes.
How Project Optimus became an FDA priority
In 2021, the FDA launched Project Optimus, a transformative initiative aimed at reshaping how oncology drugs are dosed.1 For years, traditional oncology drug development relied heavily on the maximum tolerated dose (MTD) approach—a strategy that worked well for chemotherapy but has proven less effective for newer, targeted therapies. Now, the FDA's Oncology Center of Excellence is pushing the industry to prioritize patient safety and therapeutic precision with a revamped dose optimization framework.
For pharmaceutical and biotech leaders, understanding Project Optimus is not just about regulatory compliance—it’s about ensuring your oncology drugs have the right balance of efficacy and tolerability, a critical factor for market success and patient outcomes.
This article looks at the objectives, implications, and opportunities presented by Project Optimus and demonstrates how partnering with a knowledgeable CRO like Precision for Medicine can help you navigate these requirements.
What is FDA's Project Optimus?
Project Optimus, spearheaded by the FDA’s Oncology Center of Excellence, aims to modernize dose selection and optimization in oncology drug development. Traditionally, dose selection focused on finding the MTD, often without considering whether this dose provided the best therapeutic balance. This approach, rooted in the era of cytotoxic chemotherapies, often led to unnecessary toxicity in patients taking modern targeted therapies or immunotherapies.
Project Optimus reflects a broader regulatory evolution towards more effective and patient-centered approaches in drug evaluation, aligning with advancements in scientific understanding and real-world needs in oncology.2 The project promotes the use of innovative science and technology in drug development, emphasizing adaptive clinical trial designs and utilizing real-world data to inform regulatory decision-making.
Key objectives of Project Optimus
-
Reforming Dose Selection Practices: The core goal is to identify doses that maximize both efficacy and safety—not just the highest dose patients can tolerate. This shift ensures that patients receive the optimal therapeutic dose that enhances outcomes while minimizing adverse effects.
-
Promoting Early Dose Optimization: By encouraging randomized evaluations of multiple doses early in clinical trials, Project Optimus aims to determine the best dose before pivotal Phase III trials, potentially reducing dose-related post-market challenges.
-
Enhancing Collaboration and Education: The FDA encourages drug developers to engage early with regulatory authorities. Discussions about dose-finding strategies before the start of pivotal trials are now a critical expectation under Project Optimus. The Good Clinical Practice (GCP) Inspection Collaboration with international regulators, such as the European Medicines Agency (EMA) and Japan's Pharmaceuticals and Medical Devices Agency (PMDA), also supports optimizing regulatory oversight in clinical trials.
-
Patient-Centric Dosing: Incorporating patient-reported outcomes (PROs) is a vital component of the initiative. Understanding how different doses affect quality of life, tolerability, and real-world patient experiences is key to optimizing treatment. However, controversies surrounding the subjective nature of PROs have raised questions about their reliability in clinical trials, highlighting ethical considerations of patient safety and the importance of transparent data collection.3
Impact on clinical trial design
Project Optimus is transforming how dose-finding studies are conducted. Companies are now expected to move away from the MTD-centric approach to a more nuanced strategy that explores a broader range of doses.
-
Broader Dose Exploration: Instead of a narrow focus on the highest tolerable dose, Project Optimus encourages exploration of a range of doses, including lower doses that might be equally effective but less toxic.
-
Randomized Dose-Ranging Studies: Early clinical trials are now expected to include randomized dose-ranging studies, aiming to identify the optimal therapeutic window before advancing to later phases.
-
Integration of PK and PD Data: Pharmacokinetic (PK) and pharmacodynamic (PD) data are crucial for understanding how different doses interact with the body and affect cancer cells. Optimus emphasizes the importance of using this data to make informed dosing decisions.2
The FDA has issued guidance documents outlining compliance requirements under Project Optimus, emphasizing the integration of PK, PD, and PRO data into clinical trial designs to ensure robust dose optimization.2 Additionally, adaptive clinical trials, which allow for modifications based on emerging data, are encouraged to enhance flexibility and responsiveness in study methodologies.
Challenges and opportunities for pharma and biotech
-
Operational Complexity: Designing trials to evaluate multiple doses is more complex and resource-intensive. Companies must now develop studies that assess multiple doses, PK, and PD data simultaneously, complicating trial execution.2
-
Increased Costs: Expanding early-phase trials to include multiple doses can lead to higher initial costs. However, this investment may ultimately reduce costs related to addressing safety issues or dose adjustments post-approval. Despite its potential benefits, some companies have expressed concerns about increased development costs and the complexities associated with meeting new FDA guidelines, which could hinder the drug approval process and impact financial sustainability, especially for smaller biotech firms.
-
Competitive Advantage: Companies that succeed in early dose optimization may differentiate their therapies in a crowded market by offering better safety profiles and patient outcomes.
-
Patient-Centric Benefits: By focusing on tolerability and quality of life, developers can build stronger relationships with patients and healthcare providers, enhancing the overall perception of their therapies. Engaging patients in trial design also assists in aligning study objectives with patient needs, which is crucial for improving adherence and achieving meaningful outcomes.
