About Project Optimus
FDA’s Project Optimus is reshaping oncology drug development by focusing on dose optimisation, with an emphasis on identifying the optimal biological dose (OBD) rather than the traditional approach of determining the maximum tolerated dose (MTD). This shift addresses the need for a better balance between efficacy, safety, and tolerability, aiming to reduce the significant toxicity associated with previous dosing strategies. Traditional Phase 1 trials often led to unnecessary side effects and poor patient quality of life due to the high doses used to maximize tumor response. Project Optimus, in contrast, mandates early-phase dose-ranging studies to identify dosing that provides the greatest benefit with fewer risks.
The concept of precision medicine plays a significant role in this shift, as it tailors treatment based on individual genetic and molecular characteristics of patients. By focusing on the biomarkers that guide therapy selection, clinical trials can be designed to ensure that therapies are administered to the right patients. For therapies that do not have a known biomarker, early-phase exploration, adaptive trial designs, and tissue sampling are strategies that can uncover useful data and refine future studies. Basket trials, for example, allow the evaluation of a single therapy across different cancer types with a common genetic characteristic, streamlining the process and increasing study efficiency.
Adaptive trial designs are particularly important in this context, as they allow researchers to adjust patient recruitment in real-time based on interim data, which is critical in oncology trials where understanding of biomarkers evolves over time. Bayesian statistics are frequently employed in these adaptive designs to provide flexibility and continuously refine patient selection. This approach offers a more targeted understanding of drug efficacy while ensuring patient safety, but requires precise planning and decision-making criteria to be effective.
Collaboration with contract research organisations (CROs) is essential for pharmaceutical and biotech companies to successfully navigate Project Optimus’s requirements. CROs can offer valuable expertise in dose optimisation, regulatory alignment, and trial design. With their experience, CROs help developers design early-phase trials that effectively explore the dose-response relationship and ensure compliance with FDA and EMA guidelines. Additionally, they use advanced data modelling techniques to analyze complex dose-response data, delivering insights that can refine dosing regimens and improve patient outcomes.
About Precision Medicine
Precision medicine is transforming oncology by providing personalized therapies based on a patient’s genetic and molecular profile, aiming to improve efficacy, reduce toxicity, and reshape clinical trial designs. Genetic factors, like mutations in tumor DNA (e.g., EGFR in lung cancer or HER2 in breast cancer) and genetic predispositions (e.g., BRCA in hereditary cancers), inform treatment and preventive strategies. Additionally, molecular markers such as protein expression and signaling pathways guide therapy choices, with advancements like next-generation sequencing enabling detailed tumor characterization.
Traditional oncology trials used a “one-size-fits-all” approach, but precision medicine focuses on biomarker-driven patient selection, enhancing treatment efficacy. In cases where biomarkers are not yet identified, early-phase trials, tissue sampling, and adaptive trial designs allow flexibility in identifying biomarkers during the study. Basket trials study therapies across multiple cancer types using common genetic markers, improving efficiency and accelerating timelines.
Adaptive trial designs using Bayesian statistics enable real-time adjustments based on interim data, refining patient selection and efficacy. Recruitment for small, focused cohorts can be challenging, requiring global collaboration. Real-world data (RWD) is increasingly important, offering insights into therapy efficacy and safety across diverse populations for regulatory submissions.
