Abstract:
The efficacy of targeted therapies in patient populations selected for treatment on the basis of the molecular features of their tumours is shifting the current focus of treatment to biomarker-driven clinical trials. Phase I trials provide an arena for early hypothesis testing, examining not only safety and toxicity, but also target engagement, biologically effective dosages, and the appropriate patient population. In this Perspectives article, we describe this new trend in early drug development, establishing the different approaches for building a pre-screening programme in an academic institution that is involved in early drug development. Our experience establishing the phase I programme at Vall d'Hebrón serves as an example of how these approaches can be integrated in ongoing trials, and we believe these considerations will help others to implement similar programmes in their institutions.
Insights
Biomarker-driven clinical trials are the future of cancer treatment, focusing on targeted therapies. This approach optimizes early drug development by testing safety, dosage, and patient selection in phase I trials.
Area of Science:
- Oncology
- Clinical Pharmacology
- Translational Medicine
Background:
- The paradigm of cancer treatment is shifting towards targeted therapies, necessitating patient selection based on molecular tumor characteristics.
- Biomarker-driven clinical trials are crucial for evaluating the efficacy and safety of these novel therapeutics.
Approach:
- This perspective outlines strategies for establishing pre-screening programs within academic institutions to support early-phase drug development.
- It details the integration of these programs into ongoing clinical trials, using the Vall d'Hebrón phase I program as a case study.
Key Points:
- Phase I trials are essential for early hypothesis testing, assessing safety, toxicity, target engagement, and optimal biological effective doses.
- Identifying the appropriate patient population is a critical component of biomarker-driven trial design.
- Academic institutions play a vital role in building the infrastructure for early drug development and biomarker discovery.
Conclusions:
- Implementing robust pre-screening programs in academic settings can facilitate biomarker-driven clinical trials.
- This approach enhances the efficiency of early drug development and supports the personalized medicine revolution in oncology.
- The insights provided aim to guide other institutions in establishing similar early drug development programs.
