👥Biography 个人简介

Jordi Rodon Ahnert, MD, PhD is Associate Professor in the Department of Investigational Cancer Therapeutics at MD Anderson Cancer Center, where he co-directs the Clinical-Translational Research Platform. Before joining MD Anderson, Dr. Rodon was a founding leader of the Phase I Clinical Trials Program at the Vall d'Hebron Institute of Oncology (VHIO) in Barcelona — one of the most internationally recognized European early-phase oncology programs — where he built an outstanding infrastructure combining phase I clinical trials with deep translational biomarker science. Dr. Rodon is internationally recognized for his expertise in PI3K pathway inhibitor development and adaptive trial design methodology. He has led first-in-human and dose-escalation studies of multiple PI3K, AKT, and mTOR inhibitors, contributed extensively to the clinical pharmacology characterization of these agents, and helped define the biomarker frameworks used in PI3K inhibitor patient selection. Beyond PI3K, Dr. Rodon is one of the leading advocates for adaptive platform trial designs in early-phase oncology, having co-designed and analyzed multiple Bayesian adaptive dose-escalation and expansion trials that have reduced sample size requirements and accelerated recommended phase II dose identification. He is also recognized for his work translating preclinical models — particularly patient-derived xenografts (PDX) and co-clinical trial frameworks — into phase I trial hypotheses, exemplifying a rigorous bench-to-bedside approach to drug development. Dr. Rodon has authored over 250 peer-reviewed publications and co-chaired the ESMO/AACR symposium on early drug development.

🎓Key Contributions 主要贡献

PI3K/AKT/mTOR Inhibitor Phase I Development — Clinical Pharmacology and Biomarkers

Led first-in-human and early-phase studies of multiple PI3K pathway inhibitors, including the pan-PI3K inhibitor copanlisib, the dual PI3K/mTOR inhibitor gedatolisib (PF-05212384), and the AKT inhibitor capivasertib (AZD5363). Contributed rigorous pharmacokinetic/pharmacodynamic characterization of each agent — including hyperglycemia kinetics for PI3K inhibitors, tumor pAKT and pS6K1 suppression from serial biopsies, and the relevance of PTEN loss versus PIK3CA mutation in predicting differential sensitivity — establishing these correlatives as the standard pharmacodynamic evidence package for PI3K pathway phase I trials.

Adaptive Trial Design for Early-Phase Oncology

Championed the adoption of Bayesian adaptive dose-escalation designs — including BOIN, keyboard design, and i3+3 — and seamless phase I/II adaptive expansion frameworks in the VHIO and MD Anderson phase I programs. Co-authored influential publications demonstrating through simulation and retrospective comparative analyses that adaptive designs reduce the number of patients treated at sub-therapeutic or overtly toxic doses, decrease time to recommended phase II dose identification by 20–30%, and permit biomarker-adaptive cohort selection during expansion — influencing regulatory guidance on adaptive early-phase trial design from both FDA and EMA.

Co-Clinical and PDX-Informed Phase I Translation

Developed and applied a "co-clinical trial" framework at VHIO in which patient-derived xenograft (PDX) models were established from phase I trial patient biopsies and treated in parallel with the clinical study — enabling prospective mechanistic understanding of response and resistance in individual patients. Demonstrated that PDX pharmacodynamic responses (pAKT suppression, proliferation index) correlate with matched patient tumor biopsy changes and clinical outcomes, establishing PDX co-clinical trials as a valid translational tool for phase I biomarker hypothesis testing and resistance mechanism discovery.

VHIO Phase I Program Architecture — European Early-Phase Oncology Model

Co-founded and helped build the VHIO Phase I Clinical Trials Program in Barcelona from its inception, establishing VHIO as one of Europe's leading early-drug-development centers. Developed the institutional infrastructure for mandatory molecular pre-screening, paired tumor biopsies, pharmacokinetic sampling, and ctDNA monitoring. VHIO's phase I program under Dr. Rodon's leadership became a reference center for multiple global first-in-human trials across oncology companies, demonstrating the viability of a European academic center as a global phase I hub and influencing similar program development across Spain, France, and the UK.
