RR Herring Distinguished Professor of Medicine Center Medical Director, Sarcoma Center Deputy Chairman, Dept. of Sarcoma Medical Oncology Clinical Trials in STS Texas Medical Center Houston, Texas

2 What are Clinical trials?
Research investigations (experiments) designed meticulously to find “new agents” or “improve upon the current SOC” (dose, schedule, toxicities, relapse rate/time, survival, QOL…) “Phases” of drug development Preclinical – Drug screens, PDX, animal model Objective: Determine LD10 Clinical – Phase 1-4 (Human) Clinical Trials

3 Phase 1 trials Typically not cancer specific (exceptions e.g. targeted therapies), ~ patients Primary Objective is to determine the appropriate dose and schedule for humans (MTD, OBD) But, also provides some signal of efficacy in specific subsets

4 Phase 2 trials Typically VERY cancer specific (exceptions e.g. targeted therapies like NTRKi), ~ patients in a single-arm trial Primary Objective is to determine the efficacy and safety in humans Endpoints: Response rate, Clinical Benefit Rate, Progression-free survival Toxicities / side-effects

5 Phase 3 trials Typically randomized, VERY cancer specific, several hundred patients Primary Objective is to compare the efficacy and safety between new Rx and current SOC Endpoints: Survival, Progression-free survival, Response rate, QOL If indeed superior, new drug/regimen gets FDA approval for commercial use

6 Phase 4 trials Rarely mandated post marketing by FDA to collect more “real world experience” with side-effects/toxicity profile of the newly approved drug/regimen

7 How do I find out about Clinical trials in sarcomas
Seek consultation with a Sarcoma expert and ask him/her to guide you Appropriateness of a trial vs. SOC (E,T,C) Clinicaltrials.gov Foundations, Advocacy and Support Groups Websites of major cancer centers
