Millikan IHO Week 2 Flashcards
Human Oncology Trials: Phase 1 Goals
to define a dose (and schedule) tolerable for human patients and ‘optimized’ by some criteria for toxicity and/or efficacy
Human Oncology Trials: Phase 2 Goals
to define an anti-cancer effect in some defined group of patients-a ‘disease state’ (hypothesis generating)
Human Oncology Trials: Phase 3 Goals
to formally compare some ‘novel’ treatment (or therapeutic strategy) with an existing standard (hypothesis testing)
how the body affects the drug
pharmacokinetics
how the drug affects the body
pharmacodynamics
Phase 1 Clinical Trials
aims to define ‘dose limiting toxicity’ for a particular schedule of 1 or more agents; typically less than 40 patients
Toxicity of Events: Grade 1
No physiologic or clinical consquence
Toxicity of Events: Grade 2
Physiologically Relevant
Toxicity of Events: Grade 3
Events are potentially associated with major morbidity (hospitalization, intensive treatment, etc)
Toxicity of Events: Grade 4
Events are life threatening
Phase 2 Clinical Trials
Scientific and statistical goal is to define the rate of ‘benefit’ in a defined population; uses a quick response marker, 30-60 patients; includes available info about prognostic factors
What do the following have in common: low albumin, high ferritin, high platelets, elevated crp, esr, elevated beta 2 microglubulin, elevated IL6, age, particular genetic lesions
Prognostic Factors
Phase 3 Clinical Trials
scientific and statistical goal to formally compare 2 or more tx or strategies using a definitive end-point such as survival time; 300-1200 patients; needs to be pass ‘lucky you’ ethical test
