    • Drug Development Process – Study Phases Classic Clinical Development Phase I Phase II Phase III Phase IV Tolerability Activity Efficacy Surveillance Approval FDA/EMEA/… Tinazzi A Cattaneo A Ferraresi L Ferroni P WEB-Triage: an applicaition for patient Registration in Phase I 4 dose-escalation studies PhUSE 2007, MT02 (Lisbon, Portugal – 8-10 October 2007)
    • Phase I Dose Escalation studies in Oncology Conducted in humans Conducted in cancer patients Usually with advanced disease Failing previous ‘standard’ therapies Good Performance Status Dose escalation Pre-defined dose-levels (Fibonacci series) The starting dose is usually 1/10 the median lethal dose in mouse or other animals (LD10) Maximum Tolerated Dose (MTD), the dose where 2/3 or 2/6 DLTs are experienced Recommended Dose (RD), the dose before MTD where no more than 1/6 DLTs are experienced Tinazzi A Cattaneo A Ferraresi L Ferroni P WEB-Triage: an applicaition for patient Registration in Phase I 5 dose-escalation studies PhUSE 2007, MT02 (Lisbon, Portugal – 8-10 October 2007)
    • Examples of Dose Limiting Toxicities (DLT) Drug Related Toxicities, such as Absolute granulocyte count <0.5 x10^9/L lasting >= 5 days Platelets <50 x10^9/L Failure to deliver therapy in day 8 due to drug related toxicity Tinazzi A Cattaneo A Ferraresi L Ferroni P WEB-Triage: an applicaition for patient Registration in Phase I 6 dose-escalation studies PhUSE 2007, MT02 (Lisbon, Portugal – 8-10 October 2007)
    • Example of a Dose Escalation Protocol Dose level Dose Dose (cohort) increment (mg/m2) 1 1 2 3 Starting dose 0.10 2 4 5 6 7 8 9 100% 0.20 3 10 11 12 17 18 19 RD 67% 0.33 4 13 14 15 16 17 … 50% 0.50 MTD 5 33% 0.67 6 33% 0.89 7 33% 1.18 8 33% 1.57 9 33% 2.08x1 x2 x3 Patient Cohort (patient nr. x1, x2, x3, …) Dose Limiting Toxicities Tinazzi A Cattaneo A Ferraresi L Ferroni P WEB-Triage: an applicaition for patient Registration in Phase I 7 dose-escalation studies PhUSE 2007, MT02 (Lisbon, Portugal – 8-10 October 2007)
    • Ethical Issues in Phase I in Oncology Maximising patients exposure to potentially therapeutic doses Minimising patients treated at ineffective doses Minimising patients treated at toxic doses Historically low probability of response in phase I trials Unknown toxicity and benefit of new agent Informed Consent Tinazzi A Cattaneo A Ferraresi L Ferroni P WEB-Triage: an applicaition for patient Registration in Phase I 8 dose-escalation studies PhUSE 2007, MT02 (Lisbon, Portugal – 8-10 October 2007)
    • Accrual Issues in Phase I in Oncology Better selection of patients Appropriate education of referring physicians Apply fewer restrictions in eligibility criteria The window of opportunity of starting a phase I trial may be limited because the clinical course of these end-stage patients is unpredictable No more than 2-3 investigator sites per trial Concurrent trials Tinazzi A Cattaneo A Ferraresi L Ferroni P WEB-Triage: an applicaition for patient Registration in Phase I 9 dose-escalation studies PhUSE 2007, MT02 (Lisbon, Portugal – 8-10 October 2007)
    • Patient TriageThe french word ‘triage’ means ‘picking out’ (sorting)and it was used in World War I, when a ‘system’ wasadopted for the sorting of wounded soldiers intospecific groups requiring differential medicalinterventions according to the severity of their injuries …a similar approach is used in emergency unit unit to ration limited medical resources and in Phase I studies in oncology…..In phase I trials, patients have to be selected as soonas possible so that investigators can be prepared totreat a new patient Tinazzi A Cattaneo A Ferraresi L Ferroni P WEB-Triage: an applicaition for patient Registration in Phase I 10 dose-escalation studies PhUSE 2007, MT02 (Lisbon, Portugal – 8-10 October 2007)
    • The Web-Triage Application: User Requirements Defining Study Characteristics Dose Levels Data to be Collected, including pre-registration data Library for Study items (i.e. chemotherapy regimens) Opening or Close dose-levels according to dose- escalation rules Manage concurrent dose-escalation trials The Investigators can review study status (dose-level cohorts) and propose candidates The Study Project Managers need to be alerted as soon as a candidate is proposed Review and approve|reject patient candidate Manage dose-levels (close, open and re-open) Tinazzi A Cattaneo A Ferraresi L Ferroni P WEB-Triage: an applicaition for patient Registration in Phase I 11 dose-escalation studies PhUSE 2007, MT02 (Lisbon, Portugal – 8-10 October 2007)
