CTEP Program Meeting Patient-Reported Outcomes (PROs) in Cancer Treatment Trials Ethan Basch, MD, MSc Memorial Sloan-Kettering Cancer Center PROs for Adverse Event Reporting March 18, 2008

Overview 1.Background 2.Rationale for using PROs for AE Reporting 3.Prior and ongoing research (outside scope of PRO-CTCAE contract) Questionnaire and platform development Feasibility Patient vs. clinician reporting

Essential activity in treatment trials To ensure patient safety To provide data about drug effects – Trialists, regulators, clinicians, patients Core activity in routine cancer care To guide therapy and supportive care Adverse Event Monitoring

Rationales for Patient-Reported Outcomes Approach to Adverse Symptom Reporting Improve efficiency of data collection – Eliminating data collection steps, reducing errors Provide more direct account of patient experience – Eliminating filtering of patient reports by others Engage patients as active participants in trials Enable real-time data capture (ePROs) – Automated alerts, between-visit reporting Provide subsequent patients with AE information reported by their peers, not clinical staff Harmonize CTCAE with current standards for symptom measurement using PROs – Eg, FDA guidance Trotti, Colevas, Setser, Basch: JCO, 2007

Research Prior to PRO-CTCAE Contract Created initial adaptations of CTCAE symptom items for pilot testing “STAR” items Basch: JCO, 2005

EXAMPLE: DIARRHEA Basch: JCO, 2005

Items Loaded to Web Platform Online interface –Patient self-reporting –Longitudinal report –Automated alerts Administration –Touchscreen kiosks and wireless tablet computers in clinic waiting areas –Home computers between visits Basch: J Am Med Informatics Assoc, 2007

Feasibility Studies Outpatients with lung, gynecologic, and genitourinary malignancies receiving chemotherapy Intervention: – Selected CTCAE symptoms – 10-minute training – Encouraged to login at follow-up visits – Access to website from home (voluntary) – Reports printed for clinicians at visits – Alerts  nurses for grades 3-4 Basch, JCO, 2007

Results Feasible Most patients are willing and able to self- report CTCAE symptoms at clinic visits – Including non-web avid, elderly, and end-stage with high symptom burdens – No attrition in login rates after up to 2 years or up to 40 clinic visits Basch, JCO, 2007

Satisfaction High patient satisfaction – Wish to continue using – Would recommend to others High clinician satisfaction – Accurate portrayal of patient status – Useful as basis for clinical decisions

57 alerts (25 different patients) 15 from clinic-based computers 42 from home computers Patient’s location 4 chemotherapy holds 7 tel contacts 3 med changes 3 appts made Clinician actions Basch, JCO, 2005 Toxicity Alerts for Grade 3-4 (n=80)

Conclusions Most patients receiving chemotherapy are willing and able to self-report adverse symptom information at clinic visits Clinicians find information valuable and will use it to guide treatment decisions

Real-World Question If PROs became a standard approach for reporting adverse symptoms in oncology, how might this alter the frequency or severity of documented toxicities? – Do patients report adverse symptoms differently from clinicians?

Patient vs. Clinician Reporting Paper survey 400 patient-clinician pairs – Cancer outpatient clinics Patients and clinicians answered the same CTCAE items Basch, Lancet Oncol, 2006

Comparison of Paired Observations

Cumulative Incidence of Symptoms Patient-reporting Clinician-reporting CTCAE Grade-2 (Moderate)CTCAE Grade-3 (Severe) Patient-reporting Clinician-reporting Basch, ASCO, 2008

Which Perspective Should Be Standard? Treatment trials/drug labeling – Choosing one approach vs. the other could impact how toxic drugs look on paper “Clinician knows best” TOXICITY “Patient knows best”

Which Perspective in Trials and Labels? If continue clinician reports as standard – Will appear to systematically under-report and under-rate severity of symptoms compared to patient reports If adopt patient reports as standard – Frequency and severity of AE reports on labels will likely increase Or report both? – Might they be reflecting different phenomena?

Longitudinal Study Design Patients and clinicians reported the same CTCAE symptoms at each clinic visit for up to 1.5 years Analyzed associations of patient vs. clinician CTCAE reports with risk of death, hospitalization, and daily health status Findings Clinician CTCAE symptom reporting predicts death and hospitalization, while patient reporting does not Patient CTCAE reporting correlates more highly with daily health status than clinician reporting Basch, ASCO, 2008

Conclusion Clinicians and patients provide complementary information – Capture different aspects of the experience with disease and treatment

Drug Labels Would inclusion of both patient-based and clinician-based adverse symptom data in drug labels cause confusion? – Instructive to look at examples of ratings reporting approaches outside of healthcare

Ongoing Research Multi-center cooperative group study (CALGB) – Feasibility of patient CTCAE reporting, nested in 5 treatment trials – Cancer centers/CCOPs PRO study nested in Phase II trial – Patients self-report CTCAE symptoms via computer – Clinicians review patient reports on computer, then agree or disagree/reassign grades – Clinicians assign attribution

CTCAE Patient Level Report (1)

CTCAE Patient Level Report (2)

Patients are willing and able to report CTCAE symptoms via computer Patient reporting is discrepant from clinician reporting – PROs more reflective of day-to-day experience Clinicians will accept patient-reported AEs for treatment decisions and documentation Reporting of both patient and clinician AE grades is reasonable in treatment trial results and labels – Would provide additional information about toxicity Summary

What are the barriers to widely implementing such a system? What AEs are appropriate for patient reporting? How should this work operationally? – Should clinicians use PROs to inform their own grades? – How often should patients self-report Only at visits? Between visits (eg, weekly)? Issues addressed in PRO-CTCAE contract Remaining Questions
