• More than one-third of adverse events in drug labels are symptoms (nausea, fatigue, sensory neuropathy)
• In clinical trials, adverse symptom information is reported by research staff, not directly by patients
• Health professionals underestimate incidence and severity of symptoms vs. patients’ own accounts
• Staff-based adverse symptom assessments occur at clinic visits, missing remote between-visit events
Background
• In oncology, standard instrument for AE reporting is CTCAE
–Item bank of ~1000 AE items–Magnitude graded on ordinal scale–Created by consensus, never validated–About 10% of items are symptoms
• Purpose is adverse event screening, not endpoint evaluation
CTCAE
• 10/08: NCI issued contract to create PRO-CTCAE• Item development: complete
– Identified 77 CTCAE items amenable to PRO• Subset of “Core” symptoms
–Drafted patient terms (sensory neuropathy = numbness and tingling)–Determined “attributes” of symptoms to be assessed
• Presence, frequency, severity, interference, amount
–Determined response option scales (verbal descriptors)–Selected default recall period (7-day)
• Cognitive interviews: in progress• Web administration platform: v1 complete• Current study to assess measurement properties of items
PRO-CTCAE Development
• To assess measurement properties of newly developed PRO-CTCAE items
–Validity–Reliability–Sensitivity–Recall period
• Purpose of items is adverse event screening, not granular assessment of symptoms as clinical trial endpoints
• N=400 to be accrued at 5 sites–Mayo, Memorial Sloan-Kettering, MD Anderson, Duke, Dana-

Objective of this Study
Types of PRO-CTCAE Items• PRESENT/NOT PRESENT (18 symptoms):
– In the last 7 days, did you have any ______ (e.g., unusual darkening of the skin):– ○ Yes ○ No
• FREQUENCY (24 symptoms):– In the last 7 days, how OFTEN did you have ______ (e.g., vomiting):– ○ Never ○ Rarely ○ Occasionally ○ Frequently ○ Almost Constantly
• SEVERITY (53 symptoms):– In the last 7 days, what was the SEVERITY of your ______ (e.g., pain) at its worst:– ○ None ○ Mild ○ Moderate ○ Severe ○ Very severe
• INTERFERENCE (20 symptoms):– In the last 7 days, how much did ______ (e.g., fatigue, tiredness, or lack of energy)
INTERFERE with your (daily activities):– ○ Not at all ○ A little bit ○ Somewhat ○ Quite a bit ○ Very much
• AMOUNT (2 symptoms):– In the last 7 days, did you have any ______ (e.g., hair loss):– ○ Not at all ○ A little bit ○ Somewhat ○ Quite a bit ○ Very much
Types of PRO-CTCAE Items (con’d)
• Number of items per symptom varies from 1 to 3– Pain has 3 items (frequency, severity, and interference)– Shortness of breath has 2 items (severity and interference) – Insomnia has 1 item (severity)
• Total: 77 symptoms; 117 items• Items currently available in English
– Future plan to translate/validate in other languages
PRO-CTCAE Web Interface
Study staff view: Custom forms can be created per study by selecting from available symptoms.
PRO-CTCAE Web Interface
Patient view: When a patient logs in, forms which need completing are displayed.
PRO-CTCAE Web Interface
Patient view: For a symptom with multiple items, if “Never” or “None” is selected for the first item, the remaining items are not displayed.
PRO-CTCAE Web Interface
Patient view: Additional items are displayed because “Occasionally” is selected for the first item.
Eligibility (Inclusions)• ≥18 years of age• Disease and treatment matching 1 of the 6 following cohorts:
– Adjuvant breast: initiating adjuvant chemotherapy within the next 7 days or already receiving adjuvant chemotherapy within the first cycle of treatment

• Patient is expected to return to clinic in 1-6 weeks• Patient can be reached at a single telephone number (daily phone call portion
only)• Able to complete web and paper questionnaires in English by themselves or with

Statistics / Power• Primary: Assess validity of each PRO-CTCAE item
– Compare each item between patients with ECOG PS 0-1 vs 2-4 at the Visit 1 time point using t-tests
– Adjust for multiplicity using Hochberg’s step-up method– Power
• Core items: 99% for large effect size, 63-91% for moderate effect size• Non-core items: 49-99% for large effect size, 9-65% for moderate effect
size• Other planned analyses:
– Assess the test-retest reliability of selected PRO-CTCAE items– Assess the responsiveness (sensitivity to change) and clinical
significance of each PRO-CTCAE item– Investigate cut-points for notification of severe PRO-CTCAE symptoms– Compare clinician- and patient-reported CTCAE items– Compare daily, 7-day, 2-week, 3-week, and 4-week recall periods– Explore construction of an overall grade for symptoms with multiple
items
