As new cancer treatment regimens demonstrate increased potential to improve patients’ survival, more focus is directed toward the quality of that extension of life and to obtaining additional information from patients regarding their experience with treatment. The utility of capturing patient-reported treatment-related symptoms to complement traditional clinician-rated symptomatic adverse event reporting is well-documented. The National Cancer Institute’s Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events is an item library aimed at capturing patient-reported symptoms to inform the patient perspective on a treatment’s tolerability. The U.S. Food and Drug Administration has recommended using the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events in clinical trials. A practical guideline is needed to inform a priori selection of specific Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events items for use in any given industry-sponsored oncology clinical trial. Standardizing this selection process will foster systematic and consistent data collection as part of drug development and enhance our knowledge on how to use patient-relevant information as part of a treatment’s risk/benefit assessment. This article presents methods and consensus recommendations for selecting specific Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events items to include in early-phase and late-phase oncology clinical trials.

Purpose The US National Cancer Institute (NCI) Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) was developed to enable patient reporting of symptomatic adverse events in oncology clinical research. This study was designed to assess the feasibility and resource requirements associated with implementing PRO-CTCAE in a multicenter trial. Methods Patients with locally advanced rectal cancer enrolled in the National Cancer Institute–sponsored North Central Cancer Treatment Group (Alliance) Preoperative Radiation or Selective Preoperative Radiation and Evaluation before Chemotherapy and Total Mesorectal Excision trial were asked to self-report 30 PRO-CTCAE items weekly from home during preoperative therapy, and every 6 months after surgery, via either the Web or an automated telephone system. If participants did not self-report within 3 days, a central coordinator called them to complete the items. Compliance was defined as the proportion of participants who completed PRO-CTCAE assessments at expected time points. Results The prespecified PRO-CTCAE analysis was conducted after the 500th patient completed the 6-month follow-up (median age, 56 years; 33% female; 12% nonwhite; 43% high school education or less; 5% Spanish speaking), across 165 sites. PRO-CTCAE was reported by participants at 4,491 of 4,882 expected preoperative time points (92.0% compliance), of which 3,771 (77.2%) were self-reported by participants and 720 (14.7%) were collected via central coordinator backup. Compliance at 6-month post-treatment follow-up was 333 of 468 (71.2%), with 122 (26.1%) via backup. Site research associates spent a median of 15 minutes on PRO-CTCAE work for each patient visit. Work by a central coordinator required a 50% time commitment. Conclusion Home-based reporting of PRO-CTCAE in a multicenter trial is feasible, with high patient compliance and low site administrative requirements. PRO-CTCAE data capture is improved through centralized backup calls.

e21704 Background: Patients with myeloproliferative neoplasms (MPN) have difficult symptom burden (i.e. fatigue, pruritus, night sweats) not resolved by current medical therapies including jak inhibitor therapy. We hypothesize that on-line (at home) yoga might alleviate MPN symptoms and complement medical therapy. Methods: MPN patients, recruited by social media, were asked to complete 60 min/week of online yoga (designed for MPN patients) for 12 weeks and completed online self-report surveys (weeks 0,7,12 and 16) on participation (Qualtrics), disease features, and symptom burden (MPN Symptom Assessment Form; NIH PROMIS measures of pain, anxiety, depression, sleep, and sexual function). Results: Two hundred and forty-four MPN patients completed the eligibility survey, 134 were eligible, 55 completed the informed consent, and 38 MPN patients completed the 12-week intervention. The majority of participants were diagnosed with either PV (n = 16) or ET (n = 16), with MF being less common (n = 6). Approximately 37% (n = 14) of study participants averaged ≥60 min/week of yoga (i.e., demand). Yoga participation averaged 50.8±36.2 min/week. Overall, 68% of participants were satisfied with online yoga and 75% felt that is was helpful for coping with MPN-related symptoms (i.e., acceptability, practicality). Additionally, 75% of participants felt safe from injury while participating in online yoga. Only one adverse event was reported (irritated enlarged spleen). From week 0 to week 12 (n = 38), there were significant improvements in total symptom burden (effect size [ES] in standard deviation units = -0.36, p = 0.004), anxiety (ES = -0.67, p = 0.002), depression (ES = -0.41, p = 0.049), sleep (ES = -0.58, p < 0.001), and fatigue (ES = -0.33, p = 0.04). These improvements remained significant at follow-up week 16 (n = 28) for all outcome measures with a trend for maintained fatigue improvement (ES = -0.34, p = 0.06) (see Table 1). There were no significant differences in outcomes between those that averaged < 60 min/week of yoga compared to those that averaged ≥60 min/week of yoga. Conclusions: A 12-week online yoga intervention is feasible (i.e., accepted, practical) for MPN patients and merits a randomized trial as complementary therapy.

TPS3630 Background: In metastatic colorectal cancer with deficient DNA mismatch repair (MMR), anti-PD-1 antibody monotherapy produced high tumor response rates and extended progression-free survival compared to lack of benefit for proficient MMR tumors (Le, M, et al, NEJM 2016). We propose a phase III randomized trial to determine if the addition of the anti-PD-L1 antibody, atezolizumab (Genentech™), to adjuvant FOLFOX can improve patient disease-free survival (DFS) vs FOLFOX alone in patients with stage III colon cancers with dMMR or microsatellite instability (MSI). By blocking the PD-1/PD-L1 interaction, atezolizumab may activate T cells, thereby, restoring their ability to detect and attack tumor cells. Limited data suggest that FOLFOX may increase intratumoral cytotoxic CD8+ T cells that may serve as ‘immune priming.’ Methods: Patients with curatively resected stage III colon carcinomas with evidence of dMMR or MSI will be randomized to modified FOLFOX6 for 6 months (12 cycles) alone or combined with atezolizumab (840 mg IV q2 wk) continued as monotherapy for an additional 6 months (total duration of 12 months). Patients will be stratified by T, N stage and tumor sidedness. Local testing for MSI or MMR proteins is allowed. Atezolizumab must begin by/with cycle 2. The targeted accrual goal of 700 patients provides 90% power to detect an effect size expressed as hazard ratio of 0.6 for the primary endpoint DFS at two-sided alpha of 0.05. Interim analyses are planned at 50% and 75% of events. Secondary endpoints include overall survival, treatment tolerability, and quality of life. This study will be conducted by the Alliance for Clinical Trials in Oncology. The protocol has been approved by NCI CTEP and is expected to be activated in mid 2017. Clinical trial information: NCT02912559.
