AbstractTrifluridine/tipiracil increases overall survival (OS) in patients with refractory, metastatic colorectal cancer (mCRC). A post hoc exploratory analysis of the RECOURSE randomized clinical trial (RCT) established two categories, a good prognosis corresponding to subjects having a low tumor burden and indolent disease. Other models in refractory mCRC are the FAS-CORRECT and Colon Life nomogram. The main objective was to externally validate the prognostic factors of the RECOURSE and FAS-CORRECT trials, and the Colon Life nomogram in a multicenter, real-world series of mCRC treated in 3rd and successive lines with trifluridine/tipiracil. The secondary aim was to develop an OS predictive model, TAS-RECOSMO. Between 2016 and 2019, 244 patients were recruited. Median OS was 8.15 vs 8.12 months for the poor (85% of the subjects) and good (15%) prognosis groups from the RESOURCE trial, respectively, log-rank p = 0.9. The most common grade 3–4 toxicities were neutropenia (17%), asthenia (6%), and anemia (5%). The AFT lognormal model TAS-RECOSMO included six variables: ECOG-PS, KRAS/NRAS/BRAF mutation status, time between diagnosis of metastasis and beginning of trifluridine/tipiracil, NLR, CEA, and alkaline phosphatase. The model’s bootstrapped bias-corrected c-index was 0.682 (95% CI, 0.636–0.722). The factors from the Colon Life model, FAS-CORRECT, and RECOURSE displayed a c-index of 0.690, 0.630, and 0.507, respectively. TAS-RECOSMO, FAS-CORRECT, and the Colon Life nomogram appear to predict OS in patients with refractory mCCR who begin trifluridine/tipiracil treatment in the real world. The prognostic groups of the RECOURCE RCT were unable to capture the situation of real-world subjects treated with trifluridine/tipiracil in this series.

677 Background: The Phase III RECOURSE trial, in patients (pts) with metastatic colorectal cancer (mCRC) refractory to standard therapies, demonstrated that trifluridine/tipiracil (FTD/TPI) significantly extended overall survival (OS) and progression-free survival (PFS) versus placebo in all subgroups, regardless of age, geographical origin, or KRAS status, with acceptable safety. Literature reports have shown optimal benefit for pts with low tumor burden (< 3 metastatic sites), indolent disease (≥ 18 mo since diagnosis of first metastasis), ECOG PS 0-1, and no liver metastasis when treated in late line mCRC. Methods: This exploratory post hoc analysis of RECOURSE (all ECOG 0-1) compared pts on FTD/TPI or placebo with good prognostic characteristics (GPC; low tumor burden and indolent disease) and poor prognostic characteristics (PPC; high tumor burden and/or aggressive disease). These subgroups were then analyzed by liver metastasis at baseline, ECOG PS, KRAS status and age. Results: Baseline characteristics were generally similar between the two groups. GPC placebo pts performed better than the PPC placebo pts, but worse than the GPC pts treated with FTD/TPI. GPC pts treated with FTD/TPI showed median OS of 9.3 mo versus 5.3 mo in PPC pts (HR 0.46; 95% CI: 0.37, 0.57; p < 0.0001); there was a similar effect for PFS. GPC pts had significantly better mOS and mPFS regardless of age (≥ 65 vs. < 65 y), ECOG PS (0–1), KRAS status (mutant vs. wildtype), and liver metastasis (y/n). No liver metastasis was the best prognostic factor: mOS in such pts treated with FTD/TPI was 16.4 mo and 7.6 mo in the GPC (n = 97) and PPC (n = 35) groups, respectively (HR 0.42; 95% CI: 0.24, 0.74; p < 0.0019); there was a similar effect for PFS. Pts with ECOG PS 0 at baseline remained PS 0-1 at discontinuation in 96% of the GPC group. Conclusions: Low tumor burden and indolent disease indicate good prognosis in late line mCRC. Pts with no liver metastasis have the best prognosis and are likely to have longer OS. GPCs might explain the percentage of long-term responders on FTD/TPI in RECOURSE. Maintenance of ECOG PS 0–1 during treatment is crucial in the continuum of care, allowing pts to benefit from further treatment options. Clinical trial information: NCT01607957.

The Impact

Abstract Background Patient-reported outcomes (PROs) are commonly collected in clinical trials and should provide impactful evidence on the effect of interventions on patient symptoms and quality of life. However, it is unclear how PRO impact is currently realised in practice. In addition, the different types of impact associated with PRO trial results, their barriers and facilitators, and appropriate impact metrics are not well defined. Therefore, our objectives were: i) to determine the range of potential impacts from PRO clinical trial data, ii) identify potential PRO impact metrics and iii) identify barriers/facilitators to maximising PRO impact; and iv) to examine real-world evidence of PRO trial data impact based on Research Excellence Framework (REF) impact case studies. Methods Two independent investigators searched MEDLINE, EMBASE, CINAHL+, HMIC databases from inception until December 2018. Articles were eligible if they discussed research impact in the context of PRO clinical trial data. In addition, the REF 2014 database was systematically searched. REF impact case studies were included if they incorporated PRO data in a clinical trial. Results Thirty-nine publications of eleven thousand four hundred eighty screened met the inclusion criteria. Nine types of PRO trial impact were identified; the most frequent of which centred around PRO data informing clinical decision-making. The included publications identified several barriers and facilitators around PRO trial design, conduct, analysis and report that can hinder or promote the impact of PRO trial data. Sixty-nine out of two hundred nine screened REF 2014 case studies were included. 12 (17%) REF case studies led to demonstrable impact including changes to international guidelines; national guidelines; influencing cost-effectiveness analysis; and influencing drug approvals. Conclusions PRO trial data may potentially lead to a range of benefits for patients and society, which can be measured through appropriate impact metrics. However, in practice there is relatively limited evidence demonstrating directly attributable and indirect real world PRO-related research impact. In part, this is due to the wider challenges of measuring the impact of research and PRO-specific issues around design, conduct, analysis and reporting. Adherence to guidelines and multi-stakeholder collaboration is essential to maximise the use of PRO trial data, facilitate impact and minimise research waste.

Aim: To assess real-world occurrence of common clinical trial-reported adverse events (AE) among patients with recurrent ovarian cancer initiating niraparib 200 mg/day. Materials & methods: This retrospective observational study used physician-extracted anonymized medical record data of eligible patients initiating niraparib 200 mg/day after platinum-based chemotherapy. Results: Of 153 patients, 57 (37%) experienced ≥1 of the three most common all-grade AEs within 3 months after niraparib initiation: nausea (16%; grade 3/4: 2%), thrombocytopenia (14%; grade 3/4: 3%) and fatigue (24%; grade 3/4: 3%). In the ENGOT-OV16/NOVA trial, these respective AEs occurred in 74, 61 and 59% of patients. Conclusion: Incidence of common clinical trial-reported AEs was lower among patients initiating niraparib 200 mg/day in real-world practice versus patients initiating niraparib 300 mg/day in ENGOT-OV16/NOVA.

Migraine is a prevalent and disabling disorder involving central and peripheral neurologic processes that generate inflammatory mediated pain. Cambia® (diclofenac potassium for oral solution), a novel patented form of the anti-inflammatory medication diclofenac potassium, has been approved by the US Food and Drug Administration for the acute treatment of migraine. Clinical trial data have demonstrated that this formulation offers a four-fold decrease in time of onset of relief compared with conventional diclofenac, which has comparable efficacy to triptan medication. It has also proven effective in a real-world setting. Over the past few years, it has been established that migraine treatment that is administered early may prevent central sensitization and improve treatment outcomes. Given the importance of early intervention in migraine treatment, this medication offers rapid, convenient, and effective relief with a favorable side-effect profile. This review describes migraine pathophysiology, treatment rationale, clinical trial results, and real-world experience with the use of this new medication.

3559 Background: Cetuximab is an IgG monoclonal antibody targeting the EGFR showing to be effective both as single agent or in combination with Irinotecan (CPT-11) or Irinotecan/FU/FA in patients (pts) with EGFR-expressing metastatic colorectal cancer (CRC) in the first and second/subsequent-line setting. The current trial was designed to evaluate the efficacy and the safety of Cetuximab plus Folfox-4 as first -line treatment. The main objective was the percentage of confirmed objective response rate. Methods: Chemonaivepts with non-resectable metastatic CRC and expressing EGFR were treated with Cetuximab (400 mg/m2 week 1 and 250 mg/m2 weekly thereafter) plus Folfox-4 (every 2 weeks: Oxaliplatin 85 mg/m2, day 1; FA 100 mg/m2 2h, simultaneously with OH-P, and FU 400 mg/m2 iv bolus followed by 600 mg/m2 iv for 22h on days 1 and 2). The first evaluation of disease status (Recist criteria) was performed after the first 4 cycles and confirmed after one month. The treatment was continued until a maximum of 12 cycles of chemotherapy; the maintenaice with Cetuximab was permitted. Preliminary results: On the 65 screened pts, 47 (72%) had EGFR-expressing metastatic disease and were enrolled. Their main characteristics were: median Ecog PS 0; median age 66 yrs (range 43–74); main sites of disease: liver 31, lung 12, lymph-nodes 3, others 8. To date twenty-two pts are evaluable for activity and 27 for toxicity; 2 pts are not evaluable and 25 are too early. We observed 16 PR (72.7%), 5 NC (22.7%) and 1 PD (4.6%) for an ORR of 72.7% and a TGCR of 95.4%; the confirmed PR were 15 (68%). To date 2 pts undergone surgery of their metastases both for lung. The main adverse events grade 3/4 (NCI criteria) were: acne-like rush 18.5%, diarrea 7%, nausea/vomiting 4% and anemia 4%. Conclusions: Our preliminary results confirm that the combination of Cetuximab plus Folfox-4 has an high activity and a good safety profile in advanced CRC pts. The study is ongoing.
