Randomized Open Label Phase III Trial of Irinotecan Plus Capecitabine versus Capecitabine Monotherapy in Patients with Metastatic Breast Cancer Previously Treated with Anthracycline and Taxane: PROCEED Trial (KCSG BR 11-01).

ABSTRACT: PURPOSE:We investigated whether irinotecan plus capecitabine improved progression-free survival (PFS) compared with capecitabine alone in patients with human epidermal growth factor 2 (HER2) negative and anthracycline and taxane pretreated metastatic breast cancer (MBC). Materials and Methods:A total of 221 patients were randomly assigned to irinotecan (80 mg/m2, days 1 and 8) and capecitabine (1,000 mg/m2 twice a day, days 1-14) or capecitabine alone (1,250 mg/m2 twice a day, days 1-14) every 3 weeks. The primary endpoint was PFS. RESULTS:There was no significant difference in PFS between the combination and monotherapy arm (median, 6.4 months vs. 4.7 months; hazard ratio [HR], 0.84; 95% confidence interval [CI], 0.63 to 1.11; p=0.84). In patients with triple-negative breast cancer (TNBC, n=90), the combination significantly improved PFS (median, 4.7 months vs. 2.5 months; HR, 0.58; 95% CI, 0.37 to 0.91; p=0.02). Objective response rate was numerically higher in the combination arm, though it failed to reach statistical significance (44.4% vs. 33.3%, p=0.30). Overall survival did not differ between arms (median, 20.4 months vs. 24.0 months; p=0.63). While grade 3 or 4 neutropenia was more common in the combination arm (39.6% vs 9.0%), hand-foot syndrome was more often observed in capecitabine arm. Quality of life measurements in global health status was similar. However, patients in the combination arm showed significantly worse symptom scales especially in nausea/vomiting and diarrhea. CONCLUSION:Irinotecan plus capecitabine did not prove clinically superior to single-agent capecitabine in anthracycline- and taxane-pretreated HER2 negative MBC patients. Toxicity profiles of the two groups differed but were manageable. The role of added irinotecan in patients with TNBC remains to be elucidated.

Project description:ImportanceThere is therapeutic uncertainty regarding use of combination or single-agent chemotherapy in the treatment of patients with gallbladder cancer who experience disease progression after first-line chemotherapy.ObjectiveTo compare the efficacy of capecitabine plus irinotecan (CAPIRI) vs irinotecan (IRI) alone in patients with advanced gallbladder cancer (GBC) who have disease progression after gemcitabine-based first-line treatment.Design, setting, and participantsThe GB-SELECT trial was a multicenter, open-label, phase 2, randomized clinical trial of CAPIRI vs IRI alone for treatment of gallbladder cancer in patients who had disease progression after prior gemcitabine-based chemotherapy.The study was carried out in 2 tertiary care institutions in India. Patients aged between 18 and 70 years with histopathologic diagnosis of adenocarcinoma gallbladder, advanced or metastatic disease, previous treatment with gemcitabine-based chemotherapy, adequate hematologic, liver, and renal functions, and ECOG performance status of 1 or less were included in the study between August 2018 and January 2020. The data were analyzed for this report with cutoff on May 19, 2020.InterventionsPatients were randomized 1:1 to receive capecitabine, 1700 mg/m2 per day, on days 1 to 14 plus intravenous irinotecan, 200 mg/m2, on day 1 or intravenous irinotecan, 240 mg/m2, on day 1, in 21-day cycles until disease progression or unacceptable toxic effects.Main outcomes and measuresThe primary end point was overall survival (OS) at 6 months. The secondary end points were progression-free survival and quality of life.ResultsA total of 98 patients were randomized, 49 in each arm, with median (range) age of 51 (29-70) years, with 60 (61%) being women. In the CAPIRI vs IRI arms, the number of deaths at 6 months, 6-month OS, and median OS were 35, 34, 38.4% (95% CI, 24.2%-52.6%) and 5.16 (95% CI, 4.26-6.06) months vs 34, 29, 54.2% (95% CI, 39.4%-69.0%) and 6.28 (95% CI, 4.25-8.30) months, respectively, with a hazard ratio of 1.02 (95% CI, 0.64-1.49, P = .93). There were no chemotherapy-related deaths but more patients required dose modification in CAPIRI compared with the IRI arm (13 [27%] vs 4 [9%], respectively, P = .03).Conclusions and relevanceThere was no significant difference in OS between treatment with capecitabine plus irinotecan or irinotecan alone among previously treated patients with gallbladder cancer. Single-agent irinotecan should be the preferred treatment option for such patients.Trial registrationCTRI/2017/10/010112.

Project description:BackgroundTaxanes usually follow anthracyclines in breast cancer neo/adjuvant treatment, likely because of their later introduction into clinical practice. However, there is no biological rationale that justifies this current standard of care. We compared a taxane followed by an anthracycline-based regimen with the reverse sequence in the neoadjuvant setting.Patients and methodsIn a randomized, open-label, single-center phase II trial, women with inoperable, locally advanced, HER2-negative breast cancer were stratified by hormone receptor status and randomized to three cycles of docetaxel (T) followed by three cycles of fluorouracil, doxorubicin, and cyclophosphamide (FAC) versus three cycles of FAC followed by three cycles of docetaxel. Surgery, radiotherapy, and adjuvant hormonal therapy were administered as per local guidelines. The primary endpoint was pathological complete response (pCR), and secondary endpoints included toxicity, event-free survival (EFS), and overall survival (OS).ResultsTreatment sequence did not improve pCR, which was 7% with T-FAC and 3% with FAC-T. However, after a median follow-up of 79 months, the 5-year EFS rate was 75.7% (95% confidence interval [CI], 65.4%-87.7%) with T-FAC and 48.2% (95% CI, 37.0%-62.7%) with FAC-T (hazard ratio [HR], 0.46; 95% CI, 0.26-0.81; log-rank p = .0054), and the 5-year OS rate was 89.7% (95% CI, 82.2%-97.8%) with T-FAC and 64.7% (95% CI, 53.6%-78.1%) with FAC-T (HR, 0.41; 95% CI, 0.22-0.78; p = .0052). There were no unexpected toxicities.ConclusionWe showed for the first time an improvement in EFS and OS with taxane-first compared with anthracycline-first sequencing chemotherapy in HER2-negative, locally advanced breast cancer. Confirmation of these results may have implications for clinical practice. This trial was registered with Clinicatrials.gov identifier NCT01270373.Implications for practiceThe NeoSAMBA trial showed a benefit for taxane-first sequencing chemotherapy consistent with the systematic review of the literature as well as the larger Neo-tAnGo study. Many recent and current ongoing clinical trials have already followed this treatment strategy. As a taxane-before-anthracycline sequence carries neither an incremental cost nor an increased toxicity, and given the available literature on this issue, reinforced that taxane-first regimen can be easily incorporated into daily clinical practice while awaiting confirmation of these findings from larger trials.

Project description:PurposeMetastatic breast cancer (MBC) remains an incurable disease despite major therapeutic advances. Pseudomonas aeruginosa-mannose-sensitive hemagglutinin (PA-MSHA) has been established to have anti-proliferative effects against breast cancer cells in preclinical experiments, and is indicated for treatment of cancer in China. We performed a phase II trial combining PA-MSHA with capecitabine in patients with heavily pretreated MBC.MethodsEligibility criteria included human epidermal growth factor receptor 2-negative MBC, prior therapy with anthracyclines and taxanes, at least one prior chemotherapy regimen for metastatic disease or early relapse after a taxane plus anthracycline adjuvant regimen, and adequate organ function and performance status. PA-MSHA 1 mg was administered subcutaneously every other day and capecitabine 1000 mg/m2 orally twice a day for 2 weeks on, 1 week off. The primary end point was progression-free survival.ResultsA total of 97 patients were enrolled. Median progression-free survival (PFS) was 4.0 months [95 % confidence interval (CI) 3.0-4.9], which was not significantly different from that in historical controls. However, median PFS was significantly longer (8.2 months; 95 % CI 6.7-9.7) in 24 patients with moderate immune-related adverse events (irAEs) such as fever or skin induration at the injection site than in those with no or mild irAEs (3.1 months, 95 % CI 2.5-3.6; p = 0.003). Overall survival was also improved in these patients (25.4 vs. 16.4 months; p = 0.044). PA-MSHA has a good safety profile, with only 6 patients (6.2 %) discontinuing treatment. PA-MSHA did not increase capecitabine-related toxicities such as hand-foot syndrome, nausea, and vomiting.ConclusionAdding PA-MSHA to capecitabine has a good safety profile in patients with heavily pre-treated MBC, although benefit from this regimen might occur only in patients with moderate PA-MSHA-related adverse events.Trial registrationClinicalTrials.gov NCT01380808.
