Efficacy Criteria

Introduction. Trifluridine/Tipiracil (FTD/TPI) is a new chemotherapeutic drug approved in more than 60 countries for use in patients with metastatic colorectal cancer who have registered progression or intolerance to treatment with fluoropyrimidines, oxaliplatin and irinotecan, anti-VEGRand anti-EGFR-targeted agents. This study evaluated for the first time the effectiveness and tolerability of FTD/TPI therapy in the Russian patient population.Materials and methods. A confirmatory open-label single-arm non-randomized trial was conducted in 2 clinical centres in Russia. The main criteria for inclusion were: conduction of at least the 2nd line of standard systemic therapy for metastatic colon adenocarcinoma. The primary efficacy criteria were: 2-month progression-free survival; secondary – median progressionfree survival, disease control frequency, safety assessment, overall survival. Research number: NCT03274882.Results. A total of 26 patients were included in the study; the median age was 60.5 years (30 to 78); 19 (73%) women; and 4 patients with ECOG 0 and 22 – with ECOG 1. All patients were previously treated with the inclusion of oxaliplatin, irinotecan, fluoropyrimidines, 21 (81%) – bevacizumab, 6 (23%) – anti-EGFR antibodies, and 2 (7.7%) – regorafenib. The median for treatment courses was 4 (1–21), 11 (42.3%) patients were treated for 6 months or more. The two-month progression-free survival rate was 52% with a median progreesion-free survival rate of 4 months (95% CI 1.8–7.4 months). The median of total survival rate was 11 months (95% CI 5,2–16,8 months). Disease control was achieved in 60%. Neutropenia, nausea, vomiting, anemia, weakness prevailed among undesirable events associated with treatment (≥5 patients). The majority of complications were of the 1st–2nd degree. Among the undesirable events of the 3rd–4th degree, neutropenia was more common, while in 3 patients febrile neutropenia of the 3rd degree was registered.Conclusions. In the Russian population of patients with colorectal chemorefractory cancer, the drug FTD/TPI (TAS-102) shows efficacy and tolerability comparable to the RECOURSE registration study.

This paper presents a summary of the evidence review group (ERG) report into the clinical effectiveness and cost-effectiveness of bevacizumab in combination with fluoropyrimidine-based chemotherapy for the first-line treatment of metastatic colorectal cancer based on the manufacturer’s submission to the National Institute for Health and Clinical Excellence (NICE) as part of the single technology appraisal (STA) process. Evidence was available in the form of one phase III, multicentre, multinational, randomised, open-label study (NO16966 trial). This two-arm study was originally designed to demonstrate the non-inferiority of oral capecitabine plus oxaliplatin (XELOX) compared with 5-fluorouracil plus folinic acid plus oxaliplatin (FOLFOX)-4 in adult patients with histologically confirmed metastatic colorectal cancer who had not previously been treated. Following randomisation of 634 patients, the open-label study was amended to include a 2 × 2 factorial randomised (partially blinded for bevacizumab) phase III trial with the coprimary objective of demonstrating superiority of bevacizumab in combination with chemotherapy compared with chemotherapy alone. Measured outcomes included overall survival, progression-free survival, response rate, adverse effects of treatment and health-related quality of life. The manufacturer’s primary pooled analysis of superiority (using the intention-to-treat population) showed that after a median follow-up of 28 months, the addition of bevacizumab to chemotherapy significantly improved progression-free survival and overall survival compared with chemotherapy alone in adult patients with histologically confirmed metastatic colorectal cancer who were not previously treated [median progression-free survival 9.4 vs 7.7 months (absolute difference 1.7 months); hazard ratio (HR) 0.79, 97.5% confidence interval (CI) 0.72 to 0.87; p = 0.0001; median overall survival 21.2 vs 18.9 months (absolute difference 2.3 months); HR 0.83, 97.5% CI 0.74 to 0.93; p = 0.0019]. The NO16966 trial was of reasonable methodological quality and demonstrated a significant improvement in both progression-free survival and overall survival when bevacizumab was added to XELOX or FOLFOX. However, the size of the actual treatment effect of bevacizumab is uncertain. The ERG believed that the modelling structure employed was appropriate, but highlighted several key issues and areas of uncertainty. At the time of writing, NICE was yet to issue the guidance for this appraisal.

Purpose To determine whether adding bevacizumab, with or without mitomycin, to capecitabine monotherapy improves progression-free survival (PFS) in patients with metastatic colorectal cancer (mCRC) in an open-label, three-arm randomized trial. Patients and Methods Overall, 471 patients in Australia, New Zealand, and the United Kingdom with previously untreated, unresectable mCRC were randomly assigned to the following: capecitabine; capecitabine plus bevacizumab (CB); or capecitabine, bevacizumab, and mitomycin (CBM). We compared CB with capecitabine and CBM with capecitabine for progression-free survival (PFS). Secondary end points included overall survival (OS), toxicity, response rate (RR), and quality of life (QOL). Results Median PFS was 5.7 months for capecitabine, 8.5 months for CB, and 8.4 months for CBM (capecitabine v CB: hazard ratio [HR], 0.63; 95% CI, 0.50 to 0.79; P < .001; C v CBM: HR, 0.59; 95% CI, 0.47 to 0.75; P < .001). After a median follow-up of 31 months, median OS was 18.9 months for capecitabine and was 16.4 months for CBM; these data were not significantly different. Toxicity rates were acceptable, and all treatment regimens well tolerated. Bevacizumab toxicities were similar to those in previous studies. Measures of overall QOL were similar in all groups. Conclusion Adding bevacizumab to capecitabine, with or without mitomycin, significantly improves PFS without major additional toxicity or impairment of QOL.

631 Background: This study was designed to evaluate the influence of dose reduction and schedule modification on outcomes in patients with metastatic colorectal cancer (mCRC). Methods: Pooled datasets from two previous phase II trials of FOLFIRI (CCOG-0502; n = 36) and mFOLFOX6 (CCOG-0704; n = 30) in patients with mCRC were analyzed retrospectively. The RDIs of irinotecan and oxaliplatin were compared to response rate (RR), disease control rate (DCR), progression-free survival (PFS) and overall survival (OS). To assess the effects of dose reduction and time delay, we defined ‘dose index (DI)’ as the ratio of the actual delivered total dose to the planned total dose and ‘time index (TI)’ as the ratio of the planned duration to the actual duration of therapy. Relative dose intensity (RDI) was computed by multiplying DI by TI. DI and TI of irinotecan and oxaliplatin were compared to response rate (RR), disease control rate (DCR) and progression-free survival (PFS). Results: In patients receiving FOLFIRI therapy, the median DI and TI of irinotecan were 0.92 and 0.90, respectively. RRs were 59% vs. 12% in the higher vs. lower DI groups (p < 0.01), and 35% vs. 35% in the higher vs. lower TI groups (p = 1.00), respectively. Median PFS was 10.2 vs. 5.0 months in the higher vs. lower DI groups (p < 0.01), and 6.1 vs. 6.7 months in the higher vs. lower TI groups (p = 0.48), respectively. In mFOLFOX6 therapy, the median DI and TI of oxaliplatin were 0.97 and 0.82, respectively. RRs were 44% vs. 36% in the higher vs. lower DI groups (p = 0.65), and 44% vs. 36% in the higher vs. lower TI groups (p = 0.65), respectively. Median PFS was 7.7 vs. 6.7 months in the higher vs. lower DI groups (p = 0.13), and 8.5 vs. 5.9 months in the higher vs. lower TI groups (p = 0.02), respectively. Multivariate analyses showed that DI of irinotecan (HR 8.48; 95% CI, 2.94-24.51, p < 0.01) and TI of oxaliplatin (HR 2.74; 95% CI, 1.02-7.33, p = 0.04) were the independent prognostic factors for PFS. Conclusions: Dose reductions in irinotecan and time delays in oxaliplatin could have significant impact on PFS in patients receiving FOLFIRI and FOLFOX6, respectively.

3527 Background: Apatinib is an oral highly-selective tyrosine kinase inhibitor (TKI) that blocks vascular endothelial growth factor receptor 2 (VEGFR-2). This exploratory study evaluated the efficacy and safety of apatinib monotherapy in patients with chemotherapy-refractory metastatic colorectal cancer. Methods: In this multicenter, single-arm, prospective study, 48 patients with metastatic colorectal cancer who had failed at least two lines standard chemotherapies including fluorouracil, oxaliplatin and irinotecan were recruited from 14 centers in Guangdong, China. Apatinib at a 500mg dose was administered daily continuously. Each cycle was 4 weeks (28 days). The primary endpoint was progression free survival (PFS). Secondary end points included overall survival (OS), objective response rate (ORR), disease control rate (DCR), quality of life (QoL) and toxicity. Results: A total of 48 patients was enrolled in the study from September 3, 2015 to June9, 2017. Four patients achieved a partial response, and 22 achieved stable disease, representing a response rate of 8.3% and a disease control rate of 60.4%. Median follow-up time was 10.3 months. Median progression-free survival (PFS) and overall survival (OS) of evaluable patients (n=41) were 4.7 months (95% confidence interval [CI] 3.7-5.9) and 9.7 months (95% CI 5.9-13.6). The most common grade 3 or 4 adverse events (AE) were hypertension (12.5%), hand-foot syndrome (10.4%), thrombocytopenia (10.4%), proteinuria (8.3%) and mucositis oral (6.3%). Conclusions: Apatinib monotherapy shows promising efficacy and manageable toxicities in patients with chemotherapy-refractory metastatic colorectal cancer. Further phase 3 trial is warranted.

PURPOSE This trial investigated the addition of panitumumab to triplet chemotherapy with fluorouracil/folinic acid, oxaliplatin, and irinotecan (FOLFOXIRI) in a two-to-one randomized, controlled, open-label, phase II trial in patients with untreated RAS wild-type (WT) metastatic colorectal cancer. PATIENTS AND METHODS The primary end point was objective response rate (ORR) according to RECIST (version 1.1). The experimental arm (modified FOLFOXIRI [mFOLFOXIRI] plus panitumumab) was considered active if the ORR was ≥ 75%. The experimental ORR was compared with an estimated ORR of 60% based on historical data, verified by a randomized control group (FOLFOXIRI). The power of the trial was 80%, with a potential type I error of 0.05. Secondary end points included secondary resection rate, toxicity, progression-free survival, and overall survival. RESULTS A total of 63 patients were randomly assigned to the experimental arm and 33 patients to the control arm. The ORR of the mFOLFOXIRI plus panitumumab arm exceeded 75% and was higher when compared with that of FOLFOXIRI (87.3% v 60.6%; odds ratio, 4.469; 95% CI, 1.61 to 12.38; P = .004). The secondary resection rate was improved with the addition of panitumumab (33.3% v 12.1%; P = .02). Progression-free survival was similar in the study arms, whereas overall survival showed a trend in favor of the panitumumab-containing arm (hazard ratio for death, 0.67; 95% CI, 0.41 to 1.11; P = .12). CONCLUSION The addition of panitumumab to mFOLFOXIRI in patients with RAS WT metastatic colorectal cancer improved the ORR and rate of secondary resection of metastases and represents a treatment option in selected and fit patients in need of highly active first-line therapy. Future studies should determine whether the addition of panitumumab to mFOLFOXIRI prolongs survival.

BACKGROUND: In recent times, scientists have found new treatments for colorectal cancer patients. AIM: The study is to evaluate the efficacy and toxicity of triplet combination chemotherapy of 5-fluorouracil/leucovorin, oxaliplatin, and irinotecan (FOLFOXIRI) for patients with metastatic colorectal cancer in stage IV. METHODS: Uncontrolled clinical trial carried on 39 stage IV colorectal cancer patients. RESULTS: The overall response rate of the treatment was 79.4%. The average progression-free survival was 13.4 ± 9 months. The overall survival rate at 12th month and 24th month were 90% and 76%, respectively. The proportion of granulocytopenia was 48.9%, no grade 3 or 4. Side effect beyond hematology was most seen in hepatic toxicity with 52.5%, mainly at grade 1. Vomiting was 18.3%, all at grade 1. Other adverse event was very low at percentage. CONCLUSIONS: The triplet combination FOLFOXIRI chemotherapy improves the outcome of patients with metastatic colorectal cancer regarding rate of response, overall survival rate and progression-free survival, and the level of toxicity was acceptable.

BackgroundLenvatinib inhibits tyrosine kinases, including vascular endothelial growth factor (VEGF) receptor, fibroblast growth factor receptor, platelet-derived growth factor receptor alpha, RET proto-oncogene and KIT proto-oncogene, receptor tyrosine kinase. We assessed the efficacy and safety of lenvatinib in patients with metastatic colorectal cancer after failure of standard chemotherapies.Patients and methodsThis was an open-label, single centre, single-arm, phase 2 study. Eligible patients had unresectable metastatic colorectal adenocarcinoma, refractory or intolerant to fluoropyrimidine, irinotecan, oxaliplatin, trifluridine/tipiracil, anti-VEGF therapy and anti-epidermal growth factor receptor therapy (for tumours with wild-type RAS). Patients were treated with oral lenvatinib at 24 mg one time a day in 28-day cycles until disease progression or unacceptable toxicity. The primary endpoint was centrally assessed disease control rate. Secondary endpoints included safety, response rate, progression-free survival and overall survival. The planned sample size was 30 patients to expect a disease control rate of 60% with a threshold disease control rate of 35%, one-sided alpha of 5% and power of 80%ResultsBetween 24 October 2016 and 23 January 2018, 30 patients were enrolled; 11 (37%) and 19 (63%) had received 3 or ≥4 lines of prior chemotherapy for metastatic disease, respectively. The median number of lenvatinib cycles was 4 (range 1–13). The centrally assessed disease control rate was 70.0% (21/30, 90% CI 53.5% to 83.4%, one-sided p=0.0001); 2 patients had a partial response and 19 had a stable disease. Median progression-free survival was 3.6 months (95% CI 2.6 to 3.7). Median overall survival was 7.4 months (95% CI 6.4 to 10.8). The most common grade ≥3 adverse events were hypertension (53%), thrombocytopenia (10%), increased alanine aminotransferase and anorexia (7% each).ConclusionsLenvatinib showed promising clinical activity and was tolerated in patients with metastatic colorectal cancer after failure of standard chemotherapies.Trial registration numberUMIN-CTR, UMIN000023446 and JAMCCT-CTR, JMA-IIA00261.

AbstractThere is an unmet medical need for later-line treatment options for patients with metastatic colorectal cancer (mCRC). Considering that, beyond progression, co-treatment with bevacizumab and cytotoxic chemotherapy showed less toxicity and a significant disease control rate, we aimed to evaluate the efficacy of capecitabine and bevacizumab. This single-center retrospective study included 157 patients between May 2011 and February 2018, who received bevacizumab plus capecitabine as later-line chemotherapy after progressing with irinotecan, oxaliplatin, and fluoropyrimidines. The study treatment consisted of bevacizumab 7.5 mg/kg on day 1 and capecitabine 1,250 mg/m2 orally (PO) twice daily on day 1 to 14, repeated every 3 weeks. The primary endpoint was progression-free survival (PFS). The median PFS was 4.6 months (95% confidence interval [CI] 3.9–5.3). The median overall survival (OS) was 9.7 months (95% CI 8.3–11.1). The overall response rate was 14% (22/157). Patients who had not received prior targeted agents showed better survival outcomes in the multivariable analysis of OS (hazard ratio [HR] = 0.59, 95% CI 0.43–0.82, P = 0.002) and PFS (HR = 0.61, 95% CI 0.43–0.85, P = 0.004). Bevacizumab plus capecitabine could be a considerably efficacious option for patients with mCRC refractory to prior standard treatments.

Abstract Background We aimed to assess the safety and efficacy of combination treatment with panitumumab plus trifluridine/tipiracil (FTD/TPI) in patients with wild-type RAS metastatic colorectal cancer (mCRC) who were refractory/intolerant to standard therapies other than anti-epidermal growth factor receptor therapy. Methods APOLLON was an open-label, multicentre, phase 1/2 trial. In the phase 1 part, 3 + 3 de-escalation design was used to investigate the recommended phase 2 dose (RP2D); all patients in the phase 2 part received the RP2D. The primary endpoint was investigator-assessed progression-free survival (PFS) rate at 6 months. Secondary endpoints included PFS, overall survival (OS), overall response rate (ORR), disease control rate (DCR), time to treatment failure (TTF), and safety. Results Fifty-six patients were enrolled (phase 1, n = 7; phase 2, n = 49) at 25 Japanese centres. No dose-limiting toxicities were observed in patients receiving panitumumab (6 mg/kg every 2 weeks) plus FTD/TPI (35 mg/m2 twice daily; days 1–5 and 8–12 in a 28-day cycle), which became RP2D. PFS rate at 6 months was 33.3% (90% confidence interval [CI] 22.8–45.3). Median PFS, OS, ORR, DCR, and TTF were 5.8 months (95% CI 4.5–6.5), 14.1 months (95% CI 12.2–19.3), 37.0% (95% CI 24.3–51.3), 81.5% (95% CI 68.6–90.8), and 5.8 months (95% CI 4.29–6.21), respectively. Neutrophil count decreased (47.3%) was the most common Grade 3/4 treatment-emergent adverse event. No treatment-related deaths occurred. Conclusion Panitumumab plus FTD/TPI exhibited favourable anti-tumour activity with a manageable safety profile and may be a therapeutic option for pre-treated mCRC patients.
