PurposeThis phase III study compared the safety and efficacy of the following three different irinotecan-containing regimens in the first-line treatment of metastatic colorectal cancer: irinotecan plus infusional fluorouracil (FU)/leucovorin (LV) (FOLFIRI), irinotecan plus bolus FU/LV (mIFL), and irinotecan plus oral capecitabine (CapeIRI).Patients and MethodsA total of 430 previously untreated metastatic colorectal cancer patients were randomly assigned to receive FOLFIRI (n = 144), mIFL (n = 141), or CapeIRI (n = 145). Patients were concurrently randomly assigned to a double-blind treatment with celecoxib or placebo. After a protocol amendment, an additional 117 patients were randomly assigned to either FOLFIRI plus bevacizumab (FOLFIRI+Bev; n = 57) or mILF plus bevacizumab (mIFL+Bev; n = 60), whereas the CapeIRI arm was discontinued. The primary study end point was progression-free survival (PFS), with secondary end points of overall survival (OS), response rate, and toxicity.ResultsMedian PFS was 7.6 months for FOLFIRI, 5.9 months for mIFL (P = .004 for the comparison with FOLFIRI), and 5.8 months for CapeIRI (P = .015). Median OS was 23.1 months for FOLFIRI, 17.6 months for mIFL (P = .09), and 18.9 months for CapeIRI (P = .27). CapeIRI was associated with higher rates of severe vomiting, diarrhea, and dehydration. After the amendment to add bevacizumab, the median survival time has not yet been reached for FOLFIRI+Bev and was 19.2 months for mIFL+Bev (P = .007). FOLFIRI+Bev was associated with a higher rate of ≥ grade 3 hypertension than mIFL+Bev.ConclusionFOLFIRI and FOLFIRI+Bev offered superior activity to their comparators and were comparably safe. An infusional schedule of FU should be the preferred irinotecan-based regimen in first-line metastatic colorectal cancer.

3575 Background: The literature reports that adding biologics to chemotherapy (ctx) may increase the incidence of clinically significant neutropenia. his trial was conducted to evaluate the efficacy of PEG in reducing the incidence of febrile neutropenia (FN) in pts with locally-advanced (LA) or metastatic (m)CRC receiving first-line treatment with either FOLFOX/B or FOLFIRI/B. Methods: Key eligibility: ≥ 18 years old; measurable, nonresectable CRC per RECIST 1.1. Pts were randomly assigned 1:1 to either placebo or 6 mg PEG ~24 h after ctx/B. The study treatment period included four Q2W cycles, but pts could continue their assigned regimen until progression. Pts were stratified by region (North America vs rest of world), stage (LA vs mCRC), and ctx (FOLFOX vs FOLFIRI). Estimated sample size (N = 800) was based on the expected incidence of grade 3/4 FN (primary endpoint) across the first 4 cycles of ctx/B, powered for PEG superiority over placebo. Other endpoints included overall response rate (ORR), progression-free survival (PFS), and overall survival (OS). Results: 845 pts were randomized (Nov 2009 to Jan 2012) and received study treatment; 783 pts completed 4 cycles of ctx/B. Median age was 61 years; 512 (61%) pts were male; 819 (97%) had mCRC; 414 (49%) received FOLFOX, and 431 (51%) received FOLFIRI. Grade 3/4 FN (first 4 cycles) for placebo vs PEG was 5.7% vs 2.4%; OR 0.41; p = 0.014. A similar incidence of other ≥ grade 3 adverse events was seen in both arms (28% placebo; 27% PEG). See table for additional results. Conclusions: PEG significantly reduced the incidence of grade 3/4 FN in this pt population receiving standard ctx/B for CRC. Follow-up is ongoing. Clinical trial information: NCT00911170. [Table: see text]

3508 Background: Treatment options for third-line metastatic colorectal cancer (mCRC) patients remain limited in China. Fruquintinib, an oral kinase inhibitor selectively targeting vascular endothelial growth factor receptors, in a phase II study was found to significantly improve progression free survival (“PFS”) in patients with mCRC as compared to placebo (ESMO abs#2111). Based on these results, a Phase III registration trial, FRESCO, was carried out to confirm fruquintinib’s efficacy and safety in third-line mCRC patients (clinicaltrials.gov # NCT02314819). Methods: This is a randomized, double-blind, placebo-controlled, multi-center phase III trial. Patients with mCRC who have failed at least 2 lines of systemic chemotherapy were enrolled from 28 centers in China. Patients were stratified based on prior anti-VEGF therapy and K-ras status and randomized to a fruquintinib or placebo arm in a 2:1 ratio. The primary endpoint was overall survival (“OS”) which was analyzed in the intent-to-treat population. Results: Between December 12, 2014 and May 13, 2016, 416 patients were randomized. Protocol predefined number of OS events for final analysis was reached on January 17, 2017. Fruquintinib significantly improved OS comparing to placebo with a hazard ratio of 0.65 (95% CI: 0.51-0.83; two sided p<0.001). Median OS was 9.30 months [95% CI 8.18-10.45] in the fruquintinib group versus 6.57 months [95% CI 5.88-8.11] in the placebo group. Statistically significant benefits were also seen with fruquintinib in all secondary endpoints, such as PFS, objective response rate and disease control rate. The most frequent fruquintinib-related ≥ Grade 3 treatment emerged adverse events included hypertension (21.6%), hand-foot skin reaction (10.8%), proteinuria (3.2%) and diarrhea (3.2%). Conclusion: In this phase III confirmatory trial, fruquintinib demonstrated a statistically significant and clinically meaningful OS benefit as compared with placebo in mCRC patients in China. Fruquintinib was well tolerated with a safety profile that is consistent with what was reported previously. Clinical trial information: NCT02314819.

Purpose Trifluridine/tipiracil (TAS-102) was effective in patients with metastatic colorectal cancer (mCRC) in a phase II Japanese trial. This regional trial evaluated the efficacy and safety of trifluridine/tipiracil in Asian patients with mCRC with or without exposure to biologic therapy. Patients and Methods This randomized, double-blind, placebo-controlled, phase III trial was conducted at 30 sites in China, the Republic of Korea, and Thailand. Patients ≥ 18 years old with histologically or cytologically confirmed adenocarcinoma of the colon or rectum and known KRAS status who were refractory or intolerant to two or more prior chemotherapy regimens were enrolled. Eligible patients were randomly assigned (2:1 ratio; minimization method) to receive trifluridine/tipiracil (twice per day orally; 5 days on and 2 days off for 2 weeks, followed by 14 days off per cycle) or placebo. The primary end point was overall survival (intent-to-treat population). Results Between October 16, 2013, and June 15, 2015, 406 patients were randomly assigned to receive trifluridine/tipiracil (n = 271) or placebo (n = 135). Risk of death was significantly lower in the trifluridine/tipiracil arm than in the placebo arm (hazard ratio for death, 0.79; 95% CI, 0.62 to 0.99; log-rank P = .035). Median overall survival was significantly longer in the trifluridine/tipiracil than in the placebo arm (7.8 months [95% CI, 7.1 to 8.8 months] v 7.1 months [95% CI, 5.9 to 8.2 months], respectively), for a median survival follow-up time of 13.8 months (95% CI, 13.1 to 15.3 months) compared with 13.4 months (95% CI, 11.6 to 17.3 months), respectively. The incidence of serious adverse events was similar between the arms (trifluridine/tipiracil, n = 63 [23.2%]; placebo, n = 32 [23.7%]). No treatment-related deaths were reported. Conclusion Trifluridine/tipiracil has a statistically significant survival benefit compared with placebo in Asian patients with mCRC refractory or intolerant to standard chemotherapies, regardless of exposure to biologic therapy. The safety profile is similar to previous reports.

AbstractIntroduction:Metastatic colorectal cancer (mCRC) is one of the most common cancers and the second leading cause of cancer worldwide. With the improvement of systemic and operative therapies, median overall survival (mOS) reached 30 months or longer. Here, we will review the use of the anti-vascular endothelial growth factor (VEGF) and anti-epidermal growth factor receptor (EGFR) antibodies in combination with doublet and triplet chemotherapy in patients with borderline and primary unresectable mCRC.Methods:Phases II and III trials were included in investigating chemotherapy in the first-line in combination with an anti-VEGF(R) or anti-EGFR in a cohort of patients with mCRC.Results:The VEGF-antibody bevacizumab has improved progression-free survival (PFS) in several phase III trials in combination with a chemotherapy doublet. More recently, a higher efficacy has been demonstrated in combination with an intensified chemotherapy including 5-fluoropyrimidine (5-FU), oxaliplatin, and irinotecan within the phase III TRIBE study. Similarly, high resectability rates have been shown in the phase II Olivia trial for patients with liver-limited disease with an intensified chemotherapeutic regime. However, this increase in efficacy was accompanied by an increase in toxicity as well. The efficacy of the EGFR-antibodies cetuximab and panitumumab has been shown in several phase III trials, but their use is restricted to patients whose tumors are RAS wildtype (WT). The phase II trials, CELIM and PLANET, demonstrated a favorable long-term survival for patients with initially non-resectable colorectal liver metastases who respond to conversion therapy with EGFR-antibodies and undergo secondary resection. The CLGB and FIRE-3 trials delivered an inconsistent finding whether anti-VEGF or -EGFR treatment is the better option in the first-line setting. However, there is increasing evidence from post hoc analyses of prospective clinical trials that patients with left-sided tumors benefit from EGFR-directed combination therapy in terms of prolongation of OS and PFS compared with limited, if any, benefit for those with right-sided tumors.Conclusion:Both anti-VEGF- and anti-EGFR-directed therapies represent efficient treatment options for patients with mCRC in the first line. For patients with RAS WT, left-sided tumor anti-EGFR-based treatment is recommended. Intensified regimens can be offered initially to unresectable patients in order to achieve resectability at a price of higher toxicity.
