Purpose This randomized study assessed whether the best overall response rate (ORR) of cetuximab combined with oxaliplatin, leucovorin, and fluorouracil (FOLFOX-4) was superior to that of FOLFOX-4 alone as first-line treatment for metastatic colorectal cancer. The influence of KRAS mutation status was investigated. Patients and Methods Patients received cetuximab (400 mg/m2 initial dose followed by 250 mg/m2/wk thereafter) plus FOLFOX-4 (oxaliplatin 85 mg/m2 on day 1, plus leucovorin 200 mg/m2 and fluorouracil as a 400 mg/m2 bolus followed by a 600 mg/m2 infusion during 22 hours on days 1 and 2; n = 169) or FOLFOX-4 alone (n = 168). Treatment was continued until disease progression or unacceptable toxicity. KRAS mutation status was assessed in the subset of patients with assessable tumor samples (n = 233). Results The confirmed ORR for cetuximab plus FOLFOX-4 was higher than with FOLFOX-4 alone (46% v 36%). A statistically significant increase in the odds for a response with the addition of cetuximab to FOLFOX-4 could not be established (odds ratio = 1.52; P = .064). In patients with KRAS wild-type tumors, the addition of cetuximab to FOLFOX-4 was associated with a clinically significant increased chance of response (ORR = 61% v 37%; odds ratio = 2.54; P = .011) and a lower risk of disease progression (hazard ratio = 0.57; P = .0163) compared with FOLFOX-4 alone. Cetuximab plus FOLFOX-4 was generally well tolerated. Conclusion KRAS mutational status was shown to be a highly predictive selection criterion in relation to the treatment decision regarding the addition of cetuximab to FOLFOX-4 for previously untreated patients with metastatic colorectal cancer.

TPS810 Background: The optimal duration and content of first-line therapy in mCRC pts once they have achieved objective response is controversial. In the FIRE-3 trial, ETS was significantly associated with PFS and OS. Based on this evidence it can be hypothesized that once this goal has been achieved, further exposure to combined antineoplastic treatment may not result in improvement or preservation of such result but only in an increase of toxicity. We designed a strategy study to compare FOLFIRI + cetuximab until PD to FOLFIRI + cetuximab for 8 cycles followed by cetuximab alone until PD in first line treatment of RAS/BRAF WT mCRC pts. Methods: This is a multicenter, open-label, randomized phase III trial. Untreated and unresecteble RAS/BRAF WT mCRC pts were randomized 1:1 to receive Cetuximab (400 mg/mq w1 and then 250 mg/mq weekly) + FOLFIRI until PD (standard arm) or Cetuximab (400 mg/mq week 1 and then 250 mg/mq weekly) + FOLFIRI for 8 cycles followed by Cetuximab monotherapy until PD (experimental arm). Tumor assessment is planned every 8 weeks. The objective of the study is to demonstrate a not inferior efficacy and a better toxicity profile for the experimental treatment compared to the standard treatment. The co-primary endpoints are PFS and incidence of G 3-4 AEs. Secondary endpoints are OS, ORR, ETS (8 weeks) and safety. A prospective multiple gene mutation analysis by NGS of both tumor tissue and blood will be performed to find potential predictive factors and surrogate markers of treatment efficacy. The two co-primary endpoints will be compared between the two arms using a fixed-sequence testing procedure to control for the family-wise type I error rate of 0.05 in a strong sense. This sequence considers that a reduction of grade 3-4 AEs is only of relevance, if non-inferiority is shown regarding PFS. 600 evaluable pts will be enrolled and randomized. Study recruitment started on January 2015, currently 139 pts have been randomized. Clinical trial information: NCT02484833.

Purpose The addition of cetuximab to irinotecan, fluorouracil, and leucovorin (FOLFIRI) as first-line treatment for metastatic colorectal cancer (mCRC) was shown to reduce the risk of disease progression and increase the chance of response in patients with KRAS wild-type disease. An updated survival analysis, including additional patients analyzed for tumor mutation status, was undertaken. Patients and Methods Patients were randomly assigned to receive FOLFIRI with or without cetuximab. DNA was extracted from additional slide-mounted tumor samples previously used to assess epidermal growth factor receptor expression. Clinical outcome according to the tumor mutation status of KRAS and BRAF was assessed in the expanded patient series. Results The ascertainment rate of patients analyzed for tumor KRAS status was increased from 45% to 89%, with mutations detected in 37% of tumors. The addition of cetuximab to FOLFIRI in patients with KRAS wild-type disease resulted in significant improvements in overall survival (median, 23.5 v 20.0 months; hazard ratio [HR], 0.796; P = .0093), progression-free survival (median, 9.9 v 8.4 months; HR, 0.696; P = .0012), and response (rate 57.3% v 39.7%; odds ratio, 2.069; P < .001) compared with FOLFIRI alone. Significant interactions between KRAS status and treatment effect were noted for all key efficacy end points. KRAS mutation status was confirmed as a powerful predictive biomarker for the efficacy of cetuximab plus FOLFIRI. BRAF tumor mutation was a strong indicator of poor prognosis. Conclusion The addition of cetuximab to FOLFIRI as first-line therapy improves survival in patients with KRAS wild-type mCRC. BRAF tumor mutation is an indicator of poor prognosis.

PURPOSE: To compare the response rate, efficacy parameters, and toxicity profile of oral capecitabine with bolus intravenous (IV) fluorouracil plus leucovorin (5-FU/LV) as first-line treatment in patients with metastatic colorectal cancer. PATIENTS AND METHODS: We prospectively randomized 605 patients to treatment with oral capecitabine for 14 days every 3 weeks or 5-FU/LV by rapid IV injection daily for 5 days in 4-week cycles. RESULTS: The overall objective tumor response rate among all randomized patients was significantly higher in the capecitabine group (24.8%) than in the 5-FU/LV group (15.5%; P = .005). In the capecitabine and 5-FU/LV groups, median times to disease progression were 4.3 and 4.7 months (log-rank P = .72), median times to treatment failure were 4.1 and 3.1 months (P = .19), and median overall survival times were 12.5 and 13.3 months (P = .974), respectively. Capecitabine, compared with bolus 5-FU/LV treatment, produced a significantly lower incidence (P < .0002) of diarrhea, stomatitis, nausea, and alopecia. Patients treated with capecitabine also displayed lower incidences of grade 3/4 stomatitis and grade 3/4 neutropenia (P < .0001) leading to significantly less neutropenic fever/sepsis. Grade 3 hand-foot syndrome (P < .00001) and grade 3/4 hyperbilirubinemia were the only toxicities more frequently associated with capecitabine than with 5-FU/LV treatment. CONCLUSION: Oral capecitabine was more active than 5-FU/LV in the induction of objective tumor responses. Time to disease progression and survival were at least equivalent for capecitabine compared with the 5-FU/LV arm. Capecitabine also demonstrated clinically meaningful benefits over bolus 5-FU/LV in terms of tolerability.
