740 Background: The FOLFOX with bevacizumab (B-mab) has been established as a standard first-line therapy for metastatic colorectal cancer (mCRC), and OPTIMOX1 study suggested that stop and go strategy for oxaliplatin reduced peripheral sensory neuropathy. The CapeOx is one of the standard treatments for mCRC that has been proven to be as effective as the FOLFOX regimen. Thus we accessed the efficacy and safety of the combination of intermittent CapeOx + B-mab as a first-line therapy in patients with mCRC in this trial. Methods: Eligibility criteria included ECOG PS: 0–1, No Peripheral neuropathy ( < Grade 1). Patients received CapeOX (oxaliplatin 130mg/m2, capecitabine 2000mg/m2 + B-mab 7.5mg/kg) q3 weeks for 5 cycles, maintenance without oxaliplatin for 5 cycles, and reintroduction CapeOX + B-mab for 5 cycles until progression. Primary endpoint was Progression Free Survival (PFS). Results: Between March 2011 and August 2013, 55 pts were enrolled. Baseline characteristics were median age of 67 years (range, 20–83); PS 0/1 (49/6 pts); male/female (33/22 pts), colon/rectum (28/27pts) and metastatic lesion liver/lung/lymph nodes (32/18/21 pts). A total of 47 pts were evaluated as Par Protocol Set population. 38 pts moved from initial CapeOX to maintenance Capecitabine. 20 pts moved to CapeOx reintroduction. Median PFS was 14.7months (95%CI, 8.6–19.5) and Median TTF was 12.3 months (95%CI, 10.3–14.3). Best overall response rate was 48.0%. Oxaliplatin reintroduction rate was 57.4%. Main grade 3/4 toxicity were: neutropenia (1 pt), anemia (1 pt), peripheral neuropathy (1 pt), allergic reaction of oxaliplatin (1 pt), deep vein thrombosis (1 pt), nausea (1 pt), hand-foot syndrome (1 pt), and hypertension (1 pt). Conclusions: This study met its primary endpoint PFS. CapeOx intermittent oxaliplatin indicated to reduce incidence of severe neutropenia and peripheral sensory neuropathy. The results suggested that our treatment strategy was well tolerate and effective for first line therapy in mCRC, and maintenance duration for 5 cycles, was reasonable.

761 Background: In metastatic colorectal cancer (mCRC), the benefit of the molecular targeted drugs added to chemotherapy has been reported and a combination therapy of capecitabine (CAP) and oxaliplatin (CapeOX) plus bevacizumab (BEV) is an established first-line therapy for mCRC. However, the management of the cumlateve neurotoxicity of oxaliplatin still remains. We evaluated the efficacy and safety of CapeOX plus BEV with oxaliplatin stop and go strategy. Methods: Two prospective clinical trials of previously untreated unresectable mCRC were analyzed. Fifty four patients were treated with CapeOX plus BEV with oxaliplatin stop and go strategy (CCOG-0902). They were treated 4 cycles of CapeOX plus BV therapy followed by maintenance therapy of 8 cycles of Capecitabine plus BV and oxaliplatin reintroduction was scheduled after maintenance therapy or upon tumor progression. On the other group, forty seven patients were treated with mFOLFOX6 plus BEV (CCOG-0801). Progression free survival (PFS), overall survival (OS), response rate (RR), disease control rate (DCR), relative dose intensity (RDI), and frequency of peripheral sensory neuropathy (PSN) were evaluated. Results: Patient characteristics were balanced between the two groups. The median RDI of oxaliplatin in CCOG-0902 group was significantly higher, 92% than in CCOG-0801 group, 80%. RR and DCR were 61.5% and 96.3% respectively, in CCOG-0902 group, compared with 61.7% and 89.4% respectively, in CCOG-0801 group. Median PFS was 13.6 and 30.5 months, respectively, compared with 11.7 and 31.6 months, respectively, in CCOG-0801 group (p=not significant). The frequency of peripheral sensory neuropathy (PSN) was 19.0% (>Grade3: 1.9%) of patients in CCOG-0902 group compared with 72.3% (>grade 3: 17.0%) in CCOG-0801 group. Conclusions: CapeOX plus BV with oxaliplatin stop and go strategy could have same efficacy as continuing oxaliplatin with avoiding PSN. Clinical trial information: UMIN000006478.

Phase Iii Trials

Purpose Fluorouracil (FU)-leucovorin (LV), irinotecan, and oxaliplatin administered alone or in combination have proven effective in the treatment of advanced colorectal cancer (CRC). Combination protocols using FU-LV with either irinotecan or oxaliplatin are currently regarded as standard first-line therapies in this disease. However, the importance of the availability of all three active cytotoxic agents, FU-LV, irinotecan, and oxaliplatin, on overall survival (OS) has not yet been evaluated. Materials and Methods We analyzed data from seven recently published phase III trials in advanced CRC to correlate the percentage of patients receiving second-line therapy and the percentage of patients receiving all three agents with the reported median OS, using a weighted analysis. Results The reported median OS is significantly correlated with the percentage of patients who received all three drugs in the course of their disease (P = .0008) but not with the percentage of patients who received any second-line therapy (P = .19). In addition, the use of combination protocols as first-line therapy was associated with a significant improvement in median survival of 3.5 months (95% CI, 1.27 to 5.73 months; P = .0083). Conclusion Our results support the strategy of making these three active drugs available to all patients with advanced CRC who are candidates for such therapy to maximize OS. In addition, our findings suggest that, with the availability of effective salvage options, OS should no longer be regarded as the most appropriate end point by which to assess the efficacy of a palliative first-line treatment in CRC.

Background: Patients with multiple myeloma are frequently treated with bortezomib, a proteasome inhibitor, which is associated with treatment-related peripheral neuropathy. Older adults are at increased risk of falls compared to the general population, often leading to associated morbidity and mortality. While an association between peripheral neuropathy and falls in older adults is well-established, the relationship between bortezomib and falls in older multiple myeloma patients is unknown. Our primary aim was to determine if older patients with multiple myeloma treated with bortezomib as first-line therapy had an increased incidence of falls within the first 12 months after starting treatment. Our secondary aim was to assess the overall survival of patients who fell compared to those who did not among patients who lived more than 12 months after initiating treatment. Methods: We analyzed the SEER-Medicare database for all patients 65 years old or older diagnosed with multiple myeloma between 2007 and 2013 and were enrolled in fee-for-service Medicare part A, B and D plans. The patients' corresponding Medicare claims data were analyzed through 2014 for myeloma treatments, fall claims, and covariates of interest. The primary outcome was accidental falls (E880-E888) occurring between 14 days to 12 months after starting multiple myeloma treatment. First-line therapy was defined as any anti-myeloma treatment administered within 14 days of starting multiple myeloma treatment, with bortezomib treatment being the focal independent variable. Cox regression was performed to determine the relative risk of having a fall after controlling for other covariates. Patients who started bortezomib after first-line therapy were censored at time of bortezomib commencement. The survival analysis included only patients who survived more than 12 months of starting treatment to allow landmark analysis of falls in the first year. Results: Of 4,084 older adults with new multiple myeloma diagnoses undergoing first-line therapy, the median age was 75 (range 65-97) with 51% males. Bortezomib was used in first-line therapy for 2,052 (50%) patients, of which 157 (8%) patients experienced a fall within 12 months after starting treatment compared to 102 (5%) of patients not receiving bortezomib (p < 0.001). Bortezomib was associated with a 28% increase risk of falls (HR 1.29; 95% CI 1.00-1.65; p = 0.047). In multivariate analysis, bortezomib was not associated with an increased incidence of falls after controlling for age, gender, race, proxies for Charlson Comorbidity Index (CCI) and poor performance status, pre-existing peripheral neuropathy, falls within the 12 months prior to starting first-line myeloma treatment, depression, polypharmacy, and first-line treatment with lenalidomide (Table 1). Advancing age, history of fall(s), depression, and polypharmacy (defined as more than 10 unique prescription medications at initiation of first-line treatment), were all associated with an increased risk of falls, consistent with prior literature. In a landmark analysis of those who survived 12 months following the start of treatment, a fall was associated with a 26% increased risk of hazard for death (aHR 1.26; 95% CI 1.02-1.56; p = 0.033) after controlling for other covariates. The median OS of those with a fall was 35.7 months (95% CI 29.1-48.4) compared to 49.1 months (95% CI 47.1-52.8) for those without (p < 0.0001). Conclusion: In older adults with multiple myeloma, treatment with bortezomib was not associated with increased risk of a patient having a diagnostic code for falls. However, experiencing a fall within the year after starting treatment was associated with decreased overall survival. Limitations of the study include that the incidence of falls is likely underestimated in billing data, given prior data from our group showing a rate of self-reported falls of 26% in the year after diagnosis. Additional research, including prospective trials involving fall assessments, should be considered in older patients with multiple myeloma.
