Abstract In newly diagnosed multiple myeloma (MM) patients, the combination melphalan, prednisone and thalidomide (MPT) induces a fast tumor response with a high response rate, but evidence that this translate into improved outcome is limited. This multicenter trial compared the efficacy and the toxicity of oral MPT with oral melphalan and prednisone (MP) in previously untreated patients. From January 2002 to December 2004, we randomised 255 patients, who were older than 65 years of age (median age 72). Data analysis was performed on July 2005. The MPT regimen included oral melphalan (4 mg/m2 for 7 days) and prednisone (40 mg/m2 7 days) for six four week cycles plus thalidomide (100 mg per day continuously until any sign of relapse or progressive disease) The MP regimen was as MPT without thalidomide. Patients who were not assigned to receive thalidomide were permitted to cross over to receive thalidomide after relapse or disease progression. Patients treated with MPT experienced higher response rates and a longer time to progression (primary end points) than patients who did not receive thalidomide. The overall response rate was 76% for MPT and 48% for MP alone (P<0.0001), and the near complete response rates were 28% and 7%, respectively (P<0.0001). Median progression free survival in the MPT and in the MP groups was 33 months and 14 months, respectively (hazard ratio, 0.47; P<0.001). MPT increase median progression free survival by almost 19 months. The 2-yr survival rate was 82% in MPT patients and 65% in MP patients (hazard ratio, 0.68; P=0.2). In MPT group, 33 patients did not complete the 6 courses because of progression disease (9), toxicity (16), death (2), and withdrawal of consent or lost to follow-up (6). In MP group, 32 patients did not complete the 6 courses because of progression disease (19), toxicity (3), death (3), and withdrawal of consent or lost to follow-up (7). By looking at those patients who completed the assigned 6 cycles in both arms, the 2-yr survival rate was 90% in MPT patients and 71% in MP patients, the difference was statistically significant (hazard ratio, 0.39; P<0.01). Grade 3 or 4 adverse events were reported in 49% of patients treated with MPT and in 25% of those treated with MP: they included thromboembolism (12% versus 2% of patients), infections (10% versus 1%), peripheral neuropathy (10% versus 1%), and hematologic toxicity (22% versus 25%) respectively. In the first 64 patients who received MPT, grade 3–4 adverse events were reported in 58% of patients. In the last 65 MPT patients, the incidence of grade 3–4 adverse events was 40%. By comparing the first cohort with the second one, thromboembolism dropped from 22% to 3% (P<0.01) and neurotoxicity from 13% to 8% (P=NS), respectively. The oral MPT was superior to the standard MP in patients with newly diagnosed myeloma. The adequate mangement of side effects reduced toxicity.

Purpose Bortezomib-melphalan-prednisone (VMP) has improved overall survival in multiple myeloma. This randomized trial compared VMP plus thalidomide (VMPT) induction followed by bortezomib-thalidomide maintenance (VMPT-VT) with VMP in patients with newly diagnosed multiple myeloma. Patients and Methods We randomly assigned 511 patients who were not eligible for transplantation to receive VMPT-VT (nine 5-week cycles of VMPT followed by 2 years of VT maintenance) or VMP (nine 5-week cycles without maintenance). Results In the initial analysis with a median follow-up of 23 months, VMPT-VT improved complete response rate from 24% to 38% and 3-year progression-free-survival (PFS) from 41% to 56% compared with VMP. In this analysis, median follow-up was 54 months. The median PFS was significantly longer with VMPT-VT (35.3 months) than with VMP (24.8 months; hazard ratio [HR], 0.58; P < .001). The time to next therapy was 46.6 months in the VMPT-VT group and 27.8 months in the VMP group (HR, 0.52; P < .001). The 5-year overall survival (OS) was greater with VMPT-VT (61%) than with VMP (51%; HR, 0.70; P = .01). Survival from relapse was identical in both groups (HR, 0.92; P = .63). In the VMPT-VT group, the most frequent grade 3 to 4 adverse events included neutropenia (38%), thrombocytopenia (22%), peripheral neuropathy (11%), and cardiologic events (11%). All of these, except for thrombocytopenia, were significantly more frequent in the VMPT-VT patients. Conclusion Bortezomib and thalidomide significantly improved OS in multiple myeloma patients not eligible for transplantation.

PURPOSE Melphalan flufenamide (melflufen) is a first-in-class peptide-drug conjugate that targets aminopeptidases and rapidly and selectively releases alkylating agents into tumor cells. The phase II HORIZON trial evaluated the efficacy of melflufen plus dexamethasone in relapsed and refractory multiple myeloma (RRMM), a population with an important unmet medical need. PATIENTS AND METHODS Patients with RRMM refractory to pomalidomide and/or an anti-CD38 monoclonal antibody received melflufen 40 mg intravenously on day 1 of each 28-day cycle plus once weekly oral dexamethasone at a dose of 40 mg (20 mg in patients older than 75 years). The primary end point was overall response rate (partial response or better) assessed by the investigator and confirmed by independent review. Secondary end points included duration of response, progression-free survival, overall survival, and safety. The primary analysis is complete with long-term follow-up ongoing. RESULTS Of 157 patients (median age 65 years; median five prior lines of therapy) enrolled and treated, 119 patients (76%) had triple-class–refractory disease, 55 (35%) had extramedullary disease, and 92 (59%) were refractory to previous alkylator therapy. The overall response rate was 29% in the all-treated population, with 26% in the triple-class–refractory population. In the all-treated population, median duration of response was 5.5 months, median progression-free survival was 4.2 months, and median overall survival was 11.6 months at a median follow-up of 14 months. Grade ≥ 3 treatment-emergent adverse events occurred in 96% of patients, most commonly neutropenia (79%), thrombocytopenia (76%), and anemia (43%). Pneumonia (10%) was the most common grade 3/4 nonhematologic event. Thrombocytopenia and bleeding (both grade 3/4 but fully reversible) occurred concomitantly in four patients. GI events, reported in 97 patients (62%), were predominantly grade 1/2 (93%); none were grade 4. CONCLUSION Melflufen plus dexamethasone showed clinically meaningful efficacy and a manageable safety profile in patients with heavily pretreated RRMM, including those with triple-class–refractory and extramedullary disease.

Purpose Until recently, melphalan and prednisone were the standards of care in elderly patients with multiple myeloma. The addition of thalidomide to this combination demonstrated a survival benefit for patients age 65 to 75 years. This randomized, placebo-controlled, phase III trial investigated the efficacy of melphalan and prednisone plus thalidomide in patients older than 75 years with newly diagnosed myeloma. Patients and Methods Between April 2002 and December 2006, 232 previously untreated patients with myeloma, age 75 years or older, were enrolled and 229 were randomly assigned to treatment. All patients received melphalan (0.2 mg/kg/d) plus prednisone (2 mg/kg/d) for 12 courses (day 1 to 4) every 6 weeks. Patients were randomly assigned to receive 100 mg/d of oral thalidomide (n = 113) or placebo (n = 116), continuously for 72 weeks. The primary end point was overall survival. Results After a median follow-up of 47.5 months, overall survival was significantly longer in patients who received melphalan and prednisone plus thalidomide compared with those who received melphalan and prednisone plus placebo (median, 44.0 v 29.1 months; P = .028). Progression-free survival was significantly prolonged in the melphalan and prednisone plus thalidomide group (median, 24.1 v 18.5 months; P = .001). Two adverse events were significantly increased in the melphalan and prednisone plus thalidomide group: grade 2 to 4 peripheral neuropathy (20% v 5% in the melphalan and prednisone plus placebo group; P < .001) and grade 3 to 4 neutropenia (23% v 9%; P = .003). Conclusion This trial confirms the superiority of the combination melphalan and prednisone plus thalidomide over melphalan and prednisone alone for prolonging survival in very elderly patients with newly diagnosed myeloma. Toxicity was acceptable.

Objective. To investigate the efficacy and safety of the treatment of the newly diagnosed multiple myeloma (MM) patients with the therapy of subcutaneous (subQ) administration of bortezomib and dexamethasone plus thalidomide (VTD) regimen.Methods. A total of 60 newly diagnosed MM patients were analyzed. 30 patients received improved VTD regimen (improved VTD group) with the subQ injection of bortezomib and the other 30 patients received conventional VTD regimen (VTD group).The efficacy and safety of two groups were analyzed retrospectively.Results. The overall remission (OR) after eight cycles of treatment was 73.3% in the VTD group and 76.7% in the improved VTD group (P>0.05). No significant differences in time to 1-year estimate of overall survival (72% versus 75%,P=0.848) and progression-free survival (median 22 months versus 25 months;P=0.725) between two groups. The main toxicities related to therapy were leukopenia, neutropenia, thrombocytopenia, asthenia, fatigue, and renal and urinary disorders. Grade 3 and higher adverse events were significantly less common in the improved VTD group (50%) than VTD group (80%,P=0.015).Conclusions. The improved VTD regimen by changing bortezomib from intravenous administration to subcutaneous injection has noninferior efficacy to standard VTD regimen, with an improved safety profile and reduced adverse events.

Abstract Background: The activity of V in myeloma was first described in the 1970’s. Although Phase II data suggest that V demonstrates single agent activity, subsequent reports have questioned its role. Due to these conflicting results, we conducted a subanalysis investigating the effect of V dose in the phase II DVd-T regimen that we have previously reported (Agrawal et al ASH 2003). We evaluated the effects of V dose on progression free survival (PFS) and overall survival (OS) in newly diagnosed and relapsed/refractory patients treated with DVd-T. Patients and Methods: As previously reported, this Phase II study enrolled 102 patients with newly diagnosed or relapsed/refractory multiple myeloma with evidence of end organ damage. DVd-T was administered as previously reported. After best response, patients were maintained on prednisone 50mg every other day and the maximum tolerated dose of thalidomide until disease progression. For patients experiencing grade 1 neuropathy, V was reduced by 25%, and for grade 2, by 50%. Patients developing grade 3/4 neuropathy had V discontinued and thalidomide suspended until toxicity decreased by at least one grade. Univariate analyses were conducted to assess the effect of V dose reduction or elimination on PFS and OS. Multivariate analyses were performed to adjust for the impact of age, platelet count, stage, quality of response (CR or near CR versus SD or PR), and thalidomide dose. Results: Trial included 53 newly diagnosed and 49 relapsed/refractory patients. Median age was 62.9 years. 59% had stage 3 or 4 disease. 37% had abnormal cytogenetics. Median beta-2 microglobulin was 4.1. Overall response rate of 87% was seen in newly diagnosed patients (36% achieved CR; 13% near CR; 38% PR; 8% SD; 6% PD). In the relapsed/refractory patients, overall response rate of 87% was achieved (21% achieved CR; 26% near CR; 40% PR; 13% SD). Median follow up was 28.1 months. Median PFS for the newly diagnosed group was 28.2 months and 15.5 for the relapsed/refractory group. Median OS was 39.9 months for the relapsed/refractory group. After 50 months of follow-up for the newly diagnosed group, median OS has not been reached. In total, 464 cycles were administered, of which 225 were given with full dose V and 242 with reduced dose or eliminated V. Grade 3/4 neuropathy occurred in 22 patients. Univariate analysis revealed that reducing or eliminating V had a significant positive effect on PFS and OS (p = 0.0002 and 0.02 respectively). Multivariate analysis adjusting for age at start of study, platelet count, stage, quality of response [CR or near CR versus SD or PR], and thalidomide dose, similarly found that reducing or eliminating the dose of V had a significant positive effect (p = 0.0121) on PFS. However, multivariate analysis did not reveal the same effect on OS (p = 0.11). Conclusions: This subanalysis suggests that the use of full dose V in the DVd-T regimen may have a negative effect on PFS. The exact mechanism by which V affects PFS is not clear. Studies are now on-going investigating this regimen without V. Figure Figure

Abstract Background: Mantle cell lymphoma (MCL) is an unfavorable subtype of B-cell non-Hodgkin lymphoma characterized by median progression-free survival (PFS) and median overall survival (OS) of only 1.5 and 3–4 years respectively. Although high-dose therapy and an autotransplant may prolong OS, it does not result in a long-term disease free survival. Therefore, there is a need for novel therapeutic approaches for this entity. Methods: We conducted a single-arm phase II study in subjects with newly-diagnosed MCL to assess efficacy and safety of a novel intensive regimen R-MACLO-IVAM-T, a modification of a protocol designed by Magrath et al (JCO1996;14:925). The study size of 22 patients was based on precision of a two-sided 95% confidence interval for the 18-month progression free survival rate. Eligible subjects had a confirmed diagnosis of MCL using WHO criteria, age 18–75 years, ECOG PS ≤ 2, adequate organ function and no history of HIV or prior cancer. Lymphoma extent at presentation was assessed by standard staging procedures as well as esophagogastroduodenoscopy and colonoscopy. Prior to initiating thalidomide maintenance, subjects were enrolled in the STEPS® program. Cycle 1 consisted of R-MACLO: rituximab 375 mg/m2 IV on day 1, doxorubicin 45 mg/m2 IV on day 1, cyclophosphamide 800 mg/m2 IV on day 1 and 200 mg/m2/day on days 2–5, vincristine 1.5 mg/m2 on days 1 and 8 capped to 2mg, methotrexate 1.2 g/m2 IV on day 10 over 1 hour followed by 5.52 g/m2 IV over 23 hours followed by leucovorin 36 hours later. G-CSF was begun on day 13. When the ANC was >1.5×109/L, cycle 2 with R-IVAM was begun: rituximab 375 mg/m2 IV day 1, cytarabine 2 g/m2 IV every 12 hours on days 1 and 2, etoposide, 60 mg/m2 on days 1–5 and ifosfamide 1.5 g/m2 on days 1–5 with mesna. Fourteen days after ANC recovery from cycle 2, cycles 3 and 4 were given in identical fashion to 1 and 2. Four weeks after ANC recovery from cycle 4, subjects were re-staged and responses were assessed by standard criteria. Subjects achieving CR at the end of therapy received thalidomide 200 mg/day until MCL relapse or intolerable toxicity. Results: Accrual started in 4/2004 and ended in 3/2008 when the planned 22 subjects were enrolled. All subjects were evaluable for toxicity and 21 were evaluable for response. Median age was 56.5 years (range 39–73). All subjects had at least stage 3 disease with bone marrow involvement in 19 and gastrointestinal involvement in 10. Distribution according to IPI: 0–1 factor, 3; 2 factors, 8; 3 factors, 8; and 4 factors, 3. Twenty subjects had diffuse variant and 2 had blastic variant. Nineteen subjects completed all 4 cycles of therapy; treatment was stopped in 2 subjects after 2 and 3 cycles respectively, and one subject died during the first cycle. Of the 21 subjects completing 2 cycles of therapy, 20 achieved CR and one PR. Two subjects relapsed at 9 and 33 months respectively, while 19 remain relapse free after median follow-up of 25 months (range 5–51). With a total follow-up of 545 months, the estimated relapse rate is 4.4 per 100 patients per year. There were two deaths: 1 from sepsis on cycle 1 day 8 and the other in CR at 38 months from non-small cell lung cancer diagnosed 19 months after MCL. Common severe toxicities were grade 3–4 neutropenia, thrombocytopenia and anemia in 33%, 19% and 17% of R-MACLO cycles and in 50%, 88% and 68% of R-IVAM cycles respectively. There were 14 bacteremias in 82 cycles, 12 of which were after R-IVAM therapy. Six episodes of reversible grade 1–2 renal toxicity occurred after methotrexate. The thalidomide maintenance dose was reduced in 6 subjects due to grade 3–4 neutropenia and reduced or stopped in 8 subjects because of grade 3–4 peripheral neuropathy. Patients remain under follow-up for relapse and survival. Conclusions: R-MACLO-IVAM-T results in a high overall response rate of 100% (95% CR and 5% PR) and a low relapse rate. At a median follow-up of 25 months, median PFS and OS were not reached. The 2-year actuarial PFS of 94% compares favorably with previously reported 2-year actuarial PFS of 40% and 67% for CHOP-like regimens without and with upfront bone marrow transplantation (Blood2005;105: 2677). The contribution of thalidomide maintenance to this outcome requires additional study. A multicenter clinical trial is suggested.

Abstract Background: In newly diagnosed myeloma patients the combination of bortezomib with melphalan-prednisone (VMP) was superior to MP. In relapsed-refractory patients the 4 drug combination of bortezomib-melphalan-prednisone-thalidomide (VMPT) induced a high proportion of complete responses (CR). Methods: Newly diagnosed myeloma patients (N=393) older than 65 years, from 58 centers in Italy, were randomly assigned to receive VMPT (N=193) or VMP (N=200). Initially, patients were treated with nine 6-week cycles of VMPT (bortezomib 1.3 mg/m2 days 1,4,8,11,22,25,29,32 in cycles 1–4 and days 1,8,22,29 in cycles 5–9; melphalan 9 mg/m2 days 1–4; prednisone 60 mg/m2 days 1–4 and thalidomide 50 mg days 1–42, followed by bortezomib 1.3 mg/m2 every 15 days and thalidomide 50 mg/day as maintenance) or VMP (bortezomib, melphalan and prednisone at the same doses and schedules previously described without maintenance). In March 2007, the protocol was amended: both VMPT and VMP schedules were changed to nine 5-week cycles and bortezomib schedule was modified to weekly administration (bortezomib 1.3 mg/m2 days 1,8,15,22 in cycles 1–9). Primary end-point was progression-free survival (PFS). Results: Patient characteristics were similar in both groups: median age was 71 years, 23% of patients were aged > 75 years. Patients who received at least 1 cycle were evaluated: 152 patients for VMPT (62 received bortezomib bi-weekly infusion and 90 weekly infusion) and 152 patients for VMP (62 received bortezomib bi-weekly infusion and 90 weekly infusion). Data were analyzed in intention-to-treat. The very good partial response (VGPR) rate was higher in the VMPT group (55% versus 42%, p=0.02), including a CR rate of 31% in the VMPT group and 16% in the VMP group (p=0.003). In the subgroup treated with weekly infusion of bortezomib, VGPR was 59% for VMPT and 37% for VMP (p=0.004), including 28% CR for VMPT and 10% for VMP (p=0.004). Subgroup analyses did not show any statistical difference between responses and either age, B2-microglobulin or chromosomal abnormalities, such as del13, t(4;14), t(14;16) and del17. After a median follow-up of 13.6 months, the 2-year PFS was 83.9% in the VMPT group and 75.7% in the VMP group (HR=0.73, 95% CI 0.38–1.42, p=0.35). In patients who received weekly infusion of bortezomib, the 2-year PFS was 86.8% in the VMPT group and 78.1% in the VMP group (HR=0.65, 95% CI 0.24–1.8, p=0.41). In patients who achieved CR after induction, the 2-year PFS was 100% for VMPT and 79% for VMP (p=0.02). The 3-year overall survival (OS) was 89.5% in the VMPT group and 88.7% in the VMP group (HR=1.02, 95% CI 0.43–2.46, p=0.96). The incidence of grade 3–4 adverse events (AEs) was similar in both groups. In the VMPT patients and in the VMP patients, the more frequent AEs were neutropenia (36% vs 31%), thrombocytopenia (20% vs 19%), peripheral neuropathy (18% vs 12%), infections (14% vs 10%), and gastrointestinal complications (7% vs 8%), respectively. The weekly infusion of bortezomib significantly decreased the incidence of grade 3–4 peripheral neuropathy (9% for VMPT and 3% for VMP). Conclusion: VMPT is superior to VMP in terms of response rates. Longer follow-up is needed to assess their effects on PFS and OS. The weekly infusion of bortezomib significantly reduced the incidence of grade 3–4 peripheral neuropathy without influencing outcome. Table.

The Impact

Abstract Introduction : To date, the ELN recommendation and NCCN guidelines are the principle mile stones to follow up the treatment response and to make the decision of TKIs switching. However, in real life practice, many factors influence changing the real switching date from the date had an indication. This study aims to analyze the impact of early switching to second line TKI, nilotinib, in real life practice, for the CML patients who failed, had sub-optimal response or were intolerant to imatinib. Methods : This prospective study was conducted through 7 medical centers in Thailand between 1st of September 2009 and 31st of August 2011. Adult CML patients of age ≥ 18 years old, in chronic and accelerated phase, who had failure, suboptimal response or intolerance to imatinib, based on ELN 2009 guideline, were included and were eligible with nilotinib 400 mg twice daily. Prospective data collection for 24 months of each patient was performed. The main objective was to identify the impact of early switching to nilotinib on major molecular response (MMR). The other objectives were to observe the efficacy of nilotinib including overall survival, progression free survival and the safety. The survival results were presented as Kaplan-Meier survival curves. For the comparison of the treatment groups, the Kaplan-Meier estimator with the corresponding log-rank test for equality of survivor functions across treatment group was applied. Results : The final 108 cases were analysed. The median age was 47 (17-79) years with the proportion of male to female of 1.4:1 respectively. The median duration of the prior imatinib treatment was 18 months (2-142 months). The median duration between the date of indication and the date of real switching was 3.1 months (0-62.8 months) with 50% changing less than 3 months, 26.9% between 3 months and 12 months, and 23.1% changing longer than 12 months. The indication of switching included 63.6% failure to imatinib, 29% intolerance to imatinib and 7.4% suboptimal to imatinib. On the nilotinib switching, 70.4% completed 24 months follow-up, and 29.6% discontinued treatment mostly because of unsatisfactory results or adverse events. Evaluation was made every 3 months based on 2009 ELN recommendation. At 3 months, 57%, 20%, and 8% of the patients achieved CHR, CCyR and MMR, respectively. Those who did not achieve CHR at 3 months never achieved MMR, while 86 % of those who achieved CCyR at 3 months achieved MMR. All CML achieving MMR at 3 months had sustained MMR throughout the study period (24 months). Imatinib suboptimal response had better outcome than imatinib failure and imatinib intolerance groups. A preliminary analysis of BCR-ABL mutation was performed on 90 cases, and mutations were found on 21 cases. Two of them were T315I which were excluded from the study. The cases with mutation had poorer response to treatment than those without mutation. There was one case with initial G250E mutation developing T315I mutation after treatment with nilotinib. At 24 months, one case progressed to accelerated phase and 3 cases progressed to blastic transformation. The 2-year overall survival and 2-year progression-free survival and were 98.9% and 96.9% (figure 1 and 2), respectively. The interquatile analysis was done to identify the groups of cumulative MMR according to the duration between the date of indication and the date of real switching to nilotinib. The patients who switched to nilotinib within 12 months after date of indication could have a greater chance to achieved MMR than those who switched treatment later than 12 months (p(log-rank) = 0.002) (figure 3). Skin rash, musculoskeletal pain, and infection were the three most common non-hematologic adverse events, However, most of them were grade 1-2, except for 4 cases with grade 3-4 infections. Grade 3-4 hematologic adverse events included thrombocytopenia (12%), neutropenia (11%), anemia (5%) and leucopenia (4%), and most of them were manageable. Although biochemical abnormalities were commonly found, most of them were mild. Conclusions : Nilotinib, as a second line treatment showed excellent efficacy and tolerability. Indication for nilotinib treatment, initial mutation status and depth of response at 3 months after treatment can predict outcomes of the patients. However, the patients will have a greater chance to achieve MMR if they switched to nilotinib within 12 months after the date of indication for changing.

Continuous lenalidomide-dexamethasone (Rd)-based regimens are among the standards of care in transplant-ineligible newly diagnosed multiple myeloma (NDMM) patients. The oral proteasome inhibitor ixazomib is suitable for continuous dosing, with predictable, manageable toxicities. In the double-blind, placebo-controlled TOURMALINE-MM2 trial transplant-ineligible NDMM patients were randomized to ixazomib 4 mg (n = 351) or placebo (n = 354) plus Rd. After 18 cycles, dexamethasone was discontinued; treatment continued using reduced-dose ixazomib (3 mg) and lenalidomide (10 mg) until progression/toxicity. The primary endpoint was progression-free survival (PFS). Median PFS (mPFS) was 35.3 vs 21.8 months with ixazomib-Rd vs placebo-Rd, respectively (hazard ratio [HR], 0.830; 95% confidence interval, 0.676-1.018; P = .073; median follow-up, 53.3 and 55.8 months). Complete (26% vs 14%; odds ratio [OR], 2.10; P &lt; .001) and ≥ very good partial response (63% vs 48%; OR, 1.87; P &lt; .001) rates were higher with ixazomib-Rd vs placebo-Rd. In a prespecified high-risk cytogenetics subgroup, mPFS was 23.8 vs 18.0 months (HR, 0.690; P = .019). Overall, treatment-emergent adverse events (TEAEs) were mostly grade 1/2. With ixazomib-Rd vs placebo-Rd, 88% vs 81% of patients experienced grade ≥3 TEAEs, 66% vs 62% serious TEAEs, and 35% vs 27% TEAEs resulting in regimen discontinuation; 8% vs 6% died on study. Ixazomib-Rd is a feasible option for certain patients who can benefit from an all-oral triplet combination. This trial was registered at www.clinicaltrials.gov (#NCT01850524).

46 Background: We previously reported results of a randomized study showing that CX is equally active to ECX in terms of progression-free survival (PFS) (Yun et al. Eur J Cancer. 2010). Here we report updated overall survival (OS) results with an additional 12 months' follow-up. Methods: Ninety-one chemotherapy-naïve patients with histologically-confirmed, measurable AGC were randomized to receive CX (cisplatin 75 mg/m2 iv on day 1 and capecitabine 1,000 mg/m2 bid po on days 1-14, n=45) or ECX (epirubicin 50 mg/m2 plus CX, n=44) every 3 weeks. After CX or ECX had failed, second-line chemotherapy (SLC) was recommended for all patients if their performance status was preserved. Results: Treatment duration was similar for both arms (4.4 for CX v 4.2 months for ECX). There was no relevant difference in the occurrence of overall grade 3 or 4 toxicities between the CX and ECX arms (80% v 78%, respectively; p=0.516). However, none in the CX and 12% in the ECX arm discontinued treatment because of toxicity. There were no significant differences in therapeutic efficacy between CX and ECX with respect to the response rate (38% v 37%, respectively), PFS (6.4 v 6.5 months), as well as OS (12.7 v 13.8 months; p=0.51). After failure, 60% of patients (26 CX and 28 ECX patients) received SLC. However, OS was not differed whether a patient was treated with SLC or not (13.1 v 11.2 months; p=0.94). Conclusions: The present analysis confirms previous findings that both CX and ECX appear to be comparatively active as first-line chemotherapy for AGC. Furthermore, the role of SLC in AGC warrants further evaluation. No significant financial relationships to disclose.
