PURPOSE The double-blind, randomized, placebo-controlled phase III iNNOVATE study showed sustained efficacy of ibrutinib-rituximab in Waldenström's macroglobulinemia (WM). Here, we present the final analysis from iNNOVATE. METHODS Patients had confirmed symptomatic WM, either previously untreated or previously treated; patients with prior rituximab had at least a minor response to their last rituximab-based regimen. Patients were randomly assigned to once-daily ibrutinib 420 mg plus rituximab or placebo plus rituximab (n = 75 per arm). The primary end point was progression-free survival (PFS). Secondary end points included response rate, time to next treatment, hemoglobin improvement, overall survival, and safety. RESULTS With a median follow-up of 50 (range, 0.5-63) months, median (95% CI) PFS was not reached (57.7 months to not evaluable) with ibrutinib-rituximab versus 20.3 months (13.0 to 27.6) with placebo-rituximab (hazard ratio, 0.250; P < .0001). PFS benefit was regardless of prior treatment status, MYD88 and CXCR4 mutation status, or key patient characteristics. Higher response rates (partial response or better) were observed with ibrutinib-rituximab (76% v 31% with placebo-rituximab; P < .0001) and were sustained over time. Median time to next treatment was not reached with ibrutinib-rituximab versus 18 months with placebo-rituximab. More patients receiving ibrutinib-rituximab versus placebo-rituximab had sustained hemoglobin improvement (77% v 43%; P < .0001). Median overall survival was not reached in either arm. Ibrutinib-rituximab maintained a manageable safety profile; the prevalence of grade ≥ 3 adverse events of clinical interest generally decreased over time. CONCLUSION In the final analysis of iNNOVATE with a median follow-up of 50 months, ibrutinib-rituximab showed ongoing superiority across clinical outcomes in patients with WM regardless of MYD88 or CXCR4 mutation status, prior treatment, and key patient characteristics.

Purpose This final analysis of the phase III VISTA trial (Velcade As Initial Standard Therapy in Multiple Myeloma: Assessment With Melphalan and Prednisone) was conducted to determine whether the overall survival (OS) benefit with bortezomib-melphalan-prednisone (VMP) versus melphalan-prednisone (MP) in patients with myeloma who were ineligible for transplantation was maintained after 5 years of follow-up and to explore the risk of second primary malignancies. Patients and Methods In all, 682 patients received up to nine 6-week cycles of VMP or MP and were then observed every 12 weeks or less. Data on second primary malignancies were collected by individual patient inquiries at all sites from 655 patients. Results After median follow-up of 60.1 months (range, 0 to 74 months), there was a 31% reduced risk of death with VMP versus MP (hazard ratio [HR], 0.695; P < .001; median OS 56.4 v 43.1 months). OS benefit with VMP was seen across prespecified patient subgroups (age ≥ 75 years, stage III myeloma, creatinine clearance < 60 mL/min). Sixty-three percent of VMP patients and 73% of MP patients had received subsequent therapy. Time to next therapy (median, 30.7 v 20.5 months; HR, 0.557; P < .001) was longer with VMP than with MP. Among patients who received subsequent therapies, survival from start of subsequent therapy was similar following VMP (median, 28.1 months) or MP (median, 26.8 months; HR, 0.914). Following VMP/MP, incidence proportions of hematologic malignancies (1%/1%) and solid tumors (5%/3%) and exposure-adjusted incidence rates (0.017/0.013 per patient-year) were similar and were consistent with background rates. Conclusion VMP resulted in a significant reduction in risk of death versus MP that was maintained after 5 years' follow-up and despite substantial use of novel-agent-based salvage therapies. There is no emerging safety signal for second primary malignancies following VMP.

Abstract Introduction: Lenalidomide (Len), an analog of thalidomide (Thal) is a novel, oral, immunomodulatory agent that is effective against multiple myeloma (MM). In 2 prospective, randomized, double-blind, placebo-controlled phase III trials, Len with dexamethasone (Dex) induced a significantly higher overall response (OR) rate and complete remission (CR) rate, as well as longer time-to-progression (TTP) in comparison with Dex alone. Here, we investigate the long-term overall survival (OS) with Len/Dex. Methods: We evaluated the pooled results from both randomized trials (MM-009, MM-010) of 704 patients who had relapsed or refractory MM, without prior resistance to Dex, who received either Len (25 mg daily for 3 weeks every 4 weeks), or placebo. Dex was given at 40 mg on days 1–4, 9–12, 17–20 every 4 weeks for 4 cycles. From cycle 5 onwards, Dex was given at 40 mg on days 1–4 only. Response rate and TTP are based on data obtained before unblinding (June 2005 [MM-009] and August 2005 [MM-010]). Follow-up data on OS were obtained up to January 2007. Forty-seven percent of patients who received placebo/Dex crossed over to receive Len +/− Dex. Results: Of 704 patients, 353 were treated with Len/Dex and 351 with Dex alone. Baseline characteristics were well balanced between patients receiving Len/Dex and those receiving Dex alone. Median TTP, OR, and CR were significantly improved in patients treated with Len/Dex compared with Dex alone (Table). Of patients who progressed on Dex alone prior to unblinding, or were found to be receiving Dex alone after unblinding, 47% crossed over to Len +/− Dex. Despite these patients crossing over to Len +/− Dex at progression or at the time of unblinding, the OS was significantly improved in patients treated with Len/Dex compared with Dex alone (hazard ratio 1.295; 95% confidence interval 1.040–1.614; p=0.02). Median OS in the Len/Dex group was 35 months and 31 in the Dex alone group (p<0.05). Median OS was also significantly longer with Len/Dex compared with Dex alone in patients with more than 1 prior therapy (32.4 months versus 27.3 months, p<0.05). Similar median OS was observed with Len/Dex and Dex alone in patients with 1 prior therapy (median OS not yet reached and 35.3 months, p=0.24). Conclusion: With increased follow-up and despite cross-over, patients treated first with Len/Dex had significantly improved OS compared with those treated with Dex alone.

268 Background: KEYNOTE-240 (NCT02702401) examined the anti-PD-1 antibody pembro and demonstrated improvement in OS and PFS vs pbo in pts with aHCC previously treated with sorafenib. However, the study did not meet prespecified statistical significance criteria for OS and PFS. Median OS (final analysis) was 13.9 mo for pembro vs 10.6 mo for pbo (HR 0.781; 95% CI 0.611-0.998). At the first interim analysis when PFS and ORR were prespecified to be tested, median PFS was 3.0 mo for pembro vs 2.8 mo for pbo (HR 0.775; 95% CI 0.609-0.987) and ORR was 16.9% (CR, n = 3) for pembro and 2.2% (CR, n = 0) for pbo. AEs were consistent with the known safety profile of pembro. Longer-term data from KEYNOTE-240 after ~1.5 years of additional follow-up are reported. Methods: Adults with confirmed aHCC who experienced failure (progression or intolerance) to sorafenib therapy were randomized 2:1 to pembro 200 mg IV Q3W + best supportive care (BSC) or pbo + BSC for ≤35 cycles or until confirmed progression/unacceptable toxicity, pt withdrawal of consent, or investigator decision. Dual primary end points were OS and PFS, assessed by blinded independent central review (BICR) per RECIST v1.1. Secondary end points included ORR, DOR, DCR, TTP (all assessed by BICR per RECIST v1.1), and safety. Results: Of 413 pts, 278 were randomized to pembro and 135 to pbo. As of July 13, 2020, median time from randomization to data cutoff was 39.6 mo (range 31.7-48.8) for pembro and 39.8 mo (31.7-47.8) for pbo. Median OS was 13.9 mo (95% CI 11.6-16.0) for pembro and 10.6 mo (8.3-13.5) for pbo (HR 0.771; 95% CI 0.617-0.964). Estimated OS rates at 24 and 36 mo for pembro and pbo were 28.8% and 20.4% and 17.7% and 11.7%, respectively. Median PFS was 3.3 mo (95% CI 2.8-4.1) for pembro and 2.8 mo (1.6-3.0) for pbo (HR 0.703; 95% CI 0.559-0.885). Estimated PFS rate at 24 mo was 11.8% for pembro and 4.8% for pbo. ORR was 18.3% (95% CI 14.0-23.4) for pembro and 4.4% (1.6-9.4) for pbo. Median time to response was 2.7 mo (95% CI 1.2-16.9) for pembro and 2.9 mo (1.1-6.9) for pbo. Median DOR was 13.9 mo (range 1.5+ to 41.9+) for pembro and 15.2 mo (2.8-21.9) for pbo; 45.1% of responders in pembro arm and 33.3% of responders in pbo arm had DOR ≥12 mo. DCR was 61.9% for pembro and 53.3% for pbo. Best overall responses were 10 CR, 41 PR, 121 SD, and 85 PD for pembro and 0 CR, 6 PR, 66 SD, and 54 PD for pbo. The median TTP was 4.0 mo (95% CI 2.8-5.3) for pembro and 2.8 mo (1.6-3.0) for pbo. No new or unexpected AEs occurred. The frequency of sponsor-assessed immune-mediated hepatitis events did not increase with additional follow-up. There continued to be no HBV or HCV viral flare events. Conclusions: In previously treated pts with aHCC, improvement in OS and PFS was maintained over time with pembro vs pbo, and the safety profile remained consistent over time. These data support the benefit:risk profile of pembro. Clinical trial information: NCT02702401.

204 Background: Previous results from the ATTRACTION-3 phase 3 trial demonstrated a significant improvement in overall survival and a favorable safety profile compared with taxane chemotherapy (CT) in previously-treated ESCC patients. To our knowledge, no long-term efficacy and safety data of this immune checkpoint inhibitor has been reported in ESCC. Herein, we report the three-year survival data of Nivo in ESCC. Methods: In ATTRACTION-3, 419 patients with unresectable advanced or recurrent ESCC refractory or intolerant to 1 prior fluoropyrimidine/platinum-based CT were randomized in a 1:1 ratio to receive Nivo (N = 210) or the investigator’s choice of CT (paclitaxel or docetaxel) (N = 209) until disease progression or unacceptable toxicity. The primary endpoint was overall survival (OS). A subgroup analysis of OS according to the best overall response (BOR) was performed. The onset of treatment-related adverse events of special interest over time in the Nivo arm was also evaluated. Results: As of data cut-off on 25 May 2020, 3 years after the last patient was enrolled, the median OS (mOS) was 10.91 months with Nivo versus 8.51 months with CT [hazard ratio (HR) 0.79; 95% confidence interval (CI) 0.64-0.97]. The OS rates of patients with Nivo and CT were 20.2 % and 13.5 % at 24 months, and 15.3% and 8.7% at 36 months, respectively. In the subgroup analysis of OS by BOR, mOS in CR/PR patients were 19.91 and 15.41 months (HR 0.84, 95%CI 0.46-1.54) and that in SD patients were 17.38 and 9.36 months (HR 0.45, 95%CI 0.26-0.78) in the Nivo and CT arm, respectively. Furthermore, mOS in PD patients were 10.91 and 6.18 months (HR 0.56, 95%CI 0.33-0.95) in the Nivo and CT arm, respectively. No new safety signals were detected during the three-year follow-up. Time to onset of the event of special interest was within the range of events previously observed in other indications. Conclusions: At three-year follow up, Nivo continued to show improved OS over CT in pretreated patients with advanced ESCC patients. Nivo showed a longer mOS than CT regardless of BOR. During the three-year follow-up, no new safety signals were observed. Clinical trial information: NCT02569242.

516 Background: Current guidelines recommend GnRH agonist (GnRHa) use during chemotherapy (CT) as a strategy to reduce the risk of premature ovarian insufficiency (POI) in premenopausal patients with early breast cancer (EBC). However, no long-term safety data are available raising some concerns on concurrent use of GnRHa during CT in patients with hormone receptor-positive disease. In addition, there is no evidence on the protective role of this strategy in patients with germline BRCA mutations ( mBRCA). Here, we report the final analysis of the PROMISE-GIM6 phase III randomized study, the largest trial addressing the role of GnRHa use during CT in premenopausal EBC patients (Del Mastro et al, JAMA 2011 & Lambertini et al, JAMA 2015). Methods: From October 2003 to January 2008, 281 premenopausal patients aged 18 to 45 years with stage I-III EBC candidates for (neo)adjuvant CT were randomized to receive CT alone or combined with the GnRHa triptorelin. Primary endpoint was incidence of CT-induced POI (defined as amenorrhea and post-menopausal FSH/estradiol levels 1 year following CT). This final analysis reports on post-treatment pregnancies, disease-free survival (DFS) and overall survival (OS). An exploratory descriptive analysis in mBRCA patients is also reported. (ClinicalTrial.gov: NCT00311636) Results: Of the 281 randomized patients (CT+GnRHa arm = 148; CT alone arm = 133), 80% had hormone receptor-positive disease. At the time of this final analysis, 38 (13.5%) patients were lost to follow-up. Median follow-up was 12.4 years (IQR: 11.3-13.2 years). In the CT+GnRHa and CT alone arms, respectively, 9 (10-year cumulative incidence of pregnancy 6.5%, 95% CI 3.5%-12.3%) and 4 (10-year cumulative incidence of pregnancy 3.2%, 95% CI 1.2%-8.3%) patients had a post-treatment pregnancy (HR 2.14, 95% CI 0.66-6.92). No differences in 10-year DFS (72.4% in CT+GnRHa arm vs. 71.2% in CT alone arm: HR 1.16, 95% CI 0.76-1.77) nor in 10-year OS (82.0% in CT+GnRHa arm vs. 85.9% in CT alone arm: HR 1.17, 95% CI 0.67-2.03) were observed. There was no interaction between treatment effect and hormone receptor status. In patients with hormone receptor-positive disease, HR was 1.02 (95% CI 0.63-1.63) for DFS and 1.12 (95% CI 0.59-2.11) for OS. Out of 43 patients tested for BRCA, overall incidence of POI, irrespective of treatment arm, was 20% in mBRCA patients (n = 10) and 12% in patients without mBRCA (n = 33). In mBRCA patients, incidence of POI was 0% and 33% in the CT+GnRHa and CT alone arms, respectively. One post-treatment pregnancy was described in a patient with mBRCA1 in the CT alone arm. Conclusions: The final analysis of the PROMISE-GIM6 trial at a median follow-up of 12.4 years provides reassuring evidence on the safety of GnRHa use during CT as a strategy to preserve ovarian function in premenopausal patients with hormone receptor-positive EBC. Clinical trial information: NCT00311636.

302 Background: In the phase III JAVELIN Renal 101 trial (NCT02684006), A + Ax demonstrated progression-free survival (PFS) and objective response rate (ORR) benefit across IMDC risk groups (favorable, intermediate, and poor) vs S in patients with previously untreated aRCC. Here we report efficacy of A + Ax vs S by number of IMDC risk factors (0, 1, 2, 3, and 4-6) and target tumor sites (1, 2, 3, and ≥4) at baseline from the second interim analysis of overall survival (OS). Methods: Patients were randomized 1:1 to receive A 10 mg/kg intravenously every 2 wk + Ax 5 mg orally twice daily or S 50 mg orally once daily for 4 wk (6-wk cycle). PFS and ORR per independent central review (RECIST 1.1) and OS were assessed. Results: At data cut-off (Jan 2019), median (m) follow-up for OS and PFS was 19.3 vs 19.2 mo and 16.8 vs 15.2 mo for the A + Ax vs S arm, respectively. The table shows OS, PFS, and ORR by number of IMDC risk factors and target tumor sites at baseline. A + Ax generally demonstrated efficacy benefit vs S across subgroups. Conclusions: With extended follow-up, A + Ax generally demonstrated efficacy benefit vs S across the number of IMDC risk factors and tumor sites at baseline in aRCC. OS was still immature; follow-up for the final analysis is ongoing. Clinical trial information: NCT02684006 . [Table: see text]

Long Term Follow Up

A total of 342 previously untreated eligible children were entered into the first Intergroup Ewing's Sarcoma Study (IESS) between May 1973 and November 1978. In group I institutions, patients were randomized between treatment 1 (radiotherapy to primary lesion plus cyclophosphamide, vincristine, dactinomycin, and Adriamycin [doxorubicin; Adria Laboratories, Columbus, OH] [VAC plus ADR]) or treatment 2 (same as treatment 1 without ADR), and group II institutions randomized patients between treatment 2 or treatment 3 (same as treatment 2 plus bilateral pulmonary radiotherapy [VAC plus BPR]). The percentages of patients relapse-free and surviving (RFS) at 5 years for treatments 1, 2, and 3 were 60%, 24%, and 44%, respectively. There was strong statistical evidence of a significant advantage in RFS for treatment 1 (VAC plus ADR) versus 2 (VAC alone) (P less than .001) and 3 (P less than .05) and also of treatment 3 versus 2 (P less than .001). Similar significant results were observed with respect to overall survival. Patients with disease at pelvic sites have significantly poorer survival at 5 years than those with disease at nonpelvic sites (34% v 57%; P less than .001). Among pelvic cases, there was no evidence of differing survival by treatment (P = .81), but among nonpelvic cases, there was strong evidence of differing survival by treatment (P less than .001). The overall percentage of patients developing metastatic disease was 44%; the percentages by treatments 1, 2, and 3 were 30%, 72%, and 42%, respectively. The overall incidence of local recurrence was 15%, and there was no evidence that local recurrence rate differed by treatment. Patient characteristics related to prognosis, both with respect to RFS and overall survival experience, were primary site (nonpelvic patients were most favorable) and patient age (younger patients were more favorable).

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.

Purpose There is no consensus on the optimal systemic treatment of patients with extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue. The IELSG-19 phase III study, to our knowledge, was the first such study to address the question of first-line treatment in a randomized trial. Patients and Methods Eligible patients were initially randomly assigned (1:1 ratio) to receive either chlorambucil monotherapy (6 mg/m2/d orally on weeks 1 to 6, 9 to 10, 13 to 14, 17 to 18, and 21 to 22) or a combination of chlorambucil (same schedule as above) and rituximab (375 mg/m2 intravenously on day 1 of weeks 1, 2, 3, 4, 9, 13, 17, and 21). After the planned enrollment of 252 patients, the protocol was amended to continue with a three-arm design (1:1:6 ratio), with a new arm that included rituximab alone (same schedule as the combination arm) and with a final sample size of 454 patients. The main end point was event-free survival (EFS). Analysis of chlorambucil versus the combination arm was performed and reported separately before any analysis of the third arm. Results At a median follow-up of 7.4 years, addition of rituximab to chlorambucil led to significantly better EFS (hazard ratio, 0.54; 95% CI, 0.38 to 0.77). EFS at 5 years was 51% (95% CI, 42 to 60) with chlorambucil alone, 50% (95% CI, 42 to 59) with rituximab alone, and 68% (95% CI, 60 to 76) with the combination ( P = .0009). Progression-free survival was also significantly better with the combination ( P = .0119). Five-year overall survival was approximately 90% in each arm. All treatments were well tolerated. No unexpected toxicities were recorded. Conclusion Rituximab in combination with chlorambucil demonstrated superior efficacy in mucosa-associated lymphoid tissue lymphoma; however, improvements in EFS and progression-free survival did not translate into longer overall survival.
