10012 Background: Treatment of patients with BRAF V600–mutant melanoma includes BRAF/MEK-inhibitor combinations based on demonstrated benefits on progression-free survival (PFS) and overall survival (OS). To better understand the proportion of patients who derive long-lived benefit and their characteristics, we performed an updated analysis of OS and other endpoints from the COLUMBUS trial. Methods: In Part 1 of COLUMBUS, 577 patients with advanced/metastatic BRAF V600‒mutant melanoma, untreated or progressed after first-line immunotherapy, were randomized 1:1:1 to ENCO 450 mg QD + BINI 45 mg BID (COMBO450) vs VEM 960 mg BID (VEM) or ENCO 300 mg QD (ENCO300). An updated analysis including PFS, OS, objective response rate (ORR), and safety was conducted after an additional 24 months’ follow-up from the initial analysis. The study is ongoing. Results: At data cutoff (November 2019, as-is data), events had occurred in 65%, 59%, and 75% of patients in the COMBO450, ENCO300, and VEM treatment arms, respectively. Across arms, median follow-up for OS was 60.6 months (mo), with median OS of 33.6 mo (95% CI, 24.4–39.2) for COMBO450, 23.5 mo (95% CI, 19.6–33.6) for ENCO300, and 16.9 mo (95% CI, 14.0–24.5) for VEM. Compared to VEM, COMBO450 decreased the risk of death by 38% (HR, 0.62 [95% CI, 0.49–0.79]). Updated median PFS was COMBO450, 14.9 mo (95% CI, 11.0–20.2), ENCO300, 9.6 mo (95% CI, 7.4–14.8), and VEM, 7.3 mo (95% CI, 5.6–7.9). PFS was longer for COMBO450 vs VEM (HR, 0.52 [95% CI, 0.40–0.67]). A landmark analysis showed a higher rate of OS for COMBO450 at each year analyzed, with OS rates at 4 years of 39%, 37%, and 26% COMBO450, ENCO300, and VEM, respectively. Updated safety analysis confirmed the beneficial long-term tolerability of COMBO450. Conclusions: In the COLUMBUS trial, results for updated PFS and OS with COMBO450 continue to demonstrate long-term benefits in patients with BRAF V600‒mutated melanoma. Clinical trial information: NCT01909453.

9512 Background: BRAF/MEK-inhibitor combinations have a central role in the treatment of BRAF V600–mutant melanoma based on demonstrated benefits on progression-free survival (PFS) and overall survival (OS). Because of these meaningful improvements in outcome, mature landmark analyses of PFS and OS, as well as analyses of some prognostic subgroups, require long-term follow-up. Here we report an updated analysis of OS and other endpoints from the COLUMBUS trial. Methods: In Part 1 of COLUMBUS, 577 patients with advanced/metastatic BRAF V600‒mutant melanoma, untreated or progressed after first-line immunotherapy, were randomized 1:1:1 to ENCO 450 mg QD + BINI 45 mg BID (COMBO450) vs VEM 960 mg BID (VEM) or ENCO 300 mg QD (ENCO300). An updated analysis including PFS, OS, objective response rate (ORR), safety and tolerability, and analyses of results by prognostic subgroups including elevated lactate dehydrogenase (LDH) and degree of organ involvement was conducted after an additional 12 months’ follow-up. Results: At data cutoff, there were 116, 113, and 138 deaths in the COMBO450, ENCO300, and VEM treatment arms, respectively. Across arms, median follow-up for OS was 48.6 months (mo), with median OS of 33.6 mo (95% CI, 24.4–39.2) for COMBO450, 23.5 mo (95% CI, 19.6–33.6) for ENCO300, and 16.9 mo (95% CI, 14.0–24.5) for VEM. Compared to VEM, COMBO450 decreased the risk of death by 39% (HR, 0.61 [95% CI, 0.48–0.79). Updated median PFS was COMBO450, 14.9 mo (95% CI, 11.0–20.2), ENCO300, 9.6 mo (95% CI, 7.4–14.8), and VEM, 7.3 mo (95% CI, 5.6–8.2). PFS was longer for COMBO450 vs VEM (HR, 0.52 [95% CI, 0.40–0.67). Landmark OS and PFS results, as well as subgroup analyses and updated safety and tolerability, will be presented. Conclusions: Updated PFS and OS results for COMBO 450 from the COLUMBUS trial continue to represent new benchmarks for combined BRAF/MEK-inhibitor combinations for treatment of BRAF V600‒mutated melanoma.

Objective: This study aimed to explore the immediate postoperative and long-term outcomes of central neurocytoma (CN) based on 15 years of experience in our institution.Methods: This single-institution study collected data of 43 patients with CN who underwent surgery between 2005 and 2020. We reviewed data of clinical, immediate postoperative outcome, and long-term outcome of patients. More specifically, we divided complications into neurological and regional complications groups.Results: Among the 43 patients with CN who underwent surgery, the transcortical (72.1%) or transcallosal (25.6%) approach was used. There were 18 patients (41.9%) who complained about postoperative neurological complications, including motor weakness (25.6%), memory deficit (18.6%), aphasia (7.0%), and seizure (4.7%). In addition, 18 patients suffered postoperative regional complications such as hydrocephalus (2.3%), hematoma (34.9%), infection (4.7%), and subcutaneous hydrops (2.3%). Only one-quarter of patients had suffered permanent surgical complications. The majority of patients recovered from the deficit and could turn back to normal life. There were no significant differences in the clinical outcomes between transcortical and transcallosal approaches. At a median follow-up of 61.8 months, the 5-year overall survival and progression-free survival were 87.0 and 74.0%, respectively. A multivariate Cox model analysis showed that the extent of resection was not related to progression-free survival. However, the extent of resection was significantly associated with overall survival, and gross total resection decreased the risk of death.Conclusions: Patients with CN show favorable outcomes after surgery. The transcortical and transcallosal approaches have similar postoperative complication rates and long-term follow-up outcomes. In terms of long-term prognosis, maximal safety resection should be the first choice of CN.

2008b Background: Anaplastic oligodendrogliomas, pure (AO) and mixed (AOA), are chemosensitive tumors, especially if co-deleted for chromosomes 1p and 19q, but whether addition of CT to RT prolongs overall survival (OS), is unknown. Methods: In the RTOG 9402 Phase III trial, patients (pts) with AO/AOA were randomly assigned to PCV [procarbazine, CCNU (lomustine) and vincristine] followed by immediate RT vs. immediate RT alone. Early analysis showed no OS benefit for the PCV+RT group but combined therapy was associated with a longer progression-free survival (PFS). It also showed that the finding of 1p/19q co-deletion was associated with a longer OS independent of treatment. The current analysis has a median follow up of 11.3 years (yrs). Results: Two hundred ninety-one patients were randomized, 148 to PCV+RT and 143 to RT. PCV+RT was associated with longer PFS [2.5 vs. 1.7 yrs, hazard ratio (HR) 0.68, 95% confidence interval (CI) (0.53, 0.88), P = 0.003] and the 1p/19q co-deletion with a longer Median Survival Time (MST) [8.7 vs. 2.7 yrs, HR 0.41, 95% CI (0.30, 0.55), P < 0.001]. For the entire cohort, there was no difference in MST by treatment [4.6 yrs for PCV+RT vs. 4.7 yrs for RT, HR 0.79, 95% CI (0.60, 1.04), P = 0.1]. However, patients with 1p/19q co-deleted tumors lived much longer after PCV+RT (n = 59) than after RT (n = 67) [14.7 vs. 7.3 yrs, HR 0.59, 95% CI (0.37, 0.95), P = 0.03]. There was no difference in MST by treatment in pts without the 1p/19q co-deletion [n=137; 2.6 vs. 2.7 yrs, HR 0.85, 95% CI (0.58, 1.23), P = 0.39]. Re-operation rates upon progression were similar between treatment arms in co-deleted pts (43%, PCV+RT vs. 54%, RT) but salvage CT rates were higher in the RT arm [57% vs. 81% (P = 0.04)]. Conclusions: PCV followed by immediate RT was a highly effective therapy for patients with 1p/19q co-deleted AO/AOA. In this setting, 1p/19q co-deletion was both prognostic and predictive, and the early PFS benefit in co-deleted cases was a harbinger of their longer OS.

Abstract Purpose: Alemtuzumab (MabCampath) is a humanized monoclonal antibody that targets the CD52 antigen, which is highly expressed on most human B and T lymphocytes. Alemtuzumab has shown considerable activity in both relapsed/refractory CLL and in the frontline treatment setting. In a recent study, treatment with single-agent alemtuzumab induced MRD-negative remissions in 20% of patients with relapsed/refractory CLL (Moreton et al JCO 2005;23:2971–2979). Other studies suggest that MRD negativity can also be attained when alemtuzumab is administered as consolidation for patients with CLL who achieve incomplete initial responses to chemotherapy. Here, we report our long-term experience within a randomized phase III trial that investigates the role of alemtuzumab for consolidation therapy in patients with previously untreated CLL. Methods: Pts in complete or partial remission after induction chemotherapy, with either fludarabine (F) or fludarabine plus cyclophosphamide (FC), were randomized to receive either alemtuzumab 30 mg, 3 times a week for ≤12 wks or no further treatment. Of 21 eligible pts, who had responded to induction with F or FC (1 CR, 1 nPR, 9 PRs), 11 pts (median age: 60 years) randomized to receive alemtuzumab consolidation and 10 to the observation arm. Pts in the alemtuzumab arm received standard premedication and infection prophylaxis with famciclovir and trimethoprim/sulfamethoxazole. Results: After a median follow-up of 48 months, calculated from time of randomization within this consolidation trial, progression-free survival (PFS) was significantly improved for pts who received alemtuzumab consolidation compared to those who received no further treatment (median PFS not reached versus 20.6 months, P = 0.004). PFS from the beginning of induction therapy with F or FC is also significantly greater for patients in the alemtuzumab consolidation arm versus the observation arm. So far, 3 of 11 pts presented with disease progression after alemtuzumab consolidation compared with 8/10 progressing pts in the observation arm. Differences in PFS between both arms were not associated with disease stage before first line treatment, type of first line chemotherapy (F vs. FC) or response status before initiation of consolidation therapy (CR vs. nPR vs. PR). Correlations between achievement of MRD negative responses and PFS is still under investigation and is planned for presentation. With the exception of 2 patients (1 pt in each arm) all patients remain alive. The study was stopped prematurely due to severe infections (7 CTC III infections, which included 4 CMV reactivations, 1 CTC IV infection) in 7/11 patients being treated with alemtuzumab. However, these infections were successfully treated, not associated with the cumulative dose of alemtuzumab, and no late complications of consolidation therapy have been observed. Conclusions: Although based on few pts due to incomplete accrual, long-term PFS was significantly prolonged in patients with CLL receiving alemtuzumab consolidation after first line chemotherapy with F or FC. An ongoing phase I/II trial of the GCLLSG (CLL2i) is currently evaluating the optimal dose and schedule of alemtuzumab in CLL pts after fludarabine-based chemotherapy.

PURPOSE In the phase III CheckMate 067 trial, durable clinical benefit was demonstrated previously with nivolumab plus ipilimumab and nivolumab alone versus ipilimumab. Here, we report 6.5-year efficacy and safety outcomes. PATIENTS AND METHODS Patients with previously untreated unresectable stage III or stage IV melanoma were randomly assigned 1:1:1 to receive nivolumab 1 mg/kg plus ipilimumab 3 mg/kg once every 3 weeks (four doses) followed by nivolumab 3 mg/kg once every 2 weeks (n = 314), nivolumab 3 mg/kg once every 2 weeks (n = 316), or ipilimumab 3 mg/kg once every 3 weeks (four doses; n = 315). Coprimary end points were progression-free survival and overall survival (OS) with nivolumab plus ipilimumab or nivolumab versus ipilimumab. Secondary end points included objective response rate, descriptive efficacy assessments of nivolumab plus ipilimumab versus nivolumab alone, and safety. Melanoma-specific survival (MSS; descriptive analysis), which excludes deaths unrelated to melanoma, was also evaluated. RESULTS Median OS (minimum follow-up, 6.5 years) was 72.1, 36.9, and 19.9 months in the combination, nivolumab, and ipilimumab groups, respectively. Median MSS was not reached, 58.7, and 21.9 months, respectively; 6.5-year OS rates were 57%, 43%, and 25% in patients with BRAF-mutant tumors and 46%, 42%, and 22% in those with BRAF–wild-type tumors, respectively. In patients who discontinued treatment, the median treatment-free interval was 27.6, 2.3, and 1.9 months, respectively. Since the 5-year analysis, no new safety signals were observed. CONCLUSION These 6.5-year CheckMate 067 results, which include the longest median OS in a phase III melanoma trial reported to date and the first report of MSS, showed durable, improved clinical outcomes with nivolumab plus ipilimumab or nivolumab versus ipilimumab in patients with advanced melanoma and, in descriptive analyses, with the combination over nivolumab monotherapy.

Phase Iii Trial

PurposePatients with advanced pancreatic cancer have a poor prognosis and there have been no improvements in survival since the introduction of gemcitabine in 1996. Pancreatic tumors often overexpress human epidermal growth factor receptor type 1 (HER1/EGFR) and this is associated with a worse prognosis. We studied the effects of adding the HER1/EGFR-targeted agent erlotinib to gemcitabine in patients with unresectable, locally advanced, or metastatic pancreatic cancer.Patients and MethodsPatients were randomly assigned 1:1 to receive standard gemcitabine plus erlotinib (100 or 150 mg/d orally) or gemcitabine plus placebo in a double-blind, international phase III trial. The primary end point was overall survival.ResultsA total of 569 patients were randomly assigned. Overall survival based on an intent-to-treat analysis was significantly prolonged on the erlotinib/gemcitabine arm with a hazard ratio (HR) of 0.82 (95% CI, 0.69 to 0.99; P = .038, adjusted for stratification factors; median 6.24 months v 5.91 months). One-year survival was also greater with erlotinib plus gemcitabine (23% v 17%; P = .023). Progression-free survival was significantly longer with erlotinib plus gemcitabine with an estimated HR of 0.77 (95% CI, 0.64 to 0.92; P = .004). Objective response rates were not significantly different between the arms, although more patients on erlotinib had disease stabilization. There was a higher incidence of some adverse events with erlotinib plus gemcitabine, but most were grade 1 or 2.ConclusionTo our knowledge, this randomized phase III trial is the first to demonstrate statistically significantly improved survival in advanced pancreatic cancer by adding any agent to gemcitabine. The recommended dose of erlotinib with gemcitabine for this indication is 100 mg/d.

PurposeTo assess potential differences in progression-free or overall survival when imatinib mesylate is administered to patients with incurable gastrointestinal stromal tumors (GIST) at a standard dose (400 mg daily) versus a high dose (400 mg twice daily).Patients and MethodsPatients with metastatic or surgically unresectable GIST were eligible for this phase III open-label clinical trial. At registration, patients were randomly assigned to either standard or high-dose imatinib, with close interval follow-up. If objective progression occurred by Response Evaluation Criteria in Solid Tumors, patients on the standard-dose arm could reregister to the trial and receive the high-dose imatinib regimen.ResultsSeven hundred forty-six patients with advanced GIST from 148 centers across the United States and Canada were enrolled onto this trial in 9 months. With a median follow-up of 4.5 years, median progression-free survival was 18 months for patients on the standard-dose arm, and 20 months for those receiving high-dose imatinib. Median overall survival was 55 and 51 months, respectively. There were no statistically significant differences in objective response rates, progression-free survival, or overall survival. After progression on standard-dose imatinib, 33% of patients who crossed over to the high-dose imatinib regimen achieved either an objective response or stable disease. There were more grade 3, 4, and 5 toxicities noted on the high-dose imatinib arm.ConclusionThis trial confirms the effectiveness of imatinib as primary systemic therapy for patients with incurable GIST but did not show any advantage to higher dose treatment. It appears reasonable to initiate therapy with 400 mg daily and to consider dose escalation on progression of disease.

455 Background: The POUT trial (CRUK/11/027; NCT01993979) previously reported (with median follow-up 30.3 months) that adjuvant chemotherapy improves disease free survival (DFS) for patients (pts) with histologically confirmed pT2-T4 N0-3 M0 UTUC. Here we present results of a pre-planned analysis updating the primary endpoint and reporting key secondary endpoints including overall survival. Methods: 261 pts with UTUC were enrolled following nephro-ureterectomy and randomised (1:1) to 4 cycles of gemcitabine-cisplatin (gemcitabine-carboplatin if GFR 30-49ml/min) or surveillance with subsequent chemotherapy if required. Pts had 6 monthly imaging and cystoscopy for 2 years, then annually to 5 years. Toxicity was assessed by CTCAE v4. Primary endpoint was DFS. Secondary endpoints included metastasis free survival (MFS), overall survival (OS), toxicity and patient reported quality of life (QoL). The trial closed to recruitment early on advice of the independent data monitoring committee due to evidence of efficacy. Time-to-event endpoints are analysed (intention-to-treat) by Cox proportional hazard models. Unadjusted and adjusted (by nodal status, planned chemotherapy type, microscopic margin status, pathological stage) hazard ratios (HR, < 1 favouring chemotherapy) are reported. Results: From May 2012 to Nov 2017, 261 pts were recruited (129 surveillance; 132 chemotherapy) at 56 UK centres. One participant withdrew consent for data usage and was excluded from analyses. Pts had median age 69 years (range 37-88), 28% pT2, 66% pT3; 91% pN0. To 09/09/2020, median follow up was 48.1 months (IQR: 36.0-60.1). The unadjusted/adjusted HR for DFS was 0.48 (95% CI: 0.33-0.71; p = 0.0003) / 0.50 (95%CI: 0.34-0.75; p = 0.001), and for MFS was 0.52 (95% CI: 0.35-0.77; p = 0.001) / 0.54 (95% CI: 0.36-0.81; p = 0.002). 93/260 (35.8%) pts have died (52/129 [40.3%] surveillance and 41/131 [31.3%] chemotherapy). Chemotherapy conferred a non-statistically significant 28% reduction in relative risk of death (HR = 0.72, 95% CI: 0.47-1.08; p = 0.11; adjusted HR = 0.79, 95% CI: 0.52-1.19; p = 0.26). 3 year OS was surveillance: 67% (95% CI: 58-74%; chemotherapy: 79% (71%-85%). There was no evidence of long-term toxicity associated with chemotherapy (Wilcoxon rank-sum test p-value for worst grade post-6 months = 0.32). Most common grade 2+ adverse events were hypertension (25/240 [10.4%]), lethargy (25/240 [10.4%]) and hearing loss (13/240 [5.4%]). There was no evidence of statistically or clinically relevant differences in QoL. 12 months after treatment (EORTC Q30 global health status mean difference 4.1 and 4.8 at 12 and 24 months respectively in favour of chemotherapy). Conclusions: With additional follow-up, the previously reported DFS benefit for chemotherapy was maintained with no detrimental long-term toxicity. No statistically significant improvement in OS was observed. Clinical trial information: NCT01993979.

Purpose Progesterone receptors are expressed in approximately 70% of meningiomas. Mifepristone is an oral antiprogestational agent reported to have modest activity in a phase II study. This multicenter, prospective, randomized, placebo-controlled phase III trial conducted by SWOG was planned to define the role of mifepristone in the treatment of unresectable meningioma. Patients and Methods Eligible patients were randomly assigned to receive either mifepristone or placebo for 2 years unless disease progressed. Patients who were stable or responding to protocol therapy after 2 years had the option to continue with the same blinded therapy. Serial follow-up allowed assessment of efficacy and toxicity. Time to treatment failure and overall survival were ascertained for all randomly assigned patients. On progression, patients receiving placebo could cross over and receive active drug. Results Among 164 eligible patients, 80 were randomly assigned to mifepristone and 84 to placebo. Twenty-four patients (30%) were able to complete 2 years of mifepristone without disease progression, adverse effects, or other reasons for discontinuation. Twenty-eight patients (33%) in the placebo arm completed the 2-year study. There was no statistical difference between the arms in terms of failure-free or overall survival. Conclusion Long-term administration of mifepristone was well tolerated but had no impact on patients with unresectable meningioma.
