BackgroundSeveral therapeutic options are now available in the adjuvant melanoma setting, mandating an understanding of their benefit‒risk profiles in order to make informed treatment decisions. Herein we characterize adjuvant nivolumab select (immune-related) treatment-related adverse events (TRAEs) and evaluate possible associations between safety and recurrence-free survival (RFS) in the phase III CheckMate 238 trial.MethodsPatients with resected stage IIIB–C or IV melanoma received nivolumab 3 mg/kg every 2 weeks (n=452) or ipilimumab 10 mg/kg every 3 weeks for four doses and then every 12 weeks (n=453) for up to 1 year or until disease recurrence, unacceptable toxicity, or consent withdrawal. First-occurrence and all-occurrence select TRAEs were analyzed within discrete time intervals: from 0 to 3 months of treatment, from >3–12 months of treatment, and from the last dose (regardless of early or per-protocol treatment discontinuation) to 100 days after the last dose. Possible associations between select TRAEs and RFS were investigated post randomization in 3-month landmark analyses and in Cox model analyses (including a time-varying covariate of select TRAE), within and between treatment groups.ResultsFrom the first nivolumab dose to 100 days after the last dose, first-occurrence select TRAEs were reported in 67.7% (306/452) of patients. First-occurrence select TRAEs were reported most frequently from 0 to 3 months (48.0%), during which the most common were pruritus (15.5%) and diarrhea (15.3%). Most select TRAEs resolved within 6 months. There was no clear association between the occurrence (or not) of select TRAEs and RFS by landmark analysis or by Cox model analysis within treatment arms or comparing nivolumab to the ipilimumab comparator arm.ConclusionResults of this safety analysis of nivolumab in adjuvant melanoma were consistent with its established safety profile. In the discrete time intervals evaluated, most first-occurrence TRAEs occurred early during treatment and resolved. No association between RFS and select TRAEs was evident.Trial registration numberNCT02388906.

IntroductionHyperthermic intraperitoneal chemotherapy (HIPEC) improved investigator-assessed recurrence-free survival and overall survival in patients with stage III ovarian cancer in the phase III OVHIPEC-1 trial. We analyzed whether an open-label design affected the results of the trial by central blinded assessment of recurrence-free survival, and tested whether HIPEC specifically targets the peritoneal surface by analyzing the site of disease recurrence.MethodsOVHIPEC-1 was an open-label, multicenter, phase III trial that randomized 245 patients after three cycles of neoadjuvant chemotherapy to interval cytoreduction with or without HIPEC using cisplatin (100 mg/m2). Patients received three additional cycles of chemotherapy after surgery. Computed tomography (CT) scans and serum cancer antigen 125 (CA125) measurements were performed during chemotherapy, and during follow-up. Two expert radiologists reviewed all available CT scans. They were blinded for treatment allocation and clinical outcome. Central revision included Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 measurements and peritoneal cancer index scorings at baseline, during treatment, and during follow-up. Time to centrally-revised recurrence was compared between study arms using Cox proportional hazard models. Subdistribution models compared time to peritoneal recurrence between arms, accounting for competing risks.ResultsCT scans for central revision were available for 231 patients (94%) during neoadjuvant treatment and 212 patients (87%) during follow-up. Centrally-assessed median recurrence-free survival was 9.9 months in the surgery group and 13.2 months in the surgery+HIPEC group (HR for disease recurrence or death 0.72, 95% CI 0.55 to 0.94; p=0.015). The improved recurrence-free survival and overall survival associated with HIPEC were irrespective of response to neoadjuvant chemotherapy and baseline peritoneal cancer index. Cumulative incidence of peritoneal recurrence was lower after surgery+HIPEC, but there was no difference in extraperitoneal recurrences.ConclusionCentrally-assessed recurrence-free survival analysis confirms the benefit of adding HIPEC to interval cytoreductive surgery in patients with stage III ovarian cancer, with fewer peritoneal recurrences. These results rule out radiological bias caused by the open-label nature of the study.

TPS145 Background: Adjuvant pembrolizumab showed significantly longer recurrence-free survival compared with placebo in resected stage III melanoma in the KEYNOTE-054 study [1]. KEYNOTE-716 is a randomized, placebo-controlled, multicenter phase 3 study of adjuvant pembrolizumab in patients with surgically resected high-risk stage II melanoma. Methods: Patients must be ≥12 years of age and have newly diagnosed, completely resected stage IIB/IIC cutaneous melanoma, defined by the AJCC Cancer Staging Manual, 8th edition [2] (wide excision and negative sentinel lymph node biopsy, with no evidence of distant metastasis). Patients cannot have mucosal or uveal melanoma or have received prior treatment for melanoma, including radiation, beyond resection of primary disease within 12 weeks of the start of study therapy. The study has a 2-part design. In the double-blind phase (part 1), patients will be randomly assigned 1:1 to receive pembrolizumab 200 mg for patients ≥18 years or 2 mg/kg for patients 12-17 years (maximum dose, 200 mg) or placebo every 3 weeks for 17 cycles. Stratification: 1 stratum for pediatric patients (12-17 years); 3 strata for adult patients per T stage (T3b/T4a/T4b). Study treatment will begin within 12 weeks of complete resection. Tumor imaging will be performed every 24 weeks while treatment is ongoing, at the end of treatment, every 6 months for the first 3 years off treatment, and then yearly for up to 2 years or until recurrence (up to 5 years of total imaging). Adverse events will be graded per NCI Common Terminology Criteria for Adverse Events, version 4.0. In the unblinded phase (part 2), patients with confirmed recurrence may be rechallenged (patients received pembrolizumab in part 1) or crossed over to pembrolizumab (patients received placebo in part 1). Resected local or distant recurrence or unresectable disease will be treated for an additional 17 or 35 cycles, respectively. Tumor imaging in part 2 will occur every 12 weeks while treatment is ongoing. The primary end point is recurrence-free survival; secondary end points are distant metastasis-free survival, overall survival, and safety. Approximately 954 patients will be enrolled. Clinical trial information: NCT03553836.

AbstractWhether extensive intraoperative peritoneal lavage (EIPL) after gastrectomy is beneficial to patients with locally advanced gastric cancer (AGC) is not clear. This phase 3, multicenter, parallel-group, prospective randomized study (NCT02745509) recruits patients between April 2016 and November 2017. Eligible patients who had been histologically proven AGC with T3/4NxM0 stage are randomly assigned (1:1) to either surgery alone or surgery plus EIPL. The results of the two groups are analyzed in the intent-to-treat population. A total of 662 patients with AGC (329 patients in the surgery alone group, and 333 in the surgery plus EIPL group) are included in the study. The primary endpoint is 3-year overall survival (OS). The secondary endpoints include 3-year disease free survival (DFS), 3-year peritoneal recurrence-free survival (reported in this manuscript) and 30-day postoperative complication and mortality (previously reported). The trial meets pre-specified endpoints. Estimated 3-year OS rates are 68.5% in the surgery alone group and 70.6% in the surgery plus EIPL group (log-rank p = 0.77). 3-year DFS rates are 61.2% in the surgery alone group and 66.0% in the surgery plus EIPL group (log-rank p = 0.24). The pattern of disease recurrence is similar in the two groups. In conclusion, EIPL does not improve the 3-year survival rate in AGC patients.

The Impact

PURPOSE We conducted the phase III double-blind European Organisation for Research and Treatment of Cancer (EORTC) 1325/KEYNOTE-054 trial to evaluate pembrolizumab versus placebo in patients with resected high-risk stage III melanoma. On the basis of 351 recurrence-free survival (RFS) events at a 1.25-year median follow-up, pembrolizumab prolonged RFS (hazard ratio [HR], 0.57; P < .0001) compared with placebo. This led to the approval of pembrolizumab adjuvant treatment by the European Medicines Agency and US Food and Drug Administration. Here, we report an updated RFS analysis at the 3.05-year median follow-up. PATIENTS AND METHODS A total of 1,019 patients with complete lymph node dissection of American Joint Committee on Cancer Staging Manual (seventh edition; AJCC-7), stage IIIA (at least one lymph node metastasis > 1 mm), IIIB, or IIIC (without in-transit metastasis) cutaneous melanoma were randomly assigned to receive pembrolizumab at a flat dose of 200 mg (n = 514) or placebo (n = 505) every 3 weeks for 1 year or until disease recurrence or unacceptable toxicity. The two coprimary end points were RFS in the overall population and in those with programmed death-ligand 1 (PD-L1)–positive tumors. RESULTS Pembrolizumab (190 RFS events) compared with placebo (283 RFS events) resulted in prolonged RFS in the overall population (3-year RFS rate, 63.7% v 44.1% for pembrolizumab v placebo, respectively; HR, 0.56; 95% CI, 0.47 to 0.68) and in the PD-L1–positive tumor subgroup (HR, 0.57; 99% CI, 0.43 to 0.74). The impact of pembrolizumab on RFS was similar in subgroups, in particular according to AJCC-7 and AJCC-8 staging, and BRAF mutation status (HR, 0.51 [99% CI, 0.36 to 0.73] v 0.66 [99% CI, 0.46 to 0.95] for V600E/K v wild type). CONCLUSION In resected high-risk stage III melanoma, pembrolizumab adjuvant therapy provided a sustained and clinically meaningful improvement in RFS at 3-year median follow-up. This improvement was consistent across subgroups.

Clinical Trial Information

e19022 Background: Progression-free survival (PFS) is a key trial end point for clinical practice, as it relates to a change of treatment line. Grade 4 progression-free survival (G4PFS; defined as time from treatment start to the earlier of progressive disease [PD], onset of a G4 adverse event [AE], or death from any cause) is a composite end point incorporating a measure of tolerability to PFS. This post hoc analysis evaluates G4PFS and the effect of G4 AEs on PFS and overall survival (OS) in patients (pts) enrolled in PointBreak (PB) and AVAiL. Methods: Pts in PB were randomized to bevacizumab (BEV) 15 mg/kg q3w with carboplatin and paclitaxel (CP) or pemetrexed (CPem) for ≤4 cycles. Eligible pts received either BEV or BEV + Pem q3w until PD or unacceptable toxicity. Pts in AVAiL received cisplatin and gemcitabine for ≤6 cycles and either placebo or BEV (7.5 or 15 mg/kg) q3w until PD. AEs were graded via NCI-CTCAE v3.0. Kaplan-Meier and Cox model methods were used to estimate medians and hazard ratios (HRs) for PFS, G4PFS, and OS. PFS and OS were also compared in each arm for pts with occurrence of a G4 AE before week 12 of treatment vs those without. Results: Of those receiving BEV, ~30% of AVAiL pts and 38% of PB pts had a G4 AE. Uncomplicated neutropenia was the most common G4 AE in the CP + BEV arm of PB (26%) and in the BEV arms of AVAiL (11%). PFS, G4PFS, and outcomes by G4 AE occurrence are shown (Table). Conclusions: In both the PB and AVAiL trials, median G4PFS was numerically shorter than median PFS. G4 AE occurrence, however, did not affect subsequent PFS or OS in either trial. Clinical trial information: NCT00762034 and NCT00806923. [Table: see text]

3515 Background: The no-touch isolation technique (NTIT) aims to reduce cancer cells flowing from the primary tumor site to the liver and other organs by first ligation of blood vessels that feed the primary tumor. The efficacy of NTIT has not been proved in previous studies. To acquire the answer of an unsolved problem more than 60 years, we conducted a phase III trial to confirm the superiority of NTIT in patients with cT3/T4 colon cancer. This is the primary analysis of the disease-free survival (DFS) as the primary endpoint. Methods: Eligibility criteria included histologically proven colon cancer; tumor located in the cecum, ascending, transverse, descending, sigmoid or rectosigmoid colon; clinical T3 or T4, N0-2, M0; patients age 20-80 years. Patients were randomized preoperatively to either conventional technique (CoT) arm or NTIT arm. Operation was performed in open surgery. Patients with pathological stage III received adjuvant chemotherapy with capecitabine. The primary endpoint was DFS. Planned sample size was 850 to detect a hazard ratio (HR) of 0.732 in DFS with one-sided alpha of 5% and power of 80%. Results: A total of 853 patients were randomized (CoT: 427, NTIT: 426) between January 2011 and November 2015. The 3-year DFS were 77.3% and 76.2% in the CoT arm and NTIT arm,respectively. The HR was 1.029(95% CI 0.800-1.324); thus the superiority of NTIT was not confirmed (p = 0.59). The 3-year overall survival (OS), 3-year recurrence-free survival (RFS) and 3-year liver-recurrence-free survival (LRFS) are shown in the Table. Conclusions: The superiority of NTIT to CoT was not confirmed. NTIT does not improve the DFS or OS, RFS, LRFS in the patents with stage II and III colon cancer.

e15765 Background: Although adjuvant chemotherapy with gemcitabine has for years been the standard of care for resected pancreatic cancer, the role of adjuvant radiation is still debatable. We aimed to investigate the efficacy of gemcitabine combined with stereotactic body radiation therapy (SBRT) as adjuvant therapy for resected stage II pancreatic cancer. Methods: This single center randomized controlled trial was designed to enroll 512 patients with stage II pancreatic cancer that underwent curative-intended radical resection from a large-volume tertiary pancreatic center in China. Patients were randomly assigned to gemcitabine-alone adjuvant chemotherapy or adjuvant SBRT (25 Gray in 5 fractions) followed by gemcitabine chemotherapy. The primary endpoint was recurrence-free survival (RFS). Secondary endpoints included locoregional recurrence-free survival (LRFS), overall survival (OS), and incidence of adverse events. Interim analysis was planned at the time of 2.5-years’ enrollment. Results: 40 patients were randomly assigned to treatment between Sep 1, 2015, and Mar 31, 2018 (21 to the gemcitabine group and 19 to the gemcitabine plus SBRT group). Of these, one was excluded because of ineligibility and one did not receive any treatment. The median RFS was 12.4 (9.3-15.6) months in the gemcitabine group and 14.7 (9.2-20.1) months in the gemcitabine plus SBRT group ( P= 0.753), with median LRFS of 18.2 (14.6-21.7) months in the gemcitabine group and 13.1 (9.1-16.8) months in the gemcitabine plus SBRT group ( P= 0.333). The median OS was 21.7 (19.5-24.0) months in the gemcitabine group and 16.9 (12.8-20.9) in the gemcitabine plus SBRT group ( P= 0.066). Grade 3 or 4 neutropenia, thrombocytopenia, nausea or vomiting, and liver dysfunction were all comparable between the two groups. Evaluation of data from the first 40 enrolled patients indicated that the addition of adjuvant SBRT was not associated with either better local disease control or recurrence free survival. And because of failure to achieve the accrual target, the trial was terminated prematurely. Conclusions: Adjuvant SBRT neither provided a survival benefit nor improved local disease control in resected stage II pancreatic cancer. Clinical trial information: NCT02461836.

10000 Background: We conducted the phase 3 double-blind EORTC 1325/KEYNOTE-054 trial to evaluate pembrolizumab vs placebo in patients (pts) with resected high-risk stage III melanoma. Based on 351 recurrence-free survival (RFS) events and at a median follow-up of 1.25 years (yrs), pembrolizumab improved RFS (hazard ratio (HR) 0.57, P<0.0001) as compared to placebo (Eggermont, NEJM 2018). This led to the approval of pembrolizumab adjuvant treatment by EMA and FDA. Methods: Eligible pts included those ≥18 yrs of age with complete resection of cutaneous melanoma metastatic to lymph node(s), classified as AJCC-7 stage IIIA (at least one lymph node metastasis >1 mm), IIIB or IIIC (without in-transit metastasis). A total of 1019 pts were randomized (stratification by stage and region) to pembrolizumab at a flat dose of 200 mg (N=514) or placebo (N=505) every 3 weeks for a total of 18 doses (~1 year) or until disease recurrence or unacceptable toxicity. The 2 co-primary endpoints were RFS in the intention-to-treat overall population and in pts with PD-L1-positive tumors. Here, we report an updated RFS analysis based on a longer follow-up. Results: Overall, 15%/46%/39% of pts had stage IIIA/IIIB/IIIC. At 3.05-yr median follow-up, pembrolizumab (190 RFS events) compared with placebo (283 RFS events) prolonged RFS, in the overall population and in the PD-L1 positive tumor subgroup (see Table). RFS was consistently prolonged across subgroups, in particular according to AJCC-7 staging, BRAF-V600 E/K mutation status. Conclusions: Pembrolizumab, administered at 200 mg every 3 weeks for up to 1 year as adjuvant therapy, provided, at a 3-yr median follow-up, a sustained improvement in RFS, which was clinically meaningful, in resected high-risk stage III melanoma. This improvement was consistent across subgroups. In the overall population, the 3-yr cumulative incidence of distant metastasis being the first recurrence was 22.3% (pembrolizumab group) vs 37.3% (placebo group) (HR 0.55, 95% CI 0.44-0.69). Clinical trial information: NCT02362594. [Table: see text]
