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.

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]

2512 Background: Since 2015, ipilimumab (Ipi) is an approved treatment for stage III melanoma based on a significantly (P=0.0013) prolonged recurrence-free survival (RFS) (Eggermont et al, Lancet Oncology, 2015). At a median follow-up of 5.3 years, RFS (HR=0.76) and distant metastasis-free survival (DMFS) (HR=0.76), assessed by an IRC, and overall survival (OS) (HR=0.72) were prolonged in the Ipi group as compared to the placebo (Pbo) group (Eggermont et al, NEJM, 2016), despite a 53.3% (Ipi) vs 4.6% (Pbo) treatment discontinuation rate due to adverse events. Methods: In this randomized double-blind trial, eligible patients (pts) included those ≥18 yrs of age who underwent complete resection of stage III cutaneous melanoma (excluding lymph node metastasis ≤1 mm or in-transit metastasis). 951 pts were randomized (stratified by stage and region) 1:1 to Ipi 10 mg/kg (n=475) or placebo (Pbo, n=476) q3w for 4 doses, then every 3 mos for up to 3 yrs until completion, disease recurrence, or unacceptable toxicity. Here, we report the comparison between the Ipi and Pbo groups regarding the long-term efficacy outcomes using the local investigator assessments. Results: Overall, 20%/44%/36% of pts had AJCC-7 stage IIIA/IIIB/IIIC, 42% ulcerated primary, and 58% macroscopic lymph node involvement. Median follow-up was 6.9 yrs. The RFS, DMFS and OS benefit observed in the Ipi group was long-lasting (almost 10% difference at 7 years) and consistent across subgroups: no significant predictive factors could be detected. Conclusions: In this phase III trial, Ipi, administered at 10 mg/kg, as adjuvant therapy provided, at a 6.9 yr median follow-up, a sustained improvement in the RFS, DMFS, and OS long-term results in patients with high-risk stage III melanoma. Clinical trial information: NCT00636168. [Table: see text]

LBA9008 Background: Ipilimumab (Ipi), a fully human monoclonal antibody that blocks cytotoxic T-lymphocyte antigen-4 to augment antitumor immune responses, is an approved treatment for advanced melanoma. Here, we report the results of a phase III trial designed to evaluate Ipi as an adjuvant therapy for resected stage III melanoma at high risk of recurrence. Methods: In this randomized, double-blind trial, eligible patients (pts) included those ≥18 yrs of age who underwent complete resection of stage III cutaneous melanoma (excluding lymph node metastasis ≤1 mm or in-transit metastasis). 951 pts were randomized (stratified by stage and region) 1:1 to receive Ipi 10 mg/kg (n=475) or placebo (Pbo, n=476) every 3 wks for 4 doses, then every 3 mos for up to 3 yrs until completion, disease recurrence, or unacceptable toxicity. The primary endpoint was recurrence-free survival (RFS), analyzed on the intent-to-treat population. 512 RFS events (recurrence or death) were needed to provide 90% power to detect an Ipi vs Pbo hazard ratio (HR) of 0.75 (2-sided α=5%). Results: Overall, 20%/44%/36% of pts had stage IIIA/IIIB/IIIC, 42% ulcerated primary, and 58% macroscopic lymph node involvement. At a median follow-up of 2.7 yrs, Ipi significantly improved RFS vs Pbo. RFS benefit was consistent across subgroups (e.g., stage IIIB or IIIC, ulcerated primary). Most common grade 3/4 immune-related adverse events (irAEs) in the Ipi and Pbo arms were gastrointestinal (15.9% vs 0.8%), hepatic (10.6% vs 0.2%), and endocrine (8.5% vs 0%). Most irAEs were managed and resolved using established algorithms. Of 471 pts who started Ipi, 245 (52%) discontinued treatment due to AEs [182 (38.6%) within 12 weeks]; 5 (1.1%) died due to drug-related AEs. Conclusions: In this phase III trial, Ipi as adjuvant therapy provided a clinically and statistically significant improvement in RFS vs Pbo for pts with stage III melanoma at high risk of recurrence. AE profile was generally consistent with that observed in advanced melanoma, although with a higher incidence of endocrinopathies. Clinical trial information: NCT00636168.

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.

5535 Background: To evaluate the safety and efficacy outcomes of concurrent cetuximab plus IMRT and cisplatin in Chinese patients with LA NPC. Methods: Patients with primary stage III-IVb (UICC/AJCC 2002 staging system) and non-keratinizing NPC were enrolled in this prospective, multicentric, phase II study. Cisplatin (80mg/m2,q3week) and cetuximab (400mg/m2 one w before radiation, and then 250mg/m2/w) were given concurrently. The prescription dose of IMRT to GTVnx (primary tumor in nasopharynx) was 66 Gy - 75.9 Gy, GTVnd (positive cervical lymph nodes) was 60 Gy - 70Gy, The response rate was evaluated according to RECIST 1.0 criteria, and adverse events (AEs) were graded according to NCI CTCAE V3.0 criteria. Results: From July 2008 to April 2009, 100 patients were enrolled (74 male), with median age of 43 years. The proportion of stage III, IVa and IVb patients were 71%, 22% and 7% respectively. 99% of enrolled patients completed the planned treatment. AEs were within the expected range and manageable. No toxic death occurred during the treatment. Acneiform skin eruptions, mucositis, in-field dermatitis, xerostomia and neucopenia were the most common seen AEs, with 64% grade 2/3 acneiform eruptions, 26% grade 2/3 in-field dermatitis, 90% ≥ grade 2 mucositis (2 cases of grade 4 mucositis with spontaneous bleeding), 40% ≥ grade 2 xerostomia and 8% grade 2/3 neucopenia. With a median follow-up time of 23.5 months, the 2 year overall survival (OS), disease-free survival (DFS), local recurrence-free survival, regional (cervical lymph node) recurrence free survival and distant metastasis-free survival rates for the ITT population were 91%, 89%, 90%, 90% and 89%, respectively Multivariate analysis showed that N stage was the only prognostic factor for OS (p=0.0392, HR=2.946) and DFS (p=0.0062, HR=4.246) in these patients. Conclusions: Cetuximab combined with IMRT plus concurrent cisplatin in patients with LA NPC shows satisfactory 2-year locoregional control rate and 2-year overall survival. The combination seems to be well tolerated with a manageable side-effect profile.
