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.

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]

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.
