9586 Background: The combination of IPI+NIVO induces high response rates and improved overall survival in late stage melanoma. T cell checkpoint inhibition is of greatest value at the moment of TCR triggering and therefore dependent on the amount of antigen present, indicating that adjuvant immunotherapy may work most efficiently, when initiated prior to surgery. Methods: Two-arm Phase 1b feasibility trial of 20 high risk AJCC stage IIIB and IIIC melanoma patients with palpable nodal disease receiving the combination of IPI 3mg/kg and NIVO 1mg/kg, either adjuvant four courses after surgery, or split two courses neo-adjuvant and two courses adjuvant. Results: In this update all 20 patients are evaluable. Neo-adjuvant application of IPI+NIVO was feasible and no surgery-associated adverse events were attributed to (neo-)adjuvant therapy. 18/20 patients had to stop early due to grade 3/4 toxicities. Neo-adjuvant IPI+NIVO reduced tumor load in 8/10 patients (3 pCR, 4 near-pCRs [minimal remaining micrometastases], 1 pPR [75% reduction], 1 SD and 1 PD). To date, after a median follow-up of 45 weeks (range 13-74), none of the responders in the neoadjuvant arm has relapsed. Relapse was observed for both non-responders within the neo-adjuvant arm and for 3 patients within the adjuvant arm. TCR sequencing and MHC tetramer-based analysis to compare the induction and expansion of tumor (neo-)antigen-specific T cell responses between both treatment arms are underway and will be presented. Conclusions: The combination of IPI+NIVO in the (neo-)adjuvant treatment setting for high risk stage III melanoma patients is feasible and induces very frequent responses. At the same time, severe grade 3/4 toxicity is more frequent than expected from stage IV melanoma patient study data. These results indicate that IPI+NIVO is a promising combination for neo-adjuvant treatment in stage III melanoma. Adjusted combination schemes are currently tested in the phase 2 OpACIN-neo trial, with the aim of reducing toxicity while preserving efficacy. Clinical trial information: NCT02437279.

9502 Background: Neoadjuvant therapy (NT) for pts with clinical stage III melanoma remains an active area of research interest. Recent NT trial data demonstrates that achieving a pathologic complete response (pCR) correlates with improved relapse-free (RFS) and overall survival (OS). Checkpoint inhibitor (CPI) NT with either high or low dose ipilimumab and nivolumab regimens produces a high pCR rate of 30-45% but with grade 3-4 toxicity rate of 20-90%. In metastatic melanoma (MM), the combination of nivo with rela (anti Lymphocyte Activation Gene-3 antibody) has demonstrated a favorable toxicity profile and responses in both CPI-naïve and refractory MM. We hypothesized that NT with nivo + rela will safely achieve high pCR rates and provide insights into mechanisms of response and resistance to this regimen. Methods: We conducted a multi-institutional, investigator-initiated single arm study (NCT02519322) enrolling pts with clinical stage III or oligometastatic stage IV melanoma with RECIST 1.1 measurable, surgically-resectable disease. Pts were enrolled at 2 sites and received nivo 480mg IV with rela 160mg IV on wks 1 and 5. Radiographic response (RECIST 1.1) was assessed after completion of NT; surgery was conducted at wk 9 and specimens were assessed for pathologic response per established criteria. Pts received up to 10 additional doses of nivo and rela after surgery, with scans every 3 mo to assess for recurrence. The primary study objective was determination of pCR rate. Secondary objectives included safety, radiographic response by RECIST 1.1, event-free survival (EFS), RFS, and OS analyses. Blood and tissue were collected at baseline, at day 15, day 28, and at surgery for correlative analyses. Results: A total of 30 pts (19 males, median age 60) were enrolled with clinical stage IIIB/IIIC/IIID/IV (M1a) in 18/8/2/2 pts, respectively. 29 pts underwent surgery; 1 pt developed distant metastatic disease while on NT. pCR rate was 59% and near pCR ( < 10% viable tumor) was 7% for a major pathologic response (MPR, pCR + near pCR) of 66%. 7% of pts achieved a pPR (10-50% viable tumor) and 27% pNR (≥50% viable tumor). RECIST ORR was 57%. With a median follow up of 16.2 mos, the 1 -year EFS was 90%, RFS was 93%, and OS was 95%. 1-year RFS for MPR was 100% compared to 80% for non-MPR pts (p = 0.016). There were no treatment related gr 3/4 AEs that arose during NT; 26% of pts had a gr 3/4 AE that began during adjuvant treatment. Conclusions: Neoadjuvant and adjuvant treatment with nivo and rela achieved high pCR and MPR rates with a favorable toxicity profile in the neoadjuvant and adjuvant settings. Pts with MPR had improved outcomes compared to non-MPR pts. Translational studies to discern mechanisms of response and resistance to this combination are underway. Clinical trial information: NCT02519322.

e21570 Background: Advancements in systemic therapy have reduced recurrence, and the adoption of nodal surveillance in place of dissection has reduced morbidity for patients with Stage III melanoma. The objective of this study was to describe the timing and pattern of recurrence in stage III melanoma patients and evaluate the impact of adjuvant treatment and nodal surveillance. Methods: A multicenter retrospective chart review of patients with pathologically confirmed Stage III cutaneous melanoma seen at either the Juravinski Cancer Centre or Walker Family Cancer Centre in Ontario, Canada from January 1, 2017 to December 31, 2019. Results: There were 137 patients with Stage III melanoma: 18% IIIA, 22% IIIB, 52% IIIC, and 8% Stage IIID as per the 8th American Joint Committee on Cancer (AJCC) 2018 staging system. 103 (75%) patients had sentinel lymph node biopsy (SLNB) only as part of initial surgical therapy, 6 (4%) had SLNB with completion dissection, and 25 (18%) had upfront radical nodal dissection. 67 (49%) patients received adjuvant therapy, of which 50 (74%) had immunotherapy, 17 (25%) received BRAF-targeted therapy, and 1 (1%) had interferon. 54 (39%) patients developed recurrent disease, with a median time to recurrence of 8.5 months (IQR: 4.3-14.9). The recurrence rates were 63% in patients who did not have adjuvant treatment and 37% in those who had adjuvant therapy, with a median time-to-recurrence of 7.5 and 9.0 months respectively. There were 30 (56%) loco-regional recurrences and 24 (44%) distant recurrences. Of the patients with loco-regional recurrence, 26 (87%) had SLNB only compared to 4 (13%) who had upfront or completion dissection. 12 (24%) patients recurred while on adjuvant treatment (7 distant recurrences and 5 loco-regional recurrences), and 8 (13%) patients recurred following completion of adjuvant treatment (5 distant recurrences and 3 loco-regional recurrences). Recurrences were detected by patients, clinicians, CT and nodal US surveillance in 43%, 20%, 28% and 9% of cases, respectively. The majority of loco-regional recurrence was detected clinically (67%) rather than by radiologic surveillance (33%). Of the 30 loco-regional recurrences, 24 underwent surgical resection of the recurrence, 4 had subsequent systemic therapy without surgery, 1 had intra-tumoral injections and 1 had no treatment. Conclusions: Recurrences in Stage III melanoma occur early, often within a year, with higher rates of loco-regional rather than distant disease. Recurrence rates were lower in those who received adjuvant therapy, but the majority of recurrences were detected by patients or clinicians, including loco-regional recurrences in patients who had SLNB only despite surveillance nodal US.

Metastatic Rcc

Until recently, the sole treatment for patients with nonmetastatic renal cell carcinoma (RCC) was nephrectomy followed by observation. As metastatic RCC (mRCC) remains largely incurable (5-year survival rate ∼12%), adjuvant treatment, with potential to prevent/delay disease recurrence, is needed. In November 2017, sunitinib was approved in the USA as the first adjuvant therapy for patients at high risk for recurrent RCC postnephrectomy based on results from the S-TRAC trial. Patients eligible for adjuvant treatment have no evidence of disease and may be less willing to tolerate side effects. Therefore, proactive adverse event management is critical for keeping patients on adjuvant treatment and requires understanding the subtle differences in the adverse event profile of sunitinib in the adjuvant versus metastatic RCC setting.

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).
