Purpose: This prospective, randomized, controlled phase III trial assessed high-dose bolus interleukin-2 (IL-2) postoperatively in patients with high-risk renal cell carcinoma (RCC). Patients and Methods: Eligibility requirements were resected locally advanced (LA; T3b-4 or N1–3) or metastatic (M1) RCC, no prior systemic therapy, and excellent organ function. Randomized assignment was to one course of IL-2 (600,000 U/kg every 8 hours on days 1 to 5 and days 15 to 19 [maximum 28 doses]) or observation. The study was designed and powered to show an improvement in predicted 2-year disease-free survival (DFS) from 40% for the observation group to 70% for the treatment group. The accrual goal was 68 patients with LA disease, with 34 patients per treatment arm. Metastasectomy patients were to be analyzed separately because of their unpredictable natural history. Results: Sixty-nine patients were enrolled onto the study (44 LA and 25 M1 patients). Toxic effects of IL-2 were as anticipated; no unexpected serious adverse events or treatment-related deaths occurred. Early closure occurred when an interim analysis determined that the 30% improvement in 2-year DFS could not be achieved despite full accrual. Sixteen of 21 LA patients receiving IL-2 experienced relapse, compared with 15 of 23 patients in the observation arm (P = .73); in the LA group, three deaths occurred in the IL-2 arm, and five deaths occurred in the observation arm (P = .38). Analysis including metastasectomy patients made no difference in DFS or overall survival. Conclusion: One course of high-dose bolus IL-2, though feasible, did not produce the ambitious clinically meaningful benefit anticipated when administered postoperatively to patients with resected high-risk RCC.

PURPOSE SORCE is an international, randomized, double-blind, three-arm trial of sorafenib after surgical excision of primary renal cell carcinoma (RCC) found to be at intermediate or high risk of recurrence. PATIENTS AND METHODS We randomly assigned participants (2:3:3) to 3 years of placebo (arm A), 1 year of sorafenib followed by 2 years of placebo (arm B), or 3 years of sorafenib (arm C). The initial sorafenib dose was 400 mg twice per day orally, amended to 400 mg daily. The primary outcome analysis, which was revised as a result of external results, was investigator-reported disease-free survival (DFS) comparing 3 years of sorafenib versus placebo. RESULTS Between July 2007 and April 2013, we randomly assigned 1,711 participants (430, 642, and 639 participants in arms A, B, and C, respectively). Median age was 58 years, 71% of patients were men, 84% had clear cell histology, 53% were at intermediate risk of recurrence, and 47% were at high risk of recurrence. We observed no differences in DFS or overall survival in all randomly assigned patients, patients with high risk of recurrence, or patients with clear cell RCC only. Median DFS was not reached for 3 years of sorafenib or for placebo (hazard ratio, 1.01; 95% CI, 0.83 to 1.23; P = .95). We observed nonproportional hazards; the restricted mean survival time (RMST) was 6.81 years for 3 years of sorafenib and 6.82 years for placebo (RMST difference, 0.01 year; 95% CI, −0.49 to 0.48 year; P = .99). Despite offering treatment adaptations, more than half of participants stopped treatment by 12 months. Grade 3 hand-foot skin reaction was reported in 24% of participants on sorafenib. CONCLUSION Sorafenib should not be used as adjuvant therapy for RCC. Active surveillance remains the standard of care for patients at intermediate or high risk of recurrence after nephrectomy and is the appropriate control of our current international adjuvant RCC trial, RAMPART.

576 Background: In the phase III S-TRAC trial, adjuvant sunitinib (SU) prolonged disease-free survival (DFS) vs placebo (PBO) in patients with locoregional renal cell carcinoma at high risk of recurrence after nephrectomy (median 6.8 vs 5.6 y; hazard ratio [HR] 0.76, 95% confidence interval [CI] 0.59–0.98; P= 0.03). An exploratory analysis evaluated associations between single nucleotide polymorphisms (SNPs) in angiogenesis-related genes and clinical outcomes in S-TRAC. Methods: Prospectively collected blood samples were genotyped for 10 SNPs and 1 insertion/deletion mutation with TaqMan assays. DFS was compared with a log-rank test for each SNP genotype in SU vs PBO arms and between SNP genotypes within each arm. P-values are unadjusted for multiplicity comparison. Results: Of 615 patients, 286 (142 SU; 144 PBO) were analyzed. There were generally no genotype frequency deviations from the Hardy-Weinberg equilibrium, but linkage disequilibrium was seen between VEGFA rs699947 and rs833061 on chromosome 6 (D′ = 1.000, r2 = 0.979). Longer DFS was observed with SU vs PBO for VEGFR1 rs9554320 C/C (median: not reached [NR] vs 5.56 y; HR 0.44, 95% CI 0.21–0.91; P= 0.023), VEGFR2 rs2071559 T/T (median: NR vs 4.47 y; HR 0.46, 95% CI 0.23–0.90; P= 0.020), and eNOS rs2070744 T/T (median: 7.07 vs 3.44 y; HR 0.53, 95% CI 0.30–0.94; P= 0.028), with a trend for VEGFR1 rs9582036 A/A (median: NR in both arms; P= 0.054) and SH3GL2 rs10963287 C/T (median: NR vs 5.35 y; P= 0.088). Shorter DFS was observed for VEGFR1 rs9582036 C/A vs C/C in the SU, PBO, and combined arms ( P< 0.05); for A/A vs common, the association was only seen in the SU arm ( P= 0.022). VEGFR1 rs9554320 A/C was associated with shorter DFS vs A/A in the PBO ( P= 0.038) and combined arm ( P= 0.006), with a trend in the SU arm ( P= 0.051). VEGFR2 rs1870377 T/T was associated with longer DFS vs A/A in the combined arms, but not in the PBO arm (n = 7 with A/A genotype in the SU arm precluded statistical tests). Conclusions: Correlations between common VEGFR1 and VEGFR2 SNPs and longer DFS with SU suggest germline SNPs are predictive of improved outcomes with adjuvant SU. Due to the exploratory nature of this analysis, prospective validation studies are needed to confirm these findings. Clinical trial information: NCT00375674.

4507 Background: PROTECT (NCT01235962) evaluated the efficacy and safety of pazopanib (PAZ) versus placebo in patients (pts) with locally advanced renal cell carcinoma (RCC) post nephrectomy. Methods: 1538 pts with resected pT2 (high grade), pT3 or greater clear cell RCC were randomly assigned to PAZ or placebo for 1 year. The starting dose (800 mg) following treatment of 403 pts was lowered to 600 mg to improve tolerability and primary endpoint was changed to disease-free survival (DFS) with PAZ 600 (N = 1135). Primary analysis was performed after 350 DFS events in intent-to-treat (ITT) PAZ 600, and DFS follow-up analysis was performed after an additional 12 months. Secondary endpoints included DFS with ITT PAZ 800 and ITT ALL, and safety. Results: Disease characteristics were similar between arms. The primary analysis results of DFS ITT 600 were not significant [HR: 0.862; 95% CI, 0.699, 1.063; p = 0.165] (Table). The secondary endpoint of DFS in ITT PAZ 800 and ITT ALL yielded 31% and 20% risk reduction, respectively. Updated DFS analysis in ITT 600 showed a higher HR with longer follow up. Increased ALT and AST were the most common adverse events leading to treatment discontinuation in the PAZ 600 (ALT 16% and AST 5%) and PAZ 800 (ALT 18% and AST 7%) groups. Conclusions: The study did not meet the primary DFS endpoint in ITT 600; however, a 31% decrease in the risk of recurrence was observed in ITT 800. The safety profiles in the 600 mg and 800 mg groups were similar and consistent with PAZ prior experience. Clinical trial information: NCT01235962. [Table: see text]

Purpose The Cytokine Working Group conducted a randomized phase III trial to determine the value of outpatient interleukin-2 (IL-2) and interferon alfa-2b (IFN) relative to high-dose (HD) IL-2 in patients with metastatic renal cell carcinoma. Patients and Methods Patients were stratified for bone and liver metastases, primary tumor in place, and Eastern Cooperative Oncology Group performance status 0 or 1 and then randomly assigned to receive either IL-2 (5 MIU/m2 subcutaneously every 8 hours for three doses on day 1, then daily 5 days/wk for 4 weeks) and IFN (5 MIU/m2 subcutaneously three times per week for 4 weeks) every 6 weeks or HD IL-2 (600,000 U/kg/dose intravenously every 8 hours on days 1 through 5 and 15 to 19 [maximum 28 doses]) every 12 weeks. Results One hundred ninety-two patients were enrolled between April 1997 and July 2000. Toxicities were as anticipated for these regimens. The response rate was 23.2% (22 of 95 patients) for HD IL-2 versus 9.9% (nine of 91 patients) for IL-2/IFN (P = .018). Ten patients receiving HD IL-2 were progression-free at 3 years versus three patients receiving IL-2 and IFN (P = .082). The median response durations were 24 and 15 months (P = .18), and median survivals were 17.5 and 13 months (P = .24). For patients with bone or liver metastases (P = .001) or a primary tumor in place (P = .040), survival was superior with HD IL-2. Conclusion This randomized phase III trial provides additional evidence that HD IL-2 should remain the preferred therapy for selected patients with metastatic renal cell carcinoma.

Free Survival

High-dose interleukin-2 (HD IL-2) was approved in the 1990s after demonstrating durable complete responses (CRs) in some patients with metastatic melanoma (mM) and metastatic renal cell carcinoma (mRCC). Patients who achieve this level of disease control have also demonstrated improved survival compared with patients who progress, but limited data are available describing the long-term course. The aim of this study was to better characterize long-term survival following successful HD IL-2 treatment in patients with no subsequent systemic therapy. Eleven HD IL-2 treatment centers identified patients with survival ≥5 years after HD IL-2, with no subsequent systemic therapy. Survival was evaluated from the date of IL-2 treatment to June 2017. Treatment courses consisted of 2 1-week cycles of HD IL-2. Patients were treated with HD IL-2 alone, or HD IL-2 followed by local therapy to achieve maximal response. 100 patients are reported: 54 patients with mM and 46 patients with mRCC. Progression-free survival (PFS) after HD IL-2 ranges from 5+ years to 30+ years, with a median follow-up of 10+ years. 27 mRCC and 32 mM are alive ≥10 years after IL-2. Thus, a small subset of patients with mM and mRCC achieve long-term PFS (≥5 years) after treatment with HD IL-2 as their only systemic therapy. The ability of HD IL-2 therapy to induce prolonged PFS should be a major consideration in studies of new immunotherapy combinations for mM and mRCC.
