461 Background: HD IL-2, an immunotherapy, is a standard of care for a select group of patients (pts) with mRCC. Generally objective response (OR) rates, i.e. complete response (CR) + partial response (PR), of 16-20% are discussed with pts, but not disease stabilization (SD). Recent data suggest that cancer immunotherapy may improve survival without inducing OR. Thus, treatment with HD IL-2 may provide survival benefit to an additional group of pts not experiencing OR, but only SD as the best response. Here we report CB ( OR+SD), and specifically report outcomes of cc mRCC pts experiencing SD as the best response, on treatment with HD IL-2. Methods: All sequential cc mRCC pts treated with HD IL-2 at the University of Utah Huntsman Cancer Institute from 2000-2012 were included. Pts were evaluated for best response, progression-free survival (PFS), time to next treatment (TNT) and overall survival (OS). Two practitioners independently reviewed HD IL-2 response with discrepancies adjudicated by a third reviewer. Results: 85 pts, 79% male, were identified with a median age of 56 (range 32-76) years. Pts belonged to the following MSKCC risk categories: 11 (13%) good, 70 (82%) intermediate, and 4 (5%) poor risk. A CR was identified in 9 (11%), PR in 5 (6%), SD in 26 (31%), progressive disease (PD) in 38 (45%), and unknown/not evaluable (NE) in 7 (8%) pts; yielding a clinical benefit in 40 (47%) pts. The median PFS, TNT, and OS in these individual groups of pts are compared in the table. Conclusions: A clinical benefit of HD IL-2 was achieved in nearly half of all clear cell mRCC pts. OS was not significantly different in OR and SD groups. Even though OR favorably determine outcomes, SD is also an important response criterion, and may be discussed during counseling pts for treatment with HD IL-2. [Table: see text]

562 Background: Initial safety results from the phase 3b/4 CheckMate 374 study showed that flat-dose nivolumab (NIVO) at 240 mg every 2 wk (Q2W) had a consistent safety profile across patients (pts) with clear cell and non-clear cell advanced RCC. We report updated safety and first disclosure of efficacy for pts with non-clear cell RCC (nccRCC) in CheckMate 374. Methods: Eligible pts in this cohort were adults with advanced or metastatic nccRCC who received 0–3 prior systemic therapies. Pts received NIVO 240 mg IV Q2W for ≤24 mo or until confirmed progression, unacceptable toxicity, or withdrawal of consent. Pts who benefited after 24 mo continued treatment according to the standard of care. The primary endpoint was incidence of high-grade immune-mediated adverse events (IMAEs). Exploratory endpoints included overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and duration of response (DOR). Results: In CheckMate 374, 44 pts had nccRCC. Histological subtypes included papillary (n = 24), chromophobe (n = 7), unclassified (n = 8), and other (n = 5). Most pts with nccRCC (66%) were treatment-naïve. After a median follow-up of 11.1 mo, median OS was 16.3 mo (95% confidence interval [CI] 9.2–not estimable [NE]). OS was similar regardless of baseline PD-L1 expression. ORR was 13.6% (95% CI 5.2–27.4). One pt had complete response (chromophobe histology) and 5 pts had partial response (2 pts with papillary and 1 pt each with chromophobe, collecting duct, and unclassified histology). Median DOR was 10.2 mo (95% CI 5.6–NE). Median PFS was 2.2 mo (95% CI 1.8–5.4). The 1-year PFS rate was 14% (95% CI 5–27). No new safety concerns were identified. No treatment-related grade 5 AEs or grade 3–4 IMAEs were reported. Conclusions: Clinically meaningful antitumor activity was observed in the first prospective study of NIVO monotherapy in nccRCC. Responses were observed in several histological subtypes. The safety profile of flat-dose NIVO at 240 IV Q2W is consistent with the initial outcomes reported from this study and across the NIVO program. Clinical trial information: NCT02596035.

Line Setting

e16570 Background: The CheckMate 9ER trial showed that the combination of nivolumab and cabozantinib (nivo-cabo) in first line setting for treatment of mRCC was superior to sunitinib in terms of objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) and led to its FDA approval. We report outcomes of cohort of patients with mRCC treated with nivo-cabo in the salvage setting. Methods: We retrospectively reviewed 17 patients with mRCC treated at Winship Cancer Institute who progressed through at least one line of prior therapy. These patients were then treated with either sequences: [1] cabozantinib and then add nivolumab upon progression (n = 8) and [2] nivolumab/ipilimumab or nivolumab and then add cabozantinib upon progression (n = 9) with two with nivolumab and ipilimumab. Median PFS and OS rates, and clinical benefit (defined as complete response or partial response, or stable disease) were described. Results: Thirteen patients had clear cell histology and four patients had non-clear cell histology. For sequence [1], the mPFS for cabozantinib alone was 9.9 months and combination of nivolumab added to cabozantinib was 8.9 months. For sequence [2], the mPFS for nivolumab with or without ipilimumab was 5.9 months and combination of cabozantinib added to nivolumab was 10.4 months. The 12-month OS rate was 88% for sequence [1] and 89% for sequence [2]. The 24-month, OS rate was 50% for sequence [1] and 89% for sequence [2]. 5/8 (63%) patients in sequence [1] and 7/9 (78%) patients in sequence [2] had clinical benefit. 3/8 (37.5%) patients in sequence [1] and 2/9 (22%) patients in sequence [2] experienced immune-related adverse effects such as hypothyroidism (grade II for two patients), pneumonitis (grade II), hepatic transaminase elevations (grade II), and pancreatitis (grade III). No patients in sequence [1] needed dose reduction in cabozantinib once nivolumab was added. 3/9 (33%) patients had dose reduction in cabozantinib in sequence [2] due to diarrhea. Conclusions: Nivo-cabo demonstrates activity in the salvage setting but there is still need to understand the optimal sequencing of both agents in the treatment of mRCC. Outcomes from this combination treatment are to be further validated from ongoing phase III trial, PDIGREE (NCT03793166).

BackgroundThe indoleamine 2,3-dioxygenase (IDO) pathway is a key counter-regulatory mechanism that, in cancer, is exploited by tumors to evade antitumor immunity. Indoximod is a small-molecule IDO pathway inhibitor that reverses the immunosuppressive effects of low tryptophan (Trp) and high kynurenine (Kyn) that result from IDO activity. In this study, indoximod was used in combination with a checkpoint inhibitor (CPI) pembrolizumab for the treatment for advanced melanoma.MethodsPatients with advanced melanoma were enrolled in a single-arm phase II clinical trial evaluating the addition of indoximod to standard of care CPI approved for melanoma. Investigators administered their choice of CPI including pembrolizumab (P), nivolumab (N), or ipilimumab (I). Indoximod was administered continuously (1200 mg orally two times per day), with concurrent CPI dosed per US Food and Drug Administration (FDA)-approved label.ResultsBetween July 2014 and July 2017, 131 patients were enrolled. (P) was used more frequently (n=114, 87%) per investigator’s choice. The efficacy evaluable population consisted of 89 patients from the phase II cohort with non-ocular melanoma who received indoximod combined with (P).The objective response rate (ORR) for the evaluable population was 51% with confirmed complete response of 20% and disease control rate of 70%. Median progression-free survival was 12.4 months (95% CI 6.4 to 24.9). The ORR for Programmed Death-Ligand 1 (PD-L1)-positive patients was 70% compared with 46% for PD-L1-negative patients. The combination was well tolerated, and side effects were similar to what was expected from single agent (P).ConclusionIn this study, the combination of indoximod and (P) was well tolerated and showed antitumor efficacy that is worth further evaluation in selected patients with advanced melanoma.

In recent years, the management of metastatic renal cell carcinoma (mRCC) has been revolutionized by the advent of targeted therapies. Multitargeted kinase inhibitors (such as sunitinib, sorafenib, pazopanib, and axitinib), the vascular endothelial growth factor inhibitor bevacizumab, and mammalian target of rapamycin inhibitors (such as everolimus and temsirolimus) have become the standard of care for the palliation of metastatic disease. Unfortunately, cumulative toxicities and the lack of marked benefits have prevented the combined use of most molecularly targeted agents. Selected patients with mRCC benefit from immunotherapy, as subsets of patients can experience long-term disease remission or complete response with high-dose interleukin-2. In order to optimize the value of immunotherapy, improvements in the selection of drugs and combinations with novel immunomodulatory agents must be pursued.

4122 Background: The mammalian target of rapamycin (mTOR) signaling pathway is involved in the pathogenesis of neuroendocrine tumors (NET). Everolimus (RAD001), an oral mTOR inhibitor, has antitumor activity in patients (pts) with advanced NET. In this open-label, multicenter, phase II study (RAMSETE), the safety and efficacy of everolimus monotherapy was evaluated in pts with advanced nonsyndromic, nonpancreatic NET. Methods: Pts with advanced (unresectable or metastatic), progressive, nonsyndromic, nonpancreatic NET received everolimus (10 mg/day) as monotherapy. The primary endpoint was objective response rate (proportion of pts with best overall complete response [CR] or partial response [PR] per RECIST v1.0) by central radiologic review. A secondary endpoint included progression-free survival (PFS). Results: By database soft lock (December 1, 2011), 73 pts from 16 European clinics received everolimus (median duration of treatment: 193 days). Fifty-five (75%) pts discontinued; reasons included disease progression (n=23), adverse events (AEs [n=23]), withdrawal of consent (n=4), death (n=3), and protocol deviation (n=2). In the per protocol population (N=60), 32 (53%) pts received prior antineoplastic therapy. The best response by central review was stable disease in 55%. By local review, 3 (5%) pts had a PR, with SD in 39 (65%) pts. Median PFS by central review was 185 days (95% CI: 158-255). Median PFS by local investigator review was 285 days (95% CI: 231-not estimable). 69 (95%) pts reported treatment-related AEs of any grade, including rash (n=28; 38%), diarrhea (n=20; 27%), mucosal inflammation (n=18; 25%), and decreased appetite (n=17; 23%). Treatment-related grades 3 and 4 AEs and serious AEs were reported by 27 (37%) and 18 (25%) pts, respectively. Conclusions: In this open-label trial of everolimus in pts with advanced, nonsyndromic, extrapancreatic NET, a high rate of disease stabilization was achieved after prior tumor progression with favorable median PFS. This study further supports efficacy of everolimus in types of NET other than those studied in RADIANT-3 (pancreatic NET) and RADIANT-2 (NET associated with carcinoid syndrome).

4040 Background: In the phase 2 CheckMate 142 trial, NIVO + low-dose IPI had robust, durable clinical benefit and was well tolerated as 1L therapy for MSI-H/dMMR mCRC (median follow-up 13.8 months [mo; range, 9–19]; Lenz et al. Ann Oncol 2018;29:LBA18). Longer follow-up is presented here. Methods: Patients (pts) with MSI-H/dMMR mCRC and no prior treatment for metastatic disease received NIVO 3 mg/kg Q2W + low-dose IPI 1 mg/kg Q6W until disease progression or discontinuation. The primary endpoint was investigator-assessed (INV) objective response rate (ORR) per RECIST v1.1. Results: In 45 pts with median follow-up of 29.0 mo, ORR (95% CI) increased to 69% (53–82) (Table) from 60% (44.3–74.3); complete response (CR) rate increased to 13% from 7%. The concordance rate of INV and blinded independent central review was 89%. Median duration of response (DOR) was not reached (Table). Median progression-free survival (PFS) and overall survival (OS) were not reached, and 24-mo rates were 74% and 79%, respectively (Table). Nineteen pts discontinued study treatment without subsequent therapy. An analysis of tumor response post discontinuation will be presented. Ten (22%) pts had grade 3–4 treatment-related adverse events (TRAEs); 3 (7%) had grade 3–4 TRAEs leading to discontinuation. Conclusions: NIVO + low-dose IPI continued to show robust, durable clinical benefit with a deepening of response, and was well tolerated with no new safety signals identified with longer follow-up. NIVO + low-dose IPI may represent a new 1L therapy option for pts with MSI-H/dMMR mCRC. Clinical trial information: NTC02060188 . [Table: see text]

8544 Background: Metastatic melanoma is associated with a poor survival rate. High response rates have been reported for both chemotherapy and biochemotherapy. To assess whether adding interferon-a (IFN) ± interleukin-2 (IL-2) to chemotherapy is advantageous, a published data meta-analysis of trials of biochemotherapy versus chemotherapy has been performed. Methods: Standard published data meta-analysis methods were used to assess response rates (partial, complete and objective (i.e. partial+complete)) and overall survival (OS), with odds ratios (OR) and 95% confidence intervals (CI) calculated. The only subgroup analysis performed was by type of immunotherapy, with trials divided according to the type of immunotherapy given in the biochemotherapy arm - IFN or IFN+IL-2. Results: Data were available from 18 trials (11 trials of chemotherapy ± IFN and 7 of trials chemotherapy ± IFN+IL-2). Nearly 2500 patients were included in the analysis, with 555 responses and 2,039 deaths observed. There was a clear benefit for biochemotherapy for partial response (OR=0.67, CI=0.54–0.83, p=0.0002), complete response (0.50, 0.35–0.73, p=0.0003) and objective response (0.60, 0.49–0.73, p<0.00001). For objective response, these benefits were significant for both the IFN (0.60, 0.46–0.79, p=0.0002) and IFN+IL2 (0.60, 0.45–0.78, p=0.00002) subgroups. In contrast, there was no benefit on OS (0.99, 0.91–1.08, p=0.9), and there was also evidence of heterogeneity of treatment effect between the individual trials (p=0.006). Conclusions: This meta-analysis shows that biochemotherapy clearly improves response rates, but this does not appear to translate into a survival benefit. Single agent chemotherapy is considered the standard of care for the majority of patients receiving treatment for advanced melanoma outside a clinical trial, and the result of this meta-analysis shows no reason to change this. No significant financial relationships to disclose.

487 Background: HD IL-2 is associated with an objective response rate of 16-20% with durability of response in select mRCC patients. HD IL-2 is also associated with significant toxicity including vascular leak syndrome and inflammatory side effects. Few predictive markers can identify patients likely to respond to HD IL-2. Methods: Patients treated with HD IL-2 at the University of Utah Huntsman Cancer Institute from 2000 to 2012 with clear cell mRCC were evaluated. Grade of toxicities during HD IL-2 treatment were collected based on provider documentation in the electronic health record. Rates of adverse events (AEs) and overall survival stratified grade 3 AEs were evaluated by Kaplan-Meier survival estimates and Cox proportional hazards models. All AEs were graded per common terminology criteria version 4. Grade 3 rigors were defined as severe rigors requiring opioids. Results: A total of 85 patients were included with a median age of 56 years (range 32-76 years) and 79% (n = 67) were male. Patients belonged to the following MSKCC risk categories: 11 (13%) good, 70 (82%) intermediate, and 4 (5%) poor risk. The mean total dose received was 1097 MIU (range: 160 – 3048 MIU). The prevalence of grade 3 AEs is presented in the table. Median survival of patients with ≥grade 3 rigors after HD IL-2 administration was 1501 days vs 533 days for those without (p = 0.0005, HR 2.54). Presence of rigors was also associated with a significant improvement in progression free survival, time to next treatment and response rates. No other AEs predicted response to HD IL-2. Conclusions: Presence of grade 3 rigors predicts improved survival during HD IL-2 therapy. Notably, grade 3 fever was rarely observed because of our institutional protocol of routinely using scheduled antipyretics to diminish fevers. [Table: see text]

671 Background: The full dose of cabo is 60 mg, but some pts are treated with a reduced dose with the clinical anticipation of adverse events (AEs). We compared AEs and CO in mRCC pts treated with full versus reduced dose cabo. Methods: We performed a retrospective analysis of 65 mRCC pts treated with cabo at Winship Cancer Institute from 2016-2018. CO were measured by overall survival (OS), progression-free survival (PFS), and objective response (OR). OS and PFS were measured from first dose of cabo to date of death and clinical or radiographic progression, respectively. OR was defined as partial response (PR) or complete response (CR) per RECISTv1.1. AEs were collected from clinic notes. Univariate analysis (UVA) of association between AEs and CO was performed using logistic regression model. Results: Most pts were males (68%) and the median age was 63 years. Most (79%) had clear cell RCC (ccRCC) and the majority were IMDC intermediate (59%) or poor (39%) risk. Most pts (68%) received 60 mg and 48% of these pts underwent a dose reduction for AEs. Nearly all pts (95%) who started on a reduced dose experienced AEs, compared to 66% for pts treated with 60 mg. OR rate was similar for pts on 60 mg (18%) and pts on a reduced dose (19%). The median survival was comparable in pts treated with 60 mg and pts treated with a reduced dose (10.9 vs. 8.8 months, p=0.92 for OS and 5.6 vs. 5.1 months, p=0.23 for PFS) per Kaplan Meier estimation. AEs, particularly gastrointestinal (GI) AEs, were associated with significantly lower chance of OR (Table). Conclusions: CO may be comparable in mRCC pts treated with full versus reduced dose of cabo, but a reduced dose of cabo may not be associated with decreased AEs. GI side effects may be a poor prognostic factor in mRCC pts treated with cabo. Larger studies are warranted to validate these findings. [Table: see text]
