651 Background: The introduction of immune checkpoint inhibitors (ICPI) has led to a paradigm change in the management of metastatic Renal Cell Carcinoma (mRCC). Prospective trials focused on ICPI treatment in first- or second-line. The aim of this analysis was to evaluate the benefit of ICPI across different treatment lines. Methods: This is a single center retrospective study from the Medical University of Vienna which included all mRCC patients who received ICPIs in various treatment lines. Overall response rates (ORR), progression free survival (PFS) and overall survival (OS) were evaluated for the entire cohort and by treatment line. Results: Between January 2014 and October 2019, a total of 113 patients received ICPIs. Ninety-four patients were eligible for full evaluation (83% clear cell and 17% non-clear cell). 26.8%, 61.6% and 14.8% were classified good, intermediate and poor IMDC-risk, respectively. 59%, 20% and 21% were treated with ICPI monotherapy, dual ICPI therapy and ICPI + tyrosine kinase inhibitor, respectively. ORR, median PFS and median OS for the entire cohort was 39.4%, 9.67 months (95%CI: 6.9-12.4 months) and 23.6 months (95%CI: 13.3-33.9 months), respectively. The ORR by treatment line was: 33% in first-line (9 patients), 40.4%, in second- (42 patients), 35% in third- (20 patients) and 43.5% in fourth and beyond-fourth-line (23 patients). The median PFS by treatment line was: 8.6 months, 10.3 months, 7.9 months and 7.23 months, respectively. The median OS was not reached (NR) in first-line and 26.2 months, 18.1 months and 20.7 months in second-, third-, and fourth and beyond- ICPI treatment line, respectively. The global OS for the whole patient cohort calculated from diagnosis of metastasis was 80 months (CL 95%: 50.5 – 109.5 months). Conclusions: ICPIs are active in all treatment lines and should also be offered in heavily pre-treated patients, who have not had access in earlier treatment lines.

Improved Outcomes

Immune checkpoint inhibitors (ICIs) such as nivolumab and ipilimumab have improved outcomes in metastatic renal cell carcinoma (mRCC) patients, but they are also associated with immune-related adverse events (irAEs). As observed in melanoma, we hypothesized that patients experiencing an autoimmune reaction directed against the tissue of origin may be more likely to benefit from ICI. Specifically, we asked whether patients with immune-related acute interstitial nephritis (irAIN) exhibited improved outcomes. Using Kidney Cancer Explorer (KCE), a data portal and i2b2-based central database for clinical, pathological and experimental genetic data, we systematically identified all patients with mRCC at UT Southwestern Medical Center (UTSW) from 2014–2018 who received at least one dose of ICI. More recent cases were identified through a provider query. We extracted creatinine (Cr) values at baseline and over the entirety of each patient ICI treatment course using KCE. Patients with ≥ 1.5-fold Cr increase over baseline were investigated. The likelihood of irAIN was determined based on the work-up (biopsy, if available), or by clinical criteria (timing of kidney injury, exclusion of other etiologies, treatment with immunosuppressants and response). We identified 177 mRCC patients who received at least one dose of ICI, 36 of whom had ≥ 1.5-fold increase in Cr over baseline while on treatment. Of those, two had biopsy-proven irAIN and one was clinically diagnosed, resulting in an incidence of 1.7%. One additional biopsy-proven case past 2018 was identified through a provider query, for a total of four patients. Two received combination nivolumab and ipilimumab in the first line, whereas the remaining received nivolumab after first line therapy. irAIN onset ranged from 1.5 to 12 months. All four patients stopped ICI with recovery of renal function, at least partially, three after receiving systemic steroids. Notably, all four patients had a deep response. In conclusion, irAIN is a rare event, but it may portend a higher likelihood of response. One possible explanation is antigenic overlap between normal renal tubular cells and tumor cells.

Immune checkpoint inhibitors have radically changed the treatment approach to metastatic renal cell carcinoma (mRCC). In the present article, we reported and discussed the available data with immunocombinations in mRCC, offering new perspectives in the treatment landscape of these patients. We discussed the main results of pivotal clinical trials of immune checkpoint inhibitors in the treatment of mRCC. Moreover, we discussed novel immuno-based treatments currently under investigation in ongoing clinical trials. Renal cell carcinoma is a particularly immunogenic tumor and immunotherapy is a pivotal treatment approach. A wide series of clinical trials is exploring novel promising immunocombinations in patients with renal cell carcinoma.

316 Background: Immune checkpoint inhibitors (ICI) have demonstrated impressive activity in metastatic clear-cell renal cell carcinoma (ccRCC) and have become standard treatment options in this setting. Data supporting the effectiveness of ICI based therapy in non-clear cell RCC (nccRCC) is more limited. Methods: We performed a retrospective analysis using the International Metastatic RCC Database Consortium (IMDC). Patients with nccRCC were classified into 3 groups based on first-line therapy: ICI based therapy (in monotherapy or in combination), vascular endothelial growth factor targeted therapy (VEGF-TT) monotherapy, or mammalian target of rapamycin (mTOR) inhibitor monotherapy. Primary outcome was overall survival (OS). Secondary outcomes were time to treatment failure (TTF) and objective response rate (ORR). We used Kaplan-Meier method to compare OS and TTF between treatment groups and Cox proportional hazards models to adjust for prognostic covariates. Results: We identified 1181 patients with nccRCC. In first-line, 78.2% received VEGF-TT, 15.8% mTOR inhibitors, and 5.5% ICI based therapy, of which 41.5% in monotherapy, 30.8% doublet-ICIs and 27.7% an ICI combined with VEGF-TT. Median OS in the ICI group was 28.6 months, compared to 19.2 and 12.6 in the VEGF-TT and mTOR groups, respectively. Median TTF was 6.9 months vs. 5.1 and 3.9 and ORR was 25% vs. 17.8% and 5.8% in the ICI, VEGF-TT and mTOR groups, respectively. After adjusting for IMDC risk group, histological subtype, and age, the hazard ratio (HR) for OS was 0.58 (95% CI 0.35-0.94, p=0.03) for ICI vs. VEGF-TT and 0.48 (95% CI 0.29-0.80, p=0.005) for ICI vs. mTOR. Conclusions: In advanced nccRCC, first-line ICI based treatment appears to be associated with improved OS compared to VEGF and mTOR targeted therapy. These results need to be confirmed in prospective randomized trials. [Table: see text]
