5070 Background: IO combination therapies [including IOIO and IO/vascular endothelial growth factor inhibitor (IOVE) combinations] in mRCC have been approved based on registration clinical trials that have strict eligibility criteria. The clinical outcomes of trial ineligible patients who are treated with first-line IOIO or IOVE combinations are unknown. Methods: Metastatic RCC patients treated with first-line IOIO or IOVE were retrospectively deemed ineligible for clinical trials (according to commonly used inclusion/exclusion criteria in IO trials) if they had a Karnofsky performance status (KPS) < 70%, no clear-cell component, brain metastases, hemoglobin (Hb) < 9 g/dL, eGFR < 40 mL/min, platelet count of < 100,000/mm3, and/or neutrophil count < 1500/mm3. Time to treatment failure (TTF) and overall survival (OS) were calculated from time of starting first-line IO therapy. Results: Overall, 26% (155/592) of patients in the International mRCC Database Consortium (IMDC) were deemed ineligible for clinical trials by the above criteria. Baseline characteristics are listed in Table. The reasons for ineligibility were: no clear-cell component (34%, 53/155), Hb < 9g/dL (28%, 44/155), eGFR < 40 mL/min (19%, 30/155), brain metastases (19%, 29/155), KPS < 70% (14%, 21/155), platelet < 100,000/mm3 (3%, 4/155) and neutrophil count < 1500/mm3 (0%, 0/155). Between ineligible versus eligible patients, the response rate, median TTF and median OS of first-line IOIO or IOVE was 34% vs 46% (p = 0.02), 4.2 vs 9.7 months (p < 0.01), and 25.3 vs 44.4 months (p < 0.01), respectively. When adjusted by the IMDC prognostic categories, the HR for death between trial ineligible and trial eligible patients was 1.50 (95% CI 1.05-2.14). Conclusions: The number of patients that are ineligible for clinical trials is substantial and their outcomes are inferior. These data may guide patient counselling and specific trials addressing the unmet needs of protocol ineligible patients are warranted. [Table: see text]

353 Background: Clinical trials have strict eligibility criteria to maintain internal validity. These criteria exclude many patients to whom the trial results are later applied to in clinical practice. Patients that do not meet eligibility criteria are poorly characterized. Methods: mRCC patients treated with VEGF targeted therapy were retrospectively deemed ineligible for clinical trials (according to commonly used inclusion/exclusion criteria) if they had a Karnofsky Performance Status (KPS) < 70%, brain metastases, non-clear cell histology, hemoglobin ≤ 9 g/dL, creatinine > 2x the upper limit of normal, platelet count of < 100x103/uL, neutrophil count < 1500/mm3 or corrected calcium ≤ 12 mg/dL. Results: 894/2076 (43%) patients were deemed ineligible for clinical trials by the above criteria. Between ineligible versus eligible patients, the response rate, median progression free survival (PFS) and median overall survival of first-line targeted therapy were 21% vs 29%, 5.2 vs 8.8 months and 14.5 vs 28.8 months (all p < 0.0001), respectively. Second-line PFS (if applicable) was 3.2 months in the trial ineligible vs 4.4 months in the trial eligible patients (p = 0.0074). When adjusted by the Heng et al prognostic categories, the hazard ratio for death between trial ineligible vs trial eligible patients was 1.621 (95% CI = 1.431–1.836, p < 0.0001). If only KPS, brain metastases and non-clear cell histology were used as exclusion criteria, 672 (32%) patients were excluded and the results were similar. Conclusions: The number of patients that are ineligible for clinical trials is high and their outcomes are inferior. Designing more inclusive clinical trials for this “ineligible” patient population are needed. [Table: see text]

4536 Background: Clinical trials have strict eligibility criteria that exclude many patients to whom the trial results are later extrapolated to in clinical practice. Methods: mRCC patients treated with VEGF targeted therapy were retrospectively deemed ineligible for clinical trials (according to commonly used inclusion/exclusion criteria) if they had a Karnofsky Performance Status (KPS) <70%, brain metastases, non-clear cell histology, hemoglobin<=9 g/dL, creatinine >2x the upper limit of normal, platelet count of <100x103/uL, neutrophil count <1500/mm3 or corrected calcium>=12 mg/dL. Results: 894/2076 (43%) patients were deemed ineligible for clinical trials by the above criteria.

Second-line PFS (if applicable) was 3.2 months in the trial ineligible vs 4.4 months in the trial eligible patients (p=0.0074). Patients who were excluded due to KPS<70, hemoglobin<=9 g/dL, calcium >=12, brain metastases, and non-clear cell histology, had a hazard ratio (HR) for death of 2.8 (95%CI 2.4-3.4), 1.8 (95%CI 1.4-2.2), 1.8 (95%CI 1.2-2.7), 1.4 (95%CI 1.1-1.8), and 1.4 (95%CI 1.1-1.7), respectively (all p<0.01). When adjusted by the Heng et al prognostic categories, the HR for death between trial ineligible vs trial eligible patients was 1.511 (95%CI=1.335-1.710, p<0.0001). Conclusions: The number of patients that are ineligible for clinical trials is high and their outcomes are inferior. Specific trials addressing the needs of protocol ineligible patients and assessing OS are required. [Table: see text]

315 Background: Combination therapy with nivolumab + ipilimumab (NIVO+IPI) has demonstrated long-term efficacy and tolerability for patients (pts) with previously untreated advanced renal cell carcinoma (aRCC). Most pivotal clinical trials in pts with aRCC have excluded pts with low Karnofsky performance status (KPS; < 70%). CheckMate 920 is a multi-arm, phase IIIb/IV, open-label clinical trial of NIVO+IPI treatment in pts enrolled in a community practice setting with aRCC and a high unmet medical need. We present safety and efficacy results for the cohort of pts with aRCC of any histology and KPS 50%–60% from CheckMate 920 (NCT02982954). Methods: Pts with previously untreated advanced/metastatic RCC and KPS 50%–60% received NIVO 3 mg/kg + IPI 1 mg/kg Q3W × 4 doses followed by 480 mg NIVO Q4W for ≤ 2 years or until disease progression/unacceptable toxicity. The primary endpoint was incidence of grade ≥ 3 immune-mediated adverse events (imAEs) within 100 days of last dose of study drug. Key secondary endpoints included progression-free survival (PFS) and objective response rate (ORR) by RECIST v1.1 (both per investigator). Exploratory endpoints included overall survival (OS). Results: Of 25 treated pts with KPS 50%–60%, 76% were men; median age was 67 years (range, 34–81). IMDC risk was favorable in 0%, intermediate in 32%, and poor in 68% of pts; 84% had clear cell and 16% had non-clear cell RCC histology. With a minimum follow-up of 25 months, median duration of therapy (95% CI) was 2.3 months (2.1–7.7) for NIVO and 2.1 months (2.1–2.1) for IPI. The median number of doses (range) received was 4 (1–27) for NIVO and 4 (1–4) for IPI; 76% of pts received ≥ 4 NIVO doses and 68% received all 4 IPI doses. The only grade 3–4 imAEs by category were hepatitis (4.0%) and adrenal insufficiency (4.0%). No grade 5 imAEs occurred. Overall, 4 (16%) pts discontinued due to any-grade adverse events (n = 1 each for elevated AST, malignant neoplasm progression, back pain, and acetabulum fracture). Of 18 evaluable pts, ORR was 33.3% (95% CI, 13.3–59.0); no pts had a complete response and 6 had partial response. Median time to objective response was 4.5 months (range, 2.5–24.7). Median duration of objective response was 20.6 months (range, 0.03+–24.2+). Median PFS was 4.6 months (95% CI, 2.5–14.8). Median OS was 15.6 months (95% CI, 5.3–25.1). Conclusions: NIVO+IPI demonstrated an acceptable safety profile and promising antitumor activity in pts with previously untreated aRCC and KPS 50%–60%. The combination was tolerated at a dose intensity similar to that observed in clinical trials conducted in pts with higher KPS (≥ 70%). These data support the value of NIVO+IPI in pts who may not be considered ideal candidates for this therapy and consequently may have limited treatment options.

326 Background: Patients with brain metastases from advanced RCC treated in the targeted therapy era are not well characterized. Methods: Data from patients with mRCC treated with targeted therapy were collected through the International mRCC Database Consortium from 6 centers. Results: One hundred six out of 705 (15%) patients with mRCC had brain metastases. Forty-seven patients had brain metastases at the start of first-line anti-VEGF therapy and the rest developed metastases during follow-up. Of the patients with brain metastases, 6%, 68%, and 26% were in the favorable, intermediate and poor prognosis groups, respectively, per the Heng et al JCO 2009 criteria. Ninety percent had cerebral metastases, 17% had cerebellar metastases, 40% had a Karnofsky performance status (KPS) <80%, and 81% had symptoms of brain metastases. The median largest size and number of brain metastases was 1.8 cm (range 0.2–6.6) and 1 (range 1–20), respectively. Patients were treated with first-line sunitinib (n=77), sorafenib (n=23), bevacizumab (n=5), and temsirolimus (n=1). Local disease treatment included whole brain radiotherapy (81%), stereotactic radiosurgery (25%), and neurosurgery (25%). The brain metastases of 59 patients were evaluable and based on the local treatment and/or targeted therapy achieved 7 (12%) complete responses, 23 (39%) partial responses, 14 (24%) patients with stable disease, and 15 (25%) patients with progressive disease in the brain metastases. Patients with more than 4 brain metastases vs. those with no more than 4 have an overall survival time from diagnosis of brain metastasis of 3.9 vs. 15.4 months (p=0.0051). Previous nephrectomy, sarcomatoid, and non-clear cell histology are not associated with development of brain metastases. On multivariable analysis, KPS<80% (p=0.0139), diagnosis to treatment with targeted therapy <1 year (p=0.0012), and higher number of brain metastases (p=0.0311) were associated with worse survival from diagnosis of brain metastases. Conclusions: In patients with brain metastases from RCC, KPS at start of therapy, diagnosis to treatment time and number of brain metastases may be prognostic factors for overall survival.

59 Background: An extremely small proportion of patients with cancer in the United States (US) enroll in clinical trials. While several barriers to trial accrual have been described, the geographic distribution and accessibility of clinical trial sites has not been comprehensively explored. Methods: ClinicalTrials.gov was queried to identify all active US clinical trials exploring first-line therapies for metastatic prostate cancer (PCa) on 9/16/2012. We evaluated the geographic distribution of trial sites and determined the relationship between the number of sites and the number of patients with advanced PCa per county and evaluated heterogeneity using Lorenz curves. We also estimated the minimum driving distance required to access a clinical trial site from each ZIP code in the continguous US; a distance >30 miles was defined as high travel burden consistent with prior studies. Results: We identified 958 sites associated with 42 PCa clinical trials (Table). The geographic distribution of clinical trial sites was very inhomogeneous with several states having only 1-2 trial sites. Among 3185 US counties, 2,669 (83.8%) had no clinical trials available for first-line treatment of metastatic PCa. Counties with larger populations of patients with advanced PCa had significantly higher numbers of clinical trial sites. For every 100 additional patients with advanced PCa per county, the number of available trial sites increased by 21.0% (95% CI: 16.5-25.7%). However, Lorenz curves indicated a high degree of inequality in trial accessibility (Gini index 0.71). Approximately 31% of the US population resided >30 miles from a PCa trial site. Conclusions: Clinical trials sites are poorly accessible, geographically, to a large subset of US PCa patients, a finding that likely contributes to dismal accrual. Innovative solutions are required to address geographic barriers to access. [Table: see text]

TPS268 Background: 5-fluorouracil (5FU), in combination with folates, is an established cornerstone of metastatic colorectal cancer (mCRC) treatment. All folates currently approved for mCRC need to be metabolically activated to [6R]-5,10-methylenetetrahydrofolic acid ([6R]-MTHF), the active thymidylate synthase co-substrate that potentiates the effect of 5FU. Arfolitixorin does not require multi-step metabolic activation, and may produce higher, and less inter- and intraindividually variable, concentrations of [6R]-MTHF than leucovorin. Methods: The phase III AGENT trial (NCT03750786) is a randomized, multicenter, parallel-group study comparing the efficacy of arfolitixorin versus leucovorin in mCRC patients treated with first-line 5FU, oxaliplatin, and bevacizumab. Patients are randomized (1:1) to the investigational arm (arfolitixorin + 5FU + oxaliplatin [ARFOX] + bevacizumab) or the comparator arm (leucovorin + 5FU + oxaliplatin [modified FOLFOX-6] + bevacizumab), and treated until disease progression based on RECIST 1.1 criteria. Recruitment is ongoing, and aims to randomize 440 patients in 18 months. Eligibility criteria include non-resectable mCRC; eligibility for 5FU, oxaliplatin, and bevacizumab therapy; ECOG PS 0 or 1. The study will be conducted across approximately 100 sites in Australia, Austria, Canada, France, Germany, Greece, Japan, Spain, Sweden, and USA. The primary endpoint is objective response rate. Key secondary endpoints are progression-free survival and duration of response. Additional secondary endpoints include overall survival, quality of life, safety and tolerability, and number of patients undergoing curative metastasis resection. A translational program will evaluate expression levels of several folate metabolism- and transportation-related genes in mCRC tumor biopsies to determine their relationship to treatment outcome. A broad array of genes will analyzed, including ATP-binding cassette C3 (ABCC3) transporter, methylenetetrahydrofolate dehydrogenase 2 (MTHFD2), proton-coupled folate transporter (PCFT), and serine hydroxymethyltransferase 1 (SHMT1). Interim data are expected in mid 2020. Clinical trial information: NCT03750786.

375 Background: The question regarding the benefit of a TKI rechallenge versus switch to an mTOR inhibitor (mTORi) in mRCC pts who responded to a previous line of TKI remains unanswered and is a common dilemma in clinical practice. We report results of a retrospective study to address this question. Methods: This study retrospectively investigated Duration of Treatment (DT), best radiological response (OR) and predictive factors in pts treated with either TKI-TKI or TKI-mTORi sequences for clear-cell mRCC. Eligibility criteria: 1 TKI in 1st line (L1) followed by another TKI or mTORi as 2nd line (L2). Prior immunotherapy was allowed but not intermediate lines with other drugs. Pts characteristics and Heng’s prognostic factors were collected at each line initiation. Response (resp) was classified with regard to DT and OR using 2 different definitions: def1 = Non Responders (NR): < 4months (m) + PD; Short-Term responders (STR): [4–6]m + SD/PR, Long-term Responders (LTR): >6m + SD/PR, and def2 = NR: < 4m + PD, STR: [4–12]m + SD/PR, LTR: >12m + SD/PR. Results: 127 pts from 7 European centers were retrospectively analyzed. Based on def1, resp to L1 was: LTR=93, STR=20, NR=14; among LTR pts, 54 received a L2=TKI and 39 a L2=mTORi. Based on def2, resp to L1 was: LTR=59, STR=53, NR=15; among LTR pts, 35 received a L2=TKI and 24 a L2=mTORi. Whether def1 or def2, resp (L1 and L2) was never related to Heng’s score. Among LTR pts at L1, 26 out of 54 were LTR after L2=TKI vs 18 out of 39 after L2=mTORi (p=0.85, Z-test) for def1 and 9 out of 35 were LTR after L2=TKI vs 6 out of 24 after L2=mTORi (p=0.95) for def2 (see table). For both def1 and def2, median DT was 7.2m and 6.9m for L2=TKI and L2=mTORi, respectively (p=0.86 and p=0.95, Log-Rank). Conclusions: Results suggest that long-term responders on 1st line TKI could benefit both from TKI and mTORi as 2nd line and there is no evidence to favor one sequence over the other.

4517 Background: Previous clinical trials of patients (pts) with aRCC, including CheckMate 214, have mostly excluded pts with brain metastases. However, antitumor activity in pts with brain metastases has been observed in pts with melanoma treated with NIVO 1 mg/kg + IPI 3mg/kg and pts with non-small cell lung cancer treated with NIVO 240 mg + IPI 1mg/kg. CheckMate 920 is an ongoing, phase 3b/4 clinical trial of NIVO + IPI treatment in pts with aRCC with a high unmet medical need. Here, we present the safety and efficacy interim results for the cohort of pts with brain metastases. Methods: Pts with previously untreated aRCC of any histology, with asymptomatic brain metastases (not on corticosteroids or receiving radiation), and Karnofsky performance status ≥70% were assigned to treatment with NIVO 3 mg/kg + IPI 1 mg/kg every 3 weeks for 4 doses, followed by NIVO 480 mg every 4 weeks. Pts were treated until disease progression, unacceptable toxicity, or for a maximum of 2 years. The primary endpoint was the incidence of high-grade immune-mediated adverse events (IMAEs). Key secondary endpoints included progression-free survival (PFS) and objective response rate (ORR) by RECIST v1.1 per investigator. Exploratory endpoints included additional safety analyses and overall survival (OS). Results: Overall, 28 patients were enrolled in the brain metastases cohort. With a minimum follow-up of 6.47 months, grade 3-4 IMAEs within 100 days of last dose were reported in 6 cases. The grade 3-4 IMAEs observed in ≥ 1 patient were diarrhea, colitis, diabetic ketoacidosis, immune-mediated hepatitis, hypophysitis, and rash of any type (n = 1 each). No treatment-related grade 5 IMAEs were reported. ORR by RECIST v1.1 per investigator in all treated subjects was 28.6% (95% CI 13.2–48.7). Median PFS in all treated subjects was 9.0 months (95% CI 2.9–not estimable [NE]). Median OS has not been reached (95% CI 13.1–NE). Conclusions: In pts with aRCC and brain metastases who are often excluded from clinical trials, NIVO + IPI treatment showed a safety profile consistent with previous reports of this dosing regimen, with encouraging antitumor activity. Clinical trial information: NCT02982954.
