330 Background: Avelumab is a fully human anti‒PD-L1 IgG1 antibody with promising efficacy and safety in patients (pts) with metastatic urothelial carcinoma (mUC). To further characterize the clinical activity of avelumab in mUC, we report a planned interim pooled analysis of 2 cohorts from a large phase 1b trial (NCT01772004). Methods: Pts with mUC progressed after platinum-based therapy or cisplatin-ineligible, and unselected for tumor PD-L1 expression, received avelumab 10 mg/kg (1 h IV) Q2W. Response was assessed every 6 wks by independent review per RECIST v1.1. Endpoints included objective response rate (ORR), duration of response (DOR), progression-free survival (PFS), overall survival (OS), safety (NCI CTCAE v4.0), and tumor PD-L1 expression (clone 73-10). Results: As of Mar 19, 2016, 241 pts received avelumab for a median of 8 wks (range 2-80); median follow-up was 7.3 mos (range 0-18.2). Primary tumor sites were upper tract (renal pelvis/ureter [23.7%]) and lower tract (bladder/urethra [76.3%]). 95.4% of pts had progressed on prior platinum therapy, and 63.4% had received ≥ 2 prior lines for advanced disease (range 0-6). In 153 pts with ≥ 6 mos follow-up, confirmed ORR was 17.6% (95% CI 12.0-24.6) with 9 complete responses and 18 partial responses; 24/27 (88.9%) were ongoing. Median DOR was not reached, and the 24-wk DOR rate was 92.0% (95% CI 71.6, 97.9). 36 pts had stable disease as best response (disease control rate 41.2%). Median PFS was 6.4 wks (95% CI 6.1-11.4), and median OS was 7.0 mos (95% CI 5.6-11.1). Based on a ≥ 5% PD-L1 staining cutoff in evaluable pts with PD-L1+ (n = 56) and PD-L1– (n = 75) tumors, ORR was 25.0% (95% CI 14.4-38.4) vs 14.7% (95% CI 7.6-24.7; p = 0.178). Treatment-related adverse events (TRAE) of any grade occurring in ≥ 10% of pts were infusion-related reaction (22.8%) and fatigue (12.0%). 7.5% had a grade ≥ 3 TRAE; fatigue (1.2%)/asthenia (0.8%) occurred in > 1 pt. 28 pts (11.6%) had an immune-related TRAE (grade ≥ 3 in 2.5%). There was 1 treatment-related death (pneumonitis). Conclusions: Avelumab is well tolerated and shows promising clinical activity, including durable responses, in pts with mUC, regardless of tumor PD-L1 expression status. Follow-up is ongoing. Clinical trial information: NCT01772004.

166 Background: Avelumab, a human anti-PD-L1 IgG1 monoclonal antibody, is approved for treatment of metastatic Merkel cell carcinoma (US and EU) and advanced urothelial carcinoma progressed on platinum therapy (US). Here, we report updated phase 1b data for avelumab in patients (pts) with previously treated mesothelioma. Methods: Pts with unresectable pleural or peritoneal mesothelioma whose disease had progressed after platinum and pemetrexed therapy received avelumab 10 mg/kg IV Q2W until progression, unacceptable toxicity, or withdrawal. Tumors were assessed every 6 wks (RECIST 1.1). Endpoints included objective response rate (ORR), progression-free survival (PFS), overall survival (OS), and adverse events (AEs; NCI CTCAE v4.0). Results: As of Dec 31, 2016, 53 pts were treated and followed for a median of 24.8 mos (range 16.8–27.8). Median age was 67 y (range 32–84). Pts had received a median of 2 prior lines of therapy (range 1–8). Confirmed ORR was 9.4% (95% CI 3.1–20.7; complete response in 1.9%, partial response in 7.5%). In pts with 1 (n = 18), 2 (n = 15) or ≥3 (n = 20) prior lines of therapy, ORR was 5.6%, 13.3% and 10.0% respectively. Median duration of response was 15.2 mos (95% CI 11.1–not estimable). 26 pts (49.1%) had stable disease as best response and the disease control rate was 58.5%. Median PFS was 4.1 mos (95% CI 1.4–6.2) and the 6-mo PFS rate was 38.0% (95% CI 24.2–51.7). Median OS was 10.9 mos (95% CI 7.5–21.0) and the 12-mo OS rate was 45.9% (95% CI 31.9–58.8). In evaluable pts with PD-L1+ (n = 16) and PD-L1− (n = 27) tumors (≥5% tumor cell cutoff), ORR was 18.8% (95% CI 4.0–45.6) and 7.4% (95% CI 0.9–24.3), and the 6-mo PFS rate was 37.5% (95% CI 14.1–61.2) and 42.0% (95% CI 23.1–59.8). 43 pts (81.1%) had a treatment-related (TR)AE, most commonly ( > 10%) infusion-related reaction (35.8%; all grade 1/2), chills (15.1%), fatigue (15.1%) and pyrexia (11.3%). 5 pts (9.4%) had a grade ≥3 TRAE. 14 pts (26.4%) had an immune-related AE, which was grade ≥3 in 3 pts (5.7%; pneumonitis, colitis, and type 1 diabetes mellitus). No treatment-related deaths occurred. Conclusions: Avelumab showed clinical activity and acceptable safety in pts with previously treated mesothelioma. Clinical trial information: NCT01772004.

e16006 Background: FTD/TPI, an antimetabolite, is approved for treatment of refractory mGEC. This study sought to determine whether the combination of FTD/TPI with IRI (“TASIRI”) was safe and effective in mGEC previously treated with FP. Methods: This investigator‐initiated, multicenter, open‐label, single-dose level, single‐arm phase 1b study enrolled pts with mGEC previously treated with at least one line of FP containing regimen. FTD/TPI was given at 25 mg/m2 twice daily on days 1 to 5 with 180 mg/m2 IRI on day 1 of a 14‐day cycle. The primary endpoint was progression-free survival at six months (mo) (PFS-6). The aim was to show an improvement of PFS-6 from 15% to at least 30% based on historical controls. Results: At the time of data-cutoff (03Feb2021), 23 pts were screened and ultimately 20 pts were treated. The study met its primary endpoint. With a median follow-up of 9.8 mo (range 0.7 – 17), 8 pts are still on treatment and 4 pts have died. PFS-6 is 53.9% (lower limit of 95% CI: 28%). Median PFS and overall survival are 6.9 mo and not reached, respectively. At the time of data-cutoff, data were available for 13 pts with measurable disease by RECIST criteria and at least 1 on-treatment scan. Of those, 11 had stable disease and 2 had progressive disease as best response (5 pts had tumor shrinkage < 30%), therefore the disease control rate was 84.6%. The most common any grade (G) treatment related adverse events (TRAE) were nausea (n = 14, 70%), diarrhea (n = 9, 45%), and fatigue (n = 8, 40%). G3-4 TRAE in > 5% of pts were anemia (17%) and neutropenia (9%). 2 serious TRAE were reported: G4 febrile neutropenia (n = 1) and G3 hypotension (n = 1). There was no G5 TRAE. Conclusions: The combination of TASIRI showed encouraging clinical activity with a meaningful improvement in PFS-6 compared to historic controls. TASIRI was well tolerated and no new safety signals were seen. TASIRI warrants further investigation for patients with refractory mGEC and limited treatment options. Updated results with longer follow-up will be presented at the meeting. Clinical trial information: NCT04074343.

4072 Background: Combining an immune checkpoint inhibitor with a targeted antiangiogenic agent may leverage complementary mechanisms of action for treatment of advanced/metastatic (a/m) hepatocellular carcinoma (HCC). Avelumab is a human anti–PD-L1 IgG1 antibody with clinical activity in various tumor types; axitinib is a tyrosine kinase inhibitor selective for VEGF receptors 1/2/3. VEGF Liver 100 (NCT03289533) is a phase 1b study evaluating safety and efficacy of avelumab + axitinib in treatment-naive patients (pts) with HCC; interim results are reported here. Methods: Eligible pts had confirmed a/m HCC, ≥1 measurable lesion, a fresh or archival tumor specimen, ECOG PS ≤1, and Child-Pugh class A. Pts received avelumab 10 mg/kg IV Q2W + axitinib 5 mg orally BID until progression, unacceptable toxicity, or withdrawal. Endpoints included safety and objective response (RECIST v1.1; modified [m] RECIST for HCC). Results: Interim assessment was performed after a minimum follow up of 6 months based on the released study data set (clinical cut-off date: Aug 1, 2018). As of the cut-off date, 22 pts (median age: 68.5 y) were treated with avelumab (median: 20.0 wk) and axitinib (median: 19.9 wk). The most common grade 3 treatment-related adverse events (TRAEs) (≥10% of patients) were hypertension (50.0%) and hand-foot syndrome (22.7%); no grade 4/5 TRAEs were reported. Immune-related AEs (irAEs) (≥10% of pts) were hypothyroidism (31.8%) and hyperthyroidism (13.6%). No grade ≥3 irAEs were reported; no pts discontinued treatment due to TRAEs or irAEs. Based on Waterfall plot calculations, tumor shrinkage was observed in 15 (68.2%) and 16 (72.7%) pts by RECIST and mRECIST, respectively. ORR was 13.6% (95% CI, 2.9%-34.9%) and 31.8% (95% CI, 13.9%-54.9%) by RECIST and mRECIST, respectively. OS data were immature at data cutoff. Conclusions: The preliminary safety of avelumab + axitinib in HCC is manageable and consistent with the known safety profiles of avelumab and axitinib when administered as monotherapies. This study demonstrates antitumor activity of the combination in HCC. Follow-up is ongoing. Clinical trial information: NCT03289533. [Table: see text]

TPS4589 Background: Accumulating evidence supports MET as a therapeutic target in urothelial carcinoma. Activated MET can promote angiogenesis and tumor growth by upregulating VEGF and may play a role in urothelial carcinoma pathogenesis. Cabozantinib inhibits primarily VEGFR2 and MET pathways. Cabozantinib has been approved by the FDA for the treatment of progressive metastatic medullary thyroid cancer, is in Phase 3 trials for metastatic castration-resistant prostate cancer and has demonstrated clinical activity in multiple solid tumors. We previously reported that shed MET levels in serum and urine of patients with urothelial carcinoma correlate with stage, presence of visceral metastases and urinary source and that cabozantinib is effective in reversing HGF-driven urothelial carcinoma cell growth and invasion. These data support the evaluation of cabozantinib in patients with metastatic urothelial carcinoma. Methods: This is a phase II study of oral cabozantinib 60mg daily given continuously in 28-day cycles. There are three study cohorts: [1] metastatic urothelial carcinoma [2] bone only metastatic urothelial carcinoma [3] metastatic non-urothelial carcinoma of the bladder, urethra, ureter, or renal pelvis. A maximum of 55 subjects will be enrolled. Up to 45 patients will be accrued to cohort 1.The remainder will be enrolled on exploratory cohorts 2 & 3. A two-stage single-arm phase II design will be employed. The primary objective is to determine the objective response rate in patients with metastatic urothelial carcinoma who have progressed on prior chemotherapy. Secondary objectives include progression free survival, safety and toxicity, and overall survival. Exploratory objectives include tumor tissue Met expression, shed MET levels in serum and urine, immune subsets, genetic biomarkers, molecular markers of angiogenesis and circulating tumor cells, correlation with clinical response parameters. Finally we will explore treatment evaluation with FDG and NaF PET/CT compared to standard imaging. This study is supported by the Cancer Therapy Evaluation Program (CTEP).

367 Background: Avelumab* (MSB0010718C) is a fully human anti-PD-L1 IgG1 antibody being investigated in multiple clinical trials. We report safety and clinical activity of avelumab as a second-line therapy in patients (pts) with metastatic urothelial carcinoma (mUC) based on level of PD-L1 expression (NCT01772004). Methods: Pts with mUC unselected for PD-L1 expression received avelumab at 10 mg/kg Q2W by IV infusion until confirmed progression, unacceptable toxicity, or any criterion for withdrawal occurred. Tumors were assessed every 6 wks (RECIST 1.1). Best overall response rate (ORR) and progression-free survival (PFS) were evaluated. Adverse events (AEs) were graded by NCI-CTCAE v4.0. PD-L1 expression was assessed by immunohistochemistry. Results: As of 19 Mar 2015, 44 pts (30 men, 14 women) with mUC were treated with avelumab (median 13 wks [range 2-28]) and followed for a median of 3.5 mo (range 3.0-5.0). Median age was 68y (range 30-84), ECOG performance status was 0 (43.2%) or 1 (56.8%), and pts had received a median of 2 prior therapies (range 1- ≥ 4). Treatment-related treatment-emergent AEs (TR-TEAEs) of any grade occurred in 26 pts (59.1%); those occurring ≥ 10% were grade 1/2 infusion-related reactions (8 [18.2%]) and fatigue (7 [15.9%]). One pt had grade 3 asthenia. There were no treatment-related deaths. ORR was 15.9% (7 pts; 95% CI: 6.6, 30.1) with 1 CR and 6 PRs; 6 responses were ongoing at data cutoff. Stable disease (SD) was observed in 19 pts (42.3%) and disease-control rate (CR+PR+SD) was 59.1%. PD-L1 expression was evaluable in 32 pts. Using a ≥ 5% cutoff (10/32 [31.3%] were PD-L1+), ORR was 40.0% in PD-L1+ pts (4/10) vs 9.1% in PD-L1– pts (2/22; p= 0.060). PFS rate at 12 wks was 70.0% (95% CI: 32.9, 89.2) in PD-L1+ pts vs 45.5% (95% CI 22.7, 65.8) in PD-L1− pts. Conclusions: Avelumabshowed an acceptable safety profile and had clinical activity in pts with mUC. There was a trend towards higher ORR and prolonged PFS rate at 12 wks in pts with PD-L1+ mUC. Further analyses of PD-L1 expression and clinical activity of avelumab in UC are ongoing. *Proposed INN. Clinical trial information: NCT01772004.

4528 Background: Avelumab, a fully human anti‒PD-L1 IgG1 antibody, has shown promising efficacy and safety in 2 cohorts of patients (pts) with mUC. We now report updated data from a pooled analysis of these pts with mUC from JAVELIN Solid Tumor (NCT01772004) and further characterize the clinical activity of avelumab in this disease. Methods: Pts with mUC progressed after platinum-based therapy or cisplatin ineligible received avelumab 10 mg/kg 1-hour IV Q2W. Tumors were assessed every 6 weeks by independent review (RECIST v1.1). Endpoints included objective response rate (ORR), duration of response (DOR), progression-free survival (PFS), overall survival (OS), safety (NCI CTCAE v4.0), and tumor PD-L1 expression. Results: As of Jun 9, 2016, 249 pts had received avelumab for a median of 12 weeks (range 2-92) and were followed up for a minimum of 6 weeks. Primary tumor site was upper tract (renal pelvis/ureter) in 23.3% and lower tract (bladder/urethra) in 76.7%. 242 pts (97.2%) had progressed on prior platinum therapy and 7 pts (2.8%) were platinum naive. In 161 post-platinum pts with ≥6 months of follow-up, confirmed ORR was 17.4% (95% CI 11.9-24.1; complete response in 6.2%) with a disease control rate of 39.8%. Response was ongoing in 23/28 responders at data cut (82.1%; median DOR not reached), and the 24-week durable response rate was 92.3% (95% CI 72.6-98.0). Responses occurred across PD-L1 expression levels tested (≥5% and < 5% tumor cell‒staining [25.4% and 13.2%]). In all post-platinum pts (n = 242), median PFS was 6.6 weeks (95% CI 6.1-11.6), median OS was 7.4 months (95% CI 5.7-10.3) and 6-month OS rate was 54.9 (95% CI 47.7-61.7). Treatment-related adverse events (TRAE) of any grade occurred in 166/249 pts (66.7%); most common (≥10%) were infusion-related reaction (22.9%, all grade ≤2) and fatigue (16.1%). 21 pts (8.4%) had a grade ≥3 TRAE (fatigue [1.6%] and asthenia [0.8%] in > 1 pt). 34 pts (13.7%) had an immune-related AE (grade ≥3 in 2.4%). There was 1 treatment-related death (pneumonitis). Conclusions: Avelumab was well tolerated and showed durable responses in heavily pretreated pts with mUC, irrespective of tumor PD-L1 expression status. Clinical trial information: NCT01772004.

4524 Background: In the open-label, single-arm, phase 2 CheckMate 275 trial, objective response rate (ORR) for patients (pts) with metastatic urothelial carcinoma (mUC) with nivolumab (NIVO) was 20.4% with minimum follow-up of 21.3 mo. Here, we report updated efficacy and safety data with minimum follow-up of 33.7 mo. Methods: Pts with platinum-resistant locally advanced or metastatic urothelial carcinoma received NIVO 3 mg/kg until disease progression or unacceptable toxicity. The primary endpoint was ORR by blinded independent review committee (BIRC) by RECIST v1.1 (including duration of response [DOR]). Secondary endpoints included progression-free survival (PFS) by BIRC, overall survival (OS), and ORR per investigator. Efficacy was evaluated in all treated pts and by tumor PD-L1 expression. Safety and PFS by investigator were exploratory endpoints. Results: ORR by BIRC was 20.7% (95% CI 16.1–26.1) including 18 (7%) complete responses (CR; with 1 additional CR since the last report; Table). ORR per investigator was similar (24.8%). Median DOR by BIRC was 20.3 mo (95% CI 11.5–31.3). Of 56 pts with best overall response (BOR) of CR or partial response (PR), 59% had a DOR ≥12 mo. Median PFS (mPFS) was 1.9 mo per BIRC (95% CI 1.9–2.3; Table) and 2.0 mo per investigator (95% CI 1.9–2.5). Median OS (mOS) was 8.6 mo (95% CI 6.1–11.3; Table). 12, 24, and 36-mo OS rates were 40%, 30%, and 22%. While efficacy was numerically higher in pts with tumor PD-L1 expression ≥1%, efficacy was observed in all pts (Table). Any-grade treatment-related adverse events occurred in 69% of pts (grade 3–4, 25%), mostly (59%) within the first 3 mo of initiating therapy. Conclusions: With long-term follow-up from CheckMate 275, NIVO continues to provide durable antitumor activity in pts with mUC. No new safety signals were noted. Clinical trial information: NCT02387996. [Table: see text]

PURPOSE We assessed the safety and efficacy of cabozantinib and nivolumab (CaboNivo) and CaboNivo plus ipilimumab (CaboNivoIpi) in patients with metastatic urothelial carcinoma (mUC) and other genitourinary (GU) malignances. PATIENTS AND METHODS Patients received escalating doses of CaboNivo or CaboNivoIpi. The primary objective was to establish a recommended phase II dose (RP2D). Secondary objectives included objective response rate (ORR), progression-free survival (PFS), duration of response (DoR), and overall survival (OS). RESULTS Fifty-four patients were enrolled at eight dose levels with a median follow-up time of 44.6 months; data cutoff was January 20, 2020. Grade 3 or 4 treatment-related adverse events (AEs) occurred in 75% and 87% of patients treated with CaboNivo and CaboNivoIpi, respectively, and included fatigue (17% and 10%, respectively), diarrhea (4% and 7%, respectively), and hypertension (21% and 10%, respectively); grade 3 or 4 immune-related AEs included hepatitis (0% and 13%, respectively) and colitis (0% and 7%, respectively). The RP2D was cabozantinib 40 mg/d plus nivolumab 3 mg/kg for CaboNivo and cabozantinib 40 mg/d, nivolumab 3 mg/kg, and ipilimumab 1 mg/kg for CaboNivoIpi. ORR was 30.6% (95% CI, 20.0% to 47.5%) for all patients and 38.5% (95% CI, 13.9% to 68.4%) for patients with mUC. Median DoR was 21.0 months (95% CI, 5.4 to 24.1 months) for all patients and not reached for patients with mUC. Median PFS was 5.1 months (95% CI, 3.5 to 6.9 months) for all patients and 12.8 months (95% CI, 1.8 to 24.1 months) for patients with mUC. Median OS was 12.6 months (95% CI, 6.9 to 18.8 months) for all patients and 25.4 months (95% CI, 5.7 to 41.6 months) for patients with mUC. CONCLUSION CaboNivo and CaboNivoIpi demonstrated manageable toxicities with durable responses and encouraging survival in patients with mUC and other GU tumors. Multiple phase II and III trials are ongoing for these combinations.

<b><i>Introduction:</i></b> Combining an immune checkpoint inhibitor with a targeted antiangiogenic agent may leverage complementary mechanisms of action for the treatment of advanced/metastatic hepatocellular carcinoma (aHCC). Avelumab is a human anti-PD-L1 IgG1 antibody with clinical activity in various tumor types; axitinib is a selective tyrosine kinase inhibitor of vascular endothelial growth factor receptors 1, 2, and 3. We report the final analysis from VEGF Liver 100 (NCT03289533), a phase 1b study evaluating safety and efficacy of avelumab plus axitinib in treatment-naive patients with aHCC. <b><i>Methods:</i></b> Eligible patients had confirmed aHCC, no prior systemic therapy, ≥1 measurable lesion, Eastern Cooperative Oncology Group performance status ≤1, and Child-Pugh class A disease. Patients received avelumab 10 mg/kg intravenously every 2 weeks plus axitinib 5 mg orally twice daily until progression, unacceptable toxicity, or withdrawal. Endpoints included safety and investigator-assessed objective response per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and modified RECIST (mRECIST) for HCC. <b><i>Results:</i></b> Twenty-two Japanese patients were enrolled and treated with avelumab plus axitinib. The minimum follow-up was 18 months as of October 25, 2019 (data cutoff). Grade 3 treatment-related adverse events (TRAEs) occurred in 16 patients (72.7%); the most common (≥3 patients) were hypertension (<i>n</i> = 11 [50.0%]), palmar-plantar erythrodysesthesia syndrome (<i>n</i> = 5 [22.7%]), and decreased appetite (<i>n</i> = 3 [13.6%]). No grade 4 TRAEs or treatment-related deaths occurred. Ten patients (45.5%) had an immune-related AE (irAE) of any grade; 3 patients (13.6%) had an infusion-related reaction (IRR) of any grade, and no grade ≥3 irAE and IRR were observed. The objective response rate was 13.6% (95% CI: 2.9–34.9%) per RECIST 1.1 and 31.8% (95% CI: 13.9–54.9%) per mRECIST for HCC. <b><i>Conclusion:</i></b> Treatment with avelumab plus axitinib was associated with a manageable toxicity profile and showed antitumor activity in patients with aHCC.

9000 Background: In the randomized phase 3 CheckMate 9LA trial (NCT03215706), first-line NIVO + IPI combined with 2 cycles of chemo significantly improved overall survival (OS), progression-free survival (PFS), and objective response rate (ORR) vs chemo alone (4 cycles). Clinical benefit was observed regardless of programmed death ligand 1 (PD-L1) expression level and histology. Here we report data with 2 years’ minimum follow-up from this study. Methods: Adult patients (pts) with stage IV / recurrent NSCLC, ECOG performance status ≤ 1, and no known sensitizing EGFR/ALK alterations were stratified by PD-L1 (< 1% vs ≥ 1%), sex, and histology (squamous vs non-squamous) and were randomized 1:1 to NIVO 360 mg Q3W + IPI 1 mg/kg Q6W + chemo (2 cycles; n = 361) or chemo alone (4 cycles; n = 358). Pts with non-squamous NSCLC in the chemo-alone arm could receive pemetrexed maintenance. The primary endpoint was OS. Secondary endpoints included PFS and ORR by blinded independent central review, and efficacy by different PD-L1 levels. Safety was exploratory. Results: At a minimum follow-up of 24.4 months for OS (database lock: Feb 18, 2021), pts treated with NIVO + IPI + chemo continued to derive OS benefit vs chemo, with a median OS of 15.8 months vs 11.0 months, respectively (HR, 0.72 [95% CI, 0.61–0.86]); 2-year OS rates were 38% vs 26%. Median PFS with NIVO + IPI + chemo vs chemo was 6.7 months vs 5.3 months (HR, 0.67 [95% CI, 0.56–0.79]); 8% and 37% of pts who had disease progression received subsequent immunotherapy, respectively. ORR was 38% with NIVO + IPI + chemo vs 25% with chemo. Similar clinical benefit with NIVO + IPI + chemo vs chemo was observed in all randomized pts and across the majority of subgroups, including by PD-L1 expression level (Table) or histology. Any grade and grade 3–4 treatment-related adverse events were reported in 92% and 48% of pts in the NIVO + IPI + chemo arm vs 88% and 38% in the chemo arm, respectively. Conclusion: With 2 years’ minimum follow-up, first-line NIVO + IPI + chemo demonstrated durable survival and benefit versus chemo in pts with advanced NSCLC; no new safety signals were identified. Clinical trial information: NCT03215706. [Table: see text]
