    Abstract: 5598 Background: LEN is a multikinase inhibitor of vascular endothelial growth factor (VEGF) receptor 1−3, fibroblast growth factor receptor 1−4, platelet-derived growth factor receptor α, RET, and KIT. Pembro, an antibody targeting programmed cell death protein 1 (PD-1), prevents T cell deactivation. In addition to its antiangiogenic effects, LEN may act in part by preventing VEGF-mediated immune suppression, suggesting combination with pembro could improve its activity. We report results in pts with endometrial carcinoma from a phase Ib/II trial of LEN + pembro. Methods: In this multicenter, open-label study, pts had confirmed metastatic endometrial cancer that progressed after approved therapy, measurable disease, and ECOG performance status ≤ 1. Pts received oral LEN 20 mg/day plus pembro 200 mg intravenously every 3 weeks. Tumor assessments were by the investigator. The primary phase II endpoint was objective response rate (ORR) based on immune-related RECIST (irRECIST). Secondary endpoints included progression-free survival (PFS), disease-control rate (DCR; complete response [CR] + partial response [PR] + stable disease [SD]), clinical-benefit rate (CBR; CR + PR + durable SD), and duration of response (DOR), all by irRECIST, and safety. Results: 23 Pts enrolled (phase II: 21; phase Ib: 2); median age was 64 years (range: 51−80); 87% were white; and all had ≥ 1 prior anticancer therapy. Confirmed ORR was 48% (all PR). Median PFS and DOR were not estimable (NE; see table). All pts had a treatment-emergent adverse event (TEAE). The most common TEAEs were hypertension, fatigue, arthralgia, diarrhea, and nausea. Toxicities were manageable with dose interruption and/or modification and no new safety signals were found. Updated data will be presented. Conclusions: Promising efficacy was observed in pts receiving LEN + pembro. In addition, toxicities were generally expected and manageable with dose modification. These results warrant further study of LEN + pembro in pts with endometrial carcinoma. Clinical trial information: NCT02501096. [Table: see text]

    Abstract: 15 Background: Lenvatinib (LEN) is a multikinase inhibitor of VEGFR 1−3, FGFR 1−4, PDGFRα, RET, and KIT. Pembrolizumab (PEM), an anti-PD-1 antibody, is approved for first-line treatment of advanced melanoma (objective response rates [ORR], 21–34%). In preclinical studies, LEN decreased tumor-associated macrophage populations, increased CD8 + T cell infiltration, and augmented PD-1 inhibitor activity; thus, LEN is a rational combination partner for PEM. We report interim results of an ongoing phase 1b/2 trial of LEN + PEM in solid tumors, focusing on advanced melanoma. Methods: In this multicenter, open-label study, patients (pts) with measurable, confirmed, metastatic melanoma and ECOG PS ≤1 received oral LEN (20 mg/day) + PEM (200 mg Q3W, IV). Pts were not preselected for PD-L1 status. Tumor assessments were by investigator per immune-related RECIST (irRECIST). Phase 2 primary end point was ORR at 24 weeks (ORR WK24 ). Secondary end points included ORR, progression-free survival (PFS) and duration of response (DOR). Results: At data cutoff (March 1, 2018), 21 pts were enrolled: 14 (67%) were PD-L1+, 4 (19%) were PD-L1-; 3 (14%) not tested. 38% had ≥1 prior anticancer therapy. ORR WK24 was 47.6% (95% CI, 25.7–70.2). All pts had ≥1 treatment-related adverse event (TRAE). Grade 3 and 4 TRAEs occurred in 13 (62%) and 1 (5%; adrenal insufficiency) pts respectively. There were no fatal TRAEs. Most common any-grade TRAEs were fatigue (52%), decreased appetite (48%), diarrhea (48%), hypertension (48%), dysphonia (43%), and nausea (43%). Dose reduction and interruption due to TRAEs occurred in 13 (62%) and 10 (48%) pts, respectively. Conclusions: LEN + PEM was well-tolerated and had encouraging clinical activity. The combination may potentially improve on the antitumor activity of anti-PD-1 monotherapies, supporting further evaluation in advanced melanoma. Clinical trial information: NCT02501096.

    Abstract: Patients with advanced endometrial carcinoma have limited treatment options. We report final primary efficacy analysis results for a patient cohort with advanced endometrial carcinoma receiving lenvatinib plus pembrolizumab in an ongoing phase Ib/II study of selected solid tumors. METHODS Patients took lenvatinib 20 mg once daily orally plus pembrolizumab 200 mg intravenously once every 3 weeks, in 3-week cycles. The primary end point was objective response rate (ORR) at 24 weeks (ORR Wk24 ); secondary efficacy end points included duration of response (DOR), progression-free survival (PFS), and overall survival (OS). Tumor assessments were evaluated by investigators per immune-related RECIST. RESULTS At data cutoff, 108 patients with previously treated endometrial carcinoma were enrolled, with a median follow-up of 18.7 months. The ORR Wk24 was 38.0% (95% CI, 28.8% to 47.8%). Among subgroups, the ORR Wk24 (95% CI) was 63.6% (30.8% to 89.1%) in patients with microsatellite instability (MSI)–high tumors (n = 11) and 36.2% (26.5% to 46.7%) in patients with microsatellite-stable tumors (n = 94). For previously treated patients, regardless of tumor MSI status, the median DOR was 21.2 months (95% CI, 7.6 months to not estimable), median PFS was 7.4 months (95% CI, 5.3 to 8.7 months), and median OS was 16.7 months (15.0 months to not estimable). Grade 3 or 4 treatment-related adverse events occurred in 83/124 (66.9%) patients. CONCLUSION Lenvatinib plus pembrolizumab showed promising antitumor activity in patients with advanced endometrial carcinoma who have experienced disease progression after prior systemic therapy, regardless of tumor MSI status. The combination therapy had a manageable toxicity profile.

    Abstract: TPS707 Background: Based on findings from a randomized phase 2 study (Study 205), lenvatinib (LEN) + everolimus (EVE) was approved in the United States and European Union for patients (pts) with advanced RCC following 1 prior anti-angiogenic therapy. In that study, LEN 18 mg QD + EVE 5 mg QD significantly prolonged progression-free survival (PFS) compared with either monotherapy. In the LEN+EVE cohort, grades 3 and 4 treatment-emergent adverse events (TEAEs) occurred in 71% of pts. We report the design of an ongoing, multicenter, randomized, double-blind, phase 2 study (Study 218) to evaluate if a lower LEN starting dosage regimen provides similar efficacy with a better safety profile than LEN 18 mg + EVE 5 mg (NCT03173560). Methods: Eligible pts are aged ≥ 18 years with advanced clear cell RCC, 1 prior anti-VEGF therapy, ≥ 1 measurable target lesion per RECIST 1.1, a KPS score of ≥ 70, and prior nivolumab is allowed. Pts will receive LEN 18 mg or 14 mg QD + EVE 5 mg QD in 28-day cycles until disease progression, unacceptable toxicity, or withdrawal of consent. The LEN 14-mg dose will be escalated to 18 mg if no intolerable grade 2, or any grade ≥ 3 TEAEs requiring dose reduction occur in cycle 1. The primary endpoints are objective response rate (ORR) at week 24 (ORR 24W ) and the proportion of pts with intolerable grade 2 and any grade ≥ 3 TEAEs within 24 wks after randomization. Secondary endpoints include PFS and ORR. An estimated 306 pts will be randomized. Sample size is based on detecting noninferiority (NI) of ORR 24W and superiority of the primary safety endpoint. Two interim analyses (IA) will be performed when 150 and 200 pts have completed 24 wks of follow-up or discontinue earlier. Each analysis will test NI and futility of the LEN 14-mg arm ORR 24W vs the 18-mg arm ORR 24W . An O’Brien-Fleming boundary will be used for NI. If the 1-sided P-value is ≤ 0.005 at the first IA, ≤ 0.014 at the second IA, or ≤ 0.045 at the final analysis, then NI in ORR 24W will be claimed. If the futility boundary is crossed (ie, 1-sided P-value is ≥ 0.776 at the first IA or ≥ 0.207 at the second IA), then futility will be claimed. Clinical trial information: NCT03173560.

    Abstract: TPS4595 Background: Lenvatinib (LEN) is a multikinase inhibitor of vascular endothelial growth factor (VEGF) receptor 1–3, fibroblast growth factor receptor 1–4, platelet-derived growth factor receptor alpha, and RET and KIT. Based on a phase 2 study (Motzer et al. Lancet Oncol 2015), LEN was approved in combination with everolimus (EVE) for treatment of metastatic RCC following 1 prior VEGF-targeted therapy. A phase 1b/2 study of LEN in combination with pembrolizumab (PEM) in pts with RCC LEN is also underway. We report the design of a multicenter, open-label, phase 3 trial of LEN plus EVE or PEM vs sunitinib (SUN; a standard therapy for RCC) as first-line treatment for advanced RCC. Methods: Pts aged ≥ 18 years with confirmed advanced RCC diagnosis, ≥ 1 measurable lesion per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1, Karnofsky Performance Status ≥ 70, controlled blood pressure, and adequate blood coagulation, renal, hepatic, and bone marrow function are eligible. Pts will be randomized 1:1:1 to receive LEN 18 mg/day + EVE 5 mg/day, LEN 20 mg/day + PEM 200 mg every 3 weeks, or SUN 50 mg/day (on a schedule of 4 weeks on treatment followed by 2 weeks off) until disease progression, unacceptable toxicity, withdrawal of consent, or study end. The primary endpoint is to show superiority of LEN+EVE or LEN+PEM over single-agent SUN as first-line treatment for advanced RCC in improving progression-free survival (PFS). Secondary endpoints include comparison of objective response rate, overall survival, PFS on next-line therapy, health-related quality of life, and safety and tolerability in pts receiving LEN+EVE or LEN+PEM vs SUN. Exploratory endpoints include PFS in the LEN+PEM arm using immune-related RECIST, comparison of duration of response, disease control rate, and clinical benefit rate in pts treated with LEN+EVE or LEN+PEM vs SUN, and analysis of the relationship between blood biomarkers and outcome. No interim analysis is planned for efficacy or futility. Enrollment of 735 pts is planned to achieve 90% power at 2-sided α = 0.05 to detect a difference in ≥ 1 of the primary comparisons. Clinical trial information: NCT02811861.

    Abstract: 11 Background: Pembrolizumab (PEM), an anti-PD-1 antibody, is approved for advanced urothelial cancer in the second-line setting (objective response rate [ORR] 21%) and in the first-line setting for patients (pts) ineligible for cisplatin with combined positive score ≥10 or ineligible for platinum-based chemotherapy (ORR 29%). Tyrosine kinase inhibitors such as lenvatinib (LEN; a multikinase inhibitor of VEGFR 1-3, FGFR 1-3, PDGFRα, RET and KIT) have demonstrated activity in urothelial cancer and may reverse the immunosuppressive environment that leads to immuno-oncology (IO) failure. We present a phase 1b/2 trial of LEN + PEM in advanced urothelial cancer. Methods: In this multicenter, open-label study, pts with confirmed metastatic urothelial cancer and ECOG PS of 0 or 1 received oral LEN 20 mg/day + PEM (200 mg Q3W, IV). Pts were not preselected for PD-L1 status. The phase 2 primary end point was investigator-assessed ORR at week 24 (ORR wk24 ) per immune-related RECIST (irRECIST). Secondary end points included ORR, duration of response (DOR), and progression-free survival (PFS). Results: At data cutoff (March 1, 2018), 20 pts were enrolled: 9 (45%) PD-L1(+), 5 (25%) PD-L1(-); 6 (30%) not tested. 4 Pts (20%) were treatment-naïve; 11 (55%) and 5 (25%) pts had had 1 and 2 lines of prior anticancer therapies, respectively. No pt had received prior IO. ORR wk24 was 25% (95% CI: 8.7–49.1). 18 (90%) pts had ≥1 treatment-related adverse event (TRAE). Grade 3 and 4 TRAEs occurred in 5 (25%) and 5 (25%) pts, respectively. There was 1 fatal TRAE (gastrointestinal hemorrhage). The most common any-grade TRAEs were proteinuria (45%), diarrhea (40%), fatigue (30%), hypertension (30%), and hypothyroidism (30%). Conclusions: LEN + PEM demonstrated activity in this study of pts with advanced urothelial cancer, which included pts receiving later-line treatment, and deserves further investigation. Clinical trial information: NCT02501096. [Table: see text]

    Abstract: Modulation of vascular endothelial growth factor–mediated immune suppression via angiogenesis inhibition may augment the activity of immune checkpoint inhibitors. We report results from the dose-finding and initial phase II expansion of a phase Ib/II study of lenvatinib plus pembrolizumab in patients with selected advanced solid tumors. METHODS Eligible patients had metastatic renal cell carcinoma (RCC), endometrial cancer, squamous cell carcinoma of the head and neck (SCCHN), melanoma, non–small-cell lung cancer (NSCLC), or urothelial cancer. The primary objective of phase Ib was to determine the maximum tolerated dose (MTD) for lenvatinib plus pembrolizumab (200 mg intravenously every 3 weeks). In the preplanned phase II cohort expansion, the primary objective was objective response rate at week 24 (ORR week 24 ) at the recommended phase II dose. RESULTS Overall, 137 patients were enrolled during phase Ib (n = 13) and the initial phase II expansion (n = 124). Two dose-limiting toxicities (DLTs; grade 3 arthralgia and grade 3 fatigue) were reported in the initial dose level (lenvatinib 24 mg/d plus pembrolizumab). No DLTs were observed in the subsequent dose–de-escalation cohort, establishing the MTD and recommended phase II dose at lenvatinib 20 mg/d plus pembrolizumab. ORR week24 was as follows: RCC, 63% (19/30; 95% CI, 43.9% to 80.1%); endometrial cancer, 52% (12/23; 95% CI, 30.6% to 73.2%); melanoma, 48% (10/21; 95% CI, 25.7% to 70.2%); SCCHN, 36% (8/22; 95% CI, 17.2% to 59.3%); NSCLC, 33% (7/21; 95% CI, 14.6% to 57.0%); and urothelial cancer 25% (5/20; 95% CI, 8.7% to 49.1%). The most common treatment-related adverse events were fatigue (58%), diarrhea (52%), hypertension (47%), and hypothyroidism (42%). CONCLUSION Lenvatinib plus pembrolizumab demonstrated a manageable safety profile and promising antitumor activity in patients with selected solid tumor types.
