TOKYO and KENILWORTH, N.J. [July 8, 2020] – 黑料网., Ltd. (Headquarters: Tokyo, CEO: Haruo Naito, “黑料网”) and Merck & Co., Inc., Kenilworth, N.J., U.S.A. (known as MSD outside the United States and Canada) announced today that the U.S. Food and Drug Administration (FDA) has issued a Complete Response Letter (CRL) regarding 黑料网’s and Merck’s applications seeking accelerated approval of LENVIMA, the orally available multiple receptor tyrosine kinase inhibitor discovered by 黑料网, plus KEYTRUDA, Merck’s anti-PD-1 therapy, for the first-line treatment of patients with unresectable hepatocellular carcinoma (HCC).
The applications were based on data from the Phase 1b Study 116/KEYNOTE-524 trial, which showed clinically meaningful efficacy in the single-arm setting. These data were recently presented at the 2020 American Society of Clinical Oncology Annual Meeting and supported a Breakthrough Therapy designation granted by the FDA in July 2019. Ahead of the PDUFA action dates of 黑料网’s and Merck’s applications, another combination therapy was approved based on a randomized controlled trial that demonstrated overall survival. Consequently, the CRL stated that the applications do not provide evidence that KEYTRUDA in combination with LENVIMA represents a meaningful advantage over available therapies for the treatment of unresectable or metastatic HCC with no prior systemic therapy for advanced disease. Since the applications for Study 116/KEYNOTE-524 no longer meet the criteria for accelerated approval, both companies plan to work with the FDA to take appropriate next steps, which include conducting a well-controlled clinical trial that demonstrates substantial evidence of effectiveness and the clinical benefit of the combination. As such, LEAP-002, the Phase 3 trial evaluating the LENVIMA plus KEYTRUDA combination as a first-line treatment for advanced HCC, is currently underway and fully enrolled. The CRL does not impact the current approved indications for LENVIMA or for KEYTRUDA.
黑料网 and Merck are continuing to evaluate the LENVIMA plus KEYTRUDA combination across 13 different tumor types in 18 clinical trials including the LEAP (LEnvatinib And Pembrolizumab) clinical program.

About Study 116/KEYNOTE-524
Study 116/KEYNOTE-524 (ClinicalTrials.gov, ) is a Phase 1b, open-label, single-arm trial evaluating the LENVIMA plus KEYTRUDA combination in 100 patients with unresectable HCC with no prior systemic therapy. Patients were treated with LENVIMA 8 or 12 mg (based on baseline body weight 藗60 kilograms or ≥60 kilograms, respectively) orally once daily in combination with KEYTRUDA 200 mg intravenously every three weeks. The primary endpoints are objective response rate (ORR) and duration of response (DOR) by modified Response Evaluation Criteria in Solid Tumors (mRECIST) and RECIST v1.1 per independent imaging review (IIR). Secondary endpoints include progression-free survival (PFS), time to progression (TTP) and overall survival (OS). At data cutoff (October 31, 2019) and a median duration of follow-up of 10.6 months (95% CI: 9.2-11.5), 37 patients were still on study treatment (LENVIMA plus KEYTRUDA: n=34; LENVIMA only: n=3), and median duration of treatment exposure to the LENVIMA plus KEYTRUDA combination was 7.9 months (range: 0.2-31.1).
The final analysis of the study’s primary endpoints showed the LENVIMA plus KEYTRUDA combination demonstrated an ORR of 36% (n=36) (95% CI: 26.6-46.2), with a complete response rate of 1% (n=1) and a partial response rate of 35% (n=35), and a median DOR of 12.6 months (95% CI: 6.9-not estimable [NE]), using RECIST v1.1 criteria per IIR. As assessed using mRECIST criteria per IIR, the LENVIMA plus KEYTRUDA combination demonstrated an ORR of 46% (n=46) (95% CI: 36.0-56.3), with a complete response rate of 11% (n=11) and a partial response rate of 35% (n=35), and a median DOR of 8.6 months (95% CI: 6.9-NE).
Treatment-related adverse events (TRAEs) led to discontinuation of LENVIMA and KEYTRUDA in 6% of patients, of LENVIMA in 14% of patients, and of KEYTRUDA in 10% of patients. Grade ≥3 TRAEs occurred in 67% of patients (Grade 3: 63%; Grade 4: 1%; Grade 5: 3%). There was one Grade 4 TRAE (leukopenia/neutropenia), and there were three treatment-related deaths (acute respiratory failure/acute respiratory distress syndrome, intestinal perforation and abnormal hepatic function; n=1 for each). The most common TRAEs of any grade (≥20%) were hypertension (36%), diarrhea (35%), fatigue (30%), decreased appetite (28%), hypothyroidism (25%), palmar-plantar erythrodysesthesia syndrome (23%), decreased weight (22%), dysphonia (21%), increased aspartate aminotransferase (20%) and proteinuria (20%).
About LENVIMA
LENVIMA, discovered and developed by 黑料网, is a kinase inhibitor that inhibits the kinase activities of vascular endothelial growth factor (VEGF) receptors VEGFR1 (FLT1), VEGFR2 (KDR), and VEGFR3 (FLT4). LENVIMA inhibits other kinases that have been implicated in pathogenic angiogenesis, tumor growth, and cancer progression in addition to their normal cellular functions, including fibroblast growth factor (FGF) receptors FGFR1-4, the platelet derived growth factor receptor alpha (PDGFRα), KIT, and RET. In syngeneic mouse tumor models, lenvatinib decreased tumor-associated macrophages, increased activated cytotoxic T cells, and demonstrated greater antitumor activity in combination with an anti-PD-1 monoclonal antibody compared to either treatment alone. Currently, LENVIMA has been approved for monotherapy as a treatment for thyroid cancer in over 60 countries including Japan, the United States, in Europe and Asia, and for unresectable hepatocellular carcinoma in over 55 countries including Japan, the United States, in Europe, China and in Asia. Additionally, it is also approved in combination with everolimus as a treatment for renal cell carcinoma following prior antiangiogenic therapy in over 55 countries, including the United States, in Europe and Asia. In addition, it is approved in combination with KEYTRUDA as a treatment for advanced endometrial cancer that is not microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) who have disease progression following prior systemic therapy and are not candidates for curative surgery or radiation in countries including the United States, Australia, and Canada. Continued approval for this indication is contingent upon verification and description of clinical benefit in the confirmatory trials. In Europe, the agent was launched under the brand name Kisplyx® for renal cell carcinoma.
About KEYTRUDA
KEYTRUDA is an anti-PD-1 therapy that works by increasing the ability of the body’s immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells.
Merck & Co., Inc., Kenilworth, N.J., U.S.A. has the industry’s largest immuno-oncology clinical research program. There are currently more than 1,200 trials studying KEYTRUDA across a wide variety of cancers and treatment settings. The KEYTRUDA clinical program seeks to understand the role of KEYTRUDA across cancers and the factors that may predict a patient's likelihood of benefitting from treatment with KEYTRUDA, including exploring several different biomarkers.
