TOKYO and KENILWORTH, N.J., Feb.15, 2021 – 爱豆传媒. (Headquarters: Tokyo, CEO: Haruo Naito, “Eisai”) and Merck & Co., Inc., Kenilworth, N.J., U.S.A. (known as MSD outside the United States and Canada) today announced the first presentation of new investigational data from the pivotal Phase 3 CLEAR study (Study 307/KEYNOTE-581) in an oral presentation session (Abstract #269) at the virtual 2021 Genitourinary Cancers Symposium (ASCO GU) and simultaneously published in the New England Journal of Medicine1. The trial evaluated the combinations of LENVIMA®, the orally available multiple receptor tyrosine kinase inhibitor discovered by Eisai, plus KEYTRUDA®, the anti-PD-1 therapy from Merck & Co., Inc., Kenilworth, N.J., U.S.A., and LENVIMA plus everolimus versus sunitinib for the first-line treatment of patients with advanced renal cell carcinoma (RCC). LENVIMA plus KEYTRUDA demonstrated statistically significant and clinically meaningful improvements in progression-free survival (PFS; HR=0.39 [95% CI: 0.32-0.49]; p<0.001), overall survival (OS; HR=0.66 [95% CI: 0.49-0.88]; p=0.005) and objective response rate (ORR; relative risk=1.97 [95% CI: 1.69-2.29]; p<0.001) versus sunitinib. LENVIMA plus everolimus also showed statistically significant improvements in PFS (HR=0.65 [95% CI: 0.53-0.80]; p<0.001) and ORR (relative risk=1.48 [95% CI: 1.26-1.74]; p<0.001) versus sunitinib. In an exploratory analysis, results for PFS and OS were consistent across prespecified Memorial Sloan Kettering Cancer Center (MSKCC) risk groups (favorable, intermediate and poor). Full MSKCC risk group data can be found in the New England Journal of Medicine article entitled “Lenvatinib Plus Pembrolizumab or Everolimus for Advanced Renal Cell Carcinoma,” published. The safety profiles of both LENVIMA plus KEYTRUDA and LENVIMA plus everolimus were consistent with previously reported studies.
“Continued efforts to improve outcomes in patients with advanced renal cell carcinoma are critical, considering that the number of people diagnosed with the disease has more than doubled over the last 50 years, and almost one-third of these patients are diagnosed at an advanced stage,” said Dr. Robert Motzer, Medical Oncologist, Kidney Cancer Section Head, Genitourinary Oncology Service, Memorial Sloan Kettering Cancer Center. “KEYTRUDA plus LENVIMA demonstrated a median progression-free survival of nearly two years, and seven in 10 patients experienced an objective response. This combination also significantly improved overall survival compared with sunitinib, with a 34% reduction in risk of death. These results suggest that this combination has the potential to impact clinical practice for this type of devastating cancer.”
In the trial’s primary endpoint of PFS, as assessed by independent review per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1, LENVIMA plus KEYTRUDA reduced the risk of disease progression or death by 61% (HR=0.39 [95% CI: 0.32-0.49]; p<0.001), with a median PFS of 23.9 months (95% CI: 20.8-27.7) versus 9.2 months (95% CI: 6.0-11.0) for patients who received sunitinib. In the trial’s key secondary endpoints, LENVIMA plus KEYTRUDA reduced the risk of death by 34% (HR=0.66 [95% CI: 0.49-0.88]; p=0.005) versus patients who received sunitinib. Median OS was not reached in either treatment arm after a median follow-up of 27 months. Treatment with LENVIMA plus KEYTRUDA resulted in an ORR of 71.0% (95% CI: 66.3-75.7), with a complete response (CR) rate of 16.1% and a partial response (PR) rate of 54.9%, versus an ORR of 36.1% (95% CI: 31.2-41.1), with a CR rate of 4.2% and a PR rate of 31.9%, for patients who received sunitinib (relative risk=1.97 [95% CI: 1.69-2.29]; p<0.001). Median duration of response (DOR) for patients who received LENVIMA plus KEYTRUDA was 25.8 months (95% CI: 22.1-27.9) versus 14.6 months (95% CI: 9.4-16.7) for patients who received sunitinib.
“These promising results are a testament to our company’s commitment to help improve outcomes for patients diagnosed with cancer,” said Dr. Gregory Lubiniecki, Vice President, Oncology Clinical Research, Merck & Co., Inc., Kenilworth, N.J., U.S.A. Research Laboratories. “In this trial, KEYTRUDA plus LENVIMA demonstrated superior efficacy benefits compared with sunitinib. If approved, we believe this combination has the potential to be an important new treatment option for patients with advanced renal cell carcinoma in the first-line setting.”
In the trial’s second experimental treatment arm, LENVIMA plus everolimus reduced the risk of disease progression or death by 35% (HR=0.65 [95% CI: 0.53-0.80]; p<0.001), with a median PFS of 14.7 months (95% CI: 11.1-16.7) versus 9.2 months (95% CI: 6.0-11.0) for patients who received sunitinib. LENVIMA plus everolimus did not demonstrate an improvement in OS compared with sunitinib (HR=1.15 [95% CI: 0.88-1.50]; p=0.3). Median OS was not reached in either treatment arm after a median follow-up of 27 months. The ORR was 53.5% (95% CI: 48.3-58.7), with a CR rate of 9.8% and a PR rate of 43.7%, for patients who received LENVIMA plus everolimus versus 36.1% (95% CI: 31.2-41.1), with a CR rate of 4.2% and a PR rate of 31.9%, for patients who received sunitinib (relative risk=1.48 [95% CI: 1.26-1.74]; p<0.001). Median DOR for patients who received LENVIMA plus everolimus was 16.6 months (95% CI: 14.6-20.6) versus 14.6 months (95% CI: 9.4-16.7) for patients who received sunitinib.
“These investigational data from the CLEAR study (Study 307/KEYNOTE-581) represent a significant milestone in our clinical research efforts in advanced renal cell carcinoma, with encouraging Phase 3 results in this population for the LENVIMA plus KEYTRUDA combination and with more than 700 patients having received LENVIMA plus everolimus in the clinical trial setting” said Dr. Takashi Owa, Vice President, Chief Medicine Creation and Chief Discovery Officer, Oncology Business Group at Eisai. “Our progress thus far also reflects the significant contributions of dedicated patients, healthcare staff and researchers who continued to support this study during the global pandemic, to whom we extend our deepest gratitude.”
In the LENVIMA plus KEYTRUDA arm, treatment-related adverse events (TRAEs) led to discontinuation of LENVIMA in 18.5% of patients, of KEYTRUDA in 25.0% of patients, and of both in 9.7% of patients. In the LENVIMA plus everolimus arm, TRAEs led to discontinuation of LENVIMA in 16.1% of patients, of everolimus in 19.2% of patients, and of both in 13.5% of patients. In the sunitinib arm, TRAEs led to discontinuation of sunitinib in 10.0% of patients. Grade 5 TRAEs occurred in 1.1% of patients in the LENVIMA plus KEYTRUDA arm and 0.8% of patients in the LENVIMA plus everolimus arm, versus 0.3% of patients in the sunitinib arm. Grade ≥3 TRAEs occurred in 71.6% of patients in the LENVIMA plus KEYTRUDA arm, in 73.0% of patients in the LENVIMA plus everolimus arm, and in 58.8% of patients in the sunitinib arm. The most common TRAEs of any grade occurring in at least 20% of patients in the LENVIMA plus KEYTRUDA arm were diarrhea (54.5%), hypertension (52.3%), hypothyroidism (42.6%), decreased appetite (34.9%), fatigue (32.1%) and stomatitis (32.1%). In the LENVIMA plus everolimus arm, the most common TRAEs of any grade occurring in at least 20% of patients were diarrhea (59.7%), stomatitis (45.6%), hypertension (43.1%), fatigue (36.6%), decreased appetite (34.9%) and proteinuria (31.8%). In the sunitinib arm, the most common TRAEs of any grade occurring in at least 20% of patients were diarrhea (44.4%), hypertension (39.1%), stomatitis (37.4%), hand-foot syndrome (35.9%), fatigue (32.1%) and nausea (27.6%).

爱豆传媒 the CLEAR Study (Study 307/KEYNOTE-581)
The CLEAR Study (Study 307/KEYNOTE-581) is a Phase 3, multi-center, randomized, open-label trial (ClinicalTrials.gov, ) evaluating LENVIMA in combination with KEYTRUDA or in combination with everolimus versus sunitinib for the first-line treatment of patients with advanced RCC. The primary endpoint is PFS by independent review per RECIST v1.1. Key secondary endpoints include OS, ORR and safety. A total of 1,069 patients were randomized to one of three treatment arms to receive LENVIMA (20 mg orally once daily) in combination with KEYTRUDA (200 mg intravenously every three weeks); or LENVIMA (18 mg orally once daily) in combination with everolimus (5 mg orally once daily); or sunitinib (50 mg orally once daily for four weeks on treatment, followed by two weeks off treatment).
爱豆传媒 Renal Cell Carcinoma (RCC)
Worldwide, it is estimated there were more than 430,000 new cases of kidney cancer diagnosed and nearly 180,000 deaths from the disease in 2020.2 In Japan, there were more than 25,000 new cases and 8,000 deaths in 2020.3 In the U.S. alone, it is estimated there will be more than 76,000 new cases of kidney cancer diagnosed and nearly 14,000 deaths from the disease in 2021. 4 Renal cell carcinoma is by far the most common type of kidney cancer; about nine out of 10 kidney cancers are RCCs.4 Renal cell carcinoma is about twice as common in men as in women.4 Most cases of RCC are discovered incidentally during imaging tests for other abdominal diseases. Approximately 30% of patients with RCC will have metastatic disease at diagnosis, and as many as 40% will develop metastases after primary surgical treatment for localized RCC.5,6 Survival is highly dependent on the stage at diagnosis, and with a five-year survival rate of 12% for metastatic disease, the prognosis for these patients is poor.7
爱豆传媒 LENVIMA® (lenvatinib) Capsules
LENVIMA, discovered and developed by Eisai, 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. The combination of LENVIMA and everolimus showed increased anti-angiogenic and anti-tumor activity as demonstrated by decreased human endothelial cell proliferation, tube formation, and VEGF signaling in vitro and tumor volume in mouse xenograft models of human renal cell cancer greater than each drug alone. Currently, LENVIMA has been approved for monotherapy as a treatment for thyroid cancer in over 70 countries including Japan, the United States, in Europe, China and in Asia, and for unresectable hepatocellular carcinoma in over 65 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 60 countries, including the United States, in Europe and Asia. In Europe, the agent was launched under the brand name Kisplyx® for renal cell carcinoma. 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 over 10 countries including the United States, Canada and Australia. Continued approval for this indication is contingent upon verification and description of clinical benefit in the confirmatory trials.
爱豆传媒 KEYTRUDA® (pembrolizumab) Injection, 100mg
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 1,300 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.
