KENILWORTH, N.J. & WOODCLIFF LAKE, N.J.--(BUSINESS WIRE)-- Merck (NYSE: MRK), known as MSD outside the United States and Canada, and Eisai today announced the first presentation of new investigational data from the pivotal Phase 3 CLEAR study (KEYNOTE-581/Study 307) 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 Medicine. The trial evaluated the combinations of KEYTRUDA, Merck?s anti-PD-1 therapy, plus LENVIMA, the orally available multiple receptor tyrosine kinase inhibitor discovered by Eisai, and LENVIMA plus everolimus versus sunitinib for the first-line treatment of patients with advanced renal cell carcinoma (RCC). KEYTRUDA plus LENVIMA 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 today. The safety profiles of both KEYTRUDA plus LENVIMA 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, KEYTRUDA plus LENVIMA 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, KEYTRUDA plus LENVIMA 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 KEYTRUDA plus LENVIMA 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 KEYTRUDA plus LENVIMA 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 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 (KEYNOTE-581/Study 307) represent a significant milestone in our clinical research efforts in advanced renal cell carcinoma, with encouraging Phase 3 results in this population for the KEYTRUDA plus LENVIMA 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 KEYTRUDA plus LENVIMA arm, treatment-related adverse events (TRAEs) led to discontinuation of KEYTRUDA in 25.0% of patients, of LENVIMA in 18.5% 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 10.0% of patients. Grade 5 TRAEs occurred in 1.1% of patients in the KEYTRUDA plus LENVIMA arm, in 0.8% of patients in the LENVIMA plus everolimus arm, and in 0.3% of patients in the sunitinib arm. Grade =3 TRAEs occurred in 71.6% of patients in the KEYTRUDA plus LENVIMA 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 KEYTRUDA plus LENVIMA 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%). CLEAR Study (KEYNOTE-581/Study 307) Trial Design (Abstract #269) The CLEAR study (KEYNOTE-581/Study 307) is a Phase 3, multicenter, randomized, open-label trial (ClinicalTrials.gov, NCT02811861) 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).
About 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. 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. Renal cell carcinoma is by far the most common type of kidney cancer; about nine out of 10 kidney cancers are RCCs. Renal cell carcinoma is about twice as common in men as in women. 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. 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. About KEYTRUDA??(pembrolizumab) Injection, 100 mg 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 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.

Selected Important Safety Information for KEYTRUDA Severe and Fatal Immune-Mediated Adverse Reactions KEYTRUDA is a monoclonal antibody that belongs to a class of drugs that bind to either the programmed death receptor-1 (PD-1) or the programmed death ligand 1 (PD-L1), blocking the PD-1/PD-L1 pathway, thereby removing inhibition of the immune response, potentially breaking peripheral tolerance and inducing immune-mediated adverse reactions. Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue, can affect more than one body system simultaneously, and can occur at any time after starting treatment or after discontinuation of treatment. Important immune-mediated adverse reactions listed here may not include all possible severe and fatal immune-mediated adverse reactions. Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Early identification and management are essential to ensure safe use of anti?PD-1/PD-L1 treatments. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate. Withhold or permanently discontinue KEYTRUDA depending on severity of the immune-mediated adverse reaction. In general, if KEYTRUDA requires interruption or discontinuation, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose adverse reactions are not controlled with corticosteroid therapy. Immune-Mediated Pneumonitis KEYTRUDA can cause immune-mediated pneumonitis. The incidence is higher in patients who have received prior thoracic radiation. Immune-mediated pneumonitis occurred in 3.4% (94/2799) of patients receiving KEYTRUDA, including fatal (0.1%), Grade 4 (0.3%), Grade 3 (0.9%), and Grade 2 (1.3%) reactions. Systemic corticosteroids were required in 67% (63/94) of patients. Pneumonitis led to permanent discontinuation of KEYTRUDA in 1.3% (36) and withholding in 0.9% (26) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 23% had recurrence. Pneumonitis resolved in 59% of the 94 patients. Pneumonitis occurred in 8% (31/389) of adult patients with cHL receiving KEYTRUDA as a single agent, including Grades 3-4 in 2.3% of patients. Patients received high-dose corticosteroids for a median duration of 10 days (range: 2 days to 53 months). Pneumonitis rates were similar in patients with and without prior thoracic radiation. Pneumonitis led to discontinuation of KEYTRUDA in 5.4% (21) of patients. Of the patients who developed pneumonitis, 42% of these patients interrupted KEYTRUDA, 68% discontinued KEYTRUDA, and 77% had resolution. Immune-Mediated Colitis KEYTRUDA can cause immune-mediated colitis, which may present with diarrhea. Cytomegalovirus infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. Immune-mediated colitis occurred in 1.7% (48/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (1.1%), and Grade 2 (0.4%) reactions. Systemic corticosteroids were required in 69% (33/48); additional immunosuppressant therapy was required in 4.2% of patients. Colitis led to permanent discontinuation of KEYTRUDA in 0.5% (15) and withholding in 0.5% (13) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 23% had recurrence. Colitis resolved in 85% of the 48 patients. Hepatotoxicity and Immune-Mediated Hepatitis KEYTRUDA?as a Single Agent KEYTRUDA can cause immune-mediated hepatitis. Immune-mediated hepatitis occurred in 0.7% (19/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (0.4%), and Grade 2 (0.1%) reactions. Systemic corticosteroids were required in 68% (13/19) of patients; additional immunosuppressant therapy was required in 11% of patients. Hepatitis led to permanent discontinuation of KEYTRUDA in 0.2% (6) and withholding in 0.3% (9) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, none had recurrence. Hepatitis resolved in 79% of the 19 patients. KEYTRUDA with Axitinib KEYTRUDA in combination with axitinib can cause hepatic toxicity. Monitor liver enzymes before initiation of and periodically throughout treatment. Consider monitoring more frequently as compared to when the drugs are administered as single agents. For elevated liver enzymes, interrupt KEYTRUDA and axitinib, and consider administering corticosteroids as needed. With the combination of KEYTRUDA and axitinib, Grades 3 and 4 increased alanine aminotransferase (ALT) (20%) and increased aspartate aminotransferase (AST) (13%) were seen, which was at a higher frequency compared to KEYTRUDA alone. Fifty-nine percent of the patients with increased ALT received systemic corticosteroids. In patients with ALT =3 times upper limit of normal (ULN) (Grades 2-4, n=116), ALT resolved to Grades 0-1 in 94%. Among the 92 patients who were rechallenged with either KEYTRUDA (n=3) or axitinib (n=34) administered as a single agent or with both (n=55), recurrence of ALT =3 times ULN was observed in 1 patient receiving KEYTRUDA, 16 patients receiving axitinib, and 24 patients receiving both. All patients with a recurrence of ALT =3 ULN subsequently recovered from the event. Immune-Mediated Endocrinopathies Adrenal Insufficiency KEYTRUDA can cause primary or secondary adrenal insufficiency. For Grade 2 or higher, initiate symptomatic treatment, including hormone replacement as clinically indicated. Withhold KEYTRUDA depending on severity. Adrenal insufficiency occurred in 0.8% (22/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (0.3%), and Grade 2 (0.3%) reactions. Systemic corticosteroids were required in 77% (17/22) of patients; of these, the majority remained on systemic corticosteroids. Adrenal insufficiency led to permanent discontinuation of KEYTRUDA in <0.1% (1) and withholding in 0.3% (8) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement. Hypophysitis KEYTRUDA can cause immune-mediated hypophysitis. Hypophysitis can present with acute symptoms associated with mass effect such as headache, photophobia, or visual field defects. Hypophysitis can cause hypopituitarism. Initiate hormone replacement as indicated. Withhold or permanently discontinue KEYTRUDA depending on severity. Hypophysitis occurred in 0.6% (17/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (0.3%), and Grade 2 (0.2%) reactions. Systemic corticosteroids were required in 94% (16/17) of patients; of these, the majority remained on systemic corticosteroids. Hypophysitis led to permanent discontinuation of KEYTRUDA in 0.1% (4) and withholding in 0.3% (7) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement. Thyroid Disorders KEYTRUDA can cause immune-mediated thyroid disorders. Thyroiditis can present with or without endocrinopathy. Hypothyroidism can follow hyperthyroidism.

Thyroiditis occurred in 0.6% (16/2799) of patients receiving KEYTRUDA, including Grade 2 (0.3%). None discontinued, but KEYTRUDA was withheld in <0.1% (1) of patients. Hyperthyroidism occurred in 3.4% (96/2799) of patients receiving KEYTRUDA, including Grade 3 (0.1%) and Grade 2 (0.8%). It led to permanent discontinuation of KEYTRUDA in <0.1% (2) and withholding in 0.3% (7) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement. Hypothyroidism occurred in 8% (237/2799) of patients receiving KEYTRUDA, including Grade 3 (0.1%) and Grade 2 (6.2%). It led to permanent discontinuation of KEYTRUDA in <0.1% (1) and withholding in 0.5% (14) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement. The majority of patients with hypothyroidism required long-term thyroid hormone replacement. The incidence of new or worsening hypothyroidism was higher in 1185 patients with HNSCC, occurring in 16% of patients receiving KEYTRUDA as a single agent or in combination with platinum and FU, including Grade 3 (0.3%) hypothyroidism. The incidence of new or worsening hypothyroidism was higher in 389 adult patients with cHL (17%) receiving KEYTRUDA as a single agent, including Grade 1 (6.2%) and Grade 2 (10.8%) hypothyroidism. Type 1 Diabetes Mellitus (DM), Which Can Present With Diabetic Ketoacidosis Monitor patients for hyperglycemia or other signs and symptoms of diabetes. Initiate treatment with insulin as clinically indicated. Withhold KEYTRUDA depending on severity. Type 1 DM occurred in 0.2% (6/2799) of patients receiving KEYTRUDA.

All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, none had recurrence. Nephritis resolved in 56% of the 9 patients. Immune-Mediated Dermatologic Adverse Reactions KEYTRUDA can cause immune-mediated rash or dermatitis. Exfoliative dermatitis, including Stevens-Johnson syndrome, drug rash with eosinophilia and systemic symptoms, and toxic epidermal necrolysis, has occurred with anti?PD-1/PD-L1 treatments. Topical emollients and/or topical corticosteroids may be adequate to treat mild to moderate nonexfoliative rashes. Withhold or permanently discontinue KEYTRUDA depending on severity. Immune-mediated dermatologic adverse reactions occurred in 1.4% (38/2799) of patients receiving KEYTRUDA, including Grade 3 (1%) and Grade 2 (0.1%) reactions. Systemic corticosteroids were required in 40% (15/38) of patients. These reactions led to permanent discontinuation in 0.1% (2) and withholding of KEYTRUDA in 0.6% (16) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 6% had recurrence. The reactions resolved in 79% of the 38 patients. Other Immune-Mediated Adverse Reactions The following clinically significant immune-mediated adverse reactions occurred at an incidence of <1% (unless otherwi
