KEYNOTE-564 is the first Phase 3 trial to demonstrate superior overall survival (OS) with adjuvant therapy compared to placebo in patients with RCC
Late-breaking OS results selected for the official Press Program at the 2024 American Society of Clinical Oncology Genitourinary Cancers Symposium
RAHWAY, NJ, USA I January 27, 2024 I Merck (NYSE: MRK), known as MSD outside of the United States and Canada, today announced results from the Phase 3 KEYNOTE-564 trial evaluating KEYTRUDA, Merck’s anti-PD-1 therapy, for the adjuvant treatment of patients with renal cell carcinoma (RCC) at intermediate-high or high risk of recurrence following nephrectomy, or following nephrectomy and resection of metastatic lesions. These late-breaking data are being presented during an oral session for the first time today at the 2024 American Society of Clinical Oncology (ASCO) Genitourinary (GU) Cancers Symposium (abstract #LBA359) and are included in the official ASCO GU Press Program.
At the third pre-specified interim analysis (median follow-up of 57.2 months [range, 47.9−74.5 months]), KEYTRUDA as adjuvant therapy significantly improved overall survival (OS), the trial’s key secondary endpoint, by 38% (HR=0.62 [95% CI, 0.44−0.87]; p=0.002) compared to placebo. At 48 months, the estimated OS rate was 91.2% for patients who received KEYTRUDA compared to 86.0% for patients who received placebo. The OS benefit for patients who received KEYTRUDA was observed across key subgroups.
“For patients with renal cell carcinoma, up to 40% may experience recurrence following surgery, at which point there is a significantly lower chance of survival,” said Dr. Toni K. Choueiri, director, Lank Center for Genitourinary Oncology, Dana-Farber Cancer Institute and Jerome and Nancy Kohlberg professor of medicine, Harvard Medical School. “Results from KEYNOTE-564 show that pembrolizumab as adjuvant therapy significantly improved overall survival by 38% compared to placebo, becoming the first ever Phase 3 adjuvant trial to show improved survival for renal cancer patients at risk of recurrence after surgery.”
“The positive overall survival results from KEYNOTE-564 build upon the disease-free survival data, which supported approvals of KEYTRUDA for this indication worldwide,” said Dr. Marjorie Green, senior vice president and head of oncology, global clinical development, Merck Research Laboratories. “This is the second KEYTRUDA study to demonstrate a significant overall survival benefit in an earlier stage of cancer, and these new results add to the progress we’re making in earlier stages of disease.”
As previously reported, at an earlier pre-specified interim analysis with a median follow-up of 24.1 months, KEYNOTE-564 met its primary endpoint of disease-free survival (DFS), reducing the risk of disease recurrence or death by 32% (HR=0.68 [95% CI, 0.53-0.87]; one-sided p=0.001) compared to placebo. At this third interim analysis, the DFS benefit was consistent with these previously reported data, with KEYTRUDA as adjuvant therapy reducing the risk of disease recurrence or death by 28% (HR=0.72 [95% CI, 0.59-0.87]) compared to placebo.
KEYTRUDA is approved for the adjuvant treatment of patients with RCC in the U.S., European Union, Japan and other countries worldwide based on DFS data from KEYNOTE-564, which were first presented at the 2021 ASCO Annual Meeting. Merck is currently working with health authorities to include these OS data in the full KEYTRUDA prescribing information.
Merck has a broad clinical development program in RCC across multiple settings, including adjuvant and advanced disease, utilizing KEYTRUDA as monotherapy or in combination with WELIREG (belzutifan, Merck’s oral hypoxia-inducible factor-2 alpha [HIF-2α] inhibitor), LENVIMA (lenvatinib, a multi-targeted VEGF TKI, in collaboration with Eisai) and quavonlimab (a CTLA-4 monoclonal antibody being developed under an agreement with Akeso Inc.).
Study design and additional data from KEYNOTE-564
KEYNOTE-564 is a randomized, double-blind Phase 3 trial (ClinicalTrials.gov, NCT03142334) evaluating KEYTRUDA for the adjuvant treatment of patients with RCC who have undergone nephrectomy and who have disease that is intermediate-high risk, high risk or M1 no evidence of disease (NED). The primary endpoint is DFS as assessed by investigator review, and secondary endpoints include OS and safety. The study enrolled 994 patients who were randomized 1:1 to receive either KEYTRUDA (200 mg intravenously [IV] on Day 1 of each three-week cycle for up to 17 cycles) or placebo (saline solution IV on Day 1 of each three-week cycle for up to 17 cycles).
The OS benefit for patients who received KEYTRUDA was observed across key subgroups, including in patients with M0 disease (HR=0.63 [95% CI, 0.44-0.90]), M1 NED (HR=0.51 [95% CI, 0.15-1.75]), PD-L1 Combined Positive Score (CPS) <1 (HR=0.65 [95% CI, 0.31−1.38]) or CPS ≥1 (HR=0.62 [95% CI, 0.42−0.91]), and in patients with presence (HR=0.69 [95% CI, 0.28−1.70]) or absence (HR=0.57 [95% CI 0.39−0.84]) of sarcomatoid features.
The safety profile of KEYTRUDA was consistent with that observed in previously reported studies; no new safety signals were observed. Treatment-related adverse events (TRAEs) occurred in 79.1% of patients (n=386) in the KEYTRUDA arm and 53.0% of patients (n=263) in the placebo arm. Grade 3-4 TRAEs occurred in 18.6% of patients in the KEYTRUDA arm and 1.2% of patients in the placebo arm. Treatment-related adverse events resulting in discontinuation of any treatment occurred in 18.2% of patients in the KEYTRUDA arm and 0.8% of patients in the placebo arm. No treatment-related deaths occurred.
About renal cell carcinoma
Renal cell carcinoma is by far the most common type of kidney cancer; about nine out of 10 kidney cancer diagnoses are RCCs. Renal cell carcinoma is about twice as common in men than in women. Most cases of RCC are discovered incidentally during imaging tests for other abdominal diseases. Renal cell carcinoma is associated with a high risk of recurrence, with up to 40% of newly diagnosed patients experiencing recurrence within five years following surgery. In the U.S., it is estimated there will be approximately 81,600 new cases of kidney cancer diagnosed and approximately 14,400 deaths from the disease in 2024. Worldwide, it is estimated there were approximately 431,000 new cases of kidney cancer diagnosed and more than 179,000 deaths from the disease in 2020.
About Merck’s early-stage cancer clinical program
Finding cancer at an earlier stage may give patients a greater chance of long-term survival. Many cancers are considered most treatable and potentially curable in their earliest stage of disease. Building on the strong understanding of the role of KEYTRUDA in later-stage cancers, Merck is studying KEYTRUDA in earlier disease states, with more than 25 ongoing registrational studies across multiple types of cancer.
About KEYTRUDA® (pembrolizumab) injection, 100 mg
KEYTRUDA is an anti-programmed death receptor-1 (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 1,600 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.

KEYNOTE-564 is the first Phase 3 trial to demonstrate superior overall survival (OS) with adjuvant therapy compared to placebo in patients with RCC
Late-breaking OS results selected for the official Press Program at the 2024 American Society of Clinical Oncology Genitourinary Cancers Symposium
RAHWAY, NJ, USA I January 27, 2024 I Merck (NYSE: MRK), known as MSD outside of the United States and Canada, today announced results from the Phase 3 KEYNOTE-564 trial evaluating KEYTRUDA, Merck’s anti-PD-1 therapy, for the adjuvant treatment of patients with renal cell carcinoma (RCC) at intermediate-high or high risk of recurrence following nephrectomy, or following nephrectomy and resection of metastatic lesions.

Tumor Mutational Burden-High Cancer
KEYTRUDA is indicated for the treatment of adult and pediatric patients with unresectable or metastatic tumor mutational burden-high (TMB-H) [≥10 mutations/megabase (mut/Mb)] solid tumors, as determined by an FDA-approved test, that have progressed following prior treatment and who have no satisfactory alternative treatment options. This indication is approved under accelerated approval based on tumor response rate and durability of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in the confirmatory trials. The safety and effectiveness of KEYTRUDA in pediatric patients with TMB-H central nervous system cancers have not been established.

About LENVIMA® (lenvatinib); available as 10 mg and 4 mg capsules
LENVIMA, discovered and developed by Eisai, is an orally available multiple receptor tyrosine 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, LENVIMA 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.
LENVIMA® (lenvatinib) Indications in the U.S.
- For the treatment of patients with locally recurrent or metastatic, progressive, radioactive iodine-refractory differentiated thyroid cancer (DTC)
- In combination with pembrolizumab, for the first-line treatment of adult patients with advanced renal cell carcinoma (RCC)
- In combination with everolimus, for the treatment of adult patients with advanced renal cell carcinoma (RCC) following one prior anti-angiogenic therapy
- For the first-line treatment of patients with unresectable hepatocellular carcinoma (HCC)
- In combination with pembrolizumab, for the treatment of patients with advanced endometrial carcinoma (EC) that is mismatch repair proficient (pMMR), as determined by an FDA-approved test, or not microsatellite instability-high (MSI-H), who have disease progression following prior systemic therapy in any setting and are not candidates for curative surgery or radiation.
