FDA Grants Priority Review to Merck?s Supplemental Biologics License Application for KEYTRUDA? (pembrolizumab) for the Treatment of Merkel Cell Carcinoma, a Rare Form of Skin Cancer
KENILWORTH, N.J., Merck (NYSE:MRK), known as MSD outside the United States and Canada, today announced that the U.S. Food and Drug Administration (FDA) has accepted and granted priority review for a new supplemental Biologics License Application (sBLA) seeking accelerated approval for KEYTRUDA, Merck?s anti-PD-1 therapy, for the treatment of adult and pediatric patients with recurrent locally advanced or metastatic Merkel cell carcinoma (MCC). This sBLA is based on data from the Phase 2 KEYNOTE-017 trial including overall response rate (ORR) and duration of response (DOR); these data were presented earlier this year at the 2018 American Society of Clinical Oncology (ASCO) Annual Meeting. In July 2017, KEYTRUDA was granted Breakthrough Therapy Designation by the FDA for this indication. The FDA has set a Prescription Drug User Fee Act (PDUFA), or target action, date of Dec. 28, 2018.
?Merkel cell carcinoma, a rare type of skin cancer, is an aggressive and fast-growing disease that has been associated with mortality rates higher than other types of skin cancer, including melanoma,? said Dr. Scot Ebbinghaus, vice president, clinical research, Merck Research Laboratories. ?KEYNOTE-017 represents the longest observation to date of patients with advanced Merkel cell carcinoma receiving anti-PD-1 therapy in the first-line setting, and demonstrated durable tumor control in these patients. We look forward to working closely with the FDA throughout the review process and to bringing KEYTRUDA to patients with Merkel cell carcinoma.?
Merck?s long-term commitment to skin cancers includes a broad clinical development program studying KEYTRUDA as monotherapy and in combination with other novel mechanisms. The program, which is comprised of over 4,500 patients across more than 10 Merck-sponsored clinical studies, is evaluating KEYTRUDA across most settings and stages, as well as different subtypes of the disease.
About Merkel Cell Carcinoma
Merkel cell carcinoma is an aggressive and rare form of skin cancer that is often caused by a Merkel cell associated polyomavirus. More than 90 percent of people diagnosed with MCC are older than 50 years of age. Merkel cell carcinoma is more likely to spread to other parts of the body than most types of skin cancer. It is estimated that about 2,500 cases of MCC are diagnosed each year in the United States, which has the highest incidence of the disease along with Australia and New Zealand. Historically, MCC has an 18-month survival rate of about 30 percent.
About 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 has the industry?s largest immuno-oncology clinical research program. There are currently more than 800 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.
KEYTRUDA???(pembrolizumab) Indications and Dosing
Melanoma
KEYTRUDA is indicated for the treatment of patients with unresectable or metastatic melanoma at a fixed dose of 200 mg every three weeks until disease progression or unacceptable toxicity.
Lung Cancer
KEYTRUDA, in combination with pemetrexed and platinum chemotherapy, is indicated for the first-line treatment of patients with metastatic nonsquamous NSCLC, with no EGFR or ALK genomic tumor aberrations.
KEYTRUDA, as a single agent, is indicated for the first-line treatment of patients with metastatic non-small cell lung cancer (NSCLC) whose tumors have high PD-L1 expression [Tumor Proportion Score (TPS) =50%] as determined by an FDA-approved test, with no EGFR or ALK?genomic tumor aberrations.
KEYTRUDA, as a single agent, is also indicated for the treatment of patients with metastatic NSCLC whose tumors express PD-L1 (TPS =1%) as determined by an FDA-approved test, with disease progression on or after platinum-containing chemotherapy. Patients with EGFR or ALK genomic tumor aberrations should have disease progression on FDA-approved therapy for these aberrations prior to receiving KEYTRUDA.
In metastatic NSCLC, KEYTRUDA is administered at a fixed dose of 200 mg every three weeks until disease progression, unacceptable toxicity, or up to 24 months in patients without disease progression.
When administering KEYTRUDA in combination with chemotherapy, KEYTRUDA should be administered prior to chemotherapy when given on the same day. See also the Prescribing Information for pemetrexed and carboplatin or cisplatin, as appropriate.
Head and Neck Cancer
KEYTRUDA is indicated for the treatment of patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) with disease progression on or after platinum-containing chemotherapy. 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. In HNSCC, KEYTRUDA is administered at a fixed dose of 200 mg every three weeks until disease progression, unacceptable toxicity, or up to 24 months in patients without disease progression.
Classical Hodgkin Lymphoma
KEYTRUDA is indicated for the treatment of adult and pediatric patients with refractory classical Hodgkin lymphoma (cHL), or who have relapsed after three or more prior lines of therapy. 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. In adults with cHL, KEYTRUDA is administered at a fixed dose of 200 mg every three weeks until disease progression or unacceptable toxicity, or up to 24 months in patients without disease progression. In pediatric patients with cHL, KEYTRUDA is administered at a dose of 2 mg/kg (up to a maximum of 200 mg) every three weeks until disease progression or unacceptable toxicity, or up to 24 months in patients without disease progression.
Primary Mediastinal Large B-Cell Lymphoma
KEYTRUDA is indicated for the treatment of adult and pediatric patients with refractory primary mediastinal large B-cell lymphoma (PMBCL), or who have relapsed after 2 or more prior lines of therapy. 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 confirmatory trials. KEYTRUDA is not recommended for the treatment of patients with PMBCL who require urgent cytoreductive therapy.
In adults with PMBCL, KEYTRUDA is administered at a fixed dose of 200 mg every three weeks until disease progression, unacceptable toxicity, or up to 24 months in patients without disease progression. In pediatric patients with PMBCL, KEYTRUDA is administered at a dose of 2 mg/kg (up to a maximum of 200 mg) every three weeks until disease progression or unacceptable toxicity, or up to 24 months in patients without disease progression.
Urothelial Carcinoma
KEYTRUDA is indicated for the treatment of patients with locally advanced or metastatic urothelial carcinoma (mUC) who are not eligible for cisplatin-containing chemotherapy and whose tumors express PD-L1 [Combined Positive Score (CPS) =10] as determined by an FDA-approved test, or in patients who are not eligible for any platinum-containing chemotherapy regardless of PD-L1 status. This indication is approved under accelerated approval based on tumor response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in the confirmatory trials.
KEYTRUDA is also indicated for the treatment of patients with locally advanced or metastatic urothelial carcinoma (mUC) who have disease progression during or following platinum-containing chemotherapy or within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy.
In locally advanced or metastatic urothelial carcinoma, KEYTRUDA is administered at a fixed dose of 200 mg every three weeks until disease progression or unacceptable toxicity, or up to 24 months in patients without disease progression.
Microsatellite Instability-High (MSI-H) Cancer
KEYTRUDA is indicated for the treatment of adult and pediatric patients with unresectable or metastatic microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR)
- solid tumors that have progressed following prior treatment and who have no satisfactory alternative treatment options, or
