European Commission Approves Merck’s KEYTRUDA® (pembrolizumab) Plus Chemotherapy as Treatment for Certain Patients With Locally Recurrent Unresectable or Metastatic Triple-Negative Breast Cancer (TNBC)

KEYTRUDA Is Now Approved in Combination With Chemotherapy as First-Line Treatment for Patients With Locally Recurrent Unresectable or Metastatic TNBC Whose Tumors Express PD-L1 (CPS ≥10) and Who Have Not Received Prior Chemotherapy for Metastatic Disease

KEYTRUDA Is the First Anti-PD-1 Therapy in Combination With Chemotherapy to Demonstrate Statistically Significant Overall Survival in These Patients; Based on Results From the Phase 3 KEYNOTE-355 Study

Merck known as MSD outside the United States and Canada, moment blazoned that the European Commission (EC) has approved KEYTRUDA, Merck’santi-PD-1 remedy, in combination with chemotherapy for the first- line treatment of locally intermittent unresectable or metastatic triadic-negative bone cancer (TNBC) in grown-ups whose excrescences express PD-L1 ( Combined Positive Score (CPS) ≥ 10) and who haven’t entered previous chemotherapy for metastatic complaint. Triadic-negative bone cancer is an aggressive type of bone cancer. This represents KEYTRUDA’s first blessing in Europe in a bone cancer setting.

The blessing is grounded on final analysis from the Phase 3 KEYNOTE-355 trial, in which KEYTRUDA in combination with chemotherapy ( nab-paclitaxel, paclitaxel or gemcitabine/ carboplatin) significantly bettered overall survival ( Zilches), reducing the threat of death by 27 (HR = 0.73 (95 CI,0.55-0.95); p = 0.0093), and progression-free survival (PFS), reducing the threat of complaint progression or death by 34 (HR = 0.66 (95 CI,0.50-0.88); p = 0.0018) compared to chemotherapy alone in these cases. In this trial, 38 of enrolled cases had excrescences expressing PD-L1 with CPS ≥ 10.
“ This blessing is an important corner for applicable cases with metastatic TNBC who are in need of new treatment options,” saidDr. Javier Cortés, head of the Transnational Bone Cancer Center (IBCC), Quironsalud Group. “ With this blessing, cases in Europe with metastatic TNBC whose excrescences express PD-L1 (CPS ≥ 10) have a new immunotherapy treatment option that can be used in combination with different chemotherapy agents.”

“ At Merck, we’re committed to perfecting issues for people with delicate-to- treat cancers, similar as TNBC, around the world and are proud of this first European blessing for KEYTRUDA in a bone cancer setting,” saidDr. Vicki Goodman, vice chairman, clinical exploration, Merck Research Laboratories. “ Now cases with metastatic TNBC who have excrescences that express PD-L1 (CPS ≥ 10) in Europe have the new option of KEYTRUDA in combination with chemotherapy, a authority that has shown significant enhancement in overall survival. Moment marks an important step forward in the treatment of this aggressive complaint.”
Data Supporting the European Blessing

The blessing was grounded on data from KEYNOTE-355 (NCT02819518), a multicenter, randomized, placebo- controlled, Phase 3 trial that enrolled 847 cases with locally intermittent unresectable or metastatic TNBC who hadn’t been preliminarily treated with chemotherapy in the advanced setting. Cases were randomized 21 to admit KEYTRUDA (200 mg every three weeks) plus chemotherapy ( investigator’s choice of paclitaxel, nab-paclitaxel or gemcitabine/ carboplatin) or placebo plus chemotherapy. Treatment with KEYTRUDA or placebo, both in combination with chemotherapy, continued until complaint progression, inferior toxin or a outside of 24 months. Cases could continue to be treated with chemotherapy, per standard of care. Cases could continue to be treated with KEYTRUDA beyond RECIST- defined complaint progression if the case was clinically stable and inferring clinical benefit as determined by the investigator. The binary primary efficacity outgrowth measures were OS and PFS. Secondary efficacity outgrowth measures included objective response rate and duration of response.
In the final analysis of the study, median Zilches was23.0 months (95 CI,19.0-26.3) with KEYTRUDA plus chemotherapy versus16.1 months (95 CI,12.6-18.8) with chemotherapy alone. Median PFS was9.7 months (95 CI,7.6-11.3) with KEYTRUDA plus chemotherapy versus5.6 months (95 CI,5.3-7.5) with chemotherapy alone.

The safety of KEYTRUDA in combination with chemotherapy has been estimated in cases withnon-small cell lung cancer (NSCLC), head and neck scaled cell melanoma (HNSCC), esophageal melanoma or TNBC entering 200 mg, 2 mg/ kg bodyweight (bw) or 10 mg/ kg bw KEYTRUDA every three weeks in clinical studies. In this patient population, the most frequent adverse responses were anemia (52), nausea (52), fatigue (37), constipation (34), neutropenia (33), diarrhea (32), dropped appetite (30) and puking (28). Frequentness of Grades 3-5 adverse responses were 67 for KEYTRUDA plus chemotherapy and 66 for chemotherapy alone in cases with NSCLC; 85 for KEYTRUDA plus chemotherapy and 84 for chemotherapy plus cetuximab in cases with HNSCC; 86 for KEYTRUDA plus chemotherapy and 83 for chemotherapy alone in cases with esophageal melanoma; and 78 for KEYTRUDA plus chemotherapy and 74 for chemotherapy alone in cases with TNBC.
About Triadic-Negative Bone Cancer

Triadic-negative bone cancer is a type of bone cancer that tests negative for estrogen hormone receptors, progesterone hormone receptors and overexpression of mortal epidermal growth factor receptor 2 (HER2). It’s an aggressive type of bone cancer that characteristically has a high rush rate within the first five times after opinion. Roughly 10-15 of cases with bone cancer are diagnosed with TNBC, which tends to be more common in people who are youngish than 40 times of age, who are Black or who have a BRCA1 mutation.
