Executive Vice President and President, Merck Research Laboratories at Merck & Co., Inc.
Thank you, Caroline. Good morning. Today, I will provide notable R&D updates since our last earnings call and a brief summary of 2023 accomplishments. Momentum in the pipeline remains strong. Progress is spanning both early- and late-phase programs across multiple therapeutic areas. Starting with oncology. We are diversifying our portfolio and executing on our strategy, which is broadly based on three strategic pillars: immuno-oncology; precision molecular targeting; and tissue targeting. In immuno-oncology, we remain committed to the development of KEYTRUDA and further transforming cancer care to address the needs of certain patients. In the fourth quarter, we received approvals from both the FDA and the European Commission in two gastrointestinal indications: one in combination with chemotherapy for the first-line treatment of adults with locally-advanced unresectable or metastatic HER2-negative gastric or gastroesaphageal junction adenocarcinoma based on KEYNOTE-A59; and another in combination with gemcitabine and cisplatin for the treatment of patients with locally-advanced unresectable or metastatic biliary tract cancer based on KEYNOTE-966.
As we continue to harness the potential of KEYTRUDA, we have an increased focus on earlier stages of disease, where we believe timely, effective intervention may significantly improve patient outcomes. Last month, we announced FDA approval for KEYTRUDA in combination with chemo radiotherapy for the treatment of FIGO Stage III through IVa cervical cancer based on the Phase III KEYNOTE-A18 trial. This is an important advancement and provides a new option that has potential to become the standard of care. To date, with all the research conducted with checkpoint inhibitors, the only studies to have demonstrated statistically significant overall survival benefit in earlier-stage cancers are KEYTRUDA-based regimens: KEYNOTE-671 as part of a neoadjuvant followed by post-surgery adjuvant treatment regimen for certain patients with resectable non-small cell lung cancer and KEYNOTE-564 as a post-surgery adjuvant treatment regimen for certain patients with renal cell carcinoma. Since the approval of a KEYNOTE-671 in October, it is notable that the American Cancer Society released guidance recommending that certain individuals with significant smoking history undergo an annual low-dose CT scan.
The guidance also expands the age range for lung cancer screening. We look forward to the opportunity to help impact patients and support the identification of more patients at risk. Additional data from KEYNOTE-564 demonstrating an overall survival benefit were presented at the ASCO GU conference last week. Detailed findings from KEYNOTE-123 evaluating KEYTRUDA for the adjuvant treatment of patients with localized, muscle-invasive and locally-advanced resectable urothelial carcinoma demonstrating a disease-free survival benefit versus observation were also presented at ASCO GU. Also in the earlier-stage setting, along with our partner, Moderna, we announced 3-year recurrent-free survival and distant metastasis-free survival data for our individualized neoantigen therapy, V940, in combination with KEYTRUDA for the adjuvant treatment of Stage III and IV melanoma following complete resection. We are encouraged by the durability of the responses observed and the potential for this regimen to impact patients earlier in their diagnosis. The Phase III trials in the adjuvant setting for certain patients with melanoma and non-small cell lung cancer are actively enrolling. Progress continues in precision oncology.
The FDA approval for WELIREG, our HIF2 alpha inhibitor for the treatment of adults with advanced RCC following a PD-1 or PD-L1 inhibitor and a VEGF-TKI, marks the first drug approved in a new therapeutic class for eligible patients with advanced renal cell carcinoma in nearly a decade and builds on the 2021 approval for the treatment of adults with certain von Hippel-Lindau disease-associated tumors. Additional Phase III studies for WELIREG, in combination with KEYTRUDA and/or lenvatinib for the treatment of certain types of renal cell carcinoma in the advanced and adjuvant settings, are ongoing. Finally, moving to the tissue targeting space. Together with Astellas and Seagen, now Pfizer, we announced the FDA approval for KEYTRUDA in combination with PADCEV, a Nectin-4-targeting ADC for the first-line treatment to patients with locally advanced or metastatic urothelial cancer based on results from KEYNOTE-A39. These results demonstrated a superior overall survival benefit versus gemcitabine plus cisplatin or carboplatin and extend our pioneering work in combining KEYTRUDA with chemotherapy as well as reinforcing the value of an ADC to enable targeted delivery of chemotherapy to the tumor tissue.
Following the announcement of our collaboration with Daiichi Sankyo in October, we are pleased to receive priority review from the FDA for MK-1022, or patritumab deruxtecan, our investigation of a fully humanized anti-HER3 ADC for patients with advanced EGFR-mutated non-small cell lung cancer previously treated with two or more systemic therapies. The agency has set a target action date of June 26. Through our agreements with Kelun and Daiichi Sankyo as well as our own discovery programs, we have established a robust pipeline of tissue-targeting ADCs. And the recently announced acquisition of Harpoon Therapeutics provides the opportunity to help complement and strengthen our approach by providing a portfolio of novel T cell engagers, the most significant of which is HPN-328, an investigational delta-like ligand three targeting T cell engager being evaluated in small cell lung cancer and neuroendocrine tumors. Our strong diverse portfolio of immuno-oncology precision molecular and tissue-targeting agents positions us well to have a profound impact on even more patients long into the future. Next to our Vaccine pipeline.
We are making notable advancements with our population-specific vaccine program for pneumococcal disease. The FDA has accepted for priority review the new biologics license application for V116, our 21-valent pneumococcal conjugate vaccine, specifically designed for adults supported by results from multiple Phase III clinical trials evaluating V116 in both pneumococcal vaccine-naive and vaccine-experienced adult patient population. Results from STRIDE-3 trial were presented at the World Vaccine Congress West Coast in November and additional data from STRIDE-3 as well as STRIDE studies 4, five and six will be presented at the International Society of Pneumonia and Pneumococcal Disease Congress in March. If approved, as Rob noted, V116 would be the first new pneumococcal-conjugate vaccine specifically designed to address the serotypes responsible for approximately 83% of invasive pneumococcal disease in adults 65 years of age and older, according to CDC data from 2018 to 2021. Importantly, V116 includes eight unique serotypes, which account for 30% of disease according to the same CDC data. These serotypes are not covered by currently licensed pneumococcal vaccine options. The FDA has set a target action date of June 17.
Turning to programs in the cardiometabolic disease pipeline. We are eager to bring sotatercept to patients as an important treatment option for pulmonary arterial hypertension. The FDA has set a target action date of March 26. Beyond data from the STELLAR trial, we have the Phase III ZENITH and HYPERION studies, which are evaluating sotatercept in patients with more advanced disease and those earlier on their disease journey. In addition, the Phase II CADENCE trial will evaluate WHO Group II pulmonary hypertension focused on a type of left heart disease. As we close out 2023, it is important to highlight our significant progress and execution across therapeutic areas and modalities as well as multiple business development transactions. In the year, we have more than 25 regulatory approvals in major markets. We also initiated over 20 Phase III studies across multiple new classes of assets, including in oncology with bomedemstat, our LSD1 inhibitor in essential thrombocythemia; nemtabrutinib, our BTK inhibitor in first-line chronic lymphocytic leukemia or small lymphocytic lymphoma; MK-2870, our TROP2 ADC in collaboration with Kelun in non-small cell lung cancer and endometrial carcinoma; MK-5284, our CYP11A1 inhibitor in collaboration with Orion in metastatic castrate-resistant prostate cancer; and V940 in collaboration with Moderna for the adjuvant treatment of certain types of melanoma and non-small cell lung cancer.
Also in immunology, with tulisokibart in ulcerative colitis. Finally, in cardiometabolic disease with multiple trials for MK-0616 in hypercholesterolemia. As a result of the increasing depth and breadth of our pipeline, we are planning to initiate an even greater number of Phase III trials in 2024. Considerable credit goes to my colleagues across the organization for their hard work and unwavering dedication. We are executing on our science-led strategy and look forward to providing further updates on our progress throughout the year. And now I will turn the call back to Peter.
