Gastroesophageal junction adenocarcinoma

BeiGene’s Tevimbra (tislelizumab) has been recommended by the European Medicines Agency’s human medicines committee as a first-line treatment for gastric and oesophageal cancer patients. The Committee for Medicinal Products for Human Use (CHMP) has recommended that the PD-1 inhibitor be used in combination with platinum- and fluoropyrimidine-based chemotherapy to treat adults with HER2-negative locally advanced unresectable or metastatic gastric or gastroesophageal junction (G/GEJ) adenocarcinoma, and in combination with platinum-based chemotherapy to treat adults with unresectable, locally advanced or metastatic oesophageal squamous cell carcinoma (ESCC). Those eligible for the drug will also have tumours that express PD-L1 with a tumour area positivity (TAP) score of at least 5%, according to the recommendations. Gastric cancer is the fifth leading cause of cancer-related deaths globally, while oesophageal cancer is the sixth. Tevimbra is already approved in the EU for certain cases of advanced or metastatic ESCC after prior platinum-based chemotherapy, and for three non-small cell lung cancer indications covering both the first- and second-line settings. The CHMP’s decision for Tevimbra in G/GEJ cancer was based on positive results from the late-stage RATIONALE-305 trial, in which BeiGene’s drug in combination with investigator’s choice of chemotherapy resulted in a 20% reduction in the risk of death compared to placebo plus chemotherapy in patients with advanced unresectable or metastatic G/GEJ cancer. This benefit rose for patients expressing PD-L1 with a TAP score of at least 5%, with Tevimbra-chemotherapy demonstrating a 29% reduction in the risk of death compared to the placebo arm in this population. The committee’s recommendation in ESCC was supported by results from the phase 3 RATIONALE-306, which showed a 34% reduction in the risk of death for Tevimbra in combination chemotherapy versus placebo plus chemotherapy for patients unresectable, locally advanced recurrent or metastatic ESCC. Three-year overall survival in patients expressing PD-L1 with a TAP score of at least 5% was also substantially improved in favour of the Tevimbra arm, demonstrating a 38% reduction in the risk of death. Mark Lanasa, chief medical officer, solid tumours at BeiGene, said: “With these CHMP opinions, we are one step closer to bringing this innovative therapy to eligible patients with untreated G/GEJ cancer and ESCC, who face a poor prognosis and limited treatment options.” The European Commission will now consider the CHMP’s recommendations as it makes a final decision on Tevimbra in these indications.

The INTerpath-009 clinical trial demonstrates continued expansion of the INTerpath clinical program, as the third Phase 3 trial for the investigational individualized neoantigen therapy, V940 (mRNA-4157), focused on earlier stages of cancer RAHWAY, NJ & CAMBRIDGE, MA, USA I October 28, 2024 I Merck (NYSE: MRK), known as MSD outside of the United States and Canada, and Moderna, Inc. (Nasdaq: MRNA), today announced the initiation of INTerpath-009, a pivotal Phase 3 randomized clinical trial evaluating V940 (mRNA-4157), an investigational individualized neoantigen therapy (INT), in combination with KEYTRUDA ® (pembrolizumab), Merck’s anti-PD-1 therapy, as adjuvant treatment for patients with resectable Stage II, IIIA or IIIB (N2) non-small cell lung cancer (NSCLC) who did not achieve a pathological complete response (pCR) after receiving neoadjuvant KEYTRUDA plus platinum-based chemotherapy. Global recruitment in INTerpath-009 has begun, and the first patients have now started enrolling in Canada. “While the overall survival rates for patients with non-small cell lung cancer have significantly improved in recent years, lung cancer continues to be the leading cause of cancer death worldwide,” said Dr. Marjorie Green, senior vice president and head of oncology, global clinical development, Merck Research Laboratories. “We are pleased to expand the INTerpath clinical trial program with Moderna, evaluating V940 (mRNA-4157), a promising new modality, in combination with KEYTRUDA to pursue meaningful advances for lung cancer and bring more options to patients with earlier stages of disease, where we potentially can have the most impact.” “We are excited to build on our ongoing collaboration with our colleagues at Merck by expanding our research efforts for patients with NSCLC,” said Kyle Holen, M.D., Moderna’s senior vice president and head of development, Therapeutics and Oncology. “We believe that our mRNA technology has the potential to improve the outcomes of those affected by lung cancer and together, INTerpath-002 and INTerpath-009 are designed to demonstrate this potential in early-stage lung cancer, with and without prior neoadjuvant therapy.” Ongoing clinical development programs Merck and Moderna have initiated Phase 3 randomized clinical trials evaluating mRNA-4157 (V940) in combination with KEYTRUDA as an adjuvant treatment in patients with resected high-risk (Stage IIB-IV) melanoma (INTerpath-001, NCT05933577 ) and non-small cell lung cancer (INTerpath-002, NCT06077760 ). In 2024, Merck and Moderna also initiated a two-part Phase 2/3 randomized clinical trial evaluating mRNA-4157 (V940) in combination with KEYTRUDA as neoadjuvant and adjuvant treatment in patients with resectable locally advanced Stage II-IV (M0) cutaneous squamous cell carcinoma (INTerpath-007, NCT06295809 ), a Phase 2 randomized clinical trial evaluating mRNA-4157 (V940) in combination with KEYTRUDA as adjuvant treatment in patients with intermediate-high-risk, high-risk, or M1 no evidence of disease renal cell carcinoma (INTerpath-004, NCT06307431 ), and a Phase 2 randomized clinical trial evaluating mRNA-4157 (V940) in combination with KEYTRUDA as adjuvant treatment in patients with high-risk muscle-invasive urothelial carcinoma post-radical resection (INTerpath-005, NCT06305767 ). About mRNA-4157 (V940) mRNA-4157 (V940) is a novel investigational messenger RNA (mRNA)-based individualized neoantigen therapy (INT) consisting of a synthetic mRNA coding for up to 34 neoantigens that is designed and produced based on the unique mutational signature of the DNA sequence of the patient’s tumor. Upon administration into the body, the algorithmically derived and RNA-encoded neoantigen sequences are endogenously translated and undergo natural cellular antigen processing and presentation, a key step in adaptive immunity. Individualized neoantigen therapies are designed to train and activate an antitumor immune response by generating specific T-cell responses based on the unique mutational signature of a patient’s tumor. KEYTRUDA is an immunotherapy that works by increasing the ability of the body’s immune system to help detect and fight tumor cells. As previously announced from the Phase 2b KEYNOTE-942/mRNA-4157-P201 trial evaluating patients with high-risk stage III/IV melanoma, combining mRNA-4157 (V940) with KEYTRUDA may provide a meaningful benefit over KEYTRUDA alone. Merck and Moderna continue to evaluate and expand the V940 INTerpath clinical development program for additional tumor types and treatment settings. About INTerpath-009 ( NCT06623422 ) INTerpath-009 is a global, randomized, double-blind Phase 3 trial evaluating 680 patients with resected (R0 or R1) Stage II, IIIA, IIIB (N2) NSCLC who did not achieve a pCR after neoadjuvant KEYTRUDA plus platinum-based chemotherapy. Following surgical resection, participants 18 years and older will be randomized 1:1 to receive either V940 (mRNA-4157) (1 mg every three weeks for up to nine doses) and KEYTRUDA (400 mg every six weeks up to seven cycles) or placebo (1 mg every three weeks for up to nine doses) and KEYTRUDA (400 mg every six weeks up to seven cycles). The primary endpoint is disease-free survival (DFS), defined as the time from randomization to any recurrence (local, locoregional, regional, or distant), occurrence of new primary NSCLC, as assessed by the investigator, or death due to any cause, whichever occurs first. The secondary endpoints are overall survival (OS), distant metastasis-free survival (DMFS), DFS2, lung cancer-specific survival (LCSS), safety, and quality of life. Key eligibility criteria for the trial include: patients who have histologically/cytologically confirmed diagnosis of Stage II, IIIA, or IIIB (N2) NSCLC (American Joint Committee on Cancer [AJCC] 8th Edition), have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1, no pCR by local testing after neoadjuvant chemotherapy plus KEYTRUDA, completed surgery, with no disease by baseline imaging , and exclude epidermal growth factor receptor (EGFR) mutation. For further information, please see the clinicaltrials.gov page for INTerpath-009. About lung cancer Lung cancer is the leading cause of cancer death worldwide. In 2022 alone, there were approximately 2.4 million new cases and 1.8 million deaths from lung cancer globally. Non-small cell lung cancer is the most common type of lung cancer, accounting for about 80% of all cases. In 2024, the overall five-year survival rate for patients diagnosed with lung cancer is 25% in the United States. Improved survival rates are due, in part, to earlier detection and screening, reduction in smoking, advances in diagnostic and surgical procedures, as well as the introduction of new therapies. Early detection and screening remain an important unmet need, as 44% of lung cancer cases are not found until they are advanced. 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.

KEYTRUDA plus chemotherapy is the first approval in the EU for an anti-PD-1 therapy combined with chemotherapy only for patients with primary advanced or recurrent endometrial carcinoma regardless of mismatch repair status KEYTRUDA plus chemoradiotherapy is the first anti-PD-1-based regimen approved in the EU for patients with FIGO 2014 Stage III-IVA locally advanced cervical cancer RAHWAY, NJ, USA I October 24, 2024 I Merck (NYSE: MRK), known as MSD outside of the United States and Canada, today announced that the European Commission (EC) has approved two new indications for KEYTRUDA ® (pembrolizumab), Merck’s anti-PD-1 therapy, in gynecologic cancers. The first approval is for KEYTRUDA, in combination with carboplatin and paclitaxel, for the first-line treatment of primary advanced or recurrent endometrial carcinoma in adults who are candidates for systemic therapy. The second approval is for KEYTRUDA, in combination with chemoradiotherapy (CRT), for the treatment of FIGO (International Federation of Gynecology and Obstetrics) 2014 Stage III-IVA locally advanced cervical cancer in adults who have not received prior definitive therapy. With these decisions, KEYTRUDA is now approved for 30 indications in the EU, including five in gynecologic cancers – three in endometrial cancer and two in cervical cancer. “These KEYTRUDA-based regimens have the potential to change the treatment paradigm for people with endometrial and cervical cancer, two of the most commonly diagnosed cancers among women in Europe,” said Dr. Gursel Aktan, vice president, global clinical development, Merck Research Laboratories. “These approvals underscore the continued expansion of the use of KEYTRUDA in diverse patient populations and treatment settings with utility of KEYTRUDA ranging from earlier lines of therapy to treating advanced disease.” The EC approvals are based on results from the Phase 3 NRG-GY018 trial, also known as KEYNOTE-868, and the Phase 3 KEYNOTE-A18 trial, also known as ENGOT-cx11/GOG-3047, respectively, and follow positive recommendations from the Committee for Medicinal Products for Human Use received in September 2024 . In NRG-GY018/KEYNOTE-868, KEYTRUDA in combination with carboplatin and paclitaxel, followed by KEYTRUDA as a single agent, demonstrated a statistically significant and clinically meaningful improvement in progression-free survival (PFS) compared to chemotherapy alone. In KEYNOTE-A18, KEYTRUDA in combination with concurrent CRT demonstrated statistically significant and clinically meaningful improvements in overall survival (OS) and PFS compared to concurrent CRT alone for newly diagnosed patients with FIGO 2014 Stage III-IVA locally advanced cervical cancer. These approvals allow marketing of these KEYTRUDA regimens for these indications in all 27 EU member states, as well as Iceland, Liechtenstein, Norway and Northern Ireland. Timing for commercial availability of KEYTRUDA for these indications in individual EU countries will depend on multiple factors, including the completion of national reimbursement procedures. In June 2024 , KEYTRUDA in combination with carboplatin and paclitaxel, followed by KEYTRUDA as a single agent, was approved in the U.S. for the treatment of adult patients with primary advanced or recurrent endometrial carcinoma based on PFS results from the NRG-GY018 trial. The KEYTRUDA regimen reduced the risk of disease progression or death by 70% (HR=0.30 [95% CI, 0.19-0.48]; p<0.0001) in patients whose cancer was mismatch repair deficient (dMMR) and by 40% (HR=0.60 [95% CI, 0.46-0.78]; p<0.0001) in patients whose cancer was mismatch repair proficient (pMMR) compared to placebo with carboplatin and paclitaxel followed by placebo alone. In January 2024 , KEYTRUDA in combination with CRT was approved in the U.S. for the treatment of patients with FIGO 2014 Stage III-IVA cervical cancer based on PFS results from the KEYNOTE-A18 trial. The KEYTRUDA regimen reduced the risk of disease progression or death by 41% (HR=0.59 [95% CI, 0.43-0.82]) versus concurrent CRT alone for these patients. About NRG-GY018/KEYNOTE-868 NRG-GY018, also known as KEYNOTE-868, is a randomized, double-blind, placebo-controlled Phase 3 trial (ClinicalTrials.gov, NCT03914612 ) evaluating KEYTRUDA in combination with standard of care chemotherapy (paclitaxel and carboplatin) versus placebo plus standard of care chemotherapy for the treatment of measurable stage III, IVA, IVB or recurrent endometrial cancer in pMMR and dMMR cohorts. The primary endpoint is PFS, and secondary endpoints include overall survival, objective response rate (ORR), duration of response and safety. The trial enrolled 810 patients who were randomized (1:1) to receive either: About KEYNOTE-A18 KEYNOTE-A18, also known as ENGOT-cx11/GOG-3047, is a randomized, double-blind Phase 3 trial (ClinicalTrials.gov, NCT04221945 ) sponsored by Merck and conducted in collaboration with the European Network for Gynecological Oncology Trial (ENGOT) groups and the GOG Foundation, Inc. (GOG) investigating KEYTRUDA in combination with CRT (cisplatin and external beam radiotherapy [EBRT] followed by brachytherapy [BT]) compared to placebo plus concurrent CRT for the treatment of newly diagnosed high-risk (stage IB2-IIB with lymph node-positive disease, and stage III-IVA with and without lymph node-positive disease) locally advanced cervical cancer where patients are treated with definitive intent. The primary endpoints are PFS and OS, and secondary endpoints include complete response rate, ORR and safety. The trial enrolled 1,060 patients with cervical cancer who had not previously received any definitive surgery, radiation, or systemic therapy for cervical cancer. Patients were randomized (1:1) to receive either: About endometrial carcinoma Endometrial carcinoma begins in the inner lining of the uterus, which is known as the endometrium, and is the most common type of cancer in the uterus. Globally, endometrial cancer is the sixth most common cancer in women and 15 th most common cancer overall. Worldwide, it is estimated there were approximately 420,368 patients diagnosed with endometrial cancer and 97,723 patient deaths from the disease in 2022. In Europe, it is estimated there were approximately 124,874 patients diagnosed with endometrial cancer and 30,272 patient deaths from the disease in 2022. About cervical cancer Cervical cancer forms in the cells lining the cervix, which is the lower part of the uterus. All women are at risk for cervical cancer, and it is most frequently diagnosed between the ages of 35 and 44. While screenings and prevention have resulted in declining cervical cancer rates, the disease continues to affect many people in the U.S. and around the world. Cervical cancer is the fourth most common cancer in women globally. Worldwide, it is estimated there were approximately 662,301 patients diagnosed with cervical cancer and 348,874 patient deaths from the disease in 2022. In Europe, it is estimated there were approximately 58,219 new cases of cervical cancer diagnosed and 26,950 patient deaths from the disease in 2022. About Merck’s research in women’s cancers Merck is advancing research aimed at expanding treatment options for certain breast and gynecologic (ovarian, cervical and endometrial) cancers, with a goal of improving outcomes for more patients affected by these diseases. Breast cancer and gynecological cancers are the first and second most commonly occurring cancer types among women worldwide, respectively, and Merck aims to give patients facing these devastating diseases options. With more than 20 clinical trials in more than 18,000 patients around the world, Merck is driving innovative research to purposefully advance standards of care in women’s cancers. Merck’s research efforts include trials focused on evaluating its medicines in earlier stages, as well as identifying novel mechanisms and new combinations with these treatments. Merck is working to develop a portfolio and pipeline to address the impact of women’s cancers on patients, their families and communities globally.
