DARMSTADT, Germany, Jan. 20, 2021 –– Merck KGaA, Darmstadt, Germany, a leading science and technology company, today announced an update on the Phase III INTR@PID Lung 037 study and the extensive INTR@PID clinical trial program for the potential first-in-class investigational bifunctional immunotherapy bintrafusp alfa, in difficult-to-treat cancers, including biliary tract cancer (BTC) and cervical cancer.
The comprehensive INTR@PID program is designed to assess the impact of bintrafusp alfa across distinct cancers and settings where TGF-β is thought to play a driving role. TGF-β is a cytokine that is known to be associated with tumor propagation and metastatic potential such as local immunosuppression, fibrosis, growth of tumor blood vessels and chemo- or radiotherapy resistance through several mechanisms. Trapping TGF-β in the tumor microenvironment on top of PD-L1 blockade is thought to be transformative in different clinical settings.
While reviewing the totality of data from the ongoing clinical trial INTR@PID Lung 037 in the first-line treatment of patients with stage IV non-small cell lung cancer (NSCLC) that have high expression of PD-L1, the Independent Data Monitoring Committee recommended on January 19, 2021 to discontinue the clinical trial. Based on this recommendation, Merck KGaA, Darmstadt, Germany has made the decision to discontinue the clinical trial, as the study is unlikely to meet the co-primary endpoint, specifically progression-free survival. The recommendation by the Independent Data Monitoring Committee and the Company's decision is related only to this clinical trial.
"We have pioneered the science behind bintrafusp alfa, and now through a strategic alliance, multiple non-correlated parallel hypotheses are being evaluated across numerous indications in our extensive INTR@PID clinical program," said Danny Bar-Zohar, M.D., Global Head of Development for the Healthcare business of Merck KGaA, Darmstadt, Germany. "We remain committed to further evaluation of bintrafusp alfa, and these data from INTR@PID Lung 037 will provide important insights that may be applied to future studies."
Ongoing and New Clinical Trials
*Bintrafusp alfa is currently under clinical investigation and not approved for any use anywhere in the world.
About Biliary Tract Cancer (BTC)
BTCs are a group of rare, aggressive gastrointestinal cancers associated with poor outcomes and limited treatment options. There is currently no globally accepted standard of care in the second-line setting and chemotherapy as well as immunotherapies have demonstrated low response rates in BTC. Epithelial-to-mesenchymal transition (EMT), a hallmark of tumor progression and drug resistance, plays an important role in BTC and has been shown to be triggered by TGF-β signaling.
About Cervical Cancer
The human papillomavirus (HPV) is responsible for more than 90 percent of cervical cancer cases and is one of the most common and deadliest cancers among women worldwide. The TGF-β pathway is frequently dysregulated in HPV-associated malignancies, including cervical cancer, and may contribute to development and progression of cervical cancer and generating resistance to immunotherapy. There is no globally accepted standard-of-care treatment for recurrent/metastatic cervical cancer after first-line systemic therapy.
About Non-small Cell Lung Cancer (NSCLC)
Non-small cell lung cancer remains one of the leading causes of cancer deaths worldwide with low five-year survival rates. There has been significant treatment progress with checkpoint inhibitors, but a majority of patients don't respond.
About Bintrafusp Alfa
Bintrafusp alfa (M7824), discovered in-house at Merck KGaA, Darmstadt, Germany, and currently in clinical development through a strategic alliance with GSK, is a potential first-in-class investigational bifunctional fusion protein designed to simultaneously block two immunosuppressive pathways, TGF-β and PD-L1, within the tumor microenvironment. This bifunctional approach is thought to control tumor growth by potentially restoring and enhancing anti-tumor responses. In preclinical studies, bintrafusp alfa has demonstrated antitumor activity both as monotherapy and in combination with chemotherapy. Based on its mechanism of action, bintrafusp alfa offers a potential targeted approach to addressing the underlying pathophysiology of difficult-to-treat cancers.
About the INTR@PID Clinical Trial Program
INTR@PID is a global clinical trial program investigating the potential co-localized, dual inhibition of TGF-β and PD-L1 with bintrafusp alfa (M7824) in multiple tumor types. Current clinical trial information can be found on the INTR@PID website at www.intrapidclinicaltrials.com. To date, more than 1,300 patients with various types of solid tumors have been treated globally in the bintrafusp alfa INTR@PID clinical development program.
The INTR@PID clinical development strategy is comprehensive and is pursuing non-redundant hypotheses grounded in preclinical and early clinical data findings that continue to be explored and may yield clinically meaningful insights to patients in need, including exploring settings where simultaneous, synchronized targeting of TGF-β and PD-L1 may offer the key to expanding the potential of immunotherapy (lung cancer program); focusing on opportunities where PD-1/PD-L1 has suboptimal clinical activities and pathogenesis linked to TGF-β biology (studies in BTC and in urothelial cancers); and targeting specific tumors with biomarkers with a strong link to TGF-β signaling pathway (studies in TNBC and cervical cancer).
