Merck Receives Priority Review From FDA for New Drug Application for HIF-2? Inhibitor Belzutifan (MK-6482)

On March 16, 2021 Merck (NYSE: MRK), known as MSD outside the United States and Canada, reported that the U.S. Food and Drug Administration (FDA) has accepted and granted priority review for a New Drug Application (NDA) for the hypoxia-inducible factor-2 alpha (HIF-2α) inhibitor belzutifan (pronounced bell-ZOO-ti-fan), a novel investigational candidate in Merck’s oncology pipeline, for the potential treatment of patients with von Hippel-Lindau (VHL) disease-associated renal cell carcinoma (RCC), not requiring immediate surgery (Press release, Merck & Co, MAR 16, 2021, View Source [SID1234576713]). This NDA is based on data from the Phase 2 Study-004 trial, in which belzutifan showed a confirmed overall response rate of 36.1% (n=22/61) (95% CI: 24.2-49.4) in patients with VHL disease-associated RCC. The FDA has set a Prescription Drug User Fee Act (PDUFA), or target action, date of September 15, 2021.

"Von Hippel-Lindau disease is a rare genetic condition for which there is no systemic treatment option available and is associated with a high risk of cancer development in multiple organs. In fact, up to 70% of patients with VHL develop renal cell carcinoma during their lifetime," said Dr. Scot Ebbinghaus, vice president, clinical research, Merck Research Laboratories. "This priority review validates the important progress we have made to expand and diversify Merck’s oncology pipeline with innovative, new therapeutic approaches. We look forward to working closely with the FDA to bring belzutifan to patients in need."

Merck is also studying belzutifan in advanced RCC and other tumor types through a broad clinical program. In addition to the ongoing Phase 2 Study-004 trial, belzutifan is being evaluated in Phase 3 trials as monotherapy and as part of a combination regimen in previously treated patients and as part of a combination regimen as a first-line treatment for advanced clear cell RCC.

About the Phase 2 Study-004 Trial

This application is based on data from Study-004 (ClinicalTrials.gov, NCT03401788), which is a Phase 2, open-label trial evaluating belzutifan for the potential treatment of patients with VHL disease who had at least one measurable solid tumor localized to the kidney and who did not require immediate surgery. The study enrolled 61 patients who received belzutifan 120 mg orally once daily until disease progression or unacceptable toxicity. The primary endpoint was objective response rate in VHL disease-associated RCC. Secondary endpoints in RCC tumors include disease control rate, duration of response, time to response, progression-free survival, time to surgery and safety.

Additionally, this study evaluated response rates in other common VHL disease-associated tumors, including pancreatic cysts, pancreatic neuroendocrine tumors, central nervous system (CNS) hemangioblastomas, and retinal hemangioblastomas.

About Belzutifan

Belzutifan (MK-6482) is a novel, potent and selective inhibitor of HIF-2α. Proteins known as hypoxia-inducible factors, including HIF-2α, can accumulate in patients when VHL, a tumor-suppressor protein, is inactivated. If not properly regulated, the accumulation of HIF-2α can stimulate several oncogenes associated with cellular proliferation, angiogenesis and tumor growth, leading to the growth of both benign and malignant tumors. This inactivation of VHL has been observed in more than 90% of clear cell RCC tumors. Research into VHL biology that led to the discovery of HIF-2α was awarded the Nobel Prize in Physiology or Medicine in 2019.

About Von Hippel-Lindau Disease and Renal Cell Carcinoma

Von Hippel-Lindau disease is a rare genetic disease that affects one in 36,000 people (200,000 cases worldwide and 10,000 cases in the U.S. alone). Patients with VHL disease are at risk for benign blood vessel tumors as well as several cancers, including RCC. As many as 70% of people with VHL disease develop RCC.

Renal cell carcinoma is by far the most common type of kidney cancer; about nine of 10 kidney cancers are RCCs, and about seven of 10 RCCs are clear cell. Worldwide, it is estimated there were nearly 431,300 cases of kidney cancer diagnosed and almost 179,400 deaths from the disease in 2020. In the U.S. alone, it is estimated there will be almost 76,100 new cases of kidney cancer diagnosed and nearly 13,800 deaths from the disease in 2021.

Merck Reports Topline Data for Bintrafusp Alfa as Second-Line Monotherapy Treatment in Biliary Tract Cancer

On March 16, 2021 Merck, a leading science and technology company, reported that topline data from the Phase II INTR@PID BTC 047 study evaluating bintrafusp alfa as a monotherapy in the second-line treatment of patients with locally advanced or metastatic biliary tract cancer (BTC) who have failed or are intolerant of first-line platinum-based chemotherapy (Press release, Merck & Co, MAR 16, 2021, View Source [SID1234576709]).

In the study of 159 patients, bintrafusp alfa demonstrated single-agent efficacy and durability with a manageable safety profile after more than nine months of follow-up, with an Independent Review Committee (IRC)-adjudicated objective response rate (ORR) of 10.1% (95% CI: 5.9% to 15.8%) per RECIST 1.1. Though single-agent activity was observed, the study did not meet the pre-defined threshold that would have enabled regulatory filing for BTC in the second line setting. The results will be submitted for presentation at an upcoming medical meeting or publication.

"Given the high unmet treatment need in BTC, where single agent immunotherapy in PD-L1 all comers has shown an ORR of 5.8%, we are encouraged by the single agent clinical activity of bintrafusp alfa in this study as a second-line treatment," said Milind Javle, MD, professor of GI medical oncology, MD Anderson Cancer Center, and an investigator for the INTR@PID BTC 047 study. "The bintrafusp alfa 047 study is one of the most important clinical investigations conducted for chemo-refractory biliary cancers, and I would like to thank the patients, families, and study team for their valuable participation."

"This study demonstrates single-agent activity with bintrafusp alfa in locally advanced or metastatic BTC, a disease that has been historically difficult to treat," said Danny Bar-Zohar, M.D., Global Head of Development for the Healthcare business sector of Merck. "The data will contribute to our understanding of addressing both TGF-β and PD-L1 inhibition in the tumor microenvironment."

A Phase II/III study of bintrafusp alfa in combination with chemotherapy as a first-line treatment for BTC (INTR@PID BTC 055), which is assessing a different hypothesis than the second-line monotherapy study, has completed enrollment in the Phase II portion and is currently ongoing.

*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 Bintrafusp Alfa

Bintrafusp alfa (M7824), discovered in-house at Merck, 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, globally more than 1,300 patients with various types of solid tumors have received bintrafusp alfa in the 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; focusing on opportunities where PD-1/PD-L1 has suboptimal clinical activities and pathogenesis linked to TGF-β biology; and targeting specific tumors with biomarkers with a strong link to TGF-β signaling pathway.

NRG1 gene fusions are oncogenic driver alterations that have recently been identified in over 10 solid tumor types, with an overall estimated incidence of 0.2% in all solid tumors.1 Though rare, gene fusions are a proven target for precision oncology therapeutics, with over a dozen FDA-approved therapies now available for both hematologic and solid tumors driven by various gene fusions.2

"Our collaboration with Elevation Oncology reflects our shared pursuit of matching cancer patients to clinical trials and therapies that are precisely targeted to their unique tumor types and genomic biomarkers," said Douglas M. VanOort, Chairman and Chief Executive Officer of NeoGenomics. "Through cross-industry collaborations, we enable greater efficiency in the development and delivery of the latest advancements in both diagnostics and targeted therapies. Together, we work towards a future where every patient living with cancer has the opportunity to benefit from precision medicine."

As part of its comprehensive oncology test menu, NeoGenomics offers a variety of gene fusion panels that leverage RNA-based NGS to detect translocations and fusions with known and novel fusion partners across all solid tumors, including actionable gene fusions such as in ALK, BRAF, FGFR, NRG1, NTRK, PDGF, RET, and ROS1. In addition to all solid tumor panels, targeted panels are available in tumor types where gene fusions are commonly enriched:

Lung NGS Fusion Panel (Complete or Limited)
Cholangio/Pancreatic Carcinoma NGS Fusion Panel
Prostate NGS Fusion Panel
Thyroid NGS Fusion Panel
Targeted Solid Tumor NGS Fusion Panel
Universal Solid Tumor NGS Fusion Panel
RNA-based sequencing is the most sensitive detection method for structural variants that span large intronic regions, such as those leading to NRG1 gene fusions, which may not be detectable by most DNA-based sequencing techniques reliant on short-read methods. In addition, the use of RNA-based NGS furthers the scientific understanding of gene fusions by enabling full characterization of gene fusion partners and nucleotide-level resolution of fusion junctions.

"Accurate and widespread identification of gene fusions is critical to ensure patients can be matched to the growing number of approved and investigational precision therapies for these key oncogenic drivers," said Shawn Leland, PharmD, RPh, Founder and CEO of Elevation Oncology. "We are pleased to partner with NeoGenomics to ensure that across any solid tumor, each positive NRG1 fusion test result has the potential to be met with an actionable therapeutic opportunity in our Phase 2 CRESTONE study."

Patients and physicians can learn more about the CRESTONE study at www.nrg1fusion.com or on www.ClinicalTrials.gov under the NCT number NCT04383210.
