NRG Fusion: Understanding

NRG Fusion: Overview

NRG1 Fusion is a genetic rearrangement involving the NRG1 gene, where it fuses with another gene, leading to the production of abnormal proteins that can drive tumor growth. These fusions activate the ERBB2/ERBB3 (HER2/HER3) signaling pathway, promoting cancer cell proliferation and survival. NRG1 fusions are rare but have been identified in various cancers, including Non-small cell lung cancer (NSCLC), Pancreatic cancer, Breast cancer, Colorectal cancer. NRG1 fusions are considered actionable mutations because they respond to targeted therapies such as HER2/HER3 inhibitors (e.g., afatinib, neratinib).

Neuregulin 1 (NRG1), also referred to as ARIA, HRG, GGF, or NDF, is a 44 kDa protein belonging to the epidermal growth factor (EGF) family. The NRG1 protein comprises several structural features, including an intracellular region, a transmembrane segment, a proximal membrane sequence, an extracellular EGF-like domain, an immunoglobulin-like domain, and specific amino acid sequences. The NRG1 gene has four main isoforms, designated as Type I through Type VI NRG1. All isoforms share two EGF-like domains, a and B, with the EGF-like receptor-binding domain located near the extracellular domain's proximal region, essential for activating ERBB receptor tyrosine kinases.

NRG1 is predominantly expressed in glial cells and neurons, as well as in organs like the mammary gland, heart, lungs, kidneys, and liver. It plays a vital role in the development of the nervous system, heart, and mammary tissue. Notably, NRG1B is highly expressed in the nervous system and cardiomyocytes, whereas NRG1a is more prevalent in mammary glands. Increasing evidence indicates that NRG1 fusions are strongly linked to the progression of various cancers.

NRG1 activates multiple intracellular signaling pathways, including ERK, PI3K/AKT, MAPK, PKC, and JAK-STAT, through interactions with ERBB receptors. This signaling cascade regulates cell proliferation, differentiation, and anti-apoptotic processes. In Schwann cells, NRG1 binds ERBB3/ERBB2 heterodimers, triggering pathways like Ras-ERK, PI3K/AKT, and PKC/NFAT, which influence cell survival, proliferation, migration, and differentiation.

NRG1 plays a critical role in neurological and cardiac functions, with abnormal expression and fusions linked to related disorders. The NRG1 fusion antibody drug JK07, developed by Salubris, is in Phase II clinical trials for chronic heart failure. While antibody drugs are expanding into non-traditional areas like cardiovascular and neurological diseases, no anti-NRG1 antibodies are currently in clinical development, presenting significant market potential. NRG1 fusions, although rare oncogenic drivers, have become a focus for targeted therapies. Zenocutuzumab (MCLA-128), a bispecific antibody, has shown promising results in pancreatic cancer patients with NRG1 fusions and received FDA Fast Track designation. With increasing research on NRG1 mechanisms, the development of NRG1-targeted therapies offers a promising future, especially in China, where the antibody drug market is rapidly growing.

Report Highlights:

• In December 2024, The US FDA granted accelerated approval to zenocutuzumab-zbco (brand name Bizengri) for adults with the following advanced, unresectable, or metastatic non-small cell lung cancer harboring a neuregulin 1 gene fusion with disease progression on or after prior systemic therapy, or advanced, unresectable, or metastatic pancreatic adenocarcinoma harboring a neuregulin 1 gene fusion with disease progression on or after prior systemic therapy.
• In December 2024, Merus N.V. and Partner Therapeutics, Inc. announced they had entered into an agreement in which Merus has exclusively licensed to PTx the right to commercialize zenocutuzumab (Zeno) for the treatment of NRG1 fusion-positive (NRG1+) cancer in the United States (U.S.).
• In November 2024, The FDA has extended the target action date under the Prescription Drug User Fee Act (PDUFA) for the biologics license application (BLA) seeking the approval of zenocutuzumab (MCLA-128) in the treatment of patients with NRG1-positive non-small cell lung cancer (NSCLC) and pancreatic cancer. The new PDUFA target action date is February 4, 2025.
• In May 2024, Merus N.V. announced that the U.S. Food and Drug Administration (FDA) had granted Priority review to a biologics license application (BLA) and accepted the BLA application for zenocutuzumab as a treatment for patients with NRG1 fusion-positive non-small cell lung cancer (NSCLC) and pancreatic ductal adenocarcinoma (PDAC).

NRG Fusion: Company and Product Profiles (Marketed Therapies)

1. Company Overview: Merus

Merus is a clinical-stage oncology company developing innovative full-length human bispecific and trispecific antibody therapeutics, referred to as Multiclonics(R). Multiclonics(R) are manufactured using industry standard processes and have been observed in preclinical and clinical studies to have several of the same features of conventional human monoclonal antibodies, such as long half-life and low immunogenicity

Product Description: OPZELURA

Zeno is an antibody-dependent cell-mediated cytotoxicity (ADCC)-enhanced Biclonics(R) that utilizes the Merus Dock & Block(R) mechanism to inhibit the neuregulin/HER3 tumor-signaling pathway in solid tumors with NRG1 fusions (NRG1+ cancer). Through its unique mechanism of binding to HER2 and potently blocking the interaction of HER3 with its ligand NRG1 or NRG1-fusion proteins, Zeno has the potential to be particularly effective against NRG1+ cancer. In preclinical studies, Zeno potently inhibits HER2/HER3 heterodimer formation thereby inhibiting oncogenic signaling pathways, leading to inhibition of tumor cell proliferation and blocking tumor cell survival. The drug was granted accelerated approval by US FDA for the treatment of adults with advanced unresectable or metastatic pancreatic adenocarcinoma harboring a neuregulin 1 (NRG1) gene fusion with disease progression on or after prior systemic therapy.

NRG Fusion: Company and Product Profiles (Pipeline Therapies)

1. Company Overview: Hummingbird Bioscience

Hummingbird Bioscience is a precision bio therapeutics company discovering and developing transformative biologics for hard-to-treat diseases. To address key challenges with current antibody-drug conjugate (ADC) therapies, Hummingbird Bioscience is building a pipeline of next-generation ADCs using its proprietary antibody discovery and linker/payload platforms. The company approach combines computational and systems biology with wet lab drug discovery in a multi-disciplinary, collaborative environment spanning initial discovery through clinical development. The company harnesses this integrated approach across target identification and patient selection, enabling the team to increase the efficiency of translating novel scientific insights while reducing the inherent risk in drug discovery and development.

Product Description: HMBD-001

HMBD-001 is an IgG1 antibody designed to target HER3, discovered using Hummingbird Bioscience's proprietary Rational Antibody Discovery (RAD) platform. The company believe HMBD-001 is the only anti-HER3 antibody in development that has the potential to fully block both ligand-dependent and -independent HER3 activation and oncogenic signaling, by targeting a key epitope located at the interface where HER3 forms heterodimers with HER2 or EGFR. In preclinical models evaluating HMBD-001, superior affinity and more potent tumor growth inhibition compared to existing anti-HER3 antibodies were observed. Currently the drug is in Phase I/II stage of its development for the treatment of sqNSCLC and mCRPC.
