Understanding NADPH Oxidase (NOX) Replacement Therapies
NADPH Oxidase (NOX) Overview
NADPH oxidases (NOX enzymes) are a family of membrane-bound enzymes responsible for producing reactive oxygen species (ROS), which play essential roles in host defense, cell signaling, and tissue homeostasis. Among the seven NOX isoforms (NOX1–5, DUOX1, DUOX2), NOX2 is the most well-characterized, particularly for its role in the innate immune system. While physiological levels of ROS are crucial for normal cellular functions, excessive or deficient ROS production can lead to a wide range of diseases, including chronic inflammation, fibrosis, neurodegeneration, cancer, and rare immunodeficiencies.
NOX replacement therapy is primarily targeted at patients with inherited NOX2 deficiencies, such as Chronic Granulomatous Disease (CGD). This rare genetic disorder is caused by mutations in genes encoding NOX2 subunits, leading to defective ROS production in phagocytes and resulting in severe, recurrent infections and granuloma formation. Current replacement strategies include:
- Gene therapy using lentiviral or CRISPR platforms to restore NOX2 function.
- mRNA-based approaches aiming to transiently express functional NOX subunits.
- Stem cell transplantation which remains a curative option in severe cases.
These therapies are designed to restore proper immune function by re-establishing controlled ROS production.
NOX inhibitor therapies are developed to suppress overactive NOX enzymes, especially NOX1, NOX2, and NOX4, that contribute to pathological oxidative stress in various chronic diseases. Increased ROS generation has been linked to tissue damage and disease progression in conditions such as:
- Idiopathic pulmonary fibrosis (IPF)
- Primary biliary cholangitis (PBC)
- Alzheimer’s disease and Parkinson’s disease
- Cardiovascular disease
- Solid tumors (e.g., head and neck cancer)

NADPH Oxidase (NOX) Replacement Therapies Emerging Drugs
Setanaxib (GKT831/ GKT-137831): Calliditas Therapeutics
Setanaxib is an orally bioavailable inhibitor of the nicotinamide adenine dinucleotide phosphate (NADPH) oxidases (NOX) 1 and 4, with potential anti-inflammatory, anti-fibrotic and antineoplastic activities. Upon oral administration, setanaxib targets, binds to and inhibits the activity of NOX1 and NOX4. This inhibits NOX1- and NOX4- mediated signal transduction pathways, thereby reducing inflammation and fibrosis. By targeting NOX4-overexpressing cancer-associated fibroblasts (CAFs) in the tumor microenvironment (TME), setanaxib may also inhibit myofibroblastic activation and enhance both the penetration of tumor-infiltrating lymphocytes (TILs) and antitumor T-cell immune responses. The NOX enzymes NOX1 and NOX4 primarily produce reactive oxygen species, which play important roles in cellular signaling processes that regulate cell proliferation, differentiation, and migration, and inflammation and fibrosis.
Setanaxib targets key aspects of primary biliary cholangitis that are not addressed by any currently approved or Phase III therapies. As a novel anti-fibrotic agent, it has the potential to slow disease progression and reduce the need for liver transplantation. What sets Setanaxib apart is its demonstrated positive impact on critical quality-of-life measures, particularly fatigue. Additionally, Setanaxib directly inhibits fibrogenesis in the liver, offering a unique and comprehensive approach to PBC management.
- The US FDA and EMA granted Orphan Drug Designation (ODD) for the Alport syndrome treatment with setanaxib in September and October of 2023, respectively. A Phase II randomized, controlled trial was initiated in November 2023.
- Setanaxib has received ODD from both the FDA and EMA, as well as Fast Track Designation (FTD) from the FDA for PBC treatment.
APX-115: AptaBio
APX-115 is a first-in-class pan-NADPH oxidase (NOX) inhibitor with a Ki value of 0.57–1.08 μM for NOX isozymes. Blocking the activity of NOX with APX-115 inhibited the responses of BMMs to RANKL, including reactive oxygen species (ROS) generation, activation of mitogen-activated protein (MAP) kinases and NF-κB, and OC differentiation. It is being developed as a fundamental treatment to prevent renal and tubular damage caused by oxidative stress and to improve inflammatory cell infiltration in renal tissue. It also serves as a fundamental treatment to prevent damage to glomerular podocytes and tubular epithelial cells caused by oxidative stress.
In October 2023, AptaBio updated that its Acute Kidney Injury Treatment ‘APX-115’ was proven safe in Phase II Clinical Trials by the US FDA.
