NF-κB Inhibitors – A Promising Future

NF-κB (Nuclear Factor kappa-light-chain-enhancer of activated B cells) is a protein transcription factor that can orchestrate complex biological processes such as cell survival, cytokine production, inflammatory response and cellular responses. NF-κB is also involved in producing the synergistic immune responses.

NF-κB has a robust role in cellular stress, immune responses, inflammation and its mediators playing a significant role in various indications such as cancers, autoimmune diseases, addictions, inflammations, etc. Looking at the functions and targets of NF-κB, it is under a keen inspection for developing the various interventions. NF-κB inhibitors holds a promising place for the further developments.

  • NF-κB is active in tumor cells either due to mutations in genes encoding the NF-κB transcription factors themselves or in genes that control NF-κB activity. Blocking NF-κB can cause tumor cells to stop proliferating, to die, or to become more sensitive to the action of anti-tumor agents. Thus, NF-κB is the subject of much active research among pharmaceutical companies as a target for anti-cancer therapy
  • In cancer, mechanisms that regulate gene expression in response to inflammatory stimuli are altered to the point that a cell ceases to link its survival with the mechanisms that coordinate its phenotype and its function with the rest of the tissue

Currently, various companies are working in this area contributing towards a strong pipeline of about 12+ products. Companies like AnGes MG, MedDay Pharmaceuticals, Reata Pharmaceuticals, Alkermes are the key players amongst the developers of the emerging therapies.

Some of the key emerging therapies are as follows:

  • Bardoxolone Methyl is under development by Reata Pharmaceuticals in the late clinical stage has received Sakigake priority review designation Japan for the treatment of diabetic kidney disease (DKD). Also, the drug has been awarded by Orphan Drug Designation by USFDA for various indications such as Pulmonary Arterial Hypertension, Pancreatic Cancer, and others. These designations point towards the potential chance of the drug to emerge as successful therapy
  • Another drug candidate could be AMG0101 which has completed the phase III trials (ointment) in Japan for Atopic Dermatitis. The same drug is in phase I trial for Low Back Pain due to Disc Degeneration in the United States
  • Alkermes announced its plan to submit a New Drug Application (NDA) for ALKS 8700 for the treatment of RRMS to the U.S. Food and Drug Administration (FDA) in 2018. This brings the drug one step closer to its successful emergence
  • Edasalonexent (CAT-1004) is being evaluated for phase II clinical studies by Catabasis Pharmaceuticals. The potential candidate has been awarded orphan drug, fast track and rare pediatric disease designations for the treatment of Duchenne muscular dystrophy (DMD) The U.S. Food and Drug Administration (FDA) and orphan medicinal product designation by the European Commission (EC). This signifies the promising future CAT-1004

The pipeline is robust with the drugs in all the clinical stages signifying NF-κB Inhibitor development as the emerging potential area of therapeutic research.
