Novel Inhibitors of Interleukin-6 for Kaposi Sarcoma Therapy

Posted Oct 27 2009 5:00pm

Description of Invention:
The cancer therapy market is forecast to reach $40.9 billion by 2012. With immunosuppressant drugs set for phenomenal growth over the next six years, revenues could reach $26.2 billion by 2014. One market for which there is a significant need for new therapies is cancers induced by Kaposi Sarcoma-associated Herpesvirus (KSHV).

Researchers at the National Cancer Institute have identified novel nucleic acid sequences that act through a unique mechanism to inhibit the expression of interleukin-6 that occurs in cancerous cells transformed by KSHV infection and which promotes cancer cell proliferation. The researchers have also identified a key protein involved in the mechanism which could be inhibited using antibodies.

These inhibitors are likely to be accepted in the marketplace because their unique specificity in mechanism of action gives them a distinct advantage over the mechanisms of other existing therapies.

  • Therapies for KSHV-induced cancers (Kaposi sarcoma (KS), primary effusion lymphoma (PEL) and multicentric Castleman disease (MCD)
  • Therapies for KSHV infection
  • Therapies for interleukin-6 associated inflammatory diseases
  • Immunosuppression of interleukin-6

  • Utilizes available small-molecule and antibody technologies
  • Targets a key pathway in interleukin-6 production
  • Specificity of mechanism of action may reduce/limit potential side-effects
