Combined Opioidergic and Beta-Adrenergic Drugs for Cancer and Immune Diseases


Invention Summary:

One of the major cancer therapy approaches that is being heavily investigated is immunotherapy. Immunotherapy involves modulating the cancer patient’s own immune system to identify tumors and cancer cells as foreign to their body. Currently, the major pathways being studied involve regulating the function of T-lymphocytes via CTLA-4 and PD-1 as these cells’ primary function is to distinguish host cells from foreign cells. However, immunotherapies involving drugs that influence other cellular pathways are limited in the market.

Rutgers researchers have identified that DPDPE, naltrexone, and propranolol can be combined with PD-1-based immunotherapies to improve cancer treatments. The researchers show that cancer cell lines from breast and colon cancers treated with this novel cocktail decreases cells’ proliferation rate and increases their apoptotic rate. The addition of the three drugs increases immune responses, synergizing with the effect of the traditional, PD-1 antibody-based treatment. In addition, xenograft models in rats validate the cell lines results with decreased tumor sizes in rats treated with the combination of drugs.  


  • DPDPE, naltrexone, and propranolol are drugs that are approved by FDA
  • Increased efficacy of already-used cancer treatment
  • General treatment for boosting innate immune system’s response

Market Applications:

  • Adjuvant for treatment of broad cancer types
  • Immunomodulation for improving response to treatment of other diseases
