This technology offers the potential of new and novel cancer treatments based on various inhibitors of protein tyrosine kinases
Background: Genes that regulate extracellular growth, differentiation, and developmental signals are commonly mutated in cancers. Protein tyrosine kinases (PTKs) mediate the reversible process of tyrosine phosphorylation, providing the signals that activate or block signal transduction pathways that govern cell survival. As such, PTKs comprise the largest group of dominant oncogenes. In recent years, there have been increased efforts to discover genes critical to cancer signaling pathways that, when inhibited, would provide specific anti-cancer therapies. While a number of inhibitors have been reported, it is not clear whether they possess the appropriate pharmacological properties to be therapeutically useful. Therefore, there is a continued need for small molecule inhibitors to provide effective inhibition. Such compounds would be extremely useful in treating disease states where inhibition could play a role.
Technology Overview: This technology is a method of treating cancers, for example breast cancers, based on PTK inhibition. This can include an inhibitor of a tyrosine kinase. This inhibitor can be ibrutinib (PCI-32765), AVL-292, or CGI-1746. The inhibitors can also include EGFR inhibitors, such as lapatinib, gefitinib, erlotinib, cetuximab, panitumumab, or vandetanib. A variety of therapeutics can be formulated through different combinations of these inhibitors. These therapeutics can be administered to the patient sequentially, or in some instances simultaneously. Research indicates that in some cases, these inhibitors result in reduced proliferation of at least some cancer cells within the patient, offering the possibility for the development of new and novel cancer treatments.
