  • Patent number: 7960364
    Abstract: Covalently reactive antigen analogs are disclosed herein. The antigens of the invention may be used to stimulate production of catalytic antibodies specific for predetermined antigens associated with particular medical disorders. The antigen analogs may also be used to permanently inactivate endogenously produced catalytic antibodies produced in certain autoimmune diseases as well as in certain lymphoproliferative disorders. Also provided are methods for modulating the efficacy of nucleic acid based therapeutics.

  • Patent number: 7795232
    Abstract: The present invention is directed to the use of bcl-2 antisense oligomers to treat and prevent bcl-2 related disorders. These disorders include cancers, tumors, carcinomas and cell-proliferative related disorders. In one embodiment of the invention, a bcl-2 antisense oligomer is administered at high doses. The present invention is also directed to a method of preventing or treating a bcl-2 related disorder, in particular cancer, comprising administering a bcl-2 antisense oligomer for short periods of time. The present invention is further drawn to the use of bcl-2 antisense oligomers to increase the sensitivity of a subject to cancer therapeutics. The present invention also relates to pharmaceutical compositions comprising one or more bcl-2 antisense oligomers, which may comprise one or more cancer therapeutic agents.

  • Patent number: 7060690
    Abstract: The present invention is directed to hybrid oligomers comprising a cyclic AMP response element (CRE) sequence and a sequence that hybridizes to a bcl-2 pre-mRNA or mRNA, and pharmaceutical compositions comprising such hybrids. The present invention is also directed to the use of CRE decoy oligomers, comprising a CRE consensus sequence, and bcl-2 antisense oligomers in combination therapies, and the use of bcl-2/CRE hybrid oligomers, to treat or prevent cell-proliferative related disorders, including hyperplasias, cancers, tumors and carcinomas. In one embodiment, the invention relates to therapeutic protocols comprising the administration of a CRE decoy oligomer and a bcl-2 antisense oligomer for the treatment of cell-proliferative related disorders. In another embodiment, the invention relates to therapeutic protocols comprising the administration of a bcl-2 antisense/CRE decoy (bcl-2/CRE) hybrid oligomer for the treatment of cell-proliferative related disorders.
