  • Patent number: 10744171
    Abstract: Human clinical use of a chimeric poliovirus construct has demonstrated excellent anti-tumor effect. Sequential treatment with the virus construct followed by chemotherapy drugs increases the anti-tumor effect. Tumors of different types are susceptible to the combination treatment, including but not limited to melanoma, glioblastoma, renal cell carcinoma, prostate cancer, breast cancer, lung cancer, medulloblastoma, and colorectal cancer.

  • Publication number: 20190343904
    Abstract: Human clinical use of a chimeric poliovirus construct has demonstrated excellent anti-tumor effect. The mechanism of action is believed to involve both viral oncolysis as well as immune recruitment, both of which lead to necrosis in the area of the tumor. No adverse effects have been observed.

  • Publication number: 20180236054
    Abstract: Pre-conditioning a vaccine site with a potent recall antigen such as tetanus/diphtheria (Td) toxoid can significantly improve the lymph node homing and efficacy of tumor antigen-specific DC vaccines. Patients given Td had enhanced DC migration bilaterally and significantly improved survival. In mice, Td pre-conditioning also enhanced bilateral DC migration and suppressed tumor growth in a manner dependent on the chemokines CCL3 and CCL21 and Td-activated CD4+ T cells. Interference with any component of this axis markedly reduced Td-mediated DC migration and antitumor responses. Our clinical studies and corroborating investigations in mice suggest that pre-conditioning with a potent recall antigen represents a viable strategy to increase DC homing to lymph nodes and improve antitumor immunotherapy.

  • Publication number: 20180215789
    Abstract: The concurrent administration of chemotherapy and immunotherapy has been considered a contraindication because of the concern that the induced lymphopenia would ablate therapeutic efficacy of immunotherapy. Temozolomide has been shown to be an effective chemotherapeutic for patients with malignant gliomas and to deprive patients with glioblastoma (GBM) patients of this agent in order to treat with immunotherapy is controversial. Despite conventional dogma, we demonstrate that both chemotherapy and immunotherapy can be delivered concurrently without negating the effects of immunotherapy. In fact, the temozolomide induced lymphopenia may actually be synergistic with a peptide vaccine.

  • Publication number: 20150307614
    Abstract: Cancers and other diseases can be treated with two or three types of agents: an agent which induces lymphodepletion or lymphopenia; an inhibitory antibody to a surface marker on Treg cells; and optionally a specific antigen. This combination may lead to enhanced immune responses despite lymphodepletion or lymphopenia.
