Abstract
Human clinical use of a chimeric poliovirus construct has demonstrated excellent anti-tumor effect. Combination with immune checkpoint inhibitors increases the anti-tumor effect. Tumors of different types are susceptible to the combination treatment, including but not limited to melanoma, glioglastoma, renal cell carcinoma, prostate cancer, breast cancer, lung cancer, medulloblastoma, and colorectal cancer.
Claims35
A method of treating a tumor in a patient, comprising:
- administering to the patient a PVSRIPO chimeric poliovirus construct comprising a Sabin type I strain of poliovirus with a human rhinovirus 2 (HRV2) internal ribosome entry site (IRES) in said poliovirus' 5′ untranslated region between said poliovirus' cloverleaf and said poliovirus' open reading frame;
- and
- administering an anti-PD-1 antibody, whereby the patient is treated.
