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.
Claims31
A method of treating a human harboring a solid tumor that expresses NECL5 (nectin-like protein 5), said method comprising the steps of:
- administering directly to the tumor in the human a 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, wherein the tumor is not a glioblastoma.
A method of treating a human harboring a solid tumor which expresses NECL5 (nectin-like protein 5), said method comprising the steps of:
- testing a solid tumor to ascertain that it expresses NECL5;
- and
- administering directly to the tumor in the human a 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, wherein the tumor is not a glioblastoma.
A method of delivering a clinical pharmaceutical preparation to a solid tumor in a human, comprising:
- administering via convection enhanced infusion through a single intratumoral catheter, a dose of a poliovirus construct within 6.5 hours, wherein said poliovirus construct is in a clinical pharmaceutical preparation 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, wherein the tumor is not a glioblastoma;
- and gadolinium.
