Newcastle disease virus administration
A mammalian subject having a tumor is treated by a method comprising administering an effective amount of a Newcastle disease virus, wherein the virus is administered to the subject in one or more cycles; and at least one cycle comprises administering sequentially one or more initial doses of from 1.8×10 10 PFU to 4.8×10 10 PFU of the virus per square meter of patient surface area followed by administering one or more subsequent doses of from 2.4×10 10 PFU to 1.2×10 11 PFU of the virus per square meter of patient surface area.
1 . A method for treating a mammalian subject having a tumor, comprising administering to the subject an amount of a Newcastle disease virus effective to treat the subject, wherein
the virus is administered to the subject in one or more cycles;
at least one cycle comprises administering sequentially one or more initial doses of from 1.8×10 10 PFU to 4.8×10 10 PFU of the virus per square meter of patient surface area followed by administering one or more subsequent doses of from 2.4×10 10 PFU to 1.2×10 11 PFU of the virus per square meter of patient surface area.
2 . The method of claim 1 , wherein the one or more initial doses are desensitization doses and the subsequent doses are escalated doses, the amount of the virus in each escalated dose being higher than the amount of virus in each desensitization dose.
3 . The method of claim 2 , wherein the one or more desensitization doses are about 2.4×10 10 PFU per square meter of patient surface area, and the one or more escalated doses are about 4.8×10 10 PFU per square meter of patient surface area.
4 . The method of claim 1 , wherein the one or more initial doses are from 2.4×10 10 PFU to 4.8×10 10 PFU of the virus per square meter of patient surface area.
5 . The method of claim 1 , wherein the one or more subsequent doses are from 4.8×10 10 PFU to 1.2×10 11 PFU of the virus per square meter of patient surface area
6 . The method of claim 1 , wherein the virus is a mesogenic strain of Newcastle Disease Virus.
7 . The method of claim 1 , wherein the virus is administered systemically.
8 . The method of claim 7 , wherein the virus is administered intravenously.
9 . The method of claim 8 , wherein the virus administered is a mesogenic strain of Newcastle Disease Virus.
10 . The method of claim 1 , wherein the virus dose is administered over an administration time period of up to 24 hours; and the dose is administered at a rate of up to 7.0×10 8 PFU per square meter of patient surface area in any ten minute sampling time period within the administration time period.
11 . The method of claim 10 , wherein the rate is up to 2.0×10 8 PFU per square meter of patient surface area in any ten minute sampling time period within the administration time period.
12 . The method of claim 10 , wherein the administration time period is at least 1 hour.
13 . The method of claim 12 , wherein the administration time period is at least 3 hours.
14 . The method of claim 1 , wherein the subject is a human subject.
15 . The method of claim 1 , wherein the subject is a non-human mammal.
16 . The method of claim 1 , wherein the size of the tumor decreases after administration of the virus.
17 . The method of claim 1 , wherein the tumor is selected from the group consisting of rectal cancer, pelvic cancer, colon cancer, carcinoid, melanoma, ovarian cancer, sarcoma, cancer of the gastro-esophageal junction, gastric cancer, esophageal cancer, liver cancer, and cervical cancer.
18 . The method of claim 8 , further comprising administering fluids intravenously to the subject after administration of the first of the one or more initial doses.
19 . The method of claim 18 , wherein the subject is a human and at least 4 liters of IV fluids are administered in the 24 hours following the first initial dose.
