Infection of Patients With NDV (Including Strain MTH-68)
The following information is summarized in a table located at the end of this section.
To date, most research into the treatment of human cancer by infection of patients with NDV has been conducted in Hungary.[38,39,41,42] Reviewed in [14,49,50,51] The Hungarian research effort has been led by a single group of investigators who advocate the use of NDV strain MTH-68, which is presumed to be lytic. Findings from these investigations have been published in the form of an anecdotal report that briefly describes results for 3 patients who had metastatic disease; a single case report about a child who had glioblastoma multiforme; a report of a small case series that included 4 individuals with advanced cancer; and a report of a placebo-controlled, phase II clinical trial that included 33 patients in the NDV treatment group and 26 patients in the placebo group. The patients in the phase II trial had various advanced cancers. According to the investigators, MTH-68 treatment was beneficial for the majority of these patients.
The five patients described in the case report and the small case series were reported to have had either a complete remission or a partial remission following NDV therapy.[38,42] Two of the patients in the case series had advanced colorectal cancer, another had melanoma, and the fourth had advanced Hodgkin disease. These five patients were treated with NDV daily for periods of time that ranged from 1 month to 7 years. Inhalation and intravenous injection were the main routes of virus administration. One of the patients with colorectal cancer, however, was treated by means of intracolonic injection (i.e., via a colostomy opening) for 4 weeks. It is important to note that all five patients were treated with conventional therapy before the start of NDV therapy and that four of the five received conventional therapy either concurrently with NDV therapy or after it. Given the small number of patients, the absence of control subjects, and the overlapping treatments, it is difficult to draw conclusions about the effectiveness of NDV therapy from these small studies. Nonetheless, taken as a whole the results of the available NDV studies suggest potential clinical value warranting further study with controlled clinical trials.
