Cancer-killing therapy using common cold virus may save patients with inoperable tumors
by Chris Melore
NEW YORK ? When cancer patients have an inoperable tumor, treatment options can be extremely limited ? if not impossible. New research is offering some hope for patients batting such devastating circumstances. Doctors at NYU Langone Health say a new virus therapy is offering hope to patients without a surgical option. In clinical trials, a common cold virus combined with an immunotherapy drug infects and kills cancer cells.
Study authors say this is one of the first experiments to prove oncolytic viruses can safely boost existing cancer therapies. Currently, immunotherapies which help the human immune system kill cancer cells only successfully shrink tumors in a third of patients.
The new virus combo injects patients with an experimental drug created using a coxsackievirus, V937. Patients also receive pembrolizumab, an immunotherapy drug also known as pembro or Keytruda. Thirty-six men and women participated in the trial, receiving the therapy every few weeks for a minimum of two weeks.
The combined treatments successfully shrank melanoma tumors in 47 percent of these patients. Moreover, eight of the patients taking both drugs went into complete cancer remission with no signs of their skin cancer.
?Our initial study results are very promising and show that this oncolytic virus injection, a modified coxsackievirus, when combined with existing immunotherapy is not only safe but has the potential to work better against melanoma than immunotherapy alone,? says study senior investigator and medical oncologist Dr. Janice Mehnert, in a media release.
Serious side-effects remain
Study authors note the experimental treatment does have some noticeable side-effects, both mild and severe. Most of the participants developed mild reactions, such as a rash or fatigue. However, 13 patients (36%) experienced serious immune reactions in the liver, stomach, or lungs. Researchers say these reactions also occur in cancer patients taking pembrolizumab alone...
