THOUSAND OAKS, Calif. (AP) - Shares of drugmaker Amgen Inc. are rising on news its innovative melanoma drug, which uses a virus as a Trojan horse to infiltrate and destroy tumors, shrank far more tumors than a standard treatment in a late-stage test.
The results, released late Tuesday, show there's promise for similar vaccines other companies are developing.
The experimental injected drug made tumors shrink for six months in 16% of study participants. That compares with tumor shrinkage in just 2% of patients in a control group that received a standard treatment.
Amgen also says its interim analysis indicates the drug, dubbed T-VEC for short, may help patients survive longer. More definitive data are expected soon.
Shares of Thousand Oaks, Calif.-based Amgen rose $1.92, or 2.1%, to $94.32 in early afternoon trading.
