Incyte Corporation (NASDAQ: INCY), a
biopharmaceutical company that focuses on developing medications for the treatment of cancer, announced
Friday a disappointing update to a phase 3 trial.
What Happened
Incyte said its experimental therapy called epacadostat failed in a phase 3 trial called ECHO-301 to improve the efficacy of
Merck & Co., Inc. (NYSE: MRK)'s Keytruda when the two
therapies were combined to treat patients suffering from melanoma.
The purpose of the study was to demonstrate that Incyte's therapy, which blocks the enzyme IDO, could make existing cancer treatments like Keytruda more effective. Unfortunately, the study found that the
combination of the two therapies failed to delay the growth of cancer in patients and those who received a placebo exhibited
similar survival rates versus those who received the treatment.
Why It's Important
The disappointing results has "far-ranging ramifications" for Incyte and raise "serious doubts" about the future for IDO
inhibitors, Stat News' Adam Feuerstein said. It also marks
a "big setback" for patients suffering from melanoma.
What's Next
The disappointing trial could also "ripple across" the entire cancer immunotherapy market and overall biotech sector, Feuerstein
said. Nevertheless, Incyte Chief Medical Officer Steven Stein said the company remains dedicated to "transforming the treatment of
cancer and will continue to explore how IDO1 inhibition and other novel mechanisms can potentially improve outcomes for patients in
need."
At time of publication, Incyte was trading down 22 percent at $64.70. Merck was down about 1.1 percent.
