ImmunoGen Inc said the gastric cancer drug it is developing with Roche Holding AG did not meet the main goal in a large study.

ImmunoGen entered into a royalty purchase agreement with Roche for Kadcyla this year.

Kadcyla, approved in 2013 for the treatment of late-stage breast cancer, was being tested as a second-line treatment for gastric cancer in the late-stage study.

The drug raked in revenue of about $580.3 million this year.

Kadcyla carries a cell-killing payload directly into cancer cells, causing fewer cases of common chemotherapy side effects like hair loss.

Detailed findings from the trial will be reported at a future medical conference, the company said.
