Results

Phase:

Phase 3

This trial looked at the combination of onartuzumab and chemotherapy. It was for people with either:

  • stomach cancer, or
  • cancer in the area where the food pipe (oesophagus) meets the stomach – the gastro oesophageal junction

It was for people whose cancer had spread to another part of the body and who had only small amounts of a protein called HER2. This is called HER2 negative Open a glossary item.

The trial was open for people to join between 2012 and 2014. The team published the results in 2017.

More about this trial

When this trial was done, doctors usually used chemotherapy to treat stomach cancer that had spread to other parts of the body. In this trial, they wanted to see if having onartuzumab as well was useful.

Onartuzumab (MetMab) is a type of targeted treatment called a monoclonal antibody. It targets a receptor Open a glossary item called Met that is found on some cancer cells. 

The people taking part were put into 1 of 2 treatment groups at random:

The main aims of the trial were to find out:

  • if onartuzumab and chemotherapy is better than chemotherapy alone for this group of patients
  • more about the side effects
