Exactly my point. If you KNOW about the trial and KNOW the keywords SUNRISE and BAVITUXIMAB then you'll eventually find them all.
No see how long your are at it since you started posting your first German finds.
Now do the search WITHOUT your Browsers History and do not use the SUNRISE and BAVITUXIMAB because actually you do not know these words. The only thing you know as a patient is that you have been diagnosed with Non Small Cell Lung Cancer (in the language of your country of course) because that is what your Doctor will have told you.
Then try to see if you'd find all those links that easy.
