I can believe that. I tried to contact them last week and didn't hear a peep.
I'm in the camp that believes if Shire didn't want to continue, they would've made it known by now. As of Dec 2015, SHP622 was still listed on their slate for FA (financials and main website). However, it's still not listed on their clinical trials summary site. No updates on the main clinical trials site either.
Might be a case where big corporate red tape is an issue. Shire now has 60 development programs in their pipeline. They're a big company, but that is still a lot to have to manage.
