The Abbvie regimen contains Paritaprevir, which is a
PI, so those who have failed in the past with a
PI (Telaprevir, Boceprevir, Olysio) should not treat with the Abbvie drugs.
Treating with Harvoni is the AASLD recommended way to go.
The AASLD guidelines for those who failed with a PI are copied and pasted below. Go towards the bottom and you will see that the AASLD does NOT recommend the Abbvie drug regimen for those who failed with another PI.
