ABBV/ENTA—HIV co-infection part is recommended, while cirrhosis is strongly suggested, see the wording difference there, thus ABBV/ENTA to include cirrhosis in original NDA, but not HIV co-infection.
The staging of TURQUOISE-1 and TURQUOISE-2 was more of a business decision than a regulatory decision, IMO.
It’s very important for ABBV/ENTA to have GT1 cirrhotic patients on-label from the get-go, while promoting the GT1 regimen for HCV/HIV co-infected patients can wait. The initial label will not explicitly exclude HIV patients, but rather will say that the drug cocktail has not (yet) been tested in HIV patients.
Has GILD guided on their planned submission in gen-1 yet? I ask because clinicaltrials.gov still has their cirrhotic study listed as enrolling. It also has a 24 week arm. so, it does appear to be behind their non-cirrhotic study even though both are estimated to be completed more or less the same time (latter part of 2014)
