[Updated for release of top-line data from SAPHIRE-1.]

ABBV/ENTA have 9 global phase-3 trials testing an all-oral regimen in HCV genotype-1a/1b : 6 trials that comprise the initial NDA/MAA submissions in 2Q14, and 3 trials for subsequent use. Full details of the 6 trials comprising the initial NDA/MAA will be presented at the EASL conference in Apr 2014.

All 9 of these global phase-3 trials include the 3-DAA combination of the protease inhibitor, ABT-450/r (licensed by ABBV from ENTA); the NS5A inhibitor, ABT-267 (from ABBV’s pipeline); and the non-nucleoside polymerase inhibitor, ABT-333 (from ABBV’s pipeline). Some of these trials also include ribavirin in one or both trial arms.

(ABBV/ENTA are testing the 2-DAA regimen of ABT-450/r + ABT-267 in a phase-3 trial for genotype-1b patients in Japan [#msg-91870291] and in various phase-2 trials globally.)

Six phase-3 trials comprising initial NDA/MAA submissions:

SAPPHIRE-1—treatment-naïve GT1a/1b w/o cirrhosis; ABT-450/r + ABT-267 + ABT-333 + ribavirin for 12w vs. identical regimen delayed by 12 weeks of placebo use;631 patients (68% GT1a, 32% GT1b); top-line results were released on 11/18/13 and discussed in #msg-94169219:

PEARL-2—treatment-experienced GT1b w/o cirrhosis; ABT-450/r + ABT-267 + ABT-333 ± ribavirin for 12w; 210 patients; expected completion Mar 2014:
http://www.clinicaltrials.gov/ct2/show/NCT01674725

http://www.clinicaltrials.gov/ct2/show/NCT01767116

PEARL-4—treatment-naïve GT1a w/o cirrhosis; ABT-450/r + ABT-267 + ABT-333±ribavirin for 12w; 300 patients; expected completion Dec 2013:
http://www.clinicaltrials.gov/ct2/show/NCT01833533

TURQUOISE-2—DAA-naïve GT1a/1b with cirrhosis; ABT-450/r + ABT-267 + ABT333 + ribavirin for 12w vs. identical regimen for 24w; 380 patients; expected completion Jan 2014:
http://www.clinicaltrials.gov/ct2/show/NCT01704755

Three phase-3 trials not part of initial NDA/MAA submissions:

TURQUOISE-1—DAA-naïve GT1a/1b with HIV co-infection; ABT-450/r + ABT-267 + ABT333 + ribavirin for 12w vs. identical regimen for 24w; 300 patients; expected completion Dec 2014:
http://clinicaltrials.gov/ct2/show/NCT01939197

MALACHITE-1—5-arm trial including 3 DAA arms and 2 control arms—treatment-naïve GT1a/1b; ABT-450/r + ABT-267 + ABT-333 + ribavirin for 12w vs. Incivek + peg-IFN + ribavirin for 12w plus an additional 12w or 36w of peg-IFN/ribavirin on a response-guided basis; separate DAA and control arms for GT1a and GT1b; additional DAA arm for GT1b without ribavirin; 314 patients; expected completion Jul 2015:
http://www.clinicaltrials.gov/ct2/show/NCT01854697
(Note: This is essentially a phase-4 trial.)

MALACHITE-2—treatment-experienced GT1a/1b; ABT-450/r + ABT-267 + ABT-333 + ribavirin for 12w: vs. Incivek + peg-IFN + ribavirin for 12w plus an additional 12w or 36w of peg-IFN/ribavirin on a response-guided basis; 150 patients; expected completion Jul 2015:
