I am going to try to post the results of the SVR chart here:
Treatment-Naive Patients
ABT -450/r + ABT-267 + ABT-333 + RBV for 8 Wks
SVR24 88%
Breakthrough None
Relapse 10
ABT-450/r + ABT-333 + RBV for 12 Wks
SVR24 83%
Breakthrough 1
Relapse 4
ABT-450/r + ABT-267 + RBV for 12 Wks
SVR24 89%
Breakthrough 1
Relapse 8
ABT-450/r + ABT-267 + ABT-333 for 12 Wks
SVR24 87%
Breakthrough 1
Relapse 5
ABT-450/r + ABT-267 + ABT-333 + RBV for 12 Wks
SVR24 96%
Breakthrough 0
Relapse 1
ABT-450/r + ABT-267 + ABT-333 + RBV for 24 Wks
SVR24 90%
Breakthrough 0
Relapse 2
The number of people in each group was about 80 people except for the following group which contained 41 people:
ABT-450/r + ABT-333 + RBV for 12 Wks
so anyone knows difference on svr between riba and without riba arms?
AVIATOR: ABT-450/Ritonavir, ABT-267 and/or ABT-333, and RBV Achieves SVR24 Rates ≥ 90% in Treatment-Naive Patients and Previous Null Responders With Genotype 1 HCV
Source: 2013 Annual Meeting of the European Association for the Study of the Liver*
Capsule Summary Date posted: 4/26/2013
Updated interim analysis of AVIATOR (M11-652): ongoing multicenter, randomized, open-label phase IIb study[1]
Or...... just go to this site and it will tell you about the trials and the results.

Summary of Key Conclusions
Treatment with 4-drug regimen of ABT-450/ritonavir, ABT-267, ABT-333, and ribavirin (RBV) for 12 or 24 weeks achieved very high sustained virologic response rates at 24 weeks posttreatment (SVR24) in noncirrhotic patients infected with genotype 1 HCV
SVR24 rates 90% to 96% in treatment-naive patients, 93% to 95% in previous null responders
SVR24 rates ≥ 89% in several difficult-to-treat populations, including those with HCV genotype 1a infection and non-CC IL28B genotype
Virologic breakthrough and relapse infrequent in all groups
4-drug regimen relatively well tolerated
Treatment-related adverse events typically mild in severity
50,000 IU/mL
Treatment history
Treatment naive: no previous HCV therapy
Null responder: failure to achieve ≥ 2 log10 IU/mL decrease in HCV RNA following ≥ 12 weeks of treatment with peginterferon/RBV
Exclusion criteria
Evidence of cirrhosis
HIV or HBV coinfection
Baseline Characteristics
Some imbalances in baseline characteristics across arms
2 arms had lower proportions of males compared with other arms (43% to 44% vs 56% to 63%)
IL28B CC genotype markedly lower among null responders vs treatment-naive patients (2% to 4% vs 27% to 34%), as expected
Main Findings
SVR24 rates ≥ 90% in both treatment-naive patients and previous null responders treated with 12 or 24 weeks of ABT-450/ritonavir, ABT-267, ABT-333, and ribavirin
SVR12 rate among treatment-naive patients highest (99%) with 4-drug regimen for 12 weeks
SVR12 rate among previous null responders highest (98%) with 4-drug regimen for 24 weeks
Only 3 patients had virologic relapse between 12 and 24 weeks posttreatment
8 patients with SVR12 data did not return for > 24 weeks and counted as virologic failures in SVR24 assessment
Among 247 patients treated with 12 or 24 weeks of ABT-450/ritonavir, ABT-267, ABT-333, and RBV, therapy relatively well tolerated
6 patients (2.4%) discontinued study therapy for adverse events
Events considered treatment related in 4 patients (1 event each of cholestatic hepatitis, feeling jittery, homicidal ideation, and decreased creatinine clearance)
4 patients (1.6%) reported serious adverse events
Events considered potentially treatment related in 1 patient (arthralgia)
Majority of adverse events mild in severity
No grade 4 laboratory abnormalities reported and grade 3 events uncommon, except for transient increases in bilirubin that resolved during continued therapy
I am having trouble posting the link to the capsule summary because it takes you to my logged in page. But you can register for Clinical Care Options (it is free) and then you can view all of their material, information, data, articles, etc. Type in Clinical Care Options and register.
3 Words...........JUMP ON IT!!!! Just google ABT-450. Genotype 1B's are doing the best also.
