55; 95% CI = 1.33-7.97; P < 0.025; learn more Fig. 4B). The results were similar when the analysis was restricted to genotype 1 patients (48 versus 72 weeks: 43.8% versus 19.5% [OR = 3.21; 95% CI 1.228-8.38]; P < 0.025; Fig. 4C,D). None of the 15 HCV genotype 4 patients in groups

A or B had the C/C genotype. Among the HCV genotype 4 infected patients who carried a T allele, three of eight individuals in group A relapsed and one of seven patients in group B relapsed. Among patients with a T allele, extended treatment was associated with lower relapse rates in patients with a baseline HCV RNA level <400,000 IU/mL (18.8% versus 37.5% in patients treated for 48 weeks) and in those with a baseline HCV RNA level ≥400,000 IU/mL (18.8% versus 45.0% in patients treated for 48 weeks) (Fig. 5). Among patients with a C/C genotype and a high baseline HCV RNA level, relapse rates were similar

among those randomized to 48 weeks (6/27, 26%) and 72 weeks of treatment (3/14, 21.4%). Relapse rates and SVR rates were similar in patients who were heterozygous (T/C) or homozygous (T/T) for the T allele (data not shown). The rs12979860 genotype results were available for 48 of 78 (61.5%) patients without an EVR. Only one patient (2.1%) (body mass index 27.5; no cirrhosis, baseline viral load: 66,600 IU/mL) had the C/C genotype, 34 (70.8%) had the T/C genotype, and 13 (27.1%) had the T/T genotype. Four patients (all T/C) were negative at Ixazomib cell line week 24, of whom three achieved an EoT response. Two

of these individuals achieved an SVR and one relapsed. If the results are subjected to an ITT analysis including all patients in whom the rs12979860 genotype was determined, the SVR rates in patients with an RVR assigned to group D were 83.3% (50/60; 95% CI: 71.5-91.7) in those with a homozygous CC genotype and 75.7% (28/37; 95% CI: 58.8-88.2) in those who carried a T allele (T/C or T/T). Among patients with an EVR randomized to 48 and 72 weeks, SVR rates in patients with the homozygous C/C genotype were 70.4% (19/27; 95% CI: 49.8-86.2) and 52.2% (12/23; 95% CI: 30.6-73.2, n.s.), respectively, and SVR rates in patients who carried a T allele (T/C or T/T) were 48.5% (32/66; 95% CI: 36.0-61.1) and 58.2% (39/67; 95% CI: 45.5-70.1; n.s.). In group C, the one patient with a C/C genotype did not achieve an SVR and two of 47 patients who carried a T allele achieved an SVR. The results of this study Branched chain aminotransferase extend what is known about IL28B polymorphisms in patients with chronic hepatitis C by providing insight into the relationship between rs12979860 genotype and relapse, and into the impact of rs12979860 genotype on response-guided therapy for HCV genotype 1 or 4 patients.
