Background and Rationale: Most patients with chronic hepatitis C show virological response to telaprevir-based triple therapy, and achieve an end-of-treatment response (ETR). However, some patients showing ETR develop virological relapse. This study was carried out to evaluate factors associated with relapse after triple therapy. Materials and Methods: A prospective, multicentric study was conducted in chronic hepatitis C patients who received telaprevir-based triple therapy. We evaluated independent variables such as age, with or without cirrhosis, prior treatment response to interferon (IFN) therapy, IL28B genotype, core amino acid (aa) 70 mutation, drug adherence, white blood cell counts, hemoglobin level, and serum low-density lipoprotein (LDL) cholesterol level. The characteristics of the patients who relapsed after achieving ETR were compared with those who did not. Results: Among 168 patients, 157 patients achieved ETR (93.5%) and 11 discontinued. Of these 157 patients, relapse occurred in 21 patients (13.4%). Nineteen patients (90.5%) of 21 relapsed patients had the IL28B non-TT genotype (P = 1.79 × 10 -9 ). Multivariate analysis identified core amino acid 70 [P = 0.018, crude odds ratio (OR): 6.927] and the IL28B genotype (P = 3.758 × 10 -5 , crude OR: 39.311) as significantly independent factors that influenced the relapse-related variables. Among the 49 patients with the IL28B non-TT, 18 patients had core aa70 mutation and 31 patients had core aa70 wild-type. In addition, 66.7% (12/18) of those with core aa70 mutation and 22.6% (7/31) of those with core aa70 wild-type developed relapse (P = 0.005). Discussion: Core aa70 mutation and the IL28B non-TT genotype were identified as independent factors that influenced relapse after achievement of ETR for telaprevir-based triple therapy.
