DCV/ASV 036 study summary

� 99% SVR24 in Asia patients without baseline NS5A RAVs from 036 study– majority patients with characteristic of traditional difficult-to-treat:

high viral load, IL28B non-CC, and cirrhosis.

� No treatment-related serious AEs or grade 4 laboratory

21

� No treatment-related serious AEs or grade 4 laboratory abnormalities

� Infrequent (1%) discontinuations due to AEs

� DCV+ASV is a highly efficacious and well-tolerated treatment for patients with HCV GT-1b infection, particularly those without baseline NS5A RAVs

Conclusions from Pooled-analyses data

� The all-oral, RBV-free regimen of DCV + ASV was highly efficacious for treatment of GT-1b without baseline NS5A-L31 or NS5A-Y93H resistance-associated polymorphisms– SVR12 rates of up to 100% across subgroups including the elderly (>

65 years of age) and patients with cirrhosis– Pre-therapy screening for NS5A polymorphisms at L31 and Y93H may

be beneficial

28

be beneficial

� These findings are consistent with earlier data in Japanese and non-Asian patients and in a smaller pooled group of Korean and Taiwanese patients1

Initial treatment, Daclatasvir + asunaprevir 24 weeks

(ombitasvir/ paritaprevir/ ritonavir 12 weeks)Re-treatment

41*MLHW: Ministry of Labor Health and Welfare

� For dialysis patients with HCV infection, daclatasvir + asunaprevir therapy is the first-line

treatment at present based on actual clinical evidence.

� Prior to therapy, the absence of resistance mutations in the NS5A region (Y93 and L31) should be

confirmed.

� Dialysis patients are often on multiple medications; thus, it is important to review drug

interactions beforehand.

� In dialysis patients, serum ALT levels are reported to be lower than usual.

� If liver injury occurred during therapy, the patient should be carefully monitored, and a dose

reduction or discontinuation should be considered.

� Between August 2015 and March 2016, a total of 161 patients with chronic hepatitis C (CHC) who finished treatment with DCV+ASV at Severance hospital were analyzed.

Methods

� The patients received DCV (60mg once daily) plus ASV (100mg twice daily) for 24 weeks.

� End of Treatment Response (ETR) and Sustained Virological Response at post-treatment week 12 (SVR12) and safety outcomes were evaluated.
