6 Adverse Reactions

6.1 Clinical Trials Experience

Newly added information:

Adverse Reactions in Pediatric Subjects 3 Years of Age and Older

In a 5-year follow-up study, 88 of the 106 subjects from the Phase 2 open-label clinical trial (Study 1112) were followed for a median (Q1, Q3) duration of 239 (179, 244) weeks. No notable effects on growth as assessed by changes from baseline through end of study were observed for height, weight, BMI percentiles, and Z-scores for any age group. No notable effects were observed on the development of secondary sexual characteristics of subjects as assessed by changes from baseline through end of study in Tanner pubertal stages [see Use in Specific Populations (8.4)].

8 Use in Specific Populations

8.4 Pediatric Use

Newly added information:

In a 5-year follow-up study, the long-term effects of SOVALDI on pediatric growth were assessed in 88 pediatric subjects 3 years of age and older treated with SOVALDI in Study 1112. No notable effects on growth from baseline through end of study were observed [see Adverse Reactions (6.1)]. All subjects who had achieved SVR12 maintained SVR through end of study.

7 Drug Interactions

7.1 Potentially Significant Drug Interactions

(additions underlined)

Clearance of HCV infection with direct acting antivirals may lead to changes in hepatic function, which may impact the safe and effective use of concomitant medications. For example, altered blood glucose control resulting in serious symptomatic hypoglycemia has been reported in diabetic patients in postmarketing case reports and published epidemiological studies. Management of hypoglycemia in these cases required either discontinuation or dose modification of concomitant medications used for diabetes treatment.

Frequent monitoring of relevant laboratory parameters (e.g. International Normalized Ratio [INR] in patients taking warfarin, blood glucose levels in diabetic patients) or drug concentrations of concomitant medications such as cytochrome P450 substrates with a narrow therapeutic index (e.g. certain immunosuppressants) is recommended to ensure safe and effective use. Dose adjustments of concomitant medications may be necessary.


Information on potential drug interactions with SOVALDI is summarized in Table 7. The table is not all-inclusive.
