Summary of the safety profile in adults The safety assessment of Ledipasvir/Sofosbuvir Gilead was mainly based on pooled Phase 3 clinical studies, without a control, in 1952 patients who received Ledipasvir/Sofosbuvir Gilead for 8, 12 or 24 weeks, including 872 patients who received Ledipasvir/Sofosbuvir Gilead in combination with ribavirin.
The proportion of patients who permanently discontinued treatment due to adverse events was 0%, < 1% and 1% for patients receiving ledipasvir/sofosbuvir for 8, 12 and 24 weeks, respectively; and < 1%, 0%, and 2% for patients receiving ledipasvir/sofosbuvir + ribavirin combination therapy for 8, 12 and 24 weeks, respectively.
In clinical studies, fatigue and headache were more common in patients treated with ledipasvir/sofosbuvir compared to placebo. When ledipasvir/sofosbuvir was studied with ribavirin, the most frequent adverse drug reactions to ledipasvir/sofosbuvir + ribavirin combination therapy were consistent with the known safety profile of ribavirin, without increasing the frequency or severity of the expected adverse drug reactions.
Tabulated list of adverse events The following adverse drug reactions have been identified with Ledipasvir/Sofosbuvir Gilead (Table 7). The adverse reactions are listed below by body system organ class and frequency. Frequencies are defined as follows: very common (≥ 1/10), common (≥ 1/100 to < 1/10), uncommon (≥ 1/1,000 to < 1/100), rare (≥ 1/10,000 to < 1/1,000) or very rare (< 1/10,000).

Adverse drug reactions identified with Ledipasvir/Sofosbuvir Gilead Frequency Adverse drug reaction Nervous system disorders: Very common headache Skin and subcutaneous tissue disorders: Common rash Not known angioedema General disorders: Very common fatigue Adults with decompensated cirrhosis and/or who are awaiting liver transplant or post-liver transplant The safety profile of ledipasvir/sofosbuvir with ribavirin for 12 or 24 weeks in adults with decompensated liver disease and/or those post-liver transplant was assessed in two open-label studies (SOLAR-1 and SOLAR-2).
No new adverse drug reactions were detected among patients with decompensated cirrhosis and/or who were post-liver transplant and who received ledipasvir/sofosbuvir with ribavirin. 1 for details of this study). 5 g/dL during treatment were experienced by 39% and 13% of patients treated with ledipasvir/sofosbuvir with ribavirin, respectively.
Ribavirin was discontinued in 15% of the patients. 7% of liver transplant recipients had a modification of their immunosuppressive agents. Patients with renal impairment Ledipasvir/sofosbuvir was administered for 12 weeks to 18 patients with genotype 1 CHC and severe renal impairment in an open-label study (Study 0154).
In this limited clinical safety data set, the rate of adverse events was not clearly elevated from what is expected in patients with severe renal impairment. The safety of Ledipasvir/Sofosbuvir Gilead has been evaluated in a 12-week non- controlled study including 95 patients with ESRD requiring dialysis (Study 4063).
In this setting, exposure of sofosbuvir metabolite GS- 331007 is 20-fold increased, exceeding levels where adverse reactions have been observed in preclinical trials. In this limited clinical safety data set, the rate of adverse events and deaths was not clearly elevated from what is expected in ESRD patients.
Paediatric population The safety and efficacy of Ledipasvir/Sofosbuvir Gilead in paediatric patients aged 3 years and above are based on data from a Phase 2, open-label clinical study (Study 1116) that enrolled 226 patients who were treated with ledipasvir/sofosbuvir for 12 or 24 weeks or ledipasvir/sofosbuvir plus ribavirin for 24 weeks.
The adverse reactions observed were consistent with those observed in clinical studies of ledipasvir/sofosbuvir in adults (see Table 7). 5).
