6 ADVERSE REACTIONS Most common adverse reactions (incidence ≥ 7%) are nasopharyngitis and abdominal pain. gov/medwatch. 1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The safety of ANDEMBRY reflects the exposure in a total of 164 adult and pediatric patients aged 12 years and older with hereditary angioedema (HAE) from a placebo-controlled study, VANGUARD [see Clinical Studies (14) ] , and an open-label clinical study.

Among the 164 patients who received at least one dose of ANDEMBRY 200 mg subcutaneously, 153 (93%) patients were exposed for at least one year. 6 years. The safety data below is based on the 6-month placebo-controlled study (VANGUARD), in which ANDEMBRY 400 mg was administered subcutaneously as a loading dose followed by 200 mg (N=39) every month in patients with HAE.

Demographics of the patients in this study are summarized in Clinical Studies [see Clinical Studies (14) ]. The safety of ANDEMBRY was similar across all subgroups of patients, including analysis by age, sex and geographic region. Table 1 provides the most common adverse reactions with ANDEMBRY with incidence ≥7% and more common than placebo.
