SIDE EFFECTS
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 data described below reflect exposure to 589 patients, of whom 518 received a 2 g dose of SOLOSEC. SOLOSEC was evaluated in three clinical trials of patients diagnosed with bacterial vaginosis: two placebo-controlled trials (Trial 1 n=215, Trial 2 n=189) and one uncontrolled safety trial (Trial 3 n=321).
All patients received a single oral dose of study medication or placebo. Trial 1 evaluated a 1 g (this dose is not approved) dose (n=71) and a 2 g dose (n=72) of SOLOSEC. Trial 2 evaluated a 2 g dose (n=125). The population was female, aged 15 to 54 years. Patients in the placebo- controlled trials were primarily Black or African American (54%) or Caucasian (41%).
There were no deaths in the trials. Two patients in Trial 3 discontinued due to vulvovaginal candidiasis in the SOLOSEC-treated arm.
Most Common Adverse Reactions
Among 197 patients treated with a single 2 g dose of SOLOSEC in the two placebo-controlled trials, Trial 1 and 2, adverse reactions were reported by approximately 29% of patients. Table 1 displays the most common adverse reactions (≥ 2 % in SOLOSEC-treated patients) in these two trials.
Table 1: Adverse Reactions Occurring (≥ 2 % SOLOSEC-Treated Patients) in the Pooled Placebo-Controlled Trials 1 and 2 in Adult Women with Bacterial Vaginosis
| Adverse Reaction | SOLOSEC N=197 n (%) |
Placebo N=136 n (%) |
| Vulvo-vaginal candidiasis | 19 (9.6) | 4 (2.9) |
| Headache | 7 (3.6) | 2 (1.5) |
| Nausea | 7 (3.6) | 1 (0.7) |
| Diarrhea | 5 (2.5) | 1 (0.7) |
| Abdominal pain | 4 (2.0) | 2 (1.5) |
| Vulvovaginal pruritus | 4 (2.0) | 2 (1.5) |
Among the 321 patients in an uncontrolled trial, Trial 3, adverse reactions were reported in 30% of patients. Vulvovaginal candidiasis (8.4%), nausea (5.3%), vomiting (2.5%) and dysgeusia (3.4%) were the most common adverse reactions reported in this trial.
Postmarketing Experience
The following adverse reactions have been reported during use of other formulations of secnidazole 2 g outside of the United States. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Reported adverse reactions were nausea, dysgeusia, abdominal pain, headache, and vomiting.
