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 Pylera plus omeprazole (OBMT) to eradicate Helicobacter pylori was assessed in an open-label, randomized, active-controlled clinical trial conducted in North America. The duration of treatment was 10 days with 147 patients exposed to Pylera plus omeprazole (OBMT) and 152 exposed to control, consisting of omeprazole, amoxicillin, and clarithromycin (OAC). The age of the population in the study ranged from 18 to 75 years, with 59% male patients and 59% Caucasian patients.

Adverse drug reactions were reported in 58% of patients in the OBMT group and 59% of patients in the OAC group. There were no adverse reactions leading to discontinuation of the study during the clinical trial.

Adverse reactions with an incidence of ≥ 5% in OBMT group include abnormal feces, diarrhea, nausea, and headache. Adverse drug reactions with an incidence of ≥ 5% in OAC group include diarrhea, dysgeusia, dyspepsia, nausea and headache.

Table 2 lists adverse reactions with an incidence of ≥ 1%, in either groups (OBMT vs OAC) and in order of decreasing incidence for the OBMT group.

Postmarketing Experience

Additionally, the following adverse reactions, presented by system organ class in alphabetical order, have been identified during post approval use of Pylera. 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.

• Gastrointestinal disorders: abdominal distention, eructation, flatulence
• General disorders and administration site conditions: chest discomfort, fatigue.
• Infections and infestations: candidiasis.
