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 with rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The safety of a single dose of CAMBIA was evaluated in 2 placebo-controlled trials with a total of 634 migraine patients treated with CAMBIA for a single migraine headache. Following treatment with diclofenac potassium (either CAMBIA or diclofenac potassium immediate-release tablets [as a control]), 5 subjects (0.8%) withdrew from the studies; following placebo exposure, 1 subject (0.2%) withdrew. The most common adverse reactions (i.e., that occurred in 1% or more of CAMBIA-treated patients) and more frequent with CAMBIA than with placebo were nausea and dizziness (see Table 1).
Table 1: Adverse Reactions With Incidence > 1% and Greater Than Placebo in Studies 1 and 2 Combined
The most common adverse events resulting in discontinuation of patients following CAMBIA dosing in controlled clinical trials were urticaria (0.2%) and flushing (0.2%). No withdrawals were due to a serious reaction.
The following adverse reactions have been identified during post approval use of diclofenac or other NSAIDs. 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.
