6.1 Clinical Trials Experience
The safety of KAPIDEX was evaluated in 4548 patients in
controlled and uncontrolled clinical studies, including 863 patients treated for
at least 6 months and 203 patients treated for one year. Patients ranged in age
from 18 to 90 years (median age 48 years), with 54% female, 85% Caucasian, 8%
Black, 4% Asian, and 3% other races. Six randomized controlled clinical trials
were conducted for the treatment of EE, maintenance of healed EE, and
symptomatic GERD, which included 896 patients on placebo, 455 patients on
KAPIDEX 30 mg, 2218 patients on KAPIDEX 60 mg, and 1363 patients on lansoprazole
30 mg once daily.
As 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.
Most Commonly Reported Adverse
Reactions
The most common adverse reactions (≥2%) that occurred at a higher incidence
for KAPIDEX than placebo in the controlled studies are presented in Table
2.

Adverse Reactions Resulting in
Discontinuation
In controlled clinical studies, the most common adverse reaction leading to
discontinuation from KAPIDEX therapy was diarrhea (0.7%).
