Purpose: The new microemulsion preconcentrate (MEPC) formulation of ciclosp
orin has been developed to reduce problems in intestinal absorption and to
stabilize fluctuations in blood levels. A multicenter, open-label clinical
trial of MEPC was conducted to assess its efficacy and safety in Behcet's d
isease patients with ocular involvement.
Methods: The patient population comprised 17 de novo patients (patients not
previously treated with ciclosporin in the currently available formulation
) and 30 patients whose ciclosporin formulation was switched from the conve
ntional formulation to MEPC. The patients were treated with the test formul
ation for 16 weeks in the former (de novo) group and for 12 weeks in the la
tter (switched) group.
Results: In the de novo group, ocular attacks decreased significantly as co
mpared to the pretreatment incidence in 11 of the 14 patients (78.6%) evalu
ated after MEPC therapy. Ocular attacks also decreased significantly in the
switched group. In the de novo group. visual acuity improved with MEPC the
rapy in 20 of the 28 eyes (71.4%) examined, and the overall efficacy evalua
tion was "improved" or "markedly improved" in 13 of the 16 patients evaluat
ed (81.3%). The one case each of onset of neuro-Behcet's disease and intest
inal Behcet's disease observed in the de novo group were regarded as advers
e reactions.
Conclusion: It was concluded that ciclosporin MEPC is useful for controllin
g the ocular symptoms of Behcet's disease, and that it can be used as effec
tively and safely as the conventional formulation. Jpn J Ophthalmol 1999;43
