title: Phase II study of D.651, an oral vaccine designed to prevent recurrences of vulvovaginal candidiasis.
abstract: A vaccine has been prepared with ribosomes of Candida albicans serotypes a and b plus, as adjuvant, membrane proteoglycan from a nonencapsulated Klebsiella pneumoniae. A preliminary phase II trial without placebo control was conducted in 22 women with a history of frequent recurrences of vulvovaginal candidiasis (VVC). Initially, all the patients were treated locally with an antimycotic cream. Beginning at the same time, vaccine was taken orally in capsules containing 0.55 microgram active components. It was administered intermittently over six months, groups of women taking doses of two, three, six or nine capsules. Tolerance was excellent except for mild nausea, probably due to the excipients, in two patients taking nine capsules. Twenty patients completed the study. Only seven of them had a documented recurrence of VVC during the 6 months on vaccine. No recurrence occurred in the eight women taking six or nine capsules per day. Before the study, these 20 patients had had an average of 3.59 attacks of VVC per 6 months. On vaccine, the average rate of recurrence was only 0.55 attacks per 6 months. A multicentre placebo-controlled study of the efficacy of this vaccine is in progress to validate these encouraging preliminary results.
