Objectives: The aim of this study was to evaluate the pharmacoeconomic profile in Italy of preoperative
treatment with ulipristal acetate at the dose of 5 mg/day for 13 weeks in comparison with placebo prior
to surgical management of symptomatic uterine fibroids.
Study design: The pharmacoeconomic analysis was based on the calculation of incremental cost-
effectiveness ratio (ICER). Effectiveness data were derived from the randomized-controlled trial PEARL-1,
whilst costs data were retrieved from the published literature. A Markov model was employed to
simulate the pattern of costs and two univariate sensitivity analyses tested the robustness of the results.
Results: In comparison with placebo, ulipristal acetate 5 mg for presurgical therapy was estimated to be
associated with an incremental cost of s351 per patient. Costs per patient were s3836 for ulipristal
acetate vs s3485 for placebo. The incremental effectiveness was 0.01931 QALYs per patient (around 7
quality-adjusted days per patient). Hence, the cost effectiveness ratio was calculated to be s18,177 per
QALY gained.
Conclusions: Preoperative use of ulipristal acetate 5 mg in patients with uterine fibroids has a favourable
pharmacoeconomic profile.

Introduction
In women in reproductive age, uterine leiomyomas (or fibroids)
may cause several symptoms including excessive bleeding, pelvic
pain, iron deficiency anemia, infertility and reduced quality of life.
Apart from surgical intervention, there are no medical treatments
that completely eliminate fibroids. However, medical treatments
(e.g. GnRH analogues, oral progestogens and the levonorgestrel
intrauterine system) can effectively be employed in the pre-
operative period for the reduction of symptoms, in particular heavy
bleeding and anemia.
Results of a pivotal randomized controlled trial (the PEARL-I
study [1]) have shown that treatment with ulipristal acetate 5 mg
daily for 12-weeks before planned surgery is effective in
controlling bleeding, decreasing fibroid volume, and reducing
discomfort in women with menorrhagia and anemia. Therefore,
ulipristal acetate 5 mg has been approved for pre-surgical
treatment by the European Medicines Agency (EMA) in 2012
and thereafter by the Italian Medicines Agency (AIFA)[2].
Surgical treatments, currently indicated for these benign
tumors, include hysterectomy and myomectomy and both are
invasive procedures. At present, the drugs approved for the pre-
surgical treatment include Gonadotropin-Releasing Hormone
(GnRH) analogues and ulipristal acetate [3]. Choice of the
treatment is closely related to the attitudes of gynecologists [4].
The main aim of our work was to evaluate the pharmacoeco-
nomic profile in Italy of a single-13-week cycle of ulipristal acetate
5 mg daily in comparison with placebo before surgery for the
management of symptomatic uterine fibroids.
Our pharmacoeconomic analysis was aimed at determining the
costs incurred by patients treated or not treated with ulipristal
acetate 5 mg/day; a Markov model was developed for this purpose.
