iMProveS trial

The iMProveS trial is a 26 week, double blinded, randomized, placebo controlled phase IIa clinical study to investigate the safety, pharmacokinetics and efficacy of oral administration of two doses of odiparcil in patients 16 years and above with MPS type VI receiving enzyme replacement therapy (ERT). The study also has an open label arm with patients currently not on ERT. Enrollment has been completed for this trial.

During the trial patient’s GAG levels in the skin and white blood cells will be measured. Cardiac, pulmonary, ocular and audio function will be monitored and the mobility and pain of the patients assessed.

MPS type VI patients eligible to enroll must be

  • 16 years of age or older
  • Either currently receiving ERT or not have been on ERT for at least 3 months
  • Patients can be located in any country but must be willing to travel to the trial sites

iMProveS is a European trial with study centers, the Royal Free Hospital in London (UK), Villa Metabolica in Mainz (Germany) and Hôpital Femme Mère Enfant in Lyon (France) and São João Hospital in Porto (Portugal) with the participation of Dr. Derralynn Hughes, Prof. Dr. Julia Hennermann, Dr. Nathalie Guffon and Dr. Elisa Leão-Teles.
