Trial title Response to oral lansoprazole of inorganic pyrophosphate levels in patients with Grönblad- Stranberg disease Pseudoxanthoma Elasticum

Trial design Double-blind placebo-controlled randomised two-stage crossover clinical trial with each patient serving as their own control and reducing the number of patients to confirm our hypothesis

Principal Investigator Dr Pedro Valdivielso Felices Participating centres Virgen de la Victorias Universitary Hospital in Malaga and Virgen de la Macarenas Universitary Hospital in Seville

Duration of the trial 12 months Expected start date December 2019 Objectives PrincipalTo verify the changes in plasma PPi and the main molecules that regulate it NPP1-3 TNAP after oral administration of lansoprazole in patients diagnosed with PXE

Description of treatment

Selection20 patients who meet all the criteria for inclusion and none for exclusion

Randomisation and 1st stage Patients will receive lansoprazole 30mgday or their placebo for 8 weeks

Wash-out After 8 weeks all treatment will be suspended for 15 days 2nd stage crossed Treatment is crossed each patient serves as his or her own control
