Fase IIa randomiseret placebokontrolleret forsøg: mesenkymale stamceller som en sygdomsmodificerende terapi til iPD
11. august 2026 opdateret af: Mya Schiess
Et randomiseret, dobbeltblindt, placebokontrolleret forsøg med allogene knoglemarvs-afledte mesenkymale stamceller som en sygdomsmodificerende terapi for idiopatisk Parkinsons sygdom
Formålet med denne undersøgelse er at udvælge det sikreste og mest effektive antal gentagne doser af allogene knoglemarvs-afledte mesenkymale stamceller (MSC) infusioner for at bremse udviklingen af Parkinsons sygdom (PD).
