Fase IIa randomisert placebokontrollert studie: mesenkymale stamceller som en sykdomsmodifiserende terapi for iPD
11. august 2026 oppdatert av: Mya Schiess
En randomisert, dobbeltblind, placebokontrollert studie av allogene benmargsavledede mesenkymale stamceller som en sykdomsmodifiserende terapi for idiopatisk Parkinsons sykdom
Hensikten med denne studien er å velge det sikreste og mest effektive antallet gjentatte doser av allogene benmargsavledede mesenkymale stamceller (MSC) infusjoner for å bremse progresjonen av Parkinsons sykdom (PD).
