Details and patient eligibility


The primary objective of the study is to investigate neuroregenerative efficacy (proof of concept) of intrathecal treatment with autologous MSCs as measured by neurophysiological parameters in patients with progressive MS. Secondary objectives are to assess neuroregenerative efficacy as measured by other neurophysiological parameters as well as clinical, opthalmological and MRI modalities, and to assess safety of the treatment procedure.

Full description

Prospective, interventional, randomized, placebo-controlled, cross-over study. Patients are randomized to either treatment arm A or B. Patients in both treatment arms receive intrathecal autologous MSCs, arm A at baseline and arm B at six months. All patients undergo bone marrow (BM) aspiration prior to baseline. Patients in treatment arm A receive intrathecal autologous MSCs whereas patients in treatment arm B receive placebo. The treatment is blinded for the patients. The BM aspirate from patients in treatment arm B is processed, cryopreserved and stored in a biobank. At six months, all patients undergo a second BM aspiration. Patients in treatment arm A now receive placebo. The BM aspirate from patients in treatment arm A is processed, cryopreserved and stored in a biobank. Patients in treatment arm B receive intrathecal autologous MSCs. The treatment is blinded for the patients. Primary outcome is assessed at six months and secondary outcomes are assessed at six, twelve and eighteen months post baseline. Investigator assessing outcomes are blinded to patient treatment allocation.

Exclusion criteria

  • Any illness or prior/ongoing treatment that in the opinion of the investigators would jeopardize the ability of the patient to tolerate autologous stem cell treatment

  • Estimated glomerular filtration rate <60 ml/min/1.73 m2 or known renal failure
  • Bleeding or clotting diathesis or the use of antithrombotic or anticoagulative treatment
  • Platelet (thrombocyte) count <100 x 10*9/L
  • Participation in another experimental clinical study within the preceding 12 months
  • Contraindications to MRI
  • Prior or current major depression
  • Prior or current psychiatric illness, mental deficiency or cognitive dysfunction influencing the patient ability to make an informed consent or comply with the treatment and follow-up phases of this protocol.
  • Pregnancy or risk of pregnancy (this includes patients that are unwilling to practice active contraception during the duration of the study), breastfeeding or lactation
  • History of autologous/allogenic bone marrow transplantation or peripheral blood cell transplant
  • Known hypersensitivity against paracetamol, codein or xylocain
  • Diagnosis or strong suspicion of polyneuropathy
