Description of intervention(s) / exposure
Autologous Haematopoietic Stem Cell Transplantation
Participants are assessed using inclusion and exclusion criteria specific for highly active, treatment resistant multiple sclerosis in order to determine whether they are eligible for an Autologous Stem cell transplant as part of the study.
Participants will undergo stem cell collection following intravenous infusion 2g/m2 cyclophosphamide. Intravenous fluids 0.9% Normal Saline(one litre every 6 hours) and mesna (dose 3g/m2) over 5 hours commencing one hour prior to cyclophosphamide, will be prescribed to run concurrently as per current standard practice in the Haematology Unit for malignant conditions. The intravenous fluids will run for 24 hours. This dose of Cyclophosphamide is given as a day patient in day oncology HOC unit (unless admission is determined to be necessary). Other supportive medications eg. anti-emetics as per local guidelines
From day 5 onwards daily GCSF 5mcg/kg twice daily for at least 7 days will be administered sub-cutaneously. The maximum duration for GCSF is 9 days. The duration of GCSF is determined by the level of stem cells in the blood.

Haematopoietic stem cells will then be collected and cryopreserved as per standard operating procedures in the Haematology Department.
Within 4-8 weeks from the collection of stem cells, the participant is hospitalized for the immune ablative and transplantation procedure. The timing of the transplantation procedure is determined by participant health and wellbeing, and availability of resources.The immune ablative regime consists of cyclophosphamide 50mg/kg (total of 200mg/kg) from day -5 to day -2 before transplantation, and rabbit antithymocyte globulin ATG (Thymoglobuline®) 0.5mg/kg intravenous infusion on day -5, 1.0mg/kg on day -4 and 1.5mg/kg pm days -3,-2 and -1. Methylprednisolone 1000mg intravenous infusion is to be infused 30minutes prior to rabbit ATG infusions. An additional 250mg of methylprednisolone should be used in the setting of ATG induced fever. Give mesna IV (40% of the cyclophosphamide dose) in 100 mL of normal saline over 30 minutes before the infusion of cyclophosphamide. Then commence mesna (120% of cyclophosphamide dose) in 1 litre of normal saline over 24 hours at the same time as cyclophosphamide, to finish 24 hours after the last dose of cyclophosphamide (on D-5, D-4, D-3 and D-2).
The collection and transplantation procedures will be performed as per The Alfred hospital's Standard of Care in the Haematology Department ward under the care of Haematologists, and haematology trained nursing staff. The minimum target dose of stem cells is 2 x 10^6 cells. The cells are administered by intravenous infusion.

Outcomes
Primary outcome [1] 319151 0
The primary objective of the cohort study is to assess the safety, as measured by transplant related mortality at Day 100 (defined as death in the first 100 days not due to MS)
Timepoint [1] 319151 0
Day 100 post transplant
Primary outcome [2] 319321 0
To assess the efficacy of HSCT as measured by (a) mean time to first relapse (clinical and MRI), (b) mean time to 3 and 6 month sustained change in EDSS and (c) mean annualised relapse rate in participants with multiple sclerosis refractory to standard therapies.
Timepoint [2] 319321 0
Month 60
Secondary outcome [1] 367138 0
To assess tolerability of the autograft between d100 and d365, particularly with respect to infectious sequelae. This will be assessed by monitoring the occurrence of infectious sequelae as adverse events
Timepoint [1] 367138 0
Day 365 post transplant

Summary
Brief summary
We propose to study the benefits and risks of Autologous Haematopoetic Stem Cell Transplant (AHSCT) in people who have an aggressive form of MS not controlled by conventional treatment. Participants will have AHSCT at The Alfred hospital, and they will be closely monitored for 5 years post the transplant to ensure their safety, and also level of Multiple Sclerosis disease activity.
