This protocol is being used (in roughly the same form) in i.a.:

  • University Hospital of Antwerp (Belgium)
  • Karonlinska University Hospital, Stockholm (Sweden)
  • Heidelberg University Hospital (Germany)
  • The RAM-MS study
  • Note: This protocol is similar to the protocol used in the MIST study. In that protocol, however, a higher dose of methylprednisolone (1000 mg) is given before administering ATG (Source: doi:10.1001/jama.2018.18743)
  • Northwestern University, Chicago (USA)
  • Uppsala University (Sweden)
  • Sheffield Teaching Hospitals NHS Foundation Trust (UK)
  • University of Sao Paulo (Brasil)

  • BCNU (carmustine) 300 mg/m2
  • Cytarabine (Ara-C) twice daily 100 mg/m2 (per block)
  • Etoposide twice daily 100 mg/m2 (per block)

  • hATG 30 mg/kg (per block) -note: this is horse derived ATG unlike the rabbit variant used in all other centers. There is no evidence for a difference in the effectiveness for treatment of MS. (MakatiMed’s choice for hATG is due to availability)-

Myeloablative high intensity protocol

Note that low, intermediate and high intensity protocols are terms used by the EBMT. The protocols of Singapore and India would qualify as “low intensity”, non-myeloablative. The protocols of Russia and Mexico are even lower in intensity than what the EBMT refers to as “low intensity” protocols.
