Tomorrow I leave for Baltimore, to begin my chemotherapy treatment. Below is a description of the treatment:
What is Revimmune?
Revimmune uses an ultra-high intensity, short-course of an intravenous formulation of an approved drug (cyclophosphamide), in a new patent-pending method to "reboot" a patient's immune system, thereby eliminating the autoimmunity, whereas current therapies including oral cyclophosphamide are used chronically to try to suppress the inflammation of autoimmunity. Based on long-term follow-up showing complete remissions, there is substantial evidence that Revimmune has the potential to cure cases of severe refractory autoimmune diseases such as aplastic anemia and myasthenia gravis. Accentia's lead indication for Revimmune is multiple sclerosis (MS).
Developed by Dr. Richard Jones, Dr. Robert Brodsky, and colleagues at the Johns Hopkins University School of Medicine, Revimmune works by temporarily eliminating peripheral immune cells, including the immune cells causing the autoimmunity, while selectively sparing the stem cells in the bone marrow. Investigators at Hopkins discovered that stem cells uniquely have high levels of a particular protective enzyme that can be measured in advance of therapy, which makes them impervious to Revimmune, and allows the surviving stem cells to give rise to the new immune system over 2 to 3 weeks. The newly reconstituted peripheral immune system typically lacks the misdirected immunity to self-antigens, which is characteristic of autoimmune diseases.
Studies at Johns Hopkins University School of Medicine by Dr. Jones, Dr. Brodsky, and colleagues have demonstrated the potential benefits of Revimmune in a variety of autoimmune diseases.
Revimmune treatment of 20 Multiple Sclerosis patients has resulted in the following successful outcomes in 2 published studies from C. Krishnan, D. Kerr et al.(2) and D. Gladstone et al.(3):
All patients have had a reduction or elimination of new and enhancing lesions on the MRI
No patient has had a clinical exacerbation following treatment and most patients have had a reduction in EDSS and an improvement in the MSFC following treatment
During follow-up, no patients increased their baseline EDSS scores by more than 1.0
No patient had a new lesion on brain magnetic resonance imaging; no patient showed any enhancing lesions
