Results of a Johns Hopkins study may explain why a chemotherapy drug
called cyclophosphamide prevents graft - versus - host (GVHD) disease in people who receive bone marrow transplants.
Patients given the 200 mg dose saw the most promising results and the study was able to conclude that, «phytochemicals from the avocado fruit can be utilized in making active chemoprotective ingredients (s) for lowering the side effect of chemotherapy
like cyclophosphamide in cancer therapy».
The first step was to taper off immunosuppressives like prednisone and
cyclophosphamide as quickly as possible.
«We've known for some time that giving
cyclophosphamide after a transplant helps prevent GVHD, and our study provides an important piece of the puzzle for why it works.»
But the two most recent deaths leading to the second clinical hold occurred in November after resumption of the
original cyclophosphamide - only protocol, which occurred when the ROCKET trial was resumed just 2 weeks after the first hold was imposed.
Johns Hopkins physicians also found that post-transplant
cyclophosphamide enabled safe administration of new, half - matched bone marrow transplants in addition to traditional, fully matched ones.
The scientists also showed, in lab - cultured human cells, that an ALDH - blocking drug strips regulatory T - cells of their ability to grow and protect themselves
from cyclophosphamide.
They found that
cyclophosphamide kills all of the donor's transplanted bone marrow cells except for stem cells containing high levels of an enzyme called aldehyde dehydrogenase (ALDH).
Some of the first clues to
how cyclophosphamide works were also discovered in the 1980s by Johns Hopkins scientists.
Much like chemotherapy's well - known ability to decrease red and white blood cell precursors transiently, methotrexate or
cyclophosphamide depleted fat cell precursors, leading to much decreased fat storage.

Exposure to topical insecticides and herbicides, obesity,
cyclophosphamide administration and particular types of breed are believed to be the probable risk factors.
In the early 2000s, Johns Hopkins scientists Leo Luznik and Ephraim Fuchs found that giving patients high doses
of cyclophosphamide — a drug derived from nitrogen mustard and used to treat blood cancers — three days after bone marrow transplant successfully thwarts acute and chronic GVHD.
Cancer - fighting drugs (cytotoxic drugs),
including cyclophosphamide, methotrexate and doxorubicin, have toxic effects on cells and are commonly used in chemotherapy to kill cancer cells.
Johns Hopkins and other cancer researchers report that a very short course of a chemotherapy drug,
called cyclophosphamide, not only can prevent a life - threatening immune response in some bone marrow transplant recipients, but also can eliminate such patients» need for the usual six months of immune suppression medicines commonly prescribed to prevent severe forms of this immune response.
The protocol of ZUMA - 1 calls for patients to receive fludarabine plus
cyclophosphamide for 3 days before infusion of the target dose of KTE - C19, in which a patient's T cells are genetically modified to express a CAR that is designed to target the antigen CD1.
In this study, patients began treatment with chemotherapy
using cyclophosphamide and topotecan and the experimental monoclonal antibody hu14.18 K322A.
One study used a pancreatic cancer vaccine with modified pancreatic cancer cells known as GVAX, alongside the chemotherapy
drug cyclophosphamide and a special bacterium that boosts the immune response.
In the ROCKET trial assessing JACR015, the first clinical hold imposed in July followed the deaths of three patients, which the company blamed on a change to the trial's original protocol to precondition patients by using a combination of
cyclophosphamide and fludarabine.
In a statement yesterday, Juno said it has asked the FDA for permission to change the trial protocol by ending the use of fludarabine as a preconditioning drug along with
cyclophosphamide and going back to the trial's earlier protocol — changed during the second quarter — of cyclophosphamide preconditioning alone.
If you are receiving chemotherapy (especially cyclosporine, methotrexate, bromocriptine,
