This is true for ferritin levels and iron levels in the organs as well, it is important for patients to go regularly for transfusions in order to maximize good health, normal ferritin levels run anywhere between 24 and 336 ng/ml, hematologists generally do not begin chelation therapy until ferritin levels reach at least 1000 ng/ml. It is more important to check iron levels in the organs through MRI scans, however, than to simply get regular blood tests to check ferritin levels, which only show a trend, and do not reflect actual organ iron content. Gene therapy
Gene therapy, as well as, bone marrow transplant are also possible treatments for the disorder, but each have their own risks at this point in time. Bone marrow transplantation is the more used method between the two, whereas researchers are still trying to definitively establish the results of gene therapy treatment. It generally requires a 10/10 HLA matched donor, however, who is usually a sibling. As most patients do not have this, they must rely on gene therapy research to potentially provide them with an alternative. CDA at both clinical and genetic aspects are part of a heterogeneous group of genetic conditions. Gene therapy is still experimental and has largely only been tested in animal models until now.
The binding of isatuximab to CD38 on multiple myeloma (MM) cells leads to a trigger to several mechanisms leading to direct apoptosis of target cancer cells. The triggered pathways are the caspase-dependent apoptotic and the lysosome-mediated cell death pathway in MM cells.It is used in a combination with dexamethasone and pomalidomide. The drug is thus to treat patients with multiple myeloma. Restrictions for the use of isatuximab is that the patients have to be adults who have at least received two previous treatments with lenalidomide and a proteasome inhibitor.Isatuximab is currently also being tested in a Phase II trial as a monotherapy against refractory/recurrent systemic light-chain amyloidosis. Efficacy and side effects
Efficacy
A Phase III study of patients with refractory and relapsed MM, who were resistant to lenalidomide and a proteasome inhibitor, and could not have received daratumumab, another anti-CD38 monoclonal antibody was published in 2019 (ICARIA-MM). The addition of isatuximab to pomalidomide and dexamethasone improved progression free survival to 11.5 months compared to 6.5 months, with an overall response rate of 63%. Side effects
Adverse reactions to isatuximab-irfc may include neutropenia, infusion-related reactions and/or secondary primary malignancies. Of these three the most commonly occurring ones are the infusion-related reactions. Examples of the most frequent symptoms of infusion-related reactions are dyspnea, cough, chills, and nausea, while the severest signs and symptoms included hypertension and dyspnea. Effects on animals
The activity of isatuximab has been researched in mouse tumor models. It has been proven that isatuximab leads to antitumor activity in MM cells.
