| DB00631 | Clofarabine | Clofarabine is a purine nucleoside antimetabolite that is being studied in the treatment of cancer. It is marketed in the U.S. and Canada as Clolar. In Europe and Australia/New Zealand the product is marketed under the name Evoltra. Clofarabine is used in paediatrics to treat a type of leukaemia called relapsed or refractory acute lymphoblastic leukaemia (ALL), only after at least two other types of treatment have failed. It is not known if the drug extends life expectancy. Some investigations of effectiveness in cases of acute myeloid leukaemia (AML) and juvenile myelomonocytic leukaemia (JMML) have been carried out. |
| DB13874 | Enasidenib | Enasidenib is an orally available treatment for the treatment of adult patients with relapsed or refractory acute myeloid leukemia (AML) with specific mutations in the isocitrate dehydrogenase 2 (IDH2) gene, which is a recurrent mutation detected in 12-20% of adult patients with AML [A20344, A20345]. Patients eligible for this treatment are selected by testing the presence of IDH2 mutations in the blood or bone marrow. This small molecule acts as an allosteric inhibitor of mutant IDH2 enzyme to prevent cell growth, and it also has shown to block several other enzymes that play a role in abnormal cell differentiation. First developed by Agios Pharmaceuticals and licensed to Celgene, enasidenib was approved by U.S. Food and Drug Administration on August 1, 2017. |
| DB00056 | Gemtuzumab ozogamicin | Gemtuzumab ozogamicin is a recombinant humanized IgG4 kappa antibody which is conjugated with calicheamicin derivative, a cytotoxic antitumor antibiotic isolated from fermentation of Micromonospora echinospora ssp. calichensis. Gemtuzumab ozogamicin has approximately 50% of the antibody loaded with 4-6 moles calicheamicin per mole of antibody [FDA Label]. The antibody is specifically directed against the CD33 antigen present on leukemic myeloblasts in most patients with acute myeloid leukemia (AML). By binding to the CD33 antigen on tumors, the cytotoxic agent blocks the growth of cancerous cells and causes cell death. Marketing approval of gemtuzumab ozogamicin was granted on May 17, 2000 by FDA as a treatment for patients with CD33-positive AML in first relapse who are 60 years of age or older and who are not considered candidates for cytotoxic chemotherapy [A98]. However, it was voluntarily withdrawn from the market in 2010 due to safety concerns, increased patient deaths and insufficient evidence of clinical benefit during confirmatory trials [L941]. On September 1 2017, gemtuzumab ozogamicin was again approved for the treatment of adults with newly diagnosed CD33-positive acute myeloid leukemia but with a lower dosing regimen and a different schedule in combination with chemotherapy or on its own [L941]. It is also indicated for the treatment of patients aged 2 years and older with CD33-positive AML who have experienced a relapse or who have not responded to initial treatment (refractory) [L941]. |
