Official title
A Phase 1 Study of the Deglycosylated Ricin A Chain-containing Combined Anti-CD19 and Anti-CD22 Immunotoxin Combotox in Combination With High-Dose Cytarabine in Adult Relapsed or Refractory B-lineage Acute Lymphoblastic Leukemia
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This phase I trial studies the side effects and the best dose of deglycosylated ricin A chain-conjugated anti-cluster of differentiation (CD)19/anti-CD22 immunotoxins when given together with cytarabine in treating patients with B-cell acute lymphoblastic leukemia that has come back after a period of improvement (relapsed) or does not respond to treatment (refractory). Immunotoxins, such as deglycosylated ricin A chain-conjugated anti-CD19/anti-CD22 immunotoxins, can find certain cancer cells and kill them without harming normal cells. Drugs used in chemotherapy, such as cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving deglycosylated ricin A chain-conjugated anti-CD19/anti-CD22 immunotoxins with cytarabine may kill more cancer cells.
