Cladribine

The goal of this clinical research study is to learn if cladribine given in combination with low-dose cytarabine (LDAC) and decitabine can help control the disease in patients with AML or MDS. The safety of this drug combination will also be studied. Cladribine is designed to interfere with the cell's ability to process DNA (the genetic material of cells). It can also insert itself into the DNA of cancer cells to stop them from growing and repairing themselves. Cytarabine is designed to insert itself into DNA of cancer cells to stop them from growing and repairing themselves. Decitabine is designed to damage the DNA of cells, which may cause cancer cells to die. This is an investigational study. Cladribine is FDA approved and commercially available for use in patients with hairy cell leukemia. Its use in patients with AML is investigational. Cytarabine is FDA approved and commercially available for use in patients with AML. Decitabine is FDA approved and commercially available for use in patients with MDS. Its use for patients with AML is investigational. Up to 160 patients will take part in this study. All will be enrolled at MD Anderson.

The goal of this clinical research study is to learn if the combination of ruxolitinib with cladribine and venetoclax can help to control the disease in patients with R/R T-PLL.

This phase I/II trial tests the safety, side effects, and effectiveness of tovorafenib in combination with rituximab in patients with classical hairy cell leukemia (cHCL) that has come back after a period of improvement (recurrent) or that has not responded to previous treatment (refractory) and compares the effect of tovorafenib and rituximab to current standard treatment of cladribine and rituximab in cHCL patients that have not yet received treatment. Tovorafenib blocks certain proteins made by the mutated BRAF gene, which may help keep cancer cells from growing. It is a type of kinase inhibitor. Rituximab is a monoclonal antibody. It binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. Cladribine damages the cell's deoxyribonucleic acid and may kill cancer cells. It is a type of antimetabolite. Giving tovorafenib in combination with rituximab may be safe and tolerable and more effective than cladribine with rituximab in treating patients with untreated, recurrent or refractory cHCL.
