Description
Curator's Comment: description was created based on several sources, including http://aptose.com/apto-253/

APTO-253 is a novel small molecule that can induce expression of the genes that code for the Krüppel-like factor 4 (KLF4) master transcription factor and for the p21 cell cycle inhibitor protein, and can inhibit expression of the c-Myc oncogene, leading to cell cycle arrest and programmed cell death (apoptosis) in human-derived solid tumor and hematologic cancer cells. A Phase 1 study with APTO-253 was completed and demonstrated modest clinical activity in patients with colon cancer, acute leukemia, myelodysplastic syndrome, hematological malignancies and non-small cell lung cancers.

Sample Use Guides

APTO-253 HCl will be given in ascending doses starting from 20 mg/m2 until the maximum administered dose or appropriate dose is reached. Patients will be treated on APTO-253 HCl for at least 1 cycle (28 days) for safety evaluation.
Route of Administration: Intravenous
APTO-253 showed potent antiproliferative activity in vitro against a panel of blood cancer cell lines, with ηM IC50 values in acute myelogenous leukemia (6.9 - 305 ηM), acute lymphoblastic leukemia and chronic myeloid leukemia (39 – 250 ηM), non-Hodgkin’s lymphoma (11 – 190 ηM) and multiple myeloma (72 – 180 ηM).
