A Phase 1 Study Evaluating the Safety and Pharmacokinetics of ABT-348 as monotherapy, and in combination with azacitidine, in Subjects with Advanced Hematologic Malignancies
The goal of this clinical research study is to find the highest tolerable dose of ABT-348 that can be given alone or with Vidaza (azacitidine) to patients with either leukemia or MDS. The safety of this drug or drug combination will also be studied. ABT-348 is designed to block proteins that cause cancer cells to grow and multiply. ABT-348 is also designed to block the formation of new blood vessels for the tumor. This may cause the cancer cells to die. This is the first study using ABT-348 in humans. Azacitidine is designed to block certain proteins in cancer cells whose job is to stop the function of the tumor-fighting proteins. By blocking these proteins, the tumor-fighting genes may be able to work better.
Disease Group: Leukemia
Treatment Agent: ABT-348,Azacitidine
Treatment Location: Both at MD Anderson & outside MD Anderson at one or more Collaborating Sites or Institutions
Estimatated Length of Stay in Houston: none
Return Visit: weekly
Home Care: NA
The primary objectives of this study are to: Determine safety and pharmacokinetics of orally and intravenously (IV) administered ABT-348 as monotherapy or when in combination with azacitidine in subjects with advanced hematologic malignancies. The secondary objectives are to: Determine the maximum tolerated dose (MTD) and recommended Phase 2 dose (RPTD) of ABT-348 when administered orally and IV as a monotherapy or when in combination with azacitidine in subjects with advanced hematologic malignancies. Exploratory research to evaluate the effect of food on the oral bioavailability of ABT-348 and to find biomarkers that may serve as surrogates for clinical endpoints in future ABT-348 studies or that may be predictive of ABT-348 activity will be conducted.
