A Study to Investigate LP-118, Ponatinib, Vincristine and Dexamethasone in Relapsed/Refractory Acute Lymphoblastic Leukemia (ALL) or Lymphoblastic Lymphoma (LBL)

Description

The purpose of this study is to learn more about LP-118 (an experimental drug) and its side effects and decide on acceptable doses. The purpose of this study is to determine if LP-118 can be given safely with another medicine called ponatinib, that is FDA-approved for the treatment of acute lymphoblastic leukemia.

This study will investigate the combination of LP-118 and ponatinib at different dose levels to find the best doses that can be safely given to patients. This means that enrolled subjects will receive progressive increasing or decreasing doses of these drugs until the maximally tolerated dose is determined. All participants will also receive a standard of care chemotherapy combination consisting of the FDA approved drugs vincristine, dexamethasone and intrathecal (injection into the spinal canal, also called “spinal tap”) methotrexate. This combination is standard of care for relapsed T-ALL/LBL.
