A Phase I Study of Idasanutlin Alone or with Chemotherapy in Pediatric and Young Adult Patients with Recurrent or Persistent Solid Tumors

Full Title

A Phase I/II Multicenter, Open-Label, Multi-Arm study Evaluating the Safety, Tolerability, Pharmacokinetics, and Preliminary Activity of Idasanutlin in Combination with Either Chemotherapy or Venetoclax in the Treatment of Pediatric and Young Adult Patients with Relapsed/Refractory Acute Leukemias or Solid Tumors

Purpose

The purpose of this study is to find the highest dose of the investigational drug idasanutlin that can be given safely alone or combined with chemotherapy in children and young adults with childhood cancers that have come back or continued to grow despite prior treatment. Idasanutlin works by blocking a protein on cancer cells called MDM2, which cancer cells need to grow.

Patients in this study will receive idasanutlin alone or in combination with cyclophosphamide and topotecan, which are standard chemotherapy drugs. Idasanutlin is taken orally (by mouth) and the chemotherapy drugs are given intravenously (by vein).
