Solid Tumor Treatment with MK-1775 and Irinotecan – Phase I/II

Study of MK-1775 (AZD1775) in Combination with Oral Irinotecan in Children, Adolescents, and Young Adults with Relapsed or Refractory Solid Tumors

Protocol Description

Through this Children’s Oncology Group (COG) study, researchers are evaluating the effectiveness of the drug MK-1775 (AZD1775) given in combination with irinotecan against recurrent tumors and tumors that will not respond to standard therapy. MK-1775 has shown potential in laboratory tests. This program evaluates the effects of the drug on tumors, as well as its side effects and how the body processes it. This study is an initiative of COG’s Pediatric Early Phase Clinical Trial Network of which UPMC Children’s Hospital of Pittsburgh is a part.
