Phase I Clinical Trial of the Wee1 Inhibitor Adavosertib (AZD1775) with Irinotecan in Children with Relapsed Solid Tumors: A COG Phase I Consortium Report (ADVL1312).

ABSTRACT:

Purpose

Adavosertib (AZD1775), an inhibitor of WEE1 kinase, potentiates replicative stress induced by oncogenes or chemotherapy. Antitumor activity of adavosertib has been demonstrated in preclinical models of pediatric cancer. This phase I trial was performed to define dose-limiting toxicities (DLT), recommended phase II dose (RP2D), and pharmacokinetics of adavosertib in combination with irinotecan in children and adolescents with relapsed or refractory solid tumors or primary central nervous system tumors.

Patients and methods

Using a 3+3 escalation design, five dose cohorts of the combination of adavosertib and irinotecan (50/70; 65/70; 65/90; 85/90; 110/90 mg/m²/day) delivered on days 1-5 of a 21-day cycle were studied. Pharmacokinetics and analysis of periph
