Summary

This is a phase I, open-label study to assess the safety, tolerability, pharmacokinetics(PK) and anti-tumour activity of adavosertib in Japanese patients with advanced solid tumours. This study consists of 2 parts, monotherapy (part A) and chemotherapy combination (part B). At least 3, or up to 6, evaluable Japanese patients with advanced solid tumours will be enrolled in each cohort to confirm the tolerability.

Detailed description

Objectives: Primary objective: Part A: To assess the safety and tolerability, describe any dose-limiting toxicity (DLT) for adavosertib Secondary objective: To determine the PK profile of adavosertib To describe adavosertib's preliminary anti-tumour activity using the Response Evaluation Criteria in Solid Tumours (RECIST) v1.1 Part B: To assess the safety and tolerability, describe any dose-limiting toxicity (DLT) for adavosertib in combination with gemcitabine Secondary objective: To determine the PK profile of adavosertib plus gemcitabine To describe preliminary anti-tumour activity of adavosertib in combination with gemcitabine using the Response Evaluation Criteria in Solid Tumours (RECIST) v1.1 To assess the drug interaction between adavosertib and gemcitabine Overall design: This is a phase I, open-label study to assess the safety, tolerability, PK and anti-tumour activity of adavosertib in Japanese patients with advanced solid tumours. This study consists of 2 parts, monotherapy (part A) and chemotherapy combination (part B). At least 3, or up to 6, evaluable Japanese patients with advanced solid tumours will be enrolled in each cohort. The total number of subjects will depend upon the available data in each cohort and the Safety Review Committee (SRC)'s decision. Number of Subjects: At least 3, or up to 6, evaluable Japanese patients with advanced solid tumours will be enrolled in each cohort. Treatments and treatment duration: Subjects in each part will receive the study treatments as described below: Part A: Adavosertib by mouth (PO) once daily (QD) for 5 days ON and 2 days OFF for week 1 and 2 of a 21 days cycle. Part B: Adavosertib PO will be taken QD on Days 2, 3, 9, 10, 16, and 17. Gemcitabine will be administered by intravenous infusion according to institutional standards on Days 1, 8, and 15 of each 28-day cycle. Subjects will be allowed to continue adavosertib until disease progression, intolerable toxicity, or discontinuation criteria have been met.
