measure: Progressionfree free survival (PFS)
time frame: Assessed every 9 weeks with RECIST from the first dose of adavosertib until disease progression. Expected to be for up to 3 months.
description: Defined as the time from the first dose of study treatment until the date of objective disease progression or death by any cause (in the absence of progression), regardless of whether the subject withdraws from the study or receives another anti-cancer therapy prior to progression
measure: Part B: the drug interaction between adavosertib and gemcitabine.
time frame: Part B : Samples will be collected on Cycle 1 Day 2,3 and even Cycle Day 2 for adavosertib and Cycle 1 Day 1 for gemcitabine. (each cycle is 28 days)
description: PK parameters will be derived using standard, non-compartmental methods
measure: Part B: The ctDNA samples will be analysed for predictive biomarkers of response to treatment.
time frame: Part B: at screening
description: The samples may be used to develop and validate future in vitro diagnostic tests to identify patients most likely to respond to the treatment.
measure: Part B: The ctDNA samples will be used for additional exploratory research for efficacy, tolerability, or safety assessment.
time frame: Part B: Cycle 1 Day 1 (predose), discontinuation, and progression (each cycle is 28 days).
description: These samples will be used for additional exploratory research which may include but is not limited to interrogation of changes in genetic alterations associated with response or resistance to treatment as well as the dynamics of the biomarkers on treatment and potential mechanisms of resistance to treatment.
measure: Part A: Optional exploratory biomarker research in genetic samples from subjects who have consented to participate in the genetic analysis component of the study and exploratory biomarker research for efficacy, tolerability, or safety assessment.
time frame: Part A: Cycle 1 Day 1 (each cycle is 21 days).
description: To conduct potential future exploratory research into factors that may influence the progression of cancer and/or response to adavosertib.
measure: Part B:Exploratory analyses may be undertaken on the data generated from tumour tissue to identify biomarkers of sensitivity and resistance to treatment and to increase our understanding of the disease (consenting participants only.)
time frame: Part B: at screening
description: To conduct potential future exploratory research into factors that may influence the progression of cancer and/or response to adavosertib. This exploratory analysis may include immunological biomarkers such as PD-L1 expression and tumour infiltrating lymphocytes.
