Design outcomes

Primary

MeasureTime frame
Part 1: Frequency and severity of Adverse Events (AEs), Serious Adverse Events, (SAEs), Dose Limiting Toxicity (DLT), withdrawals due to AEs Part2: Objective response rate (ORR) after the daily dosing *induction* period of GSK3745417 Frequency and severity of Adverse Events (AEs), Serious Adverse Events, (SAEs), Dose Limiting Toxicity (DLT), withdrawals due to AEs during *maintenance* dosing

Secondary

MeasureTime frame
Part 1: GSK3745417 concentrations in plasma or PK parameters Part 2: AEs, SAE, AESIs leading to dose modifications or delays GSK3745417 concentrations in plasma or PK parameters Exploratory: Part 1: Objective response rate (ORR) as measured by standard disease specific response criteria. The relationship between GSK3745417 exposure (e.g., concentration, Cmax, or other exposure parameter) and the following safety parameters may be included based on the availability of data and appropriateness: • AEs leading to dose reductions or delays • Change from baseline in safety laboratory parameters • Change from baseline in other safety assessments (such as vital signs, ECG) • Changes in cardiac QT duration corrected for heart rate by Fridericia*s formula (QTcF) and/or other safety parameters in relation to GSK3745417 exposure markers. Association between dose and PD parameters. PD assessment may include apoptotic markers and/or immune activation (e.g., serum cytokines, T cell activation markers, acute phase proteins) in peripheral blood samples and bone marrow. Association between GSK3745417 dose and ORR as measured by standard response criteria. Assessment may include: induction of apoptosis markers, cell killing, and changes in immune activation status based on induction of cytokines, immune profiles and gene signatures in peripheral blood and/or bone marrow. Other biomarkers including genetic analysis (DNA) in blood and/or bone marrow and assessments by immunohistochemistry (IHC) or related technologies Part 2: DoR, if data permit Milestone EFS rate at 6 months AEs leading to dose reductions or delays Change from baseline in safety laboratory parameters Change from baseline in other safety assessments (such as vital signs, ECG) Changes in cardiac QT duration corrected for heart rate by Fridericia*s formula (QTcF) and/or other safety parameters in relation to GSK3745417 exposure markers as appropriate.
