What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of subjects with adverse events (AEs) or serious AEs (SAEs)	An AE is any untoward medical occurrence in a subject or clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Any untoward event resulting in death, life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, congenital anomaly/birth defect, any other situation according to medical or scientific judgment that may not be immediately life-threatening or result in death or hospitalization but may jeopardize the subject or may require medical or surgical intervention will be categorized as SAE.	Up to 7 weeks in each cycle
Number of subjects with abnormal change from Baseline in laboratory parameters	Blood sample will be collected to evaluate laboratory parameters.	Baseline and up to 7 weeks in each cycle
Number of subjects with Optimally Tolerated regimen	Optimally Tolerated regimen is a dose regimen where 1 out of 6 subjects experiences a dose-limiting toxicity (DLT).	Up to 7 weeks in each cycle
