Design outcomes

Primary

MeasureTime frame
Main Objective: Investigation of maximum tolerated dose ;Secondary Objective: •Safety/Tolerability •Efficacy;Primary end point(s): Identification of the maximum tolerated dose (MTD) of the investigational medicinal product. ;Timepoint(s) of evaluation of this end point: When MTD is achieved.

Secondary

MeasureTime frame
Secondary end point(s): Determination of safety and tolerability of P1101 in patients with polycythaemia vera. An exploratory analysis of efficacy and biomarker modulation will be also performed.;Timepoint(s) of evaluation of this end point: Throughout the whole study. Efficacy: The first time after 12 weeks and then every 10 weeks thereafter. Biomarker: Every 2 weeks until MTD, then 5 times every 2 weeks followed by an optional intensive biomarker blood sampling schedule (6 times in the course of 2 weeks).
