A Study to Evaluate Sapablursen (Formerly ISIS 702843, IONIS-TMPRSS6-LRx) in Patients With Polycythemia Vera

Study Purpose

The main purpose of this study is to evaluate the efficacy of sapablursen in reducing the frequency of phlebotomy and in improving quality of life assessments in participants with polycythemia vera.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years - 90 Years
Gender	All

Additional Details

This is a Phase 2a, multi-center, randomized, open-label study of sapablursen in up to 40 participants with PD-PV. The study consists of 4 periods: 1) Screening Period: up to 7 weeks; 2) Treatment Period: 37 weeks 3) Treatment Extension Period: 36 weeks; 4) Post-treatment Period: 13 weeks. In the Treatment Period, study drug is given by subcutaneous (under the skin) injection(s). There will be a total of 9 doses given over about 8 months. In the Treatment Extension Period, there will be a total of 9 doses given over about 8 months. Participants will be assigned to receive one of 2 Dosing Levels

- a higher or a lower level, with an equal chance of being assigned to either Dosing Level.

All participants will receive study drug; there is no placebo. This study was extended to allow participants to receive sapablursen for an additional 36 weeks following the initial 37-week treatment period.
