DS-9231 in Intermediate-risk (Sub-massive) Acute Pulmonary Embolism (PE)

Phase 2
Withdrawn
Conditions
Pulmonary Embolism
Interventions
Drug: Placebo
Registration Number
NCT03316729
Lead Sponsor
Daiichi Sankyo
Brief Summary

The primary objective of this study is to evaluate safety and initial effectiveness of DS-9231 when taken together with current standard of care. Evaluation will be done with low, medium and then high doses of DS-9231 versus placebo, in participants with medium-risk acute pulmonary embolism.
