Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

* More than 120 hours of pre-treatment with therapeutic doses of UFH, LMWH, or other anticoagulants
* An indication to continue treatment with therapeutic doses of an anticoagulant other than for VTE treatment prior to randomization (e.g., atrial fibrillation, mechanical heart valve, prior VTE)
* PE leading to hemodynamic instability (systolic BP <90 mmHg or shock).
* Acute ischemic or hemorrhagic stroke or intracranial hemorrhage, in the last 4 weeks preceding screening.
* Brain trauma, or cerebral or a spinal cord surgery or spinal procedures such as lumbar puncture or epidural/spinal anesthesia within 4 weeks of screening
* Need for aspirin in a dosage of more than 100 mg/day or, any other antiplatelet agent alone or in combination with aspirin
* Bleeding requiring medical attention at the time of randomization or in the preceding 4 weeks
* Planned brain, spinal cord, cardiac, vascular, major thoracic and/or major abdominal surgery in the 4 weeks following randomization

* Eastern Cooperative Oncology Group (ECOG) performance status of 3 or 4 at screening
* Life expectancy of <3 months at randomization
* Calculated creatinine clearance (CrCl) <30 mL/min at the screening visit
* Platelet count <50,000/ mm3 at the screening visit
* Hemoglobin <8 g/dL at the screening visit
* Acute hepatitis, chronic active hepatitis, liver cirrhosis; or an alanine aminotransferase =3 times and/or bilirubin =2 times the upper limit of normal (ULN) at the screening visit in the absence of clinical explanation

* Women of child-bearing potential (WOCBP) who are unwilling or unable to use highly effective contraceptive measures during the study from screening up to 3 days after last treatment of dalteparin or 100 days after administration of abelacimab
* Sexually active males with sexual partners of childbearing potential must agree to use a condom or other reliable contraceptive measure up to 3 days after last treatment of dalteparin or 100 days after administration of abelacimab
* Pregnant or breast-feeding women
* History of hypersensitivity to any of the study drugs (including dalteparin) or its excipients, to drugs of similar chemical classes, or any contraindication listed in the label for dalteparin
* Subjects with any condition that in the judgement of the Investigator would place the subject at increased risk of harm if he/she participated in the study
* Use of other investigational (not-registered) drugs within 5 half-lives prior to enrollment or until the expected pharmacodynamic effect has returned to baseline, whichever is longer.
