Incidence of Intracranial Hemorrhage in Glioma Patients With Venous Thromboembolism Converted From LMWH to Apixaban

December 1, 2022 updated by: Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins
Glioma patients with history of venous thromboembolism (VTE) treated on low molecular weight heparin (LMWH) and who decided with their physician to convert to Apixaban (oral drug) will be enrolled into our study and will collect data regarding recurrent VTE and Intracranial hemorrhage and the incidence of these events.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Primary Objectives To estimate the incidence of intracranial hemorrhage (ICH) in glioma patients with history of venous thromboembolism (VTE) after the conversion from low molecular weight heparin (LMWH) injections to oral Apixaban.

Secondary Objective To estimate the incidence of recurrent VTE in glioma patients with history of venous thromboembolism after the conversion from low molecular weight heparin (LMWH) injections to oral Apixaban.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Sampling Method

Probability Sample

Study Population

Patients greater than or equal to 18 years of age who have had a pathologically confirmed supra-tentorial primary brain tumor and a history of deep venous thrombosis (DVT) and/or pulmonary embolism (PE).

Description

Inclusion Criteria:

  • Patients must be 18 years of age or older;
  • Patients must have had a pathologically confirmed supra-tentorial primary brain tumor
  • Patients must have history of deep venous thrombosis (DVT) and/or pulmonary embolism (PE)
  • Patients must have been treated with low molecule weight heparin for ≥ 5 days
  • Patients must be able to provide written informed consent
  • Patients must have non contrast CT that is negative for intra-cranial bleed at least 5 days post initiation of LMWH and prior to initiation (within 7 days) of Apixaban
  • Must be decision by patient and his physician to convert to Apixaban

Exclusion Criteria:

  • Patients with a plan less than 6 months of anticoagulation for most recent DVT or PE
  • Patients with allergic reaction to Apixaban
  • Patients with active bleeding or high risk for bleeding contraindicating treatment with LMWH
  • Patients with planned surgery in the next 2 weeks
  • Patients previously treated with Apixaban
  • Patients requiring Acetylsalicylic Acid (ASA) greater than165 mg/day at enrollment
  • Patients requiring dual anti-platelet therapy (ASA plus clopidogrel or ASA plus ticlopidine) at enrollment.
  • Subjects with transition for dual anti-platelet therapy or monotherapy prior to enrollment will be eligible for the study
  • Patients who are compulsorily detained for treatment of either a psychiatric or physical (e.g. infectious disease) illness
  • Any condition, which in the opinion of the investigator, would put the subject at an unacceptable risk from participating in the study
  • Any other medical, social, logistical, or psychological reason, which in the opinion of the investigator, would preclude compliance with, or successful completion of, the study protocol
  • Known active and clinically significant liver disease (e.g., hepatorenal syndrome)
  • Known bacterial endocarditis
  • Know uncontrolled hypertension: systolic blood pressure greater than 160 mm Hg or diastolic blood pressure greater than 100 mm Hg; (subjects who have a transient, higher blood pressure elevation associated with acute PE [upper limit: systolic blood pressure 200 mm Hg or diastolic blood pressure 100 mm Hg] may enter the study;) elevated blood pressure that is persistent 1 - 2 days after the index DVT or PE should be treated according to local guidelines

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Cohort Apixaban

patients who have switched from low molecular weight heparin (LMWH) to apixaban at the recommended dose of the treating physician.

FDA approved dose 10 mg twice daily (BID) for 7 days followed by 5 mg PO BID OR physician prescribed dose
Other: Observation of ICH and VTE
The treating physician will initiate and prescribe the apixaban, the protocol will only observe and record intracranial pressure (ICP) and VTE incidences.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Intracranial Hemorrhage (ICH) event incidence rate
Time Frame: 1 year
Observe subject to determine the incidence of ICH during standard of care (SOC) observations.
1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Deep venous thromboembolism (VTE) event incidence rate
Time Frame: 1 year
Observe subject to determine the incidence of VTE during SOC observations.
1 year

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
