About this study

This is a research study to compare the efficacy of aspirin (acetylsalicylic acid) and pneumatic compression devices versus enoxaparin (also known as Lovenox) and pneumatic compression devices in preventing deep vein thrombosis in patients with pelvic and lower extremity malignant tumors and undergoing surgery. Pneumatic compression devices are also known as sequential compression devices and are inflatable compression sleeves that are placed around patient's legs to reduce the risk of clot formation deep vein thrombosis. Pneumatic compression devices are made of a soft material that wraps around the lower leg and periodically squeeze the calf. A deep vein thrombosis is a blood clot. Most hospitalized patients wear these as a preventive measure. Pneumatic compression devices alone are not sufficient to prevent deep vein thrombosis formation. Therefore, medicines, such as aspirin and enoxaparin are utilized. Both drugs are used for prevention, but there are no studies in patients with musculoskeletal tumors which have determined whether one drug is better than another. The knowledge gained from this study will determine whether aspirin and pneumatic compression devices is the same or better than enoxaparin and pneumatic compression devices in preventing deep vein thrombosis in this patient population and may result in fewer wound and bleeding complications

Read the detailed description

PRIMARY OBJECTIVES:

  1. To perform a randomized prospective study to determine efficacy of acetylsalicylic acid (ASA)+pneumatic compression device (PCD) prophylaxis compared to low-molecular weight heparin (LMWH)+PCD in patients undergoing orthopaedic procedures for musculoskeletal neoplasms (MSN) of the pelvis and lower extremity.

II. To prove that ASA+PCD is clinically equivalent to or better than LMWH+PCD in providing deep vein thrombosis (DVT) prophylaxis in this patient population and results in fewer major bleeding complications.

III. To measure rates of postoperative DVT and pulmonary embolism (PE) as primary outcomes.

SECONDARY OBJECTIVES:

  1. To measure secondary outcomes including rates of readmission, reoperation, bleeding complications (including hematoma formation and prolonged wound drainage), and death.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive acetylsalicylic acid orally (PO) twice daily (BID) and wear PCD on days 1-28 after surgery.

ARM II: Patients receive enoxaparin subcutaneously (SC) once daily (QD) and wear PCD on days 1-28 after surgery.

After completion of study treatment, patients are followed up at 2 weeks, 6 weeks, and 3 months.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • acetylsalicylic acidDrug

    Also called ASA, Ecotrin, Empirin, Extren

    325 mg twice a day

  • enoxaparinDrug

    Also called Enoxaparin Sodium, Lovenox

    40 mg once daily

  • PCDDevice

    Also called thromboembolism prophylaxis, Flowtron calf compression

    Wear PCD (Flowtron calf compression). Patients will continue to use PCDs for the duration of their hospitalization. If patients refuse to wear the PCDs, they will be withdrawn from the study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. DVT Incident Rate

    This study will test if the ASA+PCD treatment group has a DVT rate (P1) not more than the DVT rate of the LMWH+PCD treatment group (P0) using a one sided test for these two proportions. Statistical significance will be defined as p < 0.05.

    Measured: Up to 3 months

Secondary outcomes (6)
  1. Pulmonary Embolism Rate

    Measured: Up to 3 months

  2. Development of Other Complications (Including Bleeding Complications)

    Measured: Up to 3 months

  3. Readmission Rate to Hopsital

    Measured: Up to 3 months

  4. Hematoma Formation

    Measured: Up to 3 months

  5. Excessive Wound Drainage

    Measured: Up to 3 months

  6. Death Rate

    Measured: Up to 3 months

Questions about this trial

What is this clinical trial studying?

A study testing acetylsalicylic acid, enoxaparin and PCD in people with Bone Metastases and Musculoskeletal Cancer, run by Ohio State University Comprehensive Cancer Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 4 Jul 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

DVT Incident Rate (time frame: Up to 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Dec 2018.
