Brief summary

This trial seeks to evaluate a management strategy after the acute treatment duration (≥ 3 months of therapeutic anticoagulation) for patients with cancer and catheter-related upper extremity deep vein thrombosis (DVT).

Detailed description

The aim of the STREAM-Line Trial is to demonstrate that the STREAM-Line management strategy is safe after the acute treatment duration (≥ 3 months of therapeutic anticoagulation) in patients with cancer and catheter-related upper extremity DVT. Upon enrollment and during follow-up, patients will be managed with a prophylactic dose of apixaban (2.5 mg orally twice daily) as long as either a central venous catheter (CVC) or active cancer is present (STREAM-Line management strategy). Apixaban will be stopped at the time of CVC removal and when cancer is in remission. Day 90±14 and Day 180+14 follow-up visit procedures will be done by phone call or in person.

Interventions

DRUGApixaban

Apixaban is Health Canada approved for routine treatment and secondary prevention of VTE. Upon enrollment and during follow-up, patients will be managed with a prophylactic dose of apixaban (2.5 mg orally twice daily) as long as either a CVC or active cancer is present. Apixaban will be stopped at the time of CVC removal and when cancer is in remission. Patients will be instructed to contact the study team when their CVC is removed (to determine if apixaban should be continued, based on cancer status at the time), or any thrombotic or bleeding concerns were to occur in between visits. The investigators will record loss to follow-up, drop out, or death during the study.

Inclusion criteria

1. Adult patients (≥ 18 years old) with active cancer, defined as cancer (other than localized non-melanoma skin cancer) diagnosed or treated within 6 months, or the presence of metastatic, recurrent, or progressive malignancy, ongoing anticancer therapy, or hematological malignancy not in complete remission. 2. Objectively confirmed catheter-related upper extremity DVT and treated with any standard therapeutic anticoagulation (including LMWH dose reduction to 75% after the first month) for at least 3 months. 3. Able and willing to provide informed consent.

Exclusion criteria

1. Active bleeding or other reasons for which anticoagulation is contraindicated. 2. Other indications requiring ongoing therapeutic dose of anticoagulation as deemed necessary by treating physicians (such as atrial fibrillation, mechanical heart valve, etc.). 3. Anticoagulation has been permanently stopped or reduced to prophylactic dose prior to enrollment for any reasons, except for participants who were transitioned to apixaban dosing regimen consistent with the protocol (2.5 mg twice daily) for ≤ 3 days . 4. Known contraindication for apixaban, such as allergy, hypersensitivity, or pregnancy. 5. Concomitant use of strong inhibitors or inducers of both cytochrome P450 3A4 (enzyme) and P-glycoprotein.

Secondary

MeasureTime frameDescription
New/recurrent symptomatic catheter-related upper extremity Deep Vein Thrombosis (DVT).3 months and 6 monthsNew/recurrent symptomatic catheter-related upper extremity DVT.
New incidental Venous Thromboembolism (VTE)3 months and 6 monthsNew incidental VTE (PE or upper or lower extremity DVT), defined as VTE diagnosed on imaging studies obtained not for concern of VTE, such as cancer staging scans.
New Deep Vein Thrombosis (DVT)3 months and 6 monthsNew/recurrent any distal upper or lower extremity DVT or subsegmental PE.
Superficial vein thrombosis of upper or lower extremities3 months and 6 monthsSuperficial vein thrombosis of upper or lower extremities
New unusual site Venous Thromboembolism (VTE)3 months and 6 monthsNew unusual site VTE (such as splanchnic vein, cerebral vein, or gonadal vein thrombosis).
Major Venous Thromboembolism (VTE) and Major bleeding Rate3 monthsRates of new/recurrent symptomatic major VTE and major bleeding at 3 months.
Arterial thromboembolic events3 months and 6 monthsArterial thromboembolic events (objectively confirmed), including myocardial infarction, stroke, peripheral arterial disease, or other systemic arterial embolism.
All-cause mortality3 months and 6 monthsAll-cause mortality
Correlative biomarkers6 monthsCorrelative biomarkers at 6 months, while the exact list of correlative biomarkers is to be determined at the time of study completion, examples include D-dimer, P-selectin, prothrombin F1+F2, thrombin generation, etc.
