Primary Outcome Measures:
  • Number of eligible and recruited patients (target recruitment rate of 30% of eligible patients) over 12 months, and proportion of participants with recurrent VTEs during follow-up. [ Time Frame: 24 months ]

Secondary Outcome Measures:
  • Completion of trial protocol [ Time Frame: 24 months ]
  • Quality of life [ Time Frame: 24 months ]
  • Symptom assessment during the study [ Time Frame: 24 months ]
    Toxicities, including bleeding events and VTEs, will be assessed during the 6 month trial treatment period.

  • Attitudes of clinicians and patients to extended treatment with LMWH [ Time Frame: 24 months ]
    Attitudes of clinicians and patients to extended treatment with LMWH will be assessed through clinician focus groups and qualitative interviews with patients and carers.

Estimated Enrollment: 200
Study Start Date: March 2013
Estimated Study Completion Date: February 2015
Estimated Primary Completion Date: November 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: A: Continue treatment
Continue low molecular weight heparin (LMWH) at treatment dose according to body weight for further six months.
Drug: Low Molecular Weight Heparin (LMWH)
Participants randomised to Arm A will have already received LMWH (Fragmin®), tinzaparin (Innohep®) or enoxaparin (Clexane®) at treatment dose for six months off trial, and should continue the same drug at the same dose for a further six months on trial. No dose alterations are required unless clinically indicated.
Other Names:
  • Dalteparin (Fragmin®)
  • Tinzaparin (Innohep®)
  • Enoxaparin (Clexane®)
No Intervention: B: Discontinue treatment
Discontinue low molecular weight heparin (LMWH) once patient has received six months treatment following index VTE case.
