Clinical Studies – Targeting Acute and Chronic Thromboembolic Disorders

SELECT-D: A randomised control trial of Xarelto vs dalteparin in patients with active cancer

Background1

  • The risk of recurrent VTE is increased at least two-fold in patients with cancer compared to those without
  • For more than a decade, subcutaneous low-molecular weight heparin (LMWH) has been the standard of care

Objective1

  • To assess if an oral factor Xa inhibitor, Xarelto, would offer an alternative treatment for VTE in patients with cancer

Study design1

  • A multicentre, randomised, open-label, pilot trial in the United Kingdom to investigate patients with active cancer who had symptomatic PE, incidental PE or DVT. Patients were treated with either dalteparin or Xarelto
SELECT-D

Endpoints1

Primary efficacy outcome

  • VTE recurrence

Primary safety outcomes

  • Major bleeding
  • Clinically non-relevant bleeding

Key findings1

  • Over the course of 6 months fewer patients treated with Xarelto experienced a recurrent VTE compared to dalteparin (4% vs 11.0% respectively).
  • Only 54% of patients completed the 6-month duration of study with a median duration of treatment of 5.8 and 5.9 months for dalteparin and Xarelto respectively
  • 4% of patients receiving dalteparin had major bleeds compared with 6% of patients treated with Xarelto.
  • Incidence of fatal bleeding was the same in both groups (0.5%)
  • 7 patients receiving dalteparin experienced CRNMB compared with 25 patients receiving Xarelto (3-fold relative increase).
  • Overall survival at 6 months was 75% for Xarelto (95% CI 69%–81%) and 70% for dalteparin (95% CI 63%–76%).

BID, twice daily; ECOG PS, Eastern Cooperative Oncology Group performance status; LMWH, low-molecular weight heparin; OD, once daily; SC, subcutaneous; VTE, venous thromboembolism;

*Active cancer was defined as a diagnosis of cancer (other than basal-cell or squamous-cell skin carcinoma) within the previous 6 months, recurrent or metastatic cancer, or cancer not in complete remission.
