Marc Carrier: Proud to Share the Results of the WAVe Study

Marc Carrier, Professor at Ottawa Hospital Research Institute, shared on LinkedIn:

”Proud to share the results of the WAVe Study published in AjHematology

In this Canadian multicenter collaboration across six academic centers, we evaluated weight-adjusted dalteparin dosing (up to 33,000 IU/day) in patients with cancer-associated thrombosis weighing >90 kg.

Despite early study termination due to recruitment challenges — following the rapid uptake of DOACs for VTE and updated ISTH guidance removing the upper weight limit for DOAC use — our findings remain clinically relevant:

  • Major bleeding: 5.3% at 30 days
  • Recurrent VTE: 1.2% at 30 days
  • No significant drug accumulation (based on anti-Xa levels)

These results suggest that weight-adjusted LMWH remains a safe and effective option for selected patients with cancer and obesity, particularly those at higher bleeding risk or with contraindications to DOACs.”
