About this trial

PANTHER-GI Pilot Study will assess the feasibility of a full-scale multicentre cohort management study evaluating the safety of a standardized strategy for resuming direct oral anticoagulants (DOACs) after major DOAC-related gastrointestinal (GI) bleeding among patients at moderate to high risk of re-bleeding and thrombosis. A parallel registry will assess whether eligible patients who are not enrolled in the PANTHER-GI Pilot Study are systematically different than enrolled patients and to explore barriers to enrolment.

Eligibility criteria

Qualifiers

Male or female subjects aged 18 years or older

Hospitalized with acute major non-variceal GI bleeding (defined as per ISTH criteria) while receiving OAC therapy (warfarin or DOAC).

OAC therapy discontinued for current acute GI bleed and not yet resumed

Ongoing indication for long-term anticoagulation of atrial fibrillation (moderate to high risk of stroke/systemic embolism with CHA2DS2VASc score of 3 or higher) or VTE (as per clinical care team)

Disqualifiers

Mechanical heart valve

VTE in the context of major transient risk factor and completed 3 months of treatment

GI bleeding managed surgically (e.g. gastrectomy, colectomy)

Active or previously treated gastrointestinal cancer

Trial design

Treatments tested in this trial

  • Restart DOAC within 7 days of clinical hemostasis after GI bleeding
  • Restart DOAC between 7 to 14 days of clinical hemostasis after GI bleeding
