Kidney Failure, Chronic Drug: Tinzaparin Drug: Unfractionated Heparin Drug: Placebo (for Tinzaparin) Drug: Placebo (for Unfractionated Heparin) Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: Intermittent HEMOdialysis Anticoagulation With TINzaparin Versus Unfractionated Heparin: A Pilot Multicentre Randomized Controlled Trial (HEMO-TIN Trial)
