Can a simple drug cut blood loss in kids with CP after hip surgery?
NCT ID NCT07672158
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase III trial tests whether giving tranexamic acid continuously for 24 hours after hip surgery can reduce blood loss in non-ambulatory children with cerebral palsy. About 52 children aged 4 to 16 will be randomly assigned to receive either the drug or a placebo. The goal is to see if the drug lowers the need for blood transfusions and improves recovery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tranexamic acid
- What this could lead to
- If it works, this could provide a safe way to reduce blood loss and the need for blood transfusions in children with cerebral palsy after major hip surgery.
- What could go wrong
- This is a small, early-stage trial with only 52 children, so results may not apply to everyone. There is also a risk of seizures, which the study will monitor closely.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Children (aged 4 to 16 years) * Diagnosis of cerebral palsy (CP). CP is an umbrella term under which many specific diagnoses are captured, and the clinical team at the study institution operates a comprehensive referral network to ensure patients with any relevant diagnoses are included. * Gross Motor Function Classification System (GMFCS) levels IV and V, with substantial hip displacement (\>40% migration percentage per Australian Hip Surveillance Guidelines (Wynter M, Gibson N, Kentish M, Love S, Thomason P, Willoughby K, et al. Australian hip surveillance guidelines for children with cerebral palsy 2014. Australian Academy of Cerebral Palsy and Developmental Medicine. 2014.)), who are on the waitlist for bilateral proximal femoral varus derotational osteotomy (VDRO) +/- unilateral or bilateral pelvic osteotomy. Exclusion Criteria: * Haematological disorder (defined as an active genetic or acquired bleeding disorder) * Known hypersensitivity to tranexamic acid (TXA) * Children with promyelocytic leukaemia being treated with oral tretinoin will be excluded from the trial because combination with TXA has resulted in fatal thrombotic complications * Known coagulation defect * Known renal disorder (moderate to severe as per study institution guidelines)
