Is this trial a fit for you?

Likely a good fit

Adult women 18 years and older who are currently menstruating and have anaemia (Hb < 120 g/L by finger-prick test).

Probably not a fit

Women who do not respond to TXA or who have contraindications may not experience additional benefit.

What this trial studies

This randomized, phase 3 trial compares tranexamic acid 500 mg plus standard iron and vitamin supplementation to iron and vitamins alone for treating anaemia in adult women who are currently menstruating. Participants are eligible if they are 18 or older, have regular periods, and have anaemia confirmed by a finger-prick Hb test. The study aims to determine whether TXA can improve haemoglobin levels and reduce menstrual blood loss when used alongside standard care. The trial will be conducted at multiple international sites with in-person follow-up visits to monitor safety and effectiveness. Outcomes may inform future prescribing for managing anaemia in reproductive-age women.

Why it matters

Potential benefit: If successful, the combination could more effectively correct anaemia and improve daily functioning and quality of life for menstruating women.

How similar studies have gone: Prior use of tranexamic acid for heavy menstrual bleeding supports safety and potential benefit, but this specific combination with iron and vitamins in anaemia is being tested to confirm effectiveness.
