Study summary

Hemoptysis is one of the serious complication of many pulmonary diseases. Upto now, there is no proven medical treatment in recurrence of hemoptysis. The investigators will conduct a randomized, placebo controlled trial of tranexamic acid, which can reduce the recurrence of hemoptysis.

Inclusion criteria

  • age: >=20 and \<=75
  • ER visit or admission for hemoptysis
  • no evidence of hemoptysis on screening

Exclusion criteria

Exclusion Criteria:

  • anticoagulation treatment
  • Cr >= 2.0 mg/dL or urinary protein >= 2+ or who received renal replacement treatment
  • hepatic failure: total >= 1.5 mg/dL or or ALT >= 1.5 of upper normal limit level
  • to tranexamic acid
  • pregnant woman
  • fertile female who don't use
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 7, 2014, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
