Haemophilia Carriers clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Evaluation of Menses in Congenital Bleeding Disorders

MEVA-3

Start date: February 2010
Phase: N/A
Study type: Observational

Menorrhagia is the term used to define excessive menstrual blood losses, as often based on a subjective judgment of women. Many arbitrary values, expressed in milliliters of blood, have been proposed to define this symptom: 60 on each cycle has also been confirmed in our preliminary study on 87 healthy women. The quantitative determination of menstrual blood losses is nevertheless rarely performed, only in research settings. Although menorrhagia is a quite frequent symptom in healthy women apparently haemostatically competent in the fertile age (20-30%), its incidence becomes very high in women affected by congenital coagulation factors deficiency and (50-62.9%) inherited platelet defects, e.g. Glanzmann's Thromboasthenia (GT); also in von Willebrand Disease the bleeding symptom "menorrhagia" has an high prevalence (60-75%)(8); for GT an incidence of 90% has been reported. This explains the need for a study focused on the evaluation of menorrhagia in CBDs, addressed to answer to the following, still unsolved questions: 1. Definition of the entity of menstrual blood losses in women affected by CBDs 2. Elaboration of specific treatment schedules for each type of CBD 3. Impact of different specific treatment schedules on kinetic and entity of menstrual losses (how does treatment modify losses?).
