MedDRA Classification |
E.1.2 Medical condition or disease under investigation |
E.1.2 | Version | 9.1 |
E.1.2 | Level | LLT |
E.1.2 | Classification code | 10043551 |
E.1.2 | Term | Thrombocytopaenia |
|
E.1.3 | Condition being studied is a rare disease | Yes |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
to test the hypothesis that eltrombopag, at the dose of 50 or 75 mg/daily for up to 6 weeks, increases platelet count in MYH9RD patients with less than 50x10 exp9 platelets/L. |
|
E.2.2 | Secondary objectives of the trial |
a) to test the hypothesis that eltrombopag reduces bleeding tendency, measured with a bleeding scale; b) to evaluate in vitro function of platelets produced during eltrombopag therapy in patients responding to this drug; c) to evaluate safety and tolerability of eltrombopag in patients with MYH9RD |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Age ≥ 16 years - Confirmed diagnosis of MYH9RD - Average platelet count for the previous year less than 50x10 exp9/L - Written informed consent |
|
E.4 | Principal exclusion criteria |
- Diseases known to involve the risk of thromboembolic events (e.g. atrial fibrillation) - History of thrombosis within 1 year - Use of drugs that affect platelet function (including but not limited to, aspirin, clopidogrel or NSAIDS) or anti-coagulants - Females who are pregnant or nursing (a negative pregnancy test in required before enrollment of fertile women) - Formal refusal of any recommendation of a safe contraception - Alcohol or drug addiction - Altered renal function as defined by creatinine ≥ 20 mg/L - Any other disease or condition that by the advise of the responsible physician would make the treatment dangerous for the patient or would make the patient ineligible for the study, including physical, psychiatric, social and behavioral problems. HCV positivity and liver diseases will not be considered an exclusion criterion since a phase II study showed that eltrombopag was effective and safe in this patient population. |
