Single-arm, open-lable, multicentre study to compare the efficacy and safety of atorvastatin, acetylcysteine plus danazol with danazol monotherapy in patients with corticosteroidresistant/relapsed ITP.
Immune thrombocytopenia (ITP) is a severe bleeding disorder. Approximately 2/3 of patients achieve remission from first-line therapies. However, the underlying mechanism of corticosteroid-resistant or relapsed ITP is not well understood; thus, treatment remains a great challenge. Atorvastatin was shown to enhance bone marrow endothelial cell function and N-acetylcysteine (NAC) was shown to inhibit PLT binding to endothelial cell.
A multicentre prospective study was performed in non-splenectomized ITP patients who were either resistant to a standard dose of corticosteroids or had relapsed. Patients were randomized to atorvastatin, acetylcysteine plus danazol with danazol monotherapy group. Platelet count, bleeding and other symptoms were evaluated before and after treatment. Adverse events are also recorded throughout the study, in order to compare the efficacy and safety of atorvastatin, acetylcysteine plus danazol with danazol monotherapy in patients with corticosteroid-resistant/relapsed ITP.

Exclusion Criteria:
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.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
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.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
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.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
