Toxicities will be described according to type and grade as frequencies. A list of all serious adverse events will be reported.
Efficacy outcomes will be reported using descriptive statistics of the efficacy endpoints. The primary outcome will be analysed using logistic regression. Overall survival (OS) will also be assessed, defined as the time from the data of the first dose of study medication to the date of death from any cause. OS will be estimated with the Kaplan-Meier method.

Summary
Brief summary
Allogeneic Stem Cell transplant (alloSCT) is a curative procedure for many blood disorders and involves the transplantation of donor blood cells into a compatible recipient. Engraftment is a key milestone of success of alloSCT and is measured by standard blood tests to ensure normal levels of blood cells as well as a specialised blood test to confirm this blood is being produced by donor tissue. Poor graft function (PGF) is a significant complication of alloSCT and results in poor blood cell production by engrafted donor tissue. Aplastic anaemia(AA) is an autoimmune disease that results in the body's own immune cells attacking the bone marrow (the organ that produces blood cells) resulting in decreased production of blood cells. The mechanisms leading to PGF and AA are similar. There is evidence that the bone marrow microenvironment, the ecosystem in which blood cells reside, is abnormal in both PGF and AA. Atorvastatin is an old drug that has been used to treat high cholestrol and N-acetyl-cysteine (NAC) has been used as an antioxidant to treat paracetamol overdose. There is evidence that atorvastatin and NAC may be able to reverse this microenvironment dysfunction in PGF and AA. This study is aimed at testing the efficacy and safety of atorvastatin and NAC in the treatment of PGF and relapsed/refractory Aplastic anaemia.
