WARNING - MALIGNANCY Chronic immunosuppression with this purine antimetabolite increases risk of malignancy in humans. Reports of malignancy include post-transplant lymphoma and hepatosplenic T-cell lymphoma (HSTCL) in patients with inflammatory bowel disease. Physicians using this drug should be very familiar with this risk as well as with the mutagenic potential to both men and women and with possible hematologic toxicities. Physicians should inform patients of the risk of malignancy with AZASAN. See WARNINGS.
AZASAN®, an immunosuppressive antimetabolite, is available in tablet form for oral administration.
AZASAN is indicated as an adjunct for the prevention of rejection in renal homotransplantation. It is also indicated for the management of active rheumatoid arthritis to reduce signs and symptoms.
AZASAN is indicated as an adjunct for the prevention of rejection in renal homotransplantation. Experience with over 16,000 transplants shows a 5-year patient survival of 35% to 55%, but this is dependent on donor, match for HLA antigens, anti-donor or anti-B-cell alloantigen antibody, and other variables. The effect of azathioprine on these variables has not been tested in controlled trials.
AZASAN is indicated for the treatment of active rheumatoid arthritis (RA) to reduce signs and symptoms. Aspirin, non-steroidal anti-inflammatory drugs and/or low dose glucocorticoids may be continued during treatment with AZASAN. The combined use of azathioprine with disease modifying anti-rheumatic drugs (DMARDs) has not been studied for either added benefit or unexpected adverse effects. The use of AZASAN with these agents cannot be recommended.

A randomized trial of methotrexate versus azathioprine for severe atopic eczema. [2011.08]
BACKGROUND: Patients with severe atopic eczema frequently require systemic treatment to control their disease. Methotrexate and azathioprine are proposed as off-label treatment options, but direct comparisons are lacking. OBJECTIVES: We sought to compare the efficacy and safety of methotrexate versus azathioprine in adults with severe atopic eczema... CONCLUSION: Both treatments achieved clinically relevant improvement and were safe in the short term. Methotrexate and azathioprine are appropriate options for the treatment of severe atopic eczema.

A pragmatic randomized controlled trial of thiopurine methyltransferase genotyping prior to azathioprine treatment: the TARGET study. [2011.06]
AIM: To conduct a pragmatic, randomized controlled trial to assess whether thiopurine methyltransferase (TPMT) genotyping prior to azathioprine reduces adverse drug reactions (ADRs)... CONCLUSION: Our work supports the strong evidence that individuals with TPMT variant homozygosity are at high risk of severe neutropenia, whereas TPMT heterozygotes are not at increased risk of ADRs at standard doses of azathioprine.
Steroids and azathioprine in the treatment of IgA nephropathy. [2011.06]
AIM: IgA nephropathy (IgAN) is a very common glomerulonephritis among young adults, but the best therapeutic approach has not been fully elucidated. This study evaluated the effect of two different treatment regimes in IgAN, steroids alone or in combination with azathioprine... CONCLUSIONS: Both, steroid treatment alone and steroids in combination with azathioprine seem to be effective in reducing the severity of proteinuria and stabilizing renal function in IgAN. Patients who do not respond to steroids may have a better response with the combination of steroids and azathioprine.

LCP-Tacro vs. Azathioprine for the Treatment of Autoimmune Hepatitis [Completed]
An open-label, multi-center, prospective, randomized study to evaluate the efficacy, safety

with prednisone, for the treatment of autoimmune hepatitis (AIH).
Imuran (Azathioprine) Dose-Ranging Study in Crohn's Disease [Terminated]
The purpose of this study is to identify an optimal weight based dose of azathioprine that
is safe and effective in the treatment of subjects with active Crohn's disease requiring
treatment with corticosteroids, and for maintaining remission in those subjects.
Correlation of Genetic Polymorphism of Azathioprine Metabolizing Enzymes and Correlation to Clinical Adverse Effects [Completed]
Azathioprine (AZA) has long been used in dermatology in treating autoimmune bullous
dermatoses and generalized eczematous disorders as well as some photodermatoses. Its
metabolic process inside human body and its side effects relies on genetic polymorphism of
some enzymes such as thiopurine s-methyltransferase (TPMT) and inosine triphosphate
pyrophosphatase gene (ITPA). This study aims to analyze the relative contribution of TMPT
and ITPA mutations to the development of toxicity induced by AZA treatment and to detect the
correlation of the genetic polymorphism.
Preventing Postoperative Relapse in Crohn's Disease Patients at Risk: Azathioprine Versus Mesalazine [Completed]
This study aims to compare azathioprine versus mesalazine tablets for the prevention of

Azathioprine in the Prevention of Ileal Crohn's Disease Postoperative Recurrence. [Terminated]
The objective of this study is to evaluate if in the prevention of postoperative recurrence
of ileal Crohn's disease immediate initiation of azathioprine postoperatively is superior to
delayed (6- 12 mths.) introduction of azathioprine upon disease recurrence assessed by
endoscopic criteria. The primary endpoint, disease recurrence, encompasses symptomatic and
surgical recurrence as well as severe endoscopic lesions at the final, 2 year, assessment.
