Introduction to Thioguanine
Thioguanine, an antimetabolite medication, is primarily used in the treatment of various types of leukemia, including acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML). It functions by inhibiting the synthesis and function of DNA and RNA, thereby arresting the growth of cancer cells[2][3][5].
Clinical Trials Update
The TEAM Study
One significant clinical trial involving thioguanine is the TEAM Study (Thiopurine EnhAnced Maintenance therapy). This Phase 1-2 study aims to explore the feasibility of using 6-thioguanine (6TG) as a supplement to the standard maintenance therapy of ALL and lymphoblastic non-Hodgkin’s lymphoma. The trial combines 6TG with methotrexate (MTX) and 6-mercaptopurine (6MP) to assess whether this combination can achieve higher DNA-thioguanine nucleotide (TGN) levels and enhance the effect of 6MP. The study also focuses on describing toxicities, hematology, and thiopurine metabolite levels during this combination therapy[1].
Safety and Toxicity Monitoring
In the TEAM Study, the frequency of controls was increased to monitor any toxicities early, especially myelo- or hepatotoxicity. The dosing of 6MP and MTX was adjusted according to the NOPHO therapy guidelines in case of such toxicities. The administration of 6TG was either withheld or reduced depending on the severity of the toxicity[1].
Thioguanine in Inflammatory Bowel Disease
Another area of clinical research involves the use of thioguanine in the treatment of inflammatory bowel disease (IBD). A retrospective cohort study examined the safety, effectiveness, and 12-month drug survival of thioguanine in thiopurine-naïve patients with IBD. The study found that thioguanine was clinically effective in 53% of patients at 12 months, with an acceptable safety profile and a low cessation rate due to adverse events. This suggests that thioguanine could potentially be used as a first-line maintenance therapy for IBD instead of conventional thiopurines[4].
