Trial Information

Diindolymethane: Anti-proliferation Agent in Thyroid Disease—Non-surgical Protocol

Inclusion Criteria:

- Adults diagnosed with abnormalities of the thyroid gland suspicious for benign
adenoma, or goiterous changes.

Exclusion Criteria:

- Patients who are pregnant, attempting to conceive, or lactating will be excluded due
to possible deleterious effects of treatment on fetus/infant. Patients taking oral
contraceptives, estrogen therapy, tamoxifin or those with a history of breast cancer
will be excluded. Patients with liver disease and those taking statins for
hypercholesterolemia will also be excluded to decrease the potential for possible
liver toxicity. Any patient with elevated liver enzymes on pretreatment blood
screening will be excluded from study participation. Patients with serious systemic
diseases such as renal failure, diabetes, blood dyscrasia, coagulopathy, and
non-optimized cardiopulmonary disease will be excluded due to the possibility of
confounding blood tests screening for toxicity.
