Introduction to Sodium Iodide I-131
Sodium Iodide I-131 is a radiopharmaceutical widely used in nuclear medicine for diagnostic and therapeutic purposes, particularly in the management of thyroid conditions. Here, we will delve into the current state of clinical trials, market analysis, and future projections for this drug.
Clinical Trials and Applications
Diagnostic Uses
Sodium Iodide I-131 is primarily used for the radioactive iodide (RAI) uptake test to evaluate thyroid function and to localize metastases associated with thyroid malignancies. It is essential for assessing thyroid function, differentiating between hypo- and hyperthyroidism, and evaluating thyroid cancer and metastases[4].
Therapeutic Uses
In therapeutic contexts, Sodium Iodide I-131 is used to treat hyperthyroidism and certain types of thyroid cancer. It has also shown promise in gene therapy strategies, particularly in non-thyroidal tumors, where the sodium iodide symporter (NIS) gene is transferred to enable radioiodine accumulation and subsequent tumor reduction[1].
Ongoing and Completed Trials
Several clinical trials have explored the efficacy and safety of Sodium Iodide I-131 in various settings. For instance, a phase 1 trial involving the use of the measles virus expressing the NIS gene (MV-NIS) in combination with I-131 showed promising results in treating prostate cancer and myeloma. However, the uptake was modest and not seen in all lesions[1].
A phase 2 study conducted at the University of Arkansas has recently been completed, although the data has not yet been published. These trials highlight the ongoing research into the expanded use of Sodium Iodide I-131 in cancer therapy.
