TB-500 corresponds to the active region of Thymosin Beta-4, a naturally occurring 43-amino-acid protein involved in regulating the actin cytoskeleton
Other etiologies, such as metformin-induced lactic acidosis and infection, were ruled out with additional testing (a lactic acid level of 1 mmol/l, no signs of acute pancreatitis in CT scan, no signs of pneumonia in a chest X-ray)
Moreover, combination therapies have demonstrated significant advantages, such as Novo Nordisks CagriSema (semaglutide + cagrilintide), which shows superior glycemic control and weight reduction effects compared to semaglutide alone, demonstrating that combination therapy can achieve more than the sum of its parts while reducing side effects
It is contraindicated in individuals with a history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2, as well as those with a family history of these conditions
Similarly, combination with other pro-regenerative peptides such as TB-500 may provide complementary mechanisms supporting tissue repair through distinct pathways
