    Sobetirome (GC-1) Dosage Guide: Protocols, Calculator & Safety

    Everything you need to know about Sobetirome (GC-1) dosing: protocols, safety, and where to buy.

    Half-Life

    Not established in humans; no peer-reviewed human pharmacokinetic study has been published, and the phase 1 program results were not reported in the peer-reviewed literature (PMID: 19002578)

    Administration Routes

    Oral

    Side Effects & Safety

    No peer-reviewed human safety data. The animal record contains a specific warning: GC-1 acted as a strong mitogen in rats, inducing hepatocyte proliferation in the absence of tissue injury and massive pancreatic acinar cell proliferation (PMID: 16574785). Thyroid receptor beta agonism as a class suppresses thyroid stimulating hormone, which was demonstrated in the rat dose-response work (PMID: 10965874). The cardiac sparing seen in rats and monkeys is relative, not absolute; tachycardia appeared at higher exposure in rats (PMID: 14701670).

    Contraindications

    Mechanism-based, since no human trial has defined contraindications. Thyroid hormone receptor agonism is inappropriate for anyone with existing hyperthyroidism, atrial fibrillation or unstable coronary disease, and it suppresses thyroid stimulating hormone and disturbs thyroid function testing (PMID: 10965874). The rat liver and pancreas proliferation findings argue against use by anyone with liver disease or pancreatic disease (PMID: 16574785). No human pregnancy, lactation or pediatric data exist. Anyone taking levothyroxine or antithyroid medication would have their treatment monitoring confounded.
