Insights

Lenvatinib, a kinase inhibitor, shows efficacy in advanced thyroid cancer by stabilizing disease. Careful management of side effects is crucial for successful treatment continuation and improved outcomes.

Area of Science:

  • Oncology
  • Pharmacology
  • Clinical Trials

Background:

  • Multitargeted kinase inhibitors (MKIs) offer a significant advancement in treating progressive, metastatic thyroid cancer.
  • Lenvatinib, an MKI, targets multiple receptors including VEGFR, FGFR, PDGFR, c-Kit, and RET, demonstrating efficacy in stabilizing disease.

Purpose of the Study:

  • To review the clinical efficacy and safety of MKIs in advanced thyroid cancer based on pivotal Phase III trials.
  • To discuss common adverse events associated with lenvatinib and strategies for their management, including dose modification.

Main Methods:

  • Review of pivotal Phase III clinical trials evaluating MKIs in advanced thyroid cancer.
  • Focus on data from a Japanese subanalysis of the SELECT trial and a post-marketing study in Japan.
  • Analysis of adverse events and management strategies for lenvatinib therapy.

Main Results:

  • Lenvatinib demonstrates efficacy in stabilizing previously progressive thyroid cancer, with potential overall survival benefits.
  • Adverse event profiles are similar to other MKIs and require careful monitoring and management.
  • Data from Japanese patient studies support lenvatinib's role in advanced differentiated thyroid cancer.

Conclusions:

  • Lenvatinib is a valuable treatment option for advanced differentiated thyroid cancer.
  • Effective management of adverse events through supportive care and dose adjustments is essential for treatment continuation.
  • MKIs represent a key therapeutic strategy for advanced thyroid cancer, necessitating a balanced approach to efficacy and safety.

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

The Thyroid Gland01:23

The Thyroid Gland

The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Functions of Thyroid Hormones

The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Extraction: Advanced Methods00:56

Extraction: Advanced Methods

Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...
