Abstract

Insights

Anlotinib shows promising results for advanced medullary thyroid carcinoma (MTC). This Phase II trial indicates durable antitumor activity and a manageable safety profile for patients with metastatic MTC.

Area of Science:

  • Oncology
  • Pharmacology
  • Clinical Trials

Background:

  • Medullary thyroid carcinoma (MTC) has a poor prognosis with limited treatment options for advanced or metastatic disease.
  • Anlotinib has demonstrated potential antitumor effects in preclinical and Phase I studies for MTC.
  • This Phase II trial aimed to validate anlotinib's efficacy in patients with advanced or metastatic MTC.

Purpose of the Study:

  • To confirm the antitumor activity of anlotinib in patients with advanced or metastatic medullary thyroid carcinoma.
  • To evaluate the progression-free survival (PFS) in patients treated with anlotinib.
  • To assess the safety and tolerability of anlotinib in this patient population.

Main Methods:

  • A Phase II clinical trial involving patients with unresectable locally advanced or metastatic MTC.
  • Anlotinib was administered orally at 12 mg daily (2 weeks on/1 week off) until disease progression or unacceptable toxicity.
  • The primary endpoint was progression-free survival (PFS), with dose adjustments based on toxicity.

Main Results:

  • Fifty-eight patients were treated with anlotinib; PFS has not yet been reached.
  • Investigator assessments showed a partial response in 56.9% of patients, with an 85.5% PFS rate at 48 weeks.
  • Forty-five patients achieved a ≥50% decrease in serum calcitonin; common adverse events included hand-foot syndrome and hypertriglyceridemia.

Conclusions:

  • Anlotinib exhibits durable antitumor activity in patients with advanced or metastatic medullary thyroid carcinoma.
  • The drug presents a manageable adverse event profile, supporting its potential as a therapeutic option.
  • Further investigation may solidify anlotinib's role in MTC treatment strategies.

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...

Overview of Advanced Functional Groups


Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.

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...
