Abstract

Insights

Cabozantinib offers improved overall survival for advanced hepatocellular carcinoma (HCC) patients post-sorafenib treatment. However, this study found cabozantinib not to be a cost-effective second-line therapy in the US at current pricing.

Area of Science:

  • Oncology
  • Health Economics
  • Pharmacoeconomics

Background:

  • Limited treatment options exist for advanced hepatocellular carcinoma (HCC) progressing after sorafenib.
  • Cabozantinib demonstrated improved overall survival (OS) in the CELESTIAL trial for such patients.
  • This study evaluates the cost-effectiveness of cabozantinib as a second-line HCC treatment from a US healthcare perspective.

Purpose of the Study:

  • To assess the cost-effectiveness of cabozantinib versus placebo plus best supportive care for second-line treatment of advanced HCC.
  • To determine the incremental cost-effectiveness ratio (ICER) for cabozantinib in this patient population.

Main Methods:

  • Cost and utility data were extracted from the CELESTIAL trial.
  • The incremental cost-effectiveness ratio (ICER) was calculated as cost per quality-adjusted life year (QALY) gained.
  • Sensitivity and cost-threshold analyses were performed.

Main Results:

  • The base-case analysis yielded an ICER of $1,040,675 per QALY gained for cabozantinib.
  • Overall survival (OS) from the CELESTIAL trial was the most influential factor on the ICER.
  • No scenarios in sensitivity analyses demonstrated cabozantinib to be cost-effective; a price reduction to $50/pill was estimated as necessary.

Conclusions:

  • Cabozantinib is not a cost-effective second-line therapy for advanced HCC in the United States at its current cost.
  • Despite improving OS, the high cost of cabozantinib limits its value in this treatment setting.

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...

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.

Buffer Effectiveness02:19

Buffer Effectiveness

Buffer solutions do not have an unlimited capacity to keep the pH relatively constant . Instead, the ability of a buffer solution to resist changes in pH relies on the presence of appreciable amounts of its conjugate weak acid-base pair. When enough strong acid or base is added to substantially lower the concentration of either member of the buffer pair, the buffering action within the solution is compromised.
The buffer capacity is the amount of acid or base that can be added to a given volume...

Framing Effects

Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Sample Preparation for Analysis: Advanced Techniques

Accurate analysis of complex samples often requires advanced preparation techniques to achieve reliable and reproducible results. Samples containing inorganic or organic materials can be challenging to dissolve or decompose effectively. Standard sample preparation methods include acid digestion, fusion, dry ashing, and wet digestion.
Acid digestion with strong acids is commonly used to dissolve inorganic materials that are insoluble (do not dissolve) in water. This method can be useful for...

Biological Effects of Radiation02:59

Biological Effects of Radiation

All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...
