Abstract

Insights

Cabozantinib demonstrates improved progression-free survival, overall survival, and objective response rates in advanced renal cell carcinoma (RCC) patients previously treated with VEGFR-tyrosine kinase inhibitors. It shows promise as a leading second-line therapy and potentially in the first-line setting.

Area of Science:

  • Oncology
  • Pharmacology
  • Medical Science

Background:

  • Advanced renal cell carcinoma (RCC) treatments include VEGF/mTOR inhibitors and nivolumab.
  • Cabozantinib, a MET, VEGF, and AXL inhibitor, is FDA/EC-approved for advanced RCC post-VEGFR-TKI therapy.
  • This review covers cabozantinib's preclinical data, pharmacokinetics, and clinical outcomes in advanced RCC.

Purpose of the Study:

  • To review the preclinical development, scientific rationale, pharmacokinetics, and clinical efficacy/safety of cabozantinib for advanced RCC.
  • To discuss cabozantinib's role in clinical practice amidst evolving advanced RCC treatment options.
  • To provide expert opinion on cabozantinib's position in the treatment landscape.

Main Methods:

  • Review of preclinical data and scientific rationale.
  • Analysis of pharmacokinetic studies.
  • Evaluation of clinical trial data (Phase 2 and Phase 3) on efficacy and safety.

Main Results:

  • Cabozantinib improved progression-free survival (PFS), overall survival (OS), and objective response rate (ORR) versus everolimus in a Phase 3 trial.
  • It is the only therapy to show improved PFS, ORR, and OS after prior antiangiogenic therapy in a pivotal Phase 3 trial.
  • Preliminary Phase 2 data suggest efficacy in untreated poor- and intermediate-risk RCC patients.

Conclusions:

  • Cabozantinib is a significant advancement for advanced RCC, particularly after prior VEGFR-TKI therapy.
  • Clinical data suggest cabozantinib may be the most effective tyrosine kinase inhibitor (TKI) for second-line treatment.
  • Further investigation into cabozantinib's first-line use is warranted based on encouraging preliminary results.

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...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers

Receptor tyrosine kinase inhibitors (TKIs) and calcium channel blockers (CCBs) are two critical categories of drugs employed in the treatment of pulmonary artery hypertension (PAH). PAH is a disease that causes high blood pressure in the pulmonary arteries, resulting in chest pain, fatigue, and shortness of breath.
TKIs, such as imatinib (Gleevec), are particularly effective in tackling the growth and mitogenic factors that become upregulated in PAH patients. These factors contribute to the...

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists

Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme...
