Abstract

Insights

Neratinib plus capecitabine offers a valid treatment option for advanced HER2-positive breast cancer patients who have progressed on prior therapies. This combination demonstrated improved progression-free survival and delayed central nervous system disease progression.

Area of Science:

  • Oncology
  • Pharmacology
  • Clinical Trials

Background:

  • Advanced HER2-positive breast cancer has several emerging treatment options.
  • Neratinib is an irreversible pan-HER tyrosine kinase inhibitor (TKI).
  • The NALA trial compared neratinib plus capecitabine to lapatinib plus capecitabine.

Purpose of the Study:

  • To review preclinical and clinical data of neratinib plus capecitabine.
  • To summarize efficacy and safety from Phase I/II and III trials.
  • To position this regimen within the treatment landscape for HER2-positive metastatic breast cancer.

Main Methods:

  • Analysis of preclinical and clinical data.
  • Summarization of efficacy and safety results from multiple trials.
  • Discussion of the regimen in the context of treatment progression.

Main Results:

  • Neratinib plus capecitabine showed increased progression-free survival (PFS).
  • The combination improved time to intervention for central nervous system disease.
  • Diarrhea was the primary adverse event associated with neratinib.

Conclusions:

  • Neratinib plus capecitabine is a viable option for advanced HER2-positive breast cancer after two prior anti-HER2 regimens.
  • Further research into predictive biomarkers for neratinib efficacy is warranted.
  • Managing side effects like diarrhea with prophylactic treatment is crucial.

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...

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy.  SP binds and activates...

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...

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...
