Insights

Rucaparib and niraparib are new PARP inhibitors for ovarian cancer, showing efficacy in relapsed cases. They offer distinct safety and pharmacokinetic profiles compared to olaparib.

Area of Science:

  • Oncology
  • Pharmacology

Background:

  • Rucaparib and niraparib are U.S. Food and Drug Administration-approved PARP inhibitors for ovarian cancer.
  • Olaparib is also approved, and these agents have shown responses as monotherapy in previously treated ovarian cancers.

Purpose of the Study:

  • To guide advanced practitioners through the efficacy, safety, and pharmacologic profiles of rucaparib and niraparib.
  • To benchmark these agents against olaparib for ovarian cancer treatment.

Main Methods:

  • Review of clinical trial data for rucaparib, niraparib, and olaparib.
  • Comparative analysis of efficacy, safety, and pharmacokinetic data.

Main Results:

  • Niraparib shows activity in both BRCA-mutated and BRCA wild-type tumors.
  • Both rucaparib and niraparib significantly increase progression-free survival in relapsed, platinum-sensitive epithelial ovarian cancer as maintenance therapy.
  • While similar in efficacy, rucaparib and niraparib have distinct pharmacokinetic and adverse effect profiles.

Conclusions:

  • Rucaparib and niraparib are valuable additions to ovarian cancer treatment, particularly in the maintenance setting for relapsed, platinum-sensitive disease.
  • Understanding their distinct profiles is crucial for optimal patient management.

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...

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...

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 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...

Cancer-Critical Genes II: Tumor Suppressor Genes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists01:27

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists

5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...
