Insights

Bevacizumab, a vascular endothelial growth factor inhibitor, prolongs disease-free survival in metastatic colorectal cancer. This targeted therapy shows promise by hindering tumor growth and metastasis.

Area of Science:

  • Oncology
  • Molecular Biology
  • Immunology

Context:

  • Metastatic colorectal carcinoma presents significant treatment challenges.
  • Tumor angiogenesis, the development of new blood vessels, is crucial for tumor growth and metastasis.
  • Targeting angiogenesis is a key strategy in cancer therapy.

Purpose:

  • To evaluate the efficacy of bevacizumab in patients with metastatic colorectal carcinoma.
  • To assess the impact of bevacizumab on disease-free survival.
  • To explore the anti-angiogenic mechanism of bevacizumab.

Summary:

  • Bevacizumab is a humanized monoclonal antibody that targets vascular endothelial growth factor (VEGF).
  • By inhibiting VEGF, bevacizumab disrupts tumor angiogenesis, thereby limiting tumor growth and metastasis.
  • Clinical studies demonstrate a prolonged mean disease-free survival in patients treated with bevacizumab.

Impact:

  • Bevacizumab represents a significant advancement in the treatment of metastatic colorectal cancer.
  • The drug's anti-angiogenic properties offer a novel therapeutic approach.
  • Ongoing research is investigating bevacizumab for other cancer indications.

FDA Approved Drugs: Changes to Approved Drugs

Post-approval, manufacturers may modify an approved new or generic drug product. Such modifications can encompass alterations in the Active Pharmaceutical Ingredient (API), manufacturing process, formulation, batch size, manufacturing site, and container closure system (FDA Guidance for Industry, April 2004). Often, a drug product may undergo multiple changes.These modifications require careful evaluation to determine their potential impact on the drug product's identity, strength, quality,...

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 specific...

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 these...

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists

Dopamine receptor antagonists, also known as antipsychotic agents, are critical in managing chemotherapy-induced vomiting. These antiemetic agents block dopamine receptors in the chemoreceptor trigger zone (CTZ), inhibiting signal transmission to the vomiting center. Antipsychotic agents encompass phenothiazines (PTZ), butyrophenones, benzamides, and thienobenzodiazepines (Zyprexa), which are utilized for their antiemetic and sedative properties.
Phenothiazines, such as prochlorperazine...

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,...
