Insights

ZD1839 (Iressa) is a targeted therapy blocking cancer cell growth. Early trials show it is well-tolerated and effective, especially for non-small cell lung cancer (NSCLC).

Area of Science:

  • Oncology
  • Pharmacology
  • Molecular Biology

Background:

  • Epidermal growth factor receptor (EGFR) signaling pathways are crucial for cancer cell proliferation and survival.
  • Targeting EGFR-tyrosine kinase offers a potential strategy for cancer treatment.

Purpose of the Study:

  • To evaluate the efficacy and tolerability of ZD1839 (Iressa), a selective EGFR-tyrosine kinase inhibitor.
  • To explore the potential of ZD1839 in various cancer types, with a focus on non-small cell lung cancer (NSCLC).

Main Methods:

  • Preclinical studies involving tumor cell lines and xenografts.
  • Phase I clinical trials in patients with advanced cancers.
  • Assessment of ZD1839's impact on tumor growth and patient tolerability.

Main Results:

  • ZD1839 demonstrated reversible tumor growth inhibition and delay in preclinical models.
  • Co-administration with cytotoxic agents enhanced ZD1839's anti-tumor activity.
  • Phase I trials indicated an acceptable safety profile and promising clinical efficacy, particularly in NSCLC patients.

Conclusions:

  • ZD1839 is a promising targeted therapy for cancer treatment.
  • Its efficacy is notable in non-small cell lung cancer (NSCLC).
  • Further clinical development, including Phase III trials for NSCLC, is warranted.

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...

Drugs for Treatment of Diarrhea-Predominant IBS

Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel Disease...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab (Humira),...
