Tumor Immunotherapy01:27

Tumor Immunotherapy

2.5K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

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

854
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...

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

734
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...

FDA Approved Drugs: Changes to Approved Drugs

339
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,...

Cancer Vaccines01:30

Cancer Vaccines

1.3K
Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Area of Science:

  • Immunology
  • Oncology
  • Pharmacology

Background:

  • Pembrolizumab is a humanized monoclonal antibody targeting the programmed death receptor-1 (PD-1) protein.
  • Merck & Co. developed pembrolizumab for cancer treatment.
  • The drug functions by blocking the PD-1 pathway, a mechanism involved in immune evasion by cancer cells.

Purpose of the Study:

  • To summarize the key developmental milestones of pembrolizumab.
  • To highlight the regulatory approval process leading to its first indication.

Main Methods:

  • Review of developmental data and regulatory submissions for pembrolizumab.
  • Analysis of clinical trial outcomes for patients with advanced melanoma.

Main Results:

  • Pembrolizumab received its first global regulatory approval in the US.
  • Approval is for advanced, unresectable, or metastatic malignant melanoma.
  • Specific patient populations include those with disease progression after ipilimumab and/or BRAF inhibitor therapy.

Conclusions:

  • Pembrolizumab represents the first anti-PD-1 therapy approved in the US.
  • This approval signifies a major advancement in the treatment landscape for advanced melanoma.
  • The drug is currently under regulatory review in the European Union.
