FDA Approved Drugs: Changes to Approved Drugs

136
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,...

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers01:26

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers

366
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...

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists

337
Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

8.5K
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 Medicine

5.8K
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...

Area of Science:

  • Oncology
  • Pharmacology
  • Genetics

Background:

  • Neurofibromatosis type 1 (NF1) is a genetic disorder causing tumor growth.
  • Plexiform neurofibromas associated with NF1 can be symptomatic and inoperable.
  • Targeted therapies are needed for NF1-associated tumors.

Purpose of the Study:

  • To summarize the development of selumetinib for NF1.
  • To highlight the approval of selumetinib for pediatric patients with NF1.
  • To review the efficacy and safety data leading to the approval.

Main Methods:

  • Review of clinical trial data, specifically the SPRINT trial.
  • Analysis of selumetinib's mechanism of action as a MEK1/2 inhibitor.
  • Summary of regulatory milestones and approvals.

Main Results:

  • Selumetinib demonstrated efficacy in treating pediatric patients with NF1.
  • The drug was approved in the USA for symptomatic, inoperable plexiform neurofibromas in patients aged ≥2 years.
  • Orphan drug status was granted for thyroid cancer and NF1 treatments.

Conclusions:

  • Selumetinib represents a significant advancement in NF1 treatment.
  • The approval provides a crucial therapeutic option for children with NF1-related plexiform neurofibromas.
  • Further research may explore selumetinib's potential in other NF1-related conditions and cancers.
