Idelalisib (Zydelig(®)) is a highly specific small-molecule phosphatidylinositol-3-kinase (PI3Kδ) inhibitor that has been developed as an oral treatment for B cell haematological cancers.It has received its first approval in the US in July 2014 for the treatment of relapsed chronic lymphocytic leukaemia(CLL), relapsed follicular B-cell non-Hodgkin lymphoma(NHL) and relapsed small lymphocytic lymphoma (SLL) [corrected]. Idelalisib is under regulatory review in the EU-where it has received a positive opinion from the European Medicines Agency Committee for Medicinal Products for Human Use-and in clinical development for CLL in Australia and Canada. This article summarizes the milestones in the development of Idelalisib leading to this first approval for relapsed CLL, NHL and SLL.

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,...

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...

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...
