Olaparib Maintenance Therapy in Platinum-Sensitive Relapsed Ovarian Cancer — NEJM

We know that Olaparib, is a experimental chemotherapeutic agent, developed by KuDOS Pharmaceuticals and later by Astra Zeneca, that failed to progress through clinical trials to approval. It is an inhibitor of poly ADP ribose polymerase (PARP), an enzyme involved in DNA repair. It acts against cancers in people with hereditary BRCA1 or BRCA2 mutations, which includes many ovarian, breast and prostate

FDA Approves Intelence (Etravirine) for Pediatric Patients...

U.S. Food and Drug Administration (FDA) has approved Intelence (etravirine) to be administered in combination with other antiretroviral (ARV) medications for treatment of human immunodeficiency virus 1 (HIV-1) in treatment-experienced pediatric patients (6 years to <18 years old) who are experiencing virologic failure with HIV-1 strains resistant to a non-nucleoside reverse transcriptase inhibitor (NNRTI) and other ARVs.

This approval, which follows FDA priority review of the company’s supplemental New Drug Application, expands the Intelence indication and makes it the only NNRTI indicated for this use in both treatment-experienced children and adults with resistance to an NNRTI and other ARVs. The approval includes a new 25mg dose to allow for weight-based dosing in pediatric patients (6 years to <18 years old and weighing at least 16kg or 35.2 lbs). The 25mg tablet is expected to be available in the first half of May.

Paclitaxel drug slows damage and symptoms in (Alzheimer's disease) animal model

A compound,  epothilone D (EpoD) that previously progressed to Phase II clinical trials for cancer treatment slows neurological damage and improves brain function in an animal model of Alzheimer's disease, according to a new study.  Compound is effective in preventing further neurological damage and improving cognitive performance in a mouse model of Alzheimer's disease (AD). The results establish how the drug might be used in early-stage AD patients......

Antidepressant, TCP (Trabylcypromine) could help the workings of anticancer drug used in leukemia...

A new study shows that an antidepressant could be crucial in helping cancer treatment drugs reach their full potential.

The study by scientists at the Institute of Cancer Research found that tranylcypromine (TCP - cis and trans iosmers - below structures) – which can be used to treat psychotic depressive states - can make cancer cells vulnerable to the effects of a vitamin A- derivative drug called ATRA (above structure).

Retinoids are a class of chemical compounds related chemically to vitamin A. ATRA is already used successfully to treat a rare form of acute myeloid leukemia (AML), but up until now, has not been effective against other types of the disease. ATRA works by encouraging leukemia cells to mature and die naturally, but the researchers lead by Ar. Arthur Zelent say that the reason many AML patients do not respond to the treatment is because the genes that ATRA normally attacks are switched off by an enzyme called LSD1. The scientists discovered that using TCP to block this 'off switch' could reactivate these genes, making the cancer cells susceptible to ATRA.

The team has already joined forces with the University of Munster in Germany to start a Phase II clinical trial of the drug combination in AML patients. The authors also commented that both the retinoid ATRA and the antidepressant TCP are already available in the UK and off-patent, so these drugs should not be expensive for the health service.

New RAGE inhibitor shows promise against Alzheimer's

In continuation on drug discovery for Alzheimer's disease....
New RAGE inhibitor shows promise against Alzheimer's: Researchers have taken another crack at a promising approach to stopping Alzheimer's disease that encountered a major hurdle last year. In research published this week in the Journal of Clinical Investigation, scientists have developed a compound that targets a molecular actor known as RAGE (Receptor for Advanced Glycation End Products), which plays a central role in mucking up the brain tissue of people with the disease.
