FDA Approves Invokana to Treat Type 2 Diabetes

In continuation of my update on canagliflozin/Invokana...

We know that, Canagliflozin (Invokana) is a drug for the treatment of type 2 diabetes. It was developed by Mitsubishi Tanabe Pharma and is marketed under license by Janssen, a division of Johnson & Johnson. Canagliflozin is an inhibitor of subtype 2 sodium-glucose transport protein (SGLT2), which is responsible for at least 90% of the glucose reabsorption in the kidney. Blocking this transporter causes blood glucose to be eliminated through the urine. In March 2013, canagliflozin became the first SGLT2 inhibitor to be approved in the United States...

Androgen receptors found to be a potential target in breast cancer

In continuation of my update on Enzalutamide


We know that, The androgen receptor (AR), also known as NR3C4 (nuclear receptor subfamily 3, group C, member 4), is a type of nuclear receptor that is activated by binding of either of the androgenic hormones testosterone or dihydrotestosterone  in the cytoplasm and then translocating into the nucleus. The androgen receptor is most closely related to the progesterone receptor, and progestins in higher dosages can block the androgen receptor...

Estrogen and progesterone receptors, and the gene HER2 - these are the big three markers and/or targets in breast cancer. Evidence presented at the AACR Annual Meeting 2013 adds a fourth: androgen receptors.

"This is a continuing line of work with all evidence pointing toward the addition of the androgen receptor as potential target and useful marker in all of the major subtypes of breast cancer," says Jennifer Richer, PhD, investigator at the University of Colorado Cancer Center and co-director of the CU Cancer Center Tissue Processing and Procurement Core.

 The finding of androgen receptors (AR) as a potential target in breast cancer is especially important in light of its prevalence in breast cancers that don't express other hormone receptor targets or have developed resistance to treatments that target estrogen dependence. Overall, approximately 77 percent of breast cancers are positive for AR, including 88 percent of cancers that are estrogen receptor positive, 59 percent of those that are HER2 positive, and 20-32 percent of triple negative breast cancers.....

Reduced melatonin levels linked to greater diabetes risk - Life Extension Update

In continuation of my update on Melatonin....




"Melatonin receptors have been found throughout the body in many tissues including pancreatic islet cells, reflecting the widespread effects of melatonin on physiological functions such as energy metabolism and the regulation of body weight," Ciaran McMullan and colleagues at Brigham and Women's Hospital noted in their introduction to the article. "Loss-of-function mutations in the melatonin receptor are associated with insulin resistance and type 2 diabetes. Additionally, in a cross-sectional analysis of persons without diabetes, lower nocturnal melatonin secretion was associated with increased insulin resistance."

The researchers matched 370 women who developed diabetes while enrolled in the Nurses' Health Study with 370 nondiabetic participants. Morning urine samples obtained upon enrollment in 2000 were analyzed for the ratio of 6-sulfoxymelatonin (the major metabolite of melatonin) to creatinine in order to estimate overnight melatonin secretion.
Women with diabetes had a 6-sulfatoxymelatonin to creatinine ratio that was significantly lower than that of the control group. Among those whose ratio was among the lowest of the participants, the adjusted risk of developing diabetes was more than twice that of women whose ratio was among the highest group.

"This is the first time that an independent association has been established between nocturnal melatonin secretion and type 2 diabetes risk," announced Dr McMullan, who is a researcher in the Renal Division and Kidney Clinical Research Institute at BWH. "Hopefully this study will prompt future research to examine what influences a person's melatonin secretion and what is melatonin's role in altering a person's glucose metabolism and risk of diabetes."

"It is interesting to postulate from these data, in combination with prior literature, whether there is a causal role for reduced melatonin secretion in diabetes risk," the authors remark. "Further studies are needed to determine whether increasing melatonin levels (endogenously via prolonged nighttime dark exposure or exogenously via supplementation) can increase insulin sensitivity and decrease the incidence of type 2 diabetes."

FDA Approves Tecfidera - a New Treatment for Multiple Sclerosis


We know that, Dimethyl fumarate (DMF) is the methyl ester of fumaric acid. DMF was initially recognized as a very effective hypoxic cellradiosensitizer. Later, DMF combined with three other fumaric acid esters (FAE) was licensed in Germany as oral therapy for psoriasis (Fumaderm). Other diseases, such as necrobiosis lipoidica, granuloma annulare, and sarcoidosis were also found to respond to treatment with DMF in case reports or small patient series. Recently, phase III clinical trials found that DMF (BG-12) successfully reduced relapse rate and time to progression of disability in multiple sclerosis. DMF is thought to haveimmunomodulatory properties without significant immunosuppression.
In a non-medical use, DMF was applied as a biocide in furniture or shoes to prevent growths of mold during storage or transport in a humid climate. However, due to incidences of allergic reactions after skin contact the European Union banned DMF in consumer products since 1998, and since January 2009 the import of products containing DMF was also banned...

FDA Approves Kadcyla for Late-Stage Breast Cancer

We know that, Trastuzumab emtansine  in the United States, ado-trastuzumab emtansine, trade name Kadcyla) is anantibody-drug conjugate consisting of the monoclonal antibody trastuzumab (Herceptin) linked to the cytotoxic agentmertansine (DM1). Trastuzumab alone stops growth of cancer cells by binding to the HER2/neu receptor, whereas mertansine enters cells and destroys them by binding to tubulin. Because the monoclonal antibody targets HER2, and HER2 is only over-expressed in cancer cells, the conjugate delivers the toxin specifically to tumor cells.
In the EMILIA clinical trial of women with advanced HER2 positive breast cancer who were already resistant to trastuzumab alone, it improved survival by 5.8 months compared to the combination of lapatinib and capecitabine. Based on that trial, the U.S. Food and Drug Administration (FDA) approved marketing on February 22, 2013.
Trastuzumab emtansine was developed by Genentech. The planned cost is expected to be $9,800 a month, or $94,000 for a typical course of treatment..

FDA Approves Sirturo to Treat Multi-Drug Resistant Tuberculosis

In continuation of my update on bedaquiline...

Sirturo is being approved under the FDA’s accelerated approval program, which allows the agency to approve a drug to treat a serious disease based on clinical data showing that the drug has an effect on a surrogate endpoint that is reasonably likely to predict a clinical benefit to patients. This program provides patients earlier access to promising new drugs while the company conducts additional studies to confirm the drug’s clinical benefit and safe use.

The FDA also granted Sirturo fast track designation, priority review and orphan-product designation. The drug demonstrated the potential to fill an unmet medical need, has the potential to provide safe and effective treatment where no satisfactory alternative therapy exists, and is intended to treat a rare disease, respectively.
Sirturo carries a Boxed Warning alerting patients and health care professionals that the drug can affect the heart’s electrical activity (QT prolongation), which could lead to an abnormal and potentially fatal heart rhythm. The Boxed Warning also notes deaths in patients treated with Sirturo. Nine patients who received Sirturo died compared with two patients who received placebo. Five of the deaths in the Sirturo group and all of the deaths in the placebo arm seemed to be related to tuberculosis, but no consistent reason for the deaths in the remaining Sirturo-treated patients could be identified.
Sirturo’s manufacturer, Janssen Therapeutics, will distribute the drug from a single source and will provide educational materials to help ensure the drug is used appropriately.
Sirturo’s safety and effectiveness were established in 440 patients in two Phase 2 clinical trials. Patients in the first trial were randomly assigned to be treated with Sirturo plus other drugs used to treat TB, or a placebo plus other drugs used to treat TB. All patients in the second trial, which is ongoing, received Sirturo plus other TB drugs. Both studies were designed to measure the length of time it took for a patient’s sputum to be free of M. tuberculosis (sputum culture conversion, or SCC).
