Investigational ultra-long-acting insulin degludec reduces rates of nocturnal hypoglycaemia in type 2 diabetes patients versus insulin glargine...

Ultra-long-acting insulin degludec, (see structure) an investigational insulin being developed by Novo Nordisk, significantly reduced the rate of hypoglycaemia^* at night in adults with type 2 diabetes while obtaining equivalent improvement in glucose control compared with insulin glargine over a 52-week period. This phase 3a study was presented  at the 72^nd Scientific Sessions of the American Diabetes Association (ADA). 

The study also found that insulin degludec had significantly lower rates of severe hypoglycaemia compared to insulin glargine.

"Nocturnal, or night-time, hypoglycaemia is a particular challenge for people living with diabetes, as these episodes are often unpredictable and difficult to detect", said Bernard Zinman, lead author and director of the diabetes centre at Mount Sinai Hospital, and professor of medicine, University of Toronto: "This study demonstrated that treatment with insulin degludec significantly reduced the rate of nocturnal hypoglycaemia". 

This randomised, open-label, non-inferiority, treat-to-target trial compared efficacy and safety of insulin degludec to insulin glargine. Both insulins were given once-daily in 1,030 insulin-naïve type 2 diabetes adults inadequately controlled with oral anti-diabetic medications.

Findings of the study include:

• Nocturnal hypoglycaemic rates were significantly lower by 36% with insulin degludec than with insulin glargine (0.25 versus 0.39 episodes per patient per year; p=0.04).
• Overall confirmed hypoglycaemic rates were 1.52 versus 1.85 episodes per patient per year for insulin degludec and insulin glargine respectively (p=0.11).
• Overall severe hypoglycaemia was infrequent in both treatment populations, but it was significantly lower with insulin degludec than with insulin glargine (0.003 versus 0.023 episodes/patient-year; p=0.02).
• At one year, this noninferiority, treat-to-target trial demonstrated comparable HbA_1c reductions with insulin degludec versus insulin glargine (-1.06% versus -1.19%).^**
• Fasting plasma glucose (FPG) reductions were significantly greater with insulin degludec than with insulin glargine (-67.7 versus -59.5 mg/dl, estimated treatment difference (EDT) -7.7 mg/dl, p=0.005).

Overall adverse event rates were low and similar between groups.

Dapagliflozin more effective than sitagliptin for adult patients with type 2 diabetes

Dapagliflozin more effective than sitagliptin for adult patients with type 2 diabetes: 

In continuation of my update on dapagliflozin and sitagliptin

The study also demonstrated significant reductions in total body weight and fasting plasma glucose (FPG) levels in patients taking dapagliflozin added to sitagliptin (with or without metformin), with results maintained throughout the duration of the study extension.

Patients were actively questioned at each study visit for signs, symptoms or events suggestive of genital infections and urinary tract infections. These events were more frequent with the dapagliflozin treatment group compared to the placebo treatment group, and were generally mild to moderate in intensity, with most patients responding to standard treatment.

"Type 2 diabetes is a complex disease that often requires patients to take multiple treatments to control their blood sugar levels, with DPP4 inhibitors being some of the most widely prescribed therapies," said Serge Jabbour, M.D., Division Director of Endocrinology, Thomas Jefferson University. "In this study, dapagliflozin, in addition to diet and exercise, resulted in reduced blood sugar levels when added to sitagliptin, a DPP4 inhibitor. These findings add to our understanding of the effect of dapagliflozin in combination with commonly prescribed type 2 diabetes treatments."

Bristol-Myers Squibb Company and AstraZeneca today announced results from a Phase 3 clinical study that showed the investigational compound dapagliflozin 10 mg demonstrated significant reductions in blood sugar levels (glycosylated hemoglobin levels, or HbA1c) compared with placebo at 24 weeks when either agent was added to existing sitagliptin therapy (with or without metformin) in adult patients with type 2 diabetes.

Savient announces results from KRYSTEXXA Phase III trials on gout-related kidney disease

Post-hoc analysis evaluated more than 200 patients with CKD stages one through four (n=34, 74, 80, 23, respectively) who were randomized to receive treatment with KRYSTEXXA (pegloticase, see structure) 8 mg every other week, 8 mg every four weeks or placebo. Baseline CKD stage was similar across treatment arms, and there was no significant difference in rates of response to KRYSTEXXA by CKD stage (p<0.311). Additionally, treatment with KRYSTEXXA did not impact estimated GFR levels in patients with or without CKD. Similar results were seen in a 24-month open-label extension study.                 

In another study presented as a poster at EULAR, 35 percent of patients diagnosed with gout in Western Europe reported experiencing pain in the last 30 days (versus 20 percent in the control group of those who did not report gout; p<0.05).  Of those patients, 23 percent reported severe daily pain (versus 13.5 percent in control group; p<0.05), which impacted quality of life as assessed by the SF-12 health outcome measurement tool.  Based on study data, it is estimated that one in five gout patients in Western Europe experiences moderate to severe daily pain, one of the symptoms of gout.

Three-drug regimen provides rapid, durable responses for multiple myeloma

In continuation of my update on three drug combination

A three-drug treatment for the blood cancer multiple myeloma provided rapid, deep and potentially durable responses, researchers report today online in Blood, the Journal of the American Society of Hematology, and yesterday, Sunday, June 3, 2012, at the American Society of Clinical Oncology's Annual Meeting in Chicago, IL, USA.

The researchers, led by Andrzej J. Jakubowiak, MD, PhD, professor of medicine and director of the multiple myeloma program at the University of Chicago Medical Center, found that combining carfilzomib, a next generation proteasome inhibitor, with two standard drugs -- lenalidomide and low-dose dexamethasone compared favorably to other frontline regimens.
The longer patients stayed on the therapy, the better their response. After at least eight 28-day cycles of treatment, 61 percent of the 36 patients who remained on the therapy had a stringent complete response, defined as no detectable tumor cells or myeloma protein in the blood or bone marrow; 78 percent had at least a near complete response. More than 90 percent of patients had no progression of their disease at two years.

"These rapid and durable response rates are higher than those achieved by the best established regimens for newly diagnosed multiple myeloma," said Jakubowiak. "We have observed excellent efficacy, the best reported to date, and very good tolerability, including limited peripheral neuropathy that has been problematic with other drug combinations."

HIV drug may slow down metastatic breast cancer

The HIV drugs known as CCR5 antagonists (Maraviroc or Vicriviroc see below structures from left to right respectively) may also help prevent aggressive breast cancers from metastasizing, researchers from the Kimmel Cancer Center at Jefferson suggest in a preclinical study. 

Such drugs target the HIV receptor CCR5, which the virus uses to enter and infect host cells, and has historically only been associated with expression in inflammatory cells in the immune system. Researchers have now shown, however, that CCR5 is also expressed in breast cancer cells, and regulates the spread to other tissue.

What's more, blocking the receptor with the CCR5 antagonists Maraviroc and Vicriviroc, two drugs that slow down the spread of the HIV virus by targeting the CCR5 co-receptor of the chemokine CCL5, also prevents migration and spread of basal breast cancer cells, the researchers found.

"These results are dramatic," said Richard Pestell, M.D., Ph.D., FACP, Director of Jefferson's Kimmel Cancer Center and Chair of the Department of Cancer Biology at Thomas Jefferson University, and study senior author. "Our team showed that the CCR5/CCL5 axis plays a key role in invasiveness, and that a CCR5 antagonist can slow down the invasion of basal breast cancer cells."

"This suggests it may prove to be a viable adjuvant therapy to reduce the risk of metastasis in the basal breast cancer subtype," he added.

Basal tumors, which do not express the androgen or estrogen receptors or HER-2, are typically associated with metastasis and often do not respond to hormonal therapies. Current treatments include chemotherapy, radiation, and surgery, but all demonstrate poor outcomes, thus highlighting the urgent need for a specific targeted therapy for the subtype.

New drug found effective against rare form of basal cell skin cancer

In continuation of my up date on vismodegib..

A clinical study has demonstrated that a new drug, a targeted molecular therapy called vismodegib (trade name Erivedge™), can dramatically shrink basal cell skin cancers and prevent the formation of new ones, in patients with basal cell nevus syndrome (BCNS). This rare genetic condition causes dozens, and sometimes hundreds or thousands, of skin cancers on each patient's body. The primary treatment option is surgical removal. These study results are significant as they indicate the possibility of an alternative treatment with oral medication; although side effects remain a consideration.

Kinase Inhibitor Trials Show Melanoma Benefits | News | Drug Discovery and Development Magazine

Findings from GlaxoSmithKline (GSK) plc’s Phase 3 clinical study program evaluating single agent therapy with the targeted anti-cancer agents, dabrafenib (below left structure) and trametinib (below right structure), in patients with BRAF V600 mutation positive metastatic melanoma have been released. 

Both the BREAK3 study of dabrafenib (BRAF inhibitor) and the METRIC study of trametinib (MEK inhibitor) demonstrated a statistically significant benefit in the length of time patients with BRAF V600 mutation positive advanced or metastatic melanoma lived without progression of their disease or death (Progression Free Survival or PFS) compared to those receiving chemotherapy. Additionally, patients in the METRIC study who received trametinib lived significantly longer (overall survival or OS) than those who received chemotherapy with dacarbazine. OS data are not yet mature in the BREAK3 trial.

“The results from the clinical studies of dabrafenib and trametinib presented at this meeting represent important progress towards understanding how these investigational agents could benefit patients with advanced and metastatic melanoma. Importantly, trametinib is the first MEK inhibitor to demonstrate clinical benefit in a late phase melanoma trial.” said Dr. Rafael Amado, Head of Oncology R&D for GlaxoSmithKline. “We are planning regulatory submissions for dabrafenib and trametinib as single agent therapies and have recently started a Phase 3 program to further investigate the effect of the combination in this disease.”
