FDA Approves Brenzavvy (bexagliflozin) for the Treatment of Adults with Type 2 Diabetes

TheracosBio  announced  the U.S. Food and Drug Administration (FDA)   approval of  Brenzavvy (bexagliflozin), an oral sodium-glucose cotransporter 2 (SGLT2) inhibitor. Brenzavvy is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes. Brenzavvy is not recommended for patients with type 1 diabetes mellitus or for the treatment of diabetic ketoacidosis. Brenzavvy is contraindicated in patients who are hypersensitive to bexagliflozin or any tablet ingredient and is not indicated for the treatment of type 2 diabetes in patients with end stage renal disease or who are receiving dialysis.

The FDA approval is based on results from a clinical program that evaluated the safety and efficacy of Brenzavvy in 23 clinical trials enrolling more than 5,000 adults with type 2 diabetes mellitus. Phase 3 studies showed Brenzavvy significantly reduced hemoglobin A1c and fasting blood sugar after 24 weeks, either as a monotherapy, in combination with metformin, or as an add-on to standard-of-care treatment consisting of a variety of regimens, including metformin, sulfonylureas, insulin, DPP4 inhibitors, or combinations of these agents. Although Brenzavvy is not approved for weight or blood pressure reduction, modest decreases in both weight and systolic blood pressure have been observed in the clinical program.



“As a class of drugs, SGLT2 inhibitors have shown tremendous benefit in treating adults with type 2 diabetes,” said Dr. Mason Freeman, M.D., Director of the Translational Research Center at Massachusetts General Hospital. “Being involved in all of the clinical trials for Brenzavvy, I am greatly impressed with the efficacy of the drug in reducing blood glucose levels and I believe it is an important addition to the SGLT2 inhibitor class of drugs.”

Brenzavvy treatment can be initiated in adults with type 2 diabetes with an estimated glomerular filtration rate (eGFR) greater than 30 mL/min/1.73 m2. Patients with eGFR less than 60 and greater than 30 mL/min/1.73 m2 are said to be in stage 3 chronic kidney disease, and for these patients metformin is often avoided due to the risk of lactic acidosis.

“Today's FDA approval represents a significant milestone for TheracosBio and provides an important treatment option to patients who suffer from type 2 diabetes. We look forward to bringing Brenzavvy to market,” said Albert R. Collinson, Ph.D., President and CEO of TheracosBio. “The approval of the Brenzavvy NDA is a result of the tireless work of the TheracosBio team and investigators. I want to thank all of the patients who took part in our clinical trials.”

According to the U.S. Centers for Disease Control and Prevention, more than 33 million Americans have type 2 diabetes, which means their bodies don’t use insulin correctly and as a result their blood sugar levels are too high. While some people can control their blood sugar levels with exercise and a healthy diet, others may need additional help to achieve good blood sugar (glycemic) control.

SGLT2 inhibitors are a class of prescription medicines that lower blood sugar by causing the kidneys to remove sugar from the body through urine.

Brenzavvy is available as 20 mg oral tablets recommended to be taken once daily, in the morning with or without food.

FDA Approves Mounjaro (tirzepatide) Injection for the Treatment of Adults with Type 2 Diabetes




The U.S. Food and Drug Administration (FDA) has approved Mounjaro (tirzepatide) injection, Eli Lilly and Company's (NYSE: LLY) new once-weekly GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 (glucagon-like peptide-1) receptor agonist indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes. Mounjaro has not been studied in patients with a history of pancreatitis and is not indicated for use in patients with type 1 diabetes mellitus.

As the first and only FDA-approved GIP and GLP-1 receptor agonist, Mounjaro is a single molecule that activates the body's receptors for GIP and GLP-1, which are natural incretin hormones.1

"Mounjaro delivered superior and consistent A1C reductions against all of the comparators throughout the SURPASS program, which was designed to assess Mounjaro's efficacy and safety in a broad range of adults with type 2 diabetes who could be treated in clinical practice. The approval of Mounjaro is an exciting step forward for people living with type 2 diabetes given the results seen in these clinical trials," said Juan Pablo Frías, M.D., Medical Director, National Research Institute and Investigator in the SURPASS program.

Mounjaro will be available in six doses (2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, 15 mg) and will come in Lilly's well-established auto-injector pen with a pre-attached, hidden needle that patients do not need to handle or see.

The approval was based on results from the phase 3 SURPASS program, which included active comparators of injectable semaglutide 1 mg, insulin glargine and insulin degludec. Efficacy was evaluated for Mounjaro 5 mg, 10 mg and 15 mg used alone or in combination with commonly prescribed diabetes medications, including metformin, SGLT2 inhibitors, sulfonylureas and insulin glargine. Participants in the SURPASS program achieved average A1C reductions between 1.8% and 2.1% for Mounjaro 5 mg and between 1.7% and 2.4% for both Mounjaro 10 mg and Mounjaro 15 mg. While not indicated for weight loss, mean change in body weight was a key secondary endpoint in all SURPASS studies. Participants treated with Mounjaro lost between 12 lb. (5 mg) and 25 lb. (15 mg) on average.1

Side effects reported in at least 5% of patients treated with Mounjaro include nausea, diarrhea, decreased appetite, vomiting, constipation, indigestion (dyspepsia), and stomach (abdominal) pain. The labeling for Mounjaro contains a Boxed Warning regarding thyroid C-cell tumors. Mounjaro is contraindicated in patients with a personal or family history of medullary thyroid carcinoma or in patients with Multiple Endocrine Neoplasia syndrome type 2.1

"Lilly has a nearly 100-year heritage of advancing care for people living with diabetes – never settling for current outcomes. We're not satisfied knowing that half of the more than 30 million Americans living with type 2 diabetes are not reaching their target blood glucose levels," said Mike Mason, president, Lilly Diabetes. "We are thrilled to introduce Mounjaro, which represents the first new class of type 2 diabetes medication introduced in almost a decade and embodies our mission to bring innovative new therapies to the diabetes community."

Acid reflux drug may be a promising therapy to reduce preterm birth

In continuation of my update on Lansoprazole
Lansoprazole, an over-the-counter acid reflux drug that is often taken by pregnant women, may be a promising therapy to reduce preterm birth, according to a computational drug repurposing study that also tested several of the drugs in mice.
Lansoprazole.svg
The study also identified 12 other FDA-approved drugs that are deemed safe in pregnancy. While the drugs encompass a variety of modalities, the scientists said they all appear to act on biological pathways that affect the immune response, which is implicated in preterm birth.
"Inflammation clearly plays a role in initiating labor and preterm birth," said Marina Sirota, PhD, assistant professor of pediatrics, a member of the Bakar Computational Health Sciences Institute at UCSF, and the senior author of the study, published Feb. 13, 2020, in JCI Insight. "Immune pathways are very significantly dysregulated in women who end up delivering preterm, and they're also dysregulated in babies who are born early. However, we have seen from our previous work that there is an interaction between the maternal and fetal immune systems and a breakdown in maternal-fetal tolerance."
To identify candidate drugs that might be effective in preventing preterm birth, the scientists first looked at which genes were up- or down-regulated in the blood cells of women who experienced spontaneous preterm birth to identify a gene expression "signature." Then they looked for the opposite signature in cells that had been exposed to 1,309 different drugs, reasoning that if a drug could correct the effects that preterm birth had on the women's blood cells, the drugs might also prevent preterm birth itself.
The scientists identified 83 drug candidates, but when they excluded those found to have pregnancy risks in animal or human studies, they wound up with 13 drugs, ranked according to their "reversal score," a measure of the extent to which they were able to reverse the gene expression signature of preterm birth.
The other drugs identified by the computational screen included progesterone, which is already used to treat recurrent spontaneous preterm birth, folic acid, which is given to women during pregnancy to prevent birth defects, three antibiotics, an antifungal, an antidepressant, an anti-diabetic, and a blood pressure medication.
The fact that predictable drugs like progesterone came up in the screen gave the scientists confidence that the drugs they identified may turn out to be effective once they are tested in pregnant women. Three of the other drugs that came up in the screen--folic acid, clotrimazole and metformin--have also been shown in previous studies to be effective against preterm birth.
Finding progesterone on the list was a promising validating step. Four of the drugs on our list have seen effectiveness in past studies that were either experimental or retrospective. This leads us to believe in the biology behind the identification of these drugs."
Brian Le, PhD, postdoctoral scholar in the UCSF Department of Pediatrics and the Bakar Computational Health Sciences Institute, and the first author of the study
The scientists chose lansoprazole for further testing because, in addition to its high reversal score, it is available over the counter, and they know from their previous work that it affects a stress-response protein, heme oxygenase-1, that has been linked with pregnancy disorders. Lansoprazole, which is a proton-pump inhibitor marketed as Prevacid, had the second-highest reversal score of the 13 drugs identified as being safe and effective. Progesterone was further down the list.
The scientists tested lansoprazole in pregnant mice that had been given a bacterial component to induce inflammation, which causes some fetuses to die in utero, where they are reabsorbed. When these mice were given lansoprazole, they had more viable fetuses. Lansoprazole also worked better in these mice than progesterone.
Although it is a good measure of how inflammation affects pregnancy in mice, the scientists said the fetal resorption mouse model is not an adequate model of human preterm birth. They said more work, including studies in people, would need to be done before lansoprazole or any of the dozen other drugs they identified could be proven effective in pregnant women at risk for preterm birth. But the computational study provides leads for a condition that currently has few treatment options.
"This, basically, is a proof of concept that this drug has anti-inflammatory properties, which are not the properties the drug was designed for," said David K. Stevenson, MD, a professor of pediatrics at Stanford University and an author of the study. "This is a short way to get to new therapeutics for known diseases."

Statin use alone or with metformin may increase survival in high-risk prostate cancer patients

In continuation of my update on metformin



Image result for metformin




Among high-risk prostate cancer patients - those with high PSA and Gleason scores of 8 or more - many will develop a difficult-to-treat disease. Preliminary research suggests that two commonly prescribed medications, cholesterol-lowering statins and the diabetes therapy metformin may have anticancer effects. However, it is unclear which of these two medications - commonly prescribed together -- contributes the most and whether they can impact high-risk prostate cancer. New research shows that statins, alone or with metformin, increase survival in men with high-risk prostate cancer.
"Both metformin and statins have been associated with longer life in prostate cancer patients, yet because they are commonly prescribed together, no study we know of has looked at these two medications separately," says senior author Grace Lu-Yao, PhD, associate director of Population Science at the Sidney Kimmel Cancer Center--Jefferson Health, one of only eight NCI-designated cancer centers nationwide with a prostate cancer program of excellence.
The study, published in Cancer Medicine on Feb 8th, looked at a number of statin therapies, and metformin, an anti-diabetic medication, in high-risk prostate cancer populations.
Using data from the Surveillance, Epidemiology and End Results (SEER-18) database linked with Medicare files, Dr. Lu-Yao and colleagues looked at patients diagnosed with cancer from 2007 through to 2011. Based on 12,700 patients, the researchers observed that statins alone or in combination with metformin was significantly associated with reduced mortality from all causes.
Dr. Lu-Yao and colleagues saw the highest median survival of 3.9 months in men who took both metformin and statins, 3.6 with statins alone and 3.1 years with metformin alone. The median survival for those who did not use either drug was also 3.1 years.
With respect to prostate mortality, metformin plus statin was associated with a 36% reduction in risk of death followed by statins alone. Those taking metformin alone were relatively rare, and there was no significant association with all-cause mortality."

Interestingly, the study revealed that men who took atorvastatin, pravastatin, or rosuvastatin - but not lovastatin - demonstrated a reduction in mortality compared with non-users, which is consistent with the findings from a recent population-based cohort study using Taiwan National Health Insurance Research Data. The Taiwanese research showed that these three statins are more effective at lowering triglycerides and low-density lipoprotein cholesterol and raising high-density lipoprotein cholesterol than other statins in patients with hypercholesterolemia.
Of the three statins studied, men on atorvastatin did have a longer median time to progression on androgen deprivation therapy compared to those who weren't treated with statins. "Although the exact mechanisms remain unknown, it is worth noting that atorvastatin exhibits a potent lipid-lowering effect per dose of any statin, and has the greatest bioavailability and one of the longest half-lives," says to Dr. Lu-Yao.
The data presented in the current study provide crucial insight for the design of future randomized clinical trials of statin for high-risk patients with prostate cancer. Based on the existing evidence, a well-designed clinical trial is warranted to investigate the roles of statins and combination statins/metformin to reduce the mortality cancer of the prostate.
"Our study showed that the effects were more pronounced in patients taking statins after the diagnosis of prostate cancer, 54% reduction in PCA mortality among patients with high-risk prostate cancer," says Lu-Yao. "This magnitude of reduction is comparable to the results of men treated with androgen signaling inhibitors." Statins are relatively inexpensive with good safety records. Further studies to understand the mechanisms of the observed association and its potential clinical utility are warranted.

Metformin could help leaky gut


Metformin.svg

In continuation of  my update on metformin

A team of researchers from University of California, San Diego, have successfully used gut organoids in their lab to show the effects of medications to treat conditions such as “leaky gut”. The study was titled, “The stress polarity signaling (SPS) pathway serves as a marker and a target in the leaky gut barrier: implications in aging and cancer,” and was published in the journal Life Science Alliance today..

The team found that they could use 3 dimensional gut cells in a Petri dish in the form of a gut organoids and test the drugs for their efficacy on leaky guts. These organoids can successfully recreate the molecular system within the lab including intestinal lining cells etc. These cells are normally sealed to prevent leakage. In certain disease conditions, the seals may be dysfunctional leading to leaky guts, wrote the researchers. These conditions are commonly seen in cancers and among the elderly, they explained. In this condition there may be leakage of microbes as well as vital molecules from the intestines into the abdominal cavities.
To create these organoids the team used donated intestinal cells from the patients. The intestines typically have crests and crypts with peaks and valleys. From the crypts they could isolate stem cells. These cells were used to create the three dimensional organoids within the labs, the team wrote. The stem cells grew to become four types of cells that normally are noted within the gut. These cells then rolled up to become mini guts within the Petri dishes they wrote. Now the organoids were capable of being tested.
University of California San Diego School of Medicine researchers thus used 3D models of human intestines in the petri dishes. These cells were donated by real patients suffering from leaky gut. The cells were created into 3D mini organoids so that they could mimic the real intestines. The team then found certain biomarkers that were characteristic of intestines that had the leakage problem. The team speculates that these markers could help researchers diagnose this condition early and also track the progression of the disease over a course of time.
For their study they used a commonly used diabetes medicine Metformin to try and plug the leaks within the intestinal walls. The study led by Pradipta Ghosh, MD, professor of cellular and molecular medicine at UC San Diego School of Medicine and Moores Cancer Center, and senior author Soumita Das, PhD, associate professor of pathology at UC San Diego School of Medicine, revealed that this commonly used drug could help patients with a leaky gut.
Ghosh and Das had earlier, in another study showed that a mechanism called the stress-polarity signaling pathway could help close the gaps between the cells and prevent the leakage. In that study they had also noted that the connections and bonds between the cells came apart due to the stress.
This new study revealed that Metformin may work to activate certain chemical reactions that could tighten these junctions and thus prevent the leakage. The team says that their success has been seen only in the Petri dishes on the mini organoids of the gut yet. They need to replicate it in humans to see if the drug could actually help patients with leaky gut conditions. They added however that the success of the drug in these organoids is a big step in proving that the drug could actually help. Metformin, they wrote raise the levels of a protein called occluding that can tighten the junctions between cells. If successful, this could help a large number of patients, they explained.
Ghosh said, “Lots of research is done in mice that are inbred so that they are genetically identical, all in the same cage, eating the same diet, in order to remove these variables from the studies. But lab mice are far more standardized than the same human from day to day, or patients we see in the clinics. Here, our model is a better representation of humanity. On the other hand, it also means that each organoid is its own unique experiment. We have to test many organoids to be able to make any claim, which we did in our study.” Das added, “I think you'd be hard pressed to find a disease in which systemic inflammation is not a driver. That's why, even though there are so many things we still don't know, we're excited about the broad potential this model and these findings open for developing personalized leaky gut therapeutics that target AMPK and the stress-polarity signaling pathway.”
There may be several disease conditions that lead to weakening of the bonds between the cells and the junctional cells between two intestinal cells, wrote the researchers. This leads to leakage of the molecules from within the intestines as well as leakage of microbes. This can trigger the immune system leading to a state of chronic inflammation. Inflammatory bowel diseases such as ulcerative colitis and Crohn’s disease as well as other conditions such as liver damage, cancers, diabetes, atherosclerosis, arthritis and even dementia could be associated with leaky gut cells say researchers. Till date there have been no way this problem could be studied, let alone solved, wrote the researchers. This new study finally paves a way where the condition could be replicated in the lab and studied at its molecular level.
For this study the team took the mini organoids and opened up the rolled balls to expose the intestinal surface. Over these they used bacteria and other stressors to weaken the junctional cells and create leaky openings. Now they could study the molecular mechanisms as well as the drugs which could help tightening these bonds between the cells to prevent leakage.

FDA Approves Trijardy XR (empagliflozin/linagliptin/metformin) for Type 2 Diabetes in Adults

In continuation of my update on empagliflozin/linagliptin/metformin 


Empagliflozin.svg    Metformin.svg


The U.S. Food and Drug Administration (FDA) has approved Trijardy XR (empagliflozin/linagliptin/metformin hydrochloride extended release tablets) to lower blood sugar in adults with type 2 diabetes, along with diet and exercise. Trijardy XR provides three type 2 diabetes medicines in one pill, including Jardiance® (empagliflozin), Tradjenta® (linagliptin) and metformin hydrochloride extended release. Trijardy XR is marketed by Boehringer Ingelheim Pharmaceuticals, Inc. and Eli Lilly and Company (NYSE: LLY).

"Many adults living with type 2 diabetes who are already on a treatment plan including multiple medications still struggle to keep their blood sugar under control, and may require additional agents to reach their A1C targets," said Ralph DeFronzo, M.D., professor and diabetes division chief, UT Health San Antonio. "Adding new medicines to an individual's plan can be challenging for some, which is why new treatment options that can help improve blood sugar without the burden of an increased pill count are important. In addition, type 2 diabetes is a complex disease that often requires the use of multiple antidiabetic medications to improve glycemic control. Having three different diabetes medications in a single tablet is an important advance in diabetes treatment."
In the U.S., both Jardiance and Tradjenta are once-daily tablets used along with diet and exercise to lower blood sugar in adults with type 2 diabetes. Jardiance is also approved to reduce the risk of cardiovascular death in adults with type 2 diabetes who have known cardiovascular disease. Jardiance is not for people with type 1 diabetes or for people with diabetic ketoacidosis (increased ketones in the blood or urine). Tradjenta is not for people with type 1 diabetes or for the treatment of diabetic ketoacidosis. Tradjenta has not been studied in people with a history of pancreatitis and it is unknown if using Tradjenta increases the risk of developing pancreatitis in these people. 
"We are proud to offer Trijardy XR as a new once-daily option combining three well-established medicines, including an extended-release version of metformin, the most commonly prescribed initial treatment for type 2 diabetes, Jardiance, the most prescribed SGLT2 inhibitor, and Tradjenta, the only single-dose DPP-4 inhibitor," said Mohamed Eid, M.D., M.P.H., M.H.A., vice president, Clinical Development & Medical Affairs, Cardio-Metabolism & Respiratory Medicine, Boehringer Ingelheim Pharmaceuticals, Inc. "We believe Trijardy XR has the potential to help adults with type 2 diabetes conveniently manage their treatment, especially those who are taking other medications and working on the necessary lifestyle changes."
Trijardy XR is not recommended for people with type 1 diabetes or diabetic ketoacidosis (increased ketones in the blood or urine). Trijardy XR has not been studied in patients with a history of pancreatitis. It is unknown whether patients with a history of pancreatitis are at an increased risk for the development of pancreatitis while using Trijardy XR. The labeling for Trijardy XR contains a warning for lactic acidosis, a rare but serious complication that can occur due to metformin accumulation, and is common to all products containing metformin.
The FDA approval of Trijardy XR is based on two randomized open-label trials that assessed the bioequivalence of empagliflozin, linagliptin and metformin hydrochloride extended release fixed-dose combination tablets and their individual components in healthy adults. The safety profile of Trijardy XR was found to be consistent with its individual components.
"The approval of Trijardy XR reflects our commitment to the diabetes community and to innovation that addresses evolving needs," said Jeff Emmick, M.D. Ph.D., vice president, Product Development, Lilly. "We developed Trijardy XR because many people with type 2 diabetes need help managing this complex condition without adding more pills to their treatment plan. We look forward to making this new option available soon."
Trijardy XR is not for people who have severe kidney problems, end stage renal disease, or are on dialysis, have a serious condition called metabolic acidosis or diabetic ketoacidosis (increased ketones in the blood or urine), or are allergic to Jardiance, Tradjenta, metformin, or any of the ingredients in Trijardy XR. There have been postmarketing reports of acute pancreatitis, including fatal pancreatitis, in patients taking linagliptin, a component of Trijardy XR. Take careful notice of potential signs and symptoms of pancreatitis. If pancreatitis is suspected, promptly discontinue Trijardy XR and initiate appropriate management. It is unknown whether patients with a history of pancreatitis are at increased risk for the development of pancreatitis while using Trijardy XR.
Trijardy XR will be available in four different dosages, including: 5 mg empagliflozin/2.5 mg linagliptin/1000 mg metformin HCl extended-release; 10 mg empagliflozin/5 mg linagliptin/1000 mg metformin HCl extended-release; 12.5 mg empagliflozin/2.5 mg linagliptin/1000 mg metformin HCl extended-release; and 25 mg empagliflozin/5 mg linagliptin/1000 mg metformin HCl extended-release.
What is Trijardy XR?
Trijardy XR is a prescription medicine that contains 3 diabetes medicines, empagliflozin (JARDIANCE), linagliptin (TRADJENTA), and metformin hydrochloride. Trijardy XR can be used along with diet and exercise to lower blood sugar in adults with type 2 diabetes, and in adults with type 2 diabetes who have known cardiovascular disease when empagliflozin (JARDIANCE), one of the medicines in Trijardy XR, is needed to reduce the risk of cardiovascular death.
Trijardy XR is not for people with type 1 diabetes, or for people with diabetic ketoacidosis (increased ketones in the blood or urine).
If you have had pancreatitis (inflammation of the pancreas) in the past, it is not known if you have a higher chance of getting pancreatitis while you take Trijardy XR.

FDA Approves Victoza (liraglutide) for the Treatment of Pediatric Patients 10 Years or Older with Type 2 Diabetes


In continuation of my update on Victoza (liraglutide)
The U.S. Food and Drug Administration   approved Victoza (liraglutide) injection for treatment of pediatric patients 10 years or older with type 2 diabetes. Victoza is the first non-insulin drug approved to treat type 2 diabetes in pediatric patients since metformin was approved for pediatric use in 2000. Victoza has been approved to treat adult patients with type 2 diabetes since 2010.
“The FDA encourages drugs to be made available to the widest number of patients possible when there is evidence of safety and efficacy,” said Lisa Yanoff, M.D, acting director of the Division of Metabolism and Endocrinology Products in the FDA’s Center for Drug Evaluation and Research. “Victoza has now been shown to improve blood sugar control in pediatric patients with type 2 diabetes. The expanded indication provides an additional treatment option at a time when an increasing number of children are being diagnosed with this disease.”
Type 2 diabetes is the most common form of diabetes, occurring when the pancreas cannot make enough insulin to keep blood sugar at normal levels. Although type 2 diabetes primarily occurs in patients over the age of 45, the prevalence rate among younger patients has been rising dramatically over the past couple of decades. The Diabetes Report Card published by the U.S. Centers for Disease Control and Prevention estimates that more than 5,000 new cases of type 2 diabetes are diagnosed each year among U.S. youth younger than age 20.
Victoza improves blood sugar levels by creating the same effects in the body as the glucagon-like peptide (GLP-1) receptor protein in the pancreas. GLP-1 is often found in insufficient levels in type 2 diabetes patients. Like GLP-1, Victoza slows digestion, prevents the liver from making too much glucose (a simple sugar), and helps the pancreas produce more insulin when needed. As noted on the label, Victoza is not a substitute for insulin and is not indicated for patients with type 1 diabetes or those with diabetic ketoacidosis, a condition associated with diabetes where the body breaks down fat too quickly because there is inadequate insulin or none at all. Victoza is also indicated to reduce the risk of major adverse cardiovascular events in adults with type 2 diabetes and established cardiovascular disease; however, its effect on major adverse cardiovascular events in pediatrics was not studied and it is not indicated for this use in children.
The efficacy and safety of Victoza for reducing blood sugar in patients with type 2 diabetes was studied in several placebo-controlled trials in adults and one placebo-controlled trial with 134 pediatric patients 10 years and older for more than 26 weeks. Approximately 64% of patients in the pediatric study had a reduction in their hemoglobin A1c (HbA1c) below 7% while on Victoza, compared to only 37% who achieved these results with the placebo. HbA1c is a blood test that is routinely performed to evaluate how well a patient’s diabetes is controlled, and a lower number indicates better control of the disease. These results occurred regardless of whether the patient also took insulin at the same time. Adult patients who took Victoza with insulin or other drugs that increase the amount of insulin the body makes (e.g., sulfonylurea) may have an increased risk of hypoglycemia (low blood sugar). Meanwhile, pediatric patients 10 years and older taking Victoza had a higher risk of hypoglycemia regardless of whether they took other therapies for diabetes.
The prescribing information for Victoza includes a Boxed Warning to advise health care professionals and patients about the increased risk of thyroid C-cell tumors. For this reason, patients who have had, or have family members who have ever had medullary thyroid carcinoma (MTC) should not use Victoza, nor should patients who have an endocrine system condition called multiple endocrine neoplasia syndrome type 2 (MEN 2). In addition, people who have a prior serious hypersensitivity reaction to Victoza or any of the product components should not use Victoza. Victoza also carries warnings about pancreatitis, Victoza pen sharing, hypoglycemia when used in conjunction with certain other drugs known to cause hypoglycemia including insulin and sulfonylurea, renal impairment or kidney failure, hypersensitivity and acute gallbladder disease. The most common side effects are nausea, diarrhea, vomiting, decreased appetite, indigestion and constipation.

FDA Approves Qternmet XR (dapagliflozin, saxagliptin and metformin hydrochloride) for Type 2 Diabetes




In continuation of my update on dapagliflozin, and metformin hydrochloride



Dapagliflozin skeletal.svg 
Dapagliflozin           Saxagliptin structure.svg Saxagliptin                                   and  Thumb(Metformin)

The US Food and Drug Administration (FDA) has approved Qternmet XR(dapagliflozin, saxagliptin and metformin hydrochloride) extended release tablets as an oral adjunct treatment to diet and exercise to improve glycaemic control in adults with type-2 diabetes (T2D).
The approval is based on two Phase III trials, which evaluated combinations of dapagliflozin and saxagliptin on a background of metformin over 24 weeks, in patients with inadequately-controlled T2D.
In one trial, treatment with 5mg dapagliflozin/5mg saxagliptin in addition to metformin demonstrated statistically-significant decreases in HbA1c (average blood glucose levels), and an increase in the number of patients achieving the recommended HbA1c treatment goal of <7%. In the second trial, treatment with 10mg dapagliflozin/5mg saxagliptin in addition to metformin extended release demonstrated statistically-significant decreases in HbA1c, and an increase in the number of patients achieving an HbA1c <7%.
The safety results of the individual medicines in these trials were consistent with their known profile.

About Qternmet XR

Qternmet XR is a once-daily, oral medicine compromised of the selective sodium‑glucose cotransporter-2 (SGLT-2) inhibitor dapagliflozin, the dipeptidyl peptidase‑4 (DPP‑4) inhibitor saxagliptin and metformin hydrochloride extended release. Qternmet XR is approved in the US as an adjunct to diet and exercise to improve glycaemic control in adults with type-2 diabetes.

Could Diabetes Drug Metformin Help Keep People Slim?

New research suggests a first-line drug for treating type 2 diabetes   'metformin'  may help people with pre-diabetes maintain long-term weight loss.

Metformin.svg
People who lost weight while taking metformin maintained a loss of about 6% of their body weight for six to 15 years. People who lost weight through lifestyle changes -- eating healthily and exercising regularly -- managed to keep off just under 4% of their initial body weight for the same period, the study found.
Metformin doesn't seem to be particularly helpful for shedding pounds in the first place, though. In fact, an earlier phase of the study found that people were much more likely to lose 5% or more of their body weight through lifestyle changes -- healthy eating and exercising -- than by using metformin.
"Although lifestyle changes were superior for inducing weight loss early on, metformin was better for long-term weight maintenance," said senior study author Dr. Kishore Gadde. He's a professor in heart disease prevention at the Pennington Biomedical Research Center in Baton Rouge, La.
Not everyone is convinced that metformin can keep you slim, however. After reviewing the findings, Dr. Joel Zonszein, director of the Clinical Diabetes Center at Montefiore Medical Center in New York City, said, "This study was very well done, but it doesn't show metformin is effective for everyone. The ones on metformin who did lose weight only regained a little less weight."
He added that metformin isn't well-tolerated by a lot of people. It can cause digestive problems, such as nausea and diarrhoea.
An  effective intervention for losing weight and maintaining that loss is clearly needed. Nearly three-quarters of the American population is overweight or obese -- a major risk factor for type 2 diabetes, according to the U.S. Centers for Disease Control and Prevention.
Losing a significant amount of weight more than 5% of your body weight  seems to help prevent pre-diabetes from turning into type 2 diabetes, and can help delay the progression of type 2 diabetes.
The latest study was a continuation of the three-year diabetes prevention clinical trial that compared three different groups of people with pre-diabetes to see what type of intervention would help prevent type 2 diabetes from developing. One group was given metformin, another was coached on intensive lifestyle changes, and the third group was given a placebo.
This study found that lifestyle changes led to the greatest initial weight loss, followed by the metformin group, according to Gadde.
From the original study group -- more than 3,000 people -- just over 1,000 lost more than 5% of their body weight.
The researchers followed this group for as long as 15 years to see who maintained their weight loss.
People taking metformin had the greatest weight loss from years six to 15, according to the study. The study also found that being older and losing a greater amount of weight in the first year were consistent predictors of lasting weight loss, the study authors said.
Gadde said it's not exactly clear why the metformin group was better at maintaining weight loss. "Metformin does reduce food intake a little bit, but it's not a dramatic effect. And, from what we know, it doesn't significantly alter energy expenditure."
He said other recent research suggests that metformin may alter the body's microbiome (the healthy bacteria in your gut). It also seems that metformin may have some effects on muscle function. But Gadde said, more research is necessary to know for sure.

Diabetes drug use during pregnancy may increase risk of obesity or overweight in children

In continuation of my update on metformin

When women take the common diabetes medication metformin during pregnancy, it may put their children at increased risk of having obesity or overweight.
A growing number of pregnant women are taking metformin to treat gestational diabetes or a condition called polycystic ovary syndrome (PCOS). PCOS is a common cause of infertility and can put women at risk of developing diabetes and other metabolic health problems. PCOS affects an estimated 7 percent to 10 percent of women of childbearing age, according to the Hormone Health Network.
When pregnant women with PCOS or gestational diabetes take metformin, the medication crosses the placenta and is passed to the fetus.
"Our findings indicate the offspring of women who took metformin for PCOS during pregnancy are more likely to meet the criteria for obesity or overweight than children whose mothers were given a placebo during pregnancy," said the study's first author, Liv Guro Engen Hanem, M.D., of the Norwegian University of Science and Technology in Trondheim, Norway. "The results were surprising, since limited past research in this area had suggested metformin would have a protective effect on the children's metabolic health."

The researchers invited parents of 292 children who participated in two previous randomized clinical trials to be part of this study. In the previous trials, pregnant women with PCOS were assigned to take either metformin or a placebo during pregnancy. The researchers wound up reviewing body mass index (BMI) and other measurements for 161 children born following the two earlier studies.
At four years of age, the children whose mothers were randomized to metformin during pregnancy tended to weigh more than the children whose mothers took the placebo. Although metformin did not appear to affect birth weight, the trend became apparent when children reached six months of age. At the age of four years, the children in the metformin group had higher BMI scores and were more likely to meet the criteria for obesity or overweight than children in the placebo group.
"Few studies have examined the long-term health of children born to women with PCOS who took metformin," Hanem said. "Our findings indicate more research is needed to determine its effects on children who were exposed in the womb."

FDA-approved drug to treat high blood pressure increases life span in worms

Skeletal formula of hydralazine
UT Southwestern Medical Center researchers find that an FDA-approved drug to treat high blood pressure seems to extend life span in worms via a cell signaling pathway that may mimic caloric restriction.
The drug, hydralazine, extended life span about 25 percent in two strains of C. elegans(roundworms), one a wild type and the other bred to generate high levels of a neurotoxic protein called tau that in humans is associated with Alzheimer's disease.
"This is the first report of hydralazine treatment activating the NRF2/SKN-1 signaling pathway. We found the drug extends the life span of worms as well as or better than other potential anti-aging compounds such as curcumin and metformin. The treatment also appeared to maintain their health as measured by tests of flexibility and wiggling speed," said Dr. Hamid Mirzaei, Assistant Professor of Biochemistry at UT Southwestern and senior author of the study, published today in Nature Communications.
The NRF2 pathway protects human cells from oxidative stress. The body's ability to protect itself against damaging oxygen free radicals diminishes with age, he said.
One of the hallmarks of aging and neurodegenerative diseases such as Alzheimer's and Parkinson's is oxidative stress, which is believed to result cumulatively from inflammatory and infectious illnesses throughout life, Dr. Mirzaei explained. SKN-1, a C. eleganstranscription factor, corresponds to NRF2 in humans. Both play a pivotal role in their respective species' responses to oxidative stress and life span, he said.
The UT Southwestern researchers were searching for a chemical probe they could use in experiments to identify proteins that get oxidized and become toxic during aging. Their screen for a substance that would cross the blood-brain barrier and be nontoxic led them to hydralazine.
"Age-related neurodegenerative diseases are devastating, and those conditions are on the rise due to the increase in the life span of humans. For that reason, it is important to develop treatments to maintain human health as long as possible," said Dr. Mirzaei, who is also an investigator in the Center for Alzheimer's and Neurodegenerative Diseases, part of the Peter O'Donnell Jr. Brain Institute at UT Southwestern.

FDA Approves Once-Weekly Bydureon BCise (exenatide) for Patients with Type-2 Diabetes








 In continuation of my update on exenatide. AstraZeneca announced that the US Food and Drug Administration (FDA) has approved Bydureon® BCise™ (exenatide extended-release) injectable suspension, a new formulation of Bydureon (exenatide extended-release) injectable suspension in an improved once-weekly, single-dose autoinjector device for adults with type-2 diabeteswhose blood sugar remains uncontrolled on one or more oral medicines inaddition to diet and exercise, to improve glycemic control.

Unlike other glucagon-like peptide-1 (GLP-1) receptor agonists, Bydureon BCise has a unique, continuous-release microsphere delivery system designed to provide consistent therapeutic levels of the active ingredient, exenatide, to help patients reach and maintain steady state. The new formulation in the innovative Bydureon BCise device is proven to reduce blood sugar levels, with the added benefit of weight loss, although not a weight loss medicine.

Across two clinical trials, average HbA1c reductions of up to 1.4% and average weight loss of up to 3.1 pounds were achieved when used as  monotherapy or as an add-on to metformin, a sulfonylurea, a thiazolidinedione, or any combination of two of these oral anti-diabetic medicines at 28 weeks. The most common adverse reactions reported in ≥5% of patients in clinical trials were nausea (8.2%) and adverse events associated with injection-s te nodules (10.5%).

Bydureon BCise is designed for ease and patient convenience in a once-weekly, pre-filled device with a pre-attached hidden needle. The medication is administered in three simple steps – mix, unlock, inject.

A combination of a diabetes medication and an antihypertensive drug can effectively combat cancer cells. The team of researchers led by Prof. Michael Hall at the Biozentrum of the University of Basel has also reported that specific cancer cells respond to this combination of drugs. The results of the study have now been published in "Science Advances".

Metformin is the most widely prescribed drug for the treatment of type 2 diabetes. Besides its blood sugar lowering effect, it also displays anti-cancer properties. The usual therapeutic dose, however, is too low to effectively fight cancer. The research team led by Prof. Michael Hall, at the Biozentrum of the University of Basel, has now made an unexpected discovery: The antihypertensive drug syrosingopine potentiates the anti-cancer efficacy of metformin. Apparently, this drug combination drives cancer cells to programmed "suicide".

Drug cocktail kills tumor cells

At higher doses, the antidiabetic drug inhibits the growth of cancer cells but could also induce unwanted side effects. Therefore, the researchers screened over a thousand drugs for whether they can enhance the anticancer action of metformin. A favorite emerged from this screening: Syrosingopine, an antihypertensive drug. As the study shows, the cocktail of these two drugs is effective in a wide range of cancers.

"For example, in samples from leukemia patients, we demonstrated that almost all tumor cells were killed by this cocktail and at doses that are actually not toxic to normal cells", says the first author, Don Benjamin. "And the effect was exclusively confined to cancer cells, as the blood cells from healthy donors were insensitive to the treatment."

Drugs block "juice" supply to cancer cells

In mice with malignant liver cancer, enlargement of the liver was reduced after the therapy. Also the number of tumor nodules was less - in some animals the tumors disappeared completely. A glance at the molecular processes in the tumor cells explains the drug combination's efficacy: Metformin lowers not only the blood glucose level, but also blocks the respiratory chain in the energy factories of the cell, the mitochondria. The antihypertensive drug syrosingopine inhibits, among other things, the degradation of sugars.

Thus, the drugs interrupt the vital processes which provide energy for the cell. Due to their increased metabolic activity and rapid growth, cancer cells have a particularly high energy consumption, which makes them extremely vulnerable when the energy supply is reduced.
Groundbreaking step towards clinical application

By testing a range of other compounds with the same mode of action, the scientists could demonstrate that the inhibition of the respiratory chain in the mitochondria is a key mechanism. These also reduced cancer cell growth in combination with the antihypertensive drug.

"We have been able to show that the two known drugs lead to more profound effects on cancer cell proliferation than each drug alone," explains Benjamin. "The data from this study support the development of combination approaches for the treatment of cancer patients." This study may have implications for future clinical application of combination scenarios targeting the energy needs of tumor cells.

Oral antidiabetic drug modulates the body's nitrogen and urea metabolism

In continuation of my updates on metformin

Metformin.svg

The most frequently prescribed oral antidiabetic drug metformin significantly affects metabolic pathways. This was reported by scientists from the Helmholtz Zentrum München together with colleagues from the German Diabetes Center (DDZ) in Düsseldorf. The underlying study was conducted with further scientists of the German Center for Diabetes Research (DZD). These results have now been published in the journal 'Diabetes'.

Metformin is a widespread oral medication to increase insulin sensitivity in patients with type 2 diabetes (T2D). According to a number of studies, it additionally reduces the risk of cardiovascular complications. Last year, a team led by Dr. Rui Wang-Sattler discovered that metformin intake lowers the levels of the harmful LDL cholesterol by activating the AMPK protein complex. Dr. Wang-Sattler is head of the "Metabolism" research group in the Research Unit of Molecular Epidemiology at the Institute of Epidemiology II at the Helmholtz Zentrum München. Her group aims to understand the molecular mechanisms that underlie the activity of metformin.

Metformin intake changes metabolite profiles in population-based KORA study
In the present work, the interdisciplinary team of scientists was able to explain a further feature of the drug: "Our results show that metformin also modulates the body's nitrogen and urea metabolism," first author Jonathan Adam summarizes.

In close collaboration with Dr. Stefan Brandmaier and other colleagues, he examined the metabolite profiles (353 small molecules) of KORA participants. The researchers compared T2D patients treated with metformin (a total of 74) with those not being treated with metformin (115) and looked for differences in the distribution of metabolites in the blood. They subsequently confirmed the findings in samples of more than 1500 participants.
Amino acid levels provide a crucial hint

Changes in the amino acid citrulline concentration caused by metformin intake were particularly significant. The amino acid citrulline (named after Citrullus vulgaris, the watermelon, where it is found in large quantities) showed significantly lower levels in samples of T2D patients treated with metformin than in untreated ones. The researchers propose that this is a further consequence of metformin's AMPK activation. "Our analysis indicates that the activation of the AMPK pathway by metformin affects nitrogen and urea metabolism through a further enzyme, which thus lowers the citrulline levels", reports Rui Wang-Sattler.

Accordingly, the scientists suspect that the additional intake of citrulline could have a positive effect on the cardiovascular system in patients being treated with metformin. As a follow-up study, the team plans to analyze the metformin-associated effects on other central metabolic pathways, such as the citric acid cycle.
