FDA Approves Inluriyo (imlunestrant) for Adults with ER+, HER2-, ESR1-Mutated Advanced or Metastatic Breast Cancer

Eli Lilly and Company (NYSE: LLY) announced  the U.S. Food and Drug Administration (FDA)  approval of  Inluriyo (imlunestrant, 200 mg tablets), an oral estrogen receptor antagonist, for the treatment of adults with estrogen receptor-positive (ER+), human epidermal growth factor receptor 2-negative (HER2–), ESR1-mutated advanced or metastatic breast cancer (MBC) whose disease progressed after at least one line of endocrine therapy (ET). In the Phase 3 EMBER-3 trial, Inluriyo reduced the risk of progression or death by 38% versus ET. Among patients with ESR1-mutated MBC, Inluriyo significantly improved progression-free survival (PFS) versus fulvestrant or exemestane, with a median PFS of 5.5 months vs 3.8 months (HR=0.62 [95% CI: 0.46-0.82]); p-value=0.0008.

Inluriyo is a treatment for ER+, HER2–, ESR1-mutated MBC. Some breast cancers develop ESR1 mutations that can cause estrogen receptors to become overactive and drive cancer growth. Inluriyo binds, blocks, and facilitates the degradation of these receptors, helping to slow disease progression. Its once-daily dosing provides patients with an oral treatment option.

"This therapy reflects our commitment to developing treatments that improve outcomes for people with breast cancer and represents an important step toward advancing innovative, all-oral treatment approaches," said Jacob Van Naarden, executive vice president and president of Lilly Oncology. "We are deeply grateful to the patients, investigators, Lilly team members and clinical care teams who made this advancement possible. This therapy has the potential to make the treatment journey more manageable for those living with breast cancer."

The Inluriyo label contains a warning and precaution for embryo-fetal toxicity.

The FDA approval is based on the results of the EMBER-3 trial in the patient population harboring ESR1-mutated MBC (n=256). Patients received Inluriyo or ET as first-line treatment for MBC following recurrence on adjuvant aromatase inhibitor (AI), +/- prior CDK4/6 inhibitor (21%), or as second-line treatment for MBC following progression on AI, +/- prior CDK4/6 inhibitor (79%).

"This represents an important advancement for patients with ESR1-mutated MBC, a mutation found in nearly half of patients who have taken hormone therapies, often contributing to treatment resistance," said Komal Jhaveri, M.D., FACP, FASCO, section head of Endocrine Therapy Research and clinical director of Early Drug Development at Memorial Sloan Kettering Cancer Center, and a principal investigator of EMBER-3. "With its demonstrated efficacy, tolerability profile and oral administration, this therapy provides a meaningful alternative treatment option for this patient population."

In EMBER-3, the majority of adverse events (AEs) with Inluriyo were low grade (Grade 1-2) and the most common adverse reactions (≥10%), including laboratory abnormalities, were hemoglobin decreased, musculoskeletal pain, calcium decreased, neutrophils decreased, AST increased, fatigue, diarrhea, ALT increased, triglycerides increased, nausea, platelets decreased, constipation, cholesterol increased, and abdominal pain. In the study, 4.6% of patients permanently discontinued treatment due to AEs. Dose reductions and dose interruptions occurred in 2.4% and 10% of patients, respectively.

"The approval of Inluriyo expands the metastatic breast cancer treatment landscape for patients who test positive for the ESR1 mutation," said Jean Sachs, CEO, Living Beyond Breast Cancer. "Eligible patients will now have access to an additional treatment option, offering them the potential for flexibility in their daily lives and disease management, and—above all—renewed hope for the future."

Inluriyo is also being studied in the ongoing Phase 3 EMBER-4 trial in the adjuvant setting for people with ER+, HER2– early breast cancer (EBC) at increased risk of recurrence, which is enrolling approximately 8,000 patients worldwide.

FDA Grants Accelerated Approval for Rezdiffra (resmetirom) for the Treatment of Patients with Noncirrhotic Nonalcoholic Steatohepatitis (NASH)

Madrigal Pharmaceuticals, Inc. (NASDAQ:MDGL), a biopharmaceutical company focused on delivering novel therapeutics for nonalcoholic steatohepatitis (NASH),  announced the U.S. Food and Drug Administration (FDA)  accelerated approval for Rezdiffra (resmetirom) in conjunction with diet and exercise for the treatment of adults with noncirrhotic NASH with moderate to advanced liver fibrosis (consistent with stages F2 to F3 fibrosis). Continued approval for this indication may be contingent upon verification and description of clinical benefit in ongoing confirmatory trials.

Bill Sibold, Chief Executive Officer of Madrigal, stated, “NASH with moderate to advanced liver fibrosis is a serious and progressive liver disease that, until now, has not had an FDA-approved therapy. The accelerated approval of Rezdiffra is a culmination of more than 15 years of research from our founder Dr. Becky Taub and a small R&D team that took on one of the biggest challenges in drug development. This is a historic moment for the NASH field and represents the best of what our industry is capable of. We’re excited to deliver Rezdiffra to patients in need.”

Becky Taub, M.D., the Founder, Chief Medical Officer and President of Research & Development of Madrigal, stated, “Madrigal would like to thank the many patients who made the accelerated approval of Rezdiffra possible by participating in our clinical studies. We believe Rezdiffra will change the treatment paradigm for NASH with moderate to advanced liver fibrosis, giving physicians a liver-directed therapy to help improve fibrosis and resolve NASH before their patients progress to cirrhosis.”

Wayne Eskridge, Co-Founder and Chief Executive Officer of the Fatty Liver Foundation, stated, “This is a day of celebration for patients with NASH who have been waiting many years for the first approved therapy. I believe this approval milestone will bring new energy and momentum to the NASH community, accelerating our efforts to improve disease education, build care pathways, and expand investment in NASH research.”

Rezdiffra is a once-daily, oral THR-β agonist designed to target key underlying causes of NASH. The accelerated approval of Rezdiffra was based on results from the Phase 3 MAESTRO-NASH trial, which was recently published in the New England Journal of Medicine. MAESTRO-NASH is an ongoing pivotal, multicenter, randomized, double-blind, placebo-controlled trial that enrolled 1,759 patients with biopsy-confirmed NASH. Following 52 weeks of treatment, both 100 mg and 80 mg doses of Rezdiffra demonstrated statistically significant improvement compared to placebo on two primary endpoints: NASH resolution (including a reduction in the nonalcoholic fatty liver disease [NAFLD] activity score by ≥2 points) with no worsening of fibrosis, and an improvement in fibrosis by at least one stage with no worsening of the NAFLD activity score. Fibrosis improvement and NASH resolution were consistent regardless of age, gender, type 2 diabetes status, or fibrosis stage.

The Rezdiffra prescribing information does not include a liver biopsy requirement for diagnosis. The recommended dosage of Rezdiffra is based on actual body weight. For patients weighing <100 kg (220 lbs.), the recommended dosage is 80 mg orally once daily. For patients weighing ≥100 kg (220 lbs.), the recommended dosage is 100 mg orally once daily.

Stephen Harrison, M.D., Chairman for both Pinnacle Clinical Research and Summit Clinical Research, San Antonio, Texas, Visiting Professor of Hepatology, Oxford University, and lead Principal Investigator of the MAESTRO studies, commented, “The approval of the first medication for NASH is a true game-changer for healthcare providers, the research community and, most importantly, patients living with this serious liver condition. Based on the robust efficacy and safety data generated in two large Phase 3 MAESTRO studies, I believe Rezdiffra will become the foundational therapy for patients with NASH with moderate to advanced liver fibrosis.”

Dr. Harrison continued, “Importantly, we continue to study Rezdiffra to determine if the positive results observed in the MAESTRO studies will lead to reduced risk of progression to cirrhosis, liver failure, need for liver transplant and premature mortality.”

MAESTRO-NASH remains ongoing as an outcomes study designed to generate confirmatory data that, if positive, will help verify clinical benefit and may support full approval. A second ongoing outcomes trial is evaluating progression to liver decompensation events in patients with well-compensated NASH cirrhosis treated with Rezdiffra versus placebo.

Rezdiffra should not be used in patients with decompensated cirrhosis. The most common adverse reactions reported in patients treated with Rezdiffra included diarrhea, nausea, pruritis, abdominal pain, vomiting, constipation, and dizziness. Diarrhea and nausea typically began early in treatment initiation and were mild to moderate in severity. A separate, noninvasive Phase 3 trial, MAESTRO-NAFLD-1, evaluated the safety and tolerability of Rezdiffra and contributed to the safety database supporting regulatory benefit-risk assessment.

Rezdiffra is expected to be available to patients in the U.S. in April and will be distributed through a limited specialty pharmacy network. Madrigal is committed to helping appropriate patients who may benefit from Rezdiffra access the medication through the Madrigal Patient Support program. This program is designed to help patients navigate insurance and affordability challenges and provide co-pay support for eligible patients. Madrigal has also established a patient assistance program (PAP) to help patients with no insurance access Rezdiffra.

Phase 3 MAESTRO-NASH Trial Results

MAESTRO-NASH is an ongoing Phase 3 trial that enrolled 1759 patients with biopsy-confirmed NASH. Patients were randomly assigned in a 1:1:1 ratio to receive once-daily Rezdiffra at a dose of 80 mg or 100 mg or placebo. The two primary endpoints at week 52 were NASH resolution with no worsening of fibrosis and an improvement in fibrosis by at least one stage with no worsening of the NAFLD activity score. The key secondary endpoint was the percent change from baseline in LDL cholesterol at week 24.

Rezdiffra achieved both primary endpoints and the key secondary endpoint of the MAESTRO-NASH trial. Additionally, Rezdiffra improved liver enzymes, fibrosis biomarkers and imaging tests as compared with placebo. The primary results of the trial were published in the New England Journal of Medicine in February 2024.

Patients enrolled in the MAESTRO-NASH trial continue on therapy after the initial 52-week treatment period for up to 54 months to accrue and measure hepatic clinical outcome events including progression to cirrhosis on biopsy and hepatic decompensation events, as well as all-cause mortality. The 54-month outcomes portion of the trial is designed to generate confirmatory data that, if positive, will help verify Rezdiffra’s clinical benefit and may support full approval.

FDA Approves Zepbound (tirzepatide) for Chronic Weight Management

• 
• The U.S. Food and Drug Administration (FDA) approved Eli Lilly and Company's (NYSE: LLY) Zepbound™ (tirzepatide) injection, the first and only obesity treatment of its kind that activates both GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 (glucagon-like peptide-1) hormone receptors. Zepbound is indicated for adults with obesity (with a BMI of 30 kg/m2 or greater), or those who are overweight (with a BMI of 27 kg/m2 or greater) and also have weight-related medical problems such as hypertension, dyslipidemia, type 2 diabetes mellitus, obstructive sleep apnea or cardiovascular disease, to lose weight and keep it off. It should be used with a reduced-calorie diet and increased physical activity. Zepbound should not be used with other tirzepatide-containing products or any GLP-1 receptor agonist medicines, and it has not been studied in patients with a history of pancreatitis, or with severe gastrointestinal disease, including severe gastroparesis.
• "Obesity is a chronic disease that can result in serious health complications, including heart disease, stroke and diabetes. Despite our knowledge of obesity as a treatable, chronic disease, people living with obesity still face many challenges in their health and weight management journey," said Joe Nadglowski, president and chief executive officer of the Obesity Action Coalition. "New treatment options bring hope to the many people with obesity who struggle with this disease and are seeking better options for weight management."
• The approval was based on results from the phase 3 SURMOUNT-1 and SURMOUNT-2 trials. In SURMOUNT-1, a study in 2,539 adults with obesity, or excess weight and weight-related medical problems not including diabetes, people taking Zepbound as an adjunct to diet and exercise experienced substantial weight loss compared with placebo at 72 weeks. At the highest dose (15 mg), people taking Zepbound lost on average 48 lb., while at the lowest dose (5 mg), people lost on average 34 lb. (compared to 7 lb. on placebo).
• Additionally, 1 in 3 patients taking Zepbound at the highest dose lost over 58 lb. (25% of body weight), compared to 1.5% on placebo, according to data not controlled for type 1 error. The average starting weight was 231 lb.
• While not approved to treat these conditions, in a clinical trial, people who dieted, exercised and took Zepbound for the treatment of obesity or overweight with weight-related medical problems observed changes in cholesterol and reductions in blood pressure and waist size.
• "Unfortunately, despite scientific evidence to the contrary, obesity is often seen as a lifestyle choice – something that people should manage themselves," said Dr. Leonard Glass, senior vice president global medical affairs, Lilly Diabetes and Obesity. "For decades, diet and exercise have been a go-to, but it's not uncommon for a person to have tried 20-30 times to lose weight with this approach. Research now shows that the body may respond to a calorie-deficit diet by increasing hunger and reducing feelings of fullness, making weight loss more difficult. Lilly is aiming to eliminate misperceptions about this disease and transform how it can be managed."
• Zepbound use may be associated with gastrointestinal adverse reactions, sometimes severe. The most commonly reported adverse events (observed in ≥ 5% of clinical trial participants) were nausea, diarrhea, vomiting, constipation, abdominal pain, dyspepsia, injection-site reactions, fatigue, hypersensitivity reactions, eructation, hair loss and gastroesophageal reflux disease.1 In studies, most nausea, diarrhea and vomiting occurred when people increased their dose – but the effects generally decreased over time. In studies, gastrointestinal side effects were more common in people taking Zepbound than people taking placebo, and people taking Zepbound were more likely than those on placebo to stop treatment because of these side effects. The label for Zepbound includes a Boxed Warning regarding thyroid C-cell tumors. Zepbound is contraindicated in patients with a personal or family history of medullary thyroid carcinoma, in patients with Multiple Endocrine Neoplasia syndrome type 2, and in patients with known serious hypersensitivity to tirzepatide or any of the excipients in Zepbound. See Important Safety Information below and full Prescribing Information and Medication Guide.
• "Far too many hurdles continue to prevent people living with obesity from accessing obesity treatments that could lead to significant weight loss," said Mike Mason, executive vice president and president, Lilly Diabetes and Obesity. "Broader access to these medicines is critical, which is why Lilly is committed to working with healthcare, government and industry partners to ensure people who may benefit from Zepbound can access it."
• Zepbound is expected to be available in the U.S. by the end of the year in six doses (2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, 15 mg) at a list price of $1,059.87, which is approximately 20% lower than semaglutide 2.4 mg injection for weight loss. List price does not reflect the typical out-of-pocket cost to patients given insurance coverage and discounts. Lilly is putting a commercial savings card program in place that will help people who may benefit from Zepbound better access it.

• People who are commercially insured with coverage for Zepbound may be eligible to pay as low as $25 for a 1-month or 3-month prescription.
• People who are commercially insured without coverage for Zepbound may be eligible to pay as low as $550 for a 1-month prescription of Zepbound, approximately 50% lower than the list price.
• People may begin using the savings card program in the days following product availability at U.S. pharmacies. To learn more about these programs, or to sign up to receive the latest news, please visit www.Zepbound.lilly.com. Terms and conditions apply.
• Tirzepatide is also under regulatory review for weight management in Europe, China, the United Kingdom and several additional markets.

FDA Approves Leqvio (inclisiran), First-in-Class siRNA to Reduce Low-Density Lipoprotein Cholesterol (LDL-C)

                       In continuation of my update on inclisiran

                             Novartis today announced the US Food and Drug Administration (FDA) approval of Leqvio® (inclisiran), the first and only small interfering RNA (siRNA) therapy to lower low-density lipoprotein cholesterol (also known as bad cholesterol or LDL-C) with two doses a year, after an initial dose and one at three months.

"Leqvio is a revolutionary approach to lower LDL-C, and creates new possibilities for how  healthcare systems can impact cardiovascular disease, a defining public health challenge of our time," said Vas Narasimhan, Novartis CEO. "We now have the opportunity, working together with partners, to provide this first-ever approved LDL-C–lowering siRNA-based therapy to tackle ASCVD at scale across the United States."

Leqvio is indicated in the United States as an adjunct to diet and maximally tolerated statin therapy for the treatment of adults with clinical atherosclerotic cardiovascular disease (ASCVD) or heterozygous familial hypercholesterolemia (HeFH) who require additional lowering of LDL-C. The effect of Leqvio on cardiovascular morbidity and mortality is being explored in clinical trials currently underway.

"ASCVD is a substantial public health burden affecting 30 million Americans," said Norman Lepor, MD, a Los Angeles based cardiologist and a clinical investigator in the Phase III clinical program for Leqvio. "As a first-of-its-kind siRNA therapy, Leqvio works differently than other cholesterol treatments, with twice-yearly dosing that makes it a compelling option for the millions of people with ASCVD already on cholesterol-lowering medications struggling to reach their LDL-C target."

Leqvio reduces the amount of LDL-C in the bloodstream by improving the liver's natural ability to prevent the production of a protein that plays a role in keeping circulating cholesterol levels high6,7. It is a subcutaneous injection given by a healthcare provider with an initial dose, then again at three months, and then every six months1. This approach may help those who have trouble sticking to medicines that are self-administered and have greater dosing frequency. Leqvio will be available in early January 2022.

"People with ASCVD have most likely experienced a heart attack or stroke from high cholesterol, causing a burden on the family and having a negative impact on lives," said Andrea Baer, Executive Director of The Mended Hearts, Inc. "One of the first steps to improving patients' health is to manage high cholesterol and we're encouraged that this new twice-a-year treatment offers a new option." 

The FDA approval was based on results from the comprehensive Phase III ORION-9, -10 and -11 clinical trials, in which all 3,457 participants with ASCVD or HeFH had elevated LDL-C while receiving a maximally tolerated dose of statin therapy2,3. In the Phase III trials at month 17, Leqvio delivered effective and sustained LDL-C reduction of up to 52% vs. placebo and was reported to be well-tolerated with a safety profile shown to be comparable to placebo2,3. The most common side effects were mild to moderate injection site reaction (including pain, redness and rash), joint pain, urinary tract infection, diarrhea, chest cold, pain in legs or arms and shortness of breath2,3.

Novartis has obtained global rights to develop, manufacture and commercialize Leqvio under a license and collaboration agreement with Alnylam Pharmaceuticals, a leader in RNAi therapeutics.

FDA Approves Roszet (rosuvastatin and ezetimibe) to Reduce LDL-C in Hyperlipidemia and Homozygous Familial Hypercholesterolemia

Althera Pharmaceuticals, a company focused on heart health, announced the FDA approval of Roszet (rosuvastatin and ezetimibe) tablets, as an adjunct to diet, for treatment of elevated low-density lipoprotein cholesterol (LDL-C) in adult patients with primary non-familial hyperlipidemia and in adult patients with homozygous familial hypercholesterolemia. Roszet contains rosuvastatin, a powerful statin for LDL-C reduction, and ezetimibe, an efficacious cholesterol absorption inhibitor. The two components work through distinct but complimentary mechanisms to give Roszet the power to significantly lower LDL-C.

  

“The optimal LDL-C levels in guidelines across the world have been shifting lower and now many patients need to get their LDL-C below 70 mg/dL,” said Dr. Christie Ballantyne, Chief of Cardiology and Cardiovascular Research at Baylor College of Medicine. “These levels can be quite difficult to achieve with just a statin on top of diet and exercise. Rosuvastatin and ezetimibe have been extensively studied in combination therapy and have been shown to significantly reduce LDL cholesterol beyond the statin alone. Combination therapy has been widely used in hypertension to achieve lower blood pressure targets. This new therapy provides a high efficacy statin plus ezetimibe in a single once daily pill which is a powerful new option to help get patients to the desirable LDL goal without increasing pill burden or requiring addition of injectable therapies”

"With Roszet’s approval in the U.S., we reaffirm our commitment to improving cholesterol treatment options for physicians and patients," said Sanjeev Agarwal, CEO of Althera Pharmaceuticals. "We are on a mission to positively impact patients’ health. By making this highly effective medicine available and affordable, we hope to improve the long-term health of patients, including those with prior cardiovascular disease.”

While a patient's out-of-pocket costs will vary depending on insurance status, the Roszet Savings Program aims to reduce co-pays to as little as $20 per month for eligible patients with commercial insurance coverage. Althera is continuing to work with all stakeholders to ensure that Roszet is affordable and accessible to all. Please visit http://www.roszet.com for more information and updates about the Roszet Savings Program and eligibility.

Availability

Roszet will be available in pharmacies in June 2021.

Roszet Indications, Dosage and Other Select Information

Roszet is indicated, as an adjunct to diet, in adults with primary non-familial hyperlipidemia to reduce low-density lipoprotein cholesterol (LDL-C), and alone or as an adjunct to other LDL-C lowering therapies in adults with homozygous familial hypercholesterolemia (HoFH) to reduce LDL-C.

Roszet is available as a once-daily tablet with rosuvastatin/ezetimibe dosages of 5 mg/10 mg, 10 mg/10 mg, 20 mg/10 mg and 40 mg/10 mg.

FDA Approves Nextstellis (drospirenone and estetrol) Oral Contraceptive for Birth Control

In continuation of my update on drospirenone

"When speaking with patients about their contraceptive options, one of the most common concerns is side effects," said Mitchell Creinin, Professor and Director of Family Planning at the University of California, Davis. "Nextstellis is an innovative contraceptive that has been shown to be not only safe and effective, but also well tolerated in clinical trials with a desirable bleeding profile and minimal impact on triglycerides, cholesterol, and glucose, as well as weight and endocrine markers."

Nearly 10 million American women use short-acting combination contraceptives (estrogen and progestin). Of these contraceptives, more than 99% contain ethinyl estradiol (EE), a synthetic estrogen that binds widely to all estrogen receptors in the body.
Nextstellis is the only oral contraceptive to contain E4; E4 acts differently than other estrogens and is the first estrogen to be described as a NEST:  A Native Estrogen with Selective actions in Tissues. It has more selective activity in tissues, focusing on those needed to support contraceptive efficacy, cycle control and other beneficial effects of estrogen. Nextstellis pairs E4, which has a long half-life (24-28 hours), with the proven progestin drospirenone, specifically chosen due to its long half-life (~30 hours) and its anti-androgenic and anti-mineralocorticoid properties.

"The approval of Nextstellis represents an important milestone in providing women with another choice for their reproductive health," said Scott Richards, CEO of Mayne Pharma. "We are delighted to be introducing a new estrogen and bringing to market this novel, safe and effective option for women to consider with their healthcare providers."

The comprehensive Nextstellis clinical study program included a diverse patient population with women both starting and switching birth control as well as patients with a body mass index (BMI) of up to 35 kg/m2. According to phase 3 study findings, Nextstellis demonstrated contraceptive efficacy across all subgroups by age, BMI and prior hormonal contraception use. Nextstellis was also associated with a favorable bleeding profile and low rates of breakthrough bleeding, including in cycle 1.

Nextstellis was developed by Mayne Pharma's development and manufacturing partner, Mithra Pharmaceuticals, SA. The company anticipates the commercial launch of Nextstellis by the end of June 2021.

Mayne Pharma announced today that the U.S. Food and Drug Administration (FDA) has approved Nextstellis (3 mg drospirenone [DRSP] and 14.2 mg estetrol [E4] tablets) for the prevention of pregnancy. Nextstellis is the first and only contraceptive pill containing E4, a naturally occurring estrogen, now produced from a plant source, with a unique mechanism of action that offers potential advantages over other estrogens.

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

In continuation of my update on 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.

Chemical found in drinking water linked to tooth decay in children

Children with higher concentrations of a certain chemical in their blood are more likely to get cavities, according to a new study by West Virginia University School of Dentistry researchers.

Manufactured chemical g roups called perfluoroalkyl and polyfluoroalkyl substances are universal as a result of extensive manufacturing and use. Although manufacturers no longer use PFAS to make nonstick cookware, carpet, cardboard and other products, they persist in the environment. Scientists have linked them to a range of health problems—from heart disease to high cholesterol—but now R. Constance Wiener and Christopher Waters are exploring how they affect dental health.

They investigated whether higher concentrations of PFAS were associated with greater tooth decay in children. One of them—perfluorodecanoic acid—was linked to dental cavities. Their findings appear in the Journal of Public Health Dentistry.

"Due to the strong chemical bonds of PFAS, it is difficult for them to breakdown, which makes them more likely to be persistent within the environment, especially in drinking water systems," said Waters, who directs the School of Dentistry's research labs. "A majority of people may not be aware that they are using water and other products that contain PFAS."

The 629 children who participated in the study were 3 to 11 years old and were part of the National Health and Nutrition Examination Survey. Samples of the children's blood were analyzed for PFAS in 2013 and 2014. Their tooth decay and other factors—such as their race, their BMI and how often they brushed their teeth—were assessed.

Of the seven PFAS that Wiener and Waters analyzed, perfluorodecanoic acid was the one that correlated with higher levels of tooth decay.

"Perfluorodecanoic acid, in particular, has a long molecular structure and strong chemical bonds; therefore, it remains in the environment longer. As a result, it is more likely to have negative health consequences such as dental caries," said Dr. Wiener, an associate professor in the Department of Dental Practice and Rural Health.

But how does that influence happen? Wiener and Waters have a hypothesis. According to other research, perfluorodecanoic acid may disrupt the healthy development of enamel, which is what makes teeth hard. That disruption can leave teeth susceptible to decay.

However, when it comes to cavities, scientists haven't parsed perfluorodecanoic acid's mechanism of action yet. The topic warrants further investigation.

"While the findings of this study are important, there are some study limitations, and more work is needed to fully understand how this molecule impacts normal tooth formation," said Fotinos Panagakos, the School of Dentistry's vice dean for administration and research.

"The good news is that, in our study, about half of the children did not have any measurable amount of PFAS. Perhaps this is due to certain PFAS no longer being made in the US," Wiener said.

Another piece of good news is that the study reaffirmed the importance of dental hygiene and checkups. Children who brushed once a day or less frequently had significantly higher tooth decay than those who brushed at least twice daily.

Likewise, children who had not been to the dentist within the previous year were twice as likely to have higher rates of tooth decay than kids who hadn't.

So, even though parents cannot control what is in their children's drinking water, they can still protect their children's teeth by fostering thorough, regular brushing and scheduling dental exams.

The School of Dentistry will hold Give Kids a Smile Day on Friday, Feb. 7, at the Pediatric Dentistry Clinic. Dental students will treat more than 100 children for free that day. Each visit includes an exam, a cleaning, a fluoride treatment and—if appropriate—X-rays.

AHA: Adding Omega-3 Fatty Acids Does Not Cut High CV Risk

In continuation of my update on omega-3 fatty acids

A carboxylic acid formulation of eicosapentaenoic acid and docosahexaenoic acid (omega-3 CA) does not improve outcomes among statin-treated patients at high cardiovascular risk, according to a study published online Nov. 15 in the Journal of the American Medical Association to coincide with the American Heart Association Scientific Sessions 2020, held virtually from Nov. 13 to 17.

Stephen J. Nicholls, M.B.B.S., Ph.D., from Monash University in Melbourne, Australia, and colleagues conducted a double-blind trial comparing omega-3 CA to corn oil in 13,078 statin-treated patients with high cardiovascular risk, hypertriglyceridemia, and low high-density lipoprotein cholesterol from 675 academic and community hospitals in 22 countries. Participants were randomly assigned in a 1:1 ratio to either 4 g/day omega-3 CA or corn oil (6,539 to each) in addition to usual background therapies, including statins.

The trial was halted prematurely based on an interim analysis indicating low probability of clinical benefit of omega-3 CA, when 1,384 patients had experienced a primary end-point event. The researchers found that the primary end point (composite of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization, or unstable angina requiring hospitalization) occurred in 12.0 and 12.2 percent of those treated with omega-3 CA and corn oil, respectively (hazard ratio, 0.99; 95 percent confidence interval, 0.90 to 1.09; P = 0.84).

"These findings do not support use of this omega-3 fatty acid formulation to reduce major adverse cardiovascular events in high-risk patients," the authors write.

Several authors disclosed financial ties to pharmaceutical companies, including AstraZeneca, which funded the study.

Early treatment with lorlatinib improves survival in some lung cancer patients: Lung cancer patients with a specific genetic alteration lived longer and were protected against metastasis to the brain when treated early with lorlatinib

In continuation of my update on Lorlatinib

Non-small-cell lung cancer (NSCLC) accounts for 87% of all cases of lung cancer. Some 5% of NSCLC cases are ALK-positive, which means they have a genetic abnormality in the anaplastic lymphoma kinase gene. ALK-positive NSCLC, which is not associated with smoking, is a particularly aggressive form of lung cancer.

"When ALK is turned on abnormally, it's like stepping on the gas pedal -- it drives uncontrolled proliferation and survival of cancer cells," says investigator Alice Shaw, MD, PhD, who was formerly director of the Center for Thoracic Cancers at MGH and led the NEJM study. Notably, ALK-positive patients tend to be 10 to 15 years younger than other lung cancer patients. They are also at high risk for developing brain metastasis.

A new class of drugs that block ALK, known as ALK inhibitors, was discovered in 2008. "Turning off ALK with an ALK inhibitor is like putting on the brakes," agrees Justin Gainor, MD, of the Mass General Cancer Center, who worked with Shaw on the study. "It can lead to rapid killing of cancer cells and cause tumors to shrink dramatically." Both first and second generation ALK inhibitors have been developed, including crizotinib (Xalkori), alectinib (Alecensa), and brigatinib (Alunbrig), which can be very effective, but patients eventually relapse. What's more, patients treated with these drugs can still develop metastatic spread of cancer to the brain.

Lorlatinib belongs to a third-generation of this drug class and is even more effective at blocking ALK. It's currently approved by the Food and Drug Administration for treating ALK-positive patients whose cancer has progressed despite taking older-generation ALK inhibitors.

Shaw and her co-investigators wanted to know if lorlatinib improved the likelihood of long-term remission in ALK-positive patients when administered as first-line therapy. To find out, she and colleagues at 104 medical centers in 23 countries recruited 296 patients with advanced, previously untreated ALK-positive NSCLC. Half of the patients received lorlatinib, while the remainder were treated with crizotinib, which was the standard of care for these patients when the trial began.

The results were striking. Compared to patients who received crizotinib, those given lorlatinib had a 72% reduction in the risk of cancer progression or death. Importantly, lorlatinib also reduced the risk of new or recurrent brain metastases by 93%. Serious side effects were more common in the lorlatinib group, but more than half were increases in blood cholesterol and triglycerides, which were manageable with medication.

The investigators will continue to follow patients in this study to track their long-term outcomes, but "these results support lorlatinib as a potential first-line option for ALK-positive patients," says Shaw.

Shaw is now global head of Translational Clinical Oncology at the Novartis Institutes for BioMedical Research

Walnuts may slow cognitive decline in at-risk elderly: Two-year study examined walnut consumption among study groups in California and Spain

In continuation of my update on Walnuts

Eating walnuts may help slow cognitive decline in at-risk groups of the elderly population, according to a study conducted by researchers in California and Spain.

The Walnuts and Healthy Aging Study, published this month in The American Journal of Clinical Nutrition, found that walnut consumption by healthy, elderly adults had little effect on cognitive function over two years, but it had a greater effect on elderly adults who had smoked more and had a lower baseline neuropsychological test scores.

The study examined nearly 640 free-living elders in Loma Linda, California, USA, and in Barcelona, Catalonia, Spain. For two years, the test group included walnuts in their daily diet, and the control group abstained from walnuts.

Walnuts contain omega-3 fatty acids and polyphenols, which have previously been found to counteract oxidative stress and inflammation, both of which are drivers of cognitive decline.

Joan Sabaté, MD, DrPH, professor of nutrition and epidemiology at Loma Linda University School of Public Health and the study's principal investigator, said this was the largest and most well-controlled trial ever conducted on the effects of nuts on cognition.

"While this was a minor result, it could lead to better outcomes when conducted over longer periods of time," Sabaté said. "Further investigation is definitely warranted based on our findings, especially for disadvantaged populations, who may have the most to gain from incorporating walnuts and other nuts into their diet."

Sabaté and his research team at Loma Linda University were the first to discover the cholesterol-lowering effect of nut consumption -- specifically walnuts -- with lowering blood cholesterol. Findings were first published in the New England Journal of Medicine in 1993.

Subsequently, findings from Loma Linda University researchers have linked nut consumption to lower risk of cardiovascular diseases.

The Walnuts and Healthy Aging Study was funded by a grant from the California Walnut Commission, which had no input in the study design, data collection, analyses, or writing and submission of the manuscript.
