FDA Approves Fotivda (tivozanib) for the Treatment of Adult Patients with Relapsed or Refractory Advanced Renal Cell Carcinoma

In continuation of my update on Tivozanib

AVEO Oncology (Nasdaq: AVEO)   announced  the U.S. Food and Drug Administration (FDA)   approval of  Fotivda (tivozanib) for the treatment of adults with relapsed or refractory advanced renal cell carcinoma (RCC) who have received two or more prior systemic therapies. Fotivda is an oral, next-generation vascular endothelial growth factor (VEGF) tyrosine kinase inhibitor (TKI).

“Today’s approval of Fotivda provides a new tool for treating patients with kidney cancer who have relapsed or become refractory to two or more prior systemic therapies,” said Brian Rini, MD, Chief of Clinical Trials at Vanderbilt Ingram Cancer Center and principal investigator of the TIVO-3 trial. “With advances in RCC treatment, patients are living longer, increasing the need for proven, well tolerated treatment options in the relapsed or refractory setting. The TIVO-3 study is the first positive Phase 3 study in RCC patients who received two or more prior systemic therapies, and also the first Phase 3 RCC study to include a predefined population of patients who have received prior immunotherapy, the current standard of care in earlier-line treatment. With this approval, I believe Fotivda represents an attractive intervention, and expect it to play a meaningful role in the evolving RCC treatment landscape.”

“We believe in Fotivda’s potential to provide a differentiated treatment option for the growing number of individuals in the U.S. with relapsed or refractory RCC, and today marks the culmination of many years of hard work and determination of many individuals to bring this therapy to patients,” said Michael Bailey, president and chief executive officer of AVEO. “With today’s approval, AVEO begins its journey as a commercial-stage company, a noteworthy accomplishment in our industry. On behalf of the entire AVEO team, I would like to thank all the patients, their families, and caregivers whose tireless efforts made this day possible.”

“Relapsed or refractory RCC is a devastating disease for which patient outcomes can be limited due to the tradeoff between tolerability and efficacy,” said Dena Battle, president of KCCure. “The FDA approval of Fotivda represents an exciting, meaningful advancement by providing a new treatment option for this patient population.”

AVEO plans to make Fotivda available to patients in the U.S. by March 31, 2021.

The approval of Fotivda is based on AVEO’s pivotal Phase 3 study, TIVO-3, comparing Fotivda to sorafenib in relapsed or refractory advanced RCC following two or more prior systemic therapies. The application is also supported by three additional trials in RCC and includes safety data from over 1,000 clinical trial subjects.

Patients (n=350) enrolled in the TIVO-3 study were randomized 1:1 to receive either Fotivda or sorafenib. The main efficacy outcome measure was progression-free survival (PFS), assessed by a blinded independent radiology review committee. Other efficacy endpoints were overall survival (OS) and objective response rate (ORR).

Median PFS was 5.6 months (95% CI: 4.8, 7.3) in the Fotivda arm (n=175) compared with 3.9 months (95% CI: 3.7, 5.6) for those treated with sorafenib (HR 0.73; 95% CI: 0.56, 0.95; p=0.016). Median OS was 16.4 (95% CI: 13.4, 21.9) and 19.2 months (95% CI: 14.9, 24.2), for the Fotivda and sorafenib arms, respectively (HR 0.97; 95% CI: 0.75, 1.24). The ORR was 18% (95% CI: 12%, 24%) for the Fotivda arm and 8% (95% CI: 4%, 13%) for the sorafenib arm.

The most common (≥20%) adverse reactions were fatigue, hypertension, diarrhea, decreased appetite, nausea, dysphonia, hypothyroidism, cough, and stomatitis. The most common grade 3 or 4 laboratory abnormalities (≥5%) were decreased sodium, increased lipase, and decreased phosphate.

The recommended tivozanib dose is 1.34 mg once daily with or without food for 21 days every 28 days on treatment followed by 7 days off treatment (28 day cycle) until disease progression or unacceptable toxicity.

FDA Approves Kimyrsa (oritavancin) for the Treatment of Adult Patients with Acute Bacterial Skin and Skin Structure Infections (ABSSSI)

Melinta Therapeutics, LLC (Melinta), a commercial-stage company focused on the development and commercialization of novel antibiotics, today announced that the U.S. Food and Drug Administration (FDA) has approved Kimyrsa (oritavancin)  for the treatment of adult patients with acute bacterial skin and skin structure infections (ABSSSI) caused by susceptible isolates of designated Gram-positive microorganisms, including methicillin-resistant Staphylococcus aureus (MRSA). Kimyrsa is a lipoglycopeptide antibiotic that delivers a complete course of therapy for ABSSSI in a single, one hour 1,200 mg infusion.

“The approval of Kimyrsa demonstrates Melinta’s commitment to provide innovative therapies to patients with acute and life-threatening illnesses,” said Christine Ann Miller, President and Chief Executive Officer of Melinta. “We have responded to the requests of the medical community to provide an oritavancin product with a shorter infusion time.  We believe that with the approval of Kimyrsa and product availability this summer, physicians and patients will now have a compelling new one-dose alternative to the current standard of multi-dose regimens for ABSSSI.”

ABSSSI affect approximately 14 million patients in the U.S. each year, are responsible for over 3 million visits to the Emergency Room annually and represent the 8th most common cause of Emergency Department hospital admissions1,2. ABSSSI cost U.S. hospitals $4 billion each year, with a 4.1-day average length of stay for hospitalized ABSSSI patients.2

“Kimyrsa is an important new treatment option that will provide clinicians with additional flexibility to treat ABSSSI patients in multiple care settings, without the need for hospitalization,” said Andrew Dold, D.O., member of a private infectious disease practice covering the Greater Atlanta Region. “Single-dose, long-acting antibiotics, such as Kimyrsa, may be especially beneficial for patients who lack the support or resources to adhere to multiple intravenous administrations.”

The efficacy and safety of Kimyrsa were established in the SOLO clinical trials with another oritavancin product, Orbactiv. The SOLO trials were randomized, double-blind, multicenter studies that evaluated a single 1,200 mg IV dose of oritavancin against twice-daily vancomycin for the treatment of ABSSSI in 1,987 adult patients and assessed one of the largest subsets of documented MRSA infection (405 patients). These trials demonstrated that 1,200 mg one-dose IV oritavancin infusion was as effective as 7-to-10 days of twice-daily vancomycin (1 g or 15 mg/kg) for the primary and secondary endpoints.  Kimyrsa approval is based on the results of an open-label, multi-center, pharmacokinetics study, which compared Kimyrsa administered over 1 hour (N=50) to Orbactiv administered over 3 hours (N=52) for the treatment of adult patients with ABSSSI.

Michael Waters, M.D. and lead investigator in the PK clinical trial stated, “Kimyrsa was shown to be comparable to Orbactiv with a favorable safety profile.  I’m pleased that these outcomes support the approval of Kimyrsa to provide oritavancin with a shorter infusion time and lower infusion volume.  With these features, Kimyrsa can further enhance the treatment experience for the patient and efficiency of administration in clinical practice.”

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.

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."

Newly discovered antibiotics kill bacteria differently

Antibiotic resistance is a growing public health problem across the globe, with many diseases becoming harder to treat. Now, a newly discovered antibiotic group shows promise in the fight against superbugs as it has a unique way of killing bacteria.

A team of scientists at McMaster University has found a new group of antibiotics that can fight infections in a new and unique way. These antibiotics fight infections in a way researchers have never seen before, according to the findings of the study described in the journal Nature.

'Holy grail' of antibiotics

The newly found group of antibiotics, consisting of corbomycin and complestatin, can kill bacteria by blocking the function of the bacterial cell wall. These drugs come from a family of antibiotics known as glycopeptides, which are produced by soil bacteria.

The two antibiotics attack peptidoglycan, the main component of the bacterial cell wall that is vital to the growth and survival of almost all bacteria. They inhibit the action of autolysins, which are important for cell division and growth.

Other antibiotics, such as penicillin, work by preventing the bacteria from building its wall, which is the source of its strength. In killing the bacteria, removing its wall will make it vulnerable and easier to kill.

These new antibiotics work by doing the opposite. Instead of preventing building the wall, it halts the wall ll from being broken down. As a result, blocking the breakdown of the wall would make it impossible for them to divide and expand – just like being trapped in prison.

Unique bacteria killer

The two new antibiotics are known as glycopeptides. The team studied the genes of the group to see if they lack resistance mechanisms. The team believes that if the genes that made these drugs different, perhaps the way they kill will also be different.

In collaboration with scientists from the Université de Montréal, including Yves Brun, they found that the drugs act on the bacterial cell wall to prevent it from dividing and proliferating.  

"Knowing the detailed structure at the atomic level of this connection between the surface layer and the surface of the cell offers enormous potential to then develop molecules that can target this attachment and make the cell more sensitive to antibacterials," Yves Brun, study co-author, said.

"Combined with the discovery of the new mode of action of two antibiotics, this development opens up prospects for weakening the action of bacteria and making them more vulnerable," he added.

The researchers believe the group of drugs is a promising clinical candidate in the hopes of stemming bacteria from becoming resistant to antibiotics.

Fight against antibiotic resistance

Antibiotic resistance is one of the greatest threats to global health, according to the World Health Organization (WHO). Though it happens naturally, the misuse of antibiotics is hastening the process, making it easy to treat infections in the past harder to curb now.

Further, antibiotic resistance increase hospital stays and medical costs. For instance, diseases in the past that were responsive to certain antibiotics may become resistant and difficult to stem, such as tuberculosis, pneumonia, gonorrhea, and other infections. Now, as the diseases become stronger and more resilient, outbreaks may become inevitable, unless new drugs are discovered.

In the United States alone, at least 2.8 million people become infected with antibiotic-resistant bacteria each year, while more than 35,000 people die.

Newly discovered antibiotics kill bacteria differently

Novel drug combination discovered to induce high rates of human beta cell proliferation

Harmine

Researchers at the Icahn School of Medicine at Mount Sinai have discovered a novel combination of two classes of drugs that, together, cause the highest rate of proliferation ever observed in adult human beta cells- the cells in the pancreas that produce insulin- without harming most other cells in the body. The result is an important step toward a diabetes treatment that restores the body's ability to produce insulin.

The finding involved one type of drug that is known to cause beta cells to proliferate and another that is already in widespread use in people with diabetes. Together, they caused the cells to proliferate at a rate of 5 to 6 percent per day. The study was published today in Science Translational Medicine online.

We are very excited about this new drug combination because for the first time ever, we are able to see rates of human beta cell replication that are sufficient to replenish beta cell mass in humans with diabetes."

Andrew Stewart, MD, Director of the Mount Sinai Diabetes, Obesity, and Metabolism Institute and lead author of the study

Diabetes occurs when there are not enough beta cells in the pancreas, or when those beta cells secrete too little insulin, the hormone required to keep blood sugar levels in the normal range. Approximately 30 million people in the United States have diabetes and nearly 50 to 80 million more are living with prediabetes (also called "metabolic syndrome"). Diabetes can lead to major medical complications: heart attack, stroke, kidney failure, blindness, and limb amputation.

In type 1 diabetes, the immune system mistakenly attacks and destroys beta cells. A deficiency of functioning beta cells is also an important contributor to type 2 diabetes, the most common type of diabetes. Thus, developing drugs that can increase the number of healthy beta cells is a major priority in diabetes research.

According to Dr. Stewart, none of the diabetes drugs currently on the market can induce beta cell regeneration in people with diabetes. In parallel with the Mount Sinai work, other researchers are studying pancreatic transplantation, beta cell transplantation, and stem cell replacement of beta cells for people with diabetes, but none of these approaches is in widespread use.

"This is a very exciting discovery in the field of diabetes and is a key next step in drug development for this disease," said Dennis S. Charney, MD, Anne and Joel Ehrenkranz Dean, Icahn School of Medicine at Mount Sinai. "This important work truly holds promise for so many people."

In 2015, Dr. Stewart and his team published a paper in Nature Medicine that showed that harmine, a drug that inhibits the enzyme dual specificity tyrosine-regulated kinase 1A (DYRK1A), induced multiplication of adult human beta cells. In that study, his team also discovered that harmine treatment led to normal control of blood sugar and proliferation in human beta cells in diabetic mice whose beta cells had been replaced with small numbers of transplanted human beta cells. While this was a major advance, the proliferation rate was lower than needed to rapidly expand beta cells in people with diabetes.

This current paper builds upon a study that Dr. Stewart and his team published in Cell Metabolism in December 2018 where they discovered that DYRK1A inhibitors combined with another drug that inhibits transforming growth factor beta superfamily members (TGFβSF), also known as a family of proteins with various biological processes such as growth, development, tissue homeostasis and immune system, could cause beta cells to proliferate at a rate of 5 to 8 percent per day. However, according to Dr. Stewart, TGFβSF's would likely have side effects on other organs in the body that would prevent clinical use.

The next challenge was developing ways to target regenerative drugs to the beta cells while avoiding other cells and organs in the body where they may elicit adverse effects.

In the study published today, titled "GLP-1 receptor agonists synergize with DYRK1A inhibitors to potentiate functional human beta cell regeneration," Dr. Stewart and his team combined DYRK1A inhibitors like harmine with a class of beta cell-targeting drugs, also known as GLP1R agonists, which are already in widespread use in people with type 2 diabetes. They showed-;in beta cells from normal people and people with type 2 diabetes, both in the tissue culture dishes and in human beta cells transplanted into mice-;that combining harmine (or any other DYRK1A inhibitor) with any of the many GLP1R agonist drugs currently on the market for diabetes yields high rates of human beta cell replication, and does so in a way that is highly selective for the beta cell.

The project arose from the PhD thesis of an Icahn School of Medicine graduate student, Courtney Ackeifi, now a postdoctoral fellow in Dr. Stewart's lab and first author of the paper, who explored a broad spectrum of potential drug partners that could enhance the beta cell regenerative efficacy and selectivity of harmine.

Said Dr. Ackeifi of the discovery, "The beauty here is that the combination of DYRK1A inhibitors with GLP1R agonists achieves the highest rate of human beta cell replication possible, and does so in a highly specific way. This is an important advance in the field of diabetes because we may have found a way to convert a widely used class of diabetes drugs into a potent human beta cell regenerative treatment for all forms of diabetes."

"We know that a critical pathway to drive a cure for type 1 diabetes includes transplanting insulin-producing beta cells into people or enticing their existing beta cells to start multiplying," explains Francis Martin, PhD, JDRF Director of Research. "It is exciting to learn from the work of Dr. Stewart and his team that GLP1R agonists could increase the effect of the recently discovered agents that promote multiplication. Using GLP1R offers a means to boost the effect while also improving the safety of this type of drug."

The next goals of the project are to perform long-term studies in animals transplanted with human beta cells, and to determine if any cells or organs in the body other than beta cells are affected by the new drug combination.

Oligosaccharide 2'FL in breast milk enhances cognitive development in babies

Maternal factors, such as breast milk, have been shown to affect a baby's development, and previous animal studies have determined that a carbohydrate, the oligosaccharide 2'FL found in maternal milk, positively influences neurodevelopment. Now, in the first study done in humans, investigators at Children's Hospital Los Angeles in collaboration with the University of California, San Diego, have shown that 2'FL found in breast milk enhances cognitive development. Findings will be published in PLOS ONE on Feb 12.

In this cohort study of 50 mothers and their babies, investigators analyzed breast milk composition and frequency of feeding at 1 and 6 months of age. Cognitive development was measured at 24 months using the Bayley-III scale, a standardized test of infant and toddler development. The study showed that the amount of 2'FL in breast milk in the first month of feeding was related to significantly higher cognitive development scores in babies by 2 years of age. The amount of 2'FL in breast milk at 6 months of feeding was not related to cognitive outcomes, indicating that early exposure may be more beneficial.

Many studies have reported a positive effect of breastfeeding on cognitive development. "We wanted to specifically identify what was causing this effect," said Michael Goran, PhD, Director of the Diabetes and Obesity Program at The Saban Research Institute of Children's Hospital Los Angeles and senior author on the study.

Through our high-throughput analytical platform we can quantify oligosaccharides like 2'FL and many others in hundreds of breast milk samples in a short period of time. This technology allows us to associate differences in milk composition with specific infant outcomes like cognitive development, validating existing data from preclinical models or generating entirely new hypotheses."

Lars Bode, PhD, study collaborator and co-author, Professor of Pediatrics and Director of the Mother-Milk-Infant Center of Research Excellence at the University of California, San Diego

Using a statistical technique called mediation analysis, the investigators were able to independently evaluate the effects of breastfeeding in general, and the effects of the oligosaccharide 2'FL.

"This enhanced cognitive development in the first 2 years of life raises the question of possible long term impact on a child¬-in school and beyond," said Paige Berger, PhD, RD, a postdoctoral research associate at CHLA and the first author of the study.

These observations allowed the team to conclude that the increased neurodevelopment provided by breastfeeding was due primarily to mothers who were producing more 2'FL for the baby to consume.

"We know that there are many different compounds in breast milk and the composition is dynamic - it changes over time and is highly variable between mothers," Dr. Goran said. "In addition to identifying the impact of oligosaccharide 2'FL, we also wanted to determine the timing of when it is most critical to a child's development."

While the investigators observed neuroenhancement explained by higher 2'FL during the first month of a baby's life, this effect was not observed when looking at 2'FL content of breast milk at the six-month time-point. Being able to identify factors critical to early neurodevelopment offers the possibility for supplementing women's breast milk in individuals who produce lower quantities of this important substance.

"For some women, breastfeeding is a challenge. For those that are not able to breastfeed or can only do so short-term, 2'FL could potentially be offered as an add-on to the nutrition their baby is receiving to better support cognitive development," said Dr. Berger.

Common drug could mitigate risk of 'a broken heart' during bereavement

In continuation of my update on aspirin

The increased risk of heart attack or "a broken heart" in early bereavement could be reduced by using common medication in a novel way, according to a world-first study led by the University of Sydney and funded by Heart Research Australia.

Lead Investigator Professor Geoffrey Tofler said while most people gradually adjust to the loss of a loved one, there is an increase in heart attack and death among bereaved people, particularly those grieving a spouse or child.

"The increased risk of heart attack can last up to six months. It is highest in the first days following bereavement and remains at four times the risk between seven days to one month after the loss."

The study, published in the American Heart Journal, is the first randomized controlled clinical trial to show it is possible to reduce several cardiac risk factors during this time, without adversely affecting the grieving process.

"Bereavement following the death of a loved one is one of the most stressful experiences to which almost every human is exposed," said Professor Tofler, Professor of Preventative Cardiology at the University of Sydney's Faculty of Medicine and Health, and Senior Staff Cardiologist at Royal North Shore Hospital.

"Our study is the first clinical trial to examine how the cardiac risk factors could be mitigated during early bereavement."

About the study

The research team from the University of Sydney, Royal North Shore Hospital and the Kolling Institute enrolled 85 spouses or parents in the study within two weeks of losing their family member.

Forty-two participants received low daily doses of a beta blocker and aspirin for six weeks, while 43 were given placebos. Heart rate and blood pressure were carefully monitored, and blood tests assessed blood clotting changes.

The main finding was that the active medication, used in a low dose once a day, successfully reduced spikes in blood pressure and heart rate, as well as demonstrating some positive change in blood clotting tendency."

Professor Geoffrey Tofler, lead investigator

The investigators also carefully monitored the grief reaction of participants.

"We were reassured that the medication had no adverse effect on the psychological responses, and indeed lessened symptoms of anxiety and depression," said Professor Tofler.

"Encouragingly, and to our surprise, reduced levels of anxiety and blood pressure persisted even after stopping the six weeks of daily beta blocker and aspirin."

Co-investigator Associate Professor Tom Buckley said the study builds on the team's novel work in this area with their earlier studies among the first to identify the physiological correlates of bereavement.

"While beta blockers and aspirin have been commonly used long term to reduce cardiovascular risk, they have not previously been used in this way as a short-term preventative therapy during bereavement," said

Associate Professor Buckley of the University of Sydney Susan Wakil School of Nursing and Midwifery.

Implications and next steps

The authors acknowledge that larger long-term studies are needed to identify who would benefit most however the findings provide encouragement for health care professionals to consider this preventative strategy among individuals that they consider to be at high risk associated with early bereavement.

"Our finding on the potentially protective benefit of this treatment is also a good reminder for clinicians to consider the well-being of the bereaved," said Associate Professor Buckley.

"Future studies are needed to assess if these medications could be used for other short periods of severe emotional stress such as after natural disasters or mass bereavement where currently there are no guidelines to inform clinicians."

Co-investigator Dr. Holly Prigerson, Co-Director of the Center for Research on End-of-Life Care at Weill Cornell Medicine in New York, said:

This is an important study because it shows ways to improve the physical and mental health of at-risk bereaved people. It is a preventive intervention that is potentially practice-changing, using inexpensive, commonly available medicines."

People experiencing cardiac symptoms should discuss their condition with a health care professional before taking medication as incorrect use could be harmful.
