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.

FDA Approves Xaracoll (bupivacaine hydrochloride) Implant for Acute Postsurgical Pain Relief Following Open Inguinal Hernia Repair

In continuation of my update on bupivacaine 

Innocoll Holdings Limited, a specialty pharmaceutical company and portfolio business of Gurnet Point Capital, announced today that the US Food and Drug Administration (FDA) has approved Xaracoll  for acute postsurgical pain relief for up to 24 hours in adults following open inguinal hernia repair, a painful and commonly-performed surgery.1  

Xaracoll is a unique, non-injectable drug-device combination in the form of a fully bioresorbable collagen implant containing bupivacaine hydrochloride. Xaracoll is placed directly into the surgical site during surgery and, after placement, releases bupivacaine immediately and over time.1,2

“Xaracoll is an advancement in the management of postsurgical pain as it is the first and only drug-device combination product to provide local pain relief following open inguinal hernia repair in adults,” said Innocoll CEO Rich Fante. “The FDA approval is an important milestone for Innocoll and we are excited to bring Xaracoll to market later this year as an effective and well-tolerated, non-opioid treatment option for surgeons.”

The efficacy and safety of Xaracoll was evaluated in two Phase III studies of identical design in open inguinal hernia repair. The Phase III studies were performed as outpatient surgeries in adults across 39 sites (N=610, Xaracoll Arm N=404, Placebo Arm N=206) in the US. Xaracoll provided statistically significant pain relief through 24 hours versus placebo, the primary endpoint for both studies. The first secondary endpoint of total use of opioid analgesia through 24 hours was also statistically significant. Additionally, the proportion of patients who did not receive opioid rescue analgesia through 72 hours in the Xaracoll and placebo treatment groups was 36% and 22%, respectively, in Study 1, and 28% and 12%, respectively, in Study 2.  The median time to first opioid rescue analgesia in the Xaracoll and placebo treatment groups was 11 hours and 1 hour, respectively, in Study 1, and 6 hours and 1 hour, respectively in Study 2. The most common adverse reactions in clinical trials (incidence ≥2% and higher than placebo) included incision site swelling, dysgeusia, headache, tremor, blurred vision, seroma, scrotal swelling, pyrexia, oral hypoesthesia, and post procedural discharge.1,3

“In Phase III studies Xaracoll was shown to provide local pain relief in patients undergoing open inguinal hernia repair while also decreasing the amount of opioids needed,” said Wendy Niebler DO, MBA, Chief Medical Officer at Innocoll. “We look forward to sharing our Phase III data with surgeons as we introduce this new option to manage acute pain following open inguinal hernia repair in adults.”  

INDICATIONS AND USAGE

Xaracoll contains an amide local anesthetic and is indicated in adults for placement into the surgical site to produce postsurgical analgesia for up to 24 hours following open inguinal hernia repair.

FDA Approves Winlevi (clascoterone) Cream for the Treatment of Acne

Cassiopea SpA (SIX: SKIN),  announced   the United States Food and Drug Administration (FDA) approval of  Winlevi (clascoterone cream 1%) for the treatment of acne in patients 12 years and older. Notwithstanding acne being the most prevalent skin condition in the U.S. affecting up to 50 million Americans annually1, the last FDA approval of an acne drug with a new mechanism of action (MOA) occurred nearly 40 years ago.

Acne is a multifactorial skin condition, affected by four distinct pathways: excess oil (sebum) production, clogged pores (hyperkeratinization), bacteria growth (C. acnes), and inflammation2. Topical treatment options that target androgens, which largely drive sebum production and inflammation, presented a significant unmet need in the acne treatment market until now.

“The approval of Winlevi is an exciting breakthrough in acne treatment. This game-changing topical drug offers a non-antibiotic approach to people with acne, by targeting the androgen receptors directly in the skin. It fills a longstanding gap in acne therapy.” said Michael Gold, M.D., Investigator and Medical Director, Gold Skin Care Center and Tennessee Clinical Research Center. “After 40 years, it provides a much-anticipated, complementary new approach to treat acne.”

Cassiopea’s first-in-class topical androgen receptor inhibitor, Winlevi, tackles the androgen hormone component of acne in both males and females. Androgen receptor inhibitors act by limiting the effects of these hormones on increasing sebum production and inflammation3.

In pivotal clinical trials, Winlevi demonstrated treatment success and reductions in acne lesions and was well tolerated when used twice a day. The most frequently observed local skin reaction was mild erythema4,5.

Diana Harbort, CEO of Cassiopea, said: “This milestone approval marks the introduction of a new class of topical medication in Dermatology. Dermatologists have said targeting androgen hormonal activity in the skin is ‘the holy grail’ of acne treatment for both males and females. We are proud to bring this new innovation to acne patients. This approval rewards many years of hard work and positions Cassiopea as a leader in Dermatology. Now we look forward to expanding our franchise and advancing our next investigational drug candidate for androgenetic alopecia.”

Winlevi is expected to be available in the United States in early 2021. Complete prescribing information is available on www.WINLEVI.com.

About Winlevi (clascoterone cream 1%)

Winlevi (clascoterone cream 1%) is approved for the treatment of acne vulgaris in people aged 12 and older. Although Winlevi’s exact mechanism of action is unknown, laboratory studies suggest the active ingredient, clascoterone, competes with androgens, specifically dihydrotestosterone (DHT), for binding to the androgen receptors within the sebaceous gland and hair follicles6.

Cow's Milk Intake While Breastfeeding May Cut Child Food Allergies

In continuation of my update on cow milk

Children whose mothers drink more cow's milk during breastfeeding are at a lower risk for developing food allergies, according to a study recently published in Nutrients.

Mia Stråvik, from Chalmers University of Technology in Gothenburg, Sweden, and colleagues compared the dietary intake of 508 pregnant and lactating women, validated the data with biomarkers of fatty acid proportions from breast milk and erythrocytes, and related these data to physician-diagnosed allergy in the offspring at 12 months of age.

The researchers found that an increased maternal intake of cow's milk during lactation was associated with a lower prevalence of physician-diagnosed food allergy by 12 months of age. This association was confirmed with biomarkers (fatty acids: pentadecanoic acid and heptadecanoic acid) in the maternal blood and breast milk. There was a higher prevalence of atopic eczema seen at 12 months of age among mothers with a higher intake of fruit and berries during lactation.

"One hypothesis is that cow's milk contains something that activates the child's immune system and helps it to develop tolerance. This as-yet unknown cause could be found in the fat of the milk or in its protein content," a coauthor said in a statement. "But it could also be the case that the milk itself is neutral in relation to the immune system. Then it might be more simply a matter of a higher intake of milk fats leading to a relatively lower intake of polyunsaturated fats. This would help, because we believe high levels of polyunsaturated fat in a mother's diet can counteract the maturation of a child's immune system at an early age."

AHA: Mavacamten May Treat Hypertrophic Cardiomyopathy

Compared with placebo, mavacamten (Mava), a novel inhibitor of cardiac myosin, for 30 weeks leads to improvement in left ventricular (LV) hypertrophy and markers of left-sided filling pressures in patients with obstructive hypertrophic cardiomyopathy (oHCM), according to a study presented at the American Heart Association Scientific Sessions 2020, held virtually from Nov. 13 to 17.

Sheila M. Hegde, M.D., M.P.H., from Brigham and Women's Hospital in Boston, and colleagues examined the effect of Mava on focused measures of cardiac structure and function in oHCM in a double-blind, placebo-controlled phase 3 trial. Symptomatic oHCM patients were randomly assigned to either Mava or placebo for 30 weeks in a 1:1 ratio; 244 patients completed the study.

The researchers found that 30-week treatment with Mava led to significant reductions in left arterial volume index, lateral E/e', septal E/e'. and LV mass index compared with placebo. Significantly more patients treated with Mava than placebo achieved resolution of mitral valve systolic anterior motion and mitral regurgitation (80.9 versus 34.0 percent and 9.0 versus 0.0 percent, respectively).

"These findings reinforced and extended data from prior open label trials. Additional changes in measures of cardiac structure and function were also observed, including reduction in the size of the left atrium," Hedge said in a statement. "Together, these results reflect this medication's impact on the underlying pathophysiology of hypertrophic cardiomyopathy. A long-term extension trial is ongoing and will provide additional insight on the long-term impact on cardiac structure and function."

Several authors disclosed financial ties to pharmaceutical companies, including MyoKardia, which is developing mavacamten and funded the study.

FDA Approves Viltepso (viltolarsen) for the Treatment of Duchenne Muscular Dystrophy in Patients Amenable to Exon 53 Skipping Therapy

NS Pharma, Inc. announced  the U.S. Food & Drug Administration (FDA) has approved Viltepso (viltolarsen) injection for patients with Duchenne muscular dystrophy (DMD) who are amenable to exon 53 skipping therapy. Viltepso received an Accelerated Approval by the FDA based on an increase in dystrophin, a key protein for supporting muscle health. Since a lack of dystrophin is the underlying cause of DMD, increasing dystrophin as much and as early as possible is a key goal in the treatment of DMD. Viltepso is the first and only exon 53 skipping therapy to demonstrate an increase in dystrophin in children as young as four years old. The continued approval of Viltepso may be contingent on confirmation of a clinical benefit in a Phase 3 confirmatory trial.

DMD is caused by genetic mutations that prevent dystrophin production. Patients with DMD experience progressive and irreversible muscle loss with symptoms appearing as early as two years of age. Cardiac and respiratory muscle problems begin in the teenage years and lead to serious, life-threatening complications.

The Viltepso New Drug Application (NDA) submission included results from a Phase 2, two-period study in patients aged four to less than 10 years of age conducted in North America (Study 1, N=16) and a multicenter, open-label study in boys five to less than 18 years of age conducted in Japan (Study 2, N=16).

In Study 1, of those patients who received the recommended dose of 80 mg/kg/wk (N=8), 100% of patients (8/8) showed an increase in dystrophin levels after treatment with Viltepso and 88% of patients (7/8) showed dystrophin levels of 3% or greater than normal. Overall, after 20-24 weeks of treatment a mean increase in dystrophin expression to nearly 6% of normal was observed with Viltepso (80 mg/kg/wk) versus 0.6% at baseline.

The most common side effects of Viltepso included upper respiratory tract infection, injection site reaction, cough and fever.

"For decades, neurologists who treat DMD have hoped for the discovery of therapies capable of significantly improving dystrophin production, and the magnitude of dystrophin increases observed with Viltepso are impressive," said study investigator Vamshi Rao, MD, Ann & Robert H. Lurie Children's Hospital of Chicago. "The approval of Viltepso is an exciting development for DMD patients amenable to exon 53 skipping therapy and may rapidly become a foundational treatment for these patients."

Patients receiving treatment with Viltepso have the option and flexibility to receive infusions at their home or at a hospital or treatment center. Viltepso is administered by a trained healthcare professional as an 80 mg per kg of body weight 60-minute weekly intravenous infusion.

NS Pharma will provide families, physicians and healthcare professionals dedicated and individualized resources every step of the way through the NS Support program. NS Pharma will be hosting a series of webinars on the comprehensive care coordination available through NS Support. Follow us on LinkedIn and Twitter for information and registration for upcoming webinars.

"On behalf of NS Pharma and Nippon Shinyaku, I would like to express our deepest gratitude to the families and physicians who participated in our clinical trials and made today's approval possible," said Tsugio Tanaka, President, NS Pharma, Inc. "We are proud to now offer an important new treatment option to help address the significant unmet needs caused by this devastating disease."

NS Pharma continues to study the safety and efficacy of Viltepso in the confirmatory Phase 3 RACER53 trial. This study was initiated in October 2019 and is currently enrolling. The purpose of this Phase 3 trial is to confirm the clinical findings that were submitted under the Accelerated Approval pathway.

FDA Approves Evrysdi (risdiplam) for Treatment of Spinal Muscular Atrophy (SMA) in Adults and Children 2 Months and Older

Genentech, a member of the Roche Group, announced the U.S. Food and Drug Administration (FDA) approval of Evrysdi (risdiplam) for treatment of spinal muscular atrophy (SMA) in adults and children 2 months of age and older. Evrysdi showed clinically-meaningful improvements in motor function across two clinical trials in people with varying ages and levels of disease severity, including Types 1, 2, and 3 SMA. Infants achieved the ability to sit without support for at least 5 seconds, a key motor milestone not normally seen in the natural course of the disease. Evrysdi also improved survival without permanent ventilation at 12 and 23 months, compared to natural history. A liquid medicine, Evrysdi is administered daily at home by mouth or feeding tube.

“Given the majority of people with SMA in the U.S. remain untreated, we believe Evrysdi, with its favorable clinical profile and oral administration, may offer meaningful benefits for many living with this rare neurological disease,” said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. “The strength and resolve of the SMA community has continually inspired us as we developed this first-of-its-kind medicine for SMA, so today we celebrate our collective accomplishment together with them.”

Evrysdi is being studied in more than 450 people as part of a large and robust clinical trial program in SMA. The program includes infants aged 2 months to adults aged 60 with varying symptoms and motor function, such as people with scoliosis or joint contractures, and those previously treated for SMA with another medication. The approval is based on data from two clinical studies designed to represent a broad spectrum of people living with SMA: FIREFISH in symptomatic infants aged 2 to 7 months; and SUNFISH in children and adults aged 2 to 25 years. SUNFISH is the first and only placebo-controlled trial to include adults with Types 2 and 3 SMA.

In FIREFISH, 41% (7/17) of infants treated with the therapeutic dose achieved the ability to sit without support for at least 5 seconds as measured by the Bayley Scales of Infant and Toddler Development Third Edition (BSID-III). Additionally, 90% (19/21) of infants were alive without permanent ventilation at 12 months of treatment and reached 15 months of age or older. As described in the natural history of untreated infantile-onset SMA, infants would not be expected to be able to sit independently, and only 25% would be expected to survive without permanent ventilation beyond 14 months of age. In SUNFISH, children and adults treated with Evrysdi experienced a clinically-meaningful and statistical-significant improvement in motor function at 12 months (1.55 point mean difference; p=0.0156) compared to placebo (1.36 points [95% CI: 0.61, 2.11]; -0.19 points [95% CI: -1.22, 0.84], respectively), as measured by a change from baseline in the Motor Function Measure-32 (MFM-32) total score.

Evrysdi demonstrated a favorable efficacy and safety profile, with the safety profile established across the FIREFISH and SUNFISH trials. The most common adverse reactions were fever, diarrhea, and rash in later-onset SMA. In infantile-onset SMA, the most common adverse events were similar and also included upper respiratory tract infection, pneumonia, constipation, and vomiting. There were no treatment-related safety findings leading to withdrawal from either study.

“Throughout their lives, many people with SMA may lose their ability to perform critical movements, which can impact the ability to independently participate in aspects of daily life and even be life altering,” said Kenneth Hobby, president of Cure SMA. “The approval of Evrysdi is an eagerly awaited milestone for our community. We appreciate Genentech’s commitment to reflecting the full scope of the real-world SMA population in their clinical trial program and developing a treatment that can be administered at home.”

Evrysdi is designed to treat SMA by increasing production of the survival of motor neuron (SMN) protein. SMN protein is found throughout the body and is critical for maintaining healthy motor neurons and movement. Genentech leads the clinical development of Evrysdi as part of a collaboration with the SMA Foundation and PTC Therapeutics.

Evrysdi will be available in the United States within two weeks for direct delivery to patients’ homes through Accredo Health Group Inc., an Express Scripts specialty pharmacy.

Genentech is committed to helping patients access the medicines prescribed by their physician. For people with SMA, the MySMA Support program team is available to answer questions, provide product education and help families understand insurance coverage and navigate appropriate financial assistance options to start and stay on Evrysdi. Patients can call 1-833-EVRYSDI or visit http://www.Evrysdi.com or https://www.Genentech-Access.com to learn more.

FDA Approves Lampit (nifurtimox) for the Treatment of Chagas Disease in Children

Bayer announced  that  the United States Food and Drug Administration (FDA) has approved Lampit (nifurtimox) for use in pediatric patients (from birth to less than 18 years of age and weighing at least 2.5 kg) for the treatment of Chagas disease (American Trypanosomiasis) caused by Trypanosoma cruzi (T. cruzi).1 Lampit, an antiprotozoal medication will be available in a new, dividable tablet that can be split on the scored lines by hand.1-3 According to prescribing instructions, the tablet is specially formulated to disperse in water, which can aid in the dosing and administration to pediatric patients who may have difficulty swallowing whole or half tablets. 

This indication is approved under accelerated approval based on the number of treated patients who became immunoglobulin G (IgG) antibody negative or who showed an at least 20% decrease in optical density on two different IgG antibody tests against antigens of T. cruzi. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).

Chagas is an infectious tropical disease that affects an estimated 300,000 people in the U.S.4 The disease is endemic throughout much of Latin America, though it is a growing health concern in the U.S.5,6 Approval of a treatment for pediatric patients is an important milestone.

“Chagas disease can strike at any age, and early detection and treatment are important. This is especially relevant for children,” said Aleksandra Vlajnic, MD, senior vice president and head of Medical Affairs for the Americas at Bayer. “The importance of treating children is a major reason behind Bayer’s collaboration with health authorities to enhance access to Lampit as a means to provide treatment for Chagas disease.”

The FDA approval is based on results from the Chagas disease in children treated with nifurtimoxstudy, the first part of the largest Phase III program ever conducted in pediatric patients for the treatment of Chagas disease.

“In the study, Lampit showed good antiprotozoal activity in patients from 0 to 17 years old,” said Jaime Altcheh, MD, head of the Department of Parasitology and Chagas disease at the Ricardo Gutierrez Children’s Hospital in Buenos Aires, Argentina, and coordinating investigator of the Phase III trial.

The Phase III Lampit study was the first part of a prospective, randomized (to dosing regimen), double-blind evaluation of the efficacy, safety, and pharmacokinetics of nifurtimox in 330 children with Chagas disease.1 The study was conducted at 25 investigational sites in Argentina, Bolivia, and Colombia between 2016 and 2018.7 In the study, 330 pediatric patients with serologic evidence of T. cruzi infection (without Chagas disease-related cardiovascular and/or gastrointestinal symptoms) were randomly assigned in a 2:1 fashion to receive either a 60-day (n=219) or a 30-day (n=111) Lampit treatment regimen, and were followed up for one year after end of treatment.1 The results showed superiority in favor of the nifurtimox 60-day arm compared to the nifurtimox 30-day arm (not an approved dosing regimen). For additional clinical trial information, go to clinicaltrials.gov NCT02625974 and see full prescribing information. 

The study will continue with a second part (Lampit SECURE) to follow patients for an additional three years to confirm efficacy and safety.

Now that Lampit is approved for pediatric use in the U.S., Bayer is working to ensure access to the drug for all patients through retail channels. Commercially insured patients may qualify for a $0 co-pay to help with their out-of-pocket costs. For uninsured patients who cannot afford Lampit, the Bayer U.S. Patient Assistance Foundation, a charitable organization, will help eligible patients obtain the prescription medication at no cost. Restrictions apply. See Program Details for full information. Lampit is not approved in the U.S. for use in adults 18 years of age or older.

Fluvoxamine may prevent serious illness in COVID-19 patients, study suggests: Antidepressant drug repurposed for patients with coronavirus infection

In a preliminary study of COVID-19 patients with mild-to-moderate disease who were attempting to recover in their homes, researchers at Washington University School of Medicine in St. Louis have found that the drug fluvoxamine seems to prevent some of the most serious complications of the illness and make hospitalization and the need for supplemental oxygen less likely.

The study, a collaboration between the university's Department of Psychiatry and Division of Infectious Diseases, involved 152 patients infected with SARS-CoV-2, the virus that causes COVID-19. Researchers compared the outcomes of those treated with fluvoxamine to the outcomes of those given an inactive placebo. After 15 days, none of the 80 patients who had received the drug experienced serious clinical deterioration. Meanwhile, six of the 72 patients given placebo (8.3%) became seriously ill, with four requiring hospitalization.

The study is published online Nov. 12 in the Journal of the American Medical Association.

"The patients who took fluvoxamine did not develop serious breathing difficulties or require hospitalization for problems with lung function," said the paper's first author, Eric J. Lenze, MD, the Wallace and Lucille Renard Professor of Psychiatry. "Most investigational treatments for COVID-19 have been aimed at the very sickest patients, but it's also important to find therapies that prevent patients from getting sick enough to require supplemental oxygen or to have to go to the hospital. Our study suggests fluvoxamine may help fill that niche."

Fluvoxamine is used commonly to treat obsessive-compulsive disorder (OCD), social anxiety disorder and depression. It is in a class of drugs known as selective serotonin-reuptake inhibitors (SSRIs), but unlike other SSRIs, fluvoxamine interacts strongly with a protein called the sigma-1 receptor. That receptor also helps regulate the body's inflammatory response.

"There are several ways this drug might work to help COVID-19 patients, but we think it most likely may be interacting with the sigma-1 receptor to reduce the production of inflammatory molecules," said senior author Angela M Reiersen, MD, an associate professor of psychiatry. "Past research has demonstrated that fluvoxamine can reduce inflammation in animal models of sepsis, and it may be doing something similar in our patients."

Reiersen said the drug's effects on inflammation could prevent the immune system from mounting an overwhelming response, which is thought to occur in some COVID-19 patients who seem to improve after a few days of illness and then worsen. Many of those patients end up hospitalized, and some die.

In an innovative twist to research during the pandemic, the study was conducted remotely. When a symptomatic patient tested positive and enrolled in the study, research staff delivered the medication or inactive placebo to them, along with thermometers, automatic blood pressure monitors and fingertip oxygen sensors.

"Our goal is to help patients who are initially well enough to be at home and to prevent them from getting sick enough to be hospitalized," said Caline Mattar, MD, an assistant professor of medicine in the Division of Infectious Diseases. "What we've seen so far suggests that fluvoxamine may be an important tool in achieving that goal."

For two weeks, subjects took either the antidepressant drug or placebo sugar pills while having daily interactions with members of the research team -- via phone or computer. That allowed patients to report on their symptoms, oxygen levels and other vital signs. If patients suffered shortness of breath or were hospitalized for pneumonia, or their oxygen saturation levels fell below 92%, their conditions were considered to have deteriorated.

"The good news is that not a single person taking the active medication experienced deterioration," Reiersen said. "We believe this drug may be the reason, but we need to study more patients to make sure."

The researchers will begin a larger study in the next few weeks. Lenze, the director of the Healthy Mind Lab at the School of Medicine, is an expert in using mobile and internet technology to conduct clinical trials. He said that although this initial study involved patients in the St. Louis region, the next phase of the research will involve patients from throughout the country.

"We bring the study to the patients, giving them tools to monitor their health at home," Lenze said. "Our hope is that we can keep these patients healthy enough to avoid hospitalization."

This work was supported by the Taylor Family Institute for Innovative Psychiatric Research, the Bantly Foundation, the Center for Brain Research in Mood Disorders at Washington University and the COVID-19 Early Treatment Fund. Additional support from the National Center for Advancing Translational Sciences of the National Institutes of Health (NIH). Grant number UL1 TR002345.

FDA Approves Zeposia (ozanimod) for Relapsing Forms of Multiple Sclerosis

Myers Squibb Company (NYSE: BMY)  announced that the U.S. Food and Drug Administration (FDA) approved Zeposia (ozanimod) 0.92 mg for the treatment of adults with relapsing forms of multiple sclerosis (RMS), including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease.1 Zeposia, an oral medication taken once daily, is the only approved sphingosine-1-phosphate (S1P) receptor modulator that offers RMS patients an initiation with no genetic test and no label-based first-dose observation required for patients.1,4,5 An up-titration scheme should be used to reach the maintenance dosage of Zeposia, as a transient decrease in heart rate and atrioventricular conduction delays may occur.

Multiple sclerosis (MS) is a disease in which the immune system attacks the protective myelin sheath that covers the nerves, creating damaging lesions that make it harder for signals to travel between each nerve cell.6,7 This “signal breakdown” can lead to symptoms and relapses.6,8

“With the FDA approval of Zeposia, appropriate patients with relapsing forms of multiple sclerosis will have another oral treatment option with meaningful efficacy to help address the disease’s hallmark relapses and brain lesions,”9 said Samit Hirawat, M.D., chief medical officer, Bristol Myers Squibb. “Zeposia has substantial clinical potential, and we are well positioned with our heritage in transformational science to ensure this innovative compound ultimately benefits as many patients as possible.”

The approval is based on data from the largest pivotal, head-to-head RMS studies with an active comparator to date: the randomized, active-controlled Phase 3 SUNBEAM™ (safety and efficacy of Zeposia versus interferon beta-1a in relapsing multiple sclerosis) and RADIANCE™ (safety and efficacy of the selective sphingosine 1-phosphate receptor modulator Zeposia in relapsing multiple sclerosis) Part B clinical trials of more than 2,600 adults.1,2,3,10 In both trials – as compared to AVONEX® (interferon beta-1a), Zeposia delivered powerful efficacy as measured by annualized relapse rate (ARR), as well as on the number and size of brain lesions.1,2,3

• Zeposia demonstrated a relative reduction in ARR versus AVONEX of 48% through one year and 38% at two years (absolute ARR of 0.18 versus 0.35 and 0.17 versus 0.28, respectively).1,2,3
• At one year, treatment with Zeposia reduced the number of T1-weighted gadolinium-enhanced (GdE) brain lesions more than AVONEX (0.16 vs 0.43), a relative reduction of 63%, and reduced the number of new or enlarging T2 lesions (1.47 vs. 2.84), a relative reduction of 48%.1,3
• At two years, treatment with Zeposia reduced the number of T1-weighted gadolinium-enhanced (GdE) brain lesions more than AVONEX (0.18 vs 0.37), a relative reduction of 53%.1,2 Zeposia also reduced the number of new or enlarging T2 lesions vs AVONEX (1.84 vs 3.18), a relative reduction of 42%.1,2

There was no statistically significant difference in the three-month and six-month confirmed disability progression between Zeposia- and AVONEX- treated patients over two years.1

Zeposia demonstrated acceptable safety and tolerability in the Phase 3 SUNBEAM and RADIANCE Part B trials.1,2,3 Zeposia is contraindicated in patients who in the last six months experienced myocardial infarction, unstable angina, stroke, transient ischemic attack (TIA), decompensated heart failure requiring hospitalization, or Class III/IV heart failure; patients who have a presence of Mobitz type II second or third-degree atrioventricular (AV) block, sick sinus syndrome, or sino-atrial, unless the patient has a functioning pacemaker; patients with severe untreated sleep apnea; and patients taking a monoamine oxidase inhibitor.1 Zeposia is associated with the following Warnings and Precautions: increased risk of infections, bradyarrhythmia and atrioventricular conduction delays, liver injury, fetal risk, increased blood pressure, respiratory effects, macular edema, posterior reversible encephalopathy syndrome, additive immunosuppressive effects from prior immune-modulating treatments, severe increase in disability after stopping Zeposia, and immune system effects after stopping Zeposia.1 Please see Important Safety Information for additional details. The most common adverse reactions (incidence ≥4%) were upper respiratory infection, hepatic transaminase elevation, orthostatic hypotension, urinary tract infection, back pain, and hypertension.1

Before initiation of treatment with Zeposia, all patients require assessments including a recent complete blood count including lymphocyte count (within six months or after discontinuation of prior MS therapy), an ECG to determine whether preexisting conduction abnormalities are present, a recent liver function test (within six months), and consideration of current and prior medications, including vaccinations.¹ For patients with a history of uveitis or macular edema, an ophthalmic assessment is required.

Treatment for relapsing forms of multiple sclerosis is critical to address this devastating neurological disease.11 I’m excited, with the introduction of Zeposia, I will have a new oral option to offer my RMS patients that has demonstrated efficacy and safety,”1 said Bruce Cree, M.D., Ph.D., M.A.S., professor of clinical neurology, University of California San Francisco (UCSF) Weill Institute for Neurosciences and clinical research director, UCSF MS Center.

“Multiple sclerosis is an unpredictable and often disabling disease that affects nearly one million people in the United States.9,12 Ongoing treatment with disease-modifying therapy can reduce the number of disease attacks,”11 said Bruce Bebo, executive vice president of research, National Multiple Sclerosis Society. “Each person can respond differently to these medications, which is why having treatment options is so important. We are pleased that there will now be another effective treatment option for people with MS.”

As the country’s healthcare system is dealing with the unprecedented COVID-19 pandemic, Bristol Myers Squibb has made the decision to delay commercialization of Zeposia. The Company made the decision based on what’s in the best health interest of our patients, customers and employees. Bristol Myers Squibb will continue to monitor the environment and will partner with the neurology community to inform launch timing.

A Marketing Authorization Application for Zeposia for the treatment of adults with relapsing-remitting multiple sclerosis in the European Union is currently under review with the European Medicines Agency (EMA). A regulatory decision from the EMA is expected in the first half of 2020.

Kratom Seems Safe for Pain, Anxiety, Opioid Withdrawal

We know that, Mitragyna speciosa (commonly known as kratom is a tropical evergreen tree in the coffee family native to Southeast Asia. It is indigenous to Thailand, Indonesia, Malaysia, Myanmar, and Papua New Guinea, where it has been used in traditional medicines since at least the nineteenth century. Kratom has opioid properties and some stimulant-like effects.

Kratom is used for symptoms of pain, anxiety, depression, and opioid withdrawal, and serious adverse events are uncommon, according to a the results of a survey published online Feb. 3 in Drug and Alcohol Dependence.

Albert Garcia-Romeu, Ph.D., from the Johns Hopkins University School of Medicine in Baltimore, and colleagues conducted a cross-sectional online survey in 2017 involving 2,798 kratom users.

The researchers found that kratom was mainly taken orally in doses of 1 to 3 g (49 percent) and was most commonly used daily (59 percent). Kratom was used for pain, anxiety, and depression (91, 67, and 65 percent, respectively); effectiveness was highly rated. Overall, 41 percent (1,144 individuals) used kratom to stop or reduce prescription or illicit opioid use, with reports of decreased opioid withdrawal and craving in relation to use; continuous abstinence from opioids for more than one year was attributed to kratom use by 411 individuals. Adverse effects of kratom were reported by about one-third of respondents; these adverse effects were mainly rated as mild in severity and lasted ≤24 hours. Only 0.6 percent of participants sought treatment for adverse events. Two percent of participants met criteria for past-year moderate or severe kratom-related substance use disorder.

"Although our findings show kratom to be relatively safe according to these self-reports, unregulated medicinal supplements raise concerns with respect to contamination or higher doses of the active chemicals, which could increase negative side effects and harmful responses," Garcia-Romeu said in a statement.

FDA Approves Isturisa (osilodrostat) for the Treatment of Cushing’s Disease

The U.S. Food and Drug Administration today approved Isturisa (osilodrostat) oral tablets for adults with Cushing’s disease who either cannot undergo pituitary gland surgery or have undergone the surgery but still have the disease. 

Cushing’s disease is a rare disease in which the adrenal glands make too much of the cortisol hormone. Isturisa is the first FDA-approved drug to directly address this cortisol overproduction by blocking the enzyme known as 11-beta-hydroxylase and preventing cortisol synthesis.

“The FDA supports the development of safe and effective treatments for rare diseases, and this new therapy can help people with Cushing’s disease, a rare condition where excessive cortisol production puts them at risk for other medical issues,” said Mary Thanh Hai, M.D., acting director of the Office of Drug Evaluation II in the FDA’s Center for Drug Evaluation and Research. “By helping patients achieve normal cortisol levels, this medication is an important treatment option for adults with Cushing’s disease.”

Cushing’s disease is caused by a pituitary tumor that releases too much of a hormone called adrenocorticotropin, which stimulates the adrenal gland to produce an excessive amount of cortisol. The disease is most common among adults between the ages of 30 to 50, and it affects women three times more often than men. Cushing’s disease can cause significant health issues, such as high blood pressure, obesity, type 2 diabetes, blood clots in the legs and lungs, bone loss and fractures, a weakened immune system and depression. Patients may have thin arms and legs, a round red full face, increased fat around the neck, easy bruising, striae (purple stretch marks) and weak muscles.

Isturisa’s safety and effectiveness for treating Cushing’s disease among adults was evaluated in a study of 137 adult patients (about three-quarters women) with a mean age of 41 years. The majority of patients either had undergone pituitary surgery that did not cure Cushing’s disease or were not surgical candidates. In the 24-week, single-arm, open-label period, all patients received a starting dose of 2 milligrams (mg) of Isturisa twice a day that could be increased every two weeks up to 30 mg twice a day. At the end of this 24-week period, about half of patients had cortisol levels within normal limits. After this point, 71 patients who did not need further dose increases and tolerated the drug for the last 12 weeks entered an eight-week, double-blind, randomized withdrawal study where they either received Isturisa or a placebo (inactive treatment). At the end of this withdrawal period, 86% of patients receiving Isturisa maintained cortisol levels within normal limits compared to 30% of patients taking the placebo.

The most common side effects reported in the clinical trial for Isturisa were adrenal insufficiency, headache, vomiting, nausea, fatigue and edema (swelling caused by fluid retention). Hypocortisolism (low cortisol levels), QTc prolongation (a heart rhythm condition) and elevations in adrenal hormone precursors (inactive substance converted into a hormone) and androgens (hormone that regulates male characteristics) may also occur in people taking Isturisa.

Isturisa is taken by mouth twice a day, in the morning and evening as directed by a health care provider. After treatment has started, a provider may re-evaluate dosage, depending upon the patient’s response.

Isturisa received Orphan Drug Designation, which is a special status granted to a drug intended to treat a rare disease or condition.

FDA Approves Durysta (bimatoprost implant) to Lower Intraocular Pressure In Open-Angle Glaucoma or Ocular Hypertension Patients

Allergan plc (NYSE: AGN), a leading global pharmaceutical company with more than 70 years of heritage in eye care, announced the U.S. Food and Drug Administration (FDA) approval.  With this approval, Durysta becomes the first intracameral, biodegradable sustained-release implant indicated to reduce intraocular pressure (IOP) in patients with open-angle glaucoma (OAG) or ocular hypertension (OHT).

"Today's FDA approval marks a breakthrough milestone for the glaucoma community and provides a much-needed option for patients challenged with topical drops or needing alternative options," said David Nicholson, Chief Research and Development Officer, Allergan. "At Allergan, our mission is to contribute meaningful strategies that help preserve people's vision, while ensuring that therapies are mindful of the realities of administration and compliance. As a commitment to the ongoing development of this innovation, Allergan has five ongoing Phase 3 studies with Durysta to support further potential FDA label enhancement and rest of the world approvals."

The FDA approval is based on results from the two 20-month (including 8-month extended follow up) Phase 3 ARTEMIS studies evaluating 1,122 subjects on the efficacy and safety of Durysta versus twice daily topical timolol drops, an FDA accepted comparator for registrational clinical trials, in patients with OAG or OHT. In the two Phase 3 ARTEMIS studies, Durysta reduced IOP by approximately 30 percent from baseline over the 12-week primary efficacy period, meeting the predefined criteria for non-inferiority to the study comparator.

"Millions of people are living with glaucoma, one of the leading causes of vision loss; however, new treatment options are needed to help doctors and patients better manage this disease," said Felipe Medeiros , M.D., Ph.D., Distinguished Professor of Ophthalmology and Vice-Chair for Technology, Director Clinical Research Unit, Department of Ophthalmology, Duke University. "The ARTEMIS trials demonstrated that Durysta lowered IOP in patients by approximately 30 percent and demonstrated a duration of effect through the 12-week primary efficacy period. As the first FDA-approved intracameral, biodegradable sustained-release implant providing continuous drug delivery, Durysta has the potential to significantly shift the paradigm for treating glaucoma."

With the launch of Durysta, Allergan proudly expands availability of Allergan EyeCue®, a proven reimbursement service for eye care professionals to facilitate patient benefit verification, savings program enrollment for eligible patients, and prior authorization (PA) assistance for Allergan Eye Care products.

New insecticide compounds from plant used for traditional Chinese medicine

For hundreds of years, practitioners of traditional Chinese medicine have used an herb called Stemona sessilifolia as a remedy for parasitic infections, such as those caused by pinworms and lice. Now, researchers reporting in ACS' Journal of Agricultural and Food Chemistry have identified 10 compounds that might be responsible for the herb's effectiveness. But there's a twist: The insecticides are produced by symbiotic microbes that live within the plant's cells -; not by S. sessilifolia itself.

Endophytes are microorganisms that live inside plant cells but do not cause apparent disease. Instead, some endophytes help plants survive by enhancing growth, nutrient acquisition, or resistance to drought or pests. Therefore, scientists are investigating endophytes as potential sources of new medicines and agrichemicals. Xiachang Wang, Lihong Hu and colleagues wanted to screen endophytes from S. sessilifolia for insecticidal activity.

To isolate endophytes, the researchers spread fresh, cut-up pieces of S. sessilifolia on agar plates. They then collected the bacteria that grew on the plates, analyzed the DNA and identified the microbes as Streptomyces clavuligerus. Using nuclear magnetic resonance spectroscopy and mass spectrometry, the team purified 10 new compounds from the bacteria with structures similar to a class of insecticides known as pyrroles. Testing the substances on insects revealed that they were strongly toxic to aphids and moderately toxic to spider mites. A bacterial extract containing all of the compounds had greater lethal activity than any compound alone. These substances, or the bacteria that produce them, could be promising new natural pesticides, the researchers say.
