Tue, 01/07/2025 - 11:36

TOPLINE:

The newer biologics — interleukin (IL)–17, IL-12/23, and IL-23 inhibitors — demonstrate comparable cardiovascular safety profiles to tumor necrosis factor (TNF) inhibitors in biologic-naive patients with psoriasis or psoriatic arthritis (PsA).

METHODOLOGY:

  • In a retrospective cohort study, researchers conducted an emulated target trial analysis using data of 32,098 biologic-naive patients with psoriasis or PsA who were treated with one of the newer biologics (infliximab, adalimumab, etanercept, certolizumab pegol, secukinumab, ixekizumab, brodalumab, ustekinumab, risankizumab, guselkumab, and tildrakizumab) from the TriNetX Research Network between 2014 and 2022.
  • Patients received TNF inhibitors (n = 20,314), IL-17 inhibitors (n = 5073), IL-12/23 inhibitors (n = 3573), or IL-23 inhibitors (n = 3138).
  • A propensity-matched analysis compared each class of newer biologics with TNF inhibitors, adjusting for demographics, comorbidities, and medication use.
  • The primary outcomes were major adverse cardiovascular events (MACE; myocardial infarction and stroke) or venous thromboembolic events (VTE).

TAKEAWAY:

  • Compared with patients who received TNF inhibitors, the risk for MACE was not significantly different between patients who received IL-17 inhibitors (incidence rate ratio [IRR], 1.14; 95% CI, 0.86-1.52), IL-12/23 inhibitors (IRR, 1.24; 95% CI, 0.84-1.78), or IL-23 inhibitors (IRR, 0.93; 95% CI, 0.61-1.38)
  • The VTE risk was also not significantly different between patients who received IL-17 inhibitors (IRR, 1.12; 95% CI, 0.63-2.08), IL-12/23 inhibitors (IRR, 1.51; 95% CI, 0.73-3.19), or IL-23 inhibitors (IRR, 1.42; 95% CI, 0.64-3.25) compared with those who received TNF inhibitors.
  • Subgroup analyses for psoriasis or psoriatic arthritis alone confirmed consistent findings.
  • Patients with preexisting hyperlipidemia and diabetes mellitus showed lower risks for MACE and VTE with newer biologics compared with TNF inhibitors. 

IN PRACTICE:

“No significant MACE and VTE risk differences were detected in patients with psoriasis or PsA between those receiving IL-17, IL-12/23, and IL-23 inhibitors and those with TNF inhibitors,” the authors concluded. These findings, they added “can be considered by physicians and patients when making treatment decisions” and also provide “evidence for future pharmacovigilance studies.”

SOURCE:

The study was led by Tai-Li Chen, MD, of the Department of Dermatology, Taipei Veterans General Hospital in Taipei, Taiwan. It was published online on December 27, 2024, in the Journal of the American Academy of Dermatology.

LIMITATIONS:

Study limitations included potential residual confounding factors, lack of information on disease severity, and inclusion of predominantly White individuals.

DISCLOSURES:

The study received support from Taipei Veterans General Hospital and Ministry of Science and Technology, Taiwan. The authors reported no conflicts of interest.

Upfront Therapy for ITP in Children: New Drug a Game-Changer?

Article Type
Changed
Wed, 12/18/2024 - 06:40

Children with newly diagnosed immune thrombocytopenia (ITP) treated with eltrombopag as a frontline therapy show significantly improved platelet responses and other outcomes compared with the standard of care.

“This is the first time in 30 years that a new drug is being tested for newly diagnosed pediatric ITP,” said the study’s lead author, Kristin A. Shimano, MD, professor of pediatrics at the Benioff Children’s Hospital, University of California San Francisco, in a press statement for the study, presented at the American Society of Hematology (ASH) 2024 Annual Meeting earlier this month.

“We really think that this has the potential to transform the approach to the management of ITP in the newly diagnosed phase with the use of a therapy that can provide sustained hemostatic platelet counts to bridge the time that patients are at risk of bleeding events with the goal to wean off the medication for patients who have a natural resolution of their disease,” Shimano said in her talk.

While children with ITP, a rare autoimmune blood disorder, very often improve without the need for any treatment, some do require intervention, and the condition can become chronic. First-line therapies for those patients commonly include corticosteroids, intravenous immunoglobulin (IVIg), and anti-D globulin; however, side effects can be undesirable, and with their efficacy often temporary, patients can require monitoring and juggling of treatments.

Eltrombopag, an oral, daily thrombopoietin receptor agonist, was approved by the US Food and Drug Administration for children and adults with chronic ITP in 2015; however, research has been lacking on the benefits of the therapy for newly diagnosed pediatric patients.

To investigate the drug’s efficacy at that stage, Shimano and colleagues with the ITP Consortium of North America launched the prospective, open-label Pediatric ITP Newly diagnosed pts Epag vs Standard therapy (PINES) trial, enrolling 118 patients at 23 institutions between May 2019 and January 2024.

All enrollees had been diagnosed with ITP within 3 months and had been determined by their treating hematologist to require pharmacologic treatment.

Of the patients, about 40% were untreated, and 60% had been treated with at least one medication prior to the trial but did not have a lasting response.

The patients were stratified by age and prior treatment and randomized 2:1 to receive either eltrombopag (n = 78) or the investigator’s choice of one of three standard first-line therapies, including prednisone, IVIg, or anti-D globulin at specified doses (n = 40). Overall, 29 in the standard-of-care arm received prednisone and 11 received IVIg. The patients had a median age of 8 years.

For the study’s primary endpoint, patients in the eltrombopag group had a significantly greater sustained response at 12 weeks, defined as having at least three of four platelet counts > 50 × 109/L during weeks 6-12 without the need for rescue treatment, with a rate of 63% vs 35% in the standard-of-care group (P = .0054).

There were no significant differences between the two groups in terms of the proportion of patients with a high bleeding score at weeks 1-4 and week 12.

However, those in the eltrombopag arm had a significantly lower rate of receiving rescue therapy (18% vs 38% with the standard of care; P = .02).

Both groups showed clinically meaningful improvements from baseline in terms of health-related quality of life, as assessed by parent proxy-reported KIT overall scores.

Twenty adverse events that were grade 3 or higher, including six serious adverse events, occurred in each of the study’s arms, with the most common events including headache and epistaxis.

Treatment-related serious adverse events occurred among six patients in the eltrombopag group and one in the control group, but importantly, no thromboembolic events were reported.

One intracranial hemorrhage occurred in the eltrombopag arm.

With eltrombopag having a slower effect than some other treatments, Shimano cautioned that the therapy is not recommended for patients with severe bleeding.

“Patients with grade 4 or 5 bleeding at the time of screening were specifically excluded from the study, so for patients who have very severe bleeding who need to get their platelets up very quickly, this would not be the ideal therapy for them,” she noted.

On the basis of results, the trial was recommended to close early due to efficacy; however, the participants are being followed for a total of 12 months to determine the durability of the responses, including in terms of bleeding events, quality of life, or the development of chronic ITP.

“We have shown that in pediatric patients with newly diagnosed ITP requiring pharmacologic treatment, eltrombopag resulted in a significant, clinically relevant higher rate of a durable platelet response in the absence of rescue treatment as compared with standard first-line therapies,” Shimano said.

“Eltrombopag could certainly be added to the medication choices hematologists consider as they are making treatment decisions with families, and it is an option that could potentially raise platelets for a more sustained period in children with ITP in the newly diagnosed period, which is one of the most difficult times for patients with regard to the impact of the disease on bleeding symptoms and quality of life,” she added.

Commenting on the study, James B. Bussel, MD, emeritus professor of pediatrics, medicine and obstetrics and gynecology at Weill Cornell Medicine in New York City, commented that “generally, a short-term increase in platelets is the biggest challenge, which is getting the patient to the point of not requiring future treatment to get better.”

“If more children can be shown to be going into remission earlier, that would be great,” he said.

While eltrombopag is known to be effective in chronic ITP, a key caveat of its use in newly diagnosed patients is the question of whether patients will get better on their own and feasibly be able to be spared the cost and burden of treatment in the first place.

However, identifying which patients will fit that profile isn’t always easy.

“Exactly which child needs treatment can be hard to determine, and there is some debate about that,” Bussel noted.

“The theoretic standard is that the platelet count doesn’t matter — only whether the patient is bleeding a lot, and then there is debate over treatment based on bleeding scores,” he said.

Quality-of-life issues, such as patients’ ability to take part in activities, are also a key consideration.

“It would be great if eltrombopag can support children who really need it and provide clear unequivocal benefit beyond just increasing the platelet count, but also leading to better quality of life,” Bussel said.

The new findings are “a very encouraging start, but I’d really like to see what the story is at 1 year.”

The study was funded by Novartis, maker of eltrombopag, and sponsored by the ITP Consortium of North America. Shimano disclosed ties with Sanofi, Sobi, Daiichi Sankyo, Novartis, and Pfizer. Bussel reported a relationship with Novartis that ended more than 2 years ago.

Do GLP-1s Lower VTE Risk in People With Type 2 Diabetes?

Glucagon-like peptide 1 (GLP-1) receptor agonists led to a significant reduction in the risk for venous thromboembolism (VTE) among individuals with type 2 diabetes, compared with dipeptidyl peptidase 4 (DPP-4) inhibitors, a recent analysis indicated.

Overall, GLP-1 agonist use was associated with a 20% reduction in VTE, compared with DPP-4 inhibitor use, in those with type 2 diabetes, and this benefit held regardless of people’s obesity status, said study investigator Cho-Han Chiang, MD, a medical resident at Mount Auburn Hospital, Cambridge, Massachusetts, who presented the findings at the American Society of Hematology (ASH) 2024 Annual Meeting.

The incidence of VTE has increased by 20% over the past 10 years, and obesity is a risk factor for VTE, Chiang explained. A growing body of evidence demonstrated that GLP-1s provide a variety of cardiovascular benefits in people with type 2 diabetes, but data on VTE benefits remain more limited.

In the retrospective study, the researchers combed electronic health records from the TriNetX global database, which includes more than 250 million patients, and identified adults with type 2 diabetes who were taking a GLP-1 agonist or a DPP-4 inhibitor.

After excluding anyone with prior VTE or atrial fibrillation as well as those treated with both drugs or with oral anticoagulants, patients on GLP-1s were matched with those on DPP-4 inhibitors based on predetermined variables, including age, sex, race, body mass index (BMI), hemoglobin A1c, use of other antidiabetic agents, and underlying comorbidities. VTE was a composite of pulmonary embolism and deep vein thrombosis.

The researchers also performed a subgroup analysis that stratified patients by obesity status, defined as a BMI ≥ 30.

Within 1 year of GLP-1 or DPP-4 prescription, VTE occurred at a rate of 6.5 cases/1000 person-years in the GLP-1 group vs 7.9 cases/1000 person years in the DPP-4 inhibitor group (hazard ratio [HR], 0.80; P < .001).

The 20% risk reduction in VTE held across various subgroups of BMI, including among those with obesity, Chiang reported.

Among patients with the highest BMI (≥ 40), VTE occurred at a rate of 7.2 cases/1000 person years in the GLP-1 group vs 9.6 cases/1000 person years in the DPP-4 inhibitor group (HR, 0.74). Among patients with the next highest BMI (30-34.9), VTE occurred at a rate of 4.8 cases/1000 person years in the GLP-1 group vs 7.9 cases/1000 person years in the DPP-4 inhibitor group (HR, 0.60). Among those with the lowest BMI (18.5-24.9), VTE occurred significantly less frequently among those in the GLP-1 group — 4.7 cases/1000 person years vs 7.4 cases/1000 person years in the DPP-4 inhibitor group (HR, 0.61).

The lower risk for VTE associated with GLP-1s also held across the individual components of the composite VTE. Pulmonary embolism occurred at a rate of 3.1 cases/1000 person years in the GLP-1 group vs 3.9 cases/1000 person years in the DPP-4 inhibitor group (HR, 0.78), and deep vein thrombosis occurred in 4.2 cases/1000 person years in the GLP-1 group vs 5.0 cases/1000 person years in the DPP-4 inhibitor group (HR, 0.82).

Interestingly, the GLP-1 and DPP-4 curves started diverging within the first 30 days of the index prescription date, said Chiang.

Session moderator Ghadeer Dawwas, PhD, said in an interview that patients with type 2 diabetes are increasingly using GLP-1 agonists because of the cardiovascular benefits associated with the agents, which include lower risks for stroke and heart failure, but the antithrombotic benefits are still debated.

“The current study indicates that GLP-1 agonists may help lower the risk of VTE in patients with type 2 diabetes, irrespective of their baseline body weight,” said Dawwas, a pharmacoepidemiologist and assistant professor of medicine at Vanderbilt University Medical Center in Nashville, Tennessee. “However, given the current landscape of evidence and the existence of conflicting data on VTE risk, clinicians should proceed with caution and await further studies to validate these findings before making clinical decisions.”

This study was funded by the National Blood Clot Alliance and Conquer Cancer Foundation. Chiang and Dawwas had no disclosures.

Rilzabrutinib Shines in Phase 3 Trial of Tough-to-Treat Immune Thrombocytopenia

Article Type
Changed
Wed, 12/11/2024 - 12:17

Phase 3 data support rilzabrutinib as a potential first-in-class oral Bruton tyrosine kinase (BTK) inhibitor for patients with previously treated immune thrombocytopenia (ITP). 

In the LUNA 3 trial, treatment with rilzabrutinib (Sanofi) led to rapid and durable platelet responses, reduced bleeding and need for rescue therapy, and improved health-related quality of life in patients with persistent or chronic immune thrombocytopenia. 

Notably, rilzabrutinib also “significantly improved fatigue, even among patients who did not have a significant platelet count rise,” said David J. Kuter, MD, DPhil, director of clinical hematology, Massachusetts General Hospital, Boston, who reported the findings during a press briefing at the American Society of Hematology (ASH) 2024 Annual Meeting.

Briefing moderator Charles Abrams, MD, University of Pennsylvania, Philadelphia, noted that LUNA 3 enrolled a “remarkably tough group of patients, really the hardest of the hard” and showed that rilzabrutinib was “well-tolerated and caused an increase in platelet counts.”

The study, Abrams added, demonstrates “significant progress” in treatment of a disease that has historically been viewed as “benign,” which is “good for our patients.”

Immune thrombocytopenia is a relatively rare autoimmune disease that affects 10 to 23 patients per 100,000 in the United States. For those with the condition, the body’s immune system attacks platelets, causing platelet counts to drop below 100,000/μL of blood. The disease leads to increased bleeding risk and thrombosis, impaired clotting and health-related quality of life, as well as greater fatigue. 

“People living with immune thrombocytopenia who cannot tolerate or do not respond to medications aimed at raising platelet counts are at risk of uncontrolled bleeding and often endure side effects from steroids and other available therapies,” Kuter noted in a Sanofi news release

Rilzabrutinib, which received fast-track designation in November 2020 from the US Food and Drug Administration to treat immune thrombocytopenia, is currently under regulatory review and has a target action date of August 29, 2025. 

In the LUNA 3 study, adults with persistent or chronic immune thrombocytopenia and severely low platelet counts (median, 15,000/μL) received oral rilzabrutinib 400 mg twice a day (133 patients) or placebo (69 patients) for up to 24 weeks during a blinded treatment period, followed by a 28-week open-label period.

Platelet response — defined as counts at or above 50,000/μL or counts between 30,000/μL and 50,000/μL but doubled from baseline — was achieved in nearly two thirds of patients taking rilzabrutinib compared with almost one third of patients taking placebo at week 13. 

The primary endpoint was durable platelet response, defined as the proportion of patients able to achieve platelet counts at or above 50,000/μL for at least eight out of the last 12 weeks of the 24-week blinded period, without the need for rescue therapy. 

No patient taking placebo met this endpoint, compared with 23% of patients taking rilzabrutinib (P < .0001).

For the combined double-blind and open-label periods, a durable response was achieved in 29% of the 133 patients randomized to rilzabrutinib and 25% of the 193 patients receiving the drug in the open-label period at the data cutoff. 

Rilzabrutinib also led to significant improvements in bleeding (based on the Immune Thrombocytopenic Purpura Bleeding Score), with a mean change from baseline at week 25 of –0.04 with rilzabrutinib versus 0.05 with placebo (P = .0006).

Patients on rilzabrutinib were three times more likely to achieve a platelet response than their peers on placebo (hazard ratio, 3.1; P < .0001), with a median time to first platelet response of 36 days (vs median not achieved by patients on placebo). Among patients randomized to rilzabrutinib who achieved a response, the median time to response was 15 days.

Compared with placebo, rilzabrutinib significantly reduced the need for rescue therapy by 52% (P = .0007).

Rilzabrutinib was also associated with significant and sustained improvement in physical fatigue (based on the Immune Thrombocytopenic Purpura Patient Assessment Questionnaire [ITP-PAQ] Item 10 score).

“To our surprise, those patients who got active therapy but did not have a durable response still had an improvement in their fatigue levels and that suggests rilzabrutinib may affect fatigue or have anti-inflammatory properties since BTK inhibition has many different elements to it,” Kuter said during the briefing. 

The most common treatment-related adverse events with rilzabrutinib versus placebo were mild to moderate (grade 1/2) diarrhea (23% vs 4%), nausea (17% vs 6%), headache (8% vs 1%), and abdominal pain (6% vs 1%). Rates of grade 2 or higher gastrointestinal adverse events were comparable between groups: 6% with rilzabrutinib versus 4% with placebo. In the rilzabrutinib group, one patient who had numerous risk factors had a treatment-related grade 3 peripheral embolism and one patient died due to pneumonia unrelated to treatment.

“I’m encouraged by the robust therapeutic effects I’ve seen in patients of the LUNA 3 study across all aspects of the disease, including clinically meaningful and sustained improvements in platelet count, quality of life metrics, reduction in bleeding, and a favorable safety profile,” Kuter said in the Sanofi news release. 

The LUNA 3 study was funded by Sanofi. Kuter has disclosed various relationships with Sanofi and other pharmaceutical companies.

Mon, 12/09/2024 - 11:04

— Groundbreaking studies into leukemia treatments and the effects of glucagon-like peptide 1 (GLP-1) inhibitors on venous thromboembolism (VTE) risk will be presented at the American Society of Hematology (ASH) 2024 Annual Meeting, according to association leaders who spoke in a media preview session. Here’s a closer look at some of the highlighted research.

Children’s Disorders: Major Progress in B-Cell Acute Lymphoblastic Leukemia (B-ALL), Immune Thrombocytopenic Purpura (ITP)

While B-ALL is the most common childhood cancer and one of the most treatable, some patients face grim outcomes after they relapse following chemotherapy, said Cynthia E. Dunbar, MD, chief of the Translational Stem Cell Biology Branch at the National Heart, Lung, and Blood Institute.

new study reports that adding the targeted cancer drug blinatumomab (Blincyto) to chemotherapy boosted disease-free survival in standard-risk pediatric patients. “They definitively demonstrate a benefit with the addition of this immunotherapeutic drug, achieving 97% disease-free survival at 3 years on the blinatumomab plus chemotherapy arm compared to 90% for the control arm with standard therapies alone,” Dunbar said. “This trial will establish the addition of blinatumomab for childhood B-ALL as standard of care.”

A reporter asked Dunbar about the risk for severe immune activation syndrome. “These immune cell engagers can result in cytokine release syndrome and other severe immune activation consequences,” she said. “However, it appears that children seem to be less susceptible to those, at least in terms of severity, than adults. In this study, the complications that occurred didn’t result in mortality and were easily treatable. So that was not a major drawback to the addition of this drug.”

The blinatumomab study is sponsored by Children’s Oncology Group.

In ITP, thrombopoietin (TPO) agonists such as eltrombopag (Promacta) are a mainstay of second- or third-line treatment in children and adults with severe cases, Dunbar said. “However, TPO agonists are generally only given after months to years of failures of corticosteroids, IVIG [intravenous immunoglobulin], or splenectomy.”

In the phase 3, randomized, controlled PINES trial, researchers explored whether the drug could improve outcomes in children with untreated or very recent-onset severe ITP vs standard of care.

“The children treated with eltrombopag had double the response rate with a much lower need for rescue therapies,” Dunbar said. The percentage of patients who received rescue therapy was 19% in the eltrombopag arm (15/78) vs 46% in the control arm (18/39, P = .002).

“Given the potential short- and long-term consequences of corticosteroids and other standard treatments in children, this study is encouraging and will likely result in a change in the standard of care for pediatric ITP,” Dunbar said.

The eltrombopag study is sponsored by the ITP Consortium of North America and funded by Novartis.

 

Fewer Blood Clots: Another Big Benefit for Weight Loss Drugs?

Mikkael A. Sekeres, MD, MS, of the Sylvester Comprehensive Cancer Center at the University of Miami in Florida, highlighted an analysis of whether GLP-1 receptor agonists, initially approved as type 2 diabetes treatments, affect the risk for VTE.

Researchers tracked patients with type 2 diabetes — 366,369 who received the drugs and 290,219 who took dipeptidyl peptidase 4 inhibitors. The patients who took GLP-1 agonists “had lower rates of venous thromboembolic events after 1 year,” Sekeres said. “The risk reduction was actually pretty substantial.”

In these patients, the risk for VTE was 18% lower (hazard ratio [HR], 0.82; 95% CI, 0.77-0.88), and there were 22% and 15% reductions in pulmonary embolisms and deep venous thrombosis, respectively (HR, 0.78; 95% CI, 0.71-0.86 and HR, 0.85; 95% CI, 0.79-0.92).

 

Drug Regimen Improves Outcomes in Chronic Lymphocytic Leukemia (CLL)

An interim analysis of an open-label, randomized, phase 3 trial of patients with untreated CLL “demonstrated superior progression-free survival with acalabrutinib and venetoclax versus what we consider more classic chemotherapy of fludarabine, Cytoxan [cyclophosphamide], and rituximab or bendamustine and rituximab,” Sekeres said. “Similar findings were seen with acalabrutinib, venetoclax, and obinutuzumab vs that classic chemotherapy.”

Overall response rates were 93% for both the acalabrutinib/venetoclax regimens vs 75% for bendamustine/rituximab, Sekeres noted, and overall survival was higher for acalabrutinib/venetoclax vs the two classic chemotherapy regimens (HR, 0.33; P < .0001).

However, Sekeres questioned the value of comparing acalabrutinib/venetoclax with classical chemotherapy regimens. “A lot of times we have a lot of new, really good, really effective therapy to offer to patients that isn’t as toxic as previous chemotherapy.”

In contrast, fludarabine, cyclophosphamide, and rituximab are “your grandmother’s or your grandfather’s chemotherapy. It’s pretty toxic stuff,” he said.

Sekeres said it would have been better to compare acalabrutinib/venetoclax with a Bruton tyrosine kinase inhibitor–based regimen.

The German CLL Study Group is listed as the trial’s sponsor, and AstraZeneca is a collaborator. Dunbar disclosed research funding from Novartis. Sekeres had no relevant disclosures.

On Second Thought: Aspirin for Primary Prevention — What We Really Know

This transcript has been edited for clarity

Aspirin. Once upon a time, everybody over age 50 years was supposed to take a baby aspirin. Now we make it a point to tell people to stop. What is going on?  

Our recommendations vis-à-vis aspirin have evolved at a dizzying pace. The young’uns watching us right now don’t know what things were like in the 1980s. The Reagan era was a wild, heady time where nuclear war was imminent and we didn’t prescribe aspirin to patients. 

That only started in 1988, which was a banner year in human history. Not because a number of doves were incinerated by the lighting of the Olympic torch at the Seoul Olympics — look it up if you don’t know what I’m talking about — but because 1988 saw the publication of the ISIS-2 trial, which first showed a mortality benefit to prescribing aspirin post–myocardial infarction (MI).

Giving patients aspirin during or after a heart attack is not controversial. It’s one of the few things in this business that isn’t, but that’s secondary prevention — treating somebody after they develop a disease. Primary prevention, treating them before they have their incident event, is a very different ballgame. Here, things are messy. 

For one thing, the doses used have been very inconsistent. We should point out that the reason for 81 mg of aspirin is very arbitrary and is rooted in the old apothecary system of weights and measurements. A standard dose of aspirin was 5 grains, where 20 grains made 1 scruple, 3 scruples made 1 dram, 8 drams made 1 oz, and 12 oz made 1 lb - because screw you, metric system. Therefore, 5 grains was 325 mg of aspirin, and 1 quarter of the standard dose became 81 mg if you rounded out the decimal. 

People have tried all kinds of dosing structures with aspirin prophylaxis. The Physicians’ Health Study used a full-dose aspirin, 325 mg every 2 days, while the Hypertension Optimal Treatment (HOT) trial tested 75 mg daily and the Women’s Health Study tested 100 mg, but every other day. 

Ironically, almost no one has studied 81 mg every day, which is weird if you think about it. The bigger problem here is not the variability of doses used, but the discrepancy when you look at older vs newer studies.

Older studies, like the Physicians’ Health Study, did show a benefit, at least in the subgroup of patients over age 50 years, which is probably where the “everybody over 50 should be taking an aspirin” idea comes from, at least as near as I can tell. 

More recent studies, like the Women’s Health Study, ASPREE, or ASPIRE, didn’t show a benefit. I know what you’re thinking: Newer stuff is always better. That’s why you should never trust anybody over age 40 years. The context of primary prevention studies has changed. In the ‘80s and ‘90s, people smoked more and we didn’t have the same medications that we have today. We talked about all this in the beta-blocker video to explain why beta-blockers don’t seem to have a benefit post MI.

We have a similar issue here. The magnitude of the benefit with aspirin primary prevention has decreased because we’re all just healthier overall. So, yay! Progress! Here’s where the numbers matter. No one is saying that aspirin doesn’t help. It does. 

If we look at the 2019 meta-analysis published in JAMA, there is a cardiovascular benefit. The numbers bear that out. I know you’re all here for the math, so here we go. Aspirin reduced the composite cardiovascular endpoint from 65.2 to 60.2 events per 10,000 patient-years; or to put it more meaningfully in absolute risk reduction terms, because that’s my jam, an absolute risk reduction of 0.41%, which means a number needed to treat of 241, which is okay-ish. It’s not super-great, but it may be justifiable for something that costs next to nothing. 

The tradeoff is bleeding. Major bleeding increased from 16.4 to 23.1 bleeds per 10,000 patient-years, or an absolute risk increase of 0.47%, which is a number needed to harm of 210. That’s the problem. Aspirin does prevent heart disease. The benefit is small, for sure, but the real problem is that it’s outweighed by the risk of bleeding, so you’re not really coming out ahead. 

The real tragedy here is that the public is locked into this idea of everyone over age 50 years should be taking an aspirin. Even today, even though guidelines have recommended against aspirin for primary prevention for some time, data from the National Health Interview Survey sample found that nearly one in three older adults take aspirin for primary prevention when they shouldn’t be. That’s a large number of people. That’s millions of Americans — and Canadians, but nobody cares about us. It’s fine. 

That’s the point. We’re not debunking aspirin. It does work. The benefits are just really small in a primary prevention population and offset by the admittedly also really small risks of bleeding. It’s a tradeoff that doesn’t really work in your favor.

But that’s aspirin for cardiovascular disease. When it comes to cancer or DVT prophylaxis, that’s another really interesting story. We might have to save that for another time. Do I know how to tease a sequel or what?

Labos, a cardiologist at Kirkland Medical Center, Montreal, Quebec, Canada, has disclosed no relevant financial relationships.

Even today, even though guidelines have recommended against aspirin for primary prevention for some time, data from the National Health Interview Survey sample found that nearly one in three older adults take aspirin for primary prevention when they shouldn’t be. That’s a large number of people. That’s millions of Americans — and Canadians, but nobody cares about us. It’s fine. 

That’s the point. We’re not debunking aspirin. It does work. The benefits are just really small in a primary prevention population and offset by the admittedly also really small risks of bleeding. It’s a tradeoff that doesn’t really work in your favor.

But that’s aspirin for cardiovascular disease. When it comes to cancer or DVT prophylaxis, that’s another really interesting story. We might have to save that for another time. Do I know how to tease a sequel or what?

Current Hydroxychloroquine Use in Lupus May Provide Protection Against Cardiovascular Events

Article Type
Changed
Wed, 09/11/2024 - 14:33

 

TOPLINE:

Current use of hydroxychloroquine is associated with a lower risk for myocardial infarction (MI), stroke, and other thromboembolic events in patients with systemic lupus erythematosus (SLE). This protective effect diminishes after discontinuation of hydroxychloroquine treatment.

METHODOLOGY:

  • Researchers used a nested case-control design to evaluate the association between exposure to hydroxychloroquine and the risk for cardiovascular events in patients with SLE.
  • They included 52,883 adults with SLE (mean age, 44.23 years; 86.6% women) identified from the National System of Health Databases, which includes 99% of the French population.
  • Among these, 1981 individuals with composite cardiovascular conditions were matched with 16,892 control individuals without cardiovascular conditions.
  • Patients were categorized on the basis of hydroxychloroquine exposure into current users (last exposure within 90 days before a cardiovascular event), remote users (91-365 days before), and nonusers (no exposure within 365 days).
  • The study outcomes included a composite of cardiovascular events, including MI, stroke (including transient ischemic attack), and other thromboembolic events such as phlebitis, thrombophlebitis, venous thrombosis, venous thromboembolism, and pulmonary embolism.

TAKEAWAY:

  • Current hydroxychloroquine users had lower odds of experiencing a composite cardiovascular outcome than nonusers (adjusted odds ratio [aOR], 0.63; 95% CI, 0.57-0.70).
  • The odds of MI (aOR, 0.72; 95% CI, 0.60-0.87), stroke (aOR, 0.71; 95% CI, 0.61-0.83), and other thromboembolic events (aOR, 0.58; 95% CI, 0.48-0.69) were also lower among current users than among nonusers.
  • No significant association was found for remote hydroxychloroquine exposure and the risk for composite cardiovascular events, MI, stroke, and other thromboembolic events.

IN PRACTICE:

“These findings support the protective association of hydroxychloroquine against CV [cardiovascular] events and underscore the importance of continuous hydroxychloroquine therapy for patients diagnosed with SLE,” the authors wrote.

SOURCE:

The study was led by Lamiae Grimaldi-Bensouda, PharmD, PhD, Department of Pharmacology, Hospital Group Paris-Saclay, Assistance Publique-Hôpitaux de Paris, France. It was published online on August 30, 2024, in JAMA Network Open.

LIMITATIONS:

The observational nature of the study may have introduced confounding. Current hydroxychloroquine users were younger than nonusers, with an average age difference of almost 5 years. Current hydroxychloroquine users had a twofold longer duration of onset of SLE and had a higher prevalence of chronic kidney disease compared with nonusers.

DISCLOSURES:

This study was funded by the Banque pour l’Investissement, Deeptech. Some authors declared having financial ties with various institutions and companies outside of the current study.

Just A Single Night of Poor Sleep May Change Serum Proteins

Article Type
Changed
Tue, 08/27/2024 - 10:40

A single night of sleep deprivation had a significant impact on human blood serum, based on new data from an analysis of nearly 500 proteins. Compromised sleep has demonstrated negative effects on cardiovascular, immune, and neuronal systems, and previous studies have shown human serum proteome changes after a simulation of night shift work, wrote Alvhild Alette Bjørkum, MD, of Western Norway University of Applied Sciences, Bergen, and colleagues.

In a pilot study published in Sleep Advances, the researchers recruited eight healthy adult women aged 22-57 years with no history of neurologic or psychiatric problems to participate in a study of the effect of compromised sleep on protein profiles, with implications for effects on cells, tissues, and organ systems. Each of the participants served as their own controls, and blood samples were taken after 6 hours of sleep at night, and again after 6 hours of sleep deprivation the following night.

The researchers identified analyzed 494 proteins using mass spectrometry. Of these, 66 were differentially expressed after 6 hours of sleep deprivation. The top enriched biologic processes of these significantly changed proteins were protein activation cascade, platelet degranulation, blood coagulation, and hemostasis.

Further analysis using gene ontology showed changes in response to sleep deprivation in biologic process, molecular function, and immune system process categories, including specific associations related to wound healing, cholesterol transport, high-density lipoprotein particle receptor binding, and granulocyte chemotaxis.

The findings were limited by several factors including the small sample size, inclusion only of adult females, and the use of data from only 1 night of sleep deprivation, the researchers noted. However, the results support previous studies showing a negative impact of sleep deprivation on biologic functions, they said.

“Our study was able to reveal another set of human serum proteins that were altered by sleep deprivation and could connect similar biological processes to sleep deprivation that have been identified before with slightly different methods,” the researchers concluded. The study findings add to the knowledge base for the protein profiling of sleep deprivation, which may inform the development of tools to manage lack of sleep and mistimed sleep, particularly in shift workers.
 

Too Soon for Clinical Implications

“The adverse impact of poor sleep across many organ systems is gaining recognition, but the mechanisms underlying sleep-related pathology are not well understood,” Evan L. Brittain, MD, of Vanderbilt University, Nashville, Tennessee, said in an interview. “Studies like this begin to shed light on the mechanisms by which poor or reduced sleep affects specific bodily functions,” added Dr. Brittain, who was not involved in the study.

“The effects of other acute physiologic stressor such as exercise on the circulating proteome are well described. In that regard, it is not surprising that a brief episode of sleep deprivation would lead to detectable changes in the circulation,” Dr. Brittain said.

However, the specific changes reported in this study are difficult to interpret because of methodological and analytical concerns, particularly the small sample size, lack of an external validation cohort, and absence of appropriate statistical adjustments in the results, Dr. Brittain noted. These limitations prevent consideration of clinical implications without further study.

The study received no outside funding. Neither the researchers nor Dr. Brittain disclosed any conflicts of interest.

New Study Links Sweetener to Heart Risk: What to Know

Article Type
Changed
Mon, 08/12/2024 - 12:04

Is going sugar free really good advice for patients with cardiometabolic risk factors? 

That’s the question raised by new Cleveland Clinic research, which suggests that consuming erythritol, a sweetener widely found in sugar-free and keto food products, could spur a prothrombotic response. 

In the study, published in Arteriosclerosis, Thrombosis, and Vascular Biology, 10 healthy participants ate 30 grams of erythritol. Thirty minutes later, their blood showed enhanced platelet aggregation and increased markers of platelet responsiveness and activation. 

Specifically, the researchers saw enhanced stimulus-dependent release of serotonin (a marker of platelet dense granules) and CXCL4 (a platelet alpha-granule marker). 

“ With every single person, you see a prothrombotic effect with every single test that we did,” said study author Stanley Hazen, MD, PhD, chair of the Department of Cardiovascular & Metabolic Sciences at Cleveland Clinic in Ohio. By contrast, participants who ate 30 grams of glucose saw no such effect. 

The erythritol itself does not activate the platelets, Dr. Hazen said, rather it lowers the threshold for triggering a response. This could make someone more prone to clotting, raising heart attack and stroke risk over time.

Though the mechanism is unknown, Dr. Hazen has an idea. 

“There appears to be a receptor on platelets that is recognizing and sensing these sugar alcohols,” Dr. Hazen said, “much in the same way your taste bud for sweet is a receptor for recognizing a glucose or sugar molecule.” 

“We’re very interested in trying to figure out what the receptor is,” Dr. Hazen said, “because I think that then becomes a very interesting potential target for further investigation and study into how this is linked to causing heart disease.”
 

The Past and Future of Erythritol Research

In 2001, the Food and Drug Administration classified erythritol as a “generally recognized as safe” food additive. A sugar alcohol that occurs naturally in foods like melon and grapes, erythritol is also manufactured by fermenting sugars. It’s about 70% as sweet as table sugar. Humans also produce small amounts of erythritol naturally: Our blood cells make it from glucose via the pentose phosphate pathway

Previous research from Dr. Hazen’s group linked erythritol to a risk for major adverse cardiovascular events and clotting. 

“Based on their previous study, I think this was a really important study to do in healthy individuals,” said Martha Field, PhD, assistant professor in the Division of Nutritional Sciences at Cornell University, Ithaca, New York, who was not involved in the study.

The earlier paper analyzed blood samples from participants with unknown erythritol intake, including some taken before the sweetener, and it was as widespread as it is today. That made disentangling the effects of eating erythritol vs naturally producing it more difficult. 

By showing that eating erythritol raises markers associated with thrombosis, the new paper reinforces the importance of thinking about and developing a deeper understanding of what we put into our bodies. 

“This paper was conducted in healthy individuals — might this be particularly dangerous for individuals who are at increased risk of clotting?” asked Dr. Field. “There are lots of genetic polymorphisms that increase your risk for clotting disorders or your propensity to form thrombosis.” 

Field would like to see similar analyses of xylitol and sorbitol, other sugar alcohols found in sugar-free foods. And she called for more studies on erythritol that look at lower erythritol consumption over longer time periods. 

Registered dietitian nutritionist Valisa E. Hedrick, PhD, agreed: Much more work is needed in this area, particularly in higher-risk groups, such as those with prediabetes and diabetes, said Dr. Hedrick, an associate professor in the Department of Human Nutrition, Foods, and Exercise at Virginia Tech, Blacksburg, who was not involved in the study. 

“Because this study was conducted in healthy individuals, the impact of a small dose of glucose was negligible, as their body can effectively regulate blood glucose levels,” she said. “Because high blood glucose concentrations have also been shown to increase platelet reactivity, and consequently increase thrombosis potential, individuals who are not able to regulate their blood glucose levels, such as those with prediabetes and diabetes, could potentially see a similar effect on the body as erythritol when consuming large amounts of sugar.” 

At the same time, “individuals with diabetes or prediabetes may be more inclined to consume erythritol as an alternative to sugar,” Dr. Hedrick added. “It will be important to design studies that include these individuals to determine if erythritol has an additive adverse effect on cardiac event risk.”
 

 

 

Criticism and Impact 

Critics have suggested the 30-gram dose of erythritol ingested by study participants is unrealistic. Dr. Hazen said that it’s not. 

Erythritol is often recommended as a one-to-one sugar replacement. And you could top 30 grams with a few servings of erythritol-sweetened ice cream or soda, Dr. Hazen said. 

“The dose that we used, it’s on the high end, but it’s well within a physiologically relevant level,” he said. 

Still others say the results are only relevant for people with preexisting heart trouble. But Dr. Hazen said they matter for the masses. 

“I think there’s a significant health concern at a population level that this work is underscoring,” he said. 

After all, heart disease risk factors like obesity, hypertension, diabetes, and smoking are common and quickly add up. 

“If you look at middle-aged America, most people who experience a heart attack or stroke do not know that they have coronary artery disease, and the first recognition of it is that event,” Dr. Hazen said. 

For now, Dr. Hazen recommends eating real sugar in moderation. He hopes future research will reveal a nonnutritive sweetener that doesn’t activate platelets. 
 

The Bigger Picture

The new research adds yet another piece to the puzzle of whether nonnutritive sweeteners are better than sugar. 

“I think these results are concerning,” said JoAnn E. Manson, MD, chief of the Division of Preventive Medicine at Brigham and Women’s Hospital and a professor of medicine at Harvard Medical School, both in Boston, Massachusetts. They “ may help explain the surprising results in some observational studies that artificial sweeteners are linked to an increased risk of cardiovascular disease.”

Dr. Manson, who was not involved in the new study, has conducted other research linking artificial sweetener use with stroke risk.

In an upcoming randomized clinical study, her team is comparing head-to-head sugar-sweetened beverages, drinks sweetened with calorie-free substitutes, and water to determine which is best for a range of cardiometabolic outcomes. 

“We need more research on this question,” she said, “because these artificial sweeteners are commonly used, and many people are assuming that their health outcomes will be better with the artificial sweeteners than with sugar-sweetened products.”

“If you look at middle-aged America, most people who experience a heart attack or stroke do not know that they have coronary artery disease, and the first recognition of it is that event,” Dr. Hazen said. 

For now, Dr. Hazen recommends eating real sugar in moderation. He hopes future research will reveal a nonnutritive sweetener that doesn’t activate platelets. 
 

The Bigger Picture

The new research adds yet another piece to the puzzle of whether nonnutritive sweeteners are better than sugar. 

“I think these results are concerning,” said JoAnn E. Manson, MD, chief of the Division of Preventive Medicine at Brigham and Women’s Hospital and a professor of medicine at Harvard Medical School, both in Boston, Massachusetts. They “ may help explain the surprising results in some observational studies that artificial sweeteners are linked to an increased risk of cardiovascular disease.”

Dr. Manson, who was not involved in the new study, has conducted other research linking artificial sweetener use with stroke risk.

In an upcoming randomized clinical study, her team is comparing head-to-head sugar-sweetened beverages, drinks sweetened with calorie-free substitutes, and water to determine which is best for a range of cardiometabolic outcomes. 

“We need more research on this question,” she said, “because these artificial sweeteners are commonly used, and many people are assuming that their health outcomes will be better with the artificial sweeteners than with sugar-sweetened products.”

Is going sugar free really good advice for patients with cardiometabolic risk factors? 

That’s the question raised by new Cleveland Clinic research, which suggests that consuming erythritol, a sweetener widely found in sugar-free and keto food products, could spur a prothrombotic response. 

In the study, published in Arteriosclerosis, Thrombosis, and Vascular Biology, 10 healthy participants ate 30 grams of erythritol. Thirty minutes later, their blood showed enhanced platelet aggregation and increased markers of platelet responsiveness and activation. 

Specifically, the researchers saw enhanced stimulus-dependent release of serotonin (a marker of platelet dense granules) and CXCL4 (a platelet alpha-granule marker). 

“ With every single person, you see a prothrombotic effect with every single test that we did,” said study author Stanley Hazen, MD, PhD, chair of the Department of Cardiovascular & Metabolic Sciences at Cleveland Clinic in Ohio. By contrast, participants who ate 30 grams of glucose saw no such effect. 

The erythritol itself does not activate the platelets, Dr. Hazen said, rather it lowers the threshold for triggering a response. This could make someone more prone to clotting, raising heart attack and stroke risk over time.

Though the mechanism is unknown, Dr. Hazen has an idea. 

“There appears to be a receptor on platelets that is recognizing and sensing these sugar alcohols,” Dr. Hazen said, “much in the same way your taste bud for sweet is a receptor for recognizing a glucose or sugar molecule.” 

“We’re very interested in trying to figure out what the receptor is,” Dr. Hazen said, “because I think that then becomes a very interesting potential target for further investigation and study into how this is linked to causing heart disease.”
 

The Past and Future of Erythritol Research

In 2001, the Food and Drug Administration classified erythritol as a “generally recognized as safe” food additive. A sugar alcohol that occurs naturally in foods like melon and grapes, erythritol is also manufactured by fermenting sugars. It’s about 70% as sweet as table sugar. Humans also produce small amounts of erythritol naturally: Our blood cells make it from glucose via the pentose phosphate pathway

Previous research from Dr. Hazen’s group linked erythritol to a risk for major adverse cardiovascular events and clotting. 

“Based on their previous study, I think this was a really important study to do in healthy individuals,” said Martha Field, PhD, assistant professor in the Division of Nutritional Sciences at Cornell University, Ithaca, New York, who was not involved in the study.

The earlier paper analyzed blood samples from participants with unknown erythritol intake, including some taken before the sweetener, and it was as widespread as it is today. That made disentangling the effects of eating erythritol vs naturally producing it more difficult. 

By showing that eating erythritol raises markers associated with thrombosis, the new paper reinforces the importance of thinking about and developing a deeper understanding of what we put into our bodies. 

“This paper was conducted in healthy individuals — might this be particularly dangerous for individuals who are at increased risk of clotting?” asked Dr. Field. “There are lots of genetic polymorphisms that increase your risk for clotting disorders or your propensity to form thrombosis.” 

Field would like to see similar analyses of xylitol and sorbitol, other sugar alcohols found in sugar-free foods. And she called for more studies on erythritol that look at lower erythritol consumption over longer time periods. 

Registered dietitian nutritionist Valisa E. Hedrick, PhD, agreed: Much more work is needed in this area, particularly in higher-risk groups, such as those with prediabetes and diabetes, said Dr. Hedrick, an associate professor in the Department of Human Nutrition, Foods, and Exercise at Virginia Tech, Blacksburg, who was not involved in the study. 

“Because this study was conducted in healthy individuals, the impact of a small dose of glucose was negligible, as their body can effectively regulate blood glucose levels,” she said. “Because high blood glucose concentrations have also been shown to increase platelet reactivity, and consequently increase thrombosis potential, individuals who are not able to regulate their blood glucose levels, such as those with prediabetes and diabetes, could potentially see a similar effect on the body as erythritol when consuming large amounts of sugar.” 

At the same time, “individuals with diabetes or prediabetes may be more inclined to consume erythritol as an alternative to sugar,” Dr. Hedrick added. “It will be important to design studies that include these individuals to determine if erythritol has an additive adverse effect on cardiac event risk.”
 

 

 

Criticism and Impact 

Critics have suggested the 30-gram dose of erythritol ingested by study participants is unrealistic. Dr. Hazen said that it’s not. 

Erythritol is often recommended as a one-to-one sugar replacement. And you could top 30 grams with a few servings of erythritol-sweetened ice cream or soda, Dr. Hazen said. 

“The dose that we used, it’s on the high end, but it’s well within a physiologically relevant level,” he said. 

Still others say the results are only relevant for people with preexisting heart trouble. But Dr. Hazen said they matter for the masses. 

“I think there’s a significant health concern at a population level that this work is underscoring,” he said. 

After all, heart disease risk factors like obesity, hypertension, diabetes, and smoking are common and quickly add up. 

“If you look at middle-aged America, most people who experience a heart attack or stroke do not know that they have coronary artery disease, and the first recognition of it is that event,” Dr. Hazen said.

Why Are We Undertreating So Many Pulmonary Embolisms?

Article Type

Thu, 06/06/2024 - 13:30

A small fraction of patients with pulmonary embolism (PE) who are eligible for advanced therapies are actually getting them, reported investigators who conducted a big data analysis.

“Advanced PE therapy seems to be vulnerable to disparate use, and perhaps underuse,” Sahil Parikh, MD, a cardiovascular interventionalist at the Columbia University Medical Center in New York, said when he presented results from the REAL-PE study at the Society for Cardiovascular Angiography and Interventions (SCAI) 2024 Scientific Sessions.

The underuse of advanced PE therapies is “the controversy,” Dr. Parikh said after his presentation. “It remains unclear what the role of invasive therapy is in the management of so-called high-intermediate–risk people. There isn’t a Class 1 guideline recommendation, and there is a very rapidly evolving trend that we’re increasingly treating these patients invasively,” he said.

“However, if you come to these meetings [such as SCAI], you might think everyone is getting one of these devices, but these data show that’s not the case,” Dr. Parikh said.

The analysis mined deidentified data from Truveta, a collective of health systems that provides regulatory-grade electronic health record data for research. The database included 105 million diagnoses made from January 1, 2018, to May 5, 2023; according to the diagnosis codes, 435,296 of these were for pulmonary embolism, and according to the procedure codes, 2072 patients — 0.48% of all patients with a PE diagnosis — received advanced therapy.

The researchers accessed data on patients treated with ultrasound-assisted catheter-directed thrombolysis or mechanical thrombectomy, identified from claims codes. Patient characteristics — age, race, ethnicity, sex, comorbidities, and diagnoses — were also accessed for the analysis. Earlier results were published in the January issue of the Journal of the Society for Cardiovascular Angioplasty Interventions
 

Less Intervention for Black Patients and Women

White patients were more likely to receive advanced therapy than were Black patients (0.5% vs 0.37%; P = .000), Dr. Parikh reported, and women were less likely to receive advanced therapy than were men (0.41% vs 0.55%; P = .000).

The only discernable differences in outcomes were in major bleeding events in the 7 days after the procedure, which affected more White patients than it did Black patients (13.9% vs 9.3%) and affected more women than it did men (16.6% vs 11.1%).

What’s noteworthy about this study is that it demonstrates the potential of advanced data analytics to identify disparities in care and outcomes, Dr. Parikh said during his presentation. “These analyses provide a means of evaluating disparities in real clinical practice, both in the area of PE and otherwise, and may also be used for real-time monitoring of clinical decision-making and decisional support,” he said. “We do think that both novel and established therapies can benefit equally from similar types of analyses.”
 

Big Data Signaling Disparities

“That’s where these data are helpful,” Dr. Parikh explained. They provide “a real snapshot of how many procedures are being performed and in what kinds of patients. The low number of patients getting the procedure would suggest that there are probably more patients who would be eligible for treatment based on some of the emerging consensus documents, and they’re not receiving them.”

The data are “hypotheses generating,” Dr. Parikh said in an interview. “These hypotheses have to be evaluated further in more granular databases.”

REAL-PE is also a “clarion call” for clinical trials of investigative devices going forward, he said. “In those trials, we need to endeavor to enroll enough women and men, minority and nonminority patients so that we can make meaningful assessments of differences in efficacy and safety.”

This study is “real proof that big data can be used to provide information on outcomes for patients in a very rapid manner; that’s really exciting,” said Ethan Korngold, MD, chair of structural and interventional cardiology at the Providence Health Institute in Portland, Oregon. “This is an area of great research with great innovation, and it’s proof that, with these type of techniques using artificial intelligence and big data, we can generate data quickly on how we’re doing and what kind of patients we’re reaching.”

Findings like these may also help identify sources of the disparities, Dr. Korngold added. 

“This shows we need to be reaching every patient with advanced therapies,” he said. “Different hospitals have different capabilities and different expertise in this area and they reach different patient populations. A lot of the difference in utilization stems from this fact,” he said.

“It just underscores the fact that we need to standardize our treatment approaches, and then we need to reach every person who’s suffering from this disease,” Dr. Korngold said.
