MILAN – Sotatercept, a first-in-class activin signaling inhibitor, is currently under scrutiny as a potential game-changer in the treatment of pulmonary arterial hypertension (PAH). Data unveiled at the annual congress of the European Respiratory Society, held in Milan, suggest that sotatercept treatment has the capacity to deliver significant clinical benefits and could reshape the trajectory of this challenging disease. Experts are cautiously optimistic that this drug may soon find a place within the PAH treatment algorithm.

The STELLAR trial: A milestone in PAH research

PAH is intricately linked to the dysregulation of members within the TGF-beta superfamily, including activin receptor type IIA (ActRIIA) and its ligands activin A and activin B. This signaling pathway is believed to be a driving force behind the pulmonary vascular remodeling observed in PAH patients. Sotatercept, a fusion protein acting as a ligand trap for selected TGF-beta superfamily members, has been proposed to recalibrate pulmonary vascular homeostasis by promoting growth-inhibiting and pro-apoptotic signaling.

Sotatercept was tested first in a phase 2 trial (PULSAR) and later in a phase 3 trial (STELLAR). The STELLAR clinical trial, funded by Acceleron Pharma (now a subsidiary of Merck), was the subject of two presentations given by Marius M. Hoeper, MD, director of the department of respiratory medicine at Hannover Medical School, Hannover, Germany.  

Dr. Hoeper commented on results published in the New England Journal of Medicine during a session titled, “Disease modification in pulmonary arterial hypertension.” Later, during the “From the Editor’s Desk” session, he presented new results recently published in the European Respiratory Journal about the effects of sotatercept on hemodynamics and right heart function.
 

Disease modification in PAH

In his initial address, Dr. Hoeper expounded on the concept of reverse remodeling as a therapeutic avenue for PAH. “PAH is not a disease of pulmonary vasoconstriction,” he clarified, “but a disease of proliferation. Endothelial cells and pulmonary vascular muscle cells proliferate and obliterate the lumen. It has been hypothesized that when we target this system successfully, we may not only stop disease progression, but we may have a chance to have at least some reverse remodeling, because, if these cells go into apoptosis, there may be a partial reopening of the vessels.”

“Sotatercept is probably going to be a game changer in our field,” Dr. Hoeper continued. “Is sotatercept a disease-modifying agent? It certainly induces disease improvement; in a few patients, although not in the majority, we see a normalization of hemodynamics. We target the underlying pathophysiology; this is clearly distinct from symptomatic treatment.” Dr. Hoeper went through the list of characteristics that a disease-modifying agent should have.

“To be able to say that a drug endures sustained clinical benefit, according to the FDA, you need to withdraw the drug, and this is something we do not know. We know that we can interrupt the treatment once or twice, but long-term I do not believe that,” he said, while acknowledging the need for more extended-term safety and efficacy data.
 

Unmasking hemodynamic impact

Dr. Hoeper’s second presentation focused on a post hoc analysis of the STELLAR trial never presented before. He analyzed right heart catheterization (RHC) and echocardiography (ECHO) data. With sotatercept treatment at week 24, the researchers observed:

• A small increase in systemic blood pressure and systemic vascular resistance.
• No changes in systolic and diastolic volumes of the left ventricle (lv).
• A small but significant reduction in lv ejection fraction.
• A great reduction in the mean pulmonary artery pressure (mPAP).
• No change in cardiac output.
• An improvement in pulmonary artery compliance.
• A reduction in the right ventricle work and in right atrial pressure.
• An improvement of echocardiographic parameters, including a significant decrease in tricuspid regurgitation.

“A drop of roughly 14 mm Hg in mPAP is something that we have never seen in PAH with any other add-on medication. This was entirely driven by improvement in the sotatercept group, not by deterioration in the placebo group,” Dr. Hoeper pointed out. Of note, change in mPAP correlated with changes in NT-proNBP and with changes in 6-minute walk distance (6MWD), the primary endpoint of the STELLAR trial. “We effectively unload the right ventricle by lowing the artery pressure. What we observe is exactly what we want to achieve in patients with PAH, because the heart is what really matters,” he concluded.
 

A new course in PAH treatment?

Olivier Sitbon, MD, PhD, professor of respiratory medicine at Université Paris-Saclay and consultant at the French Referral Center for Pulmonary Hypertension, echoed Dr. Hoeper’s enthusiasm. “What is important about sotatercept studies is that for the first time it has been demonstrated that to add a fourth drug improves hemodynamics in PAH patients on background triple-combination therapy. Today, triple therapy is the maximum treatment before lung transplantation,” he told this news organization.

Dr. Sitbon highlighted ongoing studies with sotatercept, including the ZENITH trial, focused on high-risk PAH patients, and the HYPERION trial, aimed at patients diagnosed within the first year of their PAH journey. He acknowledged that experts currently lack consensus on the ideal position for sotatercept within the PAH treatment algorithm. However, he anticipates a lively debate and expects sotatercept to find its place as a second-line treatment for intermediate low-risk or intermediate high-risk patients, with potential consideration for high-risk patients.

“There are two more studies ongoing with sotatercept: the ZENITH trial, dedicated to PAH patients at high risk, whose primary endpoint is mortality/need for lung transplant, and the HYPERION trial, dedicated to patients diagnosed less than 1 year (not really newly diagnosed but quite incident, while patients included in previous trial were very prevalent), whose primary endpoint is time to clinical worsening,” Dr. Sitbon noted, pointing out that there is currently no consensus among the experts about where to place sotatercept in the PAH treatment algorithm.
 

Further insights into sotatercept

The ERS Congress also unveiled two additional studies that provided fresh perspectives on sotatercept’s potential. Ioana R. Preston, MD, from Tufts Medical Center in Boston, presented the first interim analysis of SOTERIA, a long-term follow-up study involving 409 patients with a median exposure duration of 462 days to sotatercept. Treatment-emergent adverse events (TEAEs) were reported by 80% of patients, with 20% reporting a serious TEAE. Overall, four serious TEAEs (1% of patients) led to death, but only five patients (1.2%) discontinued sotatercept because of TEAE.

Notably, improvements in clinical efficacy measures persisted after 1 year. During SOTERIA, roughly 3% of patients on any prostacyclin discontinued it. “Results of SOTERIA support the long-term durable clinical benefit and safety of sotatercept for the treatment of PAH. Of note, patients were offered home self-administration therapy, so they do not need to come back to the office,” Dr. Preston said.

A second late-breaking abstract presented by Vallerie McLaughlin, MD, University of Michigan, Ann Arbor, described the possible long-term impact of sotatercept on morbidity and mortality. STELLAR trial data were analyzed to see how the risk profile of patients changed in the 24 weeks of study. Real-world registry data from the COMPERA registry were then used to extrapolate mortality and transplant need over 30 years based on risk transition. According to the simulation model, adding sotatercept to background therapy is expected to increase life expectancy by threefold, while avoiding nearly 700 hospitalizations and four lung/heart-lung transplantations per 1,000 patients. “Real-world data are needed to confirm these findings,” cautioned Dr. McLaughlin.

Long-term follow-up from the CheckMate 227 study has revealed lasting benefit from the combination of the CTLA-4 inhibitor ipilimumab (IPI) and the PD-1 inhibitor nivolumab (NIVO) in non-small cell lung cancer. After 6 years, previous tumor response, tumor burden reduction, and baseline health-related quality of life all correlated with overall survival, according to the latest analysis from the study.

“Patients treated with NIVO-IPI versus chemotherapy continue to derive long term durable efficacy benefit in CheckMate 227, regardless of PD-L1 expression. This represents the longest ever reported follow-up across phase three studies of frontline immunotherapy in patients with metastatic non–small cell lung cancer, and this further highlights the clinical benefit of frontline NIVO-IPI as a treatment in these patients with metastatic non–small cell lung cancer, regardless of the PD-L1 expression,” said Solange Peters, MD, PhD, during a presentation of the latest analysis at the annual World Conference on Lung Cancer. Dr. Peters is a professor of oncology at Lausanne (Switzerland) University Hospital.

The combination of nivolumab and ipilimumab has shown long-term survival benefit in other cancer types, including advanced melanoma, advanced renal cell carcinoma, and unresectable pleural mesothelioma.

The same session featured other studies demonstrating positive outcomes of immunotherapy in NSCLC. Serving as a discussant, Ferdinandos Skoulidis MD, PhD, commented, “I would argue that we are now at an inflection point where we can claim that we are altering the natural history of the disease for a subset of patients.” Dr. Skoulidis is an associate professor of thoracic oncology at the University of Texas MD Anderson Cancer Center.
 

Updated results

CheckMate 227 enrolled patients with metastatic or recurrent NSCLC, excluding those with EGFR/ALK alterations. Patients with PD-L1 expression greater than or equal to 1% (PD-L1 positive, n = 1,189) were randomized to NIVO-IPI, NIVO, or chemotherapy. Patients with PD-L1 expression less than 1% (n = 550, PD-L1 negative) were randomized to NIVO-IPI, NIVO plus chemotherapy, or chemotherapy alone. The 5-year landmark analysis, which was published by the National Center for Biotechnology Information, showed overall survival rate of 24% among PD-L1 greater than or equal to 1% patients (PD-L1 positive) and 19% in PD-L1 less than 1% (PD-L1 negative) patients who received IPI-NIVO therapy, compared with 14% and 7%, respectively, in the chemotherapy only groups.

At WCLC, Dr. Peters presented data extending to 6 years of follow-up, as well as exploratory analyses. At 6 years of follow-up, in PD-L1 positive patients, 22% of the NIVO-IPI group remained alive, versus 13% of the chemotherapy group (hazard ratio, 0.78; 95% confidence interval, 0.67-0.91), while there was no significant improvement in OS for nivolumab alone, compared with chemotherapy. In the PD-L1 negative group, 16% were alive at 6 years in the IPI-NIVO group (HR, 0.65; 95% CI, 0.52-0.81), as were 10% in NIVO plus chemotherapy (HR, 0.79; 95% CI, 0.64-0.98) group, versus 5% in the chemotherapy group. The benefit of NIVO-IPI was significant in both squamous and non-squamous tumors for both PDL1-positive and PD-L1 negative patients.

At 6 years follow-up, 27% of PD-L1 positive patients who responded to NIVO-IPI remained in response, versus 22% in the NIVO group and 4% in the chemotherapy only group. Among PD-L1 negative patients, 25% of combination therapy responders remained in response at 6 years, while there were 10% still in response among the NIVO group, and none in the chemotherapy only group.
 

Exploratory analyses

Dr. Peters presented a slide showing tumor burden reductions occurring in responders. “What has to be concluded from this very interesting graph is that there are more, deeper responses in the NIVO-IPI versus chemotherapy. Very importantly, too, this is strongly correlated with survival. In both treatment arms, a high magnitude of tumor burden reduction is correlated with an improved survival,” said Dr. Peters. Specifically, among PD-L1 positive patients with more than 80% tumor reduction, survival was 59% at 6 years (95% CI, 44-71%). The figure was 68% in the NIVO only arm (95% CI, 47-82%), and 42% in the chemotherapy only arm (95% CI, 15-66%).

Among PD-L1 negative patients, “there are more, deeper responses in NIVO-IPI versus chemotherapy. That is very clear. And probably differently from the positive PD-L1 arm, the tumor burden reduction is correlated with survival but really only strongly observed in the NIVO-IPI arm,” said Dr. Peters. The figure was 20% in the nivolumab arm (95% CI, 3-48%) and 0% in the chemotherapy only arm (95% CI, not available). “So really something is correlating the tumor burden reduction with the outcome and specifically correlating it in the negative PD-L1 with the treatment of NIVO-IPI,” said Dr. Peters.

The researchers also noted longer progression-free survival and overall response rate in the NIVO-IPI group than the chemotherapy group in both PD-L1 positive and PD-L1 negative patients.

With respect to health-related quality of life, the researchers found a correlation between higher scores at baseline on the EQ-5D-3L scale and overall survival in the chemotherapy group (HR, 0.61; 95% CI, 0.51-0.74) and a trend in the NIVO-IPI group (HR, 0.83; 95% CI, 0.69-1.01). “So this baseline history, the quality of life, is correlated with the outcome regardless of the treatment you deliver,” said Dr. Peters.
 

Personalizing immunotherapy in NSCLC

In his comments, Dr. Skoulidis highlighted the length of responses. “Most importantly, approximately 50% of these patients that are alive at six years are also disease free, suggesting that we are indeed making a dent on the natural history of the disease for these patients,” he said.

He also made a case for personalizing immunotherapy and suggested that CheckMate 227 could provide some guidance. “Ipilimumab/nivolumab – the CheckMate 227 regimen – appears to be particularly active in terms of inducing long-term, long-lasting responses and overall survival in patients harboring tumors that are negative for PD-L1,” he said.

Dr. Skoulidis also highlighted the 16% six-year overall survival among PD-L1 negative patients who received NIVO-IPI, calling it “impressive.” Of those who responded, 25% continued to respond at 6 years. “This is particularly notable in the subset of patients with squamous histology and lack of PD-L1 expression, where the six year overall survival rate with NIVO-IPI versus chemo was 18% versus 4%. So perhaps in patients with squamous histology and lack of PD-L1 expression, NIVO-IPI might represent a favorable regimen to improve long term outcomes,” said Dr. Skoulidis.

CheckMate 227 was funded by Bristol Myers Sqiubb. Dr. Peters has financial relationships with a wide range of pharmaceutical companies, including Bristol Myers Squibb. Dr. Skoulidis has financial relationships with Moderna, BioNTech, Amgen, Intellisphere, Navire, BeiGene, Medscape, Calithera Biosciences, Tango Therapeutics, Guardant Health, Novartis, AIMM Therapeutics, Mirati Therapeutics, Boehringer Ingelheim, Merck, and Pfizer.

After 6 years, previous tumor response, tumor burden reduction, and baseline health-related quality of life all correlated with overall survival, according to the latest analysis from the study.

“Patients treated with NIVO-IPI versus chemotherapy continue to derive long term durable efficacy benefit in CheckMate 227, regardless of PD-L1 expression. This represents the longest ever reported follow-up across phase three studies of frontline immunotherapy in patients with metastatic non–small cell lung cancer, and this further highlights the clinical benefit of frontline NIVO-IPI as a treatment in these patients with metastatic non–small cell lung cancer, regardless of the PD-L1 expression,” said Solange Peters, MD, PhD, during a presentation of the latest analysis at the annual World Conference on Lung Cancer. Dr. Peters is a professor of oncology at Lausanne (Switzerland) University Hospital.

The combination of nivolumab and ipilimumab has shown long-term survival benefit in other cancer types, including advanced melanoma, advanced renal cell carcinoma, and unresectable pleural mesothelioma.

The same session featured other studies demonstrating positive outcomes of immunotherapy in NSCLC. Serving as a discussant, Ferdinandos Skoulidis MD, PhD, commented, “I would argue that we are now at an inflection point where we can claim that we are altering the natural history of the disease for a subset of patients.” Dr. Skoulidis is an associate professor of thoracic oncology at the University of Texas MD Anderson Cancer Center.

CheckMate 227 enrolled patients with metastatic or recurrent NSCLC, excluding those with EGFR/ALK alterations. Patients with PD-L1 expression greater than or equal to 1% (PD-L1 positive, n = 1,189) were randomized to NIVO-IPI, NIVO, or chemotherapy. Patients with PD-L1 expression less than 1% (n = 550, PD-L1 negative) were randomized to NIVO-IPI, NIVO plus chemotherapy, or chemotherapy alone. The 5-year landmark analysis, which was published by the National Center for Biotechnology Information, showed overall survival rate of 24% among PD-L1 greater than or equal to 1% patients (PD-L1 positive) and 19% in PD-L1 less than 1% (PD-L1 negative) patients who received IPI-NIVO therapy, compared with 14% and 7%, respectively, in the chemotherapy only groups.

At WCLC, Dr. Peters presented data extending to 6 years of follow-up, as well as exploratory analyses. At 6 years of follow-up, in PD-L1 positive patients, 22% of the NIVO-IPI group remained alive, versus 13% of the chemotherapy group (hazard ratio, 0.78; 95% confidence interval, 0.67-0.91), while there was no significant improvement in OS for nivolumab alone, compared with chemotherapy. In the PD-L1 negative group, 16% were alive at 6 years in the IPI-NIVO group (HR, 0.65; 95% CI, 0.52-0.81), as were 10% in NIVO plus chemotherapy (HR, 0.79; 95% CI, 0.64-0.98) group, versus 5% in the chemotherapy group. The benefit of NIVO-IPI was significant in both squamous and non-squamous tumors for both PDL1-positive and PD-L1 negative patients.

At 6 years follow-up, 27% of PD-L1 positive patients who responded to NIVO-IPI remained in response, versus 22% in the NIVO group and 4% in the chemotherapy only group. Among PD-L1 negative patients, 25% of combination therapy responders remained in response at 6 years, while there were 10% still in response among the NIVO group, and none in the chemotherapy only group.
 

Exploratory analyses

Dr. Peters presented a slide showing tumor burden reductions occurring in responders. “What has to be concluded from this very interesting graph is that there are more, deeper responses in the NIVO-IPI versus chemotherapy. Very importantly, too, this is strongly correlated with survival. In both treatment arms, a high magnitude of tumor burden reduction is correlated with an improved survival,” said Dr. Peters. Specifically, among PD-L1 positive patients with more than 80% tumor reduction, survival was 59% at 6 years (95% CI, 44-71%). The figure was 68% in the NIVO only arm (95% CI, 47-82%), and 42% in the chemotherapy only arm (95% CI, 15-66%).

Among PD-L1 negative patients, “there are more, deeper responses in NIVO-IPI versus chemotherapy. That is very clear. And probably differently from the positive PD-L1 arm, the tumor burden reduction is correlated with survival but really only strongly observed in the NIVO-IPI arm,” said Dr. Peters. The figure was 20% in the nivolumab arm (95% CI, 3-48%) and 0% in the chemotherapy only arm (95% CI, not available). “So really something is correlating the tumor burden reduction with the outcome and specifically correlating it in the negative PD-L1 with the treatment of NIVO-IPI,” said Dr. Peters.

The researchers also noted longer progression-free survival and overall response rate in the NIVO-IPI group than the chemotherapy group in both PD-L1 positive and PD-L1 negative patients.

With respect to health-related quality of life, the researchers found a correlation between higher scores at baseline on the EQ-5D-3L scale and overall survival in the chemotherapy group (HR, 0.61; 95% CI, 0.51-0.74) and a trend in the NIVO-IPI group (HR, 0.83; 95% CI, 0.69-1.01). “So this baseline history, the quality of life, is correlated with the outcome regardless of the treatment you deliver,” said Dr. Peters.
 

Personalizing immunotherapy in NSCLC

In his comments, Dr. Skoulidis highlighted the length of responses. “Most importantly, approximately 50% of these patients that are alive at six years are also disease free, suggesting that we are indeed making a dent on the natural history of the disease for these patients,” he said.

He also made a case for personalizing immunotherapy and suggested that CheckMate 227 could provide some guidance. “Ipilimumab/nivolumab – the CheckMate 227 regimen – appears to be particularly active in terms of inducing long-term, long-lasting responses and overall survival in patients harboring tumors that are negative for PD-L1,” he said.

Dr. Skoulidis also highlighted the 16% six-year overall survival among PD-L1 negative patients who received NIVO-IPI, calling it “impressive.” Of those who responded, 25% continued to respond at 6 years. “This is particularly notable in the subset of patients with squamous histology and lack of PD-L1 expression, where the six year overall survival rate with NIVO-IPI versus chemo was 18% versus 4%. So perhaps in patients with squamous histology and lack of PD-L1 expression, NIVO-IPI might represent a favorable regimen to improve long term outcomes,” said Dr. Skoulidis.

CheckMate 227 was funded by Bristol Myers Sqiubb. Dr. Peters has financial relationships with a wide range of pharmaceutical companies, including Bristol Myers Squibb. Dr. Skoulidis has financial relationships with Moderna, BioNTech, Amgen, Intellisphere, Navire, BeiGene, Medscape, Calithera Biosciences, Tango Therapeutics, Guardant Health, Novartis, AIMM Therapeutics, Mirati Therapeutics, Boehringer Ingelheim, Merck, and Pfizer.

Long-term follow-up from the CheckMate 227 study has revealed lasting benefit from the combination of the CTLA-4 inhibitor ipilimumab (IPI) and the PD-1 inhibitor nivolumab (NIVO) in non-small cell lung cancer. After 6 years, previous tumor response, tumor burden reduction, and baseline health-related quality of life all correlated with overall survival, according to the latest analysis from the study.

“Patients treated with NIVO-IPI versus chemotherapy continue to derive long term durable efficacy benefit in CheckMate 227, regardless of PD-L1 expression.

The Food and Drug Administration on Sept. 15 approved the Janus kinase (JAK) inhibitor momelotinib (Ojjaara) for myelofibrosis patients with anemia, according to a press release from maker GSK.

Momelotinib is the fourth JAK inhibitor to be approved by the agency for myelofibrosis but the only one indicated for patients with hemoglobin levels below 10 g/dL.

It’s an important development because, while JAK inhibitors are standard treatment for myelofibrosis, those previously approved for the uncommon blood cancer can cause cytopenia, particularly anemia, which, ironically, is also a hallmark of myelofibrosis itself.

This issue makes using JAK inhibitors for myelofibrosis challenging, according to Anthony Hunter, MD, a myeloid malignancies specialist at Emory University, Atlanta, who spoke on the topic recently at the annual meeting of the Society of Hematologic Oncology in Houston. “Momelotinib is an important emerging agent for these more anemic patients.” Momelotinib has a spleen response comparable with ruxolitinib – the first JAK inhibitor approved for myelofibrosis in the United States – and significantly higher rates of transfusion independence, although lower rates of symptom control, he said.

In GSK’s press release, hematologist/oncologist Ruben Mesa, MD, executive director of Atrium Health Wake Forest Baptist Comprehensive Cancer Center, Winston-Salem, N.C., said that, “with momelotinib, we have the potential to establish a new standard of care for myelofibrosis patients with anemia.”

Momelotinib’s specific indication is for “the treatment of intermediate or high-risk myelofibrosis, including primary myelofibrosis or secondary myelofibrosis (post–polycythemia vera and post–essential thrombocythemia), in adults with anemia.”

The once-daily oral medication was approved based on two trials. One trial, MOMENTUM, showed statistically significant response with respect to constitutional symptoms, splenic response, and transfusion independence in anemic patients treated with momelotinib versus danazol.

An anemic subset of the SIMPLIFY-1 trial showed comparable spleen volume reduction versus ruxolitinib but a numerically lower symptom response rate.

The most common momelotinib adverse reactions in trials were thrombocytopenia, hemorrhage, bacterial infection, fatigue, dizziness, diarrhea, and nausea.

My young patient with type 1 diabetes (T1D) had her cell phone out to provide a share code for her Dexcom clarity app as she was checking into her visit. As my nurse was recording the code, the patient asked him, “Hey, can you add me on Snapchat?”

Her father scrolled through his own Facebook feed in the chair next to her, showing no concern that his daughter was looking to connect with an adult on a social media platform. Meanwhile, we were all grateful that the little girl, who had had a seizure due to hypoglycemia in her preschool and pre–continuous glucose monitoring (CGM) years, had access to the tools harnessed within the sparkly encased phone she held in her small hands. But did anyone in the room fully understand the potential dangers?

We are living in an exhilarating era of diabetes technology, a treatment environment that I couldn’t have dreamed of during my pediatric endocrinology fellowship. T1D is a volatile condition that changes day to day, especially in growing children. A short decade ago, the best CGM available was a bulky device on loan to patients for 3 days at a time. Information was later downloaded in-office to get a better idea of general glucose trends, if insurance would approve its use at all.

Now, we have a variety of very wearable and accurate disposable CGMs accessible to most patients. Every major insulin pump has available closed-loop capabilities. Some patients can dose from apps on their cell phones rather than juggle another device or draw attention to an insulin pump at the cafeteria table.

These developments have been game changers for children and teenagers with diabetes and for their families. When wondering whether an athlete’s dazed appearance on a soccer field was due to hypoglycemia, a parent no longer must demand that a coach pull the player – a quick glance at a smartphone app can verify the blood glucose and change rate. Children can use programs and search engines to quickly verify carbohydrate counts. Life360 and other tracking programs have increased parental feelings of security, especially with young drivers living with a chronic medical condition.

The inevitable outcome of this available technology is that children living with T1D are given cell phones far earlier than are their siblings or peers owing to “necessity.” Parents understandably want a means to stay in close contact with their children in case of a medical emergency. As a physician and mother of young children, I am thankful for the technology that keeps my patients safer and that allows them to fully participate in everything from sports to travel to an uninterrupted night’s sleep. But I am also growing more concerned that we have not completely counted the cost of early smartphone use in children.

Smartphone presence in classrooms empowers teachers, students, parents, and school nurses to be aware of glycemic trends and prevent hypoglycemic emergencies. Smartphones have also shown to be a major distraction in that setting, causing many schools to ban their use entirely. Video apps such as YouTube and TikTok can provide a wealth of support and medical information but may also open the door to misinformation and dangerous social contagion, particularly surrounding disordered eating. Informative podcasts such as The Juicebox Podcast and online forums provide incredible support for families, but the constant siren call of a phone in their pockets leads to distracted parents constantly tending to other conversations or responding to ever more demanding employers rather than focusing on face-to-face education sessions.

The Surgeon General recently released a report concerning social media use in children. This eye-opening report revealed that one-third of children admitted to using their cell phones “almost constantly.” Social media use is associated with higher rates of anxiety and depression, especially in teen girls. This is particularly concerning for children with T1D, who are more likely to suffer from these conditions.

Beyond mental health concerns, especially to developing brains, unfettered Internet use increases the risk that children are exposed to predators and harmful content. The online safety monitoring platform Bark shared data from its 2021 surveillance. Bark found that 72% of tweens and 85% of teens were involved in an online bullying situation. Sixty-nine percent of tweens and 91% of teens encountered nudity or sexual content. Ten percent of tweens and 21% of teens encountered predatory behavior.

These alarming finds mirror the prevalence suggested by conversations in my office. I hear reports of my patients sneaking out at night to meet adults they met through social media, having suicidal ideation and attempts after Internet bullying, and sharing earnest belief in bizarre conspiracy theories gleaned from online forums that lead to dangerous health care practices.

Furthermore, time is a finite resource. Teens who are spending an average of 3.5 hours daily on their devices are running out of time to play, study, and grow extracurricular interests. My friend who coaches high school baseball lamented recently the poor athleticism in his recent teams. He theorized that his players had spent their summers on tablets rather than playing catch or climbing trees. The resulting declines in exercise in young people only serve to worsen the childhood obesity epidemic.

What is a concerned parent to do? First, all phones have controls that allow parents to choose which apps are allowed and which are blocked. Caregivers must understand how various social media platforms work. Installing programs such as Bark provides an additional layer of monitoring, though these are no substitute for parental vigilance. Importantly, parents should talk to their children about their concerns regarding social media.

Sadly, I have often noticed that caregivers pity the extra hardships their children endure as the result of T1D and other chronic diseases. Being lax with rules to attempt to compensate for other suffering is far too tempting. The goal is for children and teens living with T1D to have a full and normal childhood, and unrestricted smartphone access and early social media use should not be the goal for any child. For every family, a media use plan is a smart approach. The American Academy of Pediatrics suggests several commonsense steps to use technology wisely, and parents often must address their own relationships with their devices to model healthy engagement.

As health care professionals, we owe it to our patients to discuss the ups and downs of technology with our patients. We can’t ostrich our way through this. We can point our patients and families to supportive groups such as Osprey (Old School Parents Raising Engaged Youth), founded by Ben and Erin Napier from the HGTV show Home Town along with my college friends Taylor and Dr. Catherine Sledge. Wait Until 8th provides information and motivation for parents to make wise choices regarding phone use for their children. The documentary Childhood 2.0 is another compelling resource developed by pediatric emergency physician Dr. Free Hess and her team that summarizes many of these concerns.

In another decade, many of these dangers will be far clearer. As ubiquitous as smartphone misuse is in our society, I remain hopeful that our society will change its behaviors. Just because “everyone else” allows an unhealthy relationship with technology doesn’t mean that we should for our children.

When I was a child, smoking was glamorized in movies and restaurants had dedicated smoking sections. After strong public policy efforts, many geared toward children, smoking is now almost unthinkable. My 8-year-old asked me lately whether a lady smoking a cigarette in the car next to us would have to go to jail. I chose a career in pediatrics because I am an optimist at my very core. We can’t ignore the dangers associated with the wide door opened by mobile devices. We can celebrate the benefits while clearly facing the pitfalls.

For every family, a media use plan is a smart approach. The American Academy of Pediatrics suggests several commonsense steps to use technology wisely, and parents often must address their own relationships with their devices to model healthy engagement.

As health care professionals, we owe it to our patients to discuss the ups and downs of technology with our patients. We can’t ostrich our way through this. We can point our patients and families to supportive groups such as Osprey (Old School Parents Raising Engaged Youth), founded by Ben and Erin Napier from the HGTV show Home Town along with my college friends Taylor and Dr. Catherine Sledge. Wait Until 8th provides information and motivation for parents to make wise choices regarding phone use for their children. The documentary Childhood 2.0 is another compelling resource developed by pediatric emergency physician Dr. Free Hess and her team that summarizes many of these concerns.

In another decade, many of these dangers will be far clearer. As ubiquitous as smartphone misuse is in our society, I remain hopeful that our society will change its behaviors. Just because “everyone else” allows an unhealthy relationship with technology doesn’t mean that we should for our children.

When I was a child, smoking was glamorized in movies and restaurants had dedicated smoking sections. After strong public policy efforts, many geared toward children, smoking is now almost unthinkable. My 8-year-old asked me lately whether a lady smoking a cigarette in the car next to us would have to go to jail. I chose a career in pediatrics because I am an optimist at my very core. We can’t ignore the dangers associated with the wide door opened by mobile devices. We can celebrate the benefits while clearly facing the pitfalls.

My young patient with type 1 diabetes (T1D) had her cell phone out to provide a share code for her Dexcom clarity app as she was checking into her visit. As my nurse was recording the code, the patient asked him, “Hey, can you add me on Snapchat?”

Her father scrolled through his own Facebook feed in the chair next to her, showing no concern that his daughter was looking to connect with an adult on a social media platform. Meanwhile, we were all grateful that the little girl, who had had a seizure due to hypoglycemia in her preschool and pre–continuous glucose monitoring (CGM) years, had access to the tools harnessed within the sparkly encased phone she held in her small hands. But did anyone in the room fully understand the potential dangers?

We are living in an exhilarating era of diabetes technology, a treatment environment that I couldn’t have dreamed of during my pediatric endocrinology fellowship. T1D is a volatile condition that changes day to day, especially in growing children. A short decade ago, the best CGM available was a bulky device on loan to patients for 3 days at a time. Information was later downloaded in-office to get a better idea of general glucose trends, if insurance would approve its use at all.

Now, we have a variety of very wearable and accurate disposable CGMs accessible to most patients. Every major insulin pump has available closed-loop capabilities. Some patients can dose from apps on their cell phones rather than juggle another device or draw attention to an insulin pump at the cafeteria table.

These developments have been game changers for children and teenagers with diabetes and for their families. When wondering whether an athlete’s dazed appearance on a soccer field was due to hypoglycemia, a parent no longer must demand that a coach pull the player – a quick glance at a smartphone app can verify the blood glucose and change rate. Children can use programs and search engines to quickly verify carbohydrate counts. Life360 and other tracking programs have increased parental feelings of security, especially with young drivers living with a chronic medical condition.

The inevitable outcome of this available technology is that children living with T1D are given cell phones far earlier than are their siblings or peers owing to “necessity.” Parents understandably want a means to stay in close contact with their children in case of a medical emergency. As a physician and mother of young children, I am thankful for the technology that keeps my patients safer and that allows them to fully participate in everything from sports to travel to an uninterrupted night’s sleep. But I am also growing more concerned that we have not completely counted the cost of early smartphone use in children.

Smartphone presence in classrooms empowers teachers, students, parents, and school nurses to be aware of glycemic trends and prevent hypoglycemic emergencies. Smartphones have also shown to be a major distraction in that setting, causing many schools to ban their use entirely. Video apps such as YouTube and TikTok can provide a wealth of support and medical information but may also open the door to misinformation and dangerous social contagion, particularly surrounding disordered eating. Informative podcasts such as The Juicebox Podcast and online forums provide incredible support for families, but the constant siren call of a phone in their pockets leads to distracted parents constantly tending to other conversations or responding to ever more demanding employers rather than focusing on face-to-face education sessions.

The Surgeon General recently released a report concerning social media use in children. This eye-opening report revealed that one-third of children admitted to using their cell phones “almost constantly.” Social media use is associated with higher rates of anxiety and depression, especially in teen girls. This is particularly concerning for children with T1D, who are more likely to suffer from these conditions.

Beyond mental health concerns, especially to developing brains, unfettered Internet use increases the risk that children are exposed to predators and harmful content. The online safety monitoring platform Bark shared data from its 2021 surveillance. Bark found that 72% of tweens and 85% of teens were involved in an online bullying situation. Sixty-nine percent of tweens and 91% of teens encountered nudity or sexual content. Ten percent of tweens and 21% of teens encountered predatory behavior.

These alarming finds mirror the prevalence suggested by conversations in my office. I hear reports of my patients sneaking out at night to meet adults they met through social media, having suicidal ideation and attempts after Internet bullying, and sharing earnest belief in bizarre conspiracy theories gleaned from online forums that lead to dangerous health care practices.

Furthermore, time is a finite resource. Teens who are spending an average of 3.5 hours daily on their devices are running out of time to play, study, and grow extracurricular interests. My friend who coaches high school baseball lamented recently the poor athleticism in his recent teams. He theorized that his players had spent their summers on tablets rather than playing catch or climbing trees. The resulting declines in exercise in young people only serve to worsen the childhood obesity epidemic.

What is a concerned parent to do? First, all phones have controls that allow parents to choose which apps are allowed and which are blocked. Caregivers must understand how various social media platforms work. Installing programs such as Bark provides an additional layer of monitoring, though these are no substitute for parental vigilance. Importantly, parents should talk to their children about their concerns regarding social media.

Sadly, I have often noticed that caregivers pity the extra hardships their children endure as the result of T1D and other chronic diseases. Being lax with rules to attempt to compensate for other suffering is far too tempting. The goal is for children and teens living with T1D to have a full and normal childhood, and unrestricted smartphone access and early social media use should not be the goal for any child. For every family, a media use plan is a smart approach. The American Academy of Pediatrics suggests several commonsense steps to use technology wisely, and parents often must address their own relationships with their devices to model healthy engagement.

Before the pandemic, most of the public probably had a fleeting and limited familiarity with lateral flow tests (LFTs), also known as rapid antigen tests. Perhaps they used, or awaited the results of, a lateral flow home pregnancy test, which detects human chorionic gonadotropin in urine.

Then came COVID-19, and the need for large-scale testing. By late 2022, more than 3 billion tests for SARS-CoV-2 had been done worldwide. Although testing with reverse-transcription polymerase chain reaction (PCR) is the gold standard for diagnosing COVID, LFTs made possible large-scale testing at low cost with rapid results.

As of Sept. 12, the Food and Drug Administration lists 32 rapid antigen tests with emergency use authorizations (EUAs) for home use.

Now, many experts conclude, it’s time to expand the role of LFTs so the technology can help detect a host of other diseases. In a Nature Reviews bioengineering report, global experts from the United States, the United Kingdom, and other countries pointed out that commercial LFTs are currently not available for four of the eight known priority diseases of epidemic potential: Crimean-Congo hemorrhagic fever, Middle East respiratory syndrome coronavirus, Nipah and other henipaviruses, and Rift Valley fever.

It is prime time, these experts and others contend, to build a global network of LFT research and development hubs to strengthen diagnostic capability.

Expansion should not only include more tests for more diseases, some experts say, but also make use of existing technology to provide “full-circle” care. After a rapid test, for instance, users could download a mobile phone app, transmit the results to their health care provider, and then set up an appointment if needed or get a prescribed medication at the pharmacy.
 

Medical community on board

Clinicians support increased availability of LFTs, said Eric J. Topol, MD, professor and executive vice president of Scripps Research, La Jolla, Calif.“Rapid antigen tests are critical, made a big difference in the pandemic, and will be used increasingly for many other applications in the years ahead,” Dr. Topol said in an email.

Physicians welcome their potential, agreed William Schaffner, MD, professor of preventive medicine and infectious disease specialist at Vanderbilt University Medical Center, Nashville, Tenn. At the start of the pandemic, when he was briefed about a lateral flow device in development, he said, “I was blown away by the technology, ease of use, rapidity of getting a result, its reasonable accuracy and its anticipated relatively low price.”

Clinicians would probably see many advantages to having more LFTs for more diseases, Dr. Schaffner said, because they are of use not only at home but also in doctors’ offices and in emergency departments. Their increased use “would help [people] make quick decisions about treatment, especially for flu and COVID.”
 

How LFTs work

LFTs are capable of targeting antigens, such as for the COVID tests, and antibodies such as IgG or IgM. The tests are also capable of detecting nucleic acids, although the availability of these tests is currently rare.

First, a sample from blood, urine, saliva or other bodily sources is placed onto a sample pad. It travels to a conjugate pad containing antibodies. If the target being looked for is present, the target and antibodies bind and, as the sample moves along to the test line, produces a positive result line along with the control line (to show that the test worked).
 

Global market outlook

By 2030, the lateral flow assays market is predicted to rise to $14.1 billion, according to a report issued in September by the firm Research and Markets. In 2022, the market was estimated at $9.4 billion, with $3.6 billion of that in the United States.

The report details the performances of 55 major competitors, such as Abbott Laboratories, Siemens, and QuidelOrtho, but smaller companies and start-ups are also involved in LFT development.
 

LFTs: Pros and cons

Although LFTs give rapid results, their accuracy is lower than that of PCR, especially the sensitivity. For COVID antigen LFTs, the sensitivity ranges from 34.1% to 88.1%, with an overall specificity of 99.6%, according to a Cochrane Review report. The analytical sensitivity performance of PCR testing for COVID is near 100%.

Everyone acknowledges the accuracy challenge of LFTs. The technologies “are generally thought to have limitations of detection that for some applications may present a challenge,” said Douglas C. Bryant, president and CEO of QuidelOrtho, San Diego, which counts the QuickVue rapid test for COVID detection among its products.

However, Mr. Bryant added, “as we saw during the pandemic, there was a place for more sensitive PCR-based technologies that are often run in a lab and there was a place for the use of rapid tests: The key is knowing the strengths and best use cases when applying the different technologies.”

One strength, he said, was that the tests “were shown to be highly effective at detecting active, infectious cases of SARS-CoV-2 and the rapid turnaround time allowed patients to isolate themselves from others quickly to help curb the spread of infection to others.” Another advantage was the ability to screen high-risk populations such as nursing homes to detect positive cases and help prevent outbreaks.

The pandemic familiarized people with the tests, said Jeremy Stackawitz, CEO of Senzo, a start-up in vitro diagnostics company developing an amplified LFT platform for rapid tests for flu, tuberculosis, COVID, and Clostridioides difficile. People liked using them. Physicians generally accepted them. It works great with tele-doc. It works great with personalized medicine.

Now, he said, people used to the COVID self-tests are asking: “Where is my strep test? Where is my sexual health test?”
 

FDA’s perspective on LFTs

The FDA has no one-size-fits-all standard for evaluating LFTs.

“LFTs are evaluated with respect to their individual indications and the pathway under which they are being reviewed,” said James McKinney, an FDA spokesperson. “A performance recommendation for one type of lateral flow test may not be appropriate for another.”

EUAs, such as those given for the COVID at-home tests, require different levels of evidence than traditional premarket review, he said, whether de novo marketing authorization, 510(k) premarket notification, or premarket approval. The EUAs are evaluated with a risk-benefit analysis to speed up the time it takes to make the devices available.

And, Mr. McKinney said, for some devices, the FDA provides recommendations on the expected performance through guidance documents. For instance, for rapid devices developed to detect influenza A virus antigen, the FDA recommends including enough sample to generate sensitivity of greater than 60% and testing at least 50 samples.
 

LFTs: The potential, the challenges

Mr. Stackawitz predicted that, as more LFT self-tests become available, more people will seek care, just as they did with the COVID rapid tests. A 22-year-old who thinks he has chlamydia may balk at going to a doctor right away. However, “if he can go buy a soda and a test at CVS, it’s different, it really is. With a little anonymity, people will seek care.”

He has a vision shared by other experts: That testing technology will evolve so that after getting the results at home, people would follow through by sending those results to their health care provider and obtaining needed care or medication. In his opinion, this is superior to the traditional way, which often involves visiting a doctor with symptoms, going for tests, waiting for results, and then beginning treatment.

“It would make more sense if you came in knowing your results,” Mr. Stackawitz said. “It’s a much smarter pathway, gives better outcomes for the patient, is much quicker and at much less cost. And it frees up time for doctors. I think most physicians would embrace that.”

Although rapid testing is gaining well-deserved recognition, funding is an issue, according to the Nature Reviews report. Those experts warned that “a reduction in funding for LFT research post COVID-19 may hamper efforts to capitalize on gains in decentralized testing, especially self-testing, which may be critical to address future pandemic threats.”

TOPLINE:

Patients with both systemic sclerosis (SSc) and systemic lupus erythematosus (SLE) are more likely to be female, Black, and diagnosed with limited cutaneous SSc.

METHODOLOGY:

• Researchers used the 2019 SLE classification criteria from the European Alliance of Associations for Rheumatology and American College of Rheumatology to identify patients with SSc who also met criteria for SLE at a single academic center.
• The study population included 402 adults with SSc.
• The researchers compared demographics, laboratory data, clinical features, and mortality between patients with SSc-SLE and patients with SSc only.

TAKEAWAY:

• Among the 402 patients with SSc who were analyzed, 40 (10%) met the 2019 EULAR/ACR Classification Criteria for SLE.
• Patients with both SSc and SLE were significantly more likely to be female and Black, which is consistent with previous studies; patients with both conditions also were more likely than those with SSc alone to have limited cutaneous SSc (75% vs. 52.2%; P = .006).
• The prevalence of anti-U1-RNP antibody positivity, a classic marker for mixed connective tissue disease, was 30% in SSc-SLE patients and 6.6% in those with SSc only (P < .001).
• Mortality was similar between the two groups, and similar rates were also seen between the two for severe SSc-related end-organ damage, including pulmonary fibrosis, pulmonary hypertension, and scleroderma renal crisis.

IN PRACTICE:

The results highlight the need for clinicians to recognize the SSc-SLE overlap syndrome and to watch for scleroderma organ involvement in patients with features of SLE, Raynaud syndrome, anti-U1-RNP antibody positivity, or an isolated nucleolar pattern of antinuclear antibodies.

The primary cohort was designed to compare Black to non-Black patients with SSc, and the process of matching these patients may have introduced unmeasured selection bias. Also, since the study was based on classification criteria and not diagnostic criteria, the overlapping patients may not reflect patients with true overlapping of both conditions.

DISCLOSURES:

No outside funding source was listed by the authors. The researchers report no relevant financial relationships.

TOPLINE:

Patients with both systemic sclerosis (SSc) and systemic lupus erythematosus (SLE) are more likely to be female, Black, and diagnosed with limited cutaneous SSc.

METHODOLOGY:

• Researchers used the 2019 SLE classification criteria from the European Alliance of Associations for Rheumatology and American College of Rheumatology to identify patients with SSc who also met criteria for SLE at a single academic center.
• The study population included 402 adults with SSc.
• The researchers compared demographics, laboratory data, clinical features, and mortality between patients with SSc-SLE and patients with SSc only.

TAKEAWAY:

• Among the 402 patients with SSc who were analyzed, 40 (10%) met the 2019 EULAR/ACR Classification Criteria for SLE.
• Patients with both SSc and SLE were significantly more likely to be female and Black, which is consistent with previous studies; patients with both conditions also were more likely than those with SSc alone to have limited cutaneous SSc (75% vs. 52.2%; P = .006).
• The prevalence of anti-U1-RNP antibody positivity, a classic marker for mixed connective tissue disease, was 30% in SSc-SLE patients and 6.6% in those with SSc only (P < .001).
• Mortality was similar between the two groups, and similar rates were also seen between the two for severe SSc-related end-organ damage, including pulmonary fibrosis, pulmonary hypertension, and scleroderma renal crisis.

IN PRACTICE:

The results highlight the need for clinicians to recognize the SSc-SLE overlap syndrome and to watch for scleroderma organ involvement in patients with features of SLE, Raynaud syndrome, anti-U1-RNP antibody positivity, or an isolated nucleolar pattern of antinuclear antibodies.

Currently, more than 3.8 million breast cancer survivors reside in the United States, reflecting high prevalence as well as cure rates for this common malignancy.

When over-the-counter measures including vaginal lubricants and moisturizers are not adequate, vaginal estrogen may be a highly effective treatment for genitourinary syndrome of menopause (GSM), a common condition associated with hypoestrogenism that impairs sexual function and quality of life.

Use of vaginal formulations does not result in systemic levels of estrogen above the normal postmenopausal range. Nonetheless, the U.S. Food and Drug Administration lists a history of breast cancer as a contraindication to the use of all systemic as well as vaginal estrogens.

In premenopausal women, chemotherapy for breast cancer often results in early menopause. Aromatase inhibitors, although effective in preventing recurrent disease in menopausal women, exacerbate GSM. These factors result in a high prevalence of GSM in breast cancer survivors.

Because the safety of vaginal estrogen in the setting of breast cancer is uncertain, investigators at Johns Hopkins conducted a cohort study using claims-based data from more than 200 million U.S. patients that identified women with GSM who had previously been diagnosed with breast cancer. Among some 42,000 women diagnosed with GSM after breast cancer, 5% had three or more prescriptions and were considered vaginal estrogen users.

No significant differences were noted in recurrence-free survival between the vaginal estrogen group and the no estrogen group. At 5 and 10 years of follow-up, use of vaginal estrogen was not associated with higher all-cause mortality. Among women with estrogen receptor–positive tumors, risk for breast cancer recurrence was similar between estrogen users and nonusers.

However, concomitant use of vaginal estrogen and aromatase inhibitors was associated with a higher risk for breast cancer recurrence than was use of vaginal estrogen alone.

Although this important study’s findings have the limitations characteristic of observational studies, its large size and careful analyses suggest that in selected well-counseled breast cancer survivors, off-label use of vaginal estrogen may safely improve their sexual function and quality of life.

TOPLINE:

The incidence of extra-articular manifestations of rheumatoid arthritis (ExRA) has declined over time, but the manifestations’ association with increased mortality risk has not changed.

METHODOLOGY:

• A retrospective, population-based cohort study that included 907 adults with incident RA diagnosed during 1985-1999 (n = 296) or 2000-2014 (n = 611) in Olmsted County, Minn.
• Researchers assessed the cumulative incidence of ExRA in groups from both time periods.
• Cox proportional hazard models were used to identify associations between mortality and ExRA.

TAKEAWAY:

• Patients with ExRA had double the risk for premature mortality compared with those without ExRA (hazard ratio, 2.0), with increased mortality for both severe and nonsevere cases of ExRA (HR, 3.05 and 1.83, respectively).
• The 10-year cumulative incidence of developing any ExRA decreased significantly between the 1985-1999 group and the 2000-2014 group (45.1% vs. 31.6%; P = .001).
• The incidence of subcutaneous rheumatoid nodules decreased significantly between the two time periods (30.9% vs. 15.8%, respectively; P < .001), as did the incidence of nonsevere ExRA (41.4% vs. 28.8%, respectively; P < .001).
• Rheumatoid nodules were associated with increased mortality risk, and rheumatoid factor positivity was the strongest risk factor for developing ExRA and rheumatoid nodules.

IN PRACTICE:

The results illustrate the need to recognize the increased mortality risk for patients with severe or nonsevere ExRA.

LIMITATIONS:

The single geographic region and demographics of the study limit its generalizability, and its interpretation is affected by a lack of data on disease activity and the impact of improved therapeutics and management strategies.

DISCLOSURES:

The study was supported by grants from the National Institute of Arthritis and Musculoskeletal and SkinDiseases, the National Institute on Aging, and the National Center for Advancing Translational Sciences. Dr. Kimbrough had no financial conflicts to disclose. Two coauthors reported financial relationships with one or more pharmaceutical companies.

Key clinical point: The incidence of rheumatoid arthritis (RA) during the pandemic period was significantly higher in individuals who did vs did not develop COVID-19, with patients age 51-60 years having the seemingly highest risk.

Major finding: The incidence rates of developing seropositive RA (incidence rate ratio [IRR] 1.60; 95% CI 1.16-2.22) and unspecified RA (IRR 2.93; 95% CI 2.04-4.19) during the pandemic period (2020-2022) were significantly higher in patients with vs without previous COVID-19, with the incidence rates being the highest in the age group of 51-60 years vs the age group of 18-30 years (hazard ratio 9.16; 95% CI 7.24-11.59).

Study details: This retrospective, population-based cohort study analyzed the data of 3,335,084 individuals from the COOSALUD EPS registry (Columbia).
