IVIG Prophylaxis in Multiple Myeloma Cuts Infections, Boosts Survival
Among 225 consecutive patients who received at least one treatment for relapsed and/or refractory multiple myeloma, those who received IVIG prophylaxis experienced a significantly longer duration of infection-free survival and an almost threefold longer median overall survival, compared with patients who did not receive IVIG prophylaxis.
IVIG supplementation has been shown to prevent severe infections in patients with multiple myeloma, but evidence on the best time to initiate IVIG prophylaxis among those receiving teclistamab remains less clear.
“Our institutional practice is to start IVIG about cycle 2 of therapy, which ended up being around 39 days,” but a key takeaway from the current findings is to “start IVIG within 30 days,” said lead investigator Heloise Cheruvalath, BA, a medical student at Medical College of Wisconsin, Milwaukee, who presented the findings.
The 225 patients included in the study had received at least one dose of standard-of-care teclistamab or an investigational B-cell maturation antigen (BCMA)–directed bispecific antibody (bsAb). IVIG was given as prophylaxis to 92 patients (41%) in the primary arm. The remaining 133 patients (59%) did not receive IVIG prophylaxis, but 29% received IVIG after a documented infection.
In total, there were 288 infections in 136 patients, and about 61% of infections required hospitalization. Median time to infection was 97 days, with the 12-month cumulative incidence of all-grade infections reaching 73% and the incidence of grade 3 or higher infections totaling 53%. Respiratory tract infections were the most common infection type, with COVID-19 accounting for 11% of cases, Cheruvalath noted.
Comparing patients who did and did not receive IVIG prophylaxis, median infection-free survival was significantly longer in the prophylaxis group — a median of 7.7 months vs 3 months — as was grade 3 or higher infection-free survival — a median of 14 months vs 7.5 months.
IVIG prophylaxis also led to a higher rate of 2-year progression free survival in the prophylaxis vs nonprophylaxis group — at 38% vs 32% — as well as longer median progression-free survival — at 15 months vs 8 months.
After multivariate analysis, IVIG prophylaxis was no longer significantly associated with improved progression-free survival.
However, median overall survival did remain significantly better in the IVIG prophylaxis than the nonprophylaxis group after multivariate analysis — 44 months vs 16 months. The presence of high-risk and extramedullary disease was independently associated with worse overall survival.
The effects of IVIG prophylaxis were stronger for bacterial infections at earlier (30 days or sooner) vs later (31 days or later) time points, but timing of IVIG therapy did not appear to affect the incidence of viral infections.
A study limitation was lack of randomization; IVIG prophylaxis was given at the physician’s discretion. In addition, multiple myeloma treatment was not standardized, with 15% of IVIG patients and 38% of non-IVIG patients receiving investigational BCMA bsAB.
“However, the majority of those who received primary IVIG prophylaxis were treated with standard-of-care teclistamab, making our results generalizable to current clinical practice,” Cheruvalath said.
Rahul Banerjee, MD, who was not involved with the research, noted he has already started providing routine IVIG prophylaxis based on earlier research from this group. “Before I did, my patients would often get very rare infections requiring protracted courses of antibiotics,” Banerjee, from Fred Hutch Cancer Center, University of Washington School of Medicine, Seattle, said in an interview. “Moving to IVIG before the infections start makes much more sense.”
Banerjee also commented that, in general, “the myeloma field has been moving from IV treatments to subcutaneous treatments to lower ‘time toxicity’ and IVIG is a notable exception to that trend, but perhaps it won’t be this way forever.”
Many patients with rheumatologic conditions receive subcutaneous immunoglobulin, in some cases, with kits they can self-administer at home, Banerjee said, and “I know some groups are starting to work on moving subcutaneous immunoglobulin to the oncologic setting.”
Funding was provided by the Advancing Healthier Wisconsin Endowment. Cheruvalath has reported no relevant disclosures. Banerjee has reported consulting for Adaptive Biotechnologies, Bristol Myers Squibb, Caribou Biosciences, Genentech, GSK, Johnson & Johnson/Janssen, Karyopharm, Legend Biotech, Pfizer, Sanofi, and SparkCures; and receiving research funding from AbbVie, Johnson & Johnson, Novartis, Pack Health, Prothena, and Sanofi.

FROM ASH 2024
LBCL: Bispecific Antibodies Fare Less Well in Real-World Analysis
In a presentation at the American Society of Hematology (ASH) 2024 Annual Meeting, researchers reported that of 172 patients treated with the drugs who had evaluable responses over a median follow-up of 5 months, median progression-free survival was 2.7 months (95% CI, 2.0-3.9) and median overall survival was 7.2 months (95% CI, 6.1–not reached).
It’s important to consider the real-world nature of the study’s patient population, said first author Taylor R. Brooks, MD, of Cleveland Clinic, Ohio, in an interview. “Compared to pivotal trials, our cohort was enriched for patients with high-risk features, with almost three quarters having some comorbidity that would’ve excluded them from one of the [earlier] studies.”
He added that “though individuals eligible to receive these medicines may be more sick with high-risk disease, a sizable fraction will respond, and some will maintain remissions.’”
According to Brooks, about one third of patients with diffuse LBCL relapse after standard front-line R-CHOP therapy. “The prognosis is poor for patients who are not candidates for aggressive salvage chemotherapy and for those who relapse after two or more lines,” Brooks said. “T cell–engaging bispecific antibodies have emerged as a promising option for patients with relapsed or refractory large B-cell lymphoma, given their favorable rates and duration of responses as well as their manageable rates of toxicities.”
The Food and Drug Administration (FDA) granted accelerated approval for epcoritamab and glofitamab in 2023.
“With increasing uptake into clinical practice following the FDA approvals, there is increasing interest in assessing the efficacy and safety of these drugs in real-world, nontrial settings,” Brooks said. “The goal of our study was to investigate outcomes and identify clinical factors associated with outcomes.”
The multicenter, retrospective, observational REALBiTE study tracked 209 patients with relapsed/refractory diffuse LBCL at 19 US centers (epcoritamab, n = 139; glofitamab, n = 70; median age at start of treatment, 67 years [58-76]; 62.2% male; 74.2% diffuse LBCL). The median number of lines of therapy was three (range, 1-12).
“Patients who received epcoritamab tended to be slightly older, were more likely to have a history of indolent non-Hodgkin lymphoma prior to their diagnosis of aggressive B-cell lymphoma and were more likely to have an elevated International Prognostic Index score at the start of bispecific therapy, suggesting that these patients may have been slightly older with higher-risk disease compared to those who received glofitamab,” Brooks said.
In total, 172 patients were response-evaluable. The overall response rate was 50.6% (complete response, 23.8%; partial response, 26.7%; stable disease, 5.8%; progressive disease, 43.6%).
The overall and complete response rates were “somewhat lower that what has been published in the pivotal trials of these medicines,” Brooks said. The low progression-free and overall survival rates “highlight the difficulty in managing this group of patients.”
Cytokine release syndrome (CRS) of any grade occurred in 39.2% of patients: 51% in the epcoritamab group and 28.6% in the glofitamab group. Grade ≥3 CRS occurred in 4.3% of patients, who were all taking epcoritamab.
“For epcoritamab, CRS was almost entirely of low grade, and most CRS events occurred around administration of the first full dose of the drug on day 15,” Brooks said. “Similarly, the CRS events for glofitamab were mostly of low grade, though events were observed to occur throughout the step-up dosing. Tocilizumab was administered in about one fifth of the patients.”
In addition, Brooks said, “we found that, among the 19 individuals with paired biopsy samples before and after bispecific therapy, nearly all — 89% — were found to have lost CD20 expression. We expected some patients to experience loss of this important target, but the rate at which we found this to be the case was surprisingly high.”
Brooks added that “clinicians should be acquainted with CRS, ICANS [immune effector cell-associated neurotoxicity syndrome], and mitigation strategies if they are prescribing these medicines. Appropriate and timely management using tocilizumab, steroids, and other adjunctive measures can effectively manage these complications and hopefully allow for the continued delivery of therapy.”
In an interview, Matthew Lunning, DO, associate professor at the University of Nebraska Medical Center/Fred & Pamela Buffett Cancer Center, Omaha, who didn’t take part in the new study, said the findings aren’t bad news. Instead, they’re “practical news,” because they offer insight into how the drugs work.
“The big lesson from this and other trials is the importance of assessing for CD20 expression prior to taking a bispecific off the shelf, “ he said. “These are learnings that often come after approval.”
He added that it’s clear that, “in more heavily pretreated patients, more disease led to less optimal results and higher risk for toxicities.”
Lunning also noted that both epcoritamab and glofitamab “entered into a crowded and chaotic relapsed/refractory LBCL space based high complete response rates with the opportunity for durability in those complete responses.”
Academic institutions were especially interested, as they can manage CRS and ICANS, but “significantly less enthusiasm has been seen in community practices that expect CRS/ICANS to be in the rear-view mirror if they are going to deliver any bispecific,” he said. “It is not that they don’t have the clinical acumen to manage CRS/ICANS. I believe it is the perception of the lack of supportive infrastructure necessary to manage these toxicities.”
There was no study funding. Brooks has reported no disclosures. Other authors have reported various disclosures including relationships with Novartis, AbbVie, Genentech, Genmab, Biogen, Amgen, and others. Lunning has disclosed ties with AbbVie, Genmab, Kite, Bristol-Myers Squibb, Regeneron, and ADC Therapeutics.

ASH 2024: New Leukemia Txs, Fewer Blood Clots With GLP-1 Rxs
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.
A 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.

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.
A 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.

Human Milk Boosts Intestinal Growth, Immune Health of Fetal Organoids
These findings suggest an important role for human milk in supporting intestinal health, and may inform strategies for reducing the risk of necrotizing enterocolitis (NEC) in preterm infants, lead author Lauren Smith, MD, of Yale School of Medicine, New Haven, Connecticut, and colleagues, reported.
“Compelling evidence has revealed that the largest risk factor for NEC apart from prematurity is formula feeding, while conversely, parental milk (PM) confers protection, with a 6- to 10-fold lower incidence of NEC among PM-fed infants compared to formula,” the investigators wrote in Gastro Hep Advances. “It is unknown whether this is due to the many known protective factors in PM or as a result of an injurious component present in formula or a combination of both.”
To learn more, the investigators studied organoids cultured in a three-dimensional matrix and exposed to one of four dietary conditions: PM, donor human milk (DHM), standard formula (SF), or extensively hydrolyzed formula (HF). Organoids were grown in growth media supplemented with these diets for 5 days, followed by differentiation media for an additional 5 days. Growth, differentiation, and immune-related factors were analyzed using advanced imaging, RNA sequencing, and cytokine profiling.
The results demonstrated that human milk–fed organoids significantly outperformed formula-fed organoids in several measures. By the fifth day of growth media exposure, organoids supplemented with PM or DHM were larger and exhibited higher rates of proliferation, as evidenced by Ki67 staining. Organoids exposed to SF were the smallest and had the lowest proliferation and highest levels of apoptosis, while HF-fed organoids showed intermediate growth performance.
During the differentiation phase, organoids exposed to human milk developed more complex structures, forming buds with greater length and diameter compared to formula-fed organoids. PM was particularly effective, though DHM also promoted substantial differentiation. RNA sequencing revealed that organoids cultured with human milk upregulated genes involved in fatty acid metabolism and Wnt signaling, which are critical for cellular energy production and epithelial proliferation. In contrast, formula-fed organoids exhibited downregulation of cell-cycle-promoting genes and showed an inflammatory gene signature.
Cytokine profiling further underscored the benefits of human milk. Organoids exposed to PM and DHM secreted higher levels of immune-regulating cytokines, such as thymic stromal lymphopoietin (TSLP) and macrophage colony-stimulating factor (M-CSF). In contrast, formula-fed organoids produced lower levels of these beneficial cytokines and higher levels of pro-inflammatory markers, including interleukin-18 (IL-18).
These findings suggest that human milk supports intestinal growth, differentiation, and immune regulation in ways that formula does not, and the investigators emphasized the importance of identifying specific bioactive factors in human milk.
“If the factors responsible for this effect can be identified, there could be significant clinical value in supplementing these components in DHM and formula to help prevent NEC and foster normal intestinal development in preterm infants,” they concluded.
Future research will aim to isolate and supplement key components of human milk to enhance the nutritional and protective value of donor milk and formula. In addition, the investigators noted the need to explore potential sex-based differences in intestinal development, as the current study used only male-derived samples.The research was supported by the Yale School of Medicine Medical Student Research Fellowship. The investigators disclosed no conflicts of interest.

Biomarkers Predict Villous Atrophy in Potential Celiac Disease Patients
according to investigators.
Given that PCD patients present with positive serology and intact duodenal architecture, these findings may provide a much-needed tool for identifying patients who are more likely to benefit from early dietary interventions, lead author Renata Auricchio, MD, PhD, of the University of Naples Federico II, Italy, and colleagues reported.
“PCD offers the unique opportunity to observe the progression of gluten-induced tissue damage in celiac disease,” the investigators wrote in Gastroenterology. “These patients recognize gluten and produce specific autoantibodies, but have not developed intestinal damage.”
The study included 31 children with asymptomatic PCD who were eating a gluten-containing diet. Serum samples from each child were analyzed for the relative abundance of 92 inflammation-linked proteins using a proximity extension immunoassay. Statistical analyses, including partial least squares discriminant and linear discriminant analyses, were then applied to identify which proteins were associated with the development of VA.
After a mean follow-up period of 5.85 years, 14 participants developed VA (ie, celiac disease), while the remaining 17 remained asymptomatic.
Panel analysis revealed that specific inflammatory proteins, including interleukin (IL)–20, IL-2, sirtuin 2 (SIRT2), leukemia inhibitory factor (LIF), IL-22 receptor subunit a1, cystatin D (CST5), IL-17 receptor A, IL-15 receptor subunit a (RA), CUB domain–containing protein 1 (CDCP1), and IL-14, were 1.23- to 1.76-fold higher in children who developed VA. Among these, seven proteins — CDCP1, IL-2, LIF, IL10RA, SIRT2, CST5, and IL-4 — were able to significantly distinguish between symptomatic and asymptomatic cases in a linear discriminant model. This panel of seven proteins achieved a predictive accuracy of 96.8% in identifying children at risk of VA.
Additionally, bioinformatics pathway analysis confirmed that the broader set of proteins is involved in the positive regulation of JAK-STAT signaling (involving IL-22 receptor subunit a1, IL-4, IL-20, IL10RA, LIF, and IL-2), inflammatory responses (IL-4, IL-20, LIF, and IL-2), and processes such as tyrosine phosphorylation, leukocyte differentiation, IgG isotype switching, and protein phosphorylation regulation. These findings suggest that gluten-induced inflammation may already be active in early stages of the disease, including the initial phases of leukocyte differentiation, according to the investigators.
“Over a long follow-up on a gluten-containing diet, only 40% of these patients progressed to VA,” Dr. Auricchio and colleagues wrote. “Notably, 25%-30% of children with PCD even stop producing anti–tissue transglutaminase antibodies, and the others keep on producing autoantibodies but preserve a normal intestinal mucosa. Considering these data, the decision to address a patient with PCD on a gluten-free diet at time of diagnosis is quite critical.”
The researchers noted that this new model, with accuracy exceeding 95%, is well suited for routine use because of its practicality and reliability.
“Our previous model, based mainly on small intestinal mucosa features, moved a step toward the prediction of outcome but still required a mucosal biopsy, and the accuracy of prediction was not greater than 80%, which is somewhat uncertain for a lifelong clinical decision,” they wrote. In contrast, the present model “appears to be sufficient to immediately suggest a gluten-free diet in children with PCD, who are almost certainly committed to developing VA.”
The investigators called for long-term studies to validate their findings in other cohorts, including adult populations.This study was supported by the TIMID project and Inflammation in Human Early Life: Targeting Impacts on Life Course Health (INITIALISE) by the Horizon Europe Program of the European Union. The investigators disclosed no conflicts of interest.
Patients with positive celiac serologies but normal villous architecture on biopsy are considered to have potential celiac disease (PCD). While the prevalence of PCD is not well-established, it is estimated to be around 1%. This study by Auricchio and colleagues investigates seven serum proteomic biomarkers that could help predict whether asymptomatic patients with PCD are at risk of developing villous atrophy (VA).
The study also identifies specific inflammatory proteins present in PCD patients who are likely to develop VA. These biomarkers provide valuable insights into the pathogenesis of celiac disease and the development of VA in genetically predisposed individuals.
As celiac disease is increasingly diagnosed without biopsies, serum proteomic biomarkers could be crucial in identifying patients who may benefit from starting a gluten-free diet (GFD) earlier, potentially preventing complications. According to the European Society of Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) guidelines, children can be diagnosed with celiac disease if their tissue transglutaminase IgA level is 10 times the upper limit of normal, confirmed by a positive endomysial antibody test. However, this approach may lead to many patients committing to a lifelong GFD despite having only PCD, as biopsies may not have been performed. In this study, 60% of patients with PCD did not progress to VA, suggesting that biomarkers could help prevent unnecessary long-term GFD commitments.

Given that PCD patients present with positive serology and intact duodenal architecture, these findings may provide a much-needed tool for identifying patients who are more likely to benefit from early dietary interventions, lead author Renata Auricchio, MD, PhD, of the University of Naples Federico II, Italy, and colleagues reported.
“PCD offers the unique opportunity to observe the progression of gluten-induced tissue damage in celiac disease,” the investigators wrote in Gastroenterology. “These patients recognize gluten and produce specific autoantibodies, but have not developed intestinal damage.”
The study included 31 children with asymptomatic PCD who were eating a gluten-containing diet. Serum samples from each child were analyzed for the relative abundance of 92 inflammation-linked proteins using a proximity extension immunoassay. Statistical analyses, including partial least squares discriminant and linear discriminant analyses, were then applied to identify which proteins were associated with the development of VA.
After a mean follow-up period of 5.85 years, 14 participants developed VA (ie, celiac disease), while the remaining 17 remained asymptomatic.
Panel analysis revealed that specific inflammatory proteins, including interleukin (IL)–20, IL-2, sirtuin 2 (SIRT2), leukemia inhibitory factor (LIF), IL-22 receptor subunit a1, cystatin D (CST5), IL-17 receptor A, IL-15 receptor subunit a (RA), CUB domain–containing protein 1 (CDCP1), and IL-14, were 1.23- to 1.76-fold higher in children who developed VA. Among these, seven proteins — CDCP1, IL-2, LIF, IL10RA, SIRT2, CST5, and IL-4 — were able to significantly distinguish between symptomatic and asymptomatic cases in a linear discriminant model. This panel of seven proteins achieved a predictive accuracy of 96.8% in identifying children at risk of VA.
Additionally, bioinformatics pathway analysis confirmed that the broader set of proteins is involved in the positive regulation of JAK-STAT signaling (involving IL-22 receptor subunit a1, IL-4, IL-20, IL10RA, LIF, and IL-2), inflammatory responses (IL-4, IL-20, LIF, and IL-2), and processes such as tyrosine phosphorylation, leukocyte differentiation, IgG isotype switching, and protein phosphorylation regulation. These findings suggest that gluten-induced inflammation may already be active in early stages of the disease, including the initial phases of leukocyte differentiation, according to the investigators.
“Over a long follow-up on a gluten-containing diet, only 40% of these patients progressed to VA,” Dr. Auricchio and colleagues wrote. “Notably, 25%-30% of children with PCD even stop producing anti–tissue transglutaminase antibodies, and the others keep on producing autoantibodies but preserve a normal intestinal mucosa. Considering these data, the decision to address a patient with PCD on a gluten-free diet at time of diagnosis is quite critical.”
The researchers noted that this new model, with accuracy exceeding 95%, is well suited for routine use because of its practicality and reliability.
“Our previous model, based mainly on small intestinal mucosa features, moved a step toward the prediction of outcome but still required a mucosal biopsy, and the accuracy of prediction was not greater than 80%, which is somewhat uncertain for a lifelong clinical decision,” they wrote. In contrast, the present model “appears to be sufficient to immediately suggest a gluten-free diet in children with PCD, who are almost certainly committed to developing VA.”
The investigators called for long-term studies to validate their findings in other cohorts, including adult populations.This study was supported by the TIMID project and Inflammation in Human Early Life: Targeting Impacts on Life Course Health (INITIALISE) by the Horizon Europe Program of the European Union. The investigators disclosed no conflicts of interest.

Intratumoral Dendritic Cell Therapy Shows Promise in Early-Stage ERBB2-Positive Breast Cancer
TOPLINE:
The higher dose (100 million cells) shows enhanced immune effector recruitment and significant tumor regression before chemotherapy initiation.
METHODOLOGY:
- ERBB2-positive breast cancer survival has improved with anti-ERBB2 antibodies trastuzumab and pertuzumab, but for a pathologic complete response, chemotherapy remains necessary, which comes with significant toxic effects.
- A phase 1, nonrandomized clinical trial enrolled 12 patients with early-stage ERBB2-positive breast cancer in Tampa, Florida, from October 2021 to October 2022.
- Participants received intratumoral (IT) cDC1 injections weekly for 6 weeks at two dose levels (50 million cells for dose level 1 and 100 million cells for dose level 2), with six patients in each group.
- Starting from day 1 of the cDC1 injections, treatment included trastuzumab (8-mg/kg loading dose, then 6 mg/kg) and pertuzumab (840-mg loading dose, then 420 mg) administered intravenously every 3 weeks for six cycles, followed by paclitaxel (80 mg/m2) weekly for 12 weeks and surgery with lumpectomy or mastectomy.
- Primary outcomes measured safety and immune response of increasing doses of cDC1 combined with anti-ERBB2 antibodies before neoadjuvant chemotherapy; secondary outcomes assessed antitumor efficacy through breast MRI and residual cancer burden at surgery.
TAKEAWAY:
- IT delivery of ERBB2 cDC1 was safe and not associated with any dose-limiting toxic effects. The most frequent adverse events attributed to cDC1 were grade 1-2 chills (50%), fatigue (41.7%), headache (33%), and injection-site reactions (33%).
- Dose level 2 showed enhanced recruitment of adaptive CD3, CD4, and CD8 T cells and B cells within the tumor microenvironment (TME), along with increased innate gamma delta T cells and natural killer T cells.
- Breast MRI revealed nine objective responses, including six partial responses and three complete responses, with three cases of stable disease.
- Following surgery, 7 of 12 patients (58%) achieved a pathologic complete response, including all 3 hormone receptor–negative patients and 4 of the 9 hormone receptor–positive patients.
IN PRACTICE:
“Overall, the clinical data shown here demonstrate the effects of combining ERBB2 antibodies with IT [intratumoral] delivery of targeted cDC1 to enhance immune cell infiltration within the TME [tumor microenvironment] and subsequently induce tumor regression before chemotherapy,” wrote the authors, who noted they will be testing the higher dose for an ongoing phase 2 trial with an additional 41 patients.
SOURCE:
The study was led by Hyo S. Han, MD, of H. Lee Moffitt Cancer Center and Research Institute in Tampa, Florida. It was published online on December 5, 2024, in JAMA Oncology.
LIMITATIONS:
Because only two dose levels of cDC1 were tested, it remains unclear whether higher doses or different administration schedules could further enhance immune response. Additionally, the nonrandomized design prevents definitive conclusions about whether the clinical benefits were solely from the anti-ERBB2 antibodies. The small sample size also makes it difficult to determine if the pathologic complete responses were primarily due to the 12 weeks of trastuzumab/pertuzumab/paclitaxel treatment.
DISCLOSURES:
This study was funded by the Moffitt Breast Cancer Research Fund, Shula Fund, and Pennies in Action. Several authors reported research support and personal and consulting fees from US funding agencies and multiple pharmaceutical companies outside of the submitted work, as well as related intellectual property and patents.

FDA Approves Durvalumab for Limited-Stage SCLC
The Food and Drug Administration approval makes the monoclonal antibody — which is already approved for multiple tumor types — the first immunotherapy regimen approved in this setting, AstraZeneca noted in a press release.
“Durvalumab is the first and only systemic treatment following curative-intent, platinum-based chemoradiotherapy to show improved survival for patients with this aggressive form of lung cancer,” international coordinating investigator on the trial, Suresh Senan, PhD, stated in the press release. “This finding represents the first advance for this disease in 4 decades.”
Approval, which followed Priority Review and Breakthrough Therapy Designation, was based on findings from the phase 3 ADRIATIC trial showing a 27% reduction in the risk for death with durvalumab vs placebo.
Findings from the trial were reported during a plenary session at the 2024 American Society of Clinical Oncology conference, and subsequently published in The New England Journal of Medicine.
In 730 patients with LS-SCLC who were randomized 1:1:1 to receive single-agent durvalumab, durvalumab in combination with tremelimumab, or placebo, overall survival (OS) and progression-free survival (PFS) were significantly improved with durvalumab alone vs placebo (hazard ratio, 0.73 and 0.76, for OS and PFS, respectively). Median OS was 55.9 months vs 33.4 months with durvalumab vs placebo, and PFS was 16.6 vs 9.2 months, respectively.
Senan, a professor of clinical experimental radiotherapy at the Amsterdam University Medical Center in the Netherlands, noted in the press release that 57% of patients were still alive at 3 years after being treated with durvalumab, which underscores the practice-changing potential of this medicine in this setting.
“This new treatment option is a game changer for patients with limited-stage small cell lung cancer, a disease known for its high rate of recurrence,” Dusty Donaldson, founder and executive director of the nonprofit advocacy organization LiveLung, stated in the release. “Historically, more often than not, clinical trials to identify new treatment options for this type of cancer have failed to show benefit. We are therefore so excited that many more people will now have the opportunity to access this immunotherapy treatment that holds the potential to significantly improve outcomes.”
Adverse reactions occurring in at least 20% of patients in the ADRIATIC trial included pneumonitis or radiation pneumonitis and fatigue.
The recommended durvalumab dose, according to prescribing information, is 1500 mg every 4 weeks for patients weighing at least 30 kg and 20 mg/kg every 4 weeks for those weighing less than 30 kg, until disease progression or unacceptable toxicity or a maximum of 24 months.

Nonmelanoma Skin Cancer Risk May Be Reduced in Patients on PCSK9 Inhibitors
TOPLINE:
Proprotein convertase subtilisin/kexin type 9 ( those older than 65 years, and those with immunosuppression.
METHODOLOGY:
- To evaluate the risk for NMSC — basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) — in patients with ASCVD on PCSK9 inhibitors, researchers analyzed data from the US Collaborative Network in the TriNetX database of adults aged ≥ 40 years with ASCVD who received statin therapy between 2016 and 2022.
- A total of 73,636 patients were included, divided equally between those receiving a PCSK9 inhibitor (evolocumab, alirocumab, or inclisiran) plus statin therapy and the control group (those on statin therapy only).
- The analysis used propensity score matching for head-to-head comparisons, with hazard ratios (HRs) estimated using Cox proportional hazard models.
- Stratified analyses examined outcomes by age, sex, Fitzpatrick skin type, and immune status. (Immunosuppressed patients were those treated with immunosuppressants for more than 90 days in the year before the index date — the date when exposed patients were first prescribed a PCSK9 inhibitor, which was also index date for matched patients in the statin-only group.)
TAKEAWAY:
- Patients with ASCVD in the PCSK9 group showed significantly lower risks for NMSC (HR, 0.78; 95% CI, 0.71-0.87), BCC (HR, 0.78; 95% CI, 0.69-0.89), and SCC (HR, 0.79; 95% CI, 0.67-0.93) than control individuals on a statin only (P < .001 for all three).
- Both evolocumab and alirocumab demonstrated similar protective effects against the development of NMSC.
- The reduced risk for NMSC was particularly notable among patients aged 65-79 years (HR, 0.75; 95% CI, 0.66-0.86) and those aged ≥ 80 years (HR, 0.74; 95% CI, 0.60-0.91).
- Men showed a more pronounced reduction in the risk for NMSC (HR, 0.73; 95% CI, 0.64-0.83) than women (HR, 0.93; 95% CI, 0.78-1.11). The effect on lowering NMSC risk was also evident among immunosuppressed patients in the PCSK9 group (HR, 0.68; 95% CI, 0.60-0.75).
IN PRACTICE:
“The findings suggest the promising pleiotropic effect of PCSK9 inhibitors on the chemoprevention of NMSC,” the study authors wrote. Referring to previous studies that “provided mechanistic clues to our findings,” they added that “further studies are required to investigate the underlying mechanisms and establish causality.”
SOURCE:
The study was led by Cheng-Yuan Li, Taipei Veterans General Hospital, Taipei, Taiwan, and was published online in The British Journal of Dermatology.
LIMITATIONS:
Electronic health records lack information on sun protection habits, family history of skin cancer, diet, body mass index, and air pollution exposure, risk factors for NMSC. The study also lacked detailed information on enrollees’ lipid profiles and was focused mostly on patients in the United States, limiting the generalizability of the findings to other regions.
DISCLOSURES:
The study was supported by grants from Taipei Veterans General Hospital and the Ministry of Science and Technology, Taiwan. The authors reported no conflicts of interest.

Lung CT Can Detect Coronary Artery Disease, Predict Death
“The high prevalence of asymptomatic coronary artery disease (83%) was surprising, as was the prevalence of extensive CAC (30%),” principal investigator Gary Small, MBChB, PhD, a cardiologist at the University of Ottawa Heart Institute in Ontario, Canada, said in an interview.
“The size of effect was also surprising, as was the persistence of the effect even in the presence of elevated mortality risk from other causes,” he said. “Extensive coronary disease was associated with a twofold increase in risk for death or cardiovascular events over 4 years of follow-up,” even after adjustment for risk for death from cancer and other comorbidities such as chronic obstructive pulmonary disease.
“CAC as reported on chest CT exams is often ignored and not factored into clinical practice,” he noted. “The presence of CAC, however, provides a very real and very personal perspective on an individual’s cardiovascular risk. It is a true example of personalized medicine.”
The study was published online in The Canadian Medical Association Journal.
Potential Risk Reduction
In March 2017, Ontario Health launched a pilot low-dose CT lung cancer screening program for high-risk individuals between the ages of 55 and 74 years, Small explained. As CAC, a marker of coronary artery disease, is seen easily during such a scan, the researchers analyzed the lung CTs to determine the prevalence of coronary artery disease and whether CAC was associated with increased risk.
The team quantified CAC using an estimated Agatston score and identified the composite primary outcome of all-cause death and cardiovascular events using linked electronic medical record data from Ottawa Hospital up to December 2023. Among the 1486 people who underwent screening (mean age, 66 years; 52% men; 68% current smokers), CAC was detected in 1232 (82.9%). CAC was mild to moderate in 793 participants (53.4%) and extensive in 439 (29.5%). No CAC was detected in 254 (17.1%) participants.
At follow-up, 78 participants (5.2%) experienced the primary composite outcome, including 39 (8.9%) with extensive CAC, 32 (4.0%) with mild to moderate CAC, and 7 (2.8%) with no CAC.
A total of 49 deaths occurred, including 16 cardiovascular deaths and 19 cancer deaths, of which 10 were from lung cancer. Cardiovascular events included sudden cardiac death (eight participants), fatal stroke (six participants), and one each from heart failure and peripheral vascular disease.
On multivariable analysis, extensive CAC was associated with the composite primary outcome (adjusted hazard ratio [aHR], 2.13), all-cause mortality (aHR, 2.39), and cardiovascular events (aHR, 2.06).
Extensive CAC remained predictive of cardiovascular events even after adjustment for noncardiovascular death as a competing risk (HR, 2.05).
“Our data highlight to lung cancer screening professionals the prevalence of this silent risk factor and re-emphasize the importance of this finding [ie, CAC] as an opportunity for risk reduction,” Small said.
“In terms of next steps, the journey toward cardiovascular risk reduction begins with a clear report of CAC on the lung cancer screening record,” he noted. “Following this step, professionals involved in the lung cancer screening program might consider a local management pathway to ensure that this opportunity for health improvement is not lost or ignored. Preventive medicine of this type would typically involve primary care.”
Managing Other Findings
Commenting on the study, Anna Bader, MD, assistant professor of radiology and biomedical imaging at the Yale School of Medicine in New Haven, Connecticut, said that “low-dose CT for lung cancer screening offers valuable insights beyond nodule detection, with CAC being among the most significant incidental findings.”
However, she added, a “robust mechanism” to effectively manage other findings — such as thoracic aortic disease, low bone density, and abnormalities in the thyroid or upper abdominal organs — without overdiagnosis, is needed. A mechanism also is needed to notify cardiologists or primary care providers about severe CAC findings.
Challenges that need to be overcome before such mechanisms can be put in place, she said, “include ensuring standardized CAC reporting, avoiding overburdening healthcare providers, mitigating the risk of excessive downstream testing, and ensuring equitable access to follow-up care for underserved and rural communities.”
Providers involved in lung cancer screening “must be trained to recognize the importance of CAC findings and act upon them,” she added. “Awareness campaigns or continuing medical education modules could address this.”
Multidisciplinary lung cancer screening programs can help with patient education, she noted. “Clear communication about potential findings, including the significance of incidental CAC, should be prioritized and addressed proactively, ideally before the exam, to enhance patient understanding and engagement.”
Matthew Tomey, MD, assistant professor of medicine at the Icahn School of Medicine at Mount Sinai in New York City, said that, “as a practicing cardiologist, I find it very helpful to look at my patients’ recent or past CT scans to look for vascular calcification. Whether or not a scan is specifically protocoled as a cardiac study, we can often appreciate vascular calcification when it is present. I would encourage every physician involved in helping their patients to prevent heart disease to take advantage of looking at any prior CT scans for evidence of vascular calcification.
“Systems of care to facilitate recognition of patients with incidentally discovered vascular calcification would be welcome and, on a large scale, could help prevent cardiovascular events,” he noted. “Such a system might involve facilitating referral to a prevention specialist. It could involve evidence-based guidance for referring physicians who ordered scans.”
Like Bader, he noted the importance of patient education, adding that it could be quite powerful. “We should be doing more to empower our patients to understand the findings of their imaging and to give them actionable, evidence-based guidance on how they can promote their own cardiovascular health,” he concluded.
No funding for the study was reported. Small reported receiving a research grant for amyloid research from Pfizer and honoraria from Pfizer and Alnylam (all paid to the institution, outside the submitted work). Bader and Tomey declared no relevant conflicts.

Internet Use May Boost Mental Health in Later Life
TOPLINE:
and better self-reported health among adults aged 50 years or older across 23 countries than nonuse, a new cohort study suggests.
METHODOLOGY:
- Data were examined for more than 87,000 adults aged 50 years or older across 23 countries and from six aging cohorts.
- Researchers examined the potential association between internet use and mental health outcomes, including depressive symptoms, life satisfaction, and self-reported health.
- Polygenic scores were used for subset analysis to stratify participants from England and the United States according to their genetic risk for depression.
- Participants were followed up for a median of 6 years.
TAKEAWAY:
- Internet use was linked to consistent benefits across countries, including lower depressive symptoms (pooled average marginal effect [AME], –0.09; 95% CI, –0.12 to –0.07), higher life satisfaction (pooled AME, 0.07; 95% CI, 0.05-0.10), and better self-reported health (pooled AME, 0.15; 95% CI, 0.12-0.17).
- Frequent internet users showed better mental health outcomes than nonusers, and daily internet users showed significant improvements in depressive symptoms and self-reported health in England and the United States.
- Each additional wave of internet use was associated with reduced depressive symptoms (pooled AME, –0.06; 95% CI, –0.09 to –0.04) and improved life satisfaction (pooled AME, 0.05; 95% CI, 0.03-0.07).
- Benefits of internet use were observed across all genetic risk categories for depression in England and the United States, suggesting potential utility regardless of genetic predisposition.
IN PRACTICE:
“Our findings are relevant to public health policies and practices in promoting mental health in later life through the internet, especially in countries with limited internet access and mental health services,” the investigators wrote.
SOURCE:
The study was led by Yan Luo, Department of Data Science, City University of Hong Kong, Hong Kong, China. It was published online November 18 in Nature Human Behaviour.
LIMITATIONS:
The possibility of residual confounding and reverse causation prevented the establishment of direct causality between internet use and mental health. Selection bias may have also existed due to differences in baseline characteristics between the analytic samples and entire populations. Internet use was assessed through self-reported items, which could have led to recall and information bias. Additionally, genetic data were available for participants only from England and the United States.
DISCLOSURES:
The study was funded in part by the National Natural Science Foundation of China. The investigators reported no conflicts of interest.
This article was created using several editorial tools, including artificial intelligence, as part of the process. Human editors reviewed this content before publication. A version of this article first appeared on Medscape.com.
