From FLOW to REMODEL: Understanding Semaglutide in CKD, With Katherine Tuttle, MD

Chronic kidney disease (CKD) in the setting of type 2 diabetes represents one of the most high-risk clinical scenarios in medicine, driven not only by progression to kidney failure but by a substantial burden of cardiovascular morbidity and premature death.

While recent therapeutic advances have improved outcomes, understanding how these treatments exert their benefits has remained a critical gap. The REMODEL trial was designed to address this question, offering a detailed mechanistic complement to landmark outcome data on semaglutide’s benefit in this patient population.

 at the World Congress of Nephrology (WCN) in Yokohama, Japan, Katherine Tuttle, MD, explained that REMODEL builds on the success of the FLOW trial, which demonstrated significant reductions in kidney events, cardiovascular outcomes, and all-cause mortality with semaglutide, ultimately leading to the agent’s US Food and Drug Administration approval for this indication. While those findings established clinical efficacy, they did not fully explain the underlying biology. REMODEL, she explains, was specifically designed as a mechanistic “deep dive,” integrating advanced imaging, kidney biopsy, and transcriptomic analyses to uncover how these benefits are achieved.

The study confirmed key clinical findings, including a 40% reduction in albuminuria and stabilization of kidney function. Of note, functional MRI revealed significant reductions in kidney fat far exceeding overall weight loss as well as improved vascular health, reflected by decreased renal arterial resistance. Markers of fibrosis progression were halted in the treatment group, suggesting a protective structural effect.

Biopsy data provided further depth. Tuttle highlights a marked reduction in peri-glomerular immune cells, particularly natural killer T cells, alongside broad downregulation of fibroinflammatory pathways, pointing to a direct anti-inflammatory effect within the kidney microenvironment. Transcriptomic analyses additionally identified glomerular endothelial cells as a key site of regulation, supporting the concept of improved integrity of the glomerular filtration barrier and even evidence of repair, not just stabilization, over time.

She emphasizes that these results align closely with preclinical models, strengthening confidence in translational research approaches. Beyond individual findings, the study design itself represents a major advance, demonstrating that rigorous mechanistic trials can be successfully conducted in humans.

Looking ahead, Tuttle underscores the implications for precision medicine. While current therapies are broadly applied, variability in response remains a major challenge. By linking mechanistic signatures to treatment outcomes, REMODEL provides a framework for identifying responders and tailoring therapy. Ultimately, she suggests, this approach could shift care toward selecting the right treatment for the right patient at the right time, marking a significant step forward in the management of diabetic kidney disease.

Upadacitinib Safe, Effective Over 48 Weeks for Non-Segmental Vitiligo, With Thierry Passeron, MD, PhD

Upadacitinib is both safe and effective over 48 weeks among patients with 

, new findings suggest, with no new safety signals or major adverse cardiovascular events (MACE) identified.

These late-breaking data, the result of the Viti-Up-1 and Viti-Up-2 studies, were released during the 

2026 American Academy of Dermatology (AAD) Annual Meeting

 editorial team spoke on-site with trial investigator Thierry Passeron, MD, PhD, professor and chair of the Department of Dermatology at the Université Côte d'Azur in Nice, France.

“Unfortunately, so far, there is no systemic treatment approved for vitiligo, and there is still a high unmet need for the patients suffering from vitiligo,” Passeron explained.

Non-segmental vitiligo, an autoimmune inflammatory disease impacting the skin, is characterized by patients’ loss of melanocytes. This can lead to unpredictable skin depigmentation. Passeron stressed the lack of systemic medications approved for the condition, describing additional options as necessary.

Passeron and colleagues reported in this study on the efficacy and safety of upadacitinib, a selective once-daily Janus kinase (JAK) 1 inhibitor, 15 mg in adults and adolescents with non-segmental vitiligo. It was studied across 48 weeks in this pair of identical, pivotal phase 3 analyses.

In his interview, Passeron noted most of the patients were Fitzpatrick skin types 3 and 4, further describing those treated with upadacitinib in the study as being a severe disease population. The subjects were both adults and adolescents aged ≥ 12 years with this skin disease involving the face and body.

They all had a Facial Vitiligo Scoring Index (F-VASI) ≥ 0·5 and a Total Vitiligo Area Scoring Index (T-VASI) ≥ 5. The subjects were randomized 2:1 to be treated either with upadacitinib 15 mg or placebo once daily. There were 614 individuals involved across Viti-Up-1 (n=308) and Viti-Up-2 (n=306) in total.

“Two-thirds of the population were active, and three-fourths had T-VASI above 10…and the mean duration of the vitiligo was about 15 years,” Basseron said. “Most of them had vitiligo that had already been treated by topical treatment of phototherapy.”

In this poster at AAD, the treatment with upadacitinib was described as providing clinically meaningful repigmentation among adult and adolescent patients with non-segmental vitiligo.

 Passeron and coauthors’ safety data through week 48 were described as consistent with the overall profile for upadacitinib.

Specifically, they noted a lack of reports of adjudicated MACE, adjudicated gastrointestinal (GI) perforations, adjudicated venous thromboembolic events (VTE), lymphoma, active tuberculosis, non-melanoma skin cancer, or opportunistic infections outside of herpes zoster in either analysis.

 Among the most often reported TEAEs, examples included acne, upper respiratory infection, nasopharyngitis, and headache. There were 4 serious infections reported among patients in the Viti-Up-1 upadacitinib cohort, though none led to treatment cessation.

Your Patient's New Therapist Is an AI. Now What?

Watch the full expert dynamic feature above.

In your clinic, you may hear patients say, “Chat told me this” or “Chat told me that.” Numerous individuals use ChatGPT, colloquially referred to as “Chat,” to get quick, convenient 

advice. This can be dangerous, depending on what the chatbot says, potentially providing patients with advice you would never, in a million years, give.

“More often, it's actually deleterious where information is cherry-picked, and the context is not always understood,” said Richard Miller, MD, a staff psychiatrist at Elwyn Adult Behavioral Health in Cranston, RI. “Patients are kind of going on an extended trip…to get the information that they're looking for…. maybe [a] particular answer. It's not always accurate.”

Despite the danger, AI can also be helpful in the psychiatry field. AI can provide a new perspective and can augment, not replace, treatment.

 Editorial Team put together a feature examining the benefits, dangers, and ethics surrounding AI use in psychiatry. Millions of Americans struggle to access mental health care, with waitlists sometimes lasting 3 to 6 months.

These individuals, desperate for mental health advice, turn to AI. As Darlene King, MD, from the University of Texas Southwest Medical Center, said, using AI as a therapist is like getting mental health advice from a friend, who can very well give bad advice.

Dominic Sisti, PhD, from Penn Medicine, discussed the ethical concerns of AI in psychiatry. Vulnerable populations may be susceptible to abusing AI and can even go as far as asking ChatGPT ways to self-harm. “How would these AI platforms [respond] to a patient who is indicating they have suicidal ideation or behavior?” he asked. “How might these platforms recognize elevated risk for self-harm or harm to others?

Sisti stressed the need for guardrails on age restrictions, redirection protocols, and HIPAA compliance standards. He also said there is a need for platforms to distinguish between an investigator asking about suicide methods versus someone in crisis.

Other than mental health advice, AI can assist in screening. In 2024, a study showed the promise of Sonde Health’s mental fitness vocal biomarker tool to 

identify depression from the sound of a voice

 Another study showed the potential of MoodCapture, a smartphone application using AI to 

detect the onset of depression based on facial cues 

More recently, a study showed AI can predict treatment response in major depressive disorder (MDD). In the 

phase 2b OLIVE trial assessing BH-200 (nelivaptan)

, a selective vasopressin V1b receptor antagonist, a proprietary genetic tool stratified patients by vasopressin-related biomarkers.

 Patients with lower peripheral but higher central vasopressin activity had a stronger antidepressant response, supporting biomarker-guided patient selection.

AI can also help with psychiatrists’ day-to-day responsibilities. For instance, Suki AI, Heidi, and DeepScribe, among others, are designed for clinician documentation.

As AI becomes more commonplace, experts recommend asking about its use non-judgmentally during routine history-taking. Although potentially dangerous, AI can be beneficial if used with a “human in the loop,” according to Sisti.

A phase 3 randomized trial found mavacamten (Camzyos) significantly reduced left ventricular outflow tract (LVOT) obstruction in adolescents with symptomatic 

obstructive hypertrophic cardiomyopathy (oHCM)

The findings from the SCOUT-HCM trial were presented as a late-breaking clinical trial at the 

American College of Cardiology's Annual Scientific Session (ACC.26)

 and, according to Bristol Myers Squibb, represent the first prospective phase 3 evidence for a cardiac myosin inhibitor in a pediatric oHCM population.

“Pediatric HCM is a rare cardiac disorder that is associated with severe, sometimes life-threatening, symptoms,” said principal investigator Joseph Rossano, MD, chief of the Division of Cardiology at Children’s Hospital of Philadelphia.

 “With no approved therapies for pediatric patients with oHCM and current recommendations for pharmacological therapy primarily extrapolated from evidence obtained from adult studies, the positive results of this trial represent a significant advance in the field of pediatric cardiology and the potential for a meaningful new therapy for adolescent patients if approved by the FDA.”

SCOUT-HCM was a double-blind, randomized, placebo-controlled phase 3 trial enrolling adolescents aged 12 to less than 18 years with NYHA class II or III oHCM across 28 sites in 9 countries. Eligible patients had a Valsalva LVOT gradient of 30 mm Hg or greater, a maximal LVOT gradient of 50 mm Hg or greater, and a left ventricular ejection fraction (LVEF) of 60% or greater. Patients with HCM phenocopies such as Noonan syndrome or Fabry disease were excluded.

Of 65 patients screened, 44 were randomized 1:1 to mavacamten or placebo for 28 weeks. The 23 patients in the mavacamten group and 21 in the placebo group had a mean age of approximately 14.7 years, 83% to 86% were on background beta-blocker therapy, and approximately half carried a pathogenic or likely pathogenic HCM mutation.

Investigators pointed out the mean baseline Valsalva LVOT gradient was 78.4 mmHg in the mavacamten group and 80.8 mmHg in the placebo group. Additionally, mavacamten was initiated at 5 mg once daily for most patients, with dose adjustment permitted based on echocardiographic assessment.

The primary endpoint was the change from baseline to week 28 in Valsalva LVOT gradient. Secondary outcomes of interest included the change from baseline to week 28 in resting and postexercise LVOT gradients, the maximal left ventricular wall thickness, and the ratio of early mitral inflow velocity to mitral annular early diastolic velocity (E/e′ ratio).

48 mmHg Reduction in Valsalva LVOT Gradient

At week 28, the least-squares mean change in Valsalva LVOT gradient was -48.5 mmHg in the mavacamten group versus -0.5 mm Hg in the placebo group, a between-group difference of -48.0 mmHg (95% CI, -67.7 to -28.3; 

Analysis of secondary outcomes of interest also favored mavacamten, including reductions in resting LVOT gradient (difference, -47.0 mm Hg; 95% CI, -62.7 to -31.4), postexercise LVOT gradient (difference, -41.7 mm Hg; 95% CI, -59.7 to -23.7), maximal LV wall thickness (difference, -1.8 mm; 95% CI, -3.4 to -0.2), and average E/e' ratio (difference, -3.4; 95% CI, -5.1 to -1.6). Investigators also called attention to exploratory analyses pointing to reductions in NT-proBNP and high-sensitivity cardiac troponin levels with mavacamten.

Overall adverse event rates were similar between groups (78% mavacamten vs 81% placebo). Serious adverse events occurred in 2 patients per arm. A single patient in the mavacamten group had 2 episodes of syncope deemed related to study drug and another had an inappropriate ICD shock considered unrelated. No patient in either group died or experienced an LVEF below 50%, and no cases of atrial fibrillation or symptomatic heart failure were reported.

Investigators highlighted several key limitations in their study to consider. These included the small sample size, restriction to ages 12 and older, a predominantly White study population, and the 28-week placebo-controlled follow-up period.

“The SCOUT-HCM results underscore the potential for [mavacamten] to become the first CMI for adolescents, reinforcing our leadership in the CMI space and our role in reshaping the scientific understanding of oHCM and how the disease is diagnosed, evaluated and potentially treated,” said Cristian Massacesi, MD, executive vice president, chief medical officer, and head of development at Bristol Myers Squibb.

 “With these meaningful safety and efficacy data, we are excited about the potential to provide a paradigm-changing treatment for adolescents and their families.”

Mavacamten Shows Benefit for Pediatric Patients in SCOUT-HCM Trial

REZOLVE-AD: Rezpegaldesleukin Shows Consistent Efficacy Across Atopic Dermatitis Severity, With Raj Chovatiya, MD, PhD

Rezpegaldesleukin (Nektar Therapeutics), novel IL-2 receptor agonist targeting regulatory T cells has demonstrated dose-dependent, statistically significant improvements in atopic dermatitis outcomes across both moderate and severe disease — with consistent responses observed regardless of baseline severity, geographic region, or asthma comorbidity status.

These findings are from the phase 2b REZOLVE-AD study (NCT06136741) presented at the 

 held in Denver, Colorado, from March 27-31, by Raj Chovatiya, MD, PhD, MSCI, FAAD, Associate Professor at Rosalind Franklin University of Medicine and Science Chicago Medical School and Founder and Director of the Center for Medical Dermatology and Immunology Research in Chicago. 

spoke with Chovatiya to learn more about REZOLVE-AD, which enrolled 393 patients with moderate-to-severe atopic dermatitis not previously treated with a JAK inhibitor or biologic. Participants were randomized 3:3:3:2 to rezpegaldesleukin 24 µg/kg every 2 weeks (n = 104), 18 µg/kg every 2 weeks (n = 106), 24 µg/kg every 4 weeks (n = 110), or placebo every 2 weeks (n = 73) over a 16-week induction period. Chovatiya described the mechanism as fundamentally distinct from existing approved therapies — rather than blocking active inflammation downstream, rezpegaldesleukin expands and activates Tregs via preferential binding to the IL-2 receptor complex, targeting the resolution phase of immune dysregulation.

On the primary endpoint of mean percent EASI reduction at week 16, the 24 µg/kg q2w arm achieved 61% improvement versus 31% for placebo (

 <.001), with the 18 µg/kg q2w and 24 µg/kg q4w arms achieving 58% (

 <.001), respectively — demonstrating clear dose-dependence. The finding that most engaged Chovatiya was the consistency across baseline disease severity: in patients with moderate disease (vIGA = 3), EASI improvements were 59%, 58%, and 54% across the three active arms versus 32% for placebo; in patients with severe disease (vIGA = 4), improvements were 63%, 58%, and 50% versus 29% — nearly identical trends suggesting baseline severity did not meaningfully modulate treatment response. EASI-75 and EASI-90 response rates showed the same pattern across both moderate and severe subgroups. A forest plot analysis of EASI-75 response for the 24 µg/kg q2w arm further confirmed consistent treatment effect across baseline EASI above and below 21, geographic region, and presence or absence of asthma comorbidity — all favoring rezpegaldesleukin over placebo.

On safety, injection site reactions occurred in 69.7% of all rezpegaldesleukin-treated patients versus 4.1% for placebo, nearly all mild-to-moderate; other TEAEs occurring at ≥5% frequency included eosinophilia (7.8% vs. 2.7%), pyrexia (6.3% vs. 2.7%), headache (6.3% vs. 4.1%), upper respiratory tract infections (5.9% vs. 5.5%), and arthralgia (5.0% vs. 1.4%), with no increased risk of conjunctivitis, oral ulcers, malignancy, or infections including oral herpes. The phase 3 ZENITH-AD program is in final planning with initiation expected in Q2 2026, with Chovatiya noting that the Treg-modulating mechanism raises the prospect of extended dosing intervals or treatment breaks — a meaningfully different proposition from the continuous cytokine inhibition model that defines the current standard of care.

“One of the exciting things about rezpeg is that it may potentially allow for... extended dosing intervals [and] potentially breaks off therapy, given that it's modulating a regulatory T cell, as opposed to inhibiting an activated T cell. So this is really what next phase of studies is going to be designed to test,” Chovatiya said.

Nektar Therapeutics also presented late breaking data on rezpegaldesleukin in alopecia areata, from the phase 2b REZOLVE-AA study (NCT06340360).

also caught up with that presenter David Rosmarin, MD, Chair of the Department of Dermatology and Associate Professor of Dermatology at Indiana University School of Medicine in Indianapolis, during the meeting.
