Bimekizumab (UCB, Bimzelx) has demonstrated high rates of 

 (HS) lesion clearance in new 3-year data from a long-term extension studies of the BE-HEARD studies announced by UCB.

“The inflammatory lesions seen in HS, particularly draining tunnels, can be devastating for people living with this disease – not only because of the pain and profound impact on life, but also due to the long-term structural damage and scarring they often cause,” Thrasyvoulos Tzellos, MD, PhD, Head Physician, Department of Dermatology, Nordland Hospital Trust, and associate professor at Institute of Clinical Medicine, University of Tromsø, Norway, said in a statement.

 “These data show that bimekizumab delivers high long-term resolution rates of these lesions, underscoring its sustained control of inflammation and potential to avoid structural damage and disease progression.”

The new data are from the 2 multicenter, randomized, double-blind, placebo-controlled Phase 3 BE HEARD I and BE HEARD II studies. The primary endpoint of both studies was Hidradenitis Suppurativa Clinical Response (HiSCR50) at Week 16. The studies had a combined enrollment of 1,014 participants, 556 of which were randomized, and then entered the open-label study, 2:2:2:1 to bimekizumab (BKZ) 320 mg every 2 weeks for the first initial 16 and then every 4 for the maintenance 32 weeks or a combination of the 2 based on HiSCR90 response (BKZ Q2W until 16 /Q2W, until 32 BKZ Q2W until 16/Q4W until 32, BKZ Q4W until 16/Q4W until 32 or placebo until 16/BKZ Q2W until 32).

 All patients who continued in the trial after Week 48 were subsequently switched to Q4W dosing by the end of year 4.

Of the participants in the open-label extension, 367 completed a lesion count assessment at year 3 and 40.1% (n = 147) achieved International HS Severity Score System (IHS4) 100 at that time point. Furthermore, 59.1% (n = 217) achieved IHS4 90 and 77.4% (n = 284) of those achieved IHS4-75.

Importantly, the proportion of patients with severe HS fell from 87.4% (n = 486) at baseline to 14.7% (54/367) at 3 years and the proportion of people with mild or inactive HS rose from 0.0% (n = 0) at baseline to 59.4% (n = 218). The mean draining tunnel count also decreased from 3.8 (standard deviation [SD], 4.3) at baseline and to 0.9 (SD, 2.0) at year 3.

Another abstract demonstrated meaningful improvements in health-related quality-of-life sustained to 3 years. UCB is presenting these data and more in 4 abstracts at the 15th Conference of the European Hidradenitis Suppurativa Foundation (EHSF), held February 4-6, 2026, in San Giljan, Malta.

“The data at EHSF showed bimekizumab’s ability to reduce HS disease severity over an extended 3-year period. The depth and durability of efficacy reinforces its importance for both people living with HS and the clinical community,” Donatello Crocetta, Chief Medical Officer, UCB, added.

 “We are proud to begin 2026 with more robust long-term clinical evidence that reflects UCB’s commitment to delivering unique treatment options, and we look forward to sharing additional bimekizumab data at AAD later this quarter.”

Bimekizumab is a humanized IgG1 monoclonal antibody, the only dual interleukin (IL)-17A and IL-17F targeting therapy approved for moderate-to-severe HS treatment in adults.

 The approved regimen for HS consists of BKZ Q2W to Week 16, then Q4W thereafter. In addition to HS, bimekizumab is also approved for treating axial spondyloarthritis, psoriatic arthritis, and plaque psoriasis in adults.

Targeting Costimulatory Pathways With Eliezer Katz, MD

After kidney transplantation, clinicians often have to navigate long-term patient outcomes, including preventing early acute rejection, preserving graft function, and ensuring overall safety.

Over the years, calcineurin inhibitors have been effective at preventing early acute rejection, but their broad mechanism of action can contribute to nephrotoxicity, metabolic disturbances, and cardiovascular complications over time.

As a result, long-term graft survival has not improved proportionally, despite reductions in acute rejection rates since the 1990s. Overall, chronic allograft dysfunction remains a major clinical challenge, often driven by a combination of calcineurin inhibitor nephrotoxicity, subclinical immune activation, medication nonadherence, and metabolic or cardiovascular complications.

Costimulatory pathways have emerged as a focal point in efforts to refine immunosuppression following kidney transplantation. These pathways act upstream in T- and B-cell activation, offering potential to reduce chronic, low-grade immune activation without broadly suppressing the immune system.

“The immune system can be activated through multiple pathways. One of these is the calcineurin pathway, while another is the costimulation pathway,” explained Eliezer Katz, MD, Chief Medical Officer at Eledon Pharmaceuticals. “CD40 ligand sits at the center of this costimulation pathway. By blocking CD40 ligand, tegoprubart prevents the immune system from mounting a full attack on the graft.”

Costimulatory blockade occurs earlier in the immune activation process than CNIs, which act downstream after T cells are engaged. Early intervention at this level may reduce memory T-cell formation, preserve regulatory T-cell signaling, and potentially mitigate chronic immune-mediated injury that contributes to long-term graft dysfunction.

Mechanistic Rationale for CD40 Ligand Blockade

The CD40–CD40 ligand (CD40L) pathway sits at the intersection of T-cell activation, B-cell maturation and class switching, germinal center formation, and antibody-mediated rejection biology. This makes it particularly relevant to humoral rejection, chronic antibody-mediated injury, and long-term graft fibrosis.

Early anti-CD40L antibodies were limited by thromboembolic events, likely due to CD40L expression on activated platelets and Fc-mediated crosslinking that triggered platelet aggregation. Tegoprubart, a humanized monoclonal antibody targeting CD40L, is engineered to minimize Fc-mediated platelet activation while selectively disrupting cellular and humoral costimulatory signaling.

Early Clinical Evaluation: Phase 1b and Phase 2 BESTOW Trial

In the phase 1b trial, over 24 months, tegoprubart had an acceptable safety profile. All patients experienced ≥1 TEAE, while SAEs were reported for 3 patients, and AESIs were reported for 7 patients. No cases of biopsy-proven acute rejection, de novo DSA, delayed graft function, or graft loss were reported.

Investigators observed functional eGFR levels were restored within 1 month after transplantation and generally maintained over 24 months. At 12 and 24 months, mean (SD) eGFRs were 67.0 (19.85) mL/min/1.73 m² and 74.2 (24.91) mL/min/1.73 m², respectively.

In the ongoing 12-month, randomized, head-to-head phase 2 BESTOW trial, investigators are evaluating tegoprubart, compared with a standard tacrolimus treatment regimen in kidney transplant recipients, with a target enrollment of > 120 participants across multiple global sites.

All participants received standard induction and maintenance therapy, including rATG, mycophenolate, and steroids. The primary endpoint was the change in estimated glomerular filtration rate (eGFR) at 12 months. Secondary endpoints included biopsy-proven acute rejection, graft survival, composite efficacy failure, delayed graft function, donor-specific antibodies, and new-onset diabetes after transplant (NODAT).

Preliminary 12‑month data indicate mean eGFR values of 69 mL/min/1.73 m² in the tegoprubart group versus 66 mL/min/1.73 m² in the tacrolimus group.

Upon subgroup analyses, investigators observed increased eGFR in some donor subgroups, including living-related donors and higher Kidney Donor Profile Index cases.

In terms of safety, biopsy-proven acute rejection occurred in 20.6% compared to 14.1% of participants, and composite efficacy failure was 22% compared to 17%, respectively, indicating tegoprubart maintained immunosuppressive efficacy within the study’s predefined margin.

“Most transplant rejection occurs in the first year, making early control critical. Maintaining kidney function during this period, and beyond, is essential for long-term graft survival,” Katz said. “By targeting CD40 ligand and preserving kidney function, tegoprubart has the potential to improve long-term outcomes and allow patients to enjoy their grafts for many years.”

While the data are early and further evaluation is ongoing, mechanistic and clinical rationale suggest targeted CD40L blockade may offer a more precise approach to immunosuppression, explains Katz. By modulating immune activation without broadly suppressing T-cell function, clinicians may be able to maintain graft protection while mitigating systemic toxicities associated with calcineurin inhibitors.

Long-term kidney allograft survival remains constrained by calcineurin inhibitor–associated nephrotoxicity and chronic immune-mediated injury, despite marked reductions in early acute rejection. Costimulatory pathway modulation, particularly CD40–CD40L blockade, offers an upstream strategy to attenuate T- and B-cell activation, potentially limiting memory T-cell development and humoral injury. Tegoprubart is engineered to avoid Fc-mediated platelet activation that hampered earlier anti-CD40L agents. Early trials suggest preserved renal function with acceptable safety, with ongoing randomized comparisons versus tacrolimus.

Targeting Costimulatory Pathways in Kidney Transplant With Eliezer Katz, MD

Eric White, MD, global clinical development lead for rheumatology and pulmonology at Boehringer Ingelheim Pharmaceuticals

AI CT Tool for Early Pulmonary Fibrosis Detection Enters Phase 3, With Eric White, MD

Brainomix announced on January 20, 2026, that Boehringer Ingelheim has selected them to provide quantitative, automated high-resolution CT (HRCT) imaging biomarkers as a co-primary endpoint in the Phase 3 DROP-FPF study.

Early identification remains one of the most persistent challenges in interstitial lung disease and 

, where patients are often diagnosed after irreversible lung damage has already occurred. DROP-FPF aims to shift that paradigm by studying whether intervening earlier with nerandomilast, before symptoms and measurable lung function decline, can meaningfully alter the disease trajectory.

, Eric White, MD, global clinical development lead for rheumatology and pulmonology at Boehringer Ingelheim Pharmaceuticals, emphasized the unmet need this trial addresses.

“That there are no approved options for these individuals, and quite honestly, we're not entirely certain what to do with them,” White said. “When we see them, we tell them, ‘you might have something there, and it might turn into a disease later on,’ but we can't give them much more than that, and so this is one of the first studies to let us start to understand what that aspect of the disease, the very, very, very early disease, how that behaves, and whether intervention with a known, effective medication will improve their outcomes.”

DROP-FPF is a phase 3b randomized, placebo-controlled trial evaluating the safety and effectiveness of nerandomilast (Jascayd) in individuals with interstitial lung abnormalities and a family history of pulmonary fibrosis. A defining feature of DROP-FPF is its use of automated, quantitative high-resolution CT (HRCT) imaging biomarkers as a co-primary endpoint, which is the first phase 3 interstitial lung disease trial to do so.

White noted that imaging changes typically precede declines in forced vital capacity (FVC), the standard physiologic endpoint used in pulmonary fibrosis trials. As therapies improve and FVC decline becomes more modest, relying on lung function alone may no longer be sufficient to detect meaningful treatment effects.

“The nice thing about using a quantitative HRCT is that the computers can see changes in the images well before the human eye can,” White said.

The trial will use Brainomix’s FDA-cleared e-Lung platform to quantify metrics, including the reticular vascular score and total disease extent, providing a granular view of early structural changes. White pointed to growing evidence that quantitative CT changes predict lung function decline, mortality, and overall outcomes, supporting their clinical relevance.

DROP-FPF will enroll approximately 80 participants using a rolling enrollment design, with each individual followed for ≥ 2 years. Beyond imaging progression, investigators will track symptom development, including cough, dyspnea, and fatigue, to better define when early interstitial lung disease becomes clinically apparent. Although the study is not expected to change practice immediately, White said it could provide critical evidence supporting earlier identification, closer monitoring, and earlier intervention, laying the groundwork for a more proactive approach to pulmonary fibrosis care.

“We also think [using a quantitative HRCT is] important because, as more and more drugs come to market for treating patients with pulmonary fibrosis, our ability to [detect] the change over time in breathing tests and forced vital capacity is diminishing, so it's going to be harder to determine whether a drug is doing something for a patient purely based on the forced vital capacity,” White said. “The imaging study will show us what parts of the lungs are being destroyed before it impacts the amount of volume that comes out. Because of that, the imaging should give us quite a bit of information before we even get to the point where people are starting to lose lung volumes.”

Asundexian Cuts Risk of Second Stroke - Results from OCEANIC-STROKE

Asundexian, an investigational oral Factor XIa (FXIa) inhibitor in development by Bayer, has shown its superiority to placebo in preventing 

 in patients after a non-cardioembolic ischemic stroke or high-risk transient ischemic attack (TIA), based on results from the pivotal phase 3 OCEANIC-STROKE trial.

Despite a variety of treatment options, the risk of secondary stroke remains substantial – roughly 1 in 10 ischemic stroke survivors will experience another within 1 year, and 1 in 5 will have another stroke within 5 years. Secondary strokes are commonly more disabling and are associated with higher mortality and a greater risk of 

. Combining current strategies can reduce the risk of secondary stroke but has been associated with an increased bleeding risk.

“I think it’s really important to recognize that we’re always concerned that we’re adding bleeding risk,” Andrew Russman, DO, neurologist and section head of stroke and vascular neurology at the Cleveland Clinic, told 

 in an exclusive interview. “But that was not the case with asundexian in this study. Essentially, patients benefited from a reduction in their ischemic stroke risk without a concomitant increase in bleeding risk. And this is critically important.”

OCEANIC-STROKE was a multicenter, international, randomized, placebo-controlled, double-blind, parallel group, event-driven phase 3 study, conducted at 741 locations worldwide. Investigators enrolled patients who were ≥18 years old with acute non-cardioembolic stroke or high-risk TIA and systemic or cerebrovascular 

 or acute non-lacunar infarct. Patients were excluded if they had ischemic stroke ≤7 days before the index event, a history of atrial fibrillation or flutter, left ventricular thrombus, mechanic valve, or other cardioembolic source of stroke, among other criteria.

The study’s primary endpoints were time to first occurrence of ischemic stroke and time to first occurrence of International Society on Thrombosis and Hemostasis (ISTH) major bleeding, both up to 31 months. Secondary outcomes included time to first occurrence of ischemic and hemorrhagic strokes, time to first occurrence of a composite of cardiovascular death, myocardial infarction, or stroke, and time to first occurrence of all-cause mortality, among others.

A total of 12,327 patients were enrolled in the trial; of these, 43% had large-artery atherosclerosis, 23% had small-vessel occlusion, 30% had stroke of undetermined etiology, 3% had other etiology, and 2% had cardioembolic stroke. Patients were randomly assigned in a 1:1 ratio to receive either oral asundexian once daily or matching placebo.

Russman and colleagues found that asundexian reduced ischemic stroke by 26% (HR, 0.74; 95% CI, 0.65-0.84; 

 <.0001) with no increase in risk of ISTH major bleeding. This was consistent across all subgroups, including age, sex, index event, stroke subtype, National Institutes of Health Stroke Scale (NIHSS), and acute stroke therapy.

Secondary endpoints also showed that asundexian reduced ischemic and hemorrhagic stroke risk by 26% (6.6% vs 8.8%; HR, 0.74; 95% CI, 0.65-0.84; 

 <.0001) compared to placebo. Additionally, investigators saw no increase in the rate of ISTH major bleeding between asundexian and placebo (1.9% vs 1.7%; HR, 1.1; 95% CI, 0.85-1.44). The risk of bleeding was also similar compared to rates in the placebo arm.

“The benefit of the Factor XIa inhibitors is that they’re relatively selective; they act against the bad clot without harming the good clotting that’s part of healing,” Russman told 

. “Anticoagulants in general act against a variety of clotting, whether it’s the kind we need for healing or the bad kind of clotting that’s part of a pathologic process of a clot that could form and travel to the brain and cause a stroke.”

OCEANIC-STROKE: Asundexian Reduces Stroke Risk Without Increasing Bleeding, With Andrew Russman, DO

How the 2025 KDIGO Guidelines Are Personalizing IgA Nephropathy Care, With Gerald Appel, MD

 and IgA vasculitis (IgAV), in tandem with the evolving therapeutic landscape, has introduced significant changes to clinical care, essentially individualizing treatment strategies.

These clinical shifts included a reassessment of treatment targets for key biomarkers and a greater emphasis on addressing the underlying mechanisms driving disease progression.

From a clinician's perspective, Gerald Appel, MD, professor of clinical medicine at Columbia University, IgAN has shifted management toward a more personalized approach, supported by a broader range of therapeutic options, combination strategies, and long-term patient-centered goals.

In practice, this personalization is increasingly guided by biopsy findings, baseline proteinuria, and patient-specific risk factors, allowing clinicians to tailor therapy based on dominant inflammatory or hemodynamic drivers of disease.

“Kidney biopsy can be very helpful in this regard. If a patient has significant scarring, therapy may focus more on ACE inhibitors, ARBs, endothelin receptor antagonists, and SGLT2 inhibitors,” said Appel.” If inflammation predominates, we may target that pathway more aggressively.”

Notably, the 2025 KDIGO IgAN guideline encourages kidney biopsy in adults with suspected IgAN and proteinuria ≥0.5 g/d. This represents a shift from the 2021 guideline, which emphasized reducing proteinuria to <1 g/d.

Additionally, the guideline authors underscore proteinuria as a validated surrogate marker for long-term renal outcomes, supporting both earlier diagnostic evaluation and more aggressive treatment targets. The updated guideline reduces the recommended target to <0.5 g/d, with an ideal goal of <0.3 g/d, regardless of treatment status, reflecting evidence linking persistent proteinuria to an increased lifetime risk of kidney failure.

A major new concept in the 2025 guideline is to initiate treatment with therapies to prevent or reduce pathogenic IgA production and IgA/IgA and IgA/IgG immune complex formation, along with therapies to manage the consequences of existing IgAN-induced nephron loss.

“For example, targeted-release budesonide (Tarpeyo) acts on the distal ileum, specifically the Peyer’s patches, where it reduces the production of galactose-deficient IgA1 and immune complexes. This, in turn, reduces proteinuria and kidney injury,” explained Appel. “Other emerging agents also block the production of galactose-deficient IgA1 and immune complexes, while some newer therapies primarily focus on reducing proteinuria and inflammation. We now have multiple points of intervention to alter the course of the disease, and KDIGO highlights this approach.”

The 2025 KDIGO recommendations emerge amid a rapidly evolving IgAN therapeutic landscape, with 10 agents in late-phase clinical development demonstrating comparable proteinuria reductions. These late-phase programs span multiple mechanistic classes, including endothelin pathway inhibition, complement modulation, and targeted immunosuppression, reinforcing the guideline’s emphasis on combination and mechanism-driven therapy.

Collectively, these advances have the potential to expand clinician choice and create new opportunities to individualize disease management.

As therapeutic options continue to expand, the 2025 KDIGO guideline provides a framework for integrating emerging agents into individualized treatment strategies aimed at delaying or preventing kidney failure.
