The role of venous capacity in fluid retention with endothelin A antagonism: Mathematical modelling of the RADAR trial

Article

Author: Hallow, K. Melissa ; Ahlstrom, Christine ; Greasley, Peter J. ; Ambery, Philip ; Hamren, Bengt ; Yu, Hongtao ; Boulton, David W. ; Khan, Anis A. ; Lambers Heerspink, Hiddo J.

Abstract:

Background and Purpose:

Endothelin‐1 (ET‐1) receptor A (ETA) antagonists reduce proteinuria and prevent renal outcomes in chronic kidney disease (CKD) patients, but their utility has been limited because of associated fluid retention, resulting in increased heart failure risk. Understanding the mechanisms responsible for fluid retention could result in solutions that preserve renoprotective effects while mitigating fluid retention, but the complexity of the endothelin system has made identification of the underlying mechanisms challenging.

Approach:

We utilized a previously developed mathematical model of ET‐1 kinetics, ETA receptor antagonism, kidney function, haemodynamics, and sodium and water homeostasis to evaluate hypotheses for mechanisms of fluid retention with ETA antagonism. To do this, we simulated the RADAR clinical trial of atrasentan in patients with type 2 diabetes and CKD and evaluated the ability of the model to predict the observed decreases in haematocrit, urine albumin creatinine ratio (UACR), mean arterial pressure (MAP), and estimated glomerular filtration rate (eGFR).

Background and Key Results:

An effect of ETA antagonism on venodilation and increased venous capacitance was found to be the critical mechanism necessary to reproduce the simultaneous decrease in both MAP and haematocrit observed in RADAR.

Conclusions and Impact:

These findings indicate that fluid retention with ETA antagonism may not be caused by a direct antidiuretic effect within the kidney but is instead be an adaptive response to venodilation and increased venous capacity, which acutely tends to reduce cardiac filling pressure and cardiac output, and that fluid retention occurs in an attempt to maintain cardiac filling and cardiac output.

Clinical trial designs to assess treatment effects on glomerular filtration rate decline

Article

Author: Little, Dustin J ; Postmus, Douwe ; Gasparyan, Samvel B ; Frison, Lars ; Heerspink, Hiddo J L ; Wanner, Christoph ; Jongs, Niels

Glomerular filtration rate (GFR) decline is used as surrogate endpoint for kidney failure. Interventions that reduce chronic kidney disease (CKD) progression often exert acute GFR reductions which differ from their long-term benefits and complicate the estimation of long-term benefit. Here, we assessed the utility of two alternative trial designs (wash-out design and active run-in randomized withdrawal design) that attempt to exclude the impact of acute effects. Post-hoc analyses of two clinical trials that characterized the effect of an intervention with acute reductions in GFR were conducted. The two trials included a wash-out period (EMPA-REG Outcome testing empagliflozin vs placebo) or an active run-in period with a randomized withdrawal (SONAR testing atrasentan vs placebo). We compared the drug effect on GFR decline calculated from the first on-treatment visit to the end of treatment (chronic slope in a standard randomized trial design) with GFR change calculated from randomization to end of wash out, or GFR change from treatment-specific baseline GFR values (GFR at start-of-run-in for placebo and end-of-run-in for atrasentan) until end-of-treatment. The effect of empagliflozin versus placebo on chronic GFR slope was 1.72 (95% confidence interval 1.49-1.94) mL/min/1.73 m²/year, similar to total GFR decline from baseline to the end of wash-out period using a linear mixed model 1.64 (1.44-1.85) mL/min/1.73 m²/year). The effect of atrasentan versus placebo on chronic GFR slope was 0.72 (0.32-1.11) mL/min/1.73 m²/year, similar to total slope from a single slope model when estimated from treatment specific baseline GFR values 0.77 (0.39-1.14) mL/min/1.73 m²/year). Statistical power of the two designs outperformed the standard randomized design. Thus, wash-out and active-run-in randomized-withdrawal trial designs are appropriate models to compute treatment effects on GFR decline.

The role of endothelin receptor antagonists in IgA nephropathy

Review

Author: Wong, Muh Geot ; Hunter‐Dickson, Mitchell

Abstract:

There is growing evidence of endothelin receptor antagonists (ERAs) in renoprotection in proteinuric kidney disease including IgA nephropathy (IgAN). Here, we review current evidence, including the use of sparsentan, atrasentan and zibotentan in IgAN. Recent trails of combination therapy including SGLT2 inhibitors and ERAs suggest possible benefit in further reduction of proteinuria and reducing ERA fluid‐retention side effects although more evidence is needed for clinical applications.

American Society of Nephrology, Oct. 23-27

The annual meeting of the American Society of Nephrology (Kidney Week) was held this year from Oct. 23 to 27 in San Diego, attracting attendees from around the world, including nephrology specialists, researchers, scientists, and other health care professionals. The conference featured presentations focusing on the latest advances in the management of patients with kidney diseases and related disorders. In one study, Hardik Dineshbhai Desai, M.B.B.S., of the Gujarat Adani Institute of Medical Science in Bhuj, India, and colleagues found that chronic kidney disease (CKD) attributable to metabolic risk factors nearly tripled in women in terms of mortality between 1990 and 2021, with significant regional and income-related disparities evident. The authors analyzed data from the Global Burden of Disease 2021 study and found that the annual percentage change (APC) in deaths due to CKD attributable to metabolic risk factors in women increased 3.39 percent from 1990 to 2021. While total percentage change in death increased by 180.91 percent (nearly tripled/close to threefold from 1990 to 2021), the growth rate, as indicated by the APC, has remained fairly consistent across decades, showing a slight upward trend in the most recent period (2010 to 2021). Regionally, the highest APC in incidence was observed in Andean Latin America (3.52 percent) and Central Latin America (3.03 percent). In terms of World Health Organization income level, the highest APC in incidence was observed in middle-income regions, followed by high-income regions. For the mortality rate, the highest APC was observed in high-income regions (3.23 percent). "This calls for urgent global health strategies focusing on prevention, early detection, and management of CKD, especially in regions and populations most at risk," Desai said. "Clinicians should focus on gender-sensitive screening for CKD, especially targeting women with a history of gestational diabetes or preeclampsia, as these conditions are linked to an increased risk of future metabolic syndrome and renal impairment. Integrating nephrology and women's health in clinical practice can enhance early detection and intervention, thus improving outcomes." Press Release In another study, Giselle Peschard, M.D., of the University of California in San Francisco, and colleagues found that integrating multiple biomarkers into distinct kidney health dimensions provides valuable insights into the biological processes underlying CKD in individuals with diabetes. Novel dimensions of kidney health were developed by combining a set of 17 urine and plasma biomarkers that had been individually associated with CKD progression in prior studies. The authors evaluated findings from two cohorts that included persons with diabetes and CKD: the National Institute of Diabetes and Digestive and Kidney Diseases Chronic Renal Insufficiency Cohort (CRIC) and the REasons for Geographic And Racial Differences in Stroke. The researchers identified three kidney health dimensions, which were labeled as follows: systemic inflammation and filtration score (including plasma TNFR-1, TNFR-2, suPAR, and SDMA); tubular function score (including urine EGF, ADMA, and SDMA); and tubular damage score (including urine α1m, KIM-1, and MCP-1). Each was associated with CKD progression or mortality, independent of clinical risk factors, estimated glomerular filtration rate (eGFR), and albuminuria. The investigators noted that higher tubular damage and lower tubular function scores were associated with a higher risk for CKD progression in CRIC, while higher systemic inflammation and filtration scores were associated with a higher mortality risk in both cohorts. "Predominantly capturing the health of the kidney tubules, our findings demonstrate that there are important indicators of kidney health beyond the current clinical measures of eGFR and albuminuria," Peschard said. "These kidney health dimensions may help us to understand the heterogeneity of CKD patterns and risk for persons with diabetes." Press Release Millie Shah, Ph.D., from Biogen in Cambridge, Massachusetts, and colleagues furthered the understanding of the role of CD38+ antibody-secreting cells (plasma cells and plasmablasts) in immunoglobulin A nephropathy (IgAN) pathogenesis. The authors evaluated whole blood and serum collected from patients with IgAN before, during, and after felzartamab treatment. The investigators found that the targeting of CD38+ plasma cells and plasmablasts with felzartamab resulted in durable reductions of disease-relevant biomarkers in IgAN study participants. Disease-associated IgA and galactose-deficient IgA1 were reduced following felzartamab treatment and remained reduced for at least 18 months and up to 10 months off-treatment, respectively. In contrast, the body's IgG titers were modestly reduced and recovered within four months off-treatment, suggesting the preservation of components of the body's adaptive immune response. "Direct depletion of CD38+ cells may offer clinical benefit without continuous dosing, potentially lowering patient burden and offering improved tolerability," Shah said. "Further study of felzartamab treatment in IgAN is planned in an upcoming phase 3 study." The study was funded by Biogen, which is developing felzartamab.

Novartis oral Fabhalta® (iptacopan) sustained clinically meaningful results at one year in Phase III C3 glomerulopathy (C3G) trial

New APPEAR-C3G data show Fabhalta sustained proteinuria reduction at 12 months1 Upon Fabhalta initiation, improvement observed in estimated glomerular filtration rate (eGFR) slope – a key measure of kidney function – vs. patients' historic rapid decline1 Fabhalta also showed a favorable safety profile with no new safety signals1 Fabhalta is the only oral alternative complement pathway inhibitor to selectively target the underlying cause of C3G, an ultra-rare kidney disease with no approved treatments2-5 Novartis continues to advance multi-asset renal portfolio; C3G regulatory submissions completed in EU, China and Japan, and expected in US by year-end EAST HANOVER, N.J., Oct. 26, 2024 /PRNewswire/ -- Novartis today presented 12-month data from the Phase III APPEAR-C3G study at American Society of Nephrology (ASN) Kidney Week 2024 showing that patients with C3 glomerulopathy (C3G) treated with oral Fabhalta® (iptacopan) in addition to supportive care experienced clinically meaningful, sustained results at one year.1 These data confirm treatment with Fabhalta resulted in clinically meaningful proteinuria reduction, which was seen as early as 14 days, and sustained at 12 months. Similarly, in an open-label period of the study, proteinuria reduction was seen in participants who were switched to Fabhalta. In addition, improvement in estimated glomerular filtration rate (eGFR) slope was observed upon Fabhalta initiation compared to patients' historic rapid decline based on results from a prespecified exploratory analysis. Fabhalta showed a favorable safety profile, with no new safety signals.1 APPEAR-C3G evaluated the efficacy and safety of twice-daily oral Fabhalta in adult patients with C3G. The study was comprised of a 6-month randomized, double-blind treatment period with Fabhalta compared to placebo, followed by an additional 6-month open-label treatment period where all participants received Fabhalta.1 Results previously presented at the 2024 European Renal Association (ERA) Congress demonstrated a statistically significant and clinically meaningful 35.1% proteinuria reduction vs. placebo on top of supportive care at 6 months.6 Longer-term data show sustained results with oral Fabhalta "As a clinician treating young people living with C3G, I see firsthand the challenges with therapies used to treat this condition today, underscoring the vital need for dedicated treatment for these patients," said Carla Nester, M.D., M.S.A., F.A.S.N., Professor of Pediatrics-Nephrology at the University of Iowa and APPEAR-C3G Co-Investigator. "I am encouraged to see these data, which reinforce the clinically meaningful impact on kidney health measures we saw at 6 months. As the only oral complement inhibitor intended to treat C3G, Fabhalta could provide new hope for people living with this condition." "These results mark an important milestone for the management of C3G, as the first study to shed light on longer-term treatment targeting the underlying mechanism of this disease via the alternative complement pathway," said Andrew Bomback, M.D., M.P.H., Associate Professor of Medicine at Columbia University Irving Medical Center and APPEAR-C3G Co-Investigator and Steering Committee Member. "I am optimistic that these iptacopan APPEAR-C3G findings bring us a step closer to revolutionizing the treatment paradigm in this ultra-rare disease with no approved therapies." Approximately 50% of C3G patients progress to kidney failure within 10 years of diagnosis, at which point they require lifelong dialysis and/or kidney transplantation.4,7 Fabhalta, the only oral Factor B inhibitor of the alternative complement pathway, has potential to be the first US Food and Drug Administration (FDA) approved treatment for C3G.2,4,5 Regulatory submissions for Fabhalta in C3G are completed in the EU, China and Japan, and expected in US by year-end. Transforming patient care in kidney disease "We are thrilled to share these data, which demonstrate the potential of Fabhalta in C3G, and look forward to working with regulatory authorities with the goal of bringing this innovative medicine to this patient community," said David Soergel, M.D., Global Head, Cardiovascular, Renal and Metabolism Development Unit, Novartis. "Building on the longstanding experience of Novartis in nephrology and our first rare kidney disease approval in IgA nephropathy earlier this year, these results in C3G show continued advancement of our broad, industry-leading portfolio, which aims to transform care for these patients." Fabhalta, discovered at Novartis, received FDA approval in December 2023 for the treatment of adults with paroxysmal nocturnal hemoglobinuria (PNH) and accelerated approval in August 2024 for the reduction of proteinuria in certain adults with primary IgA nephropathy (IgAN).2 Fabhalta is being studied in a broad range of rare kidney diseases, including C3G, atypical hemolytic uremic syndrome (aHUS), immune complex membranoproliferative glomerulonephritis (IC-MPGN) and lupus nephritis (LN). Studies are ongoing to evaluate the safety and efficacy profiles in these investigational indications and support potential regulatory submissions. In addition to Fabhalta, Novartis is advancing the late-stage development of two additional IgAN therapies with highly differentiated mechanisms of action: atrasentan, an investigational oral endothelin A receptor antagonist that received FDA filing acceptance in Q2 2024, and zigakibart, an investigational subcutaneously administered anti-APRIL monoclonal antibody that is currently in Phase III development. A conference call to update investors on the Novartis renal portfolio will take place on Monday, October 28, 2024, at 8:00 am ET. Details can be found at Event calendar | Novartis. About APPEAR-C3G APPEAR-C3G (NCT04817618) is a Phase III multicenter, randomized, double-blind, parallel group, placebo-controlled study to evaluate the efficacy and safety of twice-daily oral Fabhalta (200 mg) in C3G patients. The study comprises a 6-month double-blind period in which adult patients were randomized 1:1 to receive Fabhalta or placebo on top of supportive care, followed by a 6-month open-label period in which all patients receive Fabhalta (including those who were previously on placebo). The primary endpoint for the double-blind period was proteinuria reduction from baseline at 6 months for Fabhalta compared to placebo as measured by 24-hour urine protein to creatinine ratio (UPCR).1,8 In addition to the results from adult patients with C3G, enrollment is ongoing in a separate cohort of adolescent patients with C3G.8 The majority of treatment-emergent adverse events (TEAEs) over the 12-month study period were mild to moderate in severity and there were no deaths, no cases of meningitis and/or meningococcal sepsis and no discontinuations due to TEAEs.1 About C3 glomerulopathy (C3G) C3G is an ultra-rare, progressive kidney disease that initially presents mostly in children and young adults.3,4,9 Each year, approximately 1-2 people per million worldwide are newly diagnosed with C3G, a form of membranoproliferative glomerulonephritis (MPGN).3 In C3G, overactivation of the alternative complement pathway – part of the immune system – causes deposits of C3 protein to build up in kidney glomeruli, which are a network of blood vessels that filter waste and remove extra fluids from the blood.9,10 This triggers inflammation and glomerular damage that results in proteinuria (protein in urine), hematuria (blood in urine) and reduced kidney function.9,11 Indication FABHALTA® (iptacopan) is a prescription medicine used to reduce protein in the urine (proteinuria) in adults with primary immunoglobulin A nephropathy (IgAN), who are at risk of their disease progressing quickly. It is not known if FABHALTA is safe and effective in children with IgAN. FABHALTA has been approved based on a reduction of proteinuria. Continued approval may require results from an ongoing study to determine whether FABHALTA slows decline in kidney function. Important Safety Information FABHALTA is a medicine that affects part of the immune system and may lower one's ability to fight infections. FABHALTA increases the chance of getting serious infections caused by encapsulated bacteria, including Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae type b. These serious infections may quickly become life-threatening or fatal if not recognized and treated early. Patients must complete or update vaccinations against Streptococcus pneumoniae and Neisseria meningitidis at least 2 weeks before the first dose of FABHALTA. If patients have not completed vaccinations and FABHALTA therapy must be started right away, they should receive the required vaccinations as soon as possible. If patients have not been vaccinated and FABHALTA must be started right away, they should also receive antibiotics to take for as long as their doctor tells them. If patients have been vaccinated against these bacteria in the past, they might need additional vaccinations before starting FABHALTA. Their doctor will decide if they need additional vaccinations. Vaccines do not prevent all infections caused by encapsulated bacteria. Patients should call their doctor or get emergency medical care right away if they have any of these signs and symptoms of a serious infection: fever with or without shivers or chills, fever with chest pain and cough, fever with high heart rate, headache and fever, confusion, clammy skin, fever and a rash, fever with breathlessness or fast breathing, headache with nausea or vomiting, headache with stiff neck or stiff back, body aches with flu-like symptoms, or eyes sensitive to light. Doctors will give their patients a Patient Safety Card about the risk of serious infections. Patients must carry it with them at all times during treatment and for 2 weeks after their last dose of FABHALTA. The risk of serious infections may continue for a few weeks after their last dose of FABHALTA. It is important for patients to show this card to any doctor who treats them. This will help doctors diagnose and treat patients quickly. FABHALTA is only available through a program called the FABHALTA Risk Evaluation and Mitigation Strategy (REMS). Before patients can take FABHALTA, their doctor must enroll in the FABHALTA REMS program, counsel patients about the risk of serious infections caused by certain bacteria, give patients information about the symptoms of serious infections, make sure that patients are vaccinated against serious infections caused by encapsulated bacteria and that they receive antibiotics if they need to start FABHALTA right away and are not up to date on vaccinations, as well as give patients a Patient Safety Card about the risk of serious infections. Patients should not take FABHALTA if they are allergic to FABHALTA or any of the ingredients in FABHALTA. Patients should not take FABHALTA if they have a serious infection caused by encapsulated bacteria, including Streptococcus pneumoniae, Neisseria meningitidis, or Haemophilus influenzae type b when starting FABHALTA. Before taking FABHALTA, patients should tell their doctor about all their medical conditions, including if they have an infection or fever, have liver problems, are pregnant or plan to become pregnant (it is not known if FABHALTA will harm an unborn baby), or are breastfeeding or plan to breastfeed as it is not known if FABHALTA passes into breast milk. Patients should not breastfeed during treatment and for 5 days after the final dose of FABHALTA. Patients should tell their doctor about all the medicines they take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Taking FABHALTA with certain other medicines may affect the way FABHALTA works and may cause side effects. Patients should know the medicines they take and the vaccines they receive. Patients should keep a list of them to show their doctor and pharmacist when they get a new medicine. FABHALTA may cause serious side effects, including those mentioned above as well as increased cholesterol and triglyceride (lipid) levels in the blood. Doctors will do blood tests to check patients' cholesterol and triglycerides during treatment with FABHALTA. Doctors may start patients on medicine to lower cholesterol if needed. The most common side effects of FABHALTA in adults include headache; nasal congestion, runny nose, cough, sneezing, and sore throat (nasopharyngitis); diarrhea; pain in the stomach (abdomen); infections (bacterial and viral); nausea; and rash.

Purespring Therapeutics has secured £80m ($105m) to kick start a Phase I/II trial of its experimental adeno-associated viral (AAV) gene therapy in a kidney disease. The London-based biotech’s lead asset PS-002 will be investigated for IgA nephropathy (IgAN), an autoimmune and kidney disease where too much immunoglobulin A (IgA) protein stays in the kidneys. The condition causes inflammation and can lead to end-stage renal disease. PS-002 is an experimental AAV gene therapy designed to target podocytes, specialised cells critical for proper kidney function. In IgAN, immune complexes damage these cells, leading to protein leakage and kidney dysfunction. Purespring’s portfolio also includes a programme targeting nephrotic syndrome, named PS-001, and another focused on an undisclosed glomerular kidney disease programme. Purespring showcased preclinical data of its PS-001 therapy at the European Renal Association (ERA) Congress in May 2024. The data showed that transgenes can be efficiently targeted to podocytes to replace defective genes or to use the podocyte as a protein factory to modulate kidney biology. The Series B funding round was led by Sofinnova Partners in collaboration with Gilde Healthcare, Forbion, British Patient Capital and founding investor Syncona . Purespring launched out of Syncona in 2021 with $45m Series A funding under its belt. The company has a ‘gene search engine’ platform, dubbed FunSel, which selects the most effective treatments for diseases from a large library of AAV vectors, without focusing on specific genes or mechanisms.

In August 2023, pharma giant Novartis bought Chinook Therapeutics in a $3.2bn deal where it acquired two drugs, atrasentan and zigakibart. Both candidates are currently being investigated in Phase III clinical trials for IgAN (NCT04573478 and NCT05852938). Vertex Pharmaceuticals and Biogen followed suit, inking deals with Alpine Immune Sciences and Human Immunology Biosciences, respectively. The deals, both worth more than $1bn, saw the companies inherit assets set to treat IgAN. In the announcement accompanying the funding, Purespring’s CEO Julian Hanak said: “Nearly one-tenth of the world’s population, around 840 million people, suffer from chronic kidney disease. For many of them, there are few options beyond dialysis and transplantation. Our novel treatment platform and deep understanding of kidney disease puts us in a position to stop, reverse and even cure kidney disease. The funds raised will allow us to bring our novel treatments to patients in the clinic.” Cell & Gene Therapy coverage on Pharmaceutical Technology is supported by Cytiva .
