Ciliopathies

PHOENIX, Oct. 30, 2024 (GLOBE NEWSWIRE) -- A Race Against Blindness, a nonprofit organization dedicated to funding sight-saving research for children, is pleased to announce a $1 million grant to Axovia Therapeutics to support the company’s lead program, AXV-101. This marks an important step toward developing a treatment to address blindness and obesity associated with Bardet-Biedl Syndrome 1 (BBS1), a rare genetic disorder with no current curative options. The funding from A Race Against Blindness will directly support Axovia's near-term milestones associated with the initiation of the clinical study and initial patient enrollment in the United Kingdom in mid-2025 to treat blindness caused by BBS1 mutations. Axovia Therapeutics’ future plans include initiation of a clinical trial in the United States and progression of the program to also treat obesity. BBS is a devastating genetic disorder associated with primary cilia dysfunction. One of the hallmarks is retinal degeneration commonly presenting as retinitis pigmentosa. The other hallmark is hyperphagia resulting in morbid obesity, among other complex clinical manifestations. Of the many genes known to be associated with BBS, pathogenic variants in the BBS1 gene are most commonly encountered. Axovia is developing a genetic therapy for those harboring two mutations in the BBS1 gene. There is no cure for BBS, and its prevalence ranges between one in 70,000 and one in 100,000 in Europe and North America, with up to 10 times this prevalence in the Middle East. “Our $1 million grant to Axovia is a significant step for the BBS community, and we are optimistic about Axovia’s groundbreaking clinical research. However, the path to treating RP/BBS is challenging and there is still much work to be done. A Race Against Blindness is committed to supporting the effort to raise the necessary funds to ensure the execution of the AXV-101 clinical trial and potentially bring a new therapeutic option to BBS patients like our son, Luke,” said Dr. Stephen Johnston, Co-Founder and President. “We are advancing the AXV-101 program and preparing to initiate the first clinical study in mid-2025. We are immensely grateful for this funding from A Race Against Blindness,” said Professor Phil Beales, Chief Executive Officer and Co-Founder at Axovia Therapeutics. “By utilizing gene therapy to address the loss of sight and obesity experienced by patients with BBS1, we believe our approach will have a profound and dramatic impact on the health and well-being of this community. We look forward to generating clinical data for this program.” With the goal of initiating clinical studies in mid-2025, A Race Against Blindness will continue aggressive efforts to fundraise, engage the scientific community, and raise global awareness of BBS.

In first dedicated study of a selective IL-13 inhibitor in patients previously treated with dupilumab, the majority of patients had a history of inadequate response to dupilumab EBGLYSS also provided meaningful improvements in difficult-to-treat face and hand dermatitis The safety profile of EBGLYSS was consistent with previous Phase 3 studies and of the patients who reported eye-related events, facial dermatitis or inflammatory arthritis as the reason for prior dupilumab discontinuation, none reported similar events with EBGLYSS INDIANAPOLIS, Oct. 25, 2024 /PRNewswire/ -- New results show Eli Lilly and Company's (NYSE: LLY) EBGLYSS improved skin (including hand and face) and itch among patients with moderate-to-severe atopic dermatitis (eczema) who were previously treated with dupilumab. These results from the Phase 3b ADapt study will be presented at the Fall Clinical Dermatology (FCD) Conference from Oct. 24-27 in Las Vegas.1 EBGLYSS is an interleukin-13 (IL-13) inhibitor that selectively blocks IL-13 signaling with high binding affinity.2,3,4 The cytokine IL-13 is key in atopic dermatitis, driving the type-2 inflammatory cycle in the skin, leading to skin barrier dysfunction, itch, skin thickening and infection.5,6 "Treatment isn't one-size-fits-all, and many patients with moderate-to-severe atopic dermatitis remain in need of an effective medicine to help manage the impact of the disease, especially in difficult-to-treat areas like face and hands," said Linda Stein Gold, M.D., investigator of the ADapt study, director of dermatology research and head of the Division of Dermatology for Henry Ford Health System in Detroit, Michigan. "These data showed that EBGLYSS improved skin symptoms and reduced itch for the majority of patients who had stopped using dupilumab and complement previously presented EBGLYSS data in biologic-naive patients, further supporting that a broad range of patients could benefit from this new and effective treatment option." The ADapt study evaluated the efficacy and safety of EBGLYSS in patients with moderate-to-severe atopic dermatitis who were previously treated with dupilumab. To qualify for ADapt, patients must have discontinued dupilumab treatment due to inadequate response, intolerance or an adverse event, or other reasons (including cost or loss of access to the medicine). View an EBGLYSS patient photo from the ADapt study here.1 The primary endpoint of the study was measured by at least 75 percent improvement in the Eczema Area and Severity Index (EASI-75) score at 16 weeks, which evaluates the extent and severity of the skin disease. Secondary endpoints at 16 and 24 weeks included Investigator Global Assessment (IGA) score of clear (0) or almost clear (1) skin with a reduction of at least two points from baseline and at least a four-point improvement in Pruritus NRS from baseline. Other secondary and exploratory endpoints were also included.1 The reported endpoints were as observed. With EBGLYSS, 57 percent of patients at Week 16, and 60 percent of patients at Week 24 who were previously treated with dupilumab, achieved EASI-75. These results are similar to what was observed in the Phase 3 monotherapy trials of EBGLYSS in patients without prior exposure to dupilumab (ADvocate 1 and ADvocate 2). In addition, 46 percent of patients who were inadequate responders to dupilumab achieved EASI-75 response with EBGLYSS at Week 16.1 Fifty-three percent and 62 percent of ADapt patients who discontinued dupilumab and began treatment with EBGLYSS also experienced itch relief (Pruritus NRS) with at least a four-point improvement from baseline at Week 16 and Week 24 respectively.1 Patients in this study saw improvements in difficult-to-treat areas when treated with EBGLYSS. More than half of patients (52 percent) treated with EBGLYSS saw clear or almost clear face dermatitis at Week 24 (F-IGA 0,1 with a reduction of at least two points from baseline). Among patients with moderate-to-severe hand dermatitis at baseline (defined as ≥12), patients' modified total lesion symptom score (mTLSS), which measures extent and severity of hand dermatitis, decreased by 75 percent at Week 24.1* Less than six percent of patients treated with EBGLYSS experienced an adverse event that led to treatment discontinuation.1 The safety profile of EBGLYSS in ADapt was consistent with previous EBGLYSS Phase 3 studies in patients with moderate-to-severe atopic dermatitis, and no new safety signals were observed. The majority of adverse events were mild or moderate. Reported treatment-related side effects in the study were conjunctivitis and injection site reactions. Of the 14 patients who discontinued dupilumab due to an adverse event, two patients discontinued EBGLYSS due to an adverse event. Of the 10 patients who discontinued dupilumab due to eye-related events, facial dermatitis or inflammatory arthritis, none reported similar events with EBGLYSS.1 "This trial supports the growing body of data showing that health care providers can have confidence prescribing EBGLYSS as a first-line biologic treatment for moderate-to-severe atopic dermatitis, and reinforces that EBGLYSS provided a meaningful benefit among individuals who have already tried another biologic treatment such as dupilumab and may have more difficult-to-treat disease," said Mark Genovese, M.D., senior vice president of Lilly Immunology development. Lilly will also present additional data at the Fall Clinical Dermatology conference, including new analyses from the ADjoin long-term extension study with data up to three years. EBGLYSS was approved in the U.S. by the Food and Drug Administration (FDA) last month as a first-line biologic treatment for adults and children 12 years of age and older who weigh at least 88 pounds (40 kg) with moderate-to-severe atopic dermatitis that is not well controlled with topical prescription therapies. EBGLYSS 250 mg/2 mL injection is dosed as a single monthly maintenance injection following the initial phase of treatment. The recommended initial starting dose of EBGLYSS is 500 mg (two 250 mg injections) at Week 0 and Week 2, followed by 250 mg every two weeks until Week 16 or later when adequate clinical response is achieved; after this, maintenance dosing is a single monthly injection (250 mg every four weeks).1 EBGLYSS was also approved in the European Union in 2023, as well as in Japan in January 2024, with additional markets expected later this year. Lilly has exclusive rights for development and commercialization of EBGLYSS in the U.S. and the rest of the world outside Europe. Lilly's partner Almirall S.A. has licensed the rights to develop and commercialize EBGLYSS for the treatment of dermatology indications, including eczema, in Europe. *mTLSS is a composite measure of intensity of seven hand dermatitis signs and symptoms (erythema, edema, desquamation, fissures, hyperkeratosis/lichenification, pruritus/pain, and vesiculation, with total scores ranging from 0 to 21), used to assess improvement in hand dermatitis. About ADapt ADapt (NCT05369403), is an open-label, Phase 3b, 24-week study that evaluated the efficacy and safety of EBGLYSS in adults and adolescents (12 to less than 18 years of age and weighing ≥40 kg) with moderate-to-severe atopic dermatitis who were previously treated with dupilumab. Four or more weeks after discontinuing dupilumab, patients were treated with EBGLYSS and received a starting dosing of 500 mg (two 250 mg injections) at Week 0 and Week 2, followed by 250 mg every two weeks until Week 16. IGA 0,1 or EASI-75 responders at Week 16 received 250 mg once monthly and non-responders continued on 250 mg every two weeks until Week 24. Patients were allowed to stay on low and mid-potency topical corticosteroids.1 From baseline to Week 16, data from the ADapt study was analyzed as observed and with non-responder imputation/multiple imputation (NRI/MI). After Week 16, Q2W and Q4W data from the ADapt study were pooled and analyzed as observed and with NRI/MI.1 INDICATION AND SAFETY SUMMARY EBGLYSS™ (EHB-glihs) is an injectable medicine used to treat adults and children 12 years of age and older who weigh at least 88 pounds (40 kg) with moderate-to-severe eczema (atopic dermatitis) that is not well controlled with prescription therapies used on the skin (topical), or who cannot use topical therapies. EBGLYSS can be used with or without topical corticosteroids. It is not known if EBGLYSS is safe and effective in children less than 12 years of age or in children 12 years to less than 18 years of age who weigh less than 88 pounds (40 kg).

About EBGLYSS EBGLYSS is a monoclonal antibody that selectively targets and neutralizes IL-13 with high binding affinity and a slow dissociation rate.3,4,7 EBGLYSS binds to the IL-13 cytokine at an area that overlaps with the binding site of the IL-4Rα subunit of the IL-13Rα1/IL-4Rα heterodimer, preventing formation of this receptor complex and inhibiting IL-13 signaling. IL-13 is implicated as a primary cytokine tied to the pathophysiology of eczema, driving the type-2 inflammatory loop in the skin, and EBGLYSS selectively targets IL-13.7 The EBGLYSS Phase 3 program consists of five key global studies evaluating over 1,300 patients, including two monotherapy studies (ADvocate 1 and 2), a combination study with topical corticosteroids (ADhere), as well as long-term extension (ADjoin) and adolescent open label (ADore) studies. Further data results from ADjoin and ADmirable are expected to be shared in 2024 and early 2025.

- New data on povetacicept 80 mg SC Q4 weeks in IgA nephropathy shows mean UPCR reduction from baseline of 66% observed at 48 weeks, associated with stable renal function (eGFR) and 63% achieving clinical remission -- - First proteinuria data on povetacicept in primary membranous nephropathy shows mean UPCR reduction from baseline of 62% at 24 weeks – - Global Phase 3 RAINIER trial of povetacicept in IgA nephropathy now underway – – Enrollment and dosing ongoing in Phase 3 portion of the global Phase 2/3 pivotal clinical trial of inaxaplin for the treatment of APOL1-mediated kidney disease – BOSTON--(BUSINESS WIRE)-- Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today provided updates on multiple kidney diseases in its pipeline including IgA nephropathy (IgAN), primary membranous nephropathy (pMN), and APOL1-mediated kidney disease (AMKD). These updates demonstrate the transformative potential of Vertex’s investigational therapies in multiple serious kidney diseases, and include positive new data on povetacicept, a dual inhibitor of the BAFF and APRIL pathways, in IgAN and pMN, presented at the American Society of Nephrology’s (ASN) Kidney Week Congress on October 23-27 in San Diego, California. “We are very pleased with the broadening of our innovative pipeline in renal medicine which now spans programs in AMKD, IgAN, pMN and polycystic kidney disease,” said Carmen Bozic, M.D., Executive Vice President, Global Medicines Development and Medical Affairs, and Chief Medical Officer at Vertex. “The new data in IgAN and pMN we shared at this year’s ASN congress continue to reinforce povetacicept as a potential best-in-class therapy and demonstrate its potential as a pipeline-in-a-product. We also continue to make progress in AMKD and autosomal dominant polycystic kidney disease (ADPKD) where we are advancing the first potential treatments to address the underlying cause of these diseases.” Povetacicept in IgAN Vertex presented data on 54 patients with IgAN who received povetacicept 80 mg or 240 mg subcutaneously every 4 weeks (SC Q4W). Treatment with povetacicept 80 mg SC Q4W demonstrated a clinically meaningful decrease in proteinuria, with a mean 66% reduction from baseline in urine protein to creatinine ratio at 48 weeks (UPCR; n=8) associated with stable renal function over 48 weeks as assessed by estimated glomerular filtration rate (eGFR). By 48 weeks, 63% (5 out of 8) of study participants achieved clinical remission, defined as UPCR 50% reduction in UPCR from baseline. Anti-PLA2R1 autoantibodies, which are a marker of disease activity and associated with clinical outcomes, decreased from baseline by a mean of 87% at week 20. Povetacicept was well tolerated in patients with pMN, with AEs that were mild or moderate in severity. There were no SAEs related to povetacicept. A poster presentation #TH-PO589 entitled “Updated Results with Povetacicept, an Enhanced Dual BAFF/APRIL Antagonist, in Primary Membranous Nephropathy (RUBY-3 Study)” was presented during the poster session on October 24 from 10:00 a.m. to 12:00 p.m. PDT. AMKD Vertex is developing inaxaplin, a potential first-in-class, investigational, oral small molecule inhibitor of APOL1, with the goal of targeting the underlying cause of AMKD. Enrollment and dosing are ongoing in the Phase 3 portion of the global Phase 2/3 pivotal AMPLITUDE clinical trial of inaxaplin. Vertex has the following AMKD poster presentations at ASN: Poster presentation #TH-P01203 entitled “AMPLITUDE: A Phase 2/3 Adaptive Trial of Inaxaplin in APOL1-mediated Kidney Disease” was presented during the poster session on October 24 from 10:00 a.m. to 12:00 p.m. PDT. Poster presentation #SA-PO701 entitled “Small Molecule APOL1 Channel Inhibitor Reduces Proteinuria, Rescues Podocyte Injury, and Reverses eGFR Decline in an APOL1-Mediated Kidney Disease Mouse Model” will be presented during the poster session on October 26 from 10:00 a.m. to 12:00 p.m. PDT. Poster presentation #SA-PO700 entitled “Small Molecule Inhibition of APOL1 Channel Activity Protects Podocytes from Mitochondrial Dysfunction, Cell Death and Barrier Disruption Induced by APOL1 Risk Variants” will be presented during the poster session on October 26 from 10:00 a.m. to 12:00 p.m. PDT. All accepted abstracts are available online on the ASN website . About IgA Nephropathy (IgAN) IgAN is a serious, progressive, life-threatening, B cell-mediated chronic kidney disease that is the most common cause of primary (idiopathic) glomerulonephritis, affecting people worldwide including approximately 130,000 people in the U.S. IgAN results from deposition of circulating immune complexes consisting of immunoglobulins and galactose-deficient immunoglobulin A (Gd-IgA1) in the renal glomerular mesangium, triggering kidney injury and fibrosis. A high percentage of people with IgAN progress to end-stage renal disease. There are no approved therapies that specifically target the underlying cause of IgAN. About RAINIER RAINIER is a global Phase 3 pivotal trial of povetacicept 80 mg vs. placebo on top of standard of care in approximately 480 people with IgAN. The study is designed to have a pre-planned interim analysis evaluating UPCR for the povetacicept arm versus placebo after a certain number of patients reach 36 weeks of treatment. If positive, the interim analysis may serve as the basis for Vertex to seek accelerated approval in the U.S. Final analysis will occur at two years of treatment, with a primary endpoint of total eGFR slope through Week 104. About Primary Membranous Nephropathy (pMN) Primary membranous nephropathy is a serious, progressive, life-threatening B cell-mediated chronic kidney disease affecting people worldwide, with approximately 60,000 people diagnosed in the U.S. pMN causes a patient’s immune system to damage the glomeruli and may cause progressive loss of kidney function. There are no approved therapies that specifically target the underlying cause of pMN. About RUBY-3 RUBY-3 is an ongoing, multiple ascending dose, multi-cohort, open label, Phase 1/2 basket study of povetacicept in autoimmune glomerulonephritis, including IgAN, pMN, lupus nephritis and ANCA-associated vasculitis with glomerulonephritis where povetacicept is being administered subcutaneously for up to 104 weeks. About Povetacicept Povetacicept is a dual antagonist of the BAFF (B cell activating factor) and APRIL (a proliferation inducing ligand) cytokines, which play key roles in pathogenesis of multiple autoimmune diseases via their roles in the activation, differentiation and/or survival of B cells, T cells and innate immune cells. Based upon an engineered TACI (transmembrane activator and CAML interactor) domain, povetacicept has higher binding affinity and greater potency in preclinical studies versus other inhibitors of BAFF and/or APRIL alone and has demonstrated potential best-in-class efficacy in a clinical trial in patients with IgA nephropathy and primary membranous nephropathy. Povetacicept is also in development for multiple serious diseases including other autoimmune kidney diseases and autoimmune cytopenias. About APOL1-Mediated Kidney Disease (AMKD) AMKD is a genetic kidney disease affecting approximately 100,000 people in the U.S. and Europe. AMKD is caused by two variants of the APOL1 gene, which exert a toxic effect on kidney cells, leading to cell injury, cell death and damage to glomeruli (which filter blood to the kidney). Even after treatment with currently available therapies, people with AMKD often progress to kidney failure. Kidney failure is treated with frequent, long-term dialysis or a kidney transplant. Both require lifelong treatment and follow-up and carry a high mortality risk . There are currently no approved treatments that address the underlying cause of AMKD. About Inaxaplin Inaxaplin is a potential first-in-class, investigational small molecule inhibitor of APOL1, and the first investigational therapy aimed at treating the underlying cause of AMKD. About AMPLITUDE AMPLITUDE is a global Phase 2/3 pivotal trial of inaxaplin for the treatment of AMKD, in which a 45 mg once daily oral dose is compared to placebo, on top of standard of care. The study is designed to have a pre-planned interim analysis at Week 48 evaluating estimated glomerular filtration rate (eGFR) slope, a measure of kidney function, supported by a percent change from baseline in proteinuria, in the inaxaplin arm versus placebo. If positive, the interim analysis may serve as the basis for Vertex to seek accelerated approval in the U.S. Enrollment and dosing are ongoing in the Phase 3 portion of the study. About Autosomal Dominant Polycystic Kidney Disease (ADPKD) ADPKD is the most common inherited kidney disease and one of the most common severe Mendelian genetic diseases, affecting approximately 250,000 diagnosed people in the U.S. and Europe. As an autosomal dominant disease, one affected parent can pass on the disease to their children. In most cases, ADPKD is caused by variants in the PKD1 and PKD2 genes, which express proteins known as polycystins. The majority of ADPKD patients (~80%) have a variant in the PKD1 gene, resulting in a loss of function of polycystin 1 (PC1). This leads to the proliferation of kidney epithelial cells, increased fluid secretion and the formation and expansion of numerous fluid-filled cysts. The progressive cyst formation causes an increase in kidney size and decline in kidney function. Around half of patients with ADPKD experience kidney failure by the age of 60. Kidney cysts can also lead to severe abdominal pain, cyst infection, blood in the urine and kidney stones, all of which significantly impair quality of life.
