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-C3GAPPEAR-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.
