STOCKHOLM, April 18, 2024 /PRNewswire/ --
today announced additional data analyses from the 2-year Phase 3 NeflgArd trial evaluating Nefecon (TARPEYO® (budesonide) delayed-release capsules/Kinpeygo®) in patients with IgA nephropathy (IgAN), were presented at the ISN World Congress of Nephrology in Buenos Aires, Argentina on April 13-16, 2024. "We were pleased to share additional analyses from the 2-year Phase 3 NeflgArd trial of Nefecon in IgAN at this year's World Congress of Nephrology," said Richard Philipson, Chief Medical Officer of Calliditas. "These additional data further reinforce the impact of Nefecon across the entire study population, irrespective of baseline UPCR levels or patient's racial and ethnic backgrounds." Poster presentation details are below and will be available on the Presentations and Publications page on the Calliditas' corporate website following the meeting. Poster Presentation Analyses:
Poster Title: "Nefecon treatment provides kidney benefits for patients with IgAN that extend to those with low levels of UPCR: A sub-analysis of the phase III NefIgArd trial" An extended analysis of patients with baseline UPCR levels above and below 0.8 g/g was performed to further explore the potential benefits of Nefecon. In the full analysis involving 364 patients regardless of baseline UPCR, Nefecon treatment consistently improved the estimated glomerular filtrate rate (eGFR) over the 2-year study period compared to placebo. 72 patients with a baseline UPCR 1.73 m2 per year, indicating that Nefecon treatment may support them in reaching the RaDaR treatment target of an eGFR decline of 1.73 m2 in Asian patients and 4.8 mL/min/1.73 m2 in White patients. Nefecon also demonstrated greater reductions in UPCR at 9 and 24 months with notable delays in kidney function decline events. These effects were consistent across races and ethnicities. Additionally, Nefecon significantly reduced the rate of microhematuria in both Asian and White patients. Overall, these findings highlight Nefecon's efficacy and tolerability across different racial and ethnic groups. Important Safety Information
Hypercorticism and adrenal axis suppression: When corticosteroids are used chronically, systemic effects such as hypercorticism and adrenal suppression may occur. Corticosteroids can reduce the response of the hypothalamus-pituitary-adrenal (HPA) axis to stress. In situations where patients are subject to surgery or other stress situations, supplementation with a systemic corticosteroid is recommended. When discontinuing therapy or switching between corticosteroids, monitor for signs of adrenal axis suppression. Patients with moderate to severe hepatic impairment (Child-Pugh Class B and C respectively) could be at an increased risk of hypercorticism and adrenal axis suppression due to an increased systemic exposure to oral budesonide. Avoid use in patients with severe hepatic impairment (Child-Pugh Class C). Monitor for increased signs and/or symptoms of hypercorticism in patients with moderate hepatic impairment (Child-Pugh Class B). Adverse reactions: In clinical studies, the most common adverse reactions with TARPEYO (occurring in ≥5% of TARPEYO treated patients, and ≥2% higher than placebo) were peripheral edema (17%), hypertension (12%), muscle spasms (12%), acne (11%), headache (10%), upper respiratory tract infection (8%), face edema (8%), weight increased (7%), dyspepsia (7%), dermatitis (6%), arthralgia (6%), and white blood cell count increased (6%). Use in specific populations
Pregnancy: The available data from published case series, epidemiological studies, and reviews with oral budesonide use in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. There are risks to the mother and fetus associated with IgAN. Infants exposed to in-utero corticosteroids, including budesonide, are at risk for hypoadrenalism. Full Prescribing Information
TARPEYO is an oral 4mg delayed release formulation of budesonide, designed to remain intact until it reaches the ileum. Each capsule contains coated beads of budesonide that target mucosal B-cells present in the ileum, including the Peyer's patches, which are responsible for the production of galactose-deficient IgA1 antibodies (Gd-Ag1) causing IgA nephropathy. NefIgArd was a global, Phase 3, randomized, double-blind, placebo-controlled, multicenter study to evaluate the efficacy and safety of TARPEYO 16 mg once daily vs placebo in adult patients with primary IgAN (N=364) as an addition to optimized RASi therapy. Patients were randomized 1:1 to receive 16 mg/day oral capsules of TARPEYO or matching placebo for 9 months, followed by a 15-month observational follow-up period without the study drug. The primary efficacy endpoint was time-weighted average of eGFR over 2 years. The time-weighted average of eGFR over 2 years showed a statistically significant treatment benefit with TARPEYO versus placebo (difference 5•05 mL/min per 1•73 m² [95% CI 3•24 to 7•38], p[email protected] The information was sent for publication, through the agency of the contact persons set out above, on April 18, 2023, at 13.00 p.m. CET.
