Indication

TARPEYO is indicated to reduce the loss of kidney function in adults with primary immunoglobulin A nephropathy (IgAN) who are at risk for disease progression.

Important Safety Information

Contraindications: 

TARPEYO is contraindicated in patients with hypersensitivity to budesonide or any of the ingredients of TARPEYO. Serious hypersensitivity reactions, including anaphylaxis, have occurred with other budesonide formulations.

Warnings and Precautions

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).

Risks of immunosuppression:

Patients who are on drugs that suppress the immune system are more susceptible to infection than healthy individuals. Chickenpox and measles, for example, can have a more serious or even fatal course in susceptible patients or patients on immunosuppressive doses of corticosteroids. Avoid corticosteroid therapy in patients with active or quiescent tuberculosis infection; untreated fungal, bacterial, systemic viral, or parasitic infections, or ocular herpes simplex. Avoid exposure to active, easily-transmitted infections (e.g., chickenpox, measles). Corticosteroid therapy may decrease the immune response to some vaccines.

Other corticosteroid effects: 

TARPEYO is a systemically available corticosteroid and is expected to cause related adverse reactions. Monitor patients with hypertension, prediabetes, diabetes mellitus, osteoporosis, peptic ulcer, glaucoma or cataracts, or with a family history of diabetes or glaucoma, or with any other condition where corticosteroids may have unwanted effects.

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%).

Drug interactions: 

Budesonide is a substrate for CYP3A4. Avoid use with potent CYP3A4 inhibitors, such as ketoconazole, itraconazole, ritonavir, indinavir, saquinavir, erythromycin, and cyclosporine. Avoid ingestion of grapefruit juice with TARPEYO. Intake of grapefruit juice, which inhibits CYP3A4 activity, can increase the systemic exposure to budesonide.

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.

NefIgArd is a phase III, 2-year global study in 364 patients with IgAN1

Analyzed a 9-month course of treatment with TARPEYO + RASi vs RASi alone1

The chart describes the efficacy study design of the Tarpeyo phase 3 trial

*Interim analysis primary endpoint: UPCR at 9 months compared to baseline (n=199).

Key inclusion criteria

Adult patients with1,2:

  • Biopsy-confirmed IgAN diagnosis
  • Persistent proteinuria ≥1 g/day or UPCR ≥0.8 g/g in 2 consecutive measurements
  • eGFR 35 to 90 mL/min/1.73 m2
  • Receiving RASi therapy (ACEis and/or ARBs) at the maximum allowed/tolerated dose 3 months prior to randomization

Select secondary efficacy endpoints2:

  • Composite endpoint of time from randomization to confirmed 30% reduction in eGFR (confirmed by 2 values over ≥4 weeks)
  • Ratios of UPCR and UACR compared with baseline†
  • Proportion of patients without microhematuria during observational follow-up
Blood pressure and diabetes were well controlled and no prophylaxis with antibiotics was required1,2

NefIgArd trial was designed to evaluate kidney function at 2 years after
9 months on treatment with TARPEYO, as measured by eGFR1

†Ratios were averaged over timepoints between 12 and 24 months, inclusive, after the first dose of study drug.2

ACEi=angiotensin-converting enzyme inhibitor; ARB=angiotensin II receptor blocker; eGFR=estimated glomerular filtration rate; RASi=renin-angiotensin system inhibitor; UACR=urine albumin-creatinine ratio; UPCR=urine protein-to-creatinine ratio.

TARPEYO was studied under the name NEFECON.

Select baseline characteristics2,7

The chart describes the efficacy study design of the Tarpeyo phase 3 trial
  • More than half of patients were younger than 45 years of age at study entry2
  • Diverse patient population across ethnic backgrounds2
  • Blood pressure was well controlled at study entry (recommended target of <125/75 mmHg)2
  • Majority of patients had not been on prior steroid therapy2

    On average, patients at baseline were only 2.5 years
    post IgAN diagnosis and already at Stage 3 CKD2

    CKD=chronic kidney disease.
