Why two NDCs? The FDA registers this code as 85052-101-04 — a 5-3-2 layout, and that's what's printed on the package and shown on DailyMed. For insurance claims, every NDC is standardized to a uniform 11-digit 5-4-2 format by adding a zero to the product segment → 85052-0101-04. Same drug, same package — only the format differs.

🧪 Inactive Ingredients / Excipients

Inactive ingredients, also called excipients, are components of the drug product other than the active ingredient. They may include fillers, dyes, coatings, preservatives, flavors, or other formulation ingredients.

A current SPL was checked, but it does not contain a structured or narrative inactive-ingredient list for this product. This does not mean the product has no inactive ingredients.
Where does this data come from?
Source: official FDA Structured Product Labeling (SPL) via DailyMed and the openFDA label index. Structured IACT rows and label-wide narrative are kept separate; availability and product-level specificity depend on the submitted label.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Price systemPer mLPer package
Retail pharmacies payNADAC · weekly Not in the retail survey — common for institutional, discontinued, or low-volume packs.
Medicaid paysCMS SDUD · 12 mo No recent Medicaid claims on file for this NDC — rare and low-volume NDCs are suppressed in the public data.
Medicare drug plans payPart D · quarterly No Part D plan price is available for this NDC in our data.
ℹ️
No price is published for this exact package yet. CMS surveys NADAC per package size, so a different pack of the same drug often has one.
Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The FDA registers it as 85052-101-04, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 85052-0101-04, written without dashes as 85052010104. The Identity section at the top of this page lists every form of this code.
What do the three segments of this NDC mean?
In 85052-0101-04, the first segment (85052) is the labeler code FDA assigned to Vera Therapeutics, Inc; the middle segment (0101) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (04) identifies this exact package size and type. Together they name one specific package of one specific product.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Vera Therapeutics, Inc. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Vera Therapeutics, Inc is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.

⚠️ Warnings and Cautions ~1 min read

5 WARNINGS AND PRECAUTIONS Immunosuppression and Increased Risk of Infections: Delay initiation of TRUTAKNA during an active infection. During treatment, monitor for signs and symptoms of infections and consider interrupting TRUTAKNA if the infection becomes serious. ( 5.1 ) Immunosuppression and Immunization Risks : Live vaccines not recommended within 30 days prior to initiation of TRUTAKNA or during treatment. ( 5.2 )

5.1Immunosuppression and Increased Risk of Infections TRUTAKNA suppresses the immune system by reducing antibody production, which may increase the risk of infections. Patients with a chronic infection or recurring infections may have an increased risk of serious infection. In clinical trials, infections were reported in 32% of patients in the TRUTAKNA group compared with 28% of participants in the placebo group [ see Adverse Reactions ( 6.1 ) ].

Before initiating TRUTAKNA, assess patients for active infections. Delay TRUTAKNA administration in patients with active infection until the infection resolves or is adequately treated. During treatment, monitor patients for signs and symptoms of infection.

If a serious infection develops, consider interrupting TRUTAKNA until the infection is controlled. The concomitant use of TRUTAKNA and other immune-modulating therapies has not been evaluated. Concomitant use of TRUTAKNA with drugs that affect the immune system, including systemic corticosteroids, may increase the risk of infection.

5.2Immunosuppression and Immunization Risks TRUTAKNA may interfere with the immune responses to vaccines and increase the risk of infection from live vaccines. Prior to initiating treatment with TRUTAKNA, complete all age appropriate immunizations according to current immunization guidelines. Live vaccines are not recommended within 30 days prior to initiation of TRUTAKNA or during treatment with TRUTAKNA as safety of coadministration has not been established.

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Immunosuppression and Increased Risk of Infections [see Warnings and Precautions ( 5.1 )] Immunosuppression and Immunization Risks [see Warnings and Precautions ( 5.2 )] The most common adverse reactions with TRUTAKNA (incidence ≥5% and greater than placebo) were upper respiratory tract infection, injection site reaction and injection site erythema. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Vera Therapeutics at 1-833-633-8372 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of TRUTAKNA was evaluated in a randomized, double-blind, placebo-controlled clinical study in 428 adults with IgAN (Origin 3). The median duration of exposure was 34 weeks in the 214 patients treated with TRUTAKNA and 31 weeks in the 214 patients administered placebo [see Clinical Studies ( 14 )] .

The most common adverse reactions (reported in ≥5% of patients treated with TRUTAKNA and at a higher incidence than placebo) in patients treated with TRUTAKNA and placebo, respectively, were infections (32% vs. 28%) and local administration reactions (30% vs. 5%).

The most common infection was upper respiratory tract infection (12% vs. 9%), and the most common local administration reactions were injection site reaction (19% vs. 2%) and injection site erythema (6% vs.

1%). Most adverse reactions observed in the TRUTAKNA group were mild or moderate in severity and resolved without treatment interruption or discontinuation.

8 USE IN SPECIFIC POPULATIONS

8.1Pregnancy Risk Summary Available data on TRUTAKNA use in pregnant women exposed during clinical trials are insufficient to evaluate for a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. Based on mechanism of action, TRUTAKNA may cause immunosuppression in the in utero-exposed infant [see Warnings and Precautions ( 5.1 and 5.2 ), Clinical Pharmacology ( 12.1 ) and Clinical Considerations ] . There are risks to the mother and infant with untreated IgAN nephropathy in pregnancy (see Clinical Considerations ) .

In animal reproduction studies, no treatment-related malformations were observed in mice and rabbits at atacicept-vymj exposures approximately up to 12 times and 4 times, respectively, the clinical exposure at the recommended human dose (RHD) (see Data ). The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of major birth defects, loss, or other adverse outcomes.

In the U.S. general population, the estimated background risk of major birth defects and miscarriages in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Pregnant women exposed to TRUTAKNA, or their healthcare providers, should report TRUTAKNA exposure by calling 1-833-633-8372. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk IgAN in pregnancy is associated with adverse maternal outcomes, including increased rates of cesarean section, pregnancy-induced hypertension, pre-eclampsia and preterm delivery, and adverse fetal/neonatal outcomes, including stillbirth and low birth weight.

Fetal/Neonatal Adverse Reactions Based on mechanism of action, TRUTAKNA may cause immunosuppression in the in utero exposed infant. The potential clinical impact of TRUTAKNA exposure in infants exposed in utero should be considered. Data Animal Data In pregnant mice, SC administration of atacicept-vymj once every two days (0, 5, 20, and 80 mg/kg) throughout organogenesis from gestation day (GD) 6 to 15 did not result in any adverse effects on embryofetal development at up to 80 mg/kg, approximately 12 times the clinical exposure at the RHD based on area under the concentration curve (AUC).

In pregnant rabbits, SC administration of atacicept-vymj once every two days (0, 5, 20, and 80 mg/kg) throughout organogenesis from GD 6 to 18 resulted in early and late resorptions, reduced number of live fetuses, and decreased mean fetal weight at ≥20 mg/kg, doses that resulted in maternal toxicity (reduced body weight gain). Exposures at these doses were ≥4 times the clinical exposure at the RHD, based on AUC. Embryofetal malformations (enlarged bregmatic fontanella, severe reduction of ossification of parietal or frontal bones, and unossified interparietal bones) were observed at 80 mg/kg (maternally toxic dose), approximately 11 times the clinical exposure at the RHD, based on AUC.

No treatment-related malformations were observed at up to 20 mg/kg, approximately 4 times the clinical exposure at the RHD, based on AUC. In a pre- and post-natal development study in mice, SC administration of atacicept-vymj once every two days (0, 5, 20, or 80 mg/kg) throughout pregnancy and lactation (GD 6 to lactation day 21) did not result in adverse effects on maternal function or development of offspring at up to 80 mg/kg, approximately 12 times the clinical exposure at the RHD based on AUC.

8.2Lactation Risk Summary There are no data regarding the presence of atacicept-vymj in human milk, the effects of the drug on the breastfed infant, or the effects of the drug on milk production/excretion. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for TRUTAKNA and any potential adverse effects on the breastfed child from TRUTAKNA or from the underlying maternal condition.

🧬 Clinical Pharmacology ~2 min read

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Atacicept-vymj, a BLyS-specific inhibitor and APRIL blocker, is a TACI-Fc fusion glycoprotein that binds B cell activating factor (BAFF) and APRIL with dissociation constants (Kd) of 106 pM and 33 pM, respectively, and reduces BAFF- and APRIL-mediated signaling. BAFF is also known as BlyS. Reduction in BAFF- and APRIL-mediated signaling decreases production of serum galactose deficient IgA1 (Gd-IgA1), which is implicated in the pathophysiology of IgAN.

12.2Pharmacodynamics Immunoglobulins In IgAN patients treated with TRUTAKNA once weekly in the Origin 3 study, serum Gd-IgA1, Immunoglobulin A (IgA), Immunoglobulin G (IgG), and Immunoglobulin M (IgM) levels decreased within 4 weeks and these reductions were sustained through Week 36. By Week 36, mean serum levels were reduced from baseline by 68% for Gd-IgA1, 64% for IgA, 36% for IgG, and 75% for IgM.

12.3Pharmacokinetics Absorption Following once weekly SC administration of TRUTAKNA 150 mg in IgAN patients, atacicept-vymj pharmacokinetics increased proportionally over a dose range of 75 to 150 mg. Steady state was achieved after approximately 24 weeks. Following the first SC dose, the maximum atacicept-vymj concentrations were reached approximately 36 hours after atacicept-vymj administration.

Distribution Central and peripheral volume of distribution were 44 L and 61 L, respectively, in patients with IgAN. Metabolism/Elimination No drug metabolism studies have been conducted. Atacicept-vymj is a therapeutic protein that is expected to be catabolized into small peptides and amino acids by general catabolic degradation processes in multiple tissues.

The estimated clearance of atacicept-vymj is

3.2L/day, and the elimination half-life is approximately 40 days in IgAN patients. Specific Populations No clinically significant differences in the pharmacokinetics of atacicept-vymj were observed based on sex, age (18 to 74 years), weight (38.4 to 138 kg), race, and mild to severe renal impairment (eGFR: 22 to 89 mL/min).

12.6Immunogenicity The observed incidence of anti-drug antibodies (ADA) is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of ADA in the studies described below with the incidence of ADA in other studies, including those of TRUTAKNA. In a pooled analysis of phase 2 and phase 3 clinical data through Week 36 in patients with primary IgAN, 43.2% (60 of 139) of study subjects who were treated with TRUTAKNA once weekly developed ADA.

There were no clinically significant effects of ADA on the pharmacokinetics, pharmacodynamics, safety or effectiveness of TRUTAKNA over the treatment duration of 36 weeks in these studies.

📋 Description 168 words

11 DESCRIPTION Atacicept-vymj, a B-lymphocyte stimulator (Blys)-specific inhibitor and A Proliferation Inducing Ligand (APRIL) blocker, is a soluble recombinant fusion glycoprotein consisting of two parts: the extracellular ligand binding portion of the human transmembrane activator, calcium modulator, and cyclophilin ligand interactor (TACI) receptor and the Fc portion of human IgG1 (TACI Fc), which has been modified to reduce Fc receptor-mediated effector functions. Atacicept-vymj is produced by recombinant DNA technology in Chinese hamster ovary (CHO) cells.

The molecular weight of atacicept-vymj is 73.5 kDa (kilodaltons) based on the homodimeric form of the protein, which is composed of two identical monomers. TRUTAKNA (atacicept-vymj) injection is supplied as a sterile, preservative-free, clear to slightly opalescent, brownish yellow solution for subcutaneous injection. It is supplied in a 1 mL single-dose pre-filled autoinjector with a 27-gauge needle with a needle guard.

Each 1 mL contains 150 mg of atacicept-vymj, 0.82 mg sodium acetate, 79.98 mg trehalose, and Water for Injection. Sodium hydroxide and acetic acid are included to adjust the pH to 5.0.
