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.

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.

Biologic patent Exclusivity
🏛️Reference-product exclusivity
A flat 12 years of FDA market protection from first licensure. No biosimilar can be licensed before it ends — regardless of patents.
🧪Listed biologic patents
Patents the reference maker lists covering the molecule, formulation, or manufacturing. A biosimilar generally can’t launch until these resolve.
🔁Interchangeability
An interchangeable biosimilar may be substituted at the pharmacy (state laws vary). The first one can earn its own exclusivity period.
🛈 What do these terms mean?
Biologic patent
A patent the reference product’s maker has publicly listed. A biosimilar generally can’t launch until these expire — unless they’re invalidated or resolved in a settlement.
Reference-product exclusivity
A flat 12 years of FDA market protection from the biologic’s first licensure (the BPCIA). No biosimilar can be licensed before it ends, regardless of patents.
Interchangeable exclusivity
The first interchangeable biosimilar can earn a period as the only interchangeable version (pharmacists can substitute it without the prescriber).
Earliest biosimilar (LOE)
The latest of all the dates above — the soonest a biosimilar can realistically reach the market. Litigation and settlements can move it earlier.

Biologics have no small-molecule “generics” — competition comes from FDA-licensed biosimilars, tracked in the FDA Purple Book.

Common questions
Is there a biosimilar for ZYMFENTRA 120 MG/ML SYRINGE KT?
Yes — at least one FDA-licensed biosimilar is listed for this biologic. See the Purple Book family above for the available products.
Why do different websites show different biosimilar dates?
Biosimilar availability isn’t based on one single date. Some sources use the reference-product exclusivity, some use the last listed patent, and patent litigation, settlements, and licenses can all change the real-world launch date. This page shows the underlying Purple Book dates so you can see why estimates differ.
Can a biosimilar launch before the last patent expires?
Sometimes. A biosimilar maker may settle with the reference manufacturer or receive a license to launch earlier. In other cases, the last listed protection delays competition.
What does “current Purple Book estimate” mean?
It means we’re using the latest patent and exclusivity dates currently listed in the FDA Purple Book. It is not a guaranteed launch date.
What does “FDA listed” mean?
It means the product appears in the FDA’s official directory. That’s a good sign a product exists for the U.S. market, but on its own it does not confirm a pharmacy can get it today. Where we have recent retail pricing data, we label it “Availability likely” instead.
What does a patent or protection date mean here?
It’s the latest date currently listed in the FDA Purple Book for a patent or exclusivity on the reference biologic. It can affect when a biosimilar becomes widely available — but it is not a guaranteed launch date. Settlements and licenses can move the real date earlier or later.
Built from the FDA Purple Book Patent List (patents the reference-product sponsor has publicly listed under the BPCIA) plus reference-product exclusivity. Biosimilars cannot launch until these clear; patent litigation and settlements can shift the real date. Biologics have no small-molecule generics — competition comes from FDA-licensed biosimilars, not the Orange Book.
Where does this data come from?
Patents and exclusivity from the FDA Purple Book (biologics), refreshed from public FDA data. Biosimilar launch timing is an estimate, not a guarantee.

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.

The FDA label contains product information, but this exact NDC could not be matched safely to one product block. We intentionally withheld sibling strengths’ 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.

🚨 Boxed Warning ~2 min read ▾

WARNING: SERIOUS INFECTIONS and MALIGNANCY See full prescribing information for complete boxed warning Increased risk of serious infections leading to hospitalization or death, including tuberculosis (TB), bacterial sepsis, invasive fungal infections (such as hitoplasmosis) and infections due to ohter opportunistic pathogens. (5.1) Discontinue ZYMFENTRA if a patient develops a serious infection or sepsis. (5.1) Perform test for latent TB; if positive, start treatment for TB prior to starting ZYMFENTRA.

Monitor all patients for active TB during treatment, even if initial latent TB test is negative. (5.1) Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with tumor necrosis factor (TNF) blockers, including infliximab products. (5.2) Postmarketing cases of fatal hepatosplenic T-cell lymphoma (HSTCL) have been reported in patients treated with TNF blockers including infliximab products.

Almost all had received azathioprine or 6-mercaptopurine concomitantly with a TNF blocker at or prior to diagnosis. The majority of cases were reported in patients with Crohn's disease or ulcerative colitis, most of whom were adolescent or young adult males. (5.2 ) SERIOUS INFECTIONS Patients treated with TNF blockers, inculding ZYMFENTRA, are at increased risk for developing serious infections that may lead to hospitalization or death [ see Warnings and Precautions ( 5.1 ), Adverse Reactions ( 6.1 ) ].

Most patients who developed these infections were taking concomitant immunosuppressants such as methotrexate or corticosteroids. Discontinue ZYMFENTRA if a patient develops a serious infection or sepsis. Reported infections include: Active tuberculosis, including reactivation of latent tuberculosis.

Patients with tuberculosis have frequently presented with disseminated or extrapulmonary disease. Test patientsfor latent tuberculosis before ZYMFENTRA use and during therapy. Initiate treatment for latent infection prior to ZYMFENTRA use.

Invasive fungal infections, including histoplasmosis, coccidioidomycosis, candidiasis, aspergillosis, blastomycosis, and pneumocystosis. Patients with histoplasmosis or other invasive fungal infections may present with disseminated, rather than localized, disease. Antigen and antibody testing for histoplasmosis may be negative in some patients with active infection.

Consider empiric anti-fungal therapy in patients at risk for invasive fungal infections who develop severe systemic illness. Bacterial, viral and other infections due to opportunistic pathogens, including Legionella and Listeria. Carefully consider the risks and benefits of treatment with ZYMFENTRA prior to initiating therapy in patients with chronic or recurrent infection.

Closely monitor patients for the development of signs and symtoms of infection during and after treatment with ZYMFENTRA, including the possible development of tuberculosis in patients who tested negative for latent tuberculosis infection prior to initiating therapy. MALIGNANCY Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with TNF blockers, including infliximab products [ see Warnings and Precautions ( 5.2 ) ]. Postmarketing cases of hepatosplenic T-cell lymphoma (HSTCL), a rare type of T-cell lymphoma, have been reported in patients treated with TNF blockers, including infliximab products.

These cases have had a very aggressive disease course and have been fatal. Almost all patients had received treatment with azathioprine or 6-mercaptopurine concomitantly with a TNF blocker at or prior to diagnosis. The majority of reported cases have occurred in patients with Crohn’s disease or ulcerative colitis and most were in young adult males. [ see Use in Specific Population ( 8.4 ) ].

⚠️ Warnings and Cautions ~3 min read ▾

5 WARNINGS AND PRECAUTIONS Serious injections, including invasive fungal infections: Avoid use of ZYMFENTRA in patients with an active infection. If infection develops during treatment, conduct a prompt and complete diagnostic workup appropriate for an immunocompromised patient and initiate antimicrobial therapy. If systemic illness develops in patients who reside or travel to regions where mycoses are endemic, consider empiric antifungal therapy.

( 5.1 ) Malignancies : The incidence of malignancies, including lymphoma, was greater in TNF blocker-treated patients than in controls. Consider the higher risk of hepatosplenic T-cell lymphoma (HSTCL) with combination therapy versus increased tisk of immunogenicity and hypersensitivity reactions with monotherapy. ( 5.2 ) Hepatitis B virus (HBV) reactivation: Test for HBV infection before starting ZYMFENTRA.

Monitor HBV carriers during and several months after therapy for active HBV infection. If reactivation occurs, stop ZYMFENTRA and begin anti-viral therapy. ( 5.3 ) Hepatotoxicity: Severe hepatic reactions, some fatal or necessitating liver transplantation with infliximab products.

Monitor hepatic enzymes and liver function tests every 3 to 4 months during treatment; investigate liver enzyme elevations and interrupt treatment if drug-induced liver injury is suspected. Instruct patients to seek immediate medical attention if symptoms develop. ( 5.4 ) Congestive heart failure (CHF) : New onset or worsening symptoms may occur.

Avoid ZYMFENTRA in patients with CHF. Monitor for new or worsening symptoms if a decision is made to administer ZYMFENTRA. ( 5.5 ) Hematologic Reactions : Advise patients to seek immediate medical attention if signs and symtoms of cytopenia develop; consider stopping ZYMFENTRA if significant hematologic abnormalities devlop.

( 5.6 ) Hypersensitivity and Other Administration Reactions : Serious systemic hypersensitivity reactions including anaphylaxis; institute appropriate therapy and discontinue ZYMFENTRA. ( 4 , 5.7 ) Neurologic Reactions : Exacerbation or new onset CNS demyelinating disorders may occurs; consider discontinuation of ZYMFENTRA. ( 5.8 ) Risk of infection with concurrent administration of other biological products : Concurrent use with other immunosuppressive biological products may increase the risk of injection ( 5.9 ) Risk of additive immunosuppressive effects from prior biologic products : Consider the half-life and mode of action of prior biological products.

( 5.10 ) Autoimmunity : Formation of autoantibodies and development of lupus-like syndrome may occur; discontinue ZYMFENTRA if symptoms develop. ( 5.11 ) V accinations and Use of Live Vaccines/Therapeutic Infectious Agents: Prior to initiating ZYMFENTRA bring patients up to date with all vaccinations. Live vaccines or therapeutic infectious agents should not be given with ZYMFENTRA.

A 6-month waiting period following birth is recommended before the administration of live vaccines to infants exposed in utero to infliximab products. ( 5.12 )

5.1Serious Infections Patients treated with ZYMFENTRA are at increased risk for developing serious infections involving various organ systems and sites that may lead to hospitalization or death. Opportunistic infections due to bacterial, mycobacterial, invasive fungal, viral, or parasitic organisms including aspergillosis, blastomycosis, candidiasis, coccidioidomycosis, cryptococcosis, histoplasmosis, legionellosis, listeriosis, pneumocystosis, salmonellosis and tuberculosis have been reported with TNF blockers. Patients have frequently presented with disseminated rather than localized disease.

Treatment with ZYMFENTRA should not be initiated in patients with an active infection, including clinically important localized infections.Patients greater than 65 years of age, patients with comorbid-conditions and/or patients taking concomitant immunosuppressants such as corticosteroids or methotrexate may be at greater risk of infection.

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 data described below reflect exposure to ZYMFENTRA in 518 adult subjects in two 54-weekrandomized, double-blind, placebo-controlled trials in subjects with moderately to severely active ulcerative colitis (UC) or Crohn’s disease (CD) (UC Trial I an CD Trial I).

Subject who achieved clinical response following three induction doses of infliximab-dyyb administered as an intravenous infusion at Week 0, 2 and 6 were randomized 2:1 to ZYMFENTRA 120 mg or placebo as a subcutaneous injection every two weeks at Week 10 [ see Clinical Studies ( 14.1 and 14.2 )].

7 DRUG INTERACTIONS

7.1Other Biological Products Used to Treat UC and CD The concurrent use of ZYMFENTRA with other immunosuppressive biological products used to treat UC and CD may increase the risk of infection and is not recommended [ see Warnings and Precautions ( 5.9 ) ]. Consier the half-life and mode of action of prior biologial products to avoid unintended additive immunosuppressive effects when initiating ZYMFENTRA [ see Warnings and Precautions ( 5.10 ) ].

7.2Cytochrome P450 Substrates The formation of CYP450 enzymes may be suppressed by increased levels of cytokines (e.g., TNFα, IL-1, IL-6, IL-10, IFN) during chronic inflammation. Therefore, ZYMFENTRA, an antagonist of TNFα, could normalize the formation of CYP450 enzymes potentially resulting in a decrease in exposure of CYP450 substrates. Upon initiation or discontinuation of TNF blockers, including ZYMFENTRA, in patients being treated with CYP450 substrates requiring therapeutic drug monitoring, monitor therpeutic parameters (e.g., INR for warfarin) or drug concentration (e.g., cyclosporine or theophylline).

Dosage adjustment may be needed to maintain drug concentrations or parameters within the therapeutic range. See prescribing information for specific drugs.

7.3Live Vaccines/Therapeutic Infectious Agents It is recommended that live vaccines not be given concurrently with ZYMFENTRA. It is also recommended that live vaccines not be given to infants after in utero exposure to infliximab products for 6 months following birth [ see Warnings and Precautions ( 5.12 ) ]. It is recommended that therapeutic infectious agents not be given concurrently with ZYMFENTRA [ see Warnings and Precautions ( 5.12 ) ].

8 USE IN SPECIFIC POPULATIONS

8.1Pregnancy Risk Summary Available data from reports of pregnancy in clinical trials with ZYMFENTRA are insufficient to identify a drug associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. There are risks to the mother and the fetus associated with inflammatory bowel disease in pregnancy ( see Clinical Considerations ). Available observational data in pregnant women exposed to infliximab products administered intravenously showed no increased risk of major malformations among live births as compared to those exposed to non-biologics.

Most TNF blockers, such as infliximab products, administered intravenously are transferred across the placenta during the third trimester of pregnancy and may affect immune response in the in utero exposed infant. Infants exposed in utero should not be administered live vaccines for at least 6 months after birth ( see Clinical Considerations ). Because infliximab products do not cross-react with TNFα in species other than humans and chimpanzees, animal reproduction studies have not been conducted with ZYMFENTRA.

The background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.

Clinical Consideration Disease-Associated Maternal and/or Embryo/Fetal Risk Published data suggest that there is an increased risk of adverse pregnancy outcomes in women with inflammatory bowel disease associated with increased disease activity. Adverse pregnancy outcomes include preterm delivery (before 37 weeks of gestation), low birth weight (less than 2.5 kg) and small for gestational age at birth. Fetal/Neonatal Adverse Reactions The risk of fetal/neonatal adverse reactions with in utero exposure to infliximab-dyyb administered subcutaneously is unknown.

However, most TNF blockers, such as infliximab products, cross the placenta and have been detected in infant serum up to 6 months following birth. Consequently, infants exposed to infliximab products may be at increased risk of infection, including disseminated infection which can become fatal. At least a six-month waiting period following birth is recommended before the administration of live vaccines (e.g., BCG vaccine or other live vaccines, such as the rotavirus vaccine) to infants exposed to intravenous infliximab in utero [ see Warnings and Precautions (5.12) ].

Cases of agranulocytosis in infants exposed to intravenous infliximab in utero have also been reported. Therefore, ZYMFENTRA, administered during pregnancy may affect immune responses in the in utero-exposed newborn and infant [ see Adverse Reactions 6.2 ]. Data Animal Data Because infliximab products do not cross-react with TNFα in species other than humans and chimpanzees, animal reproduction studies have not been conducted with ZYMFENTRA.

8.2Lactation Risk Summary There are no data on the presence of infliximab-dyyb or its metabolites in either human or animal milk, the effects on the breastfed infant, or the effects on milk production after subcutaneous administration. Published literature show that infliximab is present at low levels in human milk after intravenous administration. Systemic exposure in a breastfed infant is expected to be low because infliximab products are largely degraded in the gastrointestinal tract.

The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for ZYMFNETRA and any potential adverse effects on the brestfed child from ZYMFENTRA or from the underlying maternal condition.

8.4Pediatric Use The safety and effectiveness in pediatric patients have not been established.

12 CLINICAL PHAMACOLOGY

12.1Mechanism of Action Infliximab-dyyb neutralize the biological activity of TNFα by binding with high affinity to the soluble and transmembrane forms of TNFα and inhibit binding of TNFα with its receptors. Infliximab-dyyb has shown biological activities, such as TNFα neutralization activity and TNFα binding affinities, complement 1q (C1q) binding affinity and crystallizable fragment (Fc) receptor binding affinities in a wide variety of in vitro bioasays. The relationship of these biological response markers to the mechanism(s) by which infliximab-dyyb exerts its clinical effects is unknown.

12.2Pharmacodynamics No formal pharmacodynamic studies have been conducted.

12.3Phamacokinetics Following single and multiple subcutaneous dosing of infliximab-dyyb, exposures to infliximab-dyyb (i.e., AUC) are proportionally increased over the dose range from 120 mg to 240 mg (2 times the recommended dosage). After a single subcutaneous dose of infliximab-dyyb 120 mg in healthy subjects, the median (SD) C max and AUC inf were 10.0 (3.2) mcg/mL and 6945.6 (2830.2) mcg·h/mL, respectively. Following recommended subcutaneous maintenance dose of ZYMFENTRA (120 mg every 2 weeks) in adult subjects with UC and CD from Week 10 after intravenous induction treatment with infliximab-dyyb, steady-state was achieved by Week 22, and the mean (SD) trough serum concentrations of infliximab-dyyb at steady-state were 14.6 (7.8) mcg/mL and 14.6 (8.9) mcg/mL in subjects with UC and CD, respectively.

Pharmacokinetics are comparable between healthy subjects, and subjects with UC or CD. Absorption In healthy subjects, the median time to reach the maximum serum concentration (T max ) was 7 days after a single subcutaneous dose of infliximab-dyyb 120 mg. In healthy subjects, AUC inf following a single subcutaneous dosed of infliximab-dyyb 120 mg was approximately 23% relative to a single intravenous dose of infliximab-dyyb 5 mg/kg.

Following infliximab-dyyb 120 mg subcuaneosly every 2 weeks, steady state AUC for 8-week internal was 25-35% higher compared to infliximab-dyyb 5 mg/kg administered intravenously every 8 weeks in subjects with UC and CD. Distribution Population pharmacokinetic analyses showed that the volume of distribution of infliximab-dyyb was 3.36L. Elimination In healthy subjects, the mean half-life was 332 hours after a single subcutaneous dose of infliximab-dyyb 120 mg.

Populatoin pharmacokinetic analyses showed that the clearance of infliximab-dyyb was 0.013 L/hr and the clearance was increased in the presence of anti-drug antibody. The metabolic pathway of infliximab has not been characterized. As a IgG1κ monoclonal antibody, infliximab is expected to be degraded into small peptides and amino acids via catabolic pathways in the same manner as endogenous IgG.

Specific Populations Weight Population pharmacokinetic analysis indicated that exposure to infliximab-dyyb was inversely related to body weight. However, the magnitude of body weight effect on systemic exposure was not clinically meaningful in adult subjects with UC and CD weighing from 39 to 130 kg. Age, Sex and Race Age (≥65 years ofld), sex, or race did not have a clinically meaningful effect on pharmacokinetics of infliximab-dyyb.

Drug Interaction Studies Population pharmacokinetic analysis showed that co-administered methotrexate did not have clinically meaningful effect on the pharmacokinetics of infliximab-dyyb.

12.6Immunogenicity The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Difference in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies in the studies described below with the incidence of anti-drug antibodies in other studies, including those of infliximab-dyyb or of other infliximab products. In UC and CD clinical studies (UC Trial I and CD Trial I), approximately 64% subjects developed anti-drug antibodies to infliximab-dyyb following induction t… [Excerpted — this section continues on DailyMed.]

This Medication Guide has been approved by the U.S. Food and Drug Administration Revised: 02/2024 MEDICATION GUIDE ZYMFENTRA TM (Zim fen' trah) (infliximab-dyyb) injection, for subcutaneous use Read the Medication Guide that comes with ZYMFENTRA before you receive the first treatment, and before each time you receive a treatment of ZYMFENTRA. This Medication Guide does not take the place of talking with your doctor about your medical condition or treatment.

What is the most important information I should know about ZYMFENTRA ? ZYMFENTRA may cause serious side effects, including: 1. Risk of infection ZYMFENTRA is a medicine that affects your immune system.

ZYMFENTRA can lower the ability of your immune system to fight infections. Serious infections have happened in patients receiving ZYMFENTRA. These infections include tuberculosis (TB) and infections caused by viruses, fungi, or bacteria that have spread throughout the body.

Some patients have died from these infections. Your doctor should test you for TB before starting ZYMFENTRA. Your doctor should monitor you closely for signs and symptoms of TB during treatment with ZYMFENTRA.

Before starting ZYMFENTRA, tell your doctor if you: think you have an infection. You should not start receiving ZYMFENTRA if you have any kind of infection. are being treated for an infection. have signs of an infection, such as a fever, cough, flu-like symptoms. have any open cuts or sores on your body. get a lot of infections or have infections that keep coming back. have diabetes or an immune system problem as people with these conditions have a higher chance for getting infections. have TB, or have been in close contact with someone with TB. live or have lived in certain parts of the country (such as the Ohio and Mississippi River valleys) where there is an increased risk for getting certain kinds of fungal infections (histoplasmosis, coccidioidomycosis, or blastomycosis); these infections may develop or become more severe if you receive ZYMFENTRA.

If you do not know if you have lived in an area where histoplasmosis, coccidioidomycosis, or blastomycosis is common, ask your doctor. have or have had hepatitis B. use the medicines KINERET (anakinra), ORENCIA (abatacept), or other medicines called biologics used to treat the same conditions as ZYMFENTRA. After starting ZYMFENTRA, if you have an infection, any sign of an infection including a fever, cough, flu-like symptoms, or have open cuts or sores on your body, call your doctor right away. ZYMFENTRA can make you more likely to get infections or make any infection that you have worse.

2. Risk of Cancer There have been cases of unusual cancers in children and teenage patients using tumor necrosis factor (TNF) blocker medicines, such as ZYMFENTRA. For people receiving TNF blocker medicines, including ZYMFENTRA, the chances of getting lymphoma or other cancers may increase.

Some people receiving TNF blockers, including ZYMFENTRA, developed a rare type of cancer called hepatosplenic T-cell lymphoma. This type of cancer often results in death. Most of these people were male teenagers or young men.

Also, most people were being treated for Crohn's disease or ulcerative colitis with a TNF blocker and another medicine called azathioprine or 6-mercaptopurine. People who have been treated for Crohn's disease and ulcerative colitis, for a long time may be more likely to develop lymphoma. This is especially true for people with very active disease.

Some people treated with infliximab products, such as ZYMFENTRA, have developed certain kinds of skin cancer. If any changes in the appearance of your skin or growths on your skin occur during or after your treatment with ZYMFENTRA, tell your doctor. Patients with Chronic Obstructive Pulmonary Disease (COPD), a specific type of lung disease, may have an increased risk for getting cancer while being treated with ZYMFENTRA.

Tell your doctor if you have ever had any type of cancer. Discuss with your doctor any need to a… [Excerpted — this section continues on DailyMed.]

14 CLINICAL STUDIES

14.1Adult Ulcerative Colitis The safety and efficacy of ZYMFENTRA were assessed in a randomized, double-blind, placebo-controlled clinical trial (UC Trial I; NCT04205643 ) in adult subjects with moderately to severely active UC (defined as a modified Mayo score [mMS] between 5 to 9 with an endoscopic subscore [ES] of 2 or 3). The mMS is a 3-component Mayo score (0-9), which consists of following subscores (0 to 3 for each subscore): stool frequency (SFS), rectal bleeding (RBS), and findings on centrally read endoscopy score (ES).

An ES of 2 was defined by marked erythema, lack of vascular pattern, any friability, and/or erosions, and a score of 3 was defined by spontaneous bleeding and ulceration. Subjects had demonstrated an inadequate response or intolerance to treatment with corticosteroids alone or in combination with 6-mercaptopurine or azathioprine. Subjects were permitted to use stable doses of oral aminosalicylates, oral corticosteroids (prednisone ≤20 mg/day or equivalent, budesonide ≤9 mg/day), UC-related antibiotics, and/or immunomodulatory agents (azathioprine, 6-mercaptopurine, or methotrexate).

Corticosteroid tapering was permitted after Week 10. All subjects received three intravenous induction doses of 5 mg/kg of infliximab-dyyb at Weeks 0, 2 and 6. In order to be randomized to treatment in UC Trial I, subjects had to be in clinical response at Week 10.

Clinical response was defined as a decrease from baseline in the mMS of at least 2 points and at least 30%, with an accompanying decrease in the RBS of at least 1 point or an aabsolute RBS of 0 or 1 point. A total of 438 subjects were randomized at Week 10 in a double-blind fashion (2:1) to ZYMFENTRA 120 mg as a subcutaneous injection or placebo every two weeks. At the time of randomization into the double-blind phase (Week 10), 92% were receiving aminosalicylates, 41% were receiving oral corticosteroids, and 22% were receiving immunomodulators including AZA, 6-MP or MTX.

A total of 10% of randomized subjects had prior exposure to biological poucts or JAK inhibitors. Subjects in the boule-blind phase had a mean age of 39 years (range 18 to 75 years); 44% were female; and 98% identified as White, and 2% as American Indian or Alaska Native. The primary endpoint was the proportion of subjects in clinical remission at Week 54.

Wecondary endpoints included the proportion of subjects achieving histologic-endoscopic mucosal improvement and corticosteroid-fee remission at Week 54 (see Table 3 ).

Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Zymfentra — the program that covers self-administered drugs. 1 manufacturer.
⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Zymfentra. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

💵 About the dollar figures: spending is what Part D plans paid before confidential manufacturer rebates, so the program’s real net cost is lower. A blank patient count means fewer than 11 people — CMS hides counts that small to protect privacy. Source: CMS Medicare Quarterly Part D Spending by Drug (data.cms.gov), updated quarterly.

About this NDC listing & data coverage

Finished prescription product Kit / multi-component package

Kit / multi-component package

This NDC identifies a kit — a package containing more than one component. Structured data (pricing, ingredients, equivalents) is often reported per component rather than for the kit NDC itself, which can make this page look thinner than the components' own pages.

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 form printed on the packaging and shown on DailyMed is the one the FDA registered. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero and the dashes are dropped. The Identity section at the top of this page lists each form of this code.
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 CELLTRION USA Inc.. Listing status can change — the directory data on this page refreshes weekly.
Does this product come in other package sizes?
Yes — the FDA directory lists 11 other package presentations of this same product, including 1 kit (72606-0025-01), 1 kit (72606-0025-05), 1 kit (72606-0025-09). Each has its own NDC and its own page — see the package list near the top of this page.
Who lists this product with the FDA?
CELLTRION USA 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.
Where does this data come from?
Listing facts (marketing category, packager status, marketing dates) from the FDA openFDA NDC Directory; label availability from DailyMed; pricing coverage from CMS NADAC; equivalence scope from the FDA Orange Book.
For educational and professional reference only — not medical advice. Pricing reflects published NADAC and CMS ASP (free public data) and may differ from your acquisition cost; always verify before billing or dispensing.
