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:
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)].
ZYMFENTRA is indicated in adults for maintenance treatment of:
▫ All patients mush coplete an intravenous induction regimen with an infliximab product before starting ZYMFENTRA. For induction dosing information, see the corresponding full prescribing information for the chosen infliximab product.
ZYMFENTRA is contraindicated in patients with a history of a severe hypersensitivity reaction to infliximab-dyyb, other infliximab products, any of the inactive ingredients in ZYMFENTRA, or any murine proteins. Reactions have included anaphylaxis [see Warnings and Precautions (5.7)].
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. The risks and benefits of treatment should be considered prior to initiating therapy in patients:
Tuberculosis
Cases of reactivation of tuberculosis or new tuberculosis infections have been observed in patients receiving TNF-blockers, including patients who have previously received treatment for latent or active tuberculosis. Cases of active tuberculosis have also occurred in patients being treated with infliximab products during treatment for latent tuberculosis. Evaluate patients for tuberculosis risk factors and test for latent infection prior to initiating ZYMFENTRA and periodically during therapy.
Treatment of latent tuberculosis infection prior to therapy with TNF blockers has been shown to reduce the risk of tuberculosis reactivation during therapy. Induration of 5 mm or greater with tuberculin skin testing should be considered a positive test result when assessing if treatment for latent tuberculosis is needed prior to initiating ZYMFENTRA even for patients previously vaccinated with Bacille Calmette-Guérin (BCG).
Consider anti-tuberculosis therapy prior to initiation of ZYMFENTRA in patients with a past history of latent or active tuberculosis in whom an adequate course of treatment cannot be confirmed, and for patients with a negative test for latent tuberculosis but having risk factors for tuberculosis infection. Consultation with a physician with expertise in the treatment of tuberculosis is recommended to aid in the decision whether initiating anti-tuberculosis therapy is appropriate for an individual patient.
Tuberculosis should be strongly considered in patients who develop a new infection during treatment with ZYMFENTRA especially in patients who have previously or recently traveled to countries with a high prevalence of tuberculosis, or who have had close contact with a person with active tuberculosis.
Monitoring
Closely monitor patients for the development of signs and symptoms of infection during and after treatment with ZYMFENTRA including the development of tuberculosis in patients who tested negative for latent tuberculosis infection prior to initiating therapy. Tests for latent tuberculosis infection may also be falsely negative while on therapy with ZYMFENTRA.
Discontinue ZYMFENTRA if a patient develops a serious infection or sepsis. A patient who develops a new infection during treatment with ZYMFENTRA should undergo prompt and complete diagnostic workup appropriate for an immunocompromised patient; and appropriate antimicrobial therapy should be initiated, and the patient should be closely monitored.
Invasive Fungal Infections
For patients who reside or travel in regions where mycoses are endemic, invasive fungal infection should be suspected if they develop a serious systemic illness. Appropriate empiric antifungal therapy should be considered while a diagnostic workup is being performed. Antigen and antibody testing for histoplasmosis may be negative in some patients with active infection. When feasible, the decision to administer empiric antifungal therapy in these patients should be made in consultation with a physician with expertise in the diagnosis and treatment of invasive fungal infections and should take into account both the risk for severe fungal infection and the risks of antifungal therapy.
Malignancies, some fatal, have been reported among children, adolescents and young adults who received treatment with TNF blockers (initiation of therapy ≤18 years of age), including infliximab products. Approximately half of these cases were lymphomas, including Hodgkin’s and non-Hodgkin’s lymphoma. The other cases represented a variety of malignancies, including rare malignancies that are usually associated with immunosuppression and malignancies that are not usually observed in children and adolescents. The malignancies occurred after a median of 30 months (range 1 to 84 months) after the first dose of TNF blocker therapy. Most of the patients were receiving concomitant immunosuppressants. These cases were reported postmarketing and are derived from a variety of sources, including registries and spontaneous postmarketing reports.
Lymphomas
In the controlled portions of clinical trials of TNF blockers, more cases of lymphoma have been observed among patients receiving a TNF blocker compared with control patients. Cases of acute and chronic leukemia have been reported with postmarketing TNF blocker use, including infliximab products.
Hepatosplenic T-cell Lymphoma (HSTCL)
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 the immunosuppressants 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 adolescent and young adult males. It is uncertain whether the occurrence of HSTCL is related to TNF blockers or TNF blockers in combination with these other immunosuppressants. When treating patients, consideration of whether to use ZYMFENTRA alone or in combination with other immunosuppressants such as azathioprine or 6-mercaptopurine should take into account a possibility that there is a higher risk of HSTCL with combination therapy versus an observed increased risk of immunogenicity and hypersensitivity reactions with TNF blocker monotherapy from the clinical trial data [see Warnings and Precautions (5.7)]
Skin Cancer
Melanoma and Merkel cell carcinoma have been reported in patients treated with TNF blocker therapy, including infliximab products. Periodic skin examination is recommended for all patients during treatment with ZYMFENTRA, particularly those with risk factors for skin cancer.
Cervical Cancer
Cases of invasive cervical cancer have been reported postmarketing in women who received infliximab products for other conditions. A causal relationship between infliximab products and cervical cancer cannot be excluded. Routine cervical cancer screening is recommended during treatment with ZYMFENTRA.
Other Malignancies
In the controlled portions of clinical trials of some TNF blockers, including infliximab products, more malignancies (excluding lymphoma and nonmelanoma skin cancer) have been observed in patients receiving those TNF blockers compared with control patients. The most common malignancies were breast, colorectal, and melanoma in these controlled trials of TNF blockers.
In controlled trials of TNF blockers in adult patients at higher risk for malignancies (i.e., patients with COPD with a significant smoking history and cyclophosphamide-treated patients with Wegener’s granulomatosis), a greater proportion of malignancies occurred in the TNF blocker group compared to the control group. Patients had a history of heavy smoking. Avoid ZYMFENTRA in patients with moderate to severe COPD.
The potential role of TNF blockers in the development of malignancies is not known. Avoid ZYMFENTRA treatment in patients with a history of malignancy or in continuing treatment in patients who develop malignancy while receiving ZYMFENTRA.
Use of TNF blockers has been associated with reactivation of hepatitis B virus (HBV) in patients who are chronic carriers of this virus. In some instances, HBV reactivation occurring in conjunction with TNF blocker therapy has been fatal. The majority of these reports have occurred in patients concomitantly receiving other medications that suppress the immune system, which may also contribute to HBV reactivation.
Test patients for HBV infection before initiating TNF blocker therapy, including ZYMFENTRA. For patients who test positive for hepatitis B surface antigen, consultation with a physician with expertise in the treatment of hepatitis B is recommended. Adequate data are not available on the safety or efficacy of treating patients who are carriers of HBV with antiviral therapy in conjunction with TNF blocker therapy to prevent HBV reactivation. Patients who are carriers of HBV and require treatment with TNF blockers, including ZYMFENTRA, should be closely monitored for clinical and laboratory signs of active HBV infection throughout therapy and for several months following termination of therapy.
In patients who develop HBV reactivation, discontinue ZYMFENTRA and initiate antiviral therapy with appropriate supportive treatment. The safety of resuming TNF blocker therapy after HBV reactivation is controlled is not known. Therefore, prescribers should exercise caution when considering resumption of ZYMFENTRA in this situation and monitor patients closely.
Hepatobiliary disorders, including acute liver failure, jaundice abnormal hepatic function, hepatic steatosis, hepatitis, hepatotoxicity, hyperbilirubinemia and non-alcoholic fatty liver, have been reported in postmarketing data in patients receiving infliximab products. Autoimmune hepatitis has been diagnosed in some of these cases. Severe hepatic reactions occurred between two weeks to more than one year after initiation of infliximab products administered intravenously; elevations in hepatic aminotransferase levels were not noted prior to discovery of the liver injury in many of these cases. Some of these cases were fatal or necessitated liver transplantation.
In clinical trials, three subjects treated with ZYMFENTRA had drug induced liver injury based on hepatic transaminase elevations, including one subject with accompanying bilirubin elevation [see Adverse Reactions (6.2)].
Monitor hepatic enzymes and liver function tests every 3 to 4 months during treatment with ZYMFENTRA. Prompt investigation of the cause of liver enzyme elevation should be undertaken to identify potential cases of drug-induced liver injury. Interrupt treatment if drug-induced liver injury is suspected, until this diagnosis is excluded. Instruct patients to seek immediate medical attention if they experience symptoms suggestive of hepatic dysfuction.
Cases of worsening congestive heart failure (CHF) and new onset CHF, with and without identifiable precipitating factors (e.g., pre-existing cardiovascular disease), have been reported with TNF blockers, including infliximab products. Some of these patients have been under 50 years of age, and some cases had a fatal outcome. In several exploratory trials of other TNF blockers in the treatment of CHF, there were greater proportions of TNF-blocker-treated patients who had CHF exacerbations requiring hospitalization or increased mortality. ZYMFENTRA has not been studied in patients with a history of CHF. Avoid ZYMFENTRA in patients with CHF.
If a decision is made to administer ZYMFENTRA to patients with CHF, closely monitor patients during therapy for new or worsening symptoms of heart failure and discontinue ZYMFENTRA if symptoms appear.
Report of pancytopenia including aplastic anemia have been reported with TNF blocking agents. Cases of leukopenia, neutropenia, thrombocytopenia, and pancytopenia, some with a fatal outcome, have been reported in patients receiving infliximab products. Clinically significant events of neutropenia were noted in the clinical trials of ZYMFENTRA. The causal relationship to infliximab product therapy remains unclear. Although no high-risk group(s) has been identified, avoid ZYMFENTRA in patients who have ongoing or a history of significant hematologic abnormalities. Advise all patients to seek immediate medical attention if they develop signs and symptoms suggestive of blood dyscrasias or infection (e.g., persistent fever) during treatment with ZYMFENTRA. Consider discontinuation of ZYMFENTRA therapy in patients who develop significant hematologic abnormalities.
In clinical trials of ZYMFENTRA, symptoms compatible with hypersensitivity reactions have been reported including bronchospasm, dyspnea, rash, and edema. In post-marketing experience, serious systemic hypersensitivity reactions (including anaphylaxis, hypotension, and serum sickness) have been reported following administration of infliximab products. If an anaphylactic or other clinically significant hypersensitivity reaction occurs, institute appropriate therapy and discontinue ZYMFENTRA. There are no data on the risks of using ZYMFENTRA in patients who have experienced a severe hypersensitivity reaction towards another TNF blocker; in these patients, caution is needed.
Agents that inhibit TNF have been associated with central nervous system (CNS) manifestation of systemic vasculitis, seizure and new onset or exacerbation of clinical symptoms and/or radiographic evidence of CNS demyelinating disorders, including multiple sclerosis and optic neuritis, and peripheral demyelinating disorders, including Guillain-Barré syndrome. Avoid the use of ZYMFENTRA in patients with these neurologic disorders and consider discontinuation of ZYMFENTRA if these disorders develop.
Serious infections and neutropenia have been reported with concurrent use of TNF-blockers and other immunosuppressive biological products (e.g., anakinra and abatacept). The concurrent use of ZYMFENTRA with other immunosuppressive biological products used to treat ulcerative colitis and Crohn’s disease may increase the risk of infection and is not recommended [see Drug Interactions (7.1)].
Consider the half-life and mode of action of prior biological products to avoid unintended additive immunosuppressive effects when initiating ZYMFENTRA [see Drug Interactions (7.1)].
Treatment with TNF blockers, iincluding ZYMFENTRA may result in the formation of autoantibodies and in the development of a lupus-like syndrome. If a patient develops symptoms suggestive of a lupus-like syndrome following treatment with ZYMFENTRA, discontinue treatment.
Vaccinations
Prior to initiating ZYMFENTRA in adult patients, update vaccinations in accordance with current vaccination guidelines.
Live Vaccines and Theraeputic Infectious Agents
In patients receiving TNF blockers, limited data are available on the response to vaccination with live vaccines or on the secondary transmission of infection by live vaccines. Use of live vaccines can result in clinical infections, including disseminated infections. The concurrent administration of live vaccines with ZYMFENTRA is not recommended.
Fatal outcome due to disseminated BCG infection has been reported in an infant who received a BCG vaccine after in utero exposure to infliximab products. Infliximab is known to cross the placenta and has been detected in the serum of infants up to 6 months following birth. A 6-month waiting period following birth is recommended before the administration of any live vaccine to infants exposed in utero to infliximab products.
Other uses of therapeutic infectious agents such as live attenuated bacteria (e.g., BCG bladder instillation for the treatment of cancer) could result in clinical infections, including disseminated infections. It is recommended that therapeutic infectious agents not be given concurrently with ZYMFENTRA.

Infections
In UC Trial I, at leaset one serious infection was reported in 3% of ZYMFENTRA-treated subjects compared to 1% in the plaebo group. Serious infections in the ZYMFENTRA-treated subjects were COVID-19, cystitis, pneumonia, salpingitis, and urinary tract injection [seeWarnings and Precautions (5.1)].
In CD Trial I, infections were observed in 30% of ZYMFENTRA-treated subjects compare to 17% of placebo-treated subjects. At least one serious infection was reported in 3% of ZYMFENTRA-treated subjects compared to 1% in the placebo group. Serious infections in the ZYMFENTRA-treated subjects were abscess, appendicitis, bacterial arthritis, bartholinitis, bronchiolitis, and urinary tract infection [seeWarnings and Precautions (5.1)].
Malignancies
In UC Trial I, malignancy (prostate cancer) was reported in a ZYMFENTRA-treated subject. No malignancies were reported among placebo-treated subjects [seeWarnings and Precautions (5.2)].
In another clinical trial in patients with CD, one malignancy (non-small cell lung cancer) was reported in a ZYMFENTRA-treated subject [see Warnings and Precautions (5.2)].
Hepatotoxicity
Three cases of drug induced liver injury were noted in ZYMFENTRA-treated subjects that led to study drug discontinuation [see Warnings and Precautions (5.4)].
The following adverse reactions have been identified during post-approval use of outside of the U.S with a non-U.S approved infliximab product administered subcutaneously. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
The following additional adverse ractions have been identified during post-approval use of infliximab products administered intravenously.
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 [seeWarnings and Precautions (5.9)].
Consider the half-life and mode of action of prior biological products to avoid unintended additive immunosuppressive effects when initiating ZYMFENTRA [see Warnings and Precautions (5.10)].
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.
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)].
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].
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.
Infliximab-dyyb, a tumor necrosis factor (TNF) blocker, is a chimeric IgG1κ monoclonal antibody (composed of human constant and murine variable regions). It has a molecular weight of approximately 145.9 kDa. Infliximab-dyyb is produced by a recombinant murine myeloma cell line, SP2/0.
ZYMFENTRA (inifliximab-dyyb) injection for subcutaneous use is a sterile, preservative-free, clear to opalescent, colorless to pale brown solution.
ZYMFENTRA is supplied in a single-dose prefilled syringe with 29 gauge fixed 1/2 inch needle, prefilled syringe with 29 gauge fixed 1/2 inch needle with needle guard, or prefilled pen with 27 gauge fixed 1/2 inch needle.
Each mL of solution contains 120 mg infliximab-dyyb, acetic acid (0.19 mg), polysorbate 80 (0.5 mg), sodium acetate (0.56 mg), sorbitol (45 mg) and Water for Injection, USP. The pH is 5.0.
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.
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) Cmax and AUCinf 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 (Tmax) was 7 days after a single subcutaneous dose of infliximab-dyyb 120 mg. In healthy subjects, AUCinf 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 3.36 L.
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.
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 treatment with infliximab-dyyb intravenously and maintenance treatment with ZYMFENTRA by Week 54 [183/287 (64%) in subjects with UC, and 151/232 (65%) in subjects with CD] [see Clinical Studies (14)]. Among subjects with anti-drug antibodies, 92% had neutralizing antibodies [161/183 (88%) subjects with UC, and 147/151 (97%) subjects with CD]. Use of concomitant immunosuppressant agents (azathioprine, 6-mercaptopurine and methotrexate) appeared to reduce the frequency of ADA to infliximab-dyyb.
Subjects who were positive for anti-drug antibodies showed lower infliximab-dyyb trough seum concentrations of infliximab-dyyb by approximately 30 to 40% compared to subjects who were negative for anti-drug antibodies. In some subjects with high titers of anti-drug antibodies and positive neutralizing antibodies, trough seum concentrations of infliximab-dyyb were below the lower limit of quantitation (<0.1 mcg/mL). There was no identified clinically significant effect of anti-drug antibodies on the safety and effectiveness of ZYMFENTRA in Study UC I and Study CD I.
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 absolute 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. Secondary endpoints included the proportion of subjects achieving histologic-endoscopic mucosal improvement and corticosteroid-fee remission at Week 54 (see Table 3).

The relationship between histologic-endoscopic mucosal improvement at Week 54 and disease progression and longer-term outcomes after Week 54 was not evaluated in UC Trial I.
The safety and efficacy of ZYMFENTRA were assessed in a randomized, double-blind, placebo-controlled clinical studies (CD Trial I; NCT03945019) in adult subjects with moderately to severely active CD, defined as Crohn's Disease Activity Index (CDAI) score of 220 to 450 points, and a centrally-reveiwed Simplified Endoscopic Activity Score for Crohn’s Disease (SES-CD) of ≥6 points for ileal-colonic CD (or ≥4 points for isolated ileal disease).
Subjects had demonstrated an inadequate response or intolerance to treatment with corticosteroids and/or immunosuppressants. Subjects were permitted to use stable doses of oral amisosalicylates, oral corticosteroids (prednisone ≤20 mg/day or equivalent, budesonide ≤9 mg/day), CD-related antibiotics and/or immunomodulatory agents (azathioprine, 6-mercaptopurine, or methotrexate). Corticosteroid dose was tapered after Week 10.
All subjects received three intravenous induction doses of 5 mg/kg infliximab-dyyb at Week 0, 2 and 6. In order to be ranomized to treatment in CD Trial I, subjects had to be in clinical response at Week 10. Clinical response was defined as a decrease from baseline in CDAI of at least 100 points (i.e., CDAI-100 responders).
A total of 323 subjects were randomized at Week 10 in a double-blind fashion (2:1) to ZYMFENTRA 120 mg as a subcutaneous injection or placebo every 2 weeks.
At the time of randomization into the double-blind phase (Week 10), 61% were receiving aminosalicylates, 40 % were receiving oral corticosteroids, and 32% were receiving immunomodulators including azathioprine, 6-mercaptopurine, or methotrexate.
A total of 11% of randomized subjects had prior exposure to biological products.
Subjects in the double-blind phase had a mean age of 35 years (range 18 to 75 years); 40% were female; and 91% identified as White, 4% identified as American Indian or Alaska Native, 4% identified as Asian, 0.3% as Black or African American, and 1% identified as another racial group.
The co-primary endopoints were clinical remission (based on CDAI) and endoscopic response at Week 54. Secondary endpoints included endoscopic remission, and corticosteroid-free remission at Week 54 (see Table 4).
