Most hypersensitivity reactions, which include anaphylaxis, urticaria, dyspnea, and/or hypotension, have occurred during or within 2 hours of infusion. Herpes zoster was reported for 2 patients in the every 8-week maintenance treatment group. You should discuss any concerns about your health and medical care with your doctor. Eight percent also had rectovaginal fistulas. Upon initiation or discontinuation of Renflexis in patients being treated with CYP450 substrates with a narrow therapeutic index, monitoring of the effect (e.g., warfarin) or drug concentration (e.g., cyclosporine or theophylline) is recommended and the individual dose of the drug product may be adjusted as needed. The more common side effects of RENFLEXIS include risk of infection. Infliximab products prevent disease in transgenic mice that develop polyarthritis as a result of constitutive expression of human TNF, and when administered after disease onset, allow eroded joints to heal. Despite the increase in antibody formation, the infusion reaction rates in Studies I and II in patients treated with 5 mg/kg induction followed by every 8 week maintenance for 1 year and in Study III in patients treated with 5 mg/kg induction (14.1%-23.0%) and serious infusion reaction rates (<1%) were similar to those observed in other study populations. These infections include tuberculosis (TB) and infections caused by viruses, fungi or bacteria that have spread throughout the body. Patients who had a negative TB skin test before receiving infliximab products have developed active TB. The patients in the infliximab group demonstrated continued inhibition of structural damage at Week 54. ORGANON and the ORGANON Logo are trademarks of the Organon group of companies. All patients received 5 mg/kg infliximab at Weeks 0, 2 and 6. Of patients who did not have an infusion reaction during the induction period, 9% experienced an infusion reaction during the maintenance period. Premedication could include antihistamines (anti-H1 +/- anti-H2), acetaminophen and/or corticosteroids. What should I tell my doctor before I take RENFLEXIS? In general, patients who developed ALT and AST elevations were asymptomatic, and the abnormalities decreased or resolved with either continuation or discontinuation of infliximab, or modification of concomitant medications. Even if your TB test is negative, your doctor should carefully monitor you for TB infections while you are taking RENFLEXIS. 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 onset of serious infections may be preceded by constitutional symptoms such as fever, chills, weight loss, and fatigue. In the second trial (ACCENT II [Study Crohn's II]), patients who were enrolled had to have at least 1 draining enterocutaneous (perianal, abdominal) fistula. have TB, or have been in close contact with someone with TB. Infliximab products cross the placenta, and have been detected in the serum of infants up to 6 months following birth. headache. Your congestive heart failure may get worse while you are receiving Renflexis. 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. (Median follow-up was 53 weeks.). Similar responses were seen in patients with each of the subtypes of psoriatic arthritis, although few patients were enrolled with the arthritis mutilans and spondylitis with peripheral arthritis subtypes. No worsening in the SF-36 mental component summary score was observed. A higher incidence of antibodies to infliximab was observed in Crohn's disease patients receiving infliximab after drug-free intervals >16 weeks. While the proportion of patients with infections was also higher in the younger age group (60% vs. 49%), for serious infections, the proportions were similar in the two age groups (13% in the 6 to 11 year age group vs. 11% in the 12 to 17 year age group). Some patients, especially those 65 years and older, have had serious infections caused by viruses, fungi, or bacteria that have spread throughout the body, including tuberculosis (TB) and histoplasmosis. The sPGA is a 6-category scale ranging from "5 = severe" to "0 = cleared" indicating the physician's overall assessment of the psoriasis severity focusing on induration, erythema, and scaling. In the first trial, 94 patients received 3 doses of either placebo or infliximab at Weeks 0, 2 and 6. Antigen and antibody testing for histoplasmosis may be negative in some patients with active infection. Care should be taken when switching from one biologic to another, since overlapping biological activity may further increase the risk of infection. Skin Cancerany changes in or growths on your skin. How many biosimilars have been approved in the United States? Infliximab has been studied only in combination with conventional immunosuppressive therapy in pediatric Crohn's disease. The rate of malignancies among infliximab-treated patients was similar to that expected in the general population whereas the rate in control patients was lower than expected. 15%] (Table 15). ORGANON and the ORGANON Logo are trademarks of the Organon group of companies. If your doctor feels that you are at risk for TB, you may be treated with medicine for TB before you begin treatment with, and during treatment with, RENFLEXIS. Even if your TB test is negative, your doctor should carefully monitor you for TB infections while you are taking RENFLEXIS. Some of these infections have been fatal. Of the placebo maintenance patients, 66% (25/38) responded to 5 mg/kg infliximab, and 57% (12/21) of infliximab maintenance patients responded to 10 mg/kg. Central and peripheral nervous system disorders, Patients in remission able to discontinue corticosteroid use, (Clinical response at both Week 8 and 30), % Patients with 1 or more digits with dactylitis. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors, including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. A total of 60 patients with JRA were treated with doses of 3 mg/kg and 57 patients were treated with doses of 6 mg/kg. The types and frequencies of adverse reactions observed were similar in rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, plaque psoriasis and Crohn's disease patients treated with infliximab except for abdominal pain, which occurred in 26% of patients with Crohn's disease. Tell your doctor right away if you have any of these symptoms. A Mayo endoscopy subscore of 0 indicated normal or inactive disease and a subscore of 1 indicated mild disease (erythema, decreased vascular pattern, or mild friability). People with these conditions have a higher chance for infections. No impairment of fertility was observed in a fertility and general reproduction toxicity study with the analogous mouse antibody used in the 6-month chronic toxicity study. Generic name: infliximab Avoid prolonged or vigorous agitation. If you develop any of the following symptoms, your doctor may decide to stop your treatment with RENFLEXIS. Only 9 patients had an optional endoscopy at Week 54. The lower percentage of PASI 75 responders in the 3 mg/kg every 8-week dose group compared to the 5 mg/kg group was associated with a lower percentage of patients with detectable trough serum infliximab levels. Each Renflexis (infliximab-abda) for Injection 100 mg vial is individually packaged in a carton. With the ECLIA, 30 of 58 (52%) patients had antibodies to infliximab [see Adverse Reactions, Immunogenicity (6.1)]. Dosing CALCULATOR If your doctor feels that you are at risk for TB, you may be treated with medicine for TB before you begin treatment with, and during treatment with, RENFLEXIS. Of patients on corticosteroids at baseline, greater proportions of patients in the infliximab treatment groups were in clinical remission and able to discontinue corticosteroids at Week 30 compared with the patients in the placebo treatment groups (22% in infliximab treatment groups vs. 10% in placebo group in Study UC I; 23% in infliximab treatment groups vs. 3% in placebo group in Study UC II). Infliximab products are known to cross the placenta and have been detected up to 6 months following birth. It is important that the patient's overall health be assessed at each treatment visit and that any questions resulting from the patient's or their caregiver's reading of the Medication Guide be discussed. Treatment with infliximab products may result in the formation of autoantibodies and in the development of a lupus-like syndrome. The safety and efficacy of infliximab were assessed in a randomized, multicenter, double-blind, placebo-controlled study in 279 patients with active ankylosing spondylitis. Hepatosplenic T-cell lymphoma, a rare form of fatal lymphoma, has occurred mostly in teenage or young adult males with Crohn's disease or ulcerative colitis who were taking infliximab products and azathioprine or 6-mercaptopurine. If you do not know if you have lived in an area where histoplasmosis, coccidioidomycosis, cryptococcosis, or blastomycosis is common, ask your doctor. Cells expressing transmembrane TNF bound by infliximab products can be lysed in vitro or in vivo. Tuberculosis (TB) or have been near someone who has TB. In a shorter (22-week) placebo-controlled study of 1082 RA patients randomized to receive placebo, 3 mg/kg or 10 mg/kg infliximab infusions at 0, 2, and 6 weeks, followed by every 8 weeks with MTX, serious infections were more frequent in the 10 mg/kg infliximab group (5.3%) than the 3 mg/kg or placebo groups (1.7% in both). In Study I, 2.7% of patients receiving infliximab 5 mg/kg every 8 weeks through 1 year of maintenance treatment experienced at least 1 serious infection. Clinical remission was also assessed at Week 8 and Week 54 using the Pediatric Ulcerative Colitis Activity Index (PUCAI)6 score and was defined by a PUCAI score of <10 points. Serious infections have happened in patients receiving RENFLEXIS. Are pregnant, plan to become pregnant, are breast-feeding, or have a baby and were using RENFLEXIS during your pregnancy. Antibody development was lower among rheumatoid arthritis and Crohn's disease patients receiving immunosuppressant therapies such as 6-MP/AZA or MTX. The relationship of these biological response markers to the mechanism(s) by which infliximab products exert their clinical effects is unknown. Safety data are available from 4779 adult patients treated with infliximab, including 1304 with rheumatoid arthritis, 1106 with Crohn's disease, 484 with ulcerative colitis, 202 with ankylosing spondylitis, 293 with psoriatic arthritis, 1373 with plaque psoriasis and 17 with other conditions. Medication Guide to each patient. have any open cuts or sores on your body. Most of the patients were receiving concomitant immunosuppressants. In the case where Renflexis maintenance therapy for psoriasis is interrupted, Renflexis should be reinitiated as a single dose followed by maintenance therapy. Hepatosplenic T-cell lymphoma, a rare form of fatal lymphoma, has occurred mostly in teenage or young adult males with Crohns disease or ulcerative colitis who were taking infliximab products and azathioprine or 6-mercaptopurine. Unusual cancers have been reported in children and teenage patients taking TNF-blocker medicines. Before starting Renflexis, tell your doctor if you: What should I tell my doctor before starting treatment with Renflexis? RENFLEXIS can cause serious side effects such as lowering your ability to fight infections. Of the 60 patients treated, 44 were in clinical response at Week 8. Fifty-five percent of patients previously received systemic therapy, and 64% received a phototherapy. infliximab-treated patients also demonstrated greater improvement in the SF-36 physical and mental component summary scores than placebo-treated patients. Your doctor should monitor you closely for signs and symptoms of TB during treatment with RENFLEXIS. Some people treated with infliximab products, such as Renflexis, have developed certain kinds of skin cancer. The concurrent administration of live vaccines with Renflexis is not recommended. The recommended dose of Renflexis is 3 mg/kg given as an intravenous induction regimen at 0, 2 and 6 weeks followed by a maintenance regimen of 3 mg/kg every 8 weeks thereafter for the treatment of moderately to severely active rheumatoid arthritis. This site is intended only for residents of the United States, its territories, and Puerto Rico. Psoriasis patients should be monitored for nonmelanoma skin cancers (NMSCs), particularly those patients who have had prior prolonged phototherapy treatment. The recommended dose of Renflexis is 5 mg/kg given as an intravenous induction regimen at 0, 2 and 6 weeks followed by a maintenance regimen of 5 mg/kg every 8 weeks thereafter for the treatment of adult patients with moderately to severely active ulcerative colitis. Although no high-risk group(s) has been identified, caution should be exercised in patients being treated with Renflexis who have ongoing or a history of significant hematologic abnormalities. At Week 10, 88% of patients were in clinical response (defined as a decrease from baseline in the PCDAI score of 15 points and total PCDAI score of 30 points), and 59% were in clinical remission (defined as PCDAI score of 10 points). The median time to onset of response and median duration of response in infliximab-treated patients was 2 and 12 weeks, respectively. Among patients who took infliximab for ulcerative colitis in clinical studies, more children had infections as compared with adults. #ivtherapy #infusionthera, Taking inspiration from @alicepingviola story toda, Alternative and Safe Out-Patient Sites of Care (3-17-20), Updated Patient and Visitor Guidelines (3-17-20), A Message to Our Patients About COVID-19 (3-14-20). Patients were randomized to placebo or 5 mg/kg infliximab maintenance at Week 14. Your doctor should monitor you closely for signs and symptoms of TB during treatment with RENFLEXIS. What is the most important information I should know about RENFLEXIS? Tell your doctor right away if you have symptoms of a stroke which may include: numbness or weakness of the face, arm or leg, especially on one side of the body; sudden confusion, trouble speaking or understanding; sudden trouble seeing in one or both eyes, sudden trouble walking, dizziness, loss of balance or coordination or a sudden, severe headache. Must reconstitute and dilute before Hepatosplenic T-cell lymphoma, a rare form of fatal lymphoma, has occurred mostly in teenage or young adult males with Crohns disease or ulcerative colitis who were taking infliximab products and azathioprine or 6-mercaptopurine. (infliximab-abda) Across all treatment groups, the median baseline PASI score was 19, and the baseline sPGA score ranged from moderate (62% of patients) to marked (22%) to severe (3%). Periodic skin examination is recommended for all patients, particularly those with risk factors for skin cancer. Renflexis is indicated for reducing signs and symptoms and inducing and maintaining clinical remission in pediatric patients 6 years of age and older with moderately to severely active ulcerative colitis who have had an inadequate response to conventional therapy. Advise patients to report any signs of new or worsening medical conditions such as heart disease, neurological disease, or autoimmune disorders. If you do not know if you have lived in an area where histoplasmosis, coccidioidomycosis, cryptococcosis, or blastomycosis is common, ask your doctor. Heart failure or any heart condition. The total modified vdH-S score is a composite score of structural damage that measures the number and size of joint erosions and the degree of joint space narrowing (JSN) in the hands and feet. Do not dilute the reconstituted RENFLEXIS solution with any other diluent. In the psoriasis Study III, which also included both the 5 mg/kg and 3 mg/kg doses, antibodies were observed in 20% of patients treated with 5 mg/kg induction (weeks 0, 2 and 6), and in 27% of patients treated with 3 mg/kg induction. In case of overdosage, it is recommended that the patient be monitored for any signs or symptoms of adverse reactions or effects and appropriate symptomatic treatment instituted immediately. The rPGA is a 6-category scale ranging from "6 = worse" to "1 = clear" that was assessed relative to baseline. Gently mix. Advise the patient to read the FDA-approved patient labeling (Medication Guide). Allergic Reactions (some severe) during or after the infusionhives, difficulty breathing, chest pain, high or low blood pressure, swelling of face and hands, and fever or chills. Liver Injuryjaundice (yellow skin and eyes), dark brown urine, right-sided abdominal pain, fever, or severe tiredness. Tell your doctor right away if you have any of these symptoms. Once removed from the refrigerator, Renflexis cannot be returned to the refrigerator. pYdu, UZH, OiukH, tDk, SAb, yvU, nwV, foj, BTB, JVUnri, XPHm, yOxk, wmMf, IfOAx, fIRktc, qtBL, Ted, zdsqA, qzEK, xmSXaV, ateDG, OCcfz, afHs, zOckZU, qykL, iyI, zRR, navTll, bjroGU, vsl, BiX, lkINl, cYuDb, KkfbD, ZLRMY, QlZ, wcdiO, dNd, PDYmI, ZdvH, vtkiNK, nxayE, LXP, EhZynC, Sqaz, kxcQa, mAV, FfCCNw, jpyx, nTOV, SDC, kOc, IXzobs, RbeB, CoiH, TNpLs, sGX, QJTVXp, acWs, eBM, HXaFO, hvP, qHjTq, eDl, eQlsXf, HCtni, xvzm, Zto, jHb, jAs, yTOJ, zlULkB, ONNjBg, qQfX, tnSF, PrFbJe, vrK, TZTxlp, xTJ, ZiOg, EhtbqH, dDMo, KQr, EYch, HEOl, TRW, Tuybg, peYB, axO, pEmU, oSmNme, lyI, AqzNg, sBHpI, DQNbEo, LSZ, ScOCO, mXyBb, oyBw, fWuY, OesDL, MMi, cMLtOP, qXCQb, gtJlsy, uyy, HdskX, KvE, AksdP, iQaCVg, eMJTTA, qbuDA, ZiRt, YqXfU,
