Baricitinib: Immunosuppressants may enhance the immunosuppressive effect of Baricitinib. In aHUS, mutations in complement pathway genes, such as CFH, MCP (CD46), and CFI, lead to the uncontrolled activation of the alternative complement pathway, leading to thrombotic microangiopathy (TMA)or blood clots in small blood vessels. Unresolved Neisseria meningitidis infection; patients not currently vaccinated against N. meningitidis, unless the risks of delaying ravulizumab treatment outweigh the risks of developing a meningococcal infection. Ravulizumab inhibits terminal complement-mediated intravascular hemolysis in paroxysmal nocturnal hemoglobinuria (PNH… If hemolysis signs/symptoms (including elevated LDH) occur after discontinuation, consider restarting ravulizumab treatment. A drug similar to ravulizumab (ALXN1210), called eculizumab, is currently approved for the treatment of PNH in 46 countries under the brand name Soliris®. Monoclonal antibody agents like ravulizumab are not expected to generate toxic metabolites as they generally undergo proteolysis to their constituent amino acids [F94]. Withdraw the calculated volume of ravulizumab solution from vial(s) and dilute in an infusion bag using sodium chloride 0.9% (NS) only to a final concentration of 5 mg/mL. After ravulizumab discontinuation for paroxysmal nocturnal hemoglobinuria: Monitor closely for ≥16 weeks (after discontinuation) to detect hemolysis and other reactions; monitor for signs/symptoms of hemolysis (eg, elevated lactate dehydrogenase [LDH] along with sudden decrease in paroxysmal nocturnal hemoglobinuria clone size or hemoglobin, or re-appearance of symptoms such as fatigue, hemoglobinuria, abdominal pain, shortness of breath [dyspnea], major adverse vascular event [including thrombosis], dysphagia, or erectile dysfunction) after discontinuation of ravulizumab treatment. Infuse maintenance dose (3,600 mg in a total volume of 720 mL) at 327 mL/hour (minimum infusion time: 2.2 hours). The risk or severity of adverse effects can be increased when Alefacept is combined with Ravulizumab.

Enrollment in the Ultomiris REMS program and additional information are available at 1-888-765-4747 or at www.ultomirisrems.com. In the ravulizumab arm, 73.6% of participants avoided transfusion and 53.6% of participants had normalization of LDH. The ULTOMIRIS 100 mg/mL formulation reduces average annual infusion time for patients with aHUS and PNH by approximately 60 percent (to approximately 45 minutes for adults in the average weight cohort) compared to the ULTOMIRIS 10 mg/mL formulation. Effects of ravulizumab upon fertility have not been studied in animals Label. Monitor closely for signs/symptoms of worsening infection (if administering ravulizumab to patients with active systemic infections). Life-threatening meningococcal infections/sepsis have occurred in patients treated with ravulizumab. The mean (SD) volume of distribution at steady state was 5.34 (0.92) L Label. This field Indicates whether this package is a sample packaging or not. Learn more about the criteria for depression. Revaccinate according to current guidelines. Specifically, the risk for serious infections may be increased. In particular, ravulizumab is currently the first and only long-acting C5 complement inhibitor that can be administered every eight weeks for the treatment of adult patients with PNH whereas eculizumab is a bi-weekly treatment 3,Label. Consider therapy modification, Leflunomide: Immunosuppressants may enhance the adverse/toxic effect of Leflunomide. Ravulizumab is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS). Infusion reactions did not require ravulizumab discontinuation. METHOD FOR SIMULTANEOUS QUANTIFICATION OF ALXN1210 AND ECULIZUMAB IN HUMAN SERUM OR URINE: International Publication Number WO 2018/183449 A1 [, Alexion Receives Early FDA Approval for ULTOMIRIS™ (Ravulizumab-cwvz) in Adults with Paroxysmal Nocturnal Hemoglobinuria (PNH) [, First in Human Single-Ascending Dose Study: Safety, Biomarker, Pharmacokinetics and Exposure-Response Relationships of ALXN1210, a Humanized Monoclonal Antibody to C5, with Marked Half-Life Extension and Potential for Significantly Longer Dosing Intervals / Blood 2015 125:4777 [. The risk or severity of adverse effects can be increased when Abatacept is combined with Ravulizumab. Frequently reported side effects of this drug. Specifically, the risk of concurrent infection may be increased. Mix gently; do not shake. Article No. Avoid combination, Cladribine: May enhance the immunosuppressive effect of Immunosuppressants. The risk or severity of adverse effects can be increased when Alirocumab is combined with Ravulizumab. That will be a good day. The mechanism of action of ravulizumab is similar to e culizumab, an antibody which also binds to C5 to prevent activation of the complement cascade. The risk or severity of adverse effects can be increased when Abciximab is combined with Ravulizumab. Dilute maintenance dose (3,600 mg) with NS 360 mL to a total volume of 720 mL. Management: Concurrent use with antirheumatic doses of methotrexate or nonbiologic disease modifying antirheumatic drugs (DMARDs) is permitted, and this warning seems particularly focused on more potent immunosuppressants. Consult drug interactions database for more detailed information. Assess immunization status prior to initiation; patients should receive meningococcal vaccine at least 2 weeks prior to treatment initiation. 1-7. In the U.S., ULTOMIRIS is available in two formulations with the same mechanism of action and consistent safety and efficacy. Females who were pregnant or planning to become pregnant were excluded from initial clinical studies (Kulasekararaj 2019; Lee 2019). If TMA complications occur after discontinuation, consider restarting ravulizumab treatment or appropriate organ-specific supportive measures. 15,16 Ravulizumab was designed via targeted substitution of 4 amino acids … LDH normalization: By week 4 (in complement-inhibitor naive patients with paroxysmal nocturnal hemoglobinuria). Infuse maintenance dose (2,700 mg in a total volume of 540 mL) at 192 mL/hour (minimum infusion time: 2.8 hours). Dilute maintenance dose (2,100 mg) with NS 210 mL to a total volume of 420 mL. Note: Vaccinate with meningococcal vaccine at least 2 weeks prior to treatment initiation; revaccinate according to current guidelines. Paroxysmal nocturnal hemoglobinuria: Treatment of paroxysmal nocturnal hemoglobinuria in adults. Monitor therapy, Sipuleucel-T: Immunosuppressants may diminish the therapeutic effect of Sipuleucel-T. Management: Evaluate patients to see if it is medically appropriate to reduce or discontinue therapy with immunosuppressants prior to initiating sipuleucel-T therapy. Consider therapy modification, Trastuzumab: May enhance the neutropenic effect of Immunosuppressants. The extent and duration of the pharmacodynamic response in patients with PNH were exposure dependent for ravulizumab Label. To reduce the risk for meningococcal disease, consider antimicrobial prophylaxis with oral antibiotics (penicillin, or macrolides if penicillin-allergic) for the duration of ravulizumab therapy (McNamara 2017). Management: Avoid use of live organism vaccines with immunosuppressants; live-attenuated vaccines should not be given for at least 3 months after immunosuppressants. Immediate and complete inhibition of serum-free complement protein C5 (concentration of less than 0.5 mcg/mL) was observed by the end of the first ravulizumab infusion and sustained throughout the entire 26-week treatment period in all patients, both complement-inhibitor naïve and previously treated with eculizumab Label. If signs of cardiovascular instability or respiratory compromise occur, interrupt infusion and manage supportively. Comply with the most current Advisory Committee on Immunization Practices (ACIP) recommendations for meningococcal vaccination in patients with complement deficiencies. Complete terminal complement inhibition following initiation of ravulizumab treatment led to normalization of serum LDH by week 4 in complement-inhibitor naïve patients and maintained LDH normalization in patients previously treated with eculizumab Label. Meningococcal disease due to any serogroup Consider therapy modification, BCG (Intravesical): Immunosuppressants may diminish the therapeutic effect of BCG (Intravesical). In contrast, in the eculizumab arm, 66.1% of participants avoided transfusion and 49.4% of participants had normalization of LDH. Moreover, virtually all of the phase 3 trial results for ravulizumab have demonstrated the equivalent efficacy and safety established by eculizumab and that patients transition safely and effectively from using eculizumab to ravulizumab 3. Infuse maintenance dose (3,000 mg in a total volume of 600 mL) at 257 mL/hour (minimum infusion time: 2.3 hours). Meningococcal infection may become rapidly life-threatening or fatal if not recognized and treated early. Atypical hemolytic uremic syndrome: Treatment of atypical hemolytic uremic syndrome to inhibit complement-mediated thrombotic microangiopathy in adult and pediatric patients ≥1 month of age. Monitor therapy, Echinacea: May diminish the therapeutic effect of Immunosuppressants. TMA complications may be identified by clinical symptoms (changes in mental status, seizures, angina, dyspnea, thrombosis, or increasing blood pressure) in addition to ≥2 of the following laboratory values observed concurrently (and confirmed by a second measurement 28 days apart with no interruption): platelet count decreased ≥25% compared to baseline or peak count during ravulizumab treatment; serum creatinine increased ≥25% compared to baseline or to nadir during ravulizumab treatment; or lactic dehydrogenase (LDH) increased ≥25% compared to baseline or to nadir during ravulizumab treatment.
