rhapsido

Recommended dosage is 25 mg orally twice daily with or without food. ( 2.1 ) Swallow tablets whole. Do not split, crush, or chew RHAPSIDO. ( 2.1 ) Interrupt RHAPSIDO for 3 to 7 days pre- and post-surgery. ( 2.2 ) 2.1 Recommended Dosage The recommended dosage is 25 mg taken orally twice daily with or without food. Swallow RHAPSIDO tablet whole with water. Do not split, crush, or chew RHAPSIDO. Missed Dose(s) If a dose or doses of RHAPSIDO is missed, skip the missed dose, and take the next dose at its regularly scheduled time. Do not take an extra dose(s) of RHAPSIDO to make up for a missed dose(s). 2.2 Temporary Interruption of RHAPSIDO for Surgery Interrupt treatment with RHAPSIDO for 3 to 7 days pre- and post-surgery depending upon the type of surgery and the risk of bleeding [see Warnings and Precautions (5.1), Adverse Reactions (6.1) and Drug Interactions (7.2)] .

The most common adverse reactions (incidence ≥3%) were nasopharyngitis, bleeding, headache, nausea and abdominal pain. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Novartis Pharmaceuticals Corporation at 1-888-669-6682 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse drug reaction (ADR) rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of RHAPSIDO was based on a pooled safety population from two identical clinical trials of 52 weeks duration, REMIX-1 and REMIX-2 [see Clinical Studies (14)] . The pooled safety population consisted of 912 adult patients with CSU who remain symptomatic despite H1 antihistamine treatment and who received RHAPSIDO 25 mg orally twice daily (N=606) or placebo (N=306) for 24 weeks during the double-blind, controlled treatment period of the trial. Adverse reactions that occurred at an incidence greater than or equal to 3% and more common than the placebo group from the pooled safety population (REMIX-1 and REMIX-2) during the 24-week blinded, placebo-controlled treatment period are shown in Table 1.

Strong or Moderate CYP3A4 Inhibitors: Avoid concomitant use with RHAPSIDO. ( 7.1 ) Strong or Moderate CYP3A4 Inducers: Avoid concomitant use with RHAPSIDO. ( 7.1 ) P-gp Substrates: Exposure increases where minimal concentration changes may lead to serious adverse reactions: Monitor more frequently for adverse reactions when used concomitantly with RHAPSIDO. ( 7.2 ) Antithrombotic Agents: Consider the risks and benefits of concomitant use of antithrombotic agents with RHAPSIDO. ( 7.2 ) 7.1 Effect of Other Drugs on RHAPSIDO Strong or Moderate CYP3A4 Inhibitors Avoid use of RHAPSIDO with strong or moderate CYP3A4 inhibitors. Remibrutinib is a CYP3A4 substrate. Concomitant use with a strong or moderate CYP3A4 inhibitor increases remibrutinib exposure [see Clinical Pharmacology (12.3)] , which may increase the risk of RHAPSIDO adverse reactions. Strong or Moderate CYP3A4 Inducers Avoid use of RHAPSIDO with strong or moderate CYP3A4 inducers. Remibrutinib is a CYP3A4 substrate. Concomitant use with a strong or moderate CYP3A4 inducer decreases remibrutinib exposure [see Clinical Pharmacology (12.3)] , which may decrease the efficacy of RHAPSIDO. 7.2 Effect of RHAPSIDO on Other Drugs P-gp Substrates Monitor more frequently for adverse reactions when using RHAPSIDO with P-glycoprotein (P-gp) substrates where minimal concentration changes may lead to serious adverse reactions (e.g., digoxin). Remibrutinib is a P-gp inhibitor. Remibrutinib increases exposure of P-gp substrates, which may increase the risk of adverse reactions related to P-gp substrates [see Clinical Pharmacology (12.3)] . Antithrombotic Agents Consider the risks and benefits of concomitant administration of antithrombotic agents with RHAPSIDO [see Dosage and Administration (2.2), Warnings and Precautions (5.1), and Adverse Reactions (6.1)] . No data are available on concomitant use of RHAPSIDO with anticoagulants. The concomitant use of RHAPSIDO and anticoagulants was not allowed in clinical studies. Use of the antiplatelet agents, acetyl salicylic acid at doses up to 100 mg daily or clopidogrel up to 75 mg daily, was allowed in the RHAPSIDO clinical studies.
