Drug Interactions

7 DRUG INTERACTIONS CYP3A Inhibitors: Avoid co-administration with moderate or strong CYP3A inhibitors. ( 7.1 ) CYP3A Inducers: Avoid co-administration with moderate or strong CYP3A inducers. ( 7.1 ) Gastric Acid Reducing Agents: Avoid co-administration with proton pump inhibitors (PPIs). WAYRILZ should be administered at least 2 hours before taking an antacid or H2 receptor antagonist. ( 7.1 ) 7.1 Effect of Other Drugs on WAYRILZ Strong and Moderate CYP3A Inhibitors Avoid concomitant use of WAYRILZ with strong or moderate CYP3A inhibitors. If a strong or moderate CYP3A inhibitor cannot be avoided, and these inhibitors will be used short term (such as anti-infectives for seven days or less), interrupt treatment with WAYRILZ. Avoid concomitant use of grapefruit, starfruit and products containing these fruits, and Seville oranges with WAYRILZ, as these are moderate and strong inhibitors of CYP3A. Rilzabrutinib is a CYP3A substrate. Concomitant use with a strong or moderate CYP3A inhibitor increases rilzabrutinib C max and AUC [see Clinical Pharmacology (12.3) ] , which increases the risk of WAYRILZ adverse reactions. Strong and Moderate CYP3A Inducers Avoid concomitant use of WAYRILZ

Adverse Reactions

6 ADVERSE REACTIONS The following clinically important adverse reactions are described elsewhere in the labeling: Serious Infections [see Warnings and Precautions (5.1) ] Hepatotoxicity, Including Drug-Induced Liver Injury [ see Warnings and Precautions (5.2) ] Most common adverse reactions (incidence ≥10%) were diarrhea, nausea, headache, abdominal pain, and COVID-19.

The safety of WAYRILZ was evaluated in a randomized, double-blind (DB), placebo-controlled, parallel-group study (LUNA-3), in which 202 adult patients with persistent or chronic ITP received either WAYRILZ (n=133) or placebo (n=69) [see Clinical Studies (14) ] . During the 24-week DB period, the median duration of WAYRILZ exposure was 98 days (range: 22 to 182). The most common adverse r
