Interrupt or discontinue ZYDELIG as recommended [See Dosage and Administration, Warnings and Precautions]. • Fatal and serious intestinal perforation can occur in ZYDELIGtreated patients. Discontinue ZYDELIG for intestinal perforation [See Warnings and Precautions]. INDICATIONS AND USAGE: • ZYDELIG is indicated in combination with rituximab for the treatment of adults with relapsed chronic lymphocytic leukemia (CLL) for whom rituximab alone would be considered appropriate therapy due to other comorbidities. • ZYDELIG is indicated for the treatment of adults with relapsed follicular B-cell non-Hodgkin lymphoma (FL) who have received ≥2 prior systemic therapies. • ZYDELIG is indicated for the treatment of adults with relapsed small lymphocytic lymphoma (SLL) who have received ≥2 prior systemic therapies. • Accelerated approval was granted for FL and SLL based on overall response rate. An improvement in patient survival or disease related symptoms has not been established. Continued approval for these indications may be contingent upon verification of clinical benefit in confirmatory trials. See Warnings and Precautions, Adverse Reactions, and Use in Specific Populations for additional information. Adult Starting Dose: One 150 mg tablet taken orally twice daily (BID), swallowed whole with or without food. Continue treatment until disease progression or unacceptable toxicity. The optimal and safe dosing regimen for patients who required treatment longer than several months is unknown. Severe diarrhea or colitis (≥Grade 3) occurred in 14% of ZYDELIG-treated patients across clinical trials. ZYDELIG-induced diarrhea can occur at any time and responds poorly to antimotility agents. Median time to resolution ranged between 1 week and 1 month following ZYDELIG interruption with or without enteric or systemic corticosteroids. Avoid concurrent use of ZYDELIG with drugs that cause diarrhea. [See Dosage and Administration]. Fatal and serious pneumonitis occurred in ZYDELIG-treated patients. Patients taking ZYDELIG who present with pulmonary symptoms (e.g., cough, dyspnea, hypoxia, interstitial infiltrates, >5% decrease in oxygen saturation) should be evaluated for pneumonitis. If pneumonitis is suspected, withhold ZYDELIG until etiology of pulmonary symptoms has &VV
