FDA approved in relapsed FL after ≥2 systemic therapies Imagine what’s possible: ZYDELIG®—A first-in-class PI3Kδ inhibitor ZYDELIG is the FIRST AND ONLY KINASE INHIBITOR APPROVED IN FL. NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®) RECOMMEND IDELALISIB MONOTHERAPY AS AN OPTION for appropriate patients with relapsed/refractory FL.1* ALT=alanine aminotransferase; AST=aspartate aminotransferase; NCCN®=National Comprehensive Cancer Network®. *Please see the complete version of the NCCN Guidelines® for Non-Hodgkin’s Lymphomas available on NCCN.org for specific recommendations. IMPORTANT SAFETY INFORMATION (cont'd) Contraindications • History of serious allergic reactions, including anaphylaxis and toxic epidermal necrolysis (TEN) Warnings and Precautions • Hepatotoxicity: Findings were generally observed within the first 12 weeks of treatment and reversed with dose interruption. Upon rechallenge at a lower dose, ALT/AST elevations recurred in 26% of patients. In all patients, monitor ALT/AST every 2 weeks for the first 3 months, every 4 weeks for the next 3 months, and every 1 to 3 months thereafter. If ALT/AST is >3× upper limit of normal (ULN), monitor for liver toxicity weekly. If ALT/AST is >5× ULN, withhold ZYDELIG and monitor ALT/AST and total bilirubin weekly until resolved. Discontinue ZYDELIG for recurrent hepatotoxicity. Avoid concurrent use with other hepatotoxic drugs • Severe diarrhea or colitis: Grade 3+ diarrhea can occur at any time and responds poorly to antimotility agents. Avoid concurrent use with other drugs that cause diarrhea • Pneumonitis: Evaluate for pneumonitis in patients presenting with pulmonary symptoms such as cough, dyspnea, hypoxia, interstitial infiltrates on radiologic exam, or oxygen saturation decline by ≥5% • Intestinal perforation: Advise patients to promptly report any new or worsening abdominal pain, chills, fever, nausea, or vomiting • Severe cutaneous reactions: One case of TEN occurred in a study of ZYDELIG in combination with rituximab and bendamustine. Other severe or life-threatening (grade ≥3) cutaneous reactions have been reported. Monitor patients for the development of severe cutaneous reactions and discontinue ZYDELIG if a reaction occurs • Anaphylaxis: Serious allergic reactions including anaphylaxis have been reported. Discontinue ZYDELIG permanently and institute appropriate supportive measures if a reaction occurs • Neutropenia: Treatment-emergent grade 3-4 neutropenia occurred in 31% of ZYDELIG-treated patients in clinical trials. In all patients, monitor blood counts ≥every 2 weeks for the first 3 months. In patients with neutrophil counts <1.0 Gi/L, monitor weekly • Embryo-fetal toxicity: ZYDELIG may cause fetal harm.
