• Most common adverse reactions (≥20%) include neutropenia, diarrhea, nausea, anemia, upper respiratory tract infection, thrombocytopenia, and fatigue

• Anticipate TLS 1. Assess risk in all patients 2. Premedicate with antihyperuricemics and ensure adequate hydration 3. Employ more intensive measures (IV hydration, frequent monitoring, hospitalization) as overall TLS risk increases

• Monitor for neutropenia, with medical management as appropriate Summary Thoughts on Novel Agent Classes in CLL

1. BTK inhibitors: Increasingly an option across the spectrum of CLL treatment settings − Ibrutinib: approved broadly in CLL; combination studies underway − Acalabrutinib: active, potential role in BTK-intolerant CLL; phase 3 studies in newly diagnosed and relapsed settings

2. PI3K inhibitors: Idelalisib approved; duvelisib with phase 3 data; umbralisib emerging

3. Anti-CD20 mAbs: − Obinutuzumab, ofatumumab active in CLL, applications in older patients with comorbid illnesses – Ublituximab being assessed in phase 3 trials

4. Bcl-2: Venetoclax is highly active in relapsed CLL; intriguing combination data

• Multiple new novel agents have activity in untreated and relapsed follicular lymphoma

• Individualization of therapy is becoming more and more relevant and should include discussions on: – Goals and length of therapy – Toxicity/efficacy tradeoffs – Patient preferences and $

• Next generation of studies will focus on personalization of therapy and combination regimens ... stay tuned Insights on Treatment Choices in Moving Beyond Conventional Care

NCCN Clinical Practice Guidelines in Oncology. B-Cell Lymphomas. Version 4.2018. BTK Inhibitors: Ibrutinib and Acalabrutinib Targeting BCR Signaling Bruton’s Tyrosine Kinase (BTK)

• Member of the Tec family of kinases • Roles in signaling (eg, BCR, TLR), as well as transcription • Leads to activation of PI3K, PLCγ2, MAPK, and NFκΒ pathways • BTK-deficient models predominantly have a B-cell phenotype – XID (BTK mutant) mouse: Diminished B cells, B1 lymphocytes, and impaired BCR signaling. Modest effect on other immune effector cells (NK, monocyte, macrophage, dendritic cells) due to redundancy of TEC family members – BTK knockout mouse: More profound B-cell defect due to loss of chaperone and transcriptional function • BTK mutations in humans give rise to X-linked agammaglobulinemia, an inherited disorder with decreased IgG and an absence of B cells Ibrutinib Pivotal Phase 2 Study of Ibrutinib in MCL1,2

Ibrutinib and acalabrutinib are both FDA approved for ≥2nd-line therapy

• Considerations when selecting treatment with BTK inhibitors

 Ibrutinib patients more heavily pretreated (3 vs 2 prior tx)  Different response criteria used to judge CR  Differing adverse event profiles  Weigh patient characteristics (eg, history of cardiac events, AFib) and prior treatment when deciding on therapy Immunomodulatory Agent: Lenalidomide Immunomodulatory Agents for MCL: Lenalidomide

• Lenalidomide, approved for use in MCL that has relapsed or progressed after 2 prior therapies (one of which included bortezomib), has shown efficacy as monotherapy and in combination with rituximab
