Written in Blood PERSPECTIVES “These findings confirm associations between non–catheter- related VTE and cancer type, low hemoglobin, and increased leukocyte count. These factors are already used in risk-scoring algorithms like the Khorana Risk Score for VTE, but the re- searchers also observed increased VTE risk with advanced age and previous VTE history – factors that are associated with VTE in patients without cancer. Incorporation of these risk factors into algorithms may increase the ability to identify ‘at-risk’ patients with cancer for increased surveillance or prophylactic anticoagulation. Because this study was not designed to iden- tify VTE mechanisms, future work should aim to understand how a patient’s risk factors interact with prothrombotic signals from the tumor and the central venous access device to increase thrombotic risk at different locations.” Alisa Wolberg, PhD Department of Pathology and Laboratory Medicine University of North Carolina School of Medicine Chapel Hill, NC COPIKTRA (duvelisib) Capsules, for oral use BRIEF SUMMARY OF PRESCRIBING INFORMATION - CONSULT PACKAGE INSERT FOR FULL PRESCRIBING INFORMATION WARNING: FATAL AND SERIOUS TOXICITIES: INFECTIONS, DIARRHEA OR COLITIS, CUTANEOUS REACTIONS, and PNEUMONITIS • Fatal and/or serious infections occurred in 31% of COPIKTRA-treated patients.

INDICATIONS AND USAGE 1.1 Chronic Lymphocytic Leukemia (CLL)/Small Lymphocytic Lymphoma (SLL) COPIKTRA is indicated for the treatment of adult patients with relapsed or refractory CLL or SLL after at least two prior therapies. 1.2 Follicular Lymphoma (FL) COPIKTRA is indicated for the treatment of adult patients with relapsed or refractory FL after at least two prior systemic therapies. This indication is approved under accelerated approval based on overall response rate (ORR) [see Clinical Studies (14.2)]; continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials. 3 DOSAGE FORMS AND STRENGTHS Strength Description 25 mg White to off-white opaque and Swedish orange opaque capsule printed in black ink with “duv 25 mg” 15 mg Pink opaque capsule printed in black ink with “duv 15 mg” 4 CONTRAINDICATIONS None. 5 WARNINGS AND PRECAUTIONS 5.1 Infections Serious, including fatal (18/442; 4%), infections occurred in 31% of patients receiving COPIKTRA 25 mg BID (N = 442). The most common serious infections were pneumonia, sepsis, and lower respiratory infections. Median time to onset of any grade infection was 3 months (range: 1 day to 32 months), with 75% of cases occurring within 6 months. Treat infections prior to initiation of COPIKTRA. Advise patients to report any new or worsening signs and symptoms of infection. For grade 3 or higher infection, withhold COPIKTRA until infection has resolved. Resume COPIKTRA at the same or reduced dose [see Dosage and Administration (2.3)]. Serious, including fatal, Pneumocystis jirovecii pneumonia (PJP) occurred in 1% of patients taking COPIKTRA. Provide prophylaxis for PJP during treatment with COPIKTRA. Following completion of COPIKTRA treatment, continue PJP prophylaxis until the absolute CD4+ T cell count is greater than 200 cells/μL. Withhold COPIKTRA in patients with suspected PJP of any grade, and permanently discontinue if PJP is confirmed. CMV reactivation/ infection occurred in 1% of patients taking COPIKTRA. Consider prophylactic antivirals during COPIKTRA treatment to prevent CMV infection including CMV reactivation. For clinical CMV infection or viremia, withhold COPIKTRA until infection or viremia resolves. If COPIKTRA is resumed, administer the same or reduced dose and monitor patients for CMV reactivation by PCR or antigen test at least monthly [see Dosage and Administration (2.3)]. 5.2 Diarrhea or Colitis Serious, including fatal (1/442; <1%), diarrhea or colitis occurred in 18% of patients receiving COPIKTRA 25 mg BID (N = 442). The median time to onset of any grade diarrhea or colitis was 4 months (range: 1 day to 33 months), with 75% of cases occurring by 8 months. The median event duration was 0.5 months (range: 1 day to 29 months; 75 th percentile: 1 month). Advise patients to report any new or worsening diarrhea. For non-infectious diarrhea or colitis, follow the guidelines. For patients presenting with mild or moderate diarrhea (Grade 1-2) (i.e. up to 6 stools per day over baseline) or asymptomatic (Grade 1) colitis, initiate supportive care with antidiarrheal agents as appropriate, continue COPIKTRA at the current dose, and monitor the patient at least weekly until the event resolves. If the diarrhea is unresponsive to antidiarrheal therapy, withhold COPIKTRA and initiate supportive therapy with also may be limited by the use of prophy- lactic anticoagulation among patients per- ceived to have a higher risk of VTE, which may have affected the observed VTE rate. These authors report no conflicts of interest. REFERENCE Decousus H, Bourmaud A, Fournel P, et al; for the ONCOCIP Investigators.

Monitor the patient at least weekly. Upon resolution of the diarrhea, consider restarting COPIKTRA at a reduced dose. For patients presenting with abdominal pain, stool with mucus or blood, change in bowel habits, peritoneal signs or with severe diarrhea (Grade 3) (i.e. > 6 stools per day over baseline) withhold COPIKTRA and initiate supportive therapy with enteric acting steroids (e.g. budesonide) or systemic steroids. A diagnostic work-up to determine etiology, including colonoscopy, should be performed. Monitor at least weekly. Upon resolution of the diarrhea or colitis, restart COPIKTRA at a reduced dose. For recurrent Grade 3 diarrhea or recurrent colitis of any grade, discontinue COPIKTRA. Discontinue COPIKTRA for life-threatening diarrhea or colitis [see Dosage and Administration (2.3)]. 5.3 Cutaneous Reactions Serious, including fatal (2/442; <1%), cutaneous reactions occurred in 5% of patients receiving COPIKTRA 25 mg BID (N = 442). Fatal cases included drug reaction with eosinophilia and systemic symptoms (DRESS) and toxic epidermal necrolysis (TEN). Median time to onset of any grade cutaneous reaction was 3 months (range: 1 day to 29 months, 75 th percentile: 6 months), with a median event duration of 1 month (range: 1 day to 37 months, 75 th percentile: 2 months). Presenting features for the serious events were primarily described as pruritic, erythematous, or maculo- papular. Less common presenting features include exanthem, desquamation, erythroderma, skin exfoliation, keratinocyte necrosis, and papular rash. Advise patients to report any new or worsening cutaneous reactions. Review all concomitant medications and discontinue any medications potentially contributing to the event. For patients presenting with mild or moderate (Grade 1-2) cutaneous reactions, continue COPIKTRA at the current dose, initiate supportive care with emollients, anti-histamines (for pruritus), or topical steroids, and monitor the patient closely. Withhold COPIKTRA for severe (Grade 3) cutaneous reaction until resolution. Initiate supportive care with steroids (topical or systemic) or anti-histamines (for pruritus). Monitor at least weekly until resolved. Upon resolution of the event, restart COPIKTRA at a reduced dose. Discontinue COPIKTRA if severe cutaneous reaction does not improve, worsens, or recurs. For life-threatening cutaneous reactions, discontinue COPIKTRA. In patients with SJS, TEN, or DRESS of any grade, discontinue COPIKTRA [see Dosage and Administration (2.3)]. 5.4 Pneumonitis Serious, including fatal (1/442; <1%), pneumonitis without an apparent infectious cause occurred in 5% of patients receiving COPIKTRA 25 mg BID (N = 442). Median time to onset of any grade pneumonitis was 4 months (range: 9 days to 27 months), with 75% of cases occurring within 9 months. The median event duration was 1 month, with 75% of cases resolving by 2 months. Withhold COPIKTRA in patients who present with new or progressive pulmonary signs and symptoms such as cough, dyspnea, hypoxia, interstitial infiltrates on a radiologic exam, or a decline by more than 5% in oxygen saturation and evaluate for etiology. If the pneumonitis is infectious, patients may be restarted on COPIKTRA at the previous dose once the infection, pulmonary signs and symptoms resolve. For moderate non-infectious pneumonitis (Grade 2), treat with systemic corticosteroids, and resume COPIKTRA at a reduced dose upon resolution. If non-infectious pneumonitis recurs or does not respond to steroid therapy, discontinue COPIKTRA. For severe or life-threatening non-infectious pneumonitis, discontinue COPIKTRA and treat with systemic steroids [see Dosage and Administration (2.3)]. 5.5 Hepatotoxicity Grade 3 and 4 ALT and/or AST elevation developed in 8% and 2%, respectively, in patients receiving COPIKTRA 25 mg BID (N=442). Two percent of patients had both an ALT or AST greater than 3 x ULN and total bilirubin greater than 2 x ULN. Median time to onset of any grade transaminase elevation was 2 months (range: 3 days to 26 months), with a median event duration of 1 month (range: 1 day to 16 months). Monitor hepatic function during treatment with COPIKTRA. For Grade 2 ALT/AST elevation (greater than 3 to 5 × ULN), maintain COPIKTRA dose and monitor at least weekly until return to less than 3 × ULN. For Grade 3 ALT/AST elevation (greater than 5 to 20 × ULN), withhold COPIKTRA and monitor at least weekly until return to less than 3 × ULN. Resume COPIKTRA at the same dose (first occurrence) or at a reduced dose for subsequent occurrence. For grade 4 ALT/AST elevation (greater than 20 × ULN) discontinue COPIKTRA [see Dosage and Administration (2.3)]. 5.6 Neutropenia Grade 3 or 4 neutropenia occurred in 42% of patients receiving COPIKTRA 25 mg BID (N = 442), with Grade 4 neutropenia occurring in 24% of all patients. The median time to onset of Grade ≥ 3 neutropenia was 2 months (range: 3 days to 31 months), with 75% of cases occurring within 4 months. Monitor neutrophil counts at least every 2 weeks for the first 2 months of COPIKTRA therapy, and at least weekly in patients with neutrophil counts < 1.0 Gi/L (Grade 3-4). Withhold COPIKTRA in patients presenting with neutrophil counts < 0.5 Gi/L (Grade 4). Monitor until ANC is > 0.5 Gi/L, resume COPIKTRA at same dose for the first occurrence or a reduced dose for subsequent occurrence [see Dosage and Administration (2.3)].
