NINLARO should be taken once a week on the same day and at approximately the same time for the first three weeks of a four week cycle. The importance of carefully following all dosage instructions should be discussed with patients starting treatment. Instruct patients to take the recommended dosage as directed, because overdosage has led to deaths [see Overdosage (10) ] . NINLARO should be taken at least one hour before or at least two hours after food [see Clinical Pharmacology (12.3) ] . The whole capsule should be swallowed with water. The capsule should not be crushed, chewed or opened [see How Supplied/Storage and Handling (16) ] . If a NINLARO dose is delayed or missed, the dose should be taken only if the next scheduled dose is ≥72 hours away. A missed dose should not be taken within 72 hours of the next scheduled dose. A double dose should not be taken to make up for the missed dose. If vomiting occurs after taking a dose, the patient should not repeat the dose. The patient should resume dosing at the time of the next scheduled dose. Prior to initiating a new cycle of therapy: Absolute neutrophil count should be at least 1,000/mm 3 Platelet count should be at least 75,000/mm 3 Non-hematologic toxicities should, at the healthcare provider's discretion, generally be recovered to patient's baseline condition or Grade 1 or lower Treatment should be continued until disease progression or unacceptable toxicity. Concomitant Medications Consider antiviral prophylaxis in patients being treated with NINLARO to decrease the risk of herpes zoster reactivation [see Adverse Reactions (6.1) ] . 2.2 Dosage Modification Guidelines The NINLARO dose reduction steps are presented in Table 2 and the dosage modification guidelines are provided in Table 3. Table 2: NINLARO Dose Reductions due to Adverse Reactions Recommended starting dose Recommended starting dose of 3 mg in patients with moderate or severe hepatic impairment, severe renal impairment or end-stage renal disease requiring dialysis [see Dosage and Administration (2.3 , 2.4) ] . First reduction to Second reduction to Discontinue 4 mg 3 mg 2.3 mg An alternating dose modification approach is recommended for NINLARO and lenalidomide for thrombocytopenia, neutropenia, and rash as described in Table 3. Refer to the lenalidomide prescribing information if dose reduction is needed for lenalidomide. Table 3: Dosage Modifications Guidelines for NINLARO in Combination with Lenalidomide and Dexamethasone Hematological Toxicities Recommended Actions Thrombocytopenia (Platelet Count) Platelet count less than 30,000/mm 3 Withhold NINLARO and lenalidomide until platelet count is at least 30,000/mm 3 . Following recovery, resume lenalidomide at the next lower dose according to its prescribing information and resume NINLARO at its most recent dose. If platelet count falls to less than 30,000/mm 3 again, withhold NINLARO and lenalidomide until platelet count is at least 30,000/mm 3 . Following recovery, resume NINLARO at the next lower dose and resume lenalidomide at its most recent dose. For additional occurrences, alternate dose modification of lenalidomide and NINLARO Neutropenia (Absolute Neutrophil Count) Absolute neutrophil count less than 500/mm 3 Withhold NINLARO and lenalidomide until absolute neutrophil count is at least 500/mm 3 . Consider adding G-CSF as per clinical guidelines. Following recovery, resume lenalidomide at the next lower dose according to its prescribing information and resume NINLARO at its most recent dose. If absolute neutrophil count falls to less than 500/mm 3 again, withhold NINLARO and lenalidomide until absolute neutrophil count is at least 500/mm 3 . Following recovery, resume NINLARO at the next lower dose and resume lenalidomide at its most recent dose. Non-Hematological Toxicities Recommended Actions Rash Grade Grading based on National Cancer Institute Common Terminology Criteria (CTCAE) Version 4.03 2 or 3 Withhold lenalidomide until rash recovers to Grade 1 or lower. Following recovery, resume lenalidomide at the next lower dose according to its prescribing information. If Grade 2 or 3 rash occurs again, withhold NINLARO and lenalidomide until rash recovers to Grade 1 or lower. Following recovery, resume NINLARO at the next lower dose and resume lenalidomide at its most recent dose. Grade 4 Discontinue treatment regimen. Peripheral Neuropathy Grade 1 Peripheral Neuropathy with Pain or Grade 2 Peripheral Neuropathy Withhold NINLARO until peripheral neuropathy recovers to Grade 1 or lower without pain or patient's baseline. Following recovery, resume NINLARO at its most recent dose. Grade 2 Peripheral Neuropathy with Pain or Grade 3 Peripheral Neuropathy Withhold NINLARO. Toxicities should, at the healthcare provider's discretion, generally recover to patient's baseline condition or Grade 1 or lower prior to resuming NINLARO. Following recovery, resume NINLARO at the next lower dose. Grade 4 Peripheral Neuropathy Discontinue treatment regimen. Other Non-Hematological Toxicities Other Grade 3 or 4 Non-Hematological Toxicities Withhold NINLARO. Toxicities should, at the healthcare provider's discretion, generally recover to patient's baseline condition or Grade 1 or lower prior to resuming NINLARO. If attributable to NINLARO, resume NINLARO at the next lower dose following recovery. 2.3 Dosage in Patients with Hepatic Impairment Reduce the starting dose of NINLARO to 3 mg in patients with moderate (total bilirubin greater than 1.5-3 × ULN) or severe (total bilirubin greater than 3 × ULN) hepatic impairment [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3) ] . 2.4 Dosage in Patients with Renal Impairment Reduce the starting dose of NINLARO to 3 mg in patients with severe renal impairment (creatinine clearance less than 30 mL/min) or end-stage renal disease (ESRD) requiring dialysis. NINLARO is not dialyzable and therefore can be administered without regard to the timing of dialysis [see Use in Specific Populations (8.7) and Clinical Pharmacology (12.3) ] . Refer to the lenalidomide prescribing information for dosing recommendations in patients with renal impairment.

( 5.9 ) 5.1 Thrombocytopenia Thrombocytopenia has been reported with NINLARO with platelet nadirs typically occurring between Days 14-21 of each 28-day cycle and recovery to baseline by the start of the next cycle [see Adverse Reactions (6.1) ] . Grade 3 thrombocytopenia was reported in 17% of patients in the NINLARO regimen and Grade 4 thrombocytopenia was reported in 13% in the NINLARO regimen. The rate of platelet transfusions was 10% in the NINLARO regimen and 7% in the placebo regimen. Monitor platelet counts at least monthly during treatment with NINLARO. Consider more frequent monitoring during the first three cycles. Manage thrombocytopenia with dose modifications [see Dosage and Administration (2.2) ] and platelet transfusions as per standard medical guidelines. 5.2 Gastrointestinal Toxicities Diarrhea, constipation, nausea, and vomiting have been reported with NINLARO, occasionally requiring use of antidiarrheal and antiemetic medications, and supportive care. Diarrhea was reported in 52% of patients in the NINLARO regimen and 43% in the placebo regimen, constipation in 35% and 28%, respectively, nausea in 32% and 23%, respectively, and vomiting in 26% and 13%, respectively. Diarrhea resulted in discontinuation of one or more of the three drugs in 3% of patients in the NINLARO regimen and 2% of patients in the placebo regimen [see Adverse Reactions (6.1) ] . Adjust dosing for Grade 3 or 4 symptoms [see Dosage and Administration (2.2) ] . 5.3 Peripheral Neuropathy The majority of peripheral neuropathy adverse reactions were Grade 1 (18% in the NINLARO regimen and 16% in the placebo regimen) and Grade 2 (11% in the NINLARO regimen and 6% in the placebo regimen) [see Adverse Reactions (6.1) ] . Grade 3 adverse reactions of peripheral neuropathy were reported at 2% in both regimens. The most commonly reported reaction was peripheral sensory neuropathy (24% and 17% in the NINLARO and placebo regimen, respectively). Peripheral motor neuropathy was not commonly reported in either regimen (<1%). Peripheral neuropathy resulted in discontinuation of one or more of the three drugs in 4% of patients in the NINLARO regimen and <1% of patients in the placebo regimen. Patients should be monitored for symptoms of neuropathy. Patients experiencing new or worsening peripheral neuropathy may require dose modification [see Dosage and Administration (2.2) ] . 5.4 Peripheral Edema Peripheral edema was reported in 27% and 21% of patients in the NINLARO and placebo regimens, respectively. The majority of peripheral edema adverse reactions were Grade 1 (17% in the NINLARO regimen and 14% in the placebo regimen) and Grade 2 (7% in the NINLARO regimen and 6% in the placebo regimen). Grade 3 peripheral edema was reported in 2% and 1% of patients in the NINLARO and placebo regimens, respectively [see Adverse Reactions (6.1) ] . Peripheral edema resulted in discontinuation of one or more of the three drugs in <1% of patients in both regimens. Evaluate for underlying causes and provide supportive care, as necessary. Adjust dosing of dexamethasone per its prescribing information or NINLARO for Grade 3 or 4 symptoms [see Dosage and Administration (2.2) ] . 5.5 Cutaneous Reactions Rash was reported in 27% of patients in the NINLARO regimen and 16% of patients in the placebo regimen. The majority of the rash adverse reactions were Grade 1 (15% in the NINLARO regimen and 9% in the placebo regimen) or Grade 2 (9% in the NINLARO regimen and 4% in the placebo regimen) [see Adverse Reactions (6.1) ] . Grade 3 rash was reported in 3% of patients in the NINLARO regimen and 2% of patients in the placebo regimen. Serious adverse reactions of rash were reported in <1% of patients in the NINLARO regimen. The most common type of rash reported in both regimens included maculo-papular and macular rash. Rash resulted in discontinuation of one or more of the three drugs in <1% of patients in both regimens. Manage rash with supportive care or with dose modification if Grade 2 or higher [see Dosage and Administration (2.2) ] . Stevens-Johnson syndrome and toxic epidermal necrolysis, including fatal cases, have been reported with NINLARO [see Adverse Reactions (6.1 , 6.2 )] . If Stevens-Johnson syndrome or toxic epidermal necrolysis occurs, discontinue NINLARO and manage as clinically indicated. 5.6 Thrombotic Microangiopathy Cases, sometimes fatal, of thrombotic microangiopathy, including thrombotic thrombocytopenic purpura/hemolytic uremic syndrome (TTP/HUS), have been reported in patients who received NINLARO [see Adverse Reactions (6.1) ] . Monitor for signs and symptoms of TTP/HUS. If the diagnosis is suspected, stop NINLARO and evaluate. If the diagnosis of TTP/HUS is excluded, consider restarting NINLARO. The safety of reinitiating NINLARO therapy in patients previously experiencing TTP/HUS is not known. 5.7 Hepatotoxicity Drug-induced liver injury, hepatocellular injury, hepatic steatosis, hepatitis cholestatic and hepatotoxicity have each been reported in <1% of patients treated with NINLARO [see Adverse Reactions (6.1) ] . Hepatotoxicity has been reported (10% in the NINLARO regimen and 9% in the placebo regimen). Monitor hepatic enzymes regularly and adjust dosing for Grade 3 or 4 symptoms [see Dosage and Administration (2.2) ] . 5.8 Embryo-Fetal Toxicity NINLARO can cause fetal harm when administered to a pregnant woman based on the mechanism of action and findings in animal studies. Ixazomib caused embryo-fetal toxicity in pregnant rats and rabbits at doses resulting in exposures that were slightly higher than those observed in patients receiving the recommended dose. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective non-hormonal contraception during treatment with NINLARO and for 90 days following the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with NINLARO and for 90 days following the last dose [see Drug Interactions (7.1) and Use in Specific Populations (8.1 , 8.3) ] . 5.9 Increased Mortality in Patients Treated with NINLARO in the Maintenance Setting In two prospective randomized clinical trials in multiple myeloma in the maintenance setting, treatment with NINLARO resulted in increased deaths. Treatment of patients with NINLARO for multiple myeloma in the maintenance setting is not recommended outside of controlled trials [see Clinical Studies (14.2) ] .

The following adverse reactions are described in detail in other sections of the prescribing information: Thrombocytopenia [see Warnings and Precautions (5.1) ] Gastrointestinal Toxicities [see Warnings and Precautions (5.2) ] Peripheral Neuropathy [see Warnings and Precautions (5.3) ] Peripheral Edema [see Warnings and Precautions (5.4) ] Cutaneous Reactions [see Warnings and Precautions (5.5) ] Thrombotic Microangiopathy [see Warnings and Precautions (5.6) ] Hepatotoxicity [see Warnings and Precautions (5.7) ] The most common adverse reactions (≥20%) are thrombocytopenia, neutropenia, diarrhea, constipation, peripheral neuropathy, nausea, peripheral edema, rash, vomiting, and bronchitis. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Takeda Pharmaceuticals at 1-844-617-6468 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety population from the randomized, double-blind, placebo-controlled clinical study included 720 patients with relapsed and/or refractory multiple myeloma, who received NINLARO in combination with lenalidomide and dexamethasone (NINLARO regimen; N=361) or placebo in combination with lenalidomide and dexamethasone (placebo regimen; N=359). The most frequently reported adverse reactions (≥20% with a difference of ≥5% compared to placebo) in the NINLARO regimen were thrombocytopenia, neutropenia, diarrhea, constipation, peripheral neuropathy, nausea, peripheral edema, rash, vomiting, and bronchitis. Serious adverse reactions reported in ≥2% of patients in the NINLARO regimen included diarrhea (3%), thrombocytopenia (2%) and bronchitis (2%). One or more of the three drugs was permanently discontinued in 4% of patients reporting peripheral neuropathy, 3% of patients reporting diarrhea and 2% of patients reporting thrombocytopenia. Permanent discontinuation of NINLARO due to an adverse reaction occurred in 10% of patients. Table 4 summarizes the non-hematologic adverse reactions occurring in at least 5% of patients with at least a 5% difference between the NINLARO regimen and the placebo regimen.

Antiviral prophylaxis was allowed at the healthcare provider's discretion. Patients treated in the NINLARO regimen who received antiviral prophylaxis had a lower incidence (1%) of herpes zoster infection compared to patients who did not receive prophylaxis (10%). Eye Disorders Eye disorders were reported with many different preferred terms but in aggregate, the frequency was 38% in patients in the NINLARO regimen. The most common adverse reactions of the eyes were cataract (15%), conjunctivitis (9%), blurred vision (7%), and dry eye (6%). Other Clinical Trials Experience The following serious adverse reactions have each been reported at a frequency of <1% in patients treated with NINLARO: acute febrile neutrophilic dermatosis (Sweet's syndrome), Stevens-Johnson syndrome, transverse myelitis, posterior reversible encephalopathy syndrome, tumor lysis syndrome, and thrombotic thrombocytopenic purpura. 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of NINLARO. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Immune system disorders: Angioedema Skin and subcutaneous tissue disorders: Toxic epidermal necrolysis

8.1 Pregnancy Risk Summary Based on its mechanism of action [see Clinical Pharmacology (12.1) ] and data from animal reproduction studies, NINLARO can cause fetal harm when administered to a pregnant woman. There are no available data on NINLARO use in pregnant women to evaluate drug-associated risk. Ixazomib caused embryo-fetal toxicity in pregnant rats and rabbits at doses resulting in exposures that were slightly higher than those observed in patients receiving the recommended dose (see Data ) . Advise pregnant women of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Animal Data In an embryo-fetal development study in pregnant rabbits there were increases in fetal skeletal variations/abnormalities (fused caudal vertebrae, number of lumbar vertebrae, and full supernumerary ribs) at doses that were also maternally toxic (≥0.3 mg/kg). Exposures in the rabbit at 0.3 mg/kg were 1.9 times the clinical time averaged exposures at the recommended dose of 4 mg. In a rat dose range-finding embryo-fetal development study, at doses that were maternally toxic, there were decreases in fetal weights, a trend towards decreased fetal viability, and increased post-implantation losses at 0.6 mg/kg. Exposures in rats at the dose of 0.6 mg/kg was 2.5 times the clinical time averaged exposures at the recommended dose of 4 mg.
