Pancreatic Adenocarcinoma In Combination with Oxaliplatin, Fluorouracil and Leucovorin for First-Line Treatment The safety of ONIVYDE in patients with metastatic pancreatic adenocarcinoma who had not previously received chemotherapy was evaluated in NAPOLI 3 [see Clinical Studies (14) ] . Patients received ONIVYDE 50 mg/m 2 in combination with oxaliplatin 60 mg/m 2 , leucovorin 400 mg/m 2 and fluorouracil 2400 mg/m 2 over 46 hours every 2 weeks (NALIRIFOX; N=383) or nab-paclitaxel 125 mg/m 2 over 35 minutes and gemcitabine 1000 mg/m 2 over 30 minutes on Day 1, 8 and 15 of each 28-day cycle (Gem+NabP; N=387). The median duration of exposure to ONIVYDE in combination with oxaliplatin, fluorouracil, and leucovorin was 24 weeks (range: 0 to 101 weeks). Serious adverse reactions occurred in 54% of patients who received ONIVYDE in combination with oxaliplatin, fluorouracil and leucovorin.

Protocol-specified therapy consisted of ONIVYDE 70 mg/m 2 with leucovorin 400 mg/m 2 and fluorouracil 2400 mg/m 2 over 46 hours every 2 weeks (ONIVYDE/FU/LV; N=117), ONIVYDE 100 mg/m 2 every 3 weeks (N=147), or leucovorin 200 mg/m 2 and fluorouracil 2000 mg/m 2 over 24 hours weekly for 4 weeks followed by 2 week rest (FU/LV; N=134) [see Clinical Studies (14) ] . Serum bilirubin within the institutional normal range, albumin ≥ 3 g/dL, and Karnofsky Performance Status (KPS) ≥ 70 were required for study entry. The median duration of exposure was 9 weeks in the ONIVYDE/FU/LV arm, 9 weeks in the ONIVYDE monotherapy arm, and 6 weeks in the FU/LV arm. The most common adverse reactions (≥ 20%) of ONIVYDE were diarrhea, fatigue/asthenia, vomiting, nausea, decreased appetite, stomatitis, and pyrexia. The most common, severe laboratory abnormalities (≥ 10% Grade 3 or 4) were lymphopenia and neutropenia. The most common serious adverse reactions (≥ 2%) of ONIVYDE were diarrhea, vomiting, neutropenic fever or neutropenic sepsis, nausea, pyrexia, sepsis, dehydration, septic shock, pneumonia, acute renal failure, and thrombocytopenia. Adverse reactions led to permanent discontinuation of ONIVYDE in 11% of patients receiving ONIVYDE/FU/LV; the most frequent adverse reactions resulting in discontinuation of ONIVYDE were diarrhea, vomiting, and sepsis. Dose reductions of ONIVYDE for adverse reactions occurred in 33% of patients receiving ONIVYDE/FU/LV; the most frequent adverse reactions requiring dose reductions were neutropenia, diarrhea, nausea, and anemia. ONIVYDE was withheld or delayed for adverse reactions in 62% of patients receiving ONIVYDE/FU/LV; the most frequent adverse reactions requiring interruption or delays were neutropenia, diarrhea, fatigue, vomiting, and thrombocytopenia.

In NAPOLI-1, Grade 1 or 2 cholinergic symptoms other than early diarrhea occurred in 12 (4.5%) ONIVYDE-treated patients. Six of these 12 patients received atropine and in 1 of the 6 patients, atropine was administered for cholinergic symptoms other than diarrhea. Infusion Reactions : Infusion reactions, consisting of rash, urticaria, periorbital edema, or pruritus, occurring on the day of ONIVYDE administration were reported in 3% of patients receiving ONIVYDE or ONIVYDE/FU/LV. Laboratory abnormalities that occurred with higher incidence in the ONIVYDE/FU/LV arm compared to the FU/LV arm (≥5% difference) are summarized in the following table.

7 DRUG INTERACTIONS Strong CYP3A4 Inducers: Avoid the use of strong CYP3A4 inducers if possible. Substitute non-enzyme inducing therapies at least 2 weeks prior to initiation of ONIVYDE. ( 7.1 ) Strong CYP3A4 Inhibitors: Avoid the use of strong CYP3A4 or UGT1A1 inhibitors, if possible; discontinue strong CYP3A4 inhibitors at least 1 week prior to starting therapy. ( 7.2 ) 7.1 Strong CYP3A4 Inducers Following administration of non-liposomal irinotecan (i.e., irinotecan HCl), exposure to irinotecan or its active metabolite, SN-38, is substantially reduced in adult and pediatric patients concomitantly receiving the CYP3A4 enzyme-inducing anticonvulsants phenytoin and strong CYP3A4 inducers. Avoid the use of strong CYP3A4 inducers (e.g., rifampin, phenytoin, carbamazepine, rifabutin, rifapentine, phenobarbital, St. John's wort) if possible. Substitute non-enzyme inducing therapies at least 2 weeks prior to initiation of ONIVYDE therapy [see Clinical Pharmacology (12.3) ] . 7.2 Strong CYP3A4 or UGT1A1 Inhibitors Following administration of non-liposomal irinotecan (i.e., irinotecan HCl), patients receiving concomitant ketoconazole, a CYP3A4 and UGT1A1 inhibitor, have increased exposure to irinotecan and its active metabolite SN-38. Co-administration of ONIVYDE with other inhibitors of CYP3A4 (e.g., clarithromycin, indinavir, itraconazole, lopinavir, nefazodone, nelfinavir, ritonavir, saquinavir, telaprevir, voriconazole) or UGT1A1 (e.g., atazanavir, gemfibrozil, indinavir) may increase systemic exposure to irinotecan or SN-38. Avoid the use of strong CYP3A4 or UGT1A1 inhibitors if possible. Discontinue strong CYP3A4 inhibitors at least 1 week prior to starting ONIVYDE therapy [see Clinical Pharmacology (12.3) ] .

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Irinotecan liposome injection is a topoisomerase 1 inhibitor encapsulated in a lipid bilayer vesicle or liposome. Topoisomerase 1 relieves torsional strain in DNA by inducing single-strand breaks. Irinotecan and its active metabolite SN-38 bind reversibly to the topoisomerase 1-DNA complex and prevent re-ligation of the single-strand breaks, leading to exposure time-dependent double-strand DNA damage and cell death. In mice bearing human tumor xenografts, irinotecan liposome administered at irinotecan HCl-equivalent doses 5-fold lower than irinotecan HCl achieved similar intratumoral exposure of SN-38. 12.3 Pharmacokinetics The plasma pharmacokinetics of total irinotecan and total SN-38 were evaluated in patients with cancer who received ONIVYDE, as a single agent or as part of combination chemotherapy, at doses between 35 mg/m 2 and 155 mg/m 2 and concentration proportional to dose was observed. The pharmacokinetic parameters of total irinotecan and total SN-38 following the administration of ONIVYDE 70 mg/m 2 as a single agent or part of combination chemotherapy are presented in Table 7. Table 7 Summary of Geometric Mean (CV) Total Irinotecan and Total SN-38 Dose (mg/m 2 ) Descriptive Statistics Total Irinotecan Total SN-38 C max [µg/mL] AUC SS [day∙µg/mL] t 1/2 [day] V [L] C max [ng/mL] AUC SS [day∙ng/mL] V [L] AUC SS : Area under the plasma concentration curve at steady-state t 1/2 : Terminal elimination half-life V: Volume of distribution 50 Geometric Mean 25.1 37.8 1.93 3.63 2.09 12.1 3.46 CV (%) 18.5 73.6 14 33.5 42.1 46.6 35.5 70 Geometric Mean 30.8 50.4 1.87 4.23 2.64 14.7 4.06 CV (%) 19.7 75.3 26.4 28.1 64.5 58 29.4 Distribution Direct measurement of irinotecan liposome showed that 95% of irinotecan remains liposome -encapsulated, and the ratios between total and encapsulated forms did not change with time from 0 to 170 hours post-dose. The mean volume of distribution is summarized in Table 7. Plasma protein binding is <0.44% of the total irinotecan in ONIVYDE. Elimination Metabolism The metabolism of irinotecan liposome has not been evaluated. Irinotecan is subject to extensive metabolic conversion by various enzyme systems, including carboxylesterases to form the active metabolite SN-38, and UGT1A1 mediating glucuronidation of SN-38 to form the inactive glucuronide metabolite SN-38G. Irinotecan can also undergo CYP3A4-mediated oxidative metabolism to several inactive oxidation products, one of which can be hydrolyzed by carboxylesterase to release SN-38. In the population PK analysis of irinotecan liposome, UGT1A1*28 7/7 homozygous status (10.6%) had no effect on SN-38 clearance compared with patients not homozygous for UGT1A1*28 7/7. Excretion The disposition of ONIVYDE has not been elucidated in humans. Following administration of irinotecan HCl, the urinary excretion of irinotecan is 11 to 20%; SN-38, <1%; and SN-38 glucuronide, 3%. The cumulative biliary and urinary excretion of irinotecan and its metabolites (SN-38 and SN-38 glucuronide), over a period of 48 hours following administration of irinotecan HCl in two patients, ranged from approximately 25% (100 mg/m 2 ) to 50% (300 mg/m 2 ). Specific Populations Age, Sex, Ethnicity, Renal and Hepatic Impairment: The population pharmacokinetic analyses suggest that age (20 to 87 years) and BSA (1.15 to 2.88 m 2 ) had no clinically meaningful effect on the exposure of irinotecan and SN-38. Irinotecan and SN-38 AUC in female patients were 28% and 32% higher, respectively, than those in male patients. Irinotecan AUC in patients of Asian ethnicity were 32% lower than that in non-Asian patients. The exposures of irinotecan and SN-38 in patients with mild or moderate renal impairment were comparable to patients with normal renal function after adjusting for BSA. The exposures of irinotecan and SN-38 in patients with mild hepatic impairment (based on NCI score) were comparable to patients with normal hepatic function. There was insufficient data in patients with severe renal impairment (CLcr < 30 mL/min) or in patients with moderate and severe hepatic impairment to assess their effects on the exposures of irinotecan and SN-38. Increased AST/ALT had no effect on irinotecan clearance; however, increased bilirubin level was associated with lower SN‑38 clearance. SN-38 AUC was increased by 32% in patients with bilirubin level of 1.14 mg/dL (95 th of the overall population) compared with that of median bilirubin level of 0.44 mg/dL. No data are available in patients with bilirubin >2.8 mg/dL. Drug Interactions In a population pharmacokinetic analysis, the pharmacokinetics of total irinotecan and total SN-38 were not altered by the co-administration of fluorouracil/leucovorin. In Study MM‑398‑07‑02‑03 and NAPOLI-3, irinotecan AUC was decreased by 33% and SN-38 C max increased by 23% following co-administration with oxaliplatin. Following administration of irinotecan HCl, dexamethasone (moderate CYP3A4 inducer) does not alter the pharmacokinetics of irinotecan. In vitro studies indicate that irinotecan, SN-38 and another metabolite, aminopentane carboxylic acid (APC), do not inhibit cytochrome P-450 isozymes. 12.5 Pharmacogenomics Individuals who are homozygous for the UGT1A1*28 allele are at increased risk for neutropenia from irinotecan HCl. In NAPOLI-1, patients homozygous for the UGT1A1*28 allele (N=7) initiated ONIVYDE at a reduced dose of 50 mg/m 2 in combination with FU/LV. The frequency of Grade 3 or 4 neutropenia in these patients [2 of 7 (28.6%)] was similar to the frequency in patients not homozygous for the UGT1A1*28 allele who received a starting dose of ONIVYDE of 70 mg/m 2 [30 of 110 (27.3%)]. In NAPOLI-3, patients homozygous for the UGT1A1*28 allele (N = 39) initiated ONIVYDE at the same starting dose of 50 mg/m 2 as patients not homozygous for the UGT1A1*28 allele (N = 328). The frequency of Grade 3 or 4 neutropenia was 23% in patients homozygous for the UGT1A1*28 allele and 13% in patients not homozygous for the UGT1A1*28 allele. The frequency of dose reduction of ONIVYDE due to treatment-emergent adverse effects was 59% versus 51% in patients homozygous versus non-homozygous for the UGT1A1*28 allele.

12.1 Mechanism of Action Irinotecan liposome injection is a topoisomerase 1 inhibitor encapsulated in a lipid bilayer vesicle or liposome. Topoisomerase 1 relieves torsional strain in DNA by inducing single-strand breaks. Irinotecan and its active metabolite SN-38 bind reversibly to the topoisomerase 1-DNA complex and prevent re-ligation of the single-strand breaks, leading to exposure time-dependent double-strand DNA damage and cell death. In mice bearing human tumor xenografts, irinotecan liposome administered at irinotecan HCl-equivalent doses 5-fold lower than irinotecan HCl achieved similar intratumoral exposure of SN-38.

12.3 Pharmacokinetics The plasma pharmacokinetics of total irinotecan and total SN-38 were evaluated in patients with cancer who received ONIVYDE, as a single agent or as part of combination chemotherapy, at doses between 35 mg/m 2 and 155 mg/m 2 and concentration proportional to dose was observed. The pharmacokinetic parameters of total irinotecan and total SN-38 following the administration of ONIVYDE 70 mg/m 2 as a single agent or part of combination chemotherapy are presented in Table 7. Table 7 Summary of Geometric Mean (CV) Total Irinotecan and Total SN-38 Dose (mg/m 2 ) Descriptive Statistics Total Irinotecan Total SN-38 C max [µg/mL] AUC SS [day∙µg/mL] t 1/2 [day] V [L] C max [ng/mL] AUC SS [day∙ng/mL] V [L] AUC SS : Area under the plasma concentration curve at steady-state t 1/2 : Terminal elimination half-life V: Volume of distribution 50 Geometric Mean 25.1 37.8 1.93 3.63 2.09 12.1 3.46 CV (%) 18.5 73.6 14 33.5 42.1 46.6 35.5 70 Geometric Mean 30.8 50.4 1.87 4.23 2.64 14.7 4.06 CV (%) 19.7 75.3 26.4 28.1 64.5 58 29.4 Distribution Direct measurement of irinotecan liposome showed that 95% of irinotecan remains liposome -encapsulated, and the ratios between total and encapsulated forms did not change with time from 0 to 170 hours post-dose. The mean volume of distribution is summarized in Table 7. Plasma protein binding is <0.44% of the total irinotecan in ONIVYDE. Elimination Metabolism The metabolism of irinotecan liposome has not been evaluated. Irinotecan is subject to extensive metabolic conversion by various enzyme systems, including carboxylesterases to form the active metabolite SN-38, and UGT1A1 mediating glucuronidation of SN-38 to form the inactive glucuronide metabolite SN-38G. Irinotecan can also undergo CYP3A4-mediated oxidative metabolism to several inactive oxidation products, one of which can be hydrolyzed by carboxylesterase to release SN-38. In the population PK analysis of irinotecan liposome, UGT1A1*28 7/7 homozygous status (10.6%) had no effect on SN-38 clearance compared with patients not homozygous for UGT1A1*28 7/7. Excretion The disposition of ONIVYDE has not been elucidated in humans. Following administration of irinotecan HCl, the urinary excretion of irinotecan is 11 to 20%; SN-38, <1%; and SN-38 glucuronide, 3%. The cumulative biliary and urinary excretion of irinotecan and its metabolites (SN-38 and SN-38 glucuronide), over a period of 48 hours following administration of irinotecan HCl in two patients, ranged from approximately 25% (100 mg/m 2 ) to 50% (300 mg/m 2 ). Specific Populations Age, Sex, Ethnicity, Renal and Hepatic Impairment: The population pharmacokinetic analyses suggest that age (20 to 87 years) and BSA (1.15 to 2.88 m 2 ) had no clinically meaningful effect on the exposure of irinotecan and SN-38. Irinotecan and SN-38 AUC in female patients were 28% and 32% higher, respectively, than those in male patients. Irinotecan AUC in patients of Asian ethnicity were 32% lower than that in non-Asian patients. The exposures of irinotecan and SN-38 in patients with mild or moderate renal impairment were comparable to patients with normal renal function after adjusting for BSA. The exposures of irinotecan and SN-38 in patients with mild hepatic impairment (based on NCI score) were comparable to patients with normal hepatic function. There was insufficient data in patients with severe renal impairment (CLcr < 30 mL/min) or in patients with moderate and severe hepatic impairment to assess their effects on the exposures of irinotecan and SN-38. Increased AST/ALT had no effect on irinotecan clearance; however, increased bilirubin level was associated with lower SN‑38 clearance. SN-38 AUC was increased by 32% in patients with bilirubin level of 1.14 mg/dL (95 th of the overall population) compared with that of median bilirubin level of 0.44 mg/dL. No data are available in patients with bilirubin >2.8 mg/dL. Drug Interactions In a population pharmacokinetic analysis, the pharmacokinetics of total irinotecan and total SN-38 were not altered by the co-administration of fluorouracil/leucovorin. In Study MM‑398‑07‑02‑03 and NAPOLI-3, irinotecan AUC was decreased by 33% and SN-38 C max increased by 23% following co-administration with oxaliplatin. Following administration of irinotecan HCl, dexamethasone (moderate CYP3A4 inducer) does not alter the pharmacokinetics of irinotecan. In vitro studies indicate that irinotecan, SN-38 and another metabolite, aminopentane carboxylic acid (APC), do not inhibit cytochrome P-450 isozymes.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility No studies have been performed to assess the potential of irinotecan liposome for carcinogenicity, genotoxicity or impairment of fertility. Intravenous administration of irinotecan hydrochloride to rats once weekly for 13 weeks followed by a 91-week recovery period resulted in a significant linear trend between irinotecan HCl dosage and the incidence of combined uterine horn endometrial stromal polyps and endometrial stromal sarcomas. Irinotecan HCl was clastogenic both in vitro (chromosome aberrations in Chinese hamster ovary cells) and in vivo (micronucleus test in mice). Neither irinotecan nor its active metabolite, SN-38, was mutagenic in the in vitro Ames assay. Dedicated fertility studies have not been performed with irinotecan liposome injection. Atrophy of male and female reproductive organs was observed in dogs receiving irinotecan liposome injection every 3 weeks at doses equal to or greater than 15 mg/kg, (approximately 3 times the clinical exposure of irinotecan following administration to ONIVYDE dosed at 70 mg/m 2 ) for a total of 6 doses. No significant adverse effects on fertility and general reproductive performance were observed after intravenous administration of irinotecan HCl in doses of up to 6 mg/kg/day to rats; however, atrophy of male reproductive organs was observed after multiple daily irinotecan HCl doses both in rodents at 20 mg/kg (approximately 0.007 times the clinical irinotecan exposure following ONIVYDE administration at 70 mg/m 2 ) and in dogs at 0.4 mg/kg (0.0007 times the clinical exposure to irinotecan following administration of ONIVYDE).

14 CLINICAL STUDIES Pancreatic Adenocarcinoma In Combination with Oxaliplatin, Fluorouracil and Leucovorin for First-Line Treatment of Metastatic Pancreatic Adenocarcinoma The efficacy of ONIVYDE in combination with oxaliplatin, fluorouracil and leucovorin (NALIRIFOX) was evaluated in NAPOLI 3 (NCT04083235), a randomized, multicenter, open-label, active-controlled trial in 770 patients with metastatic pancreatic adenocarcinoma who had not previously received chemotherapy in the metastatic setting. Randomization was stratified by region, liver metastases and ECOG performance status. Patients were randomized (1:1) to receive one of the following treatment arm: NALIRIFOX: ONIVYDE 50 mg/m 2 as an intravenous infusion over 90 minutes, followed by oxaliplatin 60 mg/m 2 as an intravenous infusion over 120 minutes, followed by leucovorin 400 mg/m 2 intravenously over 30 minutes, followed by fluorouracil 2400 mg/m 2 intravenously over 46 hours, every 2 weeks. Gem+NabP: Nab-paclitaxel 125 mg/m 2 as an intravenous infusion over 35 minutes, followed by gemcitabine 1000 mg/m 2 intravenously over 30 minutes on days 1, 8 and 15 of each 28-day cycle. Patients homozygous for the UGT1A1*28 allele initiated ONIVYDE at the same dose (50 mg/m 2 ONIVYDE). Treatment continued until RECIST v1.1 defined disease progression or unacceptable toxicity. Tumor status assessments were conducted at baseline and every 8 weeks thereafter as assessed by the investigator according to RECIST v1.1. The main efficacy outcome measure was overall survival (OS). Additional efficacy measures were investigator-assessed progression-free survival (PFS) and objective response rate (ORR). Baseline demographic and patient characteristics were: median age of 65 years (range: 20-85); 50% age 65 or older; 56% male; 83% White, 4.9% Asian, 2.5% Black or African American, 0.4% multiple race, 0.3% American Indian or Alaska Native; 0.1% Native Hawaiian or other Pacific Islander, 1.7% other, 7% not reported; and 82% non-Hispanic, 10% Hispanic, 8% not reported. ECOG performance status was 0 or 1 in 44% and 56% of patients, respectively; 80% had liver metastases. NAPOLI 3 demonstrated a statistically significant improvement in OS and PFS for the NALIRIFOX arm over Gem+NabP arm as summarized in Table 8 and Figure 1.

Key eligibility criteria included Karnofsky Performance Status (KPS) ≥70, serum bilirubin within institution limits of normal, and albumin ≥3.0 g/dL. Patients were randomized to receive ONIVYDE plus fluorouracil/leucovorin (ONIVYDE/FU/LV), ONIVYDE, or fluorouracil/leucovorin (FU/LV). Randomization was stratified by ethnicity (White vs. East Asian vs. other), KPS (70-80 vs. 90-100), and baseline albumin level (≥ 4 g/dL vs. 3.0-3.9 g/dL). Patients randomized to ONIVYDE/FU/LV received ONIVYDE 70 mg/m 2 as an intravenous infusion over 90 minutes, followed by leucovorin 400 mg/m 2 intravenously over 30 minutes, followed by fluorouracil 2400 mg/m 2 intravenously over 46 hours, every 2 weeks. The ONIVYDE dose of 70 mg/m 2 is based on irinotecan free base (equivalent to 80 mg/m 2 of irinotecan as the hydrochloride trihydrate). Patients randomized to ONIVYDE as a single agent received ONIVYDE 100 mg/m 2 as an intravenous infusion over 90 minutes every 3 weeks. Patients randomized to FU/LV received leucovorin 200 mg/m 2 intravenously over 30 minutes, followed by fluorouracil 2000 mg/m 2 intravenously over 24 hours, administered on Days 1, 8, 15 and 22 of a 6-week cycle. Patients homozygous for the UGT1A1*28 allele initiated ONIVYDE at a reduced dose (50 mg/m 2 ONIVYDE, if given with FU/LV or 70 mg/m 2 ONIVYDE as a single agent). When ONIVYDE was withheld or discontinued for adverse reactions, FU was also withheld or discontinued. When the dose of ONIVYDE was reduced for adverse reactions, the dose of FU was reduced by 25%. Treatment continued until disease progression or unacceptable toxicity. The major efficacy outcome measure was overall survival (OS) with two pair-wise comparisons: ONIVYDE versus FU/LV and ONIVYDE/FU/LV versus FU/LV. Additional efficacy outcome measures were progression-free survival (PFS) and objective response rate (ORR). Tumor status assessments were conducted at baseline and every 6 weeks thereafter. The trial was initiated as a two-arm study and amended after initiation to include a third arm (ONIVYDE/FU/LV). The comparisons between the ONIVYDE/FU/LV and the FU/LV arms are limited to patients enrolled in the FU/LV arm after this protocol amendment. Four hundred seventeen patients were randomized to: ONIVYDE/FU/LV (N=117), ONIVYDE (N=151), or FU/LV (N=149). Baseline demographics and tumor characteristics for the 236 patients randomized to ONIVYDE/FU/LV or FU/LV (N=119) after the addition of the third arm to the study were a median age of 63 years (range 34-81 years) and with 41% ≥ 65 years of age; 58% were men; 63% were White, 30% were Asian, 3% were Black or African American, and 5% were other. Mean baseline albumin level was 3.97 g/dL, and baseline KPS was 90-100 in 53% of patients. Disease characteristics included liver metastasis (67%) and lung metastasis (31%). A total of 13% of patients received gemcitabine in the neoadjuvant/adjuvant setting only, 55% of patients had 1 prior line of therapy for metastatic disease, and 33% of patients had 2 or more prior lines of therapy for metastatic disease. All patients received prior gemcitabine (alone or in combination with another agent), 54% received prior gemcitabine in combination with another agent, and 13% received prior gemcitabine in combination with nab-paclitaxel. NAPOLI-1 demonstrated a statistically significant improvement in overall survival for the ONIVYDE/FU/LV arm over the FU/LV arm as summarized in Table 9 and Figure 2. There was no improvement in overall survival for the ONIVYDE arm over the FU/LV arm (hazard ratio=1.00, p-value=0.97 (two-sided log-rank test)).

8.5 Geriatric Use Of the 634 patients who received ONIVYDE as a single agent, in combination with FU and leucovorin or in combination with oxaliplatin, FU and leucovorin in NAPOLI-1 and NAPOLI 3, 49% were ≥ 65 years old and 10% were ≥ 75 years old. No overall differences in safety and effectiveness were observed between these patients and younger patients.

8.4 Pediatric Use Safety and effectiveness of ONIVYDE have not been established in pediatric patients.

8.1 Pregnancy Risk Summary Based on animal data with irinotecan HCl and the mechanism of action of ONIVYDE, ONIVYDE can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) ] . There are no available data in pregnant women. Embryotoxicity and teratogenicity were observed following treatment with irinotecan HCl, at doses resulting in irinotecan exposures lower than those achieved with ONIVYDE 70 mg/m 2 in humans, administered to pregnant rats and rabbits during organogenesis [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 2-4% and 15-20%, respectively. Data Animal Data No animal studies have been conducted to evaluate the effect of irinotecan liposome on reproduction and fetal development; however, studies have been conducted with irinotecan HCl. Irinotecan crosses the placenta of rats following intravenous administration. Intravenous administration of irinotecan at a dose of 6 mg/kg/day to rats and rabbits during the period of organogenesis resulted in increased post-implantation loss and decreased numbers of live fetuses. In separate studies in rats, this dose resulted in an irinotecan exposure of approximately 0.002 times the exposure of irinotecan based on area under the curve (AUC) in patients administered ONIVYDE at the 70 mg/m 2 dose. Administration of irinotecan HCl resulted in structural abnormalities and growth delays in rats at doses greater than 1.2 mg/kg/day (approximately 0.0002 times the clinical exposure to irinotecan in ONIVYDE based on AUC). Teratogenic effects included a variety of external, visceral, and skeletal abnormalities. Irinotecan HCl administered to rat dams for the period following organogenesis through weaning at doses of 6 mg/kg/day caused decreased learning ability and decreased female body weights in the offspring.

Irinotecan HCl administered to rat dams for the period following organogenesis through weaning at doses of 6 mg/kg/day caused decreased learning ability and decreased female body weights in the offspring. 8.2 Lactation Risk Summary There is no information regarding the presence of irinotecan liposome, irinotecan, or SN-38 (an active metabolite of irinotecan) in human milk, or the effects on the breastfed infant or on milk production. Irinotecan is present in rat milk [see Data ]. Because of the potential for serious adverse reactions in breastfed infants from ONIVYDE, advise a nursing woman not to breastfeed during treatment with ONIVYDE and for one month after the last dose. Data Radioactivity appeared in rat milk within 5 minutes of intravenous administration of radiolabeled irinotecan HCl and was concentrated up to 65-fold at 4 hours after administration relative to plasma concentrations. 8.3 Females and Males of Reproductive Potential Contraception Females ONIVYDE can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1) ]. Advise females of reproductive potential to use effective contraception during treatment with ONIVYDE and for seven months after the last dose. Males Because of the potential for genotoxicity, advise males with female partners of reproductive potential to use condoms during treatment with ONIVYDE and for four months after the last dose [see Nonclinical Toxicology (13.1) ]. 8.4 Pediatric Use Safety and effectiveness of ONIVYDE have not been established in pediatric patients. 8.5 Geriatric Use Of the 634 patients who received ONIVYDE as a single agent, in combination with FU and leucovorin or in combination with oxaliplatin, FU and leucovorin in NAPOLI-1 and NAPOLI 3, 49% were ≥ 65 years old and 10% were ≥ 75 years old. No overall differences in safety and effectiveness were observed between these patients and younger patients.
