1 INDICATIONS AND USAGE
TRYNGOLZA ®is indicated as an adjunct to diet:
- To reduce triglycerides (TG) in adults with familial chylomicronemia syndrome (FCS).
- To reduce TG and the risk of acute pancreatitis in adults with severe hypertriglyceridemia (sHTG: TG greater than or equal to 500 mg/dL).
2 DOSAGE AND ADMINISTRATION
2.1 Recommended Dosage
In adults with FCS:
- The recommended dosage of TRYNGOLZA is 80 mg injected subcutaneously once monthly
[see
Dosage and Administration (2.2) ] .
In adults with sHTG:
- The recommended dosage of TRYNGOLZA is 50 mg injected subcutaneously once monthly
[see
Dosage and Administration (2.2) ]. - Assess TG when clinically appropriate. The TG-lowering effect of TRYNGOLZA may be measured within 3 months after initiation.
- For patients who tolerate the 50 mg dosage and additional TG reduction is clinically indicated, the dosage may be increased to 80 mg injected subcutaneously once monthly.
2.2 Administration Instructions
- Prior to initiation, train patients and/or caregivers on proper preparation and administration of TRYNGOLZA
[see
Instructions for Use ] . - Advise patients to maintain a low-fat diet in conjunction with TRYNGOLZA. Instruct patients with FCS to consume 20 g or less of fat per day.
- Remove the single-dose autoinjector from the refrigerator and let the autoinjector come to room temperature 30 minutes prior to the injection. Do not use other warming methods.
- Inspect TRYNGOLZA visually for particulate matter prior to administration. The solution should be a clear and colorless to yellow liquid. Do not use if cloudiness, particulate matter, or discoloration is observed prior to administration.
- Inject TRYNGOLZA subcutaneously into the abdomen or front of the thigh. The back of the upper arm can also be used as an injection site if a healthcare provider or caregiver administers the injection.
- Administer TRYNGOLZA as soon as possible after a missed dose. Resume dosing at monthly intervals from the date of the most recently administered dose.
3 DOSAGE FORMS AND STRENGTHS
Injection:
- 50 mg/0.8 mL of olezarsen as a clear, colorless to yellow solution in a single-dose autoinjector
- 80 mg/0.8 mL of olezarsen as a clear, colorless to yellow solution in a single-dose autoinjector
4 CONTRAINDICATIONS
TRYNGOLZA is contraindicated in patients with a history of serious hypersensitivity to olezarsen or any of the excipients in TRYNGOLZA. Hypersensitivity reactions, including symptoms of bronchospasm, diffuse erythema, facial swelling, urticaria, chills, and myalgias, requiring medical treatment have occurred
[see
5 WARNINGS AND PRECAUTIONS
5.1 Hypersensitivity Reactions
Hypersensitivity reactions (including symptoms of bronchospasm, diffuse erythema, facial swelling, urticaria, chills, and myalgias) have been reported in patients treated with TRYNGOLZA
[see
5.2 Liver Enzyme Abnormalities
TRYNGOLZA can cause increases in liver enzymes and hepatic fat in adults
[see
Increases in liver enzymes were more frequently reported with the 80 mg dose as compared to the 50 mg dose. In patients with sHTG, increases in liver enzymes greater than or equal to three times the upper limit of normal were reported more frequently with TRYNGOLZA 80 mg (7%) compared to TRYNGOLZA 50 mg (3%) and placebo (3%).
Consider liver enzyme testing before TRYNGOLZA initiation or an increase in dosage and when clinically indicated thereafter. If persistent elevations in liver enzymes occur (such as three times the upper limit of normal or greater), consider dose interruption and/or dose reduction. If serious hepatic injury with clinical symptoms and/or hyperbilirubinemia or jaundice occurs, promptly discontinue TRYNGOLZA.
6 ADVERSE REACTIONS

[see
Warnings and Precautions (5.2) ]
6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of TRYNGOLZA cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Clinical Trial in Patients with FCS
The safety of TRYNGOLZA was evaluated in 66 patients with FCS enrolled in Trial 1 (NCT #04568434)
[see
Adverse reactions led to discontinuation of treatment in 7% of TRYNGOLZA-treated patients and 0% of placebo-treated patients. The most common reason for TRYNGOLZA treatment discontinuation was hypersensitivity reactions. Adverse reactions (>5% of patients treated with TRYNGOLZA and at >3% higher frequency than placebo) are presented in Table 1.

Clinical Trials in Patients with sHTG
The safety of TRYNGOLZA was evaluated in two randomized, double-blind, placebo-controlled trials [Trial 2 (NCT #05079919) and Trial 3 (NCT #05552326)] that included a total of 1,061 adult patients with sHTG
[see
Adverse reactions led to discontinuation of treatment in 5% of TRYNGOLZA-treated patients and 2% of placebo-treated patients. The most common adverse reaction for TRYNGOLZA treatment discontinuation was injection site reactions.
Adverse reactions (in patients treated with TRYNGOLZA at ≥2% higher frequency than placebo) are presented in Table 2.

Laboratory Tests
Decrease in Platelet Count: TRYNGOLZA can cause reductions in platelet count. Across all trials (Trials 1, 2, and 3), mean decreases from baseline through Week 53 ranging from 6% (50 mg, Trial 2 and Trial 3) to 10% (80 mg across all trials), were observed in TRYNGOLZA-treated patients, whereas placebo-treated patients showed an increase of 22% in Trial 1 or no change in Trial 2 and Trial 3. The proportion of patients experiencing a bleeding adverse event was similar between the TRYNGOLZA and placebo groups. There were no major bleeding events associated with low platelet counts.
Increase in Glucose: Increases in average values in fasting glucose (≤17 mg/dL) and HbA1c (<0.2 percentage points) were observed over time with TRYNGOLZA treatment in the FCS population in Trial 1. The incidence of hyperglycemia (defined as adverse events, new antidiabetic medication, or laboratory values) was higher in patients with FCS treated with TRYNGOLZA without a medical history of diabetes at baseline (52%) compared to placebo-treated patients (35%).
In Trials 2 and 3, increases in average values in fasting glucose (≤9 mg/dL) and HbA1c (<0.3 percentage points) were observed over time in the sHTG population treated with TRYNGOLZA. These increases were more pronounced in patients with a history of diabetes at baseline; however, increases in fasting glucose and HbA1c were also observed more frequently with TRYNGOLZA compared to placebo in patients without a history of diabetes at baseline.
Increase in Liver Enzymes: Mean liver enzyme values increased from baseline with TRYNGOLZA treatment but remained within the normal range. These increases occurred within the first 6 months of treatment and stabilized. However, when evaluating any liver enzyme increase in patients with sHTG, increases in liver enzymes greater than or equal to three times the upper limit of normal were reported more frequently with TRYNGOLZA 80 mg (7%) compared to TRYNGOLZA 50 mg (3%) and placebo (3%). Liver enzymes returned toward baseline with discontinuation of TRYNGOLZA.
Increase in Hepatic Fat Fraction: Hepatic fat fraction (HFF) was assessed in patients with sHTG in a substudy within Trial 2 and Trial 3. Mean HFFs were elevated at baseline (17% TRYNGOLZA 50 mg, 14% TRYNGOLZA 80 mg, 14% placebo). Dose-dependent changes in HFF at 12 months of treatment were a mean increase of 2 percentage points in the TRYNGOLZA 50 mg group and 4 percentage points in the TRYNGOLZA 80 mg group versus 0 percentage points in the placebo group. The clinical meaningfulness of these findings remains uncertain.
Increase in LDL-cholesterol: In all trials, increases were observed in LDL-C in TRYNGOLZA-treated patients compared with placebo. These increases were accompanied by decreases in non–high-density lipoprotein cholesterol (non-HDL-C). Among patients with FCS, total apolipoprotein B (apoB) increased, whereas among patients with sHTG, apoB decreased

8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Risk Summary
There are no available data on TRYNGOLZA use in pregnant women to inform drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Patients with FCS or sHTG are at risk for pancreatitis during pregnancy because of increased TG levels
(see
In animal reproduction studies conducted with the unconjugated antisense oligonucleotide (lacking N-acetylgalactosamine [GalNAc]) in rabbits and mice, no adverse effects on development or pregnancy were observed at doses 21 times or 20 times, respectively, the maximum recommended clinical dose.
The background risk of major birth defects and miscarriage for the indicated populations are unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. 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.
Clinical Considerations
Disease-Associated Maternal and/or Embryo-Fetal Risk
Triglyceride levels increase during the third trimester of pregnancy. In patients with underlying defects in triglyceride metabolism, severe gestational hypertriglyceridemia may occur, increasing the risk of acute pancreatitis during pregnancy.
Data
Animal Data
Olezarsen was not evaluated for potential effects on embryofetal development (EFD). However, effects of the administration of the unconjugated antisense oligonucleotide (ASO), which shares the same nucleotide sequence but lacks the (GalNAc) moiety
[see
In a combined fertility and embryo-fetal development study in mice, the unconjugated ASO was administered to male and female mice by subcutaneous injection at doses of 10.5, 35, and 87.5 mg/kg/week prior to mating and through to the completion of organogenesis (gestation day 15). No adverse developmental outcomes occurred at doses up to 87.5 mg/kg/week (approximately 21-times the monthly maximum recommended human dose (MRHD) based on a body surface area (BSA) comparison of the unconjugated ASO).
In an embryo-fetal development study in pregnant rabbits, the unconjugated ASO was administered by subcutaneous injection at doses of 10.5, 21, and 52.5 mg/kg/week during the period of organogenesis (gestation days 6 to 18). No adverse developmental effects were observed at doses up to 21 mg/kg/week (approximately 20-times the monthly MRHD based on a BSA comparison of the unconjugated ASO).
In a pre-/postnatal toxicity study in mice, the unconjugated ASO was administered at 10.5, 35, or 87.5 mg/kg/week during the period of organogenesis and continuing until weaning (gestation day 6 through lactation day 21). Offspring body weights at 87.5 mg/kg/week (21-times the monthly MRHD based on BSA) were lower throughout their lives and were associated with slight delays in the attainment of morphological and developmental landmarks. No adverse effects on offspring were observed at 35 mg/kg/week (approximately 9-times the monthly MRHD based on a BSA comparison of the unconjugated ASO).
8.2 Lactation
Risk Summary
There are no data on the presence of olezarsen in either human or animal milk, the effects on the breastfed infant, or the effects on milk production. However, the unconjugated antisense ASO, which shares the same nucleotide sequence but lacks GalNAc, was present in the milk of lactating mice at low levels. When a drug is present in animal milk, it is likely that the drug will be present in human milk. Oligonucleotide-based products typically have poor oral bioavailability; therefore, it is considered unlikely that low levels present in milk will lead to clinically relevant levels in breastfed infants. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for TRYNGOLZA and any potential adverse effects on the breastfed infant from TRYNGOLZA or from the underlying maternal condition.
8.4 Pediatric Use
The safety and effectiveness of TRYNGOLZA in pediatric patients have not been established.
8.5 Geriatric Use
No dose adjustment is recommended in patients aged 65 years and older
[see
8.6 Renal Impairment
No dose adjustment is necessary in patients with mild to moderate renal impairment [estimated glomerular filtration rate (eGFR) ≥30 to <90 mL/min]
[see
8.7 Hepatic Impairment
No dose adjustment is recommended in patients with mild or moderate hepatic impairment
[see
11 DESCRIPTION
Olezarsen is an ASO directed inhibitor of apolipoprotein C-III (apoC-III) mRNA, conjugated to a ligand containing three GalNAc residues to enable delivery of the ASO to hepatocytes.
TRYNGOLZA contains olezarsen sodium as the active ingredient. Olezarsen sodium is a white to yellow solid and it is freely soluble in water and in phosphate buffer. The molecular formula of olezarsen sodium is C 296H 419N 71O 154P 20S 19Na 20 and the molecular weight is 9124.48 daltons. The chemical name of olezarsen sodium is DNA, d(P-thio) ([2'- O-(2-methoxyethyl)] rA-[2'- O-(2-methoxyethyl)] rG-[2'- O-(2-methoxyethyl)] m5rC-[2'- O-(2-methoxyethyl)] m5rU-[2'- O-(2-methoxyethyl)] m5rU-m5C-T-T-G-T-m5C-m5C-A-G-m5C-[2'- O-(2-methoxyethyl)] m5rU-[2'- O-(2-methoxyethyl)] m5rU-[2'- O-(2-methoxyethyl)] m5rU-[2'- O-(2-methoxyethyl)] rA-[2'- O-(2-methoxyethyl)]m5rU), 5'-[26-[[2-(acetylamino)-2-deoxy-β-D-galactopyranosyl]oxy]-14,14-bis[[3-[[6-[[2-(acetylamino)-2-deoxy-β-D-galactopyranosyl]oxy]hexyl]amino]-3-oxopropoxy]methyl]-8,12,19-trioxo-16-oxa-7,13,20-triazahexacos-1-yl hydrogen phosphate], sodium salt (1:20).
The structure of olezarsen sodium is presented below:
TRYNGOLZA is a sterile, preservative-free solution for subcutaneous injection. Each single-dose autoinjector contains 50 mg olezarsen (equivalent to 53 mg of olezarsen sodium) in 0.8 mL of solution or 80 mg olezarsen (equivalent to 84 mg of olezarsen sodium) in 0.8 mL of solution. The solution also contains the following inactive ingredients: disodium hydrogen phosphate, sodium chloride, sodium dihydrogen phosphate to maintain pH and provide tonicity, and water for injection. The solution may include hydrochloric acid and/or sodium hydroxide for pH adjustment between 6.9 to 7.9. Each 50 mg dose of TRYNGOLZA injection contains 4 mg of phosphorous and 4 mg of sodium. Each 80 mg dose of TRYNGOLZA injection contains 6 mg of phosphorous and 5 mg of sodium.
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Olezarsen is an ASO-GalNAc 3 conjugate that binds to apoC-III mRNA leading to mRNA degradation and resulting in a reduction of serum apoC-III protein. Reduction of apoC-III protein leads to increased clearance of plasma TG and very low-density lipoprotein (VLDL).
12.2 Pharmacodynamics
Fasting apoC-III
Olezarsen decreased fasting apoC-III following administration of TRYNGOLZA 80 mg dosage every 4 weeks to patients with FCS
[see
Cardiac Electrophysiology
At a dose 1.5-times the maximum approved recommended dosage, TRYNGOLZA does not prolong the QT interval to any clinically relevant extent.
12.3 Pharmacokinetics
Olezarsen steady-state geometric mean (geometric % coefficient of variation [geometric %CV]) maximum concentrations (C max) is 659 (88.5%) ng/mL and area under the curve (AUC τ) is 8,030 (83.7%) ng*h/mL at the approved recommended dosage in patients with FCS (80 mg per month); 157 (90%) ng/mL and 3,470 (104%) ng*h/mL, respectively, at 50 mg once monthly in patients with sHTG, and 251 (90%) ng/mL and 5,550 (104%) ng*h/mL, respectively, at 80 mg once monthly in patients with sHTG. Olezarsen C maxand AUC increase dose-proportionally following single subcutaneous doses ranging from 10 to 120 mg (i.e., 0.13- to 1.5-times the approved recommended dose) in healthy volunteers. No olezarsen accumulation occurs with repeat dosing.
Absorption
Olezarsen time to C max (T max) is approximately 2 hours following subcutaneous administration.
Distribution
The population estimates for the apparent central volume of distribution is 96.1 L and 127 L and the apparent peripheral volume of distribution is 3,920 L and 6,660 L, for patients with FCS and sHTG, respectively, for olezarsen. Olezarsen is greater than 99% bound to plasma proteins, in vitro.
Olezarsen distributes primarily to the liver and kidney after subcutaneous dosing.
Elimination
Olezarsen terminal elimination half-life is approximately 4 weeks.
Metabolism
Olezarsen is metabolized by endo- and exonucleases to short oligonucleotide fragments of varying sizes within the liver.
Excretion
Less than 1% of olezarsen administered dose is eliminated unchanged in urine within 24 hours.
Specific Populations
No clinically significant differences in the pharmacokinetics of olezarsen were observed based on age (<65 to ≥75 years), body weight, sex, race (White, Black or African American, Asian, Japanese, American Indian or Alaska Native, Native Hawaiian or Pacific Islander), mild-to-moderate renal impairment (eGFR ≥30 to <90 mL/min) [CKD-EPI], mild hepatic impairment (total bilirubin ≤ULN and AST >ULN, or total bilirubin >1 to 1.5 x ULN and any AST, National Cancer Institute Organ Dysfunction Working Group criteria), or moderate hepatic impairment (Child-Pugh Class B score of 7 to 9). The effect of severe renal impairment (eGFR<30 mL/min), end-stage renal disease, or severe hepatic impairment (total bilirubin >3x ULN with any AST) on olezarsen pharmacokinetics is unknown.
Drug Interaction Studies
In Vitro Studies
CYP450 Enzymes:
Olezarsen is not an inhibitor or inducer of CYP450 enzymes.
Transporter Systems: Olezarsen is not a substrate or inhibitor of OAT1, OAT3, OCT1, OCT2, OATP1B1, OATP1B3, MATE1, MATE2-K, BCRP, P-gp, and BSEP.
Protein Binding: Olezarsen does not displace warfarin and ibuprofen from plasma protein binding sites.
12.6 Immunogenicity
The observed incidence of anti-drug antibodies (ADAs) is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of ADAs in the study described below with the incidence of anti-drug antibodies in other studies, including those of olezarsen.
In Trial 1, among patients with FCS treated with TRYNGOLZA, 18 of 43 patients (42%) developed treatment-emergent anti-drug antibodies (ADAs) through 53 weeks of treatment. In Trials 2 and 3, among patients with severe hypertriglyceridemia (sHTG) treated with TRYNGOLZA, 218 of 409 patients (53%) and 147 of 296 patients (50%), respectively, developed treatment-emergent ADAs through 53 weeks of treatment. The presence of ADAs did not affect olezarsen plasma C max, but increased C trough. These ADA-associated pharmacokinetic changes were not identified to be clinically significant. There was no identified clinically significant effect of ADAs on pharmacodynamics, safety, or efficacy of TRYNGOLZA in patients with FCS or sHTG.
13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Carcinogenesis
No long-term carcinogenicity studies were conducted with olezarsen in animals. However, the unconjugated antisense oligonucleotide (ASO) lacking GalNAc was administered weekly in mice and rats at subcutaneous doses of 0, 6, 25 and 40 mg/kg/week (along with a mouse-specific surrogate ASO at 25 mg/kg/week) and 0, 0.2, 1 and 5 mg/kg/week, respectively, for 2 years. In male mice, there were statistically significant increases in the incidences of hepatocellular adenomas and carcinomas at ≥25 mg/kg/week and hemangiomas and hemangiosarcomas at all doses. In female mice, there were statistically significant increases in the incidences of histiocytic sarcomas at all doses (including the mouse-specific surrogate) and pituitary gland adenomas at 25 mg/kg/week. In rats, the incidence of malignant fibrous histiocytoma at the injection site was increased in both sexes at doses ≥1 mg/kg/week. These tumors are considered a response to chronic tissue irritation and inflammation caused by repeated subcutaneous injection. The clinical significance of these findings is uncertain.
Mutagenesis
Olezarsen was negative for genotoxicity in vitro(bacterial reverse mutation assay and chromosome aberration assay in Chinese hamster lung cells) and in vivo(mouse bone marrow micronucleus assay).
Impairment of Fertility
Olezarsen was administered at doses of 0, 5, 10, or 20 mg/kg given every other week to male and female mice prior to mating, followed by every other day dosing after mating and until gestation day 6 in females. There was no effect on fertility in mice administered olezarsen at doses up to 20 mg/kg (approximately 2-times the monthly maximum recommended human dose based on body surface area).
14 CLINICAL STUDIES
14.1 Adult Patients with Familial Chylomicronemia Syndrome
The efficacy of TRYNGOLZA was demonstrated in a randomized, placebo-controlled, double-blind clinical trial in adult patients with genetically identified FCS and fasting TG levels ≥880 mg/dL (Trial 1;
Patient demographic and baseline characteristics were generally similar across the treatment groups
[see
The primary endpoint was percent change in fasting TG from baseline to Month 6 (average of Weeks 23, 25, and 27) compared to placebo. The difference between TRYNGOLZA 80 mg group and the placebo group in percent change in fasting TG from baseline to Month 6 was -43% (95% CI: -74%, -11%; p=0.0084). For additional results see Table 3.

| Abbreviations: apoB = apolipoprotein B; non-HDL-C = non high-density lipoprotein cholesterol; LDL-C = low-density lipoprotein cholesterol.
Note: Analyses results were based on an analysis of covariance model with treatment, the two randomization stratification factors, prior history of pancreatitis within 10 years prior to Screening (yes vs. no), previous treatment with the unconjugated ASO (yes vs. no) as the fixed effects and log-transformed Baseline value as a covariate. Missing data was imputed using placebo washout imputation. The 95% CIs of treatment differences were calculated using a robust variance estimator. For TG and non-HDL, a test of residual normality did not indicate significant departure from normal distribution. |

Patient demographic and baseline characteristics across pooled Trial 2 and Trial 3 were generally similar across treatment groups
[see
The primary endpoint in Trial 2 and Trial 3 was the percent change in fasting TG from baseline to Month 6 (average of Weeks 25 and 27) compared with placebo. Table 4 summarizes the mean percent change from baseline in TG at Month 6 and other key lipid parameters (non-HDL-C, LDL-C, total ApoB, and ApoB-48) for TRYNGOLZA 50 mg and 80 mg compared with placebo in Trial 2 and Trial 3. In both Trial 2 and Trial 3, TRYNGOLZA demonstrated statistically significant decreases in fasting TG at Month 6 and Month 12. In Trial 2, the placebo-corrected difference in percent change in fasting TG from baseline to Month 6 was -63% (95% CI: -72%, -54%; p <0.0001) for TRYNGOLZA 50 mg and -72% (95% CI: -81%, -63%; p <0.0001) for TRYNGOLZA 80 mg. In Trial 3, the placebo-corrected difference in percent change in fasting TG from baseline to Month 6 was -49% (95% CI: -60%, -39%; p <0.0001) for TRYNGOLZA 50 mg and -55% (95% CI: -65%, -44%; p <0.0001) for TRYNGOLZA 80 mg.

In Trial 2 (Figure 3) and Trial 3 (Figure 4), TRYNGOLZA demonstrated a consistent TG-lowering effect during the 12-month treatment period, as shown by reductions in mean percent change from baseline over time.
Figure 3. Percent Change in Fasting TG (mg/dL) Over Time in Patients with sHTG (Trial 2)
Pancreatitis events were assessed as a secondary endpoint in an integrated analysis of Trials 2 and 3. Events were adjudicated by a blinded, independent committee according to the Revised Atlanta Diagnostic Criteria, and event rates were compared between TRYNGOLZA groups and pooled placebo over 53 weeks. In the integrated analysis, TRYNGOLZA 50 mg and 80 mg reduced the adjudicated acute pancreatitis event rate by 91% (Rate Ratio: 0.09; 95% CI: 0.02, 0.42) and 76% (RR: 0.24; 95% CI: 0.08, 0.69) relative to placebo, respectively, with the pooled TRYNGOLZA group demonstrating an 85% reduction (RR: 0.15; 95% CI: 0.05, 0.40).
The overall treatment effect was predominantly observed in the prespecified high-risk subgroup of subjects with baseline fasting TG ≥880 mg/dL and a prior history of pancreatitis, which accounted for 25 of 29 total adjudicated acute pancreatitis events (86%). In this subgroup (N=141), TRYNGOLZA 50 mg and 80 mg reduced the acute pancreatitis event rate by 89% (RR: 0.11; 95% CI: 0.02, 0.51) and 75% (RR: 0.25; 95% CI: 0.08, 0.82) relative to placebo, respectively, with the pooled TRYNGOLZA group demonstrating an 83% reduction (RR: 0.17; 95% CI: 0.06, 0.47). For additional results, see Table 5.
