5 Warnings and Precautions

5.1 Risk from Radiation Exposure

Additions and/or revisions underlined:

LUTATHERA contributes to a patient’s overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure is associated with an increased risk for cancer. These risks of radiation associated with the use of LUTATHERA are greater in pediatric patients than in adults [see Use in Specific Populations (8.4)].

6 Adverse Reactions

6.1 Clinical Trials Experience

Additions and/or revisions underlined:

Adult Population

Pediatric Population

NETTER-P

Safety data are available from 9 pediatric patients in NETTER-P (NCT04711135), an international, multi- center, single-arm, open-label trial of patients with somatostatin receptor-positive tumors, including 4 patients with GEP-NETs. Patients received LUTATHERA 7.4 GBq (200 mCi) administered every 8 weeks concurrently with the recommended amino acid solution. Adverse reactions observed in NETTER-P were similar to those observed in adults treated with LUTATHERA.

8 Use in Specific Populations

8.4 Pediatric Use

Additions and/or revisions underlined:

Somatostatin Receptor-Positive Gastroenteropancreatic Neuroendocrine Tumors

The safety and effectiveness of LUTATHERA have been established in pediatric patients 12 years and older with somatostatin receptor-positive gastroenteropancreatic neuroendocrine (GEP-NET). Use of LUTATHERA for this indication is supported by evidence from an adequate and well-controlled study of LUTATHERA in adults with additional safety, pharmacokinetic, and dosimetry data in pediatric patients aged 12 years and older with somatostatin receptor-positive tumors, including 4 pediatric patients with GEP-NETs [see Adverse Reactions (6.1), Clinical Pharmacology (12.3), and Clinical Studies (14)].

The risks of radiation exposure associated with LUTATHERA are greater in pediatric patients than in adult patients due to longer life expectancy. Continued follow-up is recommended for evaluation of long-term effects.

There was no clinically relevant difference in lutetium Lu 177 dotatate exposure in pediatric patients aged 13 to 16 years versus adult patients [see Clinical Pharmacology (12.3)].

The pharmacokinetic profile and safety of LUTATHERA in pediatric patients 12 years and older with baseline renal impairment have not been studied.

The safety and effectiveness of LUTATHERA have not been established in pediatric patients younger than 12 years old with somatostatin receptor-positive GEP-NET.

8.5 Geriatric Use

Additions and/or revisions underlined:

Of the 1325 patients treated with LUTATHERA in clinical trials, 438 patients (33%) were 65 years and older. No overall differences in safety or effectiveness were observed between older and younger patients.

17 PCI/PI/MG (Patient Counseling Information/Patient Information/Medication Guide)

5 Warnings and Precautions

5.1 Risk from Radiation Exposure

Additions and/or revisions underlined:

LUTATHERA contributes to a patient’s overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure is associated with an increased risk for cancer.

Radiation can be detected in the urine for up to 30 days following LUTATHERA administration. Minimize radiation exposure to patients, medical personnel, and household contacts during and after treatment with LUTATHERA consistent with institutional good radiation safety practices, patient management procedures, Nuclear Regulatory Commission patient-release guidance, and instructions to the patient for follow-up radiation protection at home [see Dosage and Administration (2.1), Clinical Pharmacology (12.3)].

5.2 Myelosuppression

Additions and/or revisions underlined:

In NETTER-1, myelosuppression occurred more frequently in patients receiving LUTATHERA with long- acting octreotide compared to patients receiving high-dose long-acting octreotide (all Grades/Grade 3 or 4): anemia (81%/0) versus (54%/1%); thrombocytopenia (53%/1%) versus (17%/0); and neutropenia (26%/3%) versus (11%/0). In NETTER-1, platelet nadir occurred at a median of 5.1 months following the first dose. Of the 59 patients who developed thrombocytopenia, 68% had platelet recovery to baseline or normal levels. The median time to platelet recovery was 2 months. Fifteen of the nineteen patients in whom platelet recovery was not documented had post-nadir platelet counts. Among these 15 patients, 5 improved to Grade 1, 9 to Grade 2, and 1 to Grade 3.

Monitor blood cell counts. Withhold dose, reduce dose, or permanently discontinue LUTATHERA based on the severity of myelosuppression [see Dosage and Administration (2.4)].

5.4 Renal Toxicity

Additions and/or revisions underlined:

In ERASMUS, 8 patients (< 1%) developed renal failure 3 to 36 months following LUTATHERA. Two of these patients had underlying renal impairment or risk factors for renal failure (e.g., diabetes or hypertension) and required dialysis.

Administer the recommended amino acid solution before, during and after LUTATHERA [see Dosage and Administration (2.3)] to decrease the reabsorption of lutetium Lu 177 dotatate through the proximal tubules and decrease the radiation dose to the kidneys. Advise patients to hydrate and to urinate frequently before, on the day of, and the day after administration of LUTATHERA

Monitor serum creatinine and calculated creatinine clearance. Withhold dose, reduce dose, or permanently discontinue LUTATHERA based on the severity of renal toxicity [see Dosage and Administration (2.4)].

Patients with baseline renal impairment may be at increased risk of toxicity due to increased radiation exposure [see Use in Specific Populations (8.6)].

5.5 Hepatoxicity

Additions and/or revisions underlined:

In ERASMUS, 2 patients (< 1%) were reported to have hepatic tumor hemorrhage, edema, or necrosis, with one patient experiencing intrahepatic congestion and cholestasis. Patients with hepatic metastasis may be at increased risk of hepatotoxicity due to radiation exposure.

Monitor transaminases, bilirubin, serum albumin and international normalized ratio (INR) during treatment. Withhold dose, reduce dose, or permanently discontinue LUTATHERA based on the severity of hepatotoxicity [see Dosage and Administration (2.4)].

5.8 Embryo-Fetal Toxicity

Additions and/or revisions underlined:

Based on its mechanism of action, LUTATHERA can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. There are no available data on LUTATHERA use in pregnant women. No animal studies using lutetium Lu 177 dotatate have been conducted to evaluate its effect on female reproduction and embryo-fetal development; however, radioactive emissions, including those from LUTATHERA, can cause fetal harm.

Verify pregnancy status of females of reproductive potential prior to initiating LUTATHERA [see Dosage and Administration (2.1)].

Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with LUTATHERA and for 7 months after the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with LUTATHERA and for 4 months after the last dose [see Use in Specific Populations (8.1, 8.3)].

7 Drug Interactions

7.2 Glucocorticoids

Subsection title revised; Additions and/or revisions underlined:

Glucocorticoids can induce down-regulation of subtype 2 somatostatin receptors (SSTR2). Avoid repeated administration of high doses of glucocorticoids during treatment with LUTATHERA.

8 Use in Specific Populations

8.1 Pregnancy

Additions and/or revisions underlined:

Risk Summary

Based on its mechanism of action, LUTATHERA can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. There are no available data on LUTATHERA use in pregnant women. No animal studies using lutetium Lu 177 dotatate have been conducted to evaluate its effect on female reproduction and embryo-fetal development; however, radioactive emissions, including those from LUTATHERA, can cause fetal harm. 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.

8.2 Lactation

Additions and/or revisions underlined:

Risk Summary

There are no data on the presence of lutetium Lu 177 dotatate in human milk, or its effects on the breastfed child or milk production. No lactation studies in animals were conducted. Because of the potential risk for serious adverse reactions in breastfed children, advise women not to breastfeed during treatment with LUTATHERA and for 2.5 months after the last dose.

8.3 Females and Males of Reproductive Potential

Additions and/or revisions underlined:

Based on mechanism of action, LUTATHERA can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)].

Pregnancy Testing

Contraception

Females

Advise females of reproductive potential to use effective contraception during treatment with LUTATHERA and for 7 months after the last dose.

Males

Advise males with female partners of reproductive potential to use effective contraception during treatment with LUTATHERA and for 4 months after the last dose [see Clinical Pharmacology (12.1), Nonclinical Toxicology (13.1)].

Infertility

The recommended cumulative dose of 29.6 GBq of LUTATHERA results in a radiation absorbed dose to the testes and ovaries within the range where temporary or permanent infertility can be expected following external beam radiotherapy [see Dosage and Administration (2.6)].

8.6 Renal Impairment

Additions and/or revisions underlined:

No dose adjustment is recommended for patients with baseline mild to moderate (creatinine clearance 30 to 89 mL/min by Cockcroft-Gault formula) renal impairment. However, patients with baseline mild or moderate renal impairment may be at greater risk of toxicity, including renal toxicity, due to increased radiation exposure.

Perform more frequent assessments of renal function in patients with baseline mild to moderate impairment. The pharmacokinetic profile and safety of LUTATHERA in patients with baseline severe renal impairment (creatinine clearance < 30 mL/min by Cockcroft-Gault formula) or end-stage renal disease have not been studied [see Warnings and Precautions (5.4)].

8.7 Hepatic Impairment

Additions and/or revisions underlined:

No dose adjustment is recommended for patients with baseline mild or moderate hepatic impairment. The pharmacokinetic profile and safety of LUTATHERA in patients with baseline severe hepatic impairment (total bilirubin > 3 times upper limit of normal, regardless of AST level) have not been studied.
