Dosing and Administration

PREMEDICATION AND CONCOMITANT MEDICATIONS

Premedication and Concomitant Medications

Somatostatin Analogs¹
4 weeks prior	Before initiating LUTATHERA treatment, discontinue long-acting SSAs (eg, long-acting octreotide) at least 4 weeks prior to initiating LUTATHERA. Administer short-acting octreotide as needed; discontinue at least 24 hours prior to initiating LUTATHERA.
4 to 24 hours after	During treatment with LUTATHERA, administer long-acting octreotide 30 mg IM between 4 to 24 hours after each dose of LUTATHERA. Do not administer long-acting octreotide within 4 weeks prior to each subsequent dose of LUTATHERA. Short-acting octreotide may be given for symptomatic management during treatment with LUTATHERA but must be withheld at least 24 hours before each dose of LUTATHERA.
4 weeks after	Following treatment with LUTATHERA, continue long-acting octreotide 30 mg IM every 4 weeks after completing LUTATHERA until disease progression or for 18 months following treatment initiation at the discretion of the physician.

Antiemetics and Amino Acids

Patients treated with LUTATHERA in the NETTER-1 trial received an amino acid solution for renal protection.^1,2

Premedication with antiemetics should be administered prior to the start of the amino acid solution infusion¹
Initiate an IV infusion of a sterile amino acid solution containing L-lysine and L-arginine 30 minutes before the start of the LUTATHERA infusion. Use a 3-way valve to administer the amino acid solution using the same venous access as LUTATHERA or administer the amino acid solution through a separate venous access in the patient’s other arm. Continue the infusion during and for at least 3 hours after completion of the infusion of LUTATHERA¹
– Do not decrease the dose of the amino acid solution if a reduced dose of LUTATHERA is administered¹
For more information about the amino acid solution, please refer to the full Prescribing Information for LUTATHERA

Hypersensitivity Prophylaxis

Premedicate patients who have had prior grade 1/2 hypersensitivity reactions to LUTATHERA. Do not re-challenge patients who experience grade 3/4 hypersensitivity reactions to LUTATHERA.¹

Treatment Regimen

Before initiating LUTATHERA: Discontinue long-acting SSAs (eg, long-acting octreotide) for at least 4 weeks prior to initiating LUTATHERA. Administer short-acting octreotide as needed; discontinue at least 24 hours prior to initiating LUTATHERA.¹

During LUTATHERA treatment: Administer long-acting octreotide 30 mg IM between 4 to 24 hours after each LUTATHERA dose. Do not administer long-acting octreotide within 4 weeks prior to each subsequent LUTATHERA dose. Short-acting octreotide may be given for symptomatic management during LUTATHERA treatment but must be withheld for at least 24 hours before each LUTATHERA dose.¹

Following treatment with LUTATHERA, continue long-acting octreotide 30 mg IM every 4 weeks after completing LUTATHERA until disease progression or for 18 months following treatment initiation at the discretion of the physician.¹

Recommended treatment regimen for LUTATHERA® (lutetium Lu 177 dotatate)

Long-acting SSAs should be discontinued at least 4 weeks prior to initiating LUTATHERA.¹

Short-acting octreotide may be given for symptomatic management during treatment with LUTATHERA but must be withheld for at least 24 hours before each dose of LUTATHERA.¹

LUTATHERA dosage should be modified based on hematologic, renal, hepatic, hypersensitivity, or other adverse reactions (see full Prescribing Information).¹

For reduced dose administration instructions, refer to section 2.5 (Preparation and Administration) of the full Prescribing Information

^aAdminister long-acting octreotide 30 mg IM between 4 to 24 hours after each dose of LUTATHERA. Do not administer long-acting octreotide within 4 weeks prior to each subsequent dose of LUTATHERA.¹

– The interval between infusions may be extended up to 16 weeks in the case of a dose modification due to an adverse reaction.¹ Permanently discontinue LUTATHERA in patients who experience grade 3/4 hypersensitivity reactions. Please see the Prescribing Information for additional information on dose modifications.

^bContinue long-acting octreotide 30 mg IM every 4 weeks after completing LUTATHERA until disease progression or for 18 months following treatment initiation at the discretion of the physician.¹

Infusion Schedule and Procedures

1. Pretreatment Antiemetic:

Premedication with antiemetics should be administered prior to the start of the amino acid solution infusion¹

2. Concomitant Amino Acid Infusion¹

Initiate an IV infusion of a sterile amino acid solution containing L-lysine and L-arginine 30 minutes before the start of the LUTATHERA infusion. Use a 3-way valve to administer the amino acid solution using the same venous access as LUTATHERA or administer the amino acid solution through a separate venous access in the patient’s other arm. Continue the infusion during and for at least 3 hours after the completion of the infusion of LUTATHERA¹
– Do not decrease the dose of the amino acid solution if a reduced dose of LUTATHERA is administered¹

Amino Acid Solution
Characteristic¹	Specification
L-lysine HCI	Between 18 and 25 g^c
L-arginine HCI	Between 18 and 25 g^d
Volume	1 to 2 L
Osmolality	<1200 mOsmol/kg

^cEquivalent to 14.4 g to 20 g L-lysine.¹
^dEquivalent to 14.9 g to 20.7 g L-arginine.¹

3. Hypersensitivity Prophylaxis¹

Premedicate patients who have had prior grade 1/2 hypersensitivity reactions to LUTATHERA. Do not rechallenge patients who experience grade 3/4 hypersensitivity reactions to LUTATHERA

4. Administration of LUTATHERA Using the Gravity Method

7.4 GBq (200 mCi) of LUTATHERA is administered IV over 30 to 40 minutes with the gravity method¹
– Do not inject LUTATHERA directly into any other IV solution
The gravity method, peristaltic pump method, or the syringe pump method may be used for the administration of the recommended dosage. Use the peristaltic pump or syringe pump method when administering a reduced dose of LUTATHERA following a dosage modification for an adverse reaction. When using the gravity method for a reduced dose, adjust the LUTATHERA dose before the administration to avoid the delivery of an incorrect volume of LUTATHERA¹
– For instructions on how to use the gravity method, peristaltic pump method, or the syringe pump method to administer LUTATHERA, please refer to the full Prescribing Information

Patient Management

Patient Management Before and During Treatment With LUTATHERA

Prescribing Information Directions

Advise patients of the need for periodic laboratory tests to monitor for adverse events¹
Advise patients to hydrate and to urinate frequently before, on the day of, and the day after administration of LUTATHERA¹
Monitor patients for flushing, diarrhea, hypotension, bronchoconstriction, or other signs and symptoms of tumor-related hormonal release¹:
– Administer IV somatostatin analogs
– Fluids
– Corticosteroids
– Electrolytes as indicated
Pregnancy status must be verified in women of childbearing potential prior to initiating LUTATHERA¹
Patients should not breastfeed during treatment with LUTATHERA and for 2.5 months after the last infusion of LUTATHERA¹

Monitor patients closely for signs and symptoms of hypersensitivity reactions, including anaphylaxis, during and following LUTATHERA administration for a minimum of 2 hours in a setting in which cardiopulmonary resuscitation medication and equipment are available. Discontinue the infusion upon the first observation of any signs or symptoms consistent with a severe hypersensitivity reaction and initiate appropriate therapy¹

General Recommendations^e

Laboratory values should be checked shortly before the treatment is ordered (typically 2 weeks before each cycle)²
These may include BUN, creatinine, albumin, ALP, AST, ALT, total bilirubin, WBC count with differential, hemoglobin, and platelet counts²

^eThese are general recommendations provided by representatives from the NANETS and the SNMMI who collaborated to develop a practical consensus guideline for the administration of lutetium Lu 177 dotatate. This guidance is not required per the LUTATHERA package insert and is designed to provide practical guidance on how to safely treat patients with this therapy.²
