DOSAGE AND ADMINISTRATION

• Lymphoseek is supplied as a Kit and must be prepared by radiolabeling with technetium Tc 99m and diluting with the supplied diluent prior to use. ( 2.3 )

• Use aseptic technique and radiation safety precautions during Lymphoseek preparation and handling. For each patient, the total injection volume and the number of sites to be injected should be known before preparing Lymphoseek. ( 2.1 , 2.3 )

• Administer 18.5 MBq (0.5 mCi) of Lymphoseek at least 15 minutes before initiating intraoperative lymphatic mapping or sentinel node biopsy procedures. Complete lymphatic mapping and sentinel node biopsy within 15 hours after Lymphoseek injection. ( 2.2 , 2.3 )

• Recommended administration routes are intradermal, subcutaneous, subareolar, and peritumoral injections. ( 2.3 )

• Each radiolabeled Lymphoseek vial contains sufficient amount to provide doses for up to four patients when prepared according to the instructions. The radiolabeled Lymphoseek is to be used within 6 hours of its preparation. ( 2.3 )

2.1 Radiation Safety - Drug Handling

Lymphoseek is a radioactive drug and should be handled with appropriate safety measures to minimize radiation exposure [see Warnings and Precautions (5.2)]. Use waterproof gloves, effective radiation shielding, and appropriate safety measures when preparing and handling Lymphoseek.

Radiopharmaceuticals should be used by or under the control of physicians who are qualified by specific training and experience in the safe use and handling of radionuclides, and whose experience and training have been approved by the appropriate governmental agency authorized to license the use of radionuclides.

2.2 Recommended Dose

The recommended dose of Lymphoseek is 18.5 MBq (0.5 mCi) as a radioactivity dose and 50 mcg as a mass dose. Administer Lymphoseek at least 15 minutes prior to initiating intraoperative lymphatic mapping and sentinel node biopsy; complete these procedures within 15 hours after Lymphoseek injection.

Route of Administration and Injection Method:

The route of administration depends on the tumor location and the planned injection technique and includes: subcutaneous, intradermal, subareolar, or peritumoral injection.

Lymphoseek may be administered to a patient as a single injection or as multiple injections. The recommended total injection volume for each patient (Table 1) is 0.1 mL administered in a single syringe; 0.5 mL administered in a single syringe or in multiple syringes (0.1 mL to 0.25 mL each); or 1 mL administered in multiple syringes (0.2 mL to 0.5 mL each).

The lymphatic system architecture and function may be changed by prior surgery, radiation, edema, inflammation or metastatic disease, and may result in changes to lymph node localization by a radiopharmaceutical or other tracers, including colorimetric agents. Avoid injections into biopsy wound areas that show evidence of edema or inflammation.

In animal studies, locally injected anesthetics have been reported to reduce lymphatic flow. Concomitant administration of local anesthetics with Lymphoseek is not recommended and may impair the lymph nodal mapping.

2.3 Drug Preparation

General Considerations:

• Kit for the preparation of Lymphoseek contains five sets of two vials: a Tilmanocept Powder vial and a DILUENT for Lymphoseek vial. Tilmanocept Powder vial contains 250 mcg of tilmanocept from which 50 mcg is intended for administration to a patient. The DILUENT for Lymphoseek vial contains 4.5 mL of sterile buffered saline. It is used to dilute Lymphoseek after the radiolabeling procedure. The amount of diluent used varies, depending on the total injection volume and the number of syringes used for each patient.

• Tilmanocept Powder vial contains 250 mcg of tilmanocept from which 50 mcg is intended for administration to a patient.

• The DILUENT for Lymphoseek vial contains 4.5 mL of sterile buffered saline. It is used to dilute Lymphoseek after the radiolabeling procedure. The amount of diluent used varies, depending on the total injection volume and the number of syringes used for each patient.

• The vial components of the Kit for the preparation of Lymphoseek are intended solely for use in the preparation of Lymphoseek (technetium Tc 99m tilmanocept) Injection. Do not administer the unprepared vial components of the Kit directly to a patient.

• Follow aseptic procedures during preparation and administration.

Drug Preparation Instructions:

Prior to preparation of Lymphoseek, determine the planned injection technique and the number of injections that will be used for a given patient. For each injection prepare a separate syringe. Based on the planned number of injection syringes and the planned total injection volume per patient, determine (from Table 1 below) the Reconstituted Vial Volume of radiolabeled Lymphoseek.

Once the Reconstituted Vial Volume is established, use the following steps to prepare radiolabeled Lymphoseek:

Radiolabeling:

a. Inspect the Tilmanocept Powder vial for any damage. Do not use if vial integrity appears compromised. Do not vent the Tilmanocept Powder vial prior to or during radiolabeling.

b. Use Technetium Tc 99m pertechnetate, sodium injection solution from a technetium Tc 99m generator within 8 hours of its elution.

c. Using a sterile syringe, aseptically draw approximately 92.5 MBq (2.5 mCi) of Technetium Tc 99m pertechnetate sodium injection solution in either about 0.35 mL volume (for 0.5 mL Reconstituted Vial Volume) or about 0.7 mL volume (for 2.5 mL or 5 mL Reconstituted Vial Volume). Assay the syringe for technetium Tc 99m activity in a dose calibrator.

d. Write the radioactivity amount, the Reconstituted Vial Volume, date and time, expiration time and lot number in the space provided on the radioactive product vial label and affix it to the Tilmanocept Powder vial. Place the vial in a radiation shield and sanitize the septum with alcohol wipe.

e. Aseptically add Technetium Tc 99m pertechnetate, sodium injection solution (from step d above) to the Tilmanocept Powder vial. Without withdrawing the needle, remove an equal volume of headspace gas. Do not vent.

f. Remove the needle, gently shake the vial to mix the contents, and then let it stand at room temperature for at least 15 minutes.

Reconstitution:

g. Aseptically add the supplied DILUENT for Lymphoseek to the radiolabeled product in the Tilmanocept Powder vial to bring the volume to the Reconstituted Vial Volume of 0.5 mL, 2.5 mL, or 5 mL prior to filling the patient dose in syringe(s). To normalize pressure, withdraw an equal volume of headspace gas.

h. Each Lymphoseek vial, once radiolabeled and reconstituted, would contain sufficient amount to provide doses for up to four patients when prepared according to the instructions.

Quality Control of Radiolabeled Solution:

i. Assay the reconstituted vial for total radioactivity using a dose calibrator. Write the technetium Tc 99m activity concentration, total volume, assay time and date, expiration time, and lot number on the shield label supplied with the Kit. Affix the label to the shield.

j. Determine the radiochemical purity of the radiolabeled product [see Dosage and Administration (2.4)]. Do not use if the radiochemical purity is less than 90%.

k. Withdraw the required volume of the radiolabeled product into the required number of syringes. Assay the syringe(s) in a dose calibrator. Write the radioactivity amount, date and time of assay, volume, and expiration time (this is not to exceed 6 hours from preparation time) on the supplied syringe label and affix it to the syringe(s).

Duration of Use and Storage of Radiolabeled Solution:

l. Store the radiolabeled Lymphoseek in radiation shielding at room temperature.

m. Use the radiolabeled Lymphoseek within 6 hours of preparation. Discard the unused radiolabeled Lymphoseek.

2.4 Determination of Radiochemical Purity of Radiolabeled Lymphoseek

Determine radiochemical purity of the reconstituted radiolabeled Lymphoseek by Instant Thin Layer Chromatography (ITLC) using either Whatman Grade 1, 3MM, 31ET Chr or Biodex 150-001 Red Strips (cellulose chromatography paper) using the following method:

1. Mark the chromatographic strip for origin, mid and solvent front lines with a pencil as shown below:

2. Apply a small drop (3 - 10 microliters) of the reconstituted product at the center of the origin line chromatography strip. Let the product spot dry.

3. Place the strip into a chromatography chamber containing 1 mL of acetone as the developing solvent. Allow the solvent to migrate to the solvent front line (5 cm from the bottom of the Whatman strips and 3.5 cm for the Biodex strip). Remove the strip from the chamber, let it dry and cut it in half. Count each half of the strip with a suitable radioactivity counting apparatus (dose calibrator or multichannel analyzer).

4. Calculate the percent radiochemical purity (% RCP) as follows: % RCP = Counts (activity) in bottom half x 100 Counts (activity) in bottom half + Counts (activity) in top half

5. Do not use the reconstituted Lymphoseek if the radiochemical purity is less than 90%.

2.5 Lymphatic Mapping and Sentinel Lymph Node Biopsy Following Injection of Lymphoseek

• Lymphoscintigraphy may be considered to help plan the lymph node mapping procedures. In clinical studies, preoperative lymphoscintigraphy was performed in most patients; the extent to which lymphoscintigraphy contributed to the success of the mapping procedures was not established [see Clinical Studies (14)] .

• Use a hand-held gamma counter to identify nodes that concentrated the injected radioactivity.

• For intraoperative lymphatic mapping, first measure the background radioactivity counts from tissue at least 20 centimeters distal to the injection site. The three sigma threshold (background radioactivity counts plus three times the square root of the mean background count) may be used as an estimate of the threshold for positive localization of Lymphoseek, as exemplified in Table 2.

• Lymphoseek is intended to supplement palpation, visual inspection, and other procedures important to lymph node mapping and sentinel node biopsy. Intraoperative lymphatic mapping and sentinel node biopsy using gamma detection of Lymphoseek within lymph nodes should be initiated no sooner than 15 minutes following injection. In clinical studies of breast cancer and melanoma, patients also received a concomitant blue dye tracer for comparative detection of lymph nodes. While most lymph nodes were detected with Lymphoseek, some were detected only with the blue dye tracer or only with palpation [see Clinical Studies (14)] .

2.6 Radiation Dosimetry

The radiation doses to organs and tissues of a patient weighing 70 kg given 18.5 MBq (0.5 mCi) of Lymphoseek are shown in Table 3.

DOSAGE FORMS AND STRENGTHS

The Kit for preparation of Lymphoseek (technetium Tc 99m tilmanocept) Injection is supplied as five Tilmanocept Powder vials each containing 250 mcg tilmanocept and five DILUENT for Lymphoseek vials each containing 4.5 mL of sterile buffered saline. After radiolabeling with technetium Tc 99m, Lymphoseek contains approximately 92.5 MBq (2.5 mCi) and 250 mcg technetium Tc 99m tilmanocept in 0.5 mL to 5 mL total volume.

CONTRAINDICATIONS

None.

WARNINGS AND PRECAUTIONS

Hypersensitivity: Ask patients about prior reactions to drugs, especially dextran or modified forms of dextran. Observe for hypersensitivity signs and symptoms following Lymphoseek injection. Have resuscitation equipment and trained personnel available at the time of Lymphoseek administration. (5.1)

5.1 Hypersensitivity Reactions

Lymphoseek may pose a risk of hypersensitivity reactions due to its chemical similarity to dextran [see Description (11)]. Serious hypersensitivity reactions have been associated with dextran and modified forms of dextran (such as iron dextran drugs). In clinical trials, no serious hypersensitivity reactions were reported.

Before administering Lymphoseek, ask patients about prior hypersensitivity reactions to drugs, especially to dextran and modified forms of dextran. Have resuscitation equipment and trained personnel immediately available at the time of Lymphoseek administration.

5.2 Radiation Risks

Any radiation-emitting product may increase the risk for cancer, especially in pediatric patients. Adhere to the dose recommendations and ensure safe handling to minimize the risk for excessive radiation exposure to either patients or health care workers.

USE IN SPECIFIC POPULATIONS

• Pregnancy: Use only if clearly needed. ( 8.1 )

• Nursing mothers: Pump and discard milk for at least 60 hours following administration of Lymphoseek. ( 8.3 )

8.1 Pregnancy

Pregnancy Category C

Risk Summary:

There are no adequate or well-controlled studies of Lymphoseek in pregnant women.Additionally, animal reproduction studies have not been conducted with technetium Tc 99m tilmanocept. However, all radiopharmaceuticals, including Lymphoseek, have a potential to cause fetal harm. The likelihood of fetal harm depends on the stage of fetal development and the radiopharmaceutical dose. Lymphoseek should be given to a pregnant woman only if clearly needed.

8.3 Nursing Mothers

It is not known whether technetium Tc 99m tilmanocept is present in human milk. Based on the half-life of technetium Tc 99m a nursing woman should pump and discard milk for at least 60 hours (ten half-lives) after administration of Lymphoseek. Exercise caution when administering Lymphoseek to a nursing woman.

8.4 Pediatric Use

Safety and effectiveness of Lymphoseek in pediatric patients have not been established.

8.5 Geriatric Use

Of the 553 patients enrolled in clinical studies of breast cancer, melanoma, and SCC of oral cavity, skin, and lip, 179 (32%) were aged 65 or older. Review of the clinical data, including evaluation of the frequency of adverse reactions, has not identified differences in safety or efficacy between elderly patients (65 to 90 years of age) and younger patients (18 to 65 years of age).

8.6 Females of Reproductive Potential

In females of reproductive potential, Lymphoseek administration should be performed within the ten days following the onset of menses or a pregnancy test should be performed within 48 hours prior to the Lymphoseek administration.

DESCRIPTION

11.1 Chemical Characteristics

The active ingredient in Lymphoseek, a radioactive diagnostic agent, is technetium Tc 99m tilmanocept. Technetium Tc 99m binds to the diethylenetriaminepentaacetic acid (DTPA) moieties of the tilmanocept molecule.

• Chemically, technetium Tc 99m tilmanocept consists of technetium Tc 99m, dextran 3-[(2-aminoethyl)thio]propyl 17-carboxy-10,13,16-tris(carboxymethyl)-8-oxo-4-thia-7,10,13,16-tetraazaheptadec-1-yl 3-[[2-[[1-imino-2-(D-mannopyranosylthio)ethyl]amino]ethyl]thio]propyl ether complexes.

• The molecular formula of technetium Tc 99m tilmanocept is [C 6 H 10 O 5 ] n . (C 19 H 28 N 4 O 9 S 99m Tc) b . (C 13 H 24 N 2 O 5 S 2 ) c . (C 5 H 11 NS) a . It contains 3-8 conjugated DTPA (diethylenetriaminepentaacetic acid) molecules (b); 12-20 conjugated mannose molecules (c) with 0-17 amine side chains (a) remaining free.

• The calculated average molecular weight of tilmanocept ranges from 15,281 to 23,454 g/mol.

• Technetium Tc 99m tilmanocept has the following structural formula:

Lymphoseek (technetium Tc 99m tilmanocept) Injection is supplied as a Kit which contains:

• Tilmanocept Powder vial contains the non-radioactive ingredients needed to produce technetium Tc 99m tilmanocept. The vial contains a sterile, non-pyrogenic, white to off-white lyophilized powder (under nitrogen) that consists of a mixture of 250 mcg tilmanocept, 20 mg trehalose dihydrate, 0.5 mg glycine, 0.5 mg sodium ascorbate, and 0.075 mg stannous chloride dihydrate.

• DILUENT for Lymphoseek contains a preservative formulated for Lymphoseek. The vial contains 4.5 mL sterile buffered saline consisting of 0.04% (w/v) potassium phosphate, 0.11% (w/v) sodium phosphate (heptahydrate), 0.5% (w/v) sodium chloride, and 0.4% (w/v) phenol. The pH is 6.8 - 7.2. No other diluent should be used.

11.2 Physical Characteristics

Technetium Tc 99m decays by isomeric transition with a physical half-life of approximately 6 hours. The principal photon that is useful for detection and imaging studies is listed in Table 4.

11.3 External Radiation

The linear mass energy absorption attenuation coefficient for Tc 99m is 18.9 cm-1. The first half-value layer is 0.037 cm of lead (Pb). The use of a 0.25 cm thick standard radiation lead shield will attenuate the radiation emitted by millicurie amounts of technetium Tc 99m by a factor of about 100. A range of values for the relative attenuation of the radiation of technetium Tc 99m that results with various thicknesses of lead shielding are displayed in Table 5.

To correct for physical decay of the radionuclide, the fractions that remain at selected intervals after the time of calibration are shown in Table 6.

CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Lymphoseek (technetium Tc 99m tilmanocept) is a radioactive diagnostic agent. It accumulates in lymphatic tissue and selectively binds to mannose binding receptors (CD206) located on the surface of macrophages and dendritic cells. Technetium Tc 99m tilmanocept is a macromolecule consisting of multiple units of diethylenetriaminepentaacetic acid (DTPA) and mannose, each covalently attached to a 10 kDa dextran backbone. The mannose acts as a ligand for the receptor, and the DTPA serves as a chelating agent for labeling with technetium Tc 99m.

12.2 Pharmacodynamics

In in vitro studies, technetium Tc 99m tilmanocept exhibited binding to human mannose binding receptors with a primary binding site affinity of Kd = 2.76 x 10-11 M.

In clinical studies, technetium Tc 99m tilmanocept has been detectable in lymph nodes within 10 minutes and up to 30 hours after injection.

12.3 Pharmacokinetics

In dose-ranging clinical studies, injection site clearance rates were similar across all Lymphoseek doses (4 to 200 mcg) with a mean elimination rate constant in the range of 0.222 to 0.396/hr, resulting in a drug half-life at the injection site of 1.8 to 3.1 hours.

The amount of the accumulated radioactive dose in the liver, kidney, and bladder reached a maximum 1 hour post administration of Lymphoseek and was approximately 1% to 2% of the injected dose in each tissue.

NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Studies to assess the carcinogenicity potential of tilmanocept have not been conducted. Tilmanocept was not mutagenic in vitro in the Ames bacterial mutation assay and in the in vitro mouse lymphoma test, and was negative in the in vivo micronucleus test in mice.

Studies on reproductive fertility have not been conducted.

CLINICAL STUDIES

14.1 Overview of Clinical Studies

• The efficacy and safety of Lymphoseek were assessed in three open-label, multicenter, single arm trials of patients with melanoma, breast cancer, or squamous cell carcinoma (SCC) of the oral cavity, skin, and lip (Studies 1, 2, and 3). Prior to the lymph node mapping procedures or sentinel lymph node biopsy, patients had no known regional nodal or metastatic disease by standard clinical staging criteria.

• In Studies 1 and 2, Lymphoseek was evaluated in patients with breast cancer and melanoma. Diagnostic efficacy was determined by the number of histology-confirmed lymph nodes detected by Lymphoseek and/or blue dye. Lymphoseek was injected into patients at least 15 minutes prior to the scheduled surgery, while blue dye was injected shortly prior to initiation of the surgery. Lymphatic mapping was performed intraoperatively using a hand-held gamma detection probe followed by excision of lymph nodes identified by Lymphoseek, blue dye, or the surgeon's visual and palpation examination. The resected lymph nodes were evaluated by histopathology. In Study 1, of 179 patients who received Lymphoseek, 94 (53%) had known or suspected breast cancer and 85 (47%) had known or suspected melanoma. The median age was 59 years (range 20 to 90 years) and most (72%) were women. In Study 2, of 153 patients who received Lymphoseek, 77 (50%) had known or suspected breast cancer and 76 (50%) had known or suspected melanoma. The median age was 61 years (range 26 to 88 years) and most (68%) were women.

• In Study 1, of 179 patients who received Lymphoseek, 94 (53%) had known or suspected breast cancer and 85 (47%) had known or suspected melanoma. The median age was 59 years (range 20 to 90 years) and most (72%) were women.

• In Study 2, of 153 patients who received Lymphoseek, 77 (50%) had known or suspected breast cancer and 76 (50%) had known or suspected melanoma. The median age was 61 years (range 26 to 88 years) and most (68%) were women.

• In Study 3, Lymphoseek was evaluated mostly in patients with SCC of the oral cavity (T1-T4a, N0, M0). Diagnostic efficacy was determined by the patient level false negative rate of sentinel lymph node detection by Lymphoseek as confirmed by pathologic assessment of lymph nodes removed during a planned elective neck dissection (END). Lymphoseek was injected into patients at least 15 minutes prior to the scheduled surgery. Lymphatic mapping was performed intraoperatively using a hand-held gamma detection probe followed by excision of sentinel lymph nodes identified by Lymphoseek. Then, additional lymph nodes were removed during the END based upon tumor location and surgical practice. All resected lymph nodes (sentinel and non-sentinel) were evaluated for histopathology at the local site. Lymphoseek-identified nodes determined negative for cancer were further evaluated by a central pathology laboratory using additional step sectioning and cytokeratin staining. Of the 85 patients who received Lymphoseek, 79 (93%) had intraoral SCC and 6 (7%) had cutaneous SCC. The median age was 59 years (range 23 to 87 years) and most (75%) were men.

• Of the 85 patients who received Lymphoseek, 79 (93%) had intraoral SCC and 6 (7%) had cutaneous SCC. The median age was 59 years (range 23 to 87 years) and most (75%) were men.

• Approximately 93% of patients from the three studies underwent preoperative lymphoscintigraphy to help identify nodal basins and to facilitate intraoperative identification of lymph nodes.

14.2 Localization of Lymph Nodes in Patients with Breast Cancer or Melanoma

In Studies 1 and 2 in melanoma and breast cancer, efficacy analyses were based upon comparisons of the number and proportion of resected lymph nodes that contained a lymph node tracer (Lymphoseek and/or blue dye) or neither tracer. Evaluable lymph nodes were resected from 176 Study 1 patients and 152 Study 2 patients who received Lymphoseek at the dose of 0.5 to 2.0 mCi in 50 mcg administered 15 minutes to 30 hours prior to surgery. Table 7 shows the distribution of resected lymph nodes by the presence or absence of a tracer. Most of the resected lymph nodes were identified by either Lymphoseek (LS) or blue dye (BD) or both. Significantly more resected lymph nodes were identified by Lymphoseek in comparison to blue dye.

14.3 Guiding Sentinel Lymph Node Biopsy in Patients with SCC of the Oral Cavity, Skin, and Lip

In Study 3 in patients with SCC of the oral cavity (n=79), skin (n=5), and lip (n=1), sentinel lymph node pathology findings were compared to the pathology findings of all other lymph nodes removed during the scheduled elective node dissection to determine the false negative rate of Lymphoseek. Thirty-nine patients were determined to have pathology-positive regional lymph nodes. In these patients, the per patient false negative rate was 2.6% (95% CI: 0.06% to 13.5%). In this study the pathology positive nodes were found in patients with SCC of the oral cavity.
