2 DOSAGE AND ADMINISTRATION

2.1 Dosage in Patients with Cancer Receiving Myelosuppressive Chemotherapy or Induction and/or Consolidation Chemotherapy for AML

The recommended starting dosage of NIVESTYM is 5 mcg/kg/day‚ administered as a single daily injection by subcutaneous injection‚ by short intravenous infusion (15 to 30 minutes)‚ or by continuous intravenous infusion. Obtain a complete blood count (CBC) and platelet count before instituting NIVESTYM therapy and monitor twice weekly during therapy. Consider dose escalation in increments of 5 mcg/kg for each chemotherapy cycle‚ according to the duration and severity of the absolute neutrophil count (ANC) nadir. Recommend stopping NIVESTYM if the ANC increases beyond 10‚000/mm3 [see Warnings and Precautions (5.10)].

Administer NIVESTYM at least 24 hours after cytotoxic chemotherapy. Do not administer NIVESTYM within the 24-hour period prior to chemotherapy [see Warnings and Precautions (5.13)]. A transient increase in neutrophil count is typically seen 1 to 2 days after initiation of NIVESTYM therapy. Therefore, to ensure a sustained therapeutic response‚ administer NIVESTYM daily for up to 2 weeks or until the ANC has reached 10‚000/mm3 following the expected chemotherapy-induced neutrophil nadir. The duration of NIVESTYM therapy needed to attenuate chemotherapy-induced neutropenia may be dependent on the myelosuppressive potential of the chemotherapy regimen employed.

2.2 Dosage in Patients with Cancer Undergoing Bone Marrow Transplantation

The recommended dosage of NIVESTYM following bone marrow transplantation (BMT) is 10 mcg/kg/day given as an intravenous infusion no longer than 24 hours. Administer the first dose of NIVESTYM at least 24 hours after cytotoxic chemotherapy and at least 24 hours after bone marrow infusion. Monitor CBCs and platelet counts frequently following marrow transplantation.

During the period of neutrophil recovery‚ titrate the daily dosage of NIVESTYM against the neutrophil response (see Table 1).

If ANC decreases to less than 1,000/mm3 at any time during the 5 mcg/kg/day administration‚ increase NIVESTYM to 10 mcg/kg/day‚ and then follow the above steps.

When ANC greater than 1,000/mm3 for 3 consecutive days

Reduce to 5 mcg/kg/day*

Then, if ANC remains greater than 1,000/mm3 for 3 more consecutive days

Discontinue NIVESTYM

Then, if ANC decreases to less than 1,000/mm3

Resume at 5 mcg/kg/day

2.3 Dosage in Patients Undergoing Autologous Peripheral Blood Progenitor Cell Collection and Therapy

The recommended dosage of NIVESTYM for the mobilization of autologous peripheral blood progenitor cells (PBPC) is 10 mcg/kg/day given by subcutaneous injection. Administer NIVESTYM for at least 4 days before the first leukapheresis procedure and continue until the last leukapheresis. Although the optimal duration of NIVESTYM administration and leukapheresis schedule have not been established‚ administration of filgrastim for 6 to 7 days with leukaphereses on days 5‚ 6‚ and 7 was found to be safe and effective [see Clinical Studies (14.4)]. Monitor neutrophil counts after 4 days of NIVESTYM‚ and discontinue NIVESTYM if the white blood cell (WBC) count rises to greater than 100‚000/mm3.

2.4 Dosage in Patients with Severe Chronic Neutropenia

Prior to starting NIVESTYM in patients with suspected chronic neutropenia, confirm the diagnosis of severe chronic neutropenia (SCN) by evaluating serial CBCs with differential and platelet counts‚ and evaluating bone marrow morphology and karyotype. The use of NIVESTYM prior to confirmation of a correct diagnosis of SCN may impair diagnostic efforts and may thus impair or delay evaluation and treatment of an underlying condition‚ other than SCN‚ causing the neutropenia.

The recommended starting dosage in patients with Congenital Neutropenia is 6 mcg/kg as a twice daily subcutaneous injection and the recommended starting dosage in patients with Idiopathic or Cyclic Neutropenia is 5 mcg/kg as a single daily subcutaneous injection.

Dosage Adjustments in Patients with Severe Chronic Neutropenia

Chronic daily administration is required to maintain clinical benefit. Individualize the dosage based on the patient's clinical course as well as ANC. In the SCN postmarketing surveillance study, the reported median daily doses of filgrastim were: 6 mcg/kg (congenital neutropenia), 2.1 mcg/kg (cyclic neutropenia), and 1.2 mcg/kg (idiopathic neutropenia). In rare instances, patients with congenital neutropenia have required doses of filgrastim greater than or equal to 100 mcg/kg/day.

Monitor CBCs for Dosage Adjustments

During the initial 4 weeks of NIVESTYM therapy and during the 2 weeks following any dosage adjustment‚ monitor CBCs with differential and platelet counts. Once a patient is clinically stable‚ monitor CBCs with differential and platelet counts monthly during the first year of treatment. Thereafter, if the patient is clinically stable, less frequent routine monitoring is recommended.

2.5 Important Administration Instructions

Patient self-administration and administration by a caregiver may benefit from training by a healthcare professional. Training should aim to demonstrate to those patients and caregivers how to measure the dose using the prefilled syringe, and the focus should be on ensuring that a patient or caregiver can successfully perform all of the steps in the Instructions for Use of NIVESTYM prefilled syringe with BD UltraSafe Plus™ Passive Needle Guard. If a patient or caregiver is not able to demonstrate that they can measure the dose and administer the product successfully, you should consider whether the patient is an appropriate candidate for self-administration of NIVESTYM [see Instructions for Use].

NIVESTYM prefilled syringe with BD UltraSafe Plus™ Passive Needle Guard is not designed to allow for direct administration of doses of less than 0.3 mL (180 mcg). The spring-mechanism of the needle guard apparatus affixed to the prefilled syringe interferes with the visibility of the graduation markings on the syringe barrel corresponding to 0.1 mL and 0.2 mL. The visibility of these markings is necessary to accurately measure doses of NIVESTYM less than 0.3 mL (180 mcg) for direct administration. Thus, the direct administration to patients requiring doses of less than 0.3 mL (180 mcg) is not recommended due to the potential for dosing errors. For direct administration of doses less than 0.3 mL (180 mcg) use NIVESTYM single-dose vial.

NIVESTYM is supplied in single-dose vials (for subcutaneous use or intravenous infusion) and single-dose prefilled syringes (for subcutaneous use) [see Dosage Forms and Strengths (3)]. Prior to use‚ remove the vial or prefilled syringe from the refrigerator and allow NIVESTYM to reach room temperature for a minimum of 30 minutes. If not used immediately, the vial or prefilled syringe may be stored at room temperature [between 20°C to 25°C (68°F to 77°F)] for up to 24 hours. Discard any vial or prefilled syringe left at room temperature for greater than 24 hours. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit (the solution is clear and colorless). Do not administer NIVESTYM if particulates or discoloration are observed.

Discard unused portion of NIVESTYM in vials or prefilled syringes; do not re-enter the vial. Do not save unused drug for later administration.

Subcutaneous Injection

Inject NIVESTYM subcutaneously in the outer area of upper arms, abdomen, thighs, or upper outer areas of the buttock. If patients or caregivers are to administer NIVESTYM, instruct them in appropriate injection technique and ask them to follow the subcutaneous injection procedures in the Instructions for Use for the vial or prefilled syringe [see Patient Counseling Information (17)].

Training by the healthcare provider should aim to demonstrate to those patients and caregivers how to measure the dose of NIVESTYM, and the focus should be on ensuring that a patient or caregiver can successfully perform all of the steps in the Instructions for Use for the vial or prefilled syringe. If a patient or caregiver is not able to demonstrate that they can measure the dose and administer the product successfully, you should consider whether the patient is an appropriate candidate for self-administration of NIVESTYM or whether the patient would benefit from a different NIVESTYM presentation. If a patient or caregiver experiences difficulty measuring the required dose, especially if it is other than the entire contents of the NIVESTYM prefilled syringe, use of the NIVESTYM vial may be considered.

If the patient or caregiver misses a dose of NIVESTYM, instruct them to contact their healthcare provider.

Administration Instructions for the Prefilled Syringe

The NIVESTYM syringe plunger stopper and needle cover are not made with natural rubber latex.

Administration Instructions for Dilution (Vial Only)

If required for intravenous administration‚ NIVESTYM (vial only) may be diluted in 5% Dextrose Injection, USP from a concentration of 300 mcg/mL to 5 mcg/mL (do not dilute to a final concentration less than 5 mcg/mL). NIVESTYM diluted to concentrations from 5 mcg/mL to 15 mcg/mL should be protected from adsorption to plastic materials by the addition of Albumin (Human) to a final concentration of 2 mg/mL. When diluted in 5% Dextrose Injection, USP or 5% Dextrose plus Albumin (Human)‚ NIVESTYM is compatible with glass bottles‚ polyvinyl chloride (PVC) and polyolefin intravenous bags‚ and polypropylene syringes. Do not dilute with saline at any time because the product may precipitate.

Diluted NIVESTYM solution can be stored at room temperature for up to 24 hours. This 24-hour time period includes the time during room temperature storage of the infusion solution and the duration of the infusion.

What is NIVESTYM?

NIVESTYM is a man-made form of granulocyte colony-stimulating factor (G-CSF). G-CSF is a substance produced by the body. It stimulates the growth of neutrophils, a type of white blood cell important in the body's fight against infection.

Do not take NIVESTYM if you have had a serious allergic reaction to human G-CSFs such as filgrastim products or pegfilgrastim products.

Before you take NIVESTYM, tell your healthcare provider about all of your medical conditions, including if you:

•
have a sickle cell disorder.
•
have kidney problems.
•
are receiving radiation therapy.
•
are pregnant or plan to become pregnant. It is not known if NIVESTYM will harm your unborn baby.
•
are breastfeeding or plan to breastfeed. It is not known if NIVESTYM passes into your breast milk.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

How will I receive NIVESTYM?

•
NIVESTYM injections can be given by a healthcare provider by intravenous (IV) infusion or under your skin (subcutaneous injection). Your healthcare provider may decide subcutaneous injections can be given at home by you or your caregiver. If NIVESTYM is given at home, see the detailed "Instructions for Use" that comes with your NIVESTYM for information on how to prepare and inject a dose of NIVESTYM.
•
You and your caregiver should be shown how to prepare and inject NIVESTYM before you use it, by your healthcare provider.
•
You should not try to inject a dose of NIVESTYM less than 0.3 mL (180 mcg) from a NIVESTYM prefilled syringe. A dose less than 0.3 mL cannot be accurately measured using the NIVESTYM prefilled syringe.
•
Your healthcare provider will tell you how much NIVESTYM to inject and when to inject it. Do not change your dose or stop NIVESTYM unless your healthcare provider tells you to.
•
If you are receiving NIVESTYM because you are also receiving chemotherapy, your dose of NIVESTYM should be injected at least 24 hours before or 24 hours after your dose of chemotherapy. Your healthcare provider will do blood tests to monitor your white blood cell count, and if necessary, adjust your NIVESTYM dose.
•
If you miss a dose of NIVESTYM, talk to your healthcare provider about when you should give your next dose.

What are the possible side effects of NIVESTYM?

NIVESTYM may cause serious side effects, including:

•
Spleen rupture. Your spleen may become enlarged and can rupture. A ruptured spleen can cause death. Call your healthcare provider right away if you have pain in the left upper stomach (abdomen) area or your left shoulder.
•
A serious lung problem called acute respiratory distress syndrome (ARDS). Call your healthcare provider or get emergency medical help right away if you have shortness of breath with or without a fever, trouble breathing, or a fast rate of breathing.
•
Serious allergic reactions. NIVESTYM can cause serious allergic reactions. These reactions can cause a rash over your whole body, shortness of breath, wheezing, dizziness, swelling around your mouth or eyes, fast heart rate, and sweating. If you have any of these symptoms, stop using NIVESTYM and call your healthcare provider or get emergency medical help right away.
•
Sickle cell crises. You may have a serious sickle cell crisis, which could lead to death, if you have a sickle cell disorder and receive NIVESTYM. Call your healthcare provider right away if you have symptoms of sickle cell crisis such as pain or difficulty breathing.
•
Kidney injury (glomerulonephritis). NIVESTYM can cause kidney injury. Call your healthcare provider right away if you develop any of the following symptoms:
o
swelling of your face or ankles
o
blood in your urine or dark colored urine
o
you urinate less than usual
•
Capillary leak syndrome. NIVESTYM can cause fluid to leak from blood vessels into your body's tissues. This condition is called "Capillary Leak Syndrome" (CLS). CLS can quickly cause you to have symptoms that may become life-threatening. Get emergency medical help right away if you develop any of the following symptoms:
o
swelling or puffiness and are urinating less than usual
o
trouble breathing
o
swelling of your stomach area (abdomen) and feeling of fullness
o
dizziness or feeling faint
o
a general feeling of tiredness
•
Myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML).
o
NIVESTYM may increase the risk of developing a precancerous condition called MDS or a type of blood cancer called AML in people who were born with low white blood cell counts (congenital neutropenia).
o
If you have breast cancer or lung cancer, when NIVESTYM is used with chemotherapy and radiation therapy, or with radiation therapy only, you may have an increased risk of developing MDS or AML.
o
Symptoms of MDS and AML may include tiredness, fever, and easy bruising or bleeding.
o
Call your healthcare provider if you develop any of these symptoms during treatment with NIVESTYM.
•
Decreased platelet count (thrombocytopenia). Your healthcare provider will check your blood during treatment with NIVESTYM. Tell your healthcare provider if you have unusual bleeding or bruising during treatment with NIVESTYM. This could be a sign of decreased platelet counts, which may reduce the ability of your blood to clot.
•
Increased white blood cell count (leukocytosis). Your healthcare provider will check your blood during treatment with NIVESTYM.
•
Inflammation of your blood vessels (cutaneous vasculitis). Tell your healthcare provider right away if you develop purple spots or redness of your skin.
•
Inflammation of the aorta (aortitis). Inflammation of the aorta (the large blood vessel which transports blood from the heart to the body) has been reported in patients who received NIVESTYM. Symptoms may include fever, abdominal pain, feeling tired, and back pain. Call your healthcare provider if you experience these symptoms.

The most common side effects experienced in patients receiving NIVESTYM include:

•
Patients with cancer receiving chemotherapy: fever, pain, rash, cough, and shortness of breath
•
Patients with acute myeloid leukemia receiving chemotherapy: pain, nose bleed, and rash
•
Patients with cancer receiving chemotherapy followed by bone marrow transplant: rash
•
Patients who are having their own blood cells collected: bone pain, fever, and headache
•
Patients with severe chronic neutropenia: pain, decreased red blood cells, nose bleed, diarrhea, reduced sensation, and hair loss

These are not all the possible side effects of NIVESTYM. Call your healthcare provider for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
