1.1 Patients with Cancer Receiving Myelosuppressive Chemotherapy
Neulasta Onpro Kit is indicated to decrease the incidence of infection, as manifested by febrile neutropenia, in patients with non-myeloid malignancies receiving myelosuppressive anti-cancer drugs associated with a clinically significant incidence of febrile neutropenia.
Neulasta Onpro Kit is not indicated for the mobilization of peripheral blood progenitor cells for hematopoietic stem cell transplantation.
1.2 Patients with Hematopoietic Subsyndrome of Acute Radiation Syndrome
Neulasta Onpro Kit is indicated to increase survival in patients acutely exposed to myelosuppressive doses of radiation.
Neulasta Onpro Kit injection is used to treat neutropenia (low white blood cells) that is caused by cancer medicines. It is a synthetic (man-made) form of a substance that is naturally produced in your body called a colony stimulating factor. Neulasta Onpro Kit helps the bone marrow to make new white blood cells.
When certain cancer medicines are used to fight cancer cells, they also affect the white blood cells that fight infections. Neulasta Onpro Kit is used to reduce the risk of infection while you are being treated with cancer medicines.
Neulasta Onpro Kit is available only with your doctor's prescription.
Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, Neulasta Onpro Kit is used in certain patients with the following medical conditions:
- Harvesting of peripheral blood stem cells, prior to autologous stem-cell transplantation.
2.1 Patients with Cancer Receiving Myelosuppressive Chemotherapy
The recommended dosage of Neulasta Onpro Kit is a single subcutaneous injection of 6 mg administered once per chemotherapy cycle. For dosing in pediatric patients weighing less than 45 kg, refer to Table 1. Do not administer Neulasta Onpro Kit between 14 days before and 24 hours after administration of cytotoxic chemotherapy.
2.2 Patients with Hematopoietic Subsyndrome of Acute Radiation Syndrome
The recommended dose of Neulasta Onpro Kit is two doses, 6 mg each, administered subcutaneously one week apart. For dosing in pediatric patients weighing less than 45 kg, refer to Table 1. Administer the first dose as soon as possible after suspected or confirmed exposure to radiation levels greater than 2 gray (Gy). Administer the second dose one week after the first dose.
Obtain a baseline complete blood count (CBC). Do not delay administration of Neulasta Onpro Kit if a CBC is not readily available. Estimate a patient’s absorbed radiation dose (i.e., level of radiation exposure) based on information from public health authorities, biodosimetry if available, or clinical findings such as time to onset of vomiting or lymphocyte depletion kinetics.
2.3 Administration
Neulasta Onpro Kit is administered subcutaneously via a single-dose prefilled syringe for manual use or for use with the On-body Injector for Neulasta Onpro Kit which is co-packaged with a single-dose prefilled syringe. Use of the On-body Injector for Neulasta Onpro Kit is not recommended for patients with Hematopoietic Subsyndrome of Acute Radiation Syndrome. Use of the On-body Injector for Neulasta Onpro Kit has not been studied in pediatric patients.
Prior to use‚ remove the carton from the refrigerator and allow the Neulasta Onpro Kit prefilled syringe to reach room temperature for a minimum of 30 minutes. Discard any prefilled syringe left at room temperature for greater than 48 hours.
Visually inspect parenteral drug products (prefilled syringe) for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not administer Neulasta Onpro Kit if discoloration or particulates are observed.
The needle cap on the prefilled syringes contains dry natural rubber (derived from latex); persons with latex allergies should not administer these products.
Pediatric Patients weighing less than 45 kg
The Neulasta Onpro Kit prefilled syringe is not designed to allow for direct administration of doses less than 0.6 mL (6 mg). The syringe does not bear graduation marks, which are necessary to accurately measure doses of Neulasta Onpro Kit less than 0.6 mL (6 mg) for direct administration to patients. Thus, the direct administration to patients requiring dosing of less than 0.6 mL (6 mg) is not recommended due to the potential for dosing errors. Refer to Table 1.
2.4 Special Healthcare Provider Instructions for the On-body Injector for Neulasta Onpro Kit
A healthcare provider must fill the On-body Injector with Neulasta Onpro Kit using the prefilled syringe and then apply the On-body Injector for Neulasta Onpro Kit to the patient’s skin (abdomen or back of arm). The back of the arm may only be used if there is a caregiver available to monitor the status of the On-body Injector for Neulasta Onpro Kit. Approximately 27 hours after the On-body Injector for Neulasta Onpro Kit is applied to the patient’s skin, Neulasta Onpro Kit will be delivered over approximately 45 minutes. A healthcare provider may initiate administration with the On-body Injector for Neulasta Onpro Kit on the same day as the administration of cytotoxic chemotherapy, as long as the On-body Injector for Neulasta Onpro Kit delivers Neulasta Onpro Kit no less than 24 hours after administration of cytotoxic chemotherapy.
The prefilled syringe co-packaged in Neulasta Onpro Kit OnproTM kit must only be used with the On-body Injector for Neulasta Onpro Kit. The prefilled syringe contains additional solution to compensate for liquid loss during delivery through the On-body Injector for Neulasta Onpro Kit. If the prefilled syringe co-packaged in Neulasta Onpro Kit Onpro kit is used for manual subcutaneous injection, the patient will receive an overdose. If the single-dose prefilled syringe for manual use is used with the On-body Injector for Neulasta Onpro Kit, the patient may receive less than the recommended dose.
Do not use the On-body Injector for Neulasta Onpro Kit to deliver any other drug product except the Neulasta Onpro Kit prefilled syringe co-packaged with the On-body Injector for Neulasta Onpro Kit.
The On-body Injector for Neulasta Onpro Kit should be applied to intact, non-irritated skin on the arm or abdomen.
A missed dose could occur due to an On-body Injector for Neulasta Onpro Kit failure or leakage. If the patient misses a dose, a new dose should be administered by single-dose prefilled syringe for manual use, as soon as possible after detection.
Refer to the Healthcare Provider Instructions for Use for the On-body Injector for Neulasta Onpro Kit for full administration information.

There are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.Use: Labeled Indications

What other drugs will affect Neulasta Onpro Kit?
Due to the potential sensitivity of rapidly dividing myeloid cells to cytotoxic chemotherapy, Neulasta Onpro Kit should be administered approximately 24 hrs after administration of cytotoxic chemotherapy. In clinical studies, Neulasta Onpro Kit has been safely administered 14 days before chemotherapy. Concomitant use of Neulasta Onpro Kit with any chemotherapeutic agent has not been evaluated in patients. In animal models, concomitant administration of Neulasta Onpro Kit and 5-fluorouracil (5-FU) or other antimetabolites has been shown to potentiate myelosuppression.
Increased haematopoietic activity of the bone marrow in response to growth factor therapy has been associated with transient positive bone-imaging changes. This should be considered when interrupting bone-imaging results.
Possible interactions with other haematopoietic growth factors and cytokines have not been specifically investigated in clinical studies.
The potential for interaction with lithium, which also promotes the release of neutrophils, has not been specifically investigated. There is no evidence that such an interaction would be harmful.
The safety and efficacy of Neulasta Onpro Kit have not been evaluated in patients receiving chemotherapy associated with delayed myelosuppression eg, nitrosoureas.
Specific interaction or metabolism studies have not been performed, however, clinical studies have not indicated an interaction of Neulasta Onpro Kit with any other medicinal products.
Incompatibilities: Neulasta Onpro Kit is incompatible with sodium chloride solutions.

What are the possible side effects of Neulasta Onpro Kit?
Clinical Trials: In randomised clinical studies in patients with malignancy receiving Neulasta Onpro Kit after cytotoxic chemotherapy, most adverse events were caused by the underlying malignancy or cytotoxic chemotherapy.
The most frequently reported and very common study drug-related adverse effect was bone pain. Bone pain was generally of mild-to-moderate severity, transient and could be controlled in most patients with standard analgesics.
Gastrointestinal Disorders: Nausea was observed in healthy volunteers more frequently than in patients receiving chemotherapy.
Very common (≥10%) and common (≥1%, <10%) adverse effects in clinical studies are seen in the table as follows.
Laboratory Abnormalities: Reversible, mild to moderate elevations in uric acid, with no associated clinical effects, were common; reversible, mild to moderate elevations in alkaline phosphatase and lactate dehydrogenase, with no associated clinical effects, were very common in patients receiving Neulasta Onpro Kit following cytotoxic chemotherapy.
Laboratory Test: White blood cell counts (WBC) of ≥100 x 109/L have been observed in <1% of patients receiving Neulasta Onpro Kit. No adverse events directly attributable to this degree of leucocytosis have been reported. Such elevation in WBC is transient, typically seen 24-48 hrs after administration and is consistent with the pharmacodynamic effects of Neulasta Onpro Kit.
Post-Marketing: Immune System Disorders: Allergic-type reaction, including anaphylaxis, skin rash, urticaria, angioedema, dyspnoea, hypotension, erythema and flushing, occurring on initial or subsequent treatment have rarely been reported in patients receiving Neulasta Onpro Kit. In some cases, symptoms have recurred with rechallenge, suggesting a causal relationship. If a serious allergic reaction occurs, appropriate therapy should be administered, with close patient follow-up over several days. Neulasta Onpro Kit should be permanently discontinued in patients who experience a serious allergic reaction.
Gastrointestinal Disorders: Very rare cases of splenic rupture have been reported during treatment with Neulasta Onpro Kit.
Skin and Subcutaneous Tissue Disorders: Rare cases of Sweet's syndrome (acute febrile dermatosis) have been reported.
Reactions of cutaneous vasculitis have been reported in patients with cancer receiving Neulasta Onpro Kit (estimated reporting rate: 0.00038%).
Each 0.5 mL pre-filled syringe or 1 mL vial contains Pegfilgrastim 6 mg.
Neulasta Onpro Kit also contains the following excipients: Sodium acetate trihydrate, polysorbate 80, benzyl alcohol and water for injection.
Neulasta Onpro Kit is a covalent conjugate of recombinant human granulocyte colony-stimulating factor (G-CSF) (filgrastim) and monomethoxypolyethylene glycol. Filgrastim is a water-soluble 175 amino acid protein with a molecular weight of approximately 19 kiloDaltons (kD). Filgrastim is obtained from the bacterial fermentation of a strain of Escherichia coli transformed with a genetically engineered plasmid containing the human G-CSF gene. The average molecular weight of Neulasta Onpro Kit is approximately 39 kD.
Neulasta Onpro Kit is supplied as an injectable solution in pre-filled syringes and vials. The injectable solution is sterile, clear and colorless.
