Neulasta® Onpro® Kit (pegfilgrastim) injection
Prescribing Information | Instructions for Use |
Neulasta® 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® is not indicated for the mobilization of peripheral blood progenitor cells for hematopoietic stem cell transplantation.
Please see additional Important Safety Information below.
31%, p = 0.01
In a Real-World Study with nearly 11,000 patients
Delivering pegfilgrastim via PFS resulted in a significantly higher risk of FN vs Onpro®2
Patients receiving Neulasta® via PFS experienced a 31% increased risk of FN vs Neulasta® Onpro®2
Across all cycles of chemotherapy, the FN risk associated with PFS was 1.7% (n = 455) vs 1.3% (n = 126) for Neulasta® Onpro®2
†FN was defined as:
  • Inpatient: Diagnosis of neutropenia AND (fever OR inpatient diagnosis of infection)
  • Outpatient: Diagnosis of neutropenia AND (fever OR diagnosis of infection AND prescribed antimicrobials)
FN = temperature ≥ 38.2°C and absolute neutrophil count < 0.5 x 109/L.
PFS = prefilled syringe; FN = febrile neutropenia.
Important Safety Information1
Neulasta® is contraindicated in patients with a history of serious allergic reactions to pegfilgrastim or filgrastim
Reactions have included anaphylaxis
Please see additional Important Safety Information below.
Real-World Study Design2
A retrospective study designed to compare the incidence of FN associated with Neulasta® Onpro® vs Neulasta ® PFS among patients receiving myelosuppressive chemotherapy. The study included 35,856 cycles of chemotherapy in which Neulasta® was administered (9395 Neulasta ® Onpro® and 26,461 PFS administrations).
Patients were followed for 6 to 12 months following the start of the first chemotherapy cycle. The study period was 1/1/16-9/30/18
Data Source: MarketScan® Commercial Claims and Encounters/Medicare Supplemental and Coordination of Benefits Databases
Real-World Study Limitations
Retrospective analysis that did not control for additional variables that may influence the incidence of FN
Database was not sufficient to understand root causes for observed lower rate of FN for patients receiving Onpro®. Potential reasons may include:
Improved compliance (Onpro® more frequently received on correct day)
Improved adherence (Onpro® received over more cycles)
Greater utilization of G-CSF support for patients
G-CSF = granulocyte colony-stimulating factor.
Pivotal trial study design and results3
Phase 3, multicenter, multinational, double-blind, placebo-controlled trial of patients with breast cancer (Neulasta® [n = 463] or placebo [n = 465]) receiving 100 mg/m2 docetaxel Q3W for up to 4 cycles. The key endpoint was the percentage of patients who developed FN (Neulasta® 1% versus placebo 17%, P < 0.001). Also, secondary endpoints were lower for Neulasta ®-treated patients as compared to placebo-treated patients (the incidence of hospitalization [1% versus 14%] and IV anti-infective use [2% versus 10%]).
Q3W = once every 3 weeks; IV = intravenous.
Neulasta® Onpro® provides protection from FN over more cycles
PFS vs Onpro®
Adherence to G-CSF therapy was HIGHER WITH NEULASTA® ONPRO® than with the prefilled syringe
Adherence is defined as proportion of patients receiving treatment according to Clinical Practice Guidelines5
In this analysis, adherence was based on a comparative analysis of Neulasta® doses administered by PFS versus Neulasta® Onpro ® that was conducted using data from OSCER on 389,000 oncology patients who were seen in 2016. Percentage of dose administered was calculated by taking the sum of patients’ chemotherapy cycles with Neulasta ® and dividing by the sum of their total chemotherapy cycles. Both arms were assumed to have received the treatment as prescribed4

Generally events resolved after dose reduction or discontinuation of Neulasta®
If suspected, evaluate for cause and if cause is likely, consider dose-reduction or interruption of Neulasta®
Increased white blood cell counts of 100 x 109/L have been observed
Monitoring CBCs is recommended
Capillary Leak Syndrome (CLS)
CLS has been reported after G-CSF administration, including Neulasta®
Characterized by hypotension, hypoalbuminemia, edema, and hemoconcentration
Episodes vary in frequency, severity, and may be life-threatening if treatment is delayed
Patients with symptoms should be closely monitored and receive standard symptomatic treatment, which may include intensive care
Potential for Tumor Growth Stimulatory Effects on Malignant Cells
G-CSF receptor has been found on tumor cell lines
The possibility that pegfilgrastim acts as a growth factor for any tumor type, including myeloid malignancies and myelodysplasia, cannot be excluded
Potential Device Failures
Missed or partial doses have been reported in patients receiving pegfilgrastim via the on-body injector (OBI) due to the device not performing as intended
In the event of a missed or partial dose, patients may be at increased risk of events such as neutropenia, febrile neutropenia and/or infection than if the dose had been correctly delivered
Instruct patients to notify their healthcare professional immediately in order to determine the need for a replacement dose if they suspect that the device may not have performed as intended
Aortitis has been reported in patients receiving Neulasta®. It may occur as early as the first week after start of therapy
Manifestations may include generalized signs and symptoms such as fever, abdominal pain, malaise, back pain, and increased inflammatory markers (e.g., c-reactive protein and white blood cell count)
Consider aortitis in patients who develop these signs and symptoms without known etiology. Discontinue Neulasta® if aortitis is suspected
Nuclear Imaging
Increased hematopoietic 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 interpreting bone imaging results
Most common adverse reactions
Bone pain
Pain in extremity

Special instructions for the on-body injector (OBI) for Neulasta®
A healthcare provider must fill the on-body injector (OBI) with Neulasta® using the co-packaged prefilled syringe and then apply the OBI 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 OBI. Approximately 27 hours after the OBI is applied to the patient's skin, Neulasta® will be delivered over approximately 45 minutes. A healthcare provider may initiate administration with the OBI on the same day as the administration of cytotoxic chemotherapy, as long as the OBI delivers Neulasta® no less than 24 hours after the administration of cytotoxic chemotherapy.
The prefilled syringe co-packaged in the Neulasta® Onpro® kit contains additional solution to compensate for liquid loss during delivery through the OBI. If this syringe is used for manual subcutaneous injection, the patient will receive an overdose. If the prefilled syringe for manual use is used with the OBI, the patient may receive less than the recommended dose.
Do not use the OBI to deliver any other drug product except the Neulasta® prefilled syringe co-packaged with the OBI. Use of the OBI has not been studied in pediatric patients.
The OBI should be applied to intact, non-irritated skin on the arm or abdomen.
A missed dose could occur due to an OBI failure or leakage. Instruct patients using the OBI to notify their healthcare professional immediately in order to determine the need for a replacement dose of pegfilgrastim if they suspect that the device may not have performed as intended. If the patient misses a dose, a new dose should be administered by single prefilled syringe for manual use as soon as possible after detection.
Review the Patient Information and Patient Instructions for Use with the patient and provide the instructions to the patient.
Refer to the Healthcare Provider Instructions for Use for the OBI for full administration information.
For any OBI problems, call Amgen at 1-800-772-6436 or 1-844-MYNEULASTA (1-844-696-3852).
