Neulasta® Onpro® is patient- and nurse-chosen protection*

95% icon

of patients and nurses would choose Neulasta® Onpro® again5,6,†,‡

Not having to return to the doctor’s office the day after chemotherapy just for an injection was the most important factor for patients when choosing a G-CSF5,§

Patients also valued how much experience their doctor has with the G-CSF they would receive and being informed by the doctor or nurse of all available ways to receive the G-CSF5

*In a key study of 928 patients with breast cancer, when given once every chemotherapy cycle, 17% of patients got infections when not treated with Neulasta®—while only 1% of patients got infections when treated with Neulasta®.7

†2016 data from interviews with oncology patients who have had experience with Neulasta® (N = 227, PFS [n = 150], Neulasta® Onpro® [n = 77]).

Patients who had received Neulasta® via Neulasta® Onpro® were asked to answer the question: Based on your personal experience getting your Neulasta® with Neulasta® Onpro®, if your doctor said you needed to use Neulasta® again in the future, would you request getting it with Neulasta® Onpro® again?5

‡Data from interviews with oncology nurses (N = 250) conducted in October 2016. Respondents were asked if they agree with this statement: Based on my Neulasta® Onpro® experience, when my patients are appropriate for Neulasta® (PFS or Neulasta® Onpro®), I would choose Neulasta® Onpro®.6

§November 2016 data from interviews with oncology patients who have had experience with Neulasta® (N = 227, PFS [n = 150], Neulasta® Onpro® [n = 77]). Patients were asked a multiple-choice selection prompt: If your doctor felt you should receive a G‑CSF medication, please select the 3 most important factors to you (other than safety and how well it works) when considering G‑CSF care to boost your white blood cell count after chemotherapy. Patients then completed a follow-up prompt: Of the 3 most important factors you selected, we would like to know which is the most important. Please rank these from most important (1) to least important (3).5

Shaquita's Story

"The best part of using Neulasta® Onpro® is that I get the medication I need, while also protecting myself from other risks—at the hospital, doctor's office, etc.—that would cause a delay in my chemotherapy."

Bill's Story

"Neulasta® Onpro® has allowed me to keep up with my chemo plan because I've not had to worry about my white blood cell count. It has stayed high enough where I've been able to keep going."

Neulasta® Onpro® is designed to facilitate next-day G-CSF delivery.*

  • Evaluate patients who develop a fever and lung infiltrates or respiratory distress after receiving Neulasta®
  • Discontinue Neulasta® in patients with ARDS

Serious Allergic Reactions

  • Serious allergic reactions, including anaphylaxis can occur in patients receiving Neulasta®
  • Majority of events occurred upon initial exposure and can recur within days after discontinuation of initial anti-allergic treatment
  • Permanently discontinue Neulasta® in patients with serious allergic reactions

Allergies to Acrylics

  • On-body injector (OBI) for Neulasta® uses acrylic adhesives
  • Patients who are allergic to acrylic adhesives may have a significant reaction

Use in Patients With Sickle Cell Disorders

  • In patients with sickle cell trait or disease, severe and sometimes fatal sickle cell crises can occur in patients receiving Neulasta®
  • Discontinue Neulasta® if sickle cell crisis occurs

Glomerulonephritis

  • Has occurred in patients receiving Neulasta®
  • Diagnoses based on azotemia, hematuria, proteinuria, and renal biopsy
  • 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®

Leukocytosis

  • Increased white blood cell counts of 100 x 109/L have been observed
  • Monitoring of complete blood count (CBC) during pegfilgrastim therapy is recommended

Thrombocytopenia

  • Thrombocytopenia has been reported in patients receiving pegfilgrastim. Monitor platelet counts

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, diseases for which Neulasta® is not approved, cannot be excluded

Myelodysplastic Syndrome (MDS) and Acute Myeloid Leukemia (AML) in Patients With Breast and Lung Cancer

Neulasta® Injection: 6 mg/0.6 mL in a single-dose prefilled syringe for manual use only.

Neulasta® Injection: 6 mg/0.6 mL in a single-dose prefilled syringe co-packaged with the on-body injector (OBI) for Neulasta® (Neulasta® Onpro® kit).

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 1-800-772-6436 or 1-844-MYNEULASTA (1-844-696-3852). 1-844-MYNEULASTA (1-844-696-3852).
