How Your Choice of G-CSF Delivery Method Matters
In the pivotal trial, next-day Neulasta® (pegfilgrastim) reduced the incidence of febrile neutropenia (FN) and FN-related hospitalizations when used every cycle, at the right time3,*

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%]).
FN = temperature ≥ 38.2°C and absolute neutrophil count (ANC) < 0.5 x 109/L.
Q3W = once every 3 weeks, IV = intravenous.

This was an observational study and no formal statistical testing was performed. Descriptive statistics are available.
Adjusted for baseline clinical and demographic differences between the groups, eg, degree of FN risk of chemotherapy regimen.
The primary endpoint was the overall incidence of FN over four cycles of chemotherapy, measured as ANC < 1000 × 106/L and one of the following occurring within 24 hours of decreased ANC: Temperature > 38°C, use of specific oral antibiotics (eg, ciprofloxacin, levofloxacin, moxifloxacin, amoxicillin-clavulanate), or use of IV antibiotics.5
CI = confidence interval.
A lower frequency of FN was shown by using Onpro® every cycle, at the right time
Percent of patients receiving pegfilgrastim PFS (innovator or biosimilar) on the day after chemotherapy, for all cycles in which pegfilgrastim PFS was administered.
Note: For any given patient, physicians generally chose the same FN-prevention therapy over time. However, a small percentage of patients received different therapies in different cycles. To facilitate comparison, the Onpro® group was comprised of patients who received Onpro® in every cycle. The comparator group was comprised of patients in the other physician-choice group who received pegfilgrastim PFS (innovator or biosimilar) at least once, and measured patient compliance for only those cycles in which pegfilgrastim PFS was administered.
PFS = prefilled syringe.
9 out of 10 patients who received Neulasta® Onpro® in the first cycle received Onpro® in every cycle

Study Design4,5
- Prospective, observational US study to describe frequency of FN, adherence, and compliance among patients receiving myelosuppressive chemotherapy for breast, lung, prostate, or NHL malignancies
- The study enrolled patients from November 2018 to April 2020
- The primary analysis included 2575 patients who completed up to four chemotherapy cycles
-
Investigators decided on the method of FN-prophylaxis. Patients were grouped into either the Neulasta® Onpro® group or other FN-prophylaxis group based on FN-prophylaxis method received in the first cycle. In both groups, physicians could change the type of
G-CSF used in the following cycles (choice in first cycle was generally consistent across subsequent cycles)
- Other FN-prophylaxis options included Neulasta® PFS or pegfilgrastim biosimilar PFS (61.7%), daily short-acting filgrastim or filgrastim biosimilar (7.3%), or no G-CSF (30.9%)
-
Secondary endpoints included: 1) Patients who received G-CSF support for all chemotherapy cycles regardless of timing of G-CSF administration (persistence) and
2) Patients who received pegfilgrastim on the day after chemotherapy in every cycle in which pegfilgrastim was administered (compliance)
Study Limitations5
- It was not possible to evaluate FN risk among patients lost to follow-up after study enrollment
- Although the analysis of FN incidence controlled for known baseline differences between the groups, the lack of randomization means that the groups may have differed in ways that were not measured or recorded. The impact of such differences on the study findings is unknown
- The study enrollment closed prematurely due to COVID-19 and did not achieve target sample sizes

Study Design: Retrospective cohort study conducted at Geisinger Health System (Danville, PA), Henry Ford Health System (Detroit, MI), Kaiser Permanente Northwest (Portland, OR), and Reliant Medical Group (Worcester, MA), January 2009-December 2017 (for all sites except Geisinger, 2009-2014). Analysis included patients with breast cancer, colorectal cancer, lung cancer, or non-Hodgkin’s lymphoma, receiving chemotherapy regimens with high or intermediate risk of FN. Multivariable regression models were employed to estimate the relationship between the use of Neulasta® and RDI.
Dose intensity is defined as the delivered dose of chemotherapy per unit of time. Relative dose intensity (RDI) is expressed as a percentage, calculated as the delivered dose intensity divided by the standard dose intensity. A higher RDI is indicative of fewer dose reductions and delays. Patients with RDI ≥ 85% were considered to have maintained their dose. The 85% cut point is commonly reported in the literature.7
It was not possible to determine from the data whether patients received Onpro® or the prefilled syringe. However, of the 379 patients from these healthcare systems who received Neulasta® in the first cycle, 97% (n = 368) received it on the day following chemotherapy, as recommended in the Neulasta® Prescribing Information. The Neulasta® group in this analysis was limited to next-day patients.
RDI ≥ 85%.
Course-level analysis. All cycles included. The analysis categorized patients as next-day Neulasta® users vs non-users of G-CSF based on the first cycle of chemotherapy only. However, for patients who received next-day Neulasta® in cycle 1, subsequent Neulasta® use was: 87% in cycle 2, 86% in cycle 3, and 78% in cycle 4. For patients who did not receive any G-CSF in cycle 1, no G-CSF use was 81% in cycle 2, 79% in cycle 3, and 79% in cycle 4.
Adjusted odds ratio controlling for clinical and demographic characteristics, including but not limited to age, metastasis (yes/no), and FN risk of chemotherapy regimen.
What Patients and Nurses Say
Neulasta® Onpro® is patient- and nurse-chosen protection*
95%
95% of patients and nurses would choose Neulasta® Onpro® again8,9,†,‡
- 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-CSF9,§
- 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-CSF9
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®.3

Incomplete doses have been reported with Neulasta® Onpro® due to device not performing as intended. This may increase risk of neutropenia, febrile neutropenia, and/or infection.
