Product Profile:

Pegfilgrastim-apgf (Nyvepria)

Drug Category: Granulocyte colony–stimulating factor

Target Indications: Reduce the incidence of infection in patients with nonmyeloid malignancies receiving myelosuppressive anti‑cancer drugs associated with a clinically significant incidence of febrile neutropenia.

Manufactured and marketed by Pfizer

Biosimilar Drug Profile: Nyvepria (HSP-130/PF-06881854) is a biosimilar version of pegfilgrastim (reference product, Neulasta by Amgen) that is manufactured by Pfizer. It is a legacy product of Pfizer’s acquisition of Hospira in 2015. A biologic license application for approval via the 351(k) biosimilar pathway was submitted to the Food and Drug Administration (FDA) in the third quarter of 2019, with final approval given June 11, 2020. This approval was supported by two phase 1 studies in addition to comprehensive analytical and characterization research. Nyvepria is the fourth pegfilgrastim biosimilar to obtain approval, and it was approved for all of the reference product’s indications. Nyvepria has not yet been launched in the United States.

About the Manufacturer

Pfizer entered the biosimilar market through two avenues: (1) its acquisition of Hospira and (2) its own internal pipeline development. Pfizer was established in 1849, and it is headquartered in New York City. It has a considerable portfolio of biosimilar products approved by the FDA and in various stages of filing. In addition to Nyvepria, its approved biosimilars include Inflectra, the first biosimilar version of Remicade; Ixifi, another version of Remicade that will be sold overseas only; Trazimera, a biosimilar trastuzumab; Retacrit, a biosimilar epoetin that was approved in May 2018; Ruxience, a biosimilar rituximab that was approved in July 2018; Zirabev, a biosimilar bevacizumab approved in July 2019; and Nevistym, a biosimilar version of filgrastim that is also marketed. Pfizer’s biosimilar pipeline consists of a biosimilar adalimumab in phase 3 trials.

Competitor Products and Manufacturer Analysis

Nyvepria is the fourth pegfilgrastim biosimilar to be approved by the FDA. Pfizer indicated that it would be launched at some point in 2020, without further specification. According to a Bernstein analysis, Amgen’s Neulasta OnPro® holds the dominant marketshare, at 58% in April 2020, followed by Coherus Bioscience’s Udenyca®, at 20%. The first biosimilar approved, Mylan/Bioon’s Fulphila® trails with approximately 6%, and Sandoz’s Ziextenzo® gained slightly less than 1% of the marketshare since its November 2019 launch. The original syringe and vial form of Neulasta continues to lose its share of the market, capturing 15% at the time of Bernstein analysis.

Clinical Trials of Nyvepria

Published Trial Results

In addition to its supporting data on physiochemical and structural characteristics, Pfizer’s biologic licensing application was supported by two phase 1 clinical data only (in healthy subjects, not patients). A third phase 1/2 open-label trial was conducted, but it was not a comparative study with the reference agent, and will not be described here.

The objectives of these phase 1 trials in healthy volunteers, were to compare the pharmacokinetics (PK), pharmacodynamics (PD), and safety of HSP-130/PF-06881894 with the reference pegfilgrastim product US and EU-licensed Neulasta (manufactured by Amgen).

The first phase 1 trial was an open-label, randomized, crossover study comprising 153 healthy subjects. Each subject (18–65 yr) was administered a single 6-mg dose of the biosimilar or reference product. The researchers’ primary endpoints were fourfold: (1) the relationship between the absolute neutrophil count (ANC) and time postdose (measured by the area under the curve), (2) the maximum observed ANC, (3) area under the serum pegfilgrastim concentration–time curve, and (4) maximum serum pegfilgrastim levels. The objective of the study was to prove the biosimilar yielded outcomes that were within the predefined 90% confidence interval acceptance limits of the reference agent.

The researchers found that the pharmacodynamics and pharmacokinetic parameters assessed were within the accepted predefined limits, concluding that PF-06881894 elicited similar results to the reference agent.

The second phase 1 trial was an open-label, randomized, parallel-group, study (420 subjects total) that analyzed the safety and immunogenicity of several 6-mg doses of the biosimilar compared with that of US-licensed Neulasta. For this investigation, the main endpoint was the percentage of subjects with the presence of anti-pegfilgrastim antibodies at any time after dosing. Based on the results of this trial, the researchers concluded that the biosimilar did not produce any clinically meaningful safety outcomes compared with Neulasta and was determined to be noninferior.
