To assess the efficacy of USV Pegfilgrastim compared to Neulasta® with respect to the mean duration of severe neutropenia (DSN) defined as the mean number of days with Grade 4 neutropenia [absolute neutrophil count (ANC) less than 0.5 × 109/L], during Cycle 1 of the chemotherapy treatment.
|
||

Recruitment
|
||||||||||||||||||||||
Recruitment details |
Total 254 subjects were enrolled (172 in USV Pegfilgrastim and 82 in Neulasta arm). Subjects were randomised in a ratio of 2:1 to receive either USV Pegfilgrastim or EU-licensed Neulasta® (active control treatment) in a country stratified manner. A total of 6 subjects, discontinued the study before receipt of first dose of IMP. | |||||||||||||||||||||

Blinding implementation details |
This was assessor blinded trial. The allocated treatment was disclosed only to the unblinded study staff. There were separate blinded and unblinded study teams in each study site. The unblinded team member(s) were responsible for the receipt, accountability, preparation, and administration of the study treatment (pegfilgrastim treatment). The assessor(s) –the prinprincipal investigator and other co-investigators participating in the subject assessments were blinded to the treatment allocation.

Mean duration of severe neutropenia (Grade 4), defined as the number of days in which the subject had an ANC < 0.5 × 10^9/L during Cycle 1 of chemotherapy. | ||||||||||||
End point description |
The main efficacy endpoint was defined as the mean number of days of Grade 4 neutropenia (ANC below 0.5 x 10^9/L) during the first treatment cycle. The primary analysis of the duration of severe neutropenia in Cycle 1 consisted in testing equivalence of USV Pegfilgrastim and Neulasta®. The Least-square means (LSMeans) were estimated within a general linear model framework (using proc genmod in SAS), accounting for treatment arm, and applying a log link. LS Mean difference and 95% Confidence Interval (CI) between the two treatment arms was then back-transformed by exponentiation, resulting in a ratio of means and its 95% CI. Equivalence was concluded if the 95% CI of the ratio of means was entirely contained in the interval [0.65, 1.55].

Statistical analysis description |
The DSN in Cycle 1 was the primary endpoint for the comparative assessment of efficacy of USV Pegfilgrastim to Neulasta®. Severe neutropenia was defined as occurrence of ANC below 0.5 x 109/L. Equivalence was concluded if the 95% CI of the ratio of least-square means of DSN for the two treatment arms was entirely contained in the interval [0.65-1.55].
