About this study
Official title: A Randomized, Double-blind, Parallel Study Comparing Pharmacokinetic (PK) and Pharmacodynamic (PD) Parameters of Pegcyte (Nanogen) and Reference Product Neulastim (Roche) for Chemotherapy-induced Neutropenia in Breast-cancer Patients
Breast cancer patients scheduled to receive myelosuppressive chemotherapy (AC regimen) will be enrolled in this study. Eligible patients receive single SC injection of pegcyte or neulastim 24 hours after administration of chemotherapy (Doxorubicin and Cyclophosphamide) in the first cycle (14 days each cycle). Blood samples are collected to determine the serum concentration of investigational drugs at specific time points in the first cycle. Absolute neutrophil count, CD34+ count, Cmax (maximum serum concentration), AUC0-t (area under the curve of the plasma concentration time) and Tmax (time required to reach Cmax) will be calculated from the serum concentration profile

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Pegfilgrastim in people with Breast Cancer, run by Nanogen Pharmaceutical Biotechnology Joint Stock Company at 1 site in Vietnam.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 Dec 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Vietnam. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Area under the curve from time 0 to the last time point (AUC0-t) for serum Pegfilgrastim (PEG-GCSF) (time frame: day 2 (0h, 3h, 6h, 12±4h), day 3 (24h), day 4 (48h), day 5 (72h), day 7 (120h), day 8 (144h), day 9 (168h), day 11 (216h), and day 14 (288h) of the first cycle). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Dec 2017.
