About this study
Official title: A Single Center, Prospective Study to Compare the Quality and Quantity of the Cellular Content of M-PRP Harvested After Peripheral Mobilization of Progenitor Cells Using Filgrastim Versus Pegfilgrastim
The goal of this prospective, observational study is to compare the quality and quantity of the cellular content of platelet-rich plasma harvested after administering one of two cell-stimulating proteins, filgrastim and pegfilgrastim. The main question it aims to answer is:
- Will participants have a similar cellular content when comparing a 4-day filgrastim treatment to a one-day pegfilgrastim treatment?
Read more
Participants will have the following intervention administered:
- 130mL of blood will be drawn on the first visit after consent and in followup visits after administering treatment (4 days for filgrastim, 7 days for pegfilgrastim)
- Half of all participants will receive filgrastim first, followed by pegfilgrastim 8 weeks after filgrastim treatment concludes. The other half will receive the treatments in reverse order
Researchers will compare the quality and quantity of cell content after each treatment administration as well as comparing differences in data dependent on which order treatment was given.
Read the detailed description
The proposed study is a prospective, randomized controlled, single-center laboratory study involving 10 healthy volunteers. Once the potential participant has cleared the screening, consented to the study procedures, completed the medical interview, and laboratory blood testing, the subject will undergo two serial mobilization events. The scheduling of the mobilization events will be varied across the 10 participants to counter sequencing effects of the mobilization events. 5 healthy donors will be administered standard filgrastim mobilization regimen of 10 mcg/kg per day for 4 days. This will be followed by a standard pegfilgrastim mobilization regimen consisting of one 6 mg injection separated by 8 weeks for 5 of the participants. The other 5 healthy donors will receive the reverse order of the pharmaceutical agent, first pegfilgrastim followed by filgrastim.
On the first day of the study, a first blood draw of 130 mL will be performed which will be used to create standard PRP for laboratory testing and subjects will begin a filgrastim or pegfilgrastim dosage series. After the specified time (4 days for filgrastim and 7 days for pegfilgrastim), a second 130 mL of blood will be harvested and processed with the Arthrex Angel system to create M-PRP for laboratory testing. The standard PRP and M-PRP cellular content will be studied and quantified in vitro with cell counting, cell culturing and protein analysis. 8 weeks after the second blood harvest, the subjects will return for a third 130 mL of blood draw, followed by administration of a second mobilizing agent (pegfilgrastim or filgrastim). After the specified time (4 days for filgrastim and 7 days for pegfilgrastim), the patients will return for a fourth blood draw of 130mL. The sample will be processed with the Arthrex Angel system to create M-PRP for laboratory testing. The cellular content of the M-PRP product will be studied and quantified in vitro with cell counting, cell culturing and protein analysis. Thereafter, the cellular content of M-PRP product will be compared between filgrastim and pegfilgrastim mobilization agents.

| Study group | Role | What they receive |
|---|---|---|
| Filgrastim to Pegfilgrastim | Participants in this group will receive filgrastim treatment, followed by pegfilgrastim treatment at the 8-week mark. Receives: Drug: Filgrastim; Drug: Pegfilgrastim | |

What is being measured
The primary outcome is the main question the study is designed to answer.
Arthrex Angel System for PRP Concentration
Machine utilizing centrifugation and optics to precisely separate cell types using buffy coat method. . All cells have a density range and non-uniformly after centrifugation. Arthrex Angel system has the unique ability to isolate specific cells using inherent properties of cells that absorb differing wavelengths of light. The settings on the system can be controlled to adjust the proportion of cells versus plasma. Increasing the setting from 7% to 15%, the Angel system isolates more cells from a deeper portion of the buffy coat, which results in capturing more HPCs per volume.
Measured: at time of enrollment

The goal of this prospective, observational study is to compare the quality and quantity of the cellular content of platelet-rich plasma harvested after administering one of two cell-stimulating proteins, filgrastim and pegfilgrastim. The main question it aims to answer is:
- Will participants have a similar cellular content when comparing a 4-day filgrastim treatment to a one-day pegfilgrastim treatment?
Participants will have the following intervention administered:
- 130mL of blood will be drawn on the first visit after consent and in followup visits after administering treatment (4 days for filgrastim, 7 days for pegfilgrastim)
- Half of all participants will receive filgrastim first, followed by pegfilgrastim 8 weeks after filgrastim treatment concludes. The other half will receive the treatments in reverse order
Researchers will compare the quality and quantity of cell content after each treatment administration as well as comparing differences in data dependent on which order treatment was given.
