Intervention model description: This is a single blind parallel comparative immunogenicity study
Primary purpose: TREATMENT

Brief summary: This study will compare treatment emergent incidence rate of ADA between TPI-120 and US licensed Neulasta in normal healthy adult subjects

Detailed description: Healthy subjects have been selected as the study population for this comparative study because this population is more homogenous with respect to immune response and offers significant advantages with regards to recruitment and logistical aspects. This study will comprise of two cycles with each cycles will have a single dose of PEG FILGRASTIM administration to all study subjects as per the randomization schedule. Subjects will be confined from at least 10 hours prior to dosing, at the time indicated by the CRU, until 36 hours post-dose on day 2 in each Cycle. Dosing in each Cycle are separated by 21 days.

Subjects will return for all subsequent blood draws and ADA assessments, as indicated in The Schedule of Event

6. Hereditary fructose intolerance.
7. Females with positive pregnancy tests at screening or check-in.
8. Any reason which, in the opinion of the Investigator, would prevent the subject from participating in the study or completing follow-up activities.
9. Clinically significant ECG or vital signs abnormalities at screening.
10. History of significant alcohol abuse within one year prior to initial dosing or regular use of alcohol (more than 14 units of alcohol per week) within six months prior to initial dosing.
11. History of drug abuse or use of illicit/illegal drugs within 1 year prior to initial dosing.
12. No medications are permitted during the study. Exceptions are:
