Study Comparing TPI-120 and Neulasta Administered Through Subcutaneous Route in Healthy Adult Subjects

Phase 1

Completed

• Conditions: Healthy Volunteers
• Interventions: Drug: PEG-rhG-CSF; Drug: Neulasta (PEG-rhG-CSF)

• Registration Number: NCT03206229
• Lead Sponsor: Adello Biologics, LLC

Brief Summary

This is a single or up to 2 centers, double-blind, randomized, single-dose, two-way, crossover study comparing the Test (T) and Reference (R) products following subcutaneous administration. Subjects will be randomly assigned to one of two treatments sequences (TR or RT).

All subjects will be dosed at the CRO's designated clinical site(s) and the same protocol requirements and procedures will be followed within each group.

Detailed Description

The current study design was prepared to assess and compare the PK, PD, safety, tolerability of the Adello biosimilar candidate, TPI-120 and the US-licensed reference product, Neulasta® after administering a single subcutaneous 2 mg dose in healthy adult subjects in a crossover design. The primary PK parameters are AUC0-t, AUC0-inf, and Cmax, and the primary PD parameters are baseline-corrected AUEC0-t and Emax for ANC.

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.
