  Purpose

Study Design

  • Randomized, double-blind, placebo-controlled, escalating single-dose design.
  • Six ascending dose cohorts
  • In each cohorts, subjects will be randomized to receive a single dose of HM10460A, placebo (negative control), or Neulasta® (positive control).
  • Primary Objective
  • to assess the safety and tolerability of single escalating subcutaneous doses of HM10460A in healthy adult Japanese and Caucasian subjects.

Condition Intervention Phase
Healthy Drug: HM10460A or placebo or Neulasta Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Treatment
Official Title: A Randomized, Double-Blind, Placebo- and Active-Controlled, Escalating Single-Dose Study to Evaluate the Safety, Tolerability, and PK of HM10460A (HNK460) When Administered Subcutaneously to Healthy Adult Japanese and Caucasian Subjects.

Further study details as provided by Hanmi Pharmaceutical Company Limited:

Primary Outcome Measures:
  • Safety data, including physical examinations (to include injection site reactions and splenic evaluations), laboratory evaluations, ECGs, vital signs assessments, and adverse effects (AEs). [ Time Frame: Time points where appropriate. ]
  • Samples for immunogenicity [ Time Frame: Days -1, 15, 22, and 42. ]

Secondary Outcome Measures:
  • PK parameters measured from Serum and Urine samples. [ Time Frame: Serum samples: pre-dose, 0.25, 0.5, 0.75, 1, 2, 3, 4, 6, 8, 12, 16, 24, 36, 48 hrs, Days 4, 5, 6, 7, 11, 15, and 22. / Urine Samples: 0 - 6, 6 - 12, 12 - 24, 24 - 36, and 36 - 48 hours post-dose. ]
  • Calculation of ANC and CD34+ cell counts. [ Time Frame: pre-dose, 24 and 48 hours post-dose, Days 4, 5, 6, 7, 11, 15, and 22. ]

Detailed Description:

Secondary objectives:

  • to assess the pharmacokinetics (PK) of a single subcutaneous dose of HM10460A.
  • to compare the PK of HM10460A in Japanese and Caucasian subjects.
  • to assess the relationship between the serum concentration of HM10460A and absolute neutrophil count (ANC).
  • to assess the relationship between the serum concentration of HM10460A and CD34+ cell counts in the blood.
  • To assess the immunogenicity potential of HM10460A by measuring binding antibodies (bAb) and neutralizing antibodies (nAb) to HM10460A and native G-CSF following a single subcutaneous dose of HM10460A.
