Study summary

This is a phase I, single-center, randomized, open-label, single-dose, 2-way, 2-period, crossover study to evaluate the effect of food on the pharmacokinetics (PK) of vamifeport prolonged-release (PR) formulation in healthy adult participants. Participants will be randomly allocated to one of two treatment sequences.

Study arms

  • Experimental
    Sequence 1: Vamifeport Fasted then Fed

    In sequence 1, eligible participants assigned to sequence 1 will receive a single vamifeport dose on an empty stomach on Day 1 (fasted condition), undergo a washout period, and then receive a single vamifeport dose after a standardized high-fat meal (fed condition) on Day 6.

    Drug: Vamifeport (PR formulation)

  • Experimental
    Sequence 2: Vamifeport Fed then Fasted

    In sequence 2, eligible participants assigned to sequence 2 will receive a single vamifeport dose after a standardized high-fat meal on Day 1 (fed condition), undergo a washout period, and then receive a single vamifeport dose on an empty stomach (fasted condition) on Day 6.

    Drug: Vamifeport (PR formulation)

Interventions

  • DrugVamifeport (PR formulation)

    Vamifeport will be administered orally

What researchers measure

Primary outcomes

  1. Area under the plasma concentration-time curve from time zero to the time of the last quantifiable concentration (AUC0-last) of vamifeport

    Time frame: 0-96 hours after dose

  2. AUC from time zero extrapolated to infinity (AUC0-inf) of vamifeport

    Time frame: 0-96 hours after dose

  3. Maximum observed plasma concentration (Cmax) of vamifeport

    Time frame: 0-96 hours after dose

Secondary outcomes

  1. Number of participants with treatment emergent adverse events (TEAEs) overall, by severity, seriousness, and relationship to vamifeport

    Time frame: Up to Day 13 (+/- 2 days)

  2. Percentage of participants with TEAEs overall, by severity, seriousness, and relationship to vamifeport

    Time frame: Up to Day 13 (+/- 2 days)

  3. Number of participants with clinically significant changes from baseline in clinical laboratory safety tests (biochemistry, hematology, and urinalysis), 12-lead electrocardiogram (ECG), and vital signs, reported as TEAEs

    Time frame: Up to Day 13 (+/- 2 days)

  4. Percentage of participants with clinically significant changes from baseline in clinical laboratory safety tests (biochemistry, hematology, and urinalysis), 12-lead ECG, and vital signs, reported as TEAEs

    Time frame: Up to Day 13 (+/- 2 days)

  5. Time of the maximum observed plasma concentration (Tmax) of vamifeport

    Time frame: 0-96 hours after dose

  6. Apparent terminal disposition phase plasma half life (t1/2) of vamifeport

    Time frame: 0-96 hours after dose

  7. Apparent terminal disposition rate constant (λz) of vamifeport

    Time frame: 0-96 hours after dose

  8. Apparent total clearance (CL/F) of vamifeport

    Time frame: 0-96 hours after dose

  9. Apparent volume of distribution (V/F) of vamifeport

    Time frame: 0-96 hours after dose

  10. Percentage of AUC due to extrapolation from the last quantifiable concentration to infinity (%AUCextrap) of vamifeport

    Time frame: 0-96 hours after dose

  11. Time of the last quantifiable concentration (Tlast) of vamifeport
