NCT02898779

Brief Summary

To investigate the comparative tolerability, metabolism and pharmacokinetics of individual enantiomers of PQ in healthy human volunteers. The specific aim is the comparative evaluation of the metabolism, pharmacokinetic behavior, and tolerability of the isomers of PQ (RPQ and SPQ and the racemic mixture RSPQ) in normal healthy human volunteers.

Outcome Measures

Primary Outcomes (1)

  • Primary outcome: Plasma concentration of parent primaquine and carboyprimaquine following a single dose treatment with primaquine (racemate or enantiomers) not to exceed 45 mg

    This study would provide information on differential pharmacokinetics and metabolism of enantiomers of primaquine in normal human volunteers

    between 0-24 Hours

Secondary Outcomes (7)

  • Area Under Curve (AUC) for primaquine up to 24 hours after the primaquine administration

    between 0-24 hours

  • Maximum concentration (Cmax) for primaquine up to 24 hours after the primaquine administration

    between 0-24 hours

  • Area Under Curve (AUC) for carboxyprimaquine, the major plasma metabolite of primaquine, up to 24 hours after primaquine administration

    between 0-24 hours

  • Maximum concentration of carboxyprimaquine, the major plasma metabolite of primaquine, up to 24 hours after primaquine administration

    between 0-24 hours

  • Maximum concentration of selected metabolites primaquine (other than carboxyprimaquine) up to 24 hours after primaquine administration

    between 0-24 hours

  • +2 more secondary outcomes

Study Arms (2)

Cohort 1 ( Primaquine Low Dose)

EXPERIMENTAL

Interventions: Primaquine, R-Primaquine, S-Primaquine, SR Primaquine A single center, prospective, cross-over, randomized phase 1 trial. Thirty-six participants, enrolled into a two cohort pharmacokinetic study evaluating two dose levels of primaquine isomers. Cohort 1 (Low Dose Level)- single dose of 15 mg of S-Primaquine and 15 mg of R-Primaquine compared to 30 mg RS-Primaquine over 24 hours. Participants will cross-over after a one week wash-out period.

Drug: Primaquine, R-Primaquine, S-Primaquine, SR Primaquine

Cohort 2 (Primaquine High Dose)

EXPERIMENTAL

Interventions: Primaquine, R-Primaquine, S-Primaquine, SR Primaquine A single center, prospective, cross-over, randomized phase 1 trial. Thirty-six participants, enrolled into a two cohort pharmacokinetic study evaluating two dose levels of primaquine isomers. Cohort 2 (High Dose Level)-single dose of 22.5 mg of S-Primaquine and 22.5 mg of R-Primaquine compared to 45 mg RS-Primaquine over 24 hours. Participants will cross-over among the treatment arms following a one week wash-out period between each.

Drug: Primaquine, R-Primaquine, S-Primaquine, SR Primaquine

Interventions

Cohort 1: Eighteen individuals (6 per group) Cohort 2: Eighteen individuals (6 per group) Group 1-15 mg of S-Primaquine followed by one-week washout, 15 mg of R-Primaquine followed by one week washout, and 30 mg of RS-Primaquine. Group 2- 15 mg of R-Primaquine followed by one-week washout, 30 mg of RSPQ followed by one week washout, and 15 mg of SPQ. Group 3- 30 mg of RS-Primaquine followed by one week washout,15 mg of SPQ followed by a one week washout, and 15 mg of RPQ.
