December 12, 2023 updated by: Medicines for Malaria Venture

Phase 1, Open-label, Cross-over Study to Investigate the Relative Bioavailability of Pyramax (Pyronaridine-artesunate) in Tablet and Granule Formulations, in Healthy Volunteers

The primary objective of this study is to compare the bioavailability of two formulations (tablets and granules for dispersion) of the antimalarial drug pyronaridine-artesunate [3:1] (Pyramax, PA) in healthy adults. The secondary objective is to compare the safety of the two PA formulations and liver function test changes following the first and second administrations.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a Phase I, single centre, open-label, randomised, two-way cross-over study in healthy volunteers to compare the bioavailability of two formulations of pyronaridine-artesunate, in tablet and in granule formulation. The study population will include 60 healthy volunteers, comprising male and female adults aged 20 to 45 years inclusive.

The volunteers will be randomised equally on Day -1 to one of two sequences: Sequence 1 (tablets in Period 1, granules in Period 2), or Sequence 2 (granules in Period 1, tablets in Period 2). The periods will be separated by a 60-day wash-out period. Each of the two pyronaridine-artesunate formulations will be administered as a single dose of either 180:60 mg pyronaridine-artesunate tablets (3 tablets) or 60:20 mg pyronaridine-artesunate granules (9 sachets). The total dose of each formulation administered is 540:180 mg pyronaridine-artesunate.

The study duration from the first study drug administration (Day 1) through to the last follow-up will be approximately 103 days. Screening is to be performed within 28 days before Day 1. Adverse events will be monitored throughout the study (and to resolution if necessary) to assess the general safety and tolerability of the treatments.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
