Clinical Trial Summary

This is a multi-center, randomized, Phase 2/3 study to evaluate the safety and efficacy of pyronaridine-artesunate in participants with corona virus disease 2019 (COVID-19). Pyronaridine-artesunate has been approved in Europe, Asia and Africa under brand name of Pyramax® or Artecom® as a treatment for malaria. The study will be conducted in two stages: open-label (Stage 1) and double-blind (Stage 2).

Up to approximately 402 participants (20 participants in Stage 1 and 382 participants in Stage 2) are planned to be enrolled in the study and will be randomized to receive either Artecom® or matching placebo at a ratio of 1:1 in Stage 2. The dose of Artecom® will be determined by the participant's body weight, according to previously established guidelines.

An independent Drug Safety Monitoring Board (DSMB) will be established to review the safety at regular intervals during the conduct of the trial. The DSMB will be subject to a Charter and will review after 20 participants have been recruited, and thereafter when 191 participants have been recruited.

Ad-hoc DSMB meetings may be held at any time during the study if there are any major safety concerns. A final DSMB will be conducted when all participants have been recruited in the trial.

Description:

In Stage 1, the trial will be conducted in 20 participants for 28 days in a single arm, open-label design. Artecom® will be administered orally once a day for 3 consecutive days. All subjects will be evaluated for efficacy and safety for 28 days.

After the completion of the final participant in Stage 1, the DSMB will review the safety data from Stage 1 and determine whether to proceed to Stage 2.

In Stage 2, a total of 382 participants will be enrolled and randomized in a double blinded manner to receive either Artecom® or placebo (1:1 ratio) orally once a day for 3 consecutive days. All subjects will be evaluated for efficacy and safety for 28 days.

A second DSMB meeting and review of all available blinded safety data will occur after 191 participants have completed Day 28. A final DSMB meeting will be held after the completion of a study assessment by the last participant.

7. Participants with severe hepatic impairment (Alanine aminotransferase or Aspartate aminotransferase =5x upper limit of normal) or have symptoms of abdominal pain or vomiting associated with Jaundice or Child-Pugh Stage B or C

8. Viral infections other than COVID-19 that requires administration of other antiviral agents (for example but not limited to human immunodeficiency virus, hepatitis B virus, hepatitis C virus)

9. Participants requiring mechanical ventilation (e.g. non-invasive ventilation, invasive mechanical ventilation, extracorporeal membrane oxygenation etc.). However, those who can be given oral administration are not exdluded.

10. Participants with chronic underlying diseases (such as uncontrolled diabetes, chronic kidney disease, chronic liver disease, chronic lung disease [including asthma, chronic obstructive pulmonary disease and tuberculosis], chronic cardiovascular disease, blood cancer, cancer participants with anti-cancer treatment, participants taking immunosuppressants, etc.), participants with high obesity (BMI > 40), dialysis participants, transplant participants whom are inadequate to participate in clinical trials based on the Investigator's discretion.

11. Pregnant or lactating at Screening or planning to become pregnant (self or partner) at any time during the study, including the follow-up period.

12. Participants who participated in another clinical trial / medical device clinical trial within 28 days from the date of signing the consent and received drug / operated medical device for clinical trial.

13. Participants who the Investigator has deemed inappropriate for inclusion in this study for any other reason.

14. Prior or ongoing medical conditions, medical history, physical findings, or laboratory abnormality that, in the Investigator's (or delegate's) opinion, could adversely affect the safety of the participant.
