7. History of malignancy within 5 years before the baseline visit (with certain exceptions)
8. Planned surgical procedure during the length of the study
9. High risk of parasite infection
10. Any other medical or psychological condition that in the opinion of the investigator or the sponsor's medical monitor, would place the participants at risk, interfere with participation in the study or interfere with interpretation of study results
