A Botanical Drug Extracted From Antrodia cinnamomea : A First-in-human Phase I Study in Healthy Volunteers.

LEAC-102 is an emerging drug extracted from the medicinal fungus Antrodia cinnamomea (AC), which is traditionally used to ameliorate fatigue and liver disorders arising from excessive alcohol consumption. AC has been used as a health product with an immunomodulatory function, but its anticancer effect has not been applied in clinical therapy as a drug. This first-in-human study examined the safety and tolerability of LEAC-102 as a new drug in healthy adults. This standard 3 + 3 dose-escalation study included 18 participants administered LEAC-102 at doses of 597.6, 1195.2, 1792.8, 2390.4, or 2988 mg/day for 1 month plus 7 days of safety follow-up. The maximum planned dose was 2988 mg. Dose-limiting toxicity (DLT) was monitored from the start of LEAC-102 administration up to the final visit. The dose of LEAC-102 was escalated to the subsequent cohort as long as there was no DLT in the previous cohort. Tolerability, clinical status, safety (by laboratory parameters), and adverse event occurrence were documented weekly during the treatment and 1 week after the conclusion of the treatment. All clinical biochemistry profiles were in the normal range, and no serious adverse effects were observed. The maximum tolerated dose of LEAC-102 was determined to be 2988 mg/day because one participant experienced urticaria. Additionally, our exploratory objectives revealed that LEAC-102 significantly elevated natural killer, natural killer T, and dendritic cells in a dose-dependent manner, activated effector T cells, and upregulated programmed cell death-1 expression. The outcomes suggested that LEAC-102 was well tolerated and safe in healthy adults and exhibited potential immunomodulatory function.
