This Phase I, single-arm, open-label, dose-escalation clinical study is designed to evaluate the safety and determine the maximum tolerated dose (MTD) of Orialpha (BD-C) in healthy adult volunteers. The study aims to:
* Determine the frequency and severity of treatment-related adverse events, adverse events leading to discontinuation, and serious adverse events (SAEs) within each cohort.
* Assess the effects of Orialpha on hematology and biochemistry parameters before dosing and after the final dose in each cohort.
Healthy volunteers who meet all eligibility criteria will receive the investigational product for 7 days. The first cohort will include 3 participants receiving the lowest dose (0.25 × the anticipated clinical dose). Following safety evaluation, subsequent cohorts will receive higher dose levels (0.5 ×, 1.0 ×, 1.5 ×, and 2.0 × the anticipated clinical dose) according to predefined dose-escalation rules.
