Brief Summary
In this study, 4 dose groups are planned: Group 1 (0.22 mg, QD), Group 2 (0.22 mg, BID), Group 3 (0.44 mg, QD), and Group 4 (0.44 mg, BID). Ten healthy study participants will be enrolled in each dose group, and randomized to the investigational drug group or the placebo group in a 4:1 ratio (i.e., 8 study participants in the investigational drug group and 2 study participants in the placebo group). An appropriate gender ratio will be ensured within each dose group.

Outcome Measures
Primary Outcomes (1)
Safety and Tolerability Assessments
Assess safety and tolerability by evaluating treatment-emergent adverse events (TEAEs), serious adverse events (SAEs), and clinically significant abnormal findings from vital signs, physical examinations, 12-lead ECG (QTcF, PR interval, QRS duration, RR interval), and clinical laboratory tests.
From first study drug administration through Day 9

Study Arms (2)
Huperzine A Oral Solution
EXPERIMENTALHealthy participants receive multiple escalating oral doses of huperzine A oral solution in sequential cohorts. Advancement to subsequent dose cohorts is gated by review from the Safety Monitoring Committee (SMC) and Sponsor. Subjects within each cohort are randomized to study drug or placebo.
Placebo
PLACEBO COMPARATORHealthy participants receive matching placebo oral solution for multiple-dose administration. Randomization to placebo occurs within each sequential dose cohort, following SMC-gated cohort progression rules.
Interventions
Investigational huperzine A oral solution, administered orally in 4 sequential escalating multiple-dose cohorts to healthy adult participants.
Matching placebo, identical in appearance, taste and packaging to huperzine A oral solution, administered orally for multiple doses.
Eligibility Criteria
You may qualify if:
- Participants must provide written informed consent prior to the study, with full understanding of the study's objectives, procedures, and potential adverse reactions;
- Participants must be able to communicate effectively with the investigators and comply with the protocol requirements throughout the study.
- Healthy male or female, aged 18 to 55 years (inclusive);
- Body mass index (BMI) range: 19.0 to 26.0 kg/m2 \[BMI = body weight/height2 (kg/m2)\] (inclusive); male weight ≥50 kg, female weight ≥45 kg.
You may not qualify if:
- History of allergy to huperzine A or any drug component (pharmaceutical-grade sodium benzoate); history of allergies to two or more drugs, foods, etc.;
- History or suspected history of gastrointestinal bleeding, or conditions posing a risk of gastrointestinal bleeding (e.g., peptic ulcer, inflammatory bowel disease, diverticula, hemorrhoids, colonic polyps, etc.);
- Currently diagnosed with or suspected of having epilepsy, angina pectoris, bronchial asthma, mechanical intestinal obstruction, renal insufficiency, or urinary tract obstruction;
- Currently diagnosed with or suspected of having other serious diseases that, in the judgment of the investigator, make the individual unsuitable for participation in the study. These may include, but are not limited to, diseases related to the respiratory, circulatory, digestive, hematologic, endocrine, immune, integumentary, neuropsychiatric, or otorhinolaryngologic systems;
- Underwent major surgery within 180 days prior to the first dose or plans to undergo surgery during the study period;
- Participants with significant abnormalities in vital signs (normal reference ranges for vital signs (including critical values): body temperature (aural) 35.9 ℃ to 37.4 ℃, sitting systolic blood pressure 90 mmHg to 140 mmHg, sitting diastolic blood pressure 60 mmHg to 90 mmHg, sitting pulse 50 to 100 beats per minute, respiratory rate 12 to 20 breaths per minute), physical examination, electrocardiogram (QT interval corrected for heart rate using Fridericia's formula (QTcF) \>450 ms (males) or \>460 ms (females)), or laboratory test results, and judged by the investigator as unsuitable for participation in this study;
- History of hepatitis B, hepatitis C, HIV, or syphilis and/or those with one or more abnormal results in infectious disease screening (anti-HIV antibody, hepatitis B surface antigen, anti-hepatitis C virus antibody, anti-Treponema pallidum antibody) that are considered clinically significant by the investigator;
- Study participants who have experienced blood loss (excluding normal physiological blood loss in females) or donated ≥200 mL of blood or donated blood components (e.g., plasma, platelets, peripheral blood stem cells, etc.) within 90 days prior to the first dose;
- Individuals who used any drugs that alter hepatic enzyme activity within 30 days prior to the first dose (e.g., inducers such as barbiturates, carbamazepine, phenytoin sodium, dexamethasone; inhibitors such as selective serotonin reuptake inhibitors \[SSRIs\], ciprofloxacin, diltiazem, macrolides, metronidazole, ketoconazole, verapamil, fluoroquinolones, etc.), or non-steroidal anti-inflammatory drugs (NSAIDs) (e.g., aspirin, ibuprofen, naproxen, etc.);
- Use of any medications (including prescription drugs, over-the-counter drugs, and herbal medicines) and health supplements within 14 days prior to the first dose or within 5 half-lives of previous medication (whichever is longer), with the exception of topical medications and ophthalmic drops intended for local use.
- Study participants who have been vaccinated within 30 days prior to the first dose or plan to be vaccinated within 30 days after the end of the study;
- Participation in any clinical study within 90 days prior to the first dose;
- History of drug abuse within 5 years prior to screening, and/or use of illicit drugs within 90 days prior to screening, and/or history of drug dependence, including herbal medicine, or positive urine drug screening;
- Average daily smoking of more than 5 cigarettes within 90 days prior to screening, or unwillingness to avoid using any tobacco products within 48 h prior to the first dose and during hospitalization, or positive result in nicotine screening;
- Regular alcohol consumption within 180 days prior to screening, defined as consuming more than 14 units of alcohol per week (1 unit of alcohol = 360 mL of beer or 45 mL of spirits or 150 mL of wine), or unwillingness to stop alcohol intake within 48 h prior to the first dose and during hospitalization, or positive result in alcohol breath test;
