Subject must have a PANSS total score ≤ 80 and CGI-S score ≤ 4 at screening. The condition is stable from 1 month before signing informed consent to baseline.
Exclusion criteria
Healthy Subjects * Subjects have any clinically significant medical condition or chronic disease. * Subjects have used any of nonprescription drugs within 7 days or prescription drugs within 28 days prior to administration. * Subjects experienced a history of keratopathy, fundus disease, increased intraocular pressure, or angle-closure glaucoma. Subjects have any abnormal and clinically significant test for ophthalmic examination during screening. * Subjects with a history of orthostatic hypotension or syncope. * Subjects with condition that may interfere with the drug absorption, distribution, metabolism and excretion significantly. * Subjects had a history of surgery within 3 months prior to administration, or had not recovered, or have a surgical plan during the study. * Subjects have any clinically significant abnormal vital signs, laboratory values, and ECGs. * Subjects have a history of allergic diseases, or allergic to any substance contained in the formulation * Subjects have a positive test for HBsAg, HCV-Ab, HIV-Ab, or syphilis antibody. Subjects with Stable Schizophrenia * According to the DSM-5, there were other mental disorders except schizophrenia within 6 months before screening period. * Assessed by the investigator as having treatment-resistant schizophrenia; past or current diagnosis of neuroleptic malignant syndrome (NMS); anticipated need for antipsychotic regimen modifications during the study period; * History of suicide attempts (including actual attempts, interrupted attempts, or failed attempts) or suicidal ideation within the past 6 months, defined as affirmative responses (yes) to question 4 or 5 on the Columbia-Suicide Severity Rating Scale (C-SSRS) at screening/baseline; * Subjects have used monoamine oxidase inhibitors (MAOI) within 28 days or any dietary supplements/traditional Chinese herbal products within 7 days prior to first dosing. * Glycated hemoglobin (HbA1c) ≥7% at screening/baseline. * Congenital long QT syndrome; uncontrolled or severe cardiovascular disease, including NYHA class II or higher congestive heart failure, unstable angina, myocardial infarction within 6 months prior to screening, or presence of treatment-requiring severe arrhythmias (e.g., sustained ventricular tachycardia, ventricular fibrillation, torsades de pointes) at screening; resting heart rate \<50 beats per minute (bpm) at screening/baseline; or QTc \>450 ms (male) / QTc \>460 ms (female) based on Fridericia's formula-corrected measurements at screening/baseline. * Subjects experienced a history of keratopathy, fundus disease, increased intraocular pressure, or angle-closure glaucoma. Subjects have any abnormal and clinically significant test for ophthalmic examination during screening. * Subjects with a history of orthostatic hypotension or syncope.

| Measure | Time frame |
|---|---|
| Number of participants with adverse events (AEs) and serious adverse events (SAEs). | up to Day 11 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| AUC Accumulation Ratio (Ra(AUC)) of LPM787000048 in plasma | up to Day 11 | — |
| Cmax Accumulation Ratio (Ra(Cmax)) of LPM787000048 in plasma | up to Day 11 | — |
| Number of participants with vital sign abnormalities. | up to Day 11 | — |
| Number of participants with 12-lead electrocardiogram abnormalities (ECGs). | up to Day 11 | — |
| Number of participants with ophthalmic examination abnormalities. | up to Day 11 | — |
| Change from Baseline in Simpson-Angus Scale (SAS) at Day4 and Day 11 of subjects with stable schizophrenia | up to Day 11 | This scale consists of 10 items, and each question is scored from 0 to 4 points. The Total score range is 0 to 40.A higher score is associated with greater illness severity. |
| Maximum observed concentration at steady state (Cmax,ss) of LPM787000048 in plasma | up to Day 11 | — |
| Apparent terminal elimination half-life (t1/2) of LPM787000048 in plasma | up to Day 11 | — |
| Area under the concentration- time curve during the dosing interval at steady state (AUC0-τ,ss) of LPM787000048 in plasma | up to Day 11 | — |
| Area under the concentration-time curve from time zero extrapolated to infinity at steady state (AUC0-∞,ss) of LPM787000048 in plasma | up to Day 11 | — |
| Number of participants with clinical laboratory assessment abnormalities. | up to Day 11 | — |
| Change from Baseline in Positive and Negative Syndrome Scale (PANSS) at Day 11 of subjects with stable schizophrenia | up to Day 11 | The total score range is 30 to 210.A higher score is associated with greater illness severity. |
| Change from Baseline in Columbia - Suicide Severity Rating Scale (C-SSRS) at Day 11 of subjects with stable schizophrenia | up to Day 11 | This scale is divided into three parts, which are evaluated suicidal ideation(5 items \[yes/no\]),intensity of ideation (5 items on 5-point scales; scores range from 0 to 25 with higher scores indicating more intense suicidal ideation),and suicide behavior(actual attempt,interrupted attempt,aborted attempt, preparatory acts or behavior). |
| Change from Baseline in Barnes Akathisia Rating Scale (BARS) at Day4 and Day 11 of subjects with stable schizophrenia | up to Day 11 | The total score range is 0 to 14.A higher score is associated with greater illness severity. |
| Time to maximum observed concentration at steady (Tmax,ss) state of LPM787000048 in plasma | up to Day 11 | — |
| Minimum observed concentration at steady state (Cmin,ss) of LPM787000048 in plasma | up to Day 11 | — |
