Brief Summary
The study comprises three parts: single ascending dose (SAD) studies of CX2101A tablets at 40 mg, 100 mg, and 160 mg; a relative bioavailability (BA) study comparing single-dose administration of 100 mg CX2101A tablets and enteric-coated tablets; and a multiple ascending dose (MAD) study of CX2101A tablets. The BA study (100 mg) is integrated into the SAD study(Nested within the SAD protocol to optimize resource utilization).

Eligibility Criteria
You may qualify if:
- Healthy volunteers aged between 18 and 55 years old (including 18 and 55 years old), regardless of gender.
- For male volunteers, the body weight should be ≥ 50.0 kg, and for female volunteers, the body weight should be ≥ 45.0 kg. The body mass index (BMI) = body weight (kg) / height² (m²), and it should be within the range of 19.0 to 28.0 kg/m². Women of childbearing potential (WOCBP) or the female partners of male subjects should be willing to have no plans for childbearing from 2 weeks before the screening until 1 months after the last administration of the investigational medicinal product, and voluntarily adopt effective contraceptive measures (including one or more non-pharmacological contraceptive measures), and have no plans for sperm donation or egg donation.
- No history of major diseases, and the results of physical examination, vital signs, 12-lead electrocardiogram, chest X-ray examination and laboratory tests during the screening period are normal, or although slightly beyond the normal reference value range, they are judged by the investigator to have no clinical significance.
- The subject should be able to maintain good communication with the investigator, comply with various requirements of the clinical trial, and voluntarily sign the informed consent form.
You may not qualify if:
- Diseases with abnormal clinical manifestations that occurred before screening or are currently occurring and need to be excluded, including but not limited to those in the nervous/mental system, respiratory system, cardiovascular and cerebrovascular system, digestive system (any history of gastrointestinal diseases that affect drug absorption), hematological and lymphatic system, urinary system, endocrine system, and immune system.
- Acute diseases that occurred from the screening stage to before the first administration of the investigational medicinal product and are judged by the investigator to possibly affect the research results.
- Subjects who cannot tolerate intravenous puncture or those with a history of syncope judged by the investigator to be of clinical significance.
- Subjects with difficulty in swallowing.
- Subjects who are judged by the investigator to possibly or definitely have an allergic reaction to the investigational drug (including similar drugs), or any of its excipients; or subjects with an allergic constitution judged by the investigator to be of clinical significance (a history of severe allergies to multiple drugs and foods) or a history of allergic diseases.
- Subjects who have undergone surgery before screening and are judged by the investigator to possibly affect the absorption, distribution, metabolism, and excretion of the drug, or subjects with severe surgical sequelae, or subjects who plan to undergo surgery during the study period.
- Subjects who donated blood or had massive blood loss (≥ 400 mL), donated ≥ 2 units of component blood, or received a blood transfusion within 3 months before screening, or those who plan to donate blood during the trial.
- Subjects who received any investigational drug in a clinical study or participated in any interventional clinical study within 3 months before screening.
- Subjects who smoked an average of more than 5 cigarettes per day within 3 months before screening, or those who cannot stop using any tobacco products during the trial.
- Subjects who consumed an average of more than 14 units of alcohol per week within 3 months before screening (1 unit of alcohol ≈ 360 mL of beer or 45 mL of spirits with an alcohol content of 40% or 150 mL of wine), or those who cannot stop using any alcohol-containing products during the trial, or those with a positive alcohol breath test before the administration of the trial.
- Subjects who consumed an excessive amount of tea, coffee, and/or caffeine-containing beverages on average per day (more than 8 cups on average, 1 cup ≈ 250 mL) within 3 months before screening, or those who cannot stop consuming tea, coffee, and/or caffeine-containing beverages during the trial.
- Subjects who used any prescription drugs, over-the-counter drugs, traditional Chinese patent medicines, Chinese herbal medicines, vitamins, or health foods within 28 days before screening or within 5 drug half-lives (whichever is longer).
- Female subjects who are pregnant or breastfeeding, or those with a positive blood/urine pregnancy test (only for WOCBP) at any time during screening.
- Positive results or results exceeding the upper limit of the reference range for the four hemodialysis tests: hepatitis B surface antigen (HBsAg), quantitative hepatitis C (HCV) antibody, quantitative human immunodeficiency virus (HIV) antibody, or treponema pallidum antibody.
- Subjects with a positive urine drug screening (morphine, tetrahydrocannabinolic acid, methamphetamine, methylenedioxymethamphetamine, ketamine) or those with a history of drug abuse or drug use within the past 5 years before the trial.
