* Those who have a history of psychotropic drug abuse and cannot quit or have mental disorders.
* Decompensated stage of cirrhosis and history of hepatic encephalopathy.
* Subjects with clinically significant cardiovascular disease, including any of the following:

  1. Participants who had acute myocardial infarction and severe/unstable angina pectoris within 6 months before the start of study treatment; Or have heart failure of the New York Heart Association's heart function classification level 2 or higher;
  2. QT interval prolongation at rest as corrected by Fridericia Formula (QTcF), QTc interval ≥450ms(male), QTc interval ≥470 ms(female);
  3. Have a past or ongoing history of severe uncontrolled ventricular arrhythmias requiring medical treatment;
  4. Left ventricular ejection fraction (LVEF) \< 50%;
  5. Congenital long QT syndrome, or any known history of tip torsion ventricular Torsades de Pointes (TdP);
  6. Clinically uncontrolled hypertension (systolic blood pressure ≥150 mmHg and/or diastolic blood pressure ≥90 mmHg after standard antihypertensive therapy) and a history of hypertensive encephalopathy/hypertensive crisis.

Active or uncontrolled severe infection (≥CTC AEv5.0 grade 2 infection).

* Patients with renal failure requiring hemodialysis or peritoneal dialysis.
* Have a history of immunodeficiency, including HIV positivity or other acquired or congenital immunodeficiency diseases.
* Subjects with (non-infectious) pneumonia/interstitial lung disease requiring steroid treatment or who currently have non-infectious pneumonia/interstitial lung disease or have been hospitalized for any active infection or received therapeutic antibiotics in the 4 weeks prior to beginning study treatment, including but not limited to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection.
* People who have epilepsy and need treatment.
* Urine routine indicated urine protein ≥ ++, and confirmed 24-hour urine protein quantity \> 1.0 g.
* Poor diabetes control (fasting blood glucose (FBG) \> 10mmol/L).
* Tumor-related symptoms and treatment:

  1. For subjects who have received chemotherapy, immunotherapy within 4 weeks prior to the first dose, radiation therapy or small molecule targeted drugs within 2 weeks, or who are still within the 5 half-lives of the drug (depending on the shortest time of occurrence), the washout period is calculated from the end time of the last treatment;
  2.

  4. Uncontrolled pleuroceliac or pericardial effusion requiring repeated drainage or obvious symptoms. Subjects who are asymptomatic and have not received drainage or other treatment in the first 2 weeks of enrollment can be enrolled if imaging shows only small amounts of pleural effusion, ascites, or pericardial effusion.
* Known allergy to study drug excipients.
* Previous therapy with targeted ROR1 inhibitors.
* Participants who have participated in a clinical trial of another antitumor drug (calculated as the last use of the investigational drug) within 4 weeks prior to initial administration and have used the investigational drug, or are still within 5 half-lives of the investigational drug (whichever is shorter).
