Safety and Efficacy Evaluation of LC-K76 in Patients With Metastatic Hormone-Sensitive Prostate Cancer

Inclusion Criteria:

1. Male, aged ≥ 18 years.
2. Histologically or cytologically confirmed newly diagnosed metastatic hormone-sensitive prostate adenocarcinoma, without small cell carcinoma or small cell components.
3. Presence of at least one bone metastasis or visceral metastasis (excluding lymph nodes) detected by systemic imaging (CT/MRI).
4. No prior treatment for prostate cancer before enrollment (including but not limited to radical surgery, radiotherapy, endocrine therapy, or chemotherapy).
5. No history of allergy to dandelion or dandelion products.
6. ECOG performance status ≤ 2.
7. Plan to receive and maintain Androgen Deprivation Therapy (ADT) combined with an androgen receptor antagonist (e.g., enzalutamide, apalutamide, darolutamide), abiraterone acetate, or other drugs inhibiting testosterone synthesis during the study period.
8. Subjects are able to comply with oral LC-K76 capsule administration and adhere to study requirements throughout the study

Exclusion Criteria:

1. Lack of pathological evidence for prostate cancer diagnosis.
2. Prior receipt of any treatment modality for prostate cancer.
3. Patients with other primary malignant tumors that were progressive or required active treatment within the past 3 years.
4. Patients with diabetes requiring continuous insulin therapy or poorly controlled diabetes.
5. Known or suspected central nervous system metastases or active leptomeningeal disease.
6. Significant abnormalities in bone marrow, coagulation, renal, and hepatic function, defined as laboratory values at randomization: Hemoglobin \< 90 g/L, Neutrophils \< 1.5 × 10$\^9$/L, Platelets \< 75 × 10$\^9$/L, ALT \> 2.5 × ULN, AST \> 2.5 × ULN, or Serum Total Bilirubin \> 1.5 × ULN; eGFR \< 60 mL/min/1.73m$\^2$.
7. Any severe disease affecting cardiopulmonary function or high-risk conditions.
8. History of severe drug allergies.
9. Presence of factors interfering with swallowing, chronic diarrhea, intestinal obstruction, or other factors affecting drug intake and absorption.
10. Concurrent psychiatric illness or neurological symptoms judged to make participation difficult.
11. Any condition that, in the judgment of the investigator, poses a severe safety risk to the patient, may confound study results, or may affect the patient's ability to complete the study (e.g., poorly controlled hypertension, severe diabetes, neurological or psychiatric disorders), or any other relevant conditions.
12. Concurrent participation in other clinical trials or use of other investigational drugs.
13. Refusal or inability to sign the informed consent form.
