简要总结
Protocol Title:
A single-arm, open-label Phase 4 study of darolutamide in addition to standard androgen
deprivation therapy for participants in India with high-risk non-metastatic castration-resistant
prostate cancer (nmCRPC)
Short Title: Darolutamide for nmCRPC India PAC study
Rationale: This study aims to demonstrate the safety of darolutamide when administered with
androgen deprivation therapy (ADT) in participants Indian with high-risk non-metastatic
castration-resistant prostate cancer (nmCRPC).
Primary Objectives in this study is :
To characterize the safety profile of
darolutamide in Indian participants with high-risk
nmCRPC.
Secondary Objective in this study is :
To determine the effect of darolutamide on
indicators of efficacy in Indian participants with
high-risk nmCRPC

- •Capable of giving signed IC which includes compliance with the requirements, restrictions listed in the informed consent form (ICF), and in this protocol; and providing signed IC.
- •Participant must be male aged ≥ 18 years.
- •Histologically or cytologically confirmed adenocarcinoma of prostate without neuroendocrine differentiation or small cell features.
- •CRPC defined as 3 rising PSA levels after the nadir taken at least 1 week apart during ADT.
- •If the participant has a history of antiandrogen use, the most recent PSA value must be obtained at least 4 weeks after antiandrogen withdrawal.
- •Castrate level of serum testosterone (< 1.7 nmol/L [50 ng/dL]) on gonadotropin releasing hormone (GnRH) agonist or antagonist therapy or after bilateral orchiectomy.
- •Participants who have not undergone bilateral orchiectomy must continue GnRH therapy during the study.
- •PSADT of ≤ 10 months and PSA ≥ 2 ng/mL at screening.
- •Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or
- •Estimated glomerular filtration rate (eGFR) > 15 mL/min/1.73 m2
- •Blood counts at screening: hemoglobin ≥ 9.0 g/dL, absolute neutrophil count ≥ 1500/μL (1.5 × 109/L), platelet count ≥ 100,000/μL (100 ×109/L) (participant must not have received any growth factor or blood transfusion within 7 days of the hematology laboratory obtained at screening).
- •Screening values of serum alanine aminotransferase (ALT) and aspartate transaminase (AST) ≤ 2.5 × upper limit of normal (ULN), total bilirubin ≤ 1.5 × ULN (except participants with a diagnosis of Gilbert’s disease), creatinine ≤ 2.0 × ULN.
- •Sexually active participants, unless surgically sterile, must agree to use a male condom plus partner use of a contraceptive method with a failure rate of <1% per year, and refrain from sperm donation during the study treatment and for 1 week after the last dose of study treatment.
- •Contraceptive use by men should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.
排除标准
- •History of metastatic disease at any time or presence of detectable metastases by investigator assessment within 42 days prior to start of study treatment.
- •Presence of pelvic lymph nodes < 1.5 cm in short axis below the aortic bifurcation is allowed.
- •Acute toxicities of prior treatments and procedures not resolved to Common Terminology Criteria for Adverse Events (CTCAE) v.4.03 grade ≤ 1 or baseline before first dose of study treatment.
- •Severe or uncontrolled concurrent disease, infection, or co-morbidity that, in the opinion of the investigator, would make the participant inappropriate for enrollment.

- •Unwilling or unable to comply with all protocol-required visits and assessments or comply with study requirements.
