入选标准
- •2. >18 years of age (or the legal age of consent in the jurisdiction in
- •which the study is taking place).
- •3. Signed main study ICF indicating that the subject understands the purpose of, and procedures required for, the study and is willing to participate in the study.
- •4. Histologically confirmed prostate cancer (mixed histology is
- •acceptable, with the exception of the small cell pure phenotype, which is be excluded).
- •5. Documented evidence of disease progression while on treatment with at least 1 taxane-based chemotherapy for prostate cancer
- •6. Documented evidence of disease progression while on treatment with at least 1 AR-targeted therapy (eg, abiraterone acetate, enzalutamide, apalutamide) for prostate cancer.
- •7. Tumor that is biomarker- positive for DNA-repair anomalies.
- •8. Progression of metastatic prostate cancer in the setting of castrate levels of testosterone =50 ng/dL on a gonadotropin releasing hormone analog (GnRHa), or history of bilateral orchiectomy at study entry defined as having one or more of the following:
- •a. PSA progression defined by a minimum of 2 rising PSA levels with an interval of =1 week between each determination (per Prostate Cancer Working Group 3 [PCWG3] criteria). The PSA level at the screening visit should be =2 µg/L (2 ng/mL).
- •b. Radiographic progression of soft tissue by RECIST 1.1 or bone disease by PCWG3 criteria as defined below:
- •I. Soft tissue disease (measurable) by RECIST 1.1 defined as having one or more of the following:
- •i. Nodal disease (pelvic or extrapelvic [retroperitoneal, mediastinal,
- •thoracic, other]) with lesions =1.5 cm in the short axis.
- •ii. Visceral disease (lung, liver, adrenal) with lesions =1 cm in the long axis.
- •II. Bone disease (non-measurable) defined as having bone lesions in the absence of measurable soft tissue disease.
- •9. Must be able to continue GnRHa during the course of the study if not surgically castrate.
- •10. Eastern Cooperative Oncology Group Performance Status (ECOG PS) of =2.
- •11. Must be able to swallow whole capsules.
- •12. Subject must agree to use medically accepted and highly effective methods of contraception during the course of the study and for 3 months after the last dose of study drug.
- •13. To avoid risk of drug exposure through the ejaculate (even men with vasectomies), subjects must agree while on study drug and for 3 months following the last dose of study drug to:
- •a. Use a condom during sexual activity.
- •b. Not donate sperm.
- •14. At screening, the following laboratory parameters must be met:
- •a. Absolute neutrophil count (ANC) =1.5 x 10^9/L
- •b. Hemoglobin =9.0 g/dL
- •c. Platelet count =100 x 10^9/L
- •d. Serum albumin =3 g/dL
- •e. Serum creatinine =1.5 × upper limit of normal (ULN), or a calculated creatinine clearance =60 mL/min using the Cockcroft-Gault equation
- •f. Serum potassium =3.5 mmol/L
- •g. Serum total bilirubin =1.5 × ULN or direct bilirubin =1 x ULN (Note: in subjects with Gilbert's syndrome, if total bilirubin is >1.5 × ULN, measure direct and indirect bilirubin, and if direct bilirubin is =1.5 × ULN, subject may be eligible)
- •h. Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) =3.0 × ULN or =5 x ULN in the presence of liver metastases i. i CTC count of =1 cells/7.5 mL blood
- •Are the trial subjects under 18? no
- •Number of subjects for this age range:
- •F.1.2 Adults (18-64 years) yes
- •F.1.2.1 Number of subjects for this age range 64
- •F.1.3 Elderly (>=65 years) yes
- •F.1.3.1 Number of subjects for this age range 96
排除标准
- •1. Prior treatment with a PARP inhibitor.
- •2. Prior platinum-based chemotherapy for the treatment of prostate cancer.
- •3. Known history or current diagnosis of myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML).
- •4. Known symptomatic or impending cord compression, except if subject has received definitive treatment for this and demonstrates evidence of clinically stable disease.
- •5. Known symptomatic uncontrolled brain or leptomeningeal metastases (controlled is defined as CNS disease which has undergone treatment
- •[eg, radiation or surgery] at least 15 days prior to Cycle 1 Day 1).
- •6. Known allergies, hypersensitivity, or intolerance to niraparib or its excipients (refer to Investigator's Brochure).
- •7. Any condition for which, in the opinion of the investigator, participation would not be in the best interest of the subject (eg, compromise the well-being) or that could prevent, limit, or confound the
- •protocol-specified assessments.
- •8. Known disorder affecting gastrointestinal absorption.
- •9. Active cancer (other than prostate cancer; or basal cell or squamous cell skin cancer, non-muscle invasive bladder cancer [stages pTaG1 and
- •pTaG2], or any other cancer in situ currently in complete remission) within 2 years prior to Cycle 1 Day 1.
- •10. Prior radiotherapy =15 days prior to Cycle 1 Day 1, with the exception of a single fraction of radiotherapy for the purposes of palliation, which is permitted.
- •11. Corrected QT interval by the Fridericia correction formula (QTcF) on the screening ECG >450 msec.
- •12. Receiving concomitant medications that prolong QTc and are unable to discontinue use while receiving study drug.
- •13. History of clinically significant ventricular arrhythmias (eg, ventricular tachycardia, ventricular fibrillation, torsades de pointes).
- •14. HIV positive subjects with 1 or more of the following:
- •a. Not receiving highly active antiretroviral therapy
- •b. A change in antiretroviral therapy within 6 months of the start of screening(except if, after consultation with the sponsor on exclusion criterion 14.c, a change is made to avoid a potential drug-drug
- •interaction with the study drug)
- •c. Receiving antiretroviral therapy that may interfere with the study drug consult the sponsor for review of medication prior to enrollment)
- •d. CD4 count <350 at screening
- •e. An acquired immunodeficiency syndrome-defining opportunistic infection within 6 months of the start of screening
