简要总结
This phase II trial tests whether niraparib works to shrink tumor in patients with leiomyosarcoma. Niraparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy.
详细描述
PRIMARY OBJECTIVES:
I. To evaluate whether niraparib tosylate monohydrate (niraparib) shows preliminary evidence of clinical activity among subjects with leiomyosarcoma (LMS) with genomic alterations in the homologous recombination (HR) pathway as measured by the confirmed objective response rate (ORR).
SECONDARY OBJECTIVES:
I. To evaluate the clinical benefit rate (CBR) associated with niraparib treatment in the study population.
II. To evaluate the progression free survival (PFS) associated with niraparib treatment in the study population.

入选标准
- •Participant must have histologically documented LMS. Pathology review and confirmation of diagnosis will occur at the site enrolling the patient on this study.
- •Patients must have had a recent, within six months of screening, tumor biopsy testing positive for pathogenic mutation or homozygous loss of either BARD1, BRCA1, BRCA2, BRIP1, PALB2, RAD51, RAD51B, RAD51C, or RAD51D using a clinically validated next-generation (NGS) sequencing panel.
- •Variant pathogenicity will be arbitrated by the primary investigative team
- •Patients must have locally advanced and unresectable or metastatic disease
- •Patients must have disease which is measurable at study entry according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.
- •Additionally, patients must have a site of disease deemed accessible for biopsy at no or minimal risk to the patient (including through the use of image-guidance). If there are questions regarding the feasibility of biopsy, the case should be reviewed with interventional radiology or the appropriate department at the study site
- •Patients must have had prior progression on, or intolerance to, at least one line of systemic therapy for advanced LMS. Adjuvant therapy administered after curative resection will not qualify as prior treatment. There is no upper limit on the number of prior therapies received
- •Participant must have an Eastern Cooperative Oncology Group (ECOG) performance status of =< 2
- •Participant must be >= 18 years of age
- •Absolute neutrophil count >= 1,500/uL
- •Platelets >= 100,000/uL
- •Hemoglobin >= 9 g/dL
- •Serum creatinine =< 1.5 x upper limit of normal (ULN) or calculated creatinine clearance >= 30 mL/min using the Cockcroft-Gault equation
- •Total bilirubin =< 1.5 x ULN (=< 2.0 in patients with known Gilbert's syndrome) OR direct bilirubin =< 1 x ULN
- •Aspartate aminotransferase and alanine aminotransferase =< 2.5 x ULN unless liver metastases are present, in which case they must be =< 5 x ULN
- •Participant receiving corticosteroids may continue as long as their dose is stable for least 4 weeks prior to initiating protocol therapy
- •Female participant has either a negative highly sensitive urine or a serum pregnancy test within 72 hours prior to taking study treatment if of childbearing potential and agrees to abstain from activities that could result in pregnancy from screening through 180 days after the last dose of study treatment, or is of nonchildbearing potential. Nonchildbearing potential is defined as follows (by other than medical reasons):
- •>= 45 years of age and has not had menses for > 1 year
- •Patients who have been amenorrhoeic for < 2 years without history of a hysterectomy and oophorectomy must have a follicle stimulating hormone value in the postmenopausal range upon screening evaluation
- •Post-hysterectomy, post-bilateral oophorectomy, or post-tubal ligation. Documented hysterectomy or oophorectomy must be confirmed with medical records of the actual procedure or confirmed by an ultrasound. Tubal ligation must be confirmed with medical records of the actual procedure, otherwise the patient must be willing to use 2 adequate barrier methods throughout the study, starting with the screening visit through 180 days after the last dose of study treatment. Information must be captured appropriately within the site's source documents. Note: Abstinence is acceptable if this is the established and preferred contraception for the patient.
- •Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the non-estrogen hormonal highly effective contraception methods if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of postmenopausal status before study enrollment
- •Male participant agrees to use an adequate method of contraception starting with the first dose of study treatment through 90 days after the last dose of study treatment. Note: Abstinence is acceptable if this is the established and preferred contraception for the patient
- •Participant must be able to understand the study procedures and agree to participate in the study by providing written informed consent
- •Participant must have normal blood pressure or adequately treated and controlled hypertension (i.e. systolic blood pressure =< 140 mmHg and diastolic blood pressure =< 90 mmHg).
排除标准
- •Patients must not have had any previous treatment with any poly(adenosine diphosphate[ADP]-ribose) polymerase (PARP) inhibitors
- •Participant must not be simultaneously enrolled in any interventional clinical trial
- •Participant must not have had major surgery =< 4 weeks prior to initiating protocol therapy and participant must have recovered from any surgical effects
- •Participant must not have received investigational therapy =< 4 weeks, or within a time interval less than at least 5 half-lives of the investigational agent, whichever is shorter, prior initiating protocol therapy
- •Participant receiving non-steroidal anti-estrogen agents must discontinue their use at least two weeks prior to study entry
- •Participant has had radiation therapy encompassing > 20% of the bone marrow within 2 weeks; or any radiation therapy within 1 week prior to Day 1 of protocol therapy
- •Participant must not have a known hypersensitivity to niraparib components or excipients.
- •Participant must not have received a transfusion (platelets or red blood cells) =<4 weeks prior to initiating protocol therapy

- •Participant has had any known Grade 3 or 4 anemia, neutropenia or thrombocytopenia due to prior chemotherapy that persisted > 4 weeks and was related to the most recent treatment
- •Participant must not have any known history or current diagnosis of myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML)

研究组 & 干预措施
Treatment (Niraparib)
Experimental
Patients receive niraparib PO QD. Cycles repeat every 28 days for 15 months in the absence of disease progression or unacceptable toxicity.
干预措施: Niraparib Tosylate Monohydrate (Drug)
结局指标
主要结局
Confirmed objective response rate (ORR)
时间窗: Within first 6 months of study treatment
Defined as complete response + partial response measured by Response Evaluation Criteria in Solid Tumors version 1.1 (RECISTv1.1). Will be calculated as the proportion of patients who achieve a response (complete response + partial response) within the first 6 months of treatment divided by the total number of evaluable patients. An evaluable patient is defined as an eligible patient who has received at least one dose of therapy. All evaluable patients will be included in calculating the ORR for the study along with corresponding 95% binomial confidence intervals (CIs) (assuming that the number of patients who respond is binomially distributed).
次要结局
- Incidence of adverse events (AEs)(Up to 2 years after study treatment)
- Confirmed clinical benefit rate (CBR)(Within first 6 months of study treatment)
- Progression-free survival (PFS)(From first treatment with the study drug to the earliest of either disease progression or death from any cause, assessed up to 2 years)
- Overall survival (OS)(From first treatment with the study drug to the death from any cause, assessed up to 2 years)
