NCT ID: NCT05174455

Basic Information

• Recruitment Status: WITHDRAWN
• Clinical Phase: PHASE2
• Study Classification: INTERVENTIONAL
• Study Start Date: 2023-12-01
• Study Completion Date: 2025-12-31

Brief Summary

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.

Detailed Description

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.

III. To evaluate the overall survival (OS) associated with niraparib treatment in the study population.

IV. To evaluate the overall safety and tolerability of niraparib treatment in the study population.

EXPLORATORY OBJECTIVES:

I. To evaluate predictive biomarkers of response to niraparib. II. To evaluate genomic mechanisms of resistance following treatment benefit with niraparib.

III. To evaluate previous treatment response as a marker of response to niraparib.

OUTLINE:

Patients receive niraparib orally (PO) once daily (QD). Cycles repeat every 28 days for 15 months in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 5 years or until death.

Eligibility Criteria

Inclusion Criteria

• 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 1.1. 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).
