Niraparib + Dostarlimab In BRCA Mutated Breast Cancer
|
A Phase II Study of Niraparib With Dostarlimab Therapy as Neoadjuvant Treatment for Patients With BRCA-mutated Breast Cancer
|
This research study involves pre-operative therapy that is specifically targeted for breast cancer in individuals with BRCA and PALB2 mutations.
The names of the study drugs involved in this study are:
- Niraparib (Zejula)
- Dostarlimab
|
The research study procedures include screening for eligibility and study treatment including laboratory evaluations, two mandatory research biopsies, imaging assessments, and follow up visits.
Participants will receive treatment for 18 weeks. After 18 weeks, participants will be evaluated to determine if a candidate for surgery or if additional treatment outside of the study.
Participants with triple negative breast cancer will be randomized to one of two treatment arms.
- Arm A: Niraparib with Dostarlimab for 18 weeks
- Arm B: Niraparib alone for 3 weeks, followed by Niraparib with Dostarlimab for 15 weeks
Participants with estrogen receptor positive breast cancer will be placed directly into Arm C. There is no randomization for these participants.
- Arm C: Niraparib with dostarlimab for 18 weeks
It is expected that about 62 people will take part in this research study.
This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational drug or drug combination to learn whether the drug combination works in treating a specific disease. "Investigational" means that the study drugs, Niraparib and Dostarlimab, are being studied for use in this setting and the research doctors are trying to learn more about the drug combination-the side effects the combination may cause and if it is effective in treating this type of cancer.
The U.S. Food and Drug Administration (FDA) has not yet approved either of the drugs in this study for your type of cancer. Niraparib has been approved by the FDA for treatment of advanced ovarian cancer in BRCA mutation carriers.
The use of Dostarlimab in this research study is experimental, which means that it is not approved by any regulatory auit is not approved by any regulatory authority, including the FDA, for treatment of breast cancer, or any other disease.

Inclusion Criteria:
- Participants must meet the following criteria on screening examination to be eligible to participate in the study. Laboratory assessments for eligibility must be completed within 14 days prior to the date of registration. Diagnostic imaging, such as MRIs and CT scans, must be performed within 28 days of the planned treatment start.
- Participants must have histologically or cytologically confirmed invasive breast cancer Stage I to III with primary tumor size at least 1.5 cm defined by physical exam or imaging (whichever is larger). In the case of a multifocal, multicentric, or bilateral disease, the largest lesion must be ≥ 1.5 cm and designated as the "index" lesion for tumor evaluations. Patients with inflammatory breast carcinoma are not eligible.
-
Participants must have documentation of estrogen receptor (ER) and progesterone receptor (PR) testing by IHC according to local institutional guidelines in a CLIA-approved setting. Central confirmation of ER/PR status is not required. All tumors must be HER2 negative.
- Arms A and B: Target lesion must be ER and PR negative (<10% staining) by local review.
- Arm C: Target lesion must be ER and/or PR positive (>10% staining) by local review.
-
Participants must have documented HER2-negative invasive tumor according to local institutional guidelines in a CLIA-approved setting. Central confirmation of HER2 status is not required. HER2 negative is defined as:
- 0 or 1+ by IHC, OR
- Lack of gene amplification with HER2/CEP17 ratio < 2 by ISH, OR
- Copy number < 6 by ISH
- Participants must have documented germline mutation in BRCA1, BRCA2 or PALB2 that is deleterious or suspected to be deleterious (known or predicted to be detrimental/lead to loss of function). Mutation must be identified through a CLIA-approved laboratory. Final determination of eligibility for any discordant results in pathogenicity will be made by the sponsor-investigator. A formal eligibility exception will not be required in these cases as long as approval by overall study PI is granted and documented.
- Participants with multifocal, multicentric or bilateral disease are eligible if at least one lesion meets criteria for the study. In this circumstance, the investigator must determine which will represent the target lesion to be assessed for response. This should remain consistent throughout the study. The target lesion should be selected on the basis of its size (lesion with the longest diameter) and suitability for accurate repetitive measurements.
- Participants with an eligible target lesion, and another small HER2+ tumor (for example, < 6 mm), may be eligible for enrollment following discussion and agreement with the overall principal investigator. A formal eligibility exception will not be required in these cases as long as approval by the sponsor-investigator is granted and documented.
- Female or male ≥ 18 years of age
- Breast imaging should include imaging of the ipsilateral axilla. For subjects with a clinically positive axilla by physical examination or imaging, axillary tissue acquisition is not required. For patients with a clinically negative axilla by examination and imaging, tissue acquisition is not required. For equivocal imaging findings, tissue acquisition (a needle aspiration, core biopsy) is required. Sentinel Lymph Node (SLN) biopsy before neoadjuvant therapy is not allowed.
- ECOG performance status of 0 or 1
-

Participants who are receiving anticoagulant therapy are eligible as long as PT or partial thromboplastin (PTT) is within therapeutic range of intended use of anticoagulants. Activated partial thromboplastin time (aPTT) must be ≤1.5× ULN unless patient is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants
-
Premenopausal women must have a negative urine or serum pregnancy test within 7 days of treatment start. Women are considered non-childbearing (by other than medical reasons) if they:
- are ≥45 years of age and without menses for >1 year
- have been amenorrhoeic for <2 years without history of a hysterectomy and oophorectomy with a follicle stimulating hormone value in the postmenopausal range upon screening evaluation
- are 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 an adequate barrier method throughout the study, starting with the screening visit through 180 days after the last dose of study treatment. See list of acceptable birth control methods. 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.

- Ability to swallow and retain oral medication.
- Patients undergoing breast conserving therapy (ie lumpectomy) should not have any contraindications to radiation therapy.
- Participants must be willing to undergo the mandatory research biopsy at baseline and after 3 weeks on study treatment. Participants who undergo an attempted research biopsy procedure for the purpose of this protocol and in whom inadequate tissue is obtained are not required to undergo a repeat biopsy in order to continue on the protocol.
Exclusion Criteria:
CT scan pre-medication) are allowed.
- Patients with autoimmune disease that has required systemic treatment within the past 2 years (i.e. with use of disease-modifying agents, corticosteroids, or immunosuppressive drugs). Replacement therapy (e.g. thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
- Patients with a history of interstitial lung disease or pneumonitis.
- Patients who have received a live vaccine within 2 weeks prior to the start of study treatment.
- Patients who have undergone any major surgery within 3 weeks prior to study entry:
patients must have recovered to baseline from any effects of any major surgery.
