Brief Summary:
This is a 3-arm study stratified by plasma ctDNA. Patients with residual TNBC disease after pre-operative therapy will be assigned to 1 of 3 Arms based on plasma ctDNA positivity and genomic marker(s).

Condition or disease Intervention/treatment Phase
Breast Cancer Triple Negative Breast Cancer Drug: Capecitabine Drug: Talazoparib Drug: Atezolizumab Drug: Inavolisib Other: Treatment of Choice Phase 2

Detailed Description:

Participants that are plasma ctDNA positive with a genomic target will be assigned to one of the three groups in Arm 1 and receive genomically directed therapy.

  • Arm 1a: DNA Repair pathway = talazoparib + capecitabine (CLOSED)
  • Arm 1b: Immunotherapy pathway = atezolizumab + capecitabine
  • Arm 1c: PI3K Pathway = inavolisib + capecitabine ---> atezolizumab
  • Arm 1d: DNA Repair + Immunotherapy = talazoparib + atezolizumab + capecitabine

Participants that are plasma ctDNA positive without a genomic target will be assigned to Arm 2 and receive capecitabine or treatment of physician's choice.

Participants that are plasma ctDNA negative will be assigned to Arm 3 and receive any of the following based on patient and physician decision: no therapy/observation, capecitabine or treatment of physician's choice.

NOTE: ER and PR will be considered negative if ≤ 10% of cells stain weakly positive. HER2 will be considered negative if scored 0 or 1+ by immunohistochemistry (IHC) or 2+ by IHC associated with a fluorescence in situ hybridization (FISH) ratio of < 2.0 or < 6 copies per cell.
  • Must have clinical stage I-III at diagnosis (AJCC 8th edition) based on initial evaluation by physical examination and/or breast imaging prior to neoadjuvant chemotherapy.

Participants who received preoperative therapy as part of a clinical trial may enroll. Participants may not have received adjuvant chemotherapy after surgery prior to registration. Bisphosphonate use is allowed.
  • Subjects receiving pembrolizumab are eligible and may continue treatment during the screening process. Subjects assigned to Arm 1 will require a 3 week wash out period prior to initiation of study treatment. Subjects assigned to Arm 2 and Arm 3 may continue pembrolizumab treatment during the study based on investigator discretion.
  • Must have significant residual invasive disease at the time of definitive surgery following preoperative chemotherapy. Significant residual disease is defined as at least one of the following:

    • Residual invasive disease in the breast measuring at least 1 cm. The presence of DCIS without invasion does not qualify as residual disease in the breast.
    • Any macroscopic, ≥ 2mm, lymph node involvement regardless of primary tumor site involvement (includes no residual disease in the breast).
    • Residual cancer burden (RCB) score 2 or 3.
  • Must have completed definitive resection of primary tumor. Participants must begin assigned arm therapy no later than 84 days from the last local therapy. NOTE: Negative margins for both invasive and ductal carcinoma in situ (DCIS) are desirable, however participants with positive margins may enroll if the study site treatment team believes no further surgery is possible and participant has received radiotherapy. Participants with margins positive for lobular carcinoma in situ (LCIS) are eligible. Either mastectomy or breast conserving surgery (including lumpectomy or partial mastectomy) is acceptable.

    • In all cases participants must begin arm assigned therapy no later than 84 days from the last local therapy
    • Any acute toxicity must have resolved to grade < 2 prior to starting arm specific therapy.
  • Must consent to allow submission of blood and archived tumor tissue sample from definitive surgery for next generation sequencing of the tumor. Tumor block is preferred however 14 slides + 1H&E can be submitted if necessary. NOTE: Due to possible false positives, ctDNA should not be drawn before completing radiation or less than 14 days from surgery if radiation is not required.

  • Women of childbearing potential must have a negative pregnancy test at screening and within 7 days prior to study registration. Women should be counseled regarding acceptable birth control methods to utilize. If prior to treatment after discussion with the subject it is felt by the treating physician there is a possibility the subject is pregnant a pregnancy test should be repeated. NOTE: Women are considered not of childbearing potential if they are surgically sterile (they have undergone a hysterectomy, bilateral tubal ligation, or bilateral oophorectomy), or they are postmenopausal for at least 12 consecutive months.
  • Women must not be breastfeeding from the time of treatment initiation until the number of days after protocol therapy discontinuation based on package insert or investigator brochure guidelines (See protocol for timeframes).
