Brief Summary:
This phase II trial studies how well T-DMI with or without abemaciclib works for the treatment of HER2-positive breast cancer that has spread to other places in the body (metastatic). T-DM1 is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug called DM1. Trastuzumab attaches to HER2 positive cancer cells in a targeted way and delivers DM1 to kill them. Abemaciclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving T-DM1 and abemaciclib may work better in treating patients with breast cancer compared to T-DM1 alone.

Condition or disease Intervention/treatment Phase
Anatomic Stage IV Breast Cancer AJCC v8 HER2 Positive Breast Carcinoma Metastatic Breast Carcinoma Prognostic Stage IV Breast Cancer AJCC v8 Drug: Abemaciclib Biological: Trastuzumab Emtansine Phase 2

Detailed Description:

PRIMARY OBJECTIVES:

I. To assess whether progression-free survival (PFS) is improved with the addition of abemaciclib to trastuzumab emtansine (T-DM1) for patients with estrogen receptor positive (ER+)HER2-positive advanced or metastatic breast cancer who progressed on treatment with a taxane, trastuzumab and pertuzumab (Cohort 1).

II. To assess whether progression-free survival (PFS) is improved with the addition of abemaciclib to T-DM1 for patients with estrogen receptor negative (ER-) HER2-positive advanced or metastatic breast cancer who progressed on treatment with a taxane, trastuzumab and pertuzumab (Cohort 2).

SECONDARY OBJECTIVES:

I. To assess the safety and tolerability of each treatment regimen. II. To assess overall survival (OS) and objective response rate (ORR) of each treatment regimen.

CORRELATIVE RESEARCH OBJECTIVES:

I. To assess whether the presence of vimentin expression or the level of tumor infiltrating lymphocytes (TILs) in the baseline tumor specimen is associated with an increased likelihood of longer PFS in the abemaciclib arms compared to the non-abemaciclib arms (regardless of ER status).

II. To assess both the baseline prognostic effects of circulating tumor cell (CTC) levels, ER expression in CTCs, HER2 expression in CTCs, serum TK1 levels, circulating tumor-derived deoxyribonucleic acid (ctDNA), ESR1, or PIK3CA mutations and whether a reduction in these levels after 2 cycles of treatment is associated with an increased likelihood of longer PFS overall and separately in the treatment arms.

III. To assess whether polymorphisms in FCgamma receptors (FCGR2A and FCGR3A) are associated with inferior PFS.

IV. To describe alterations seen in the peripheral blood immune system architecture after 2 cycles of treatment.

V. To assess whether peripheral blood immune markers at baseline are prognostic and whether change in peripheral blood immune markers after 2 cycles of treatment are associated with PFS.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM A: Patients receive T-DM1 intravenously (IV) over 90 minutes on day 1. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.

ARM B: Patients receive T-DM1 IV over 90 minutes on day 1 and abemaciclib orally (PO) twice daily (BID) on days 1-21. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed every 6 months for up to 5 years.

Primary Outcome Measures :
  1. Progression-free survival (PFS) [ Time Frame: The time elapsed between treatment initiation and tumor progression or death from any cause, assessed up to 5 years ]
    For each treatment arm, the distribution of PFS times will be estimated using the Kaplan-Meier method. A stratified log rank test) will be used to assess whether the PFS is increased with the addition of abemaciclib to trastuzumab emtansine (T-DM1). Also, a point and interval estimate of the hazard of progression with abemaciclib plus T-DM1 relative to the hazard of progression with abemaciclib alone with be obtained from the results of fitting a stratified Cox model with treatment arm as the covariate.


Secondary Outcome Measures :
  1. Incidence of adverse events [ Time Frame: Up to 5 years ]
    Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 will be used to grade and assign attribution to each adverse event reported. For each treatment arm, the proportion of patients who report developing a grade 2-5 of this adverse event (AE) will be determined.

  2. Overall response rate (ORR) [ Time Frame: Up to 5 years ]
    ORR is defined as the number of patients whose disease meets the Response Evaluation Criteria in Solid Tumors (RECIST) for a partial (PR) or complete (CR) on two consecutive evaluations at least 12 weeks apart divided by the total number of patients in that cohort who started protocol treatment. For each treatment arm, a 90% binomial confidence interval will be constructed for the true overall response rate.

  3. Duration of response [ Time Frame: Up to 5 years ]
    For the patients whose disease responded to treatment by meeting the criteria for CR or PR on two consecutive evaluations at least 12 weeks apart, the duration of response will be tabulated.

  4. Overall survival (OS) [ Time Frame: From randomization to death due to any cause, assessed up to 5 years ]
    Overall survival estimates for each treatment arm will be determined using the Kaplan Meier method. This study was not designed to compare the OS distributions of these 2 treatment regimens. As such, no hypothesis testing will be performed. A point and interval estimate of the hazard of death with abemaciclib plus T-DM1 relative to the hazard of progression with abemaciclib alone with be obtained from the results of fitting a stratified Cox model with treatment arm as the covariate.
