Brief Summary:
Women with Hormone Receptor (HR)+ Human Epidermal growth factor Receptor (HER)2- metastatic breast cancer are eligible to a randomized trial. Patients receiving standard first line therapy for metastatic HR+ Breast cancer(BC) (letrozole+palbociclib) are randomly assigned to also receive Stereotactic Body Radiation Therapy(SBRT) to each metastatic lesion.

Condition or disease Intervention/treatment Phase
Breast Cancer Radiation: Stereotactic Body Radiation Therapy (SBRT) (50GY in 5 fractions) Drug: Letrozole 2.5Mg Tab Drug: Palbociclib 125mg Phase 2

Arm Intervention/treatment
Active Comparator: ARM 1 - Letrozole and Palbociclib
Patients randomized to arm 1 will start standard Letrozole followed by Palbociclib at day 21.
Drug: Letrozole 2.5Mg Tab
All patients start standard therapy with oral letrozole (Femara), day 1 of the study.

Drug: Palbociclib 125mg
Patients randomized to arm 2 will start letrozole alone, and add palbociclib on day 21, after completion of I-SBRT.

Active Comparator: ARM 2 - Letrozole and Palbociclib + I-SBRT
Patients randomized to arm 2 will start letrozole alone, and add palbociclib on day 21, after completion of I-SBRT. Treatment may be given daily (to keep the total I-SBRT treatment time to ≤ 12 days) and lesions targeted with I-SBRT will thus be alternated each day to accommodate for the 48 hour interval between fractions.
Radiation: Stereotactic Body Radiation Therapy (SBRT) (50GY in 5 fractions)
Patients randomized to arm 2 will start letrozole alone, and add palbociclib on day 21, after completion of I-SBRT. They will undergo tumor Immunogenic-SBRT(I-SBRT) days 1-12 (+/-2 days, to enable inclusion of holidays). During the week preceding day 1, they will undergo simulation and planning for radiotherapy. Each oligometastatic lesion will be treated with I-SBRT every 48 hours. Treatment may be given daily (to keep the total I-SBRT treatment time to ≤ 12 days) and lesions targeted with I-SBRT will thus be alternated each day to accommodate for the 48 hour interval between fractions

Drug: Letrozole 2.5Mg Tab
All patients start standard therapy with oral letrozole (Femara), day 1 of the study.

Drug: Palbociclib 125mg
Patients randomized to arm 2 will start letrozole alone, and add palbociclib on day 21, after completion of I-SBRT.




Primary Outcome Measures :
  1. Progression free survival (PFS) will be measured [ Time Frame: End of study, up to 36 months. ]
    Progression free survival (PFS) is defined as the time from the start of study treatment until the disease progression or death.


Secondary Outcome Measures :
  1. Serial levels of Circulating tumor DNA (ctDNA) [ Time Frame: End of study, up to 36 months. ]
    Serial levels ctDNA can be an early indication of progression

  2. Circulating tumor DNA (ctDNA) levels [ Time Frame: End of study, up to 36 months. ]
    Circulating tumor DNA (ctDNA) levels will be measured to determine baseline cancer heterogeneity and its response to treatment

  3. Objective response rate (ORR) will be assessed. [ Time Frame: End of study, up to 36 months. ]
    ORR is defined as the percentage of subjects with either a confirmed complete response (CR) or partial response (PR).

  4. Overall survival(OS) will be assessed. [ Time Frame: End of study, up to 36 months. ]
    OS is defined as the time from the start of treatment until death.

  5. Change in Number of Subjects with Adverse events [ Time Frame: End of study, up to 36 months. ]
    Adverse events will be collected from patients based on CTCAE version 5.0.
