Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Preoperative SABER
|
Preoperative SABER: Participants will be treated with an assigned dose level of preoperative SABER, delivered in once a day, 5 fractions given on non-consecutive days, over a period of 2 weeks. In this phase I study, starting with dose level II, a dose level of preoperative SABER will be assigned per study dose-escalation design, treating 2 to 6 patients per dose level. The tested doses are the following:

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Recommended Phase 2 Dose (RP2D) of Pre-Operative SABER
Time Frame: Up to 13 Weeks
|
The recommended phase 2 dose (RP2D) of pre-operative SABER therapy will be established as the highest dose level tested for which no more than 1 out of 6 patients experience dose-limiting toxicity (DLT).
Adverse Events (AEs) including DLTs will be evaluated by treating physician using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0
|
Up to 13 Weeks
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants Experiencing Treatment-Related Toxicity
Time Frame: Up to 13 weeks
|
Number of participants experiencing treatment-related toxicity by type and grade including adverse event (AEs), serious adverse events (SAEs) and dose-limiting toxicities (DLTs).
Toxicity will be evaluated using the NCI CTCAE version 5.0.
|
Up to 13 weeks
|
Percentage of participants with Complete Pathological Response (pCR)
Time Frame: Up to 9 weeks
|
pCR will be defined as a negative pathologic specimen for invasive carcinoma.
The specimen used for evaluation will be the tissue samples obtained from standard of care partial mastectomy and axillary surgery as per discretion of treating physician.
|
Up to 9 weeks
|
Cosmesis Evaluation
Time Frame: 1, 6 ,12 and 24 months post-therapy, up to 2.5 years
|
Participant cosmesis will be evaluated-by-physician at 1, 6,12 and 24 months post-SABER therapy and post-surgical follow-up, using the Harvard 4-point ordinal scale (excellent, good, fair, and poor).
|
1, 6 ,12 and 24 months post-therapy, up to 2.5 years
|
Participant-Reported Health-Related Quality of Life (HR-QoL)
Time Frame: 1, 6 ,12 and 24 months post-therapy, up to 2.5 years
|
The Breast Cancer Treatment Outcome Scale (BCTOS) questionnaire will be used to assess participant-reported health-related quality of life (HR-QoL) at 1, 6 12, 24 months post-SABER therapy and post-surgical follow up.
|
1, 6 ,12 and 24 months post-therapy, up to 2.5 years
