Study type | Interventional |
Phase III, prospective, multi-center, randomized, open label, parallel group, study in patients with HER2-negative breast cancer with residual disease after neoadjuvant chemotherapy with 1:1 allocation to: - Arm A: Sacituzumab govitecan (days 1, 8 q3w for eight cycles); - Arm B: treatment of physician´s choice (TPC, defined as capecitabine or platinum-based chemotherapy for eight cycles or observation. Treatment in either arm will be given for eight cycles. In patients with HR-positive breast cancer, endocrine-based therapy, which includes the use of CDK4/6 inhibitors, will be administered according to local guidelines. The start of endocrine therapy will be at the discretion of the investigator; however, it will be encouraged to start after surgery/radiotherapy in patients without additional cytotoxic agents. Adjuvant pembrolizumab can be given until the completion of radiotherapy before randomization. Within the study the use of pembrolizumab in patients with TNBC who received pembrolizumab as neoadjuvant therapy is allowed as monotherapy in the TPC arm, according to the approval of pembrolizumab in this setting.

Age at diagnosis at least 18 years. 3. Willingness and ability to provide archived formalin fixed paraffin embedded tissue (FFPE) block from surgery after neoadjuvant chemotherapy and from core biopsy before start of neoadjuvant chemotherapy, which will be used for centralized prospective confirmation of HR status, HER2 status, Ki-67 and tumor-infiltrating lymphocytes (TILs) and for retrospective exploratory correlation between genes, proteins, and mRNAs relevant to sensitivity/resistance to the investigational agents. For patients with bilateral carcinoma, FFPE blocks from both sides have to be provided for central testing. 4. Histologically confirmed unilateral or bilateral primary invasive carcinoma of the breast, confirmed histologically by core biopsy. The lead tumor has to be defined by the investigator based on the inclusion criteria for the respective subtype and on the risk status. 5. Centrally confirmed HER2-negative (IHC score 0-1 or FISH negative according to ASCO/CAP guideline) and either - HR-positive (=1% positive stained cells) disease or - HR-negative (<1% positive stained cells) assessed preferably on tissue from postneoadjuvant residual invasive disease of the breast, or if not possible, of residual nodal invasion. If not evaluable, core of diagnostic biopsy will be used. In case of bilateral breast cancer, HER2-negative status has to be confirmed for both sides. 6. Patients with residual invasive disease after neoadjuvant chemotherapy at high risk of recurrence defined by either: - For HR-negative: any residual invasive disease > ypT1mi and/or ypN1>1mm - For HR-positive disease: a CPS+EG score = 3 or CPS+EG score 2 and ypN+ using local ER and grade assessed on core biopsies taken before start of neoadjuvant treatment. 7. Adequate surgical treatment including resection of clinically evident disease and ipsilateral axillary lymph node dissection. SNB before NACT is discouraged. Axillary dissection before NACT is not permitted. Axillary dissection, including Targeted Axillary Dissection (TAD) should be performed according to guidelines. Histologic complete resection (R0) of all invasive and in situ tumors is required. 8. Patients must have received neoadjuvant taxane-based chemotherapy for 16 weeks (anthracyclines are permitted). This period must include 6 weeks of a taxane containing neoadjuvant chemotherapy (exception: for patients with progressive disease that occurred after at least 6 weeks of taxane-containing neoadjuvant chemotherapy, a total treatment period of less than 16 weeks is also eligible). 9. No clinical evidence for locoregional or distant relapse during or after preoperative chemotherapy. Local progression during chemotherapy is not an exclusion criterion if adequate local control could be obtained. 10. In case of local progression during neoadjuvant therapy, distant metastases must be excluded by adequate imaging (CT/MRI recommend) prior to entering the trial. 11. Immune checkpoint inhibitor / immunotherapy during (neo)adjuvant therapy is allowed until the completion of radiotherapy. 12. Patients with known gBRCA1/2 mutation without indication to adjuvant olaparib therapy are allowed to participate in the trial. 13. An interval of less than 16 weeks since the date of final surgery or less than 10 weeks from completing radiotherapy (whichever occurs last) and the date of randomization is required. 14. Radiotherapy should be delivered before the start of study treatment. Radiotherapy to the breast is indicated in all patients with breast conserving surgery and to the chest wall and lymph nodes according to local guidelines as well as in all patients with cT3/4 or ypN+ disease treated by mastectomy. 15. Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1. 16. Resolution of all acute toxic effects of prior anti-cancer therapy or surgical procedure or radiotherapy to NCI CTCAE v 5.0 grade = 1 (except alopecia or other toxicities not considered a safety risk for the patients at the investigator´s discretion). 17.

Marmé F, Hanusch C, Furlanetto J, et al. Safety interim analysis (SIA) of the phase III postneoadjuvant SASCIA study evaluating sacituzumab govitecan (SG) in patients with primary HER2-negative breast cancer (BC) at high relapse risk after neoadjuvant tre
Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Invasive disease free survival (iDFS) between patients treated with sacituzumab govitecan vs. treatment of physician's choice. | iDFS is defined as time from randomization until first iDFS event: local invasive recurrence following mastectomy, local invasive recurrence in the ipsilateral breast following lumpectomy, regional recurrence, distant recurrence, contralateral invasive breast cancer, second non-breast primary cancer (excluding squamous or basal cell carcinoma of the skin), or death from any cause. (according to Hudis (J Clin Oncol 2007) )
There will be one interim analysis for efficacy after 2/3 of the events to allow for early stopping of the trial due to overwhelming efficacy. |
Assuming 3.25 years of recruitment with 12 months ramp-up and 42 patients per month at peak and 3 years of follow-up after the last patient in, 396 events will be needed and final analysis is expected 75 months after study start. | |
Secondary | To compare overall survival (OS) between patients treated with sacituzumab govitecan vs. treatment of physician's choice. | OS is defined as the time from randomization until death from any cause.
One interim analysis of the key secondary endpoint OS will be performed at the time of the final analysis of the iDFS. |
Assuming 3.25 years of recruitment 398 events will be needed with a power of 80% and final analysis is expected after 99 months (8.3 years after first patient in, 2 years after final analysis of iDFS). | |
Secondary | Distant disease-free survival (DDFS) between patients treated with sacituzumab govitecan vs. treatment of physician's choice. | DDFS is defined as the time from randomization until distant recurrence of disease, second primary invasive cancer (non-breast, excluding squamous or basal cell carcinoma of the skin), and death due to any cause. | DDFS will be analyzed at the time of the final iDFS analysis (is expected 75 months after study start) | |
Secondary | To compare the invasive breast cancer-free survival (iBCFS) between both groups. | iBCFS is defined as the time from randomization until first iDFS event excluding any second non-breast primary cancer. | iBCFS will be analyzed at the time of the final iDFS analysis (is expected 75 months after study start) | |
Secondary | Locoregional recurrences-free interval between patients treated with sacituzumab govitecan vs. treatment of physician's choice. | LRRFI is defined as the time from randomization until any loco-regional (ipsilateral breast (invasive), chest wall, local/regional lymph nodes) recurrence of disease or any invasive contralateral breast cancer whichever occurs first. Distant recurrence, secondary malignancy and death are considered as competing risks and will be accounted for in the analysis. | Time-to-Event Outcome Measure up to 75 month after study start. | |
Secondary | iDFS in stratified subgroups. | HR-negative vs. HR-positive ypN+ vs. ypN0. | Will be analyzed at the time of the final iDFS analysis (is expected 75 months after study start) | |
Secondary | OS in stratified subgroups. | HR-negative vs. HR-positive ypN+ vs. ypN0. | Will be analyzed after 99 months (8.3 years after first patient in, 2 years after final analysis of iDFS) | |
Secondary | iDFS in exploratory subgroups. | Prior platinum therapy (TNBC)
Prior immune-checkpoint inhibitor therapy (TNBC) Experimental arm vs. active TPC in TNBC, overall and in subgroups of different active TPC low vs. high TROP2-expression |
Will be analyzed at the time of the final iDFS analysis (is expected 75 months after study start) | |
Secondary | OS in exploratory subgroups. | Prior platinum therapy (TNBC)
Prior immune-checkpoint inhibitor therapy (TNBC) Experimental arm vs. active TPC in TNBC, overall and in subgroups of different active TPC low vs. high TROP2-expression |
Will be analyzed after 99 months (8.3 years after first patient in, 2 years after final analysis of iDFS) | |
Secondary | Safety - To compare safety between patients treated with sacituzumab govitecan vs. treatment of physician's choice. | Frequency and severity of adverse events graded according to the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
One interim analysis for safety will be performed after first 50 patients completed 4 cycles of treatment. |
Final safety analysis will take place when interim analysis of the primary endpoint is performed (all patients will have completed treatment, estimated 54 months from study start) | |
Secondary | Compliance - To compare dose-density, dose reductions, dose delays, treatment interruptions and treatment discontinuation rates between patients treated with sacituzumab govitecan vs. treatment of physician's choice. | Safety, tolerability, and treatment compliance: the number and percentage of patients whose treatment had to be reduced, delayed or permanently stopped will be summarized for each treatment arm, reasons for dose modification, delay and premature termination will be categorized according to the main reason and will be presented in frequency tables. Treatment arms will be compared regarding the occurrence of any adverse events (AE) (grade 1-5), low grade AE (grade 1-2), and high grade AE (grade 3-5) using Fisher's exact test. Those tests are descriptive in nature and no adjustments for multiple comparisons will be made. | Analysis with final safety analysis expected 54 months after study start. | |
Secondary | Patient reported outcome: Functional Assessment of Cancer Therapy - Breast Cancer (FACT-B) | For each treatment group and at each time point, the number and percentage of patients who completed the instrument will be summarized, as well as the reasons for non-completion of these questionnaires, if known.
For each of the FACT-B scales (37 items; 5 point Likert-typ scale; scale from 0-148; the higher the score, the better the QOL) the results will be summarized using descriptive statistics for each treatment group at each time point. Results based on the observed values as well as changes from baseline (including both within group and between group differences) will be displayed. |
Through study completion and until 12 months after End of treatment of single patients. | |
Secondary | Patient reported outcome: Functional Assessment of Cancer Therapy - Cognitive function issues (FACT-Cog) | For each treatment group and at each time point, the number and percentage of patients who completed the instrument will be summarized, as well as the reasons for non-completion of these questionnaires, if known.
For each of the FACT-cog scales (37 items; 5 point Likert-type scale; scale from 0-126; the higher the score, the better the QOL) the results will be summarized using descriptive statistics for each treatment group at each time point. Results based on the observed values as well as changes from baseline (including both within group and between group differences) will be displayed. |
Through study completion and until 12 months after End of treatment of single patients. | |
Secondary | Patient reported outcome: Health Questionnaire 5-Level EQ-5D (EQ-5D-5L) | For each treatment group and at each time point, the number and percentage of patients who completed the instrument will be summarized, as well as the reasons for non-completion of the questionnair, if known.
For the EQ-5D-5L instrument (6 items; 5 times 5 point Likert-type scale; 1-digit number that expresses the level selected for the item; 1 visual analogue scale (0-100mm); the higher the score, the better the QOL) the results will be summarized using descriptive statistics for each treatment group at each time point. Results based on the observed values as well as changes from baseline (including both within group and between group differences) will be displayed. |
Through study completion and until 12 months after End of treatment of single patients. |
