简要总结
This was a single center, proof-of-concept (PoC), Phase II study. Patients with histologically confirmed early stage (Stage I, II or III) HER-2 negative breast cancer and scheduled to receive doxorubicin-based (neo)adjuvant therapy to be followed by paclitaxel or docetaxel as per clinical practice. The planned doxorubicin-based chemotherapy treatment consisted of doxorubicin 60 mg/m2 in combination with cyclophosphamide 600 mg/m2 (AC) intravenous (IV) every 2 or 3 weeks for 4 cycles. Patients were scheduled for CMRI and 99mTc-rhAnnexin V-128 imaging (planar and SPECT / CT) at the following visits:
- Screening/baseline, i.e. 2 weeks prior to initiating AC treatment (Visit 1)
- After the 2nd and before the 3rd cycle of AC treatment (Visit 2)
- After the 4th cycle of AC treatment and within 2 weeks (Visit 3)
- At 12 weeks after the 4th cycle of AC treatment (Visit 4). The imaging procedures were conducted and analyzed. Bloodwork for cardiotoxicity biomarkers (troponin, N terminal pro B-type natriuretic peptide [NT-proBNP]) was performed at each visit.
详细描述
Overall, it was planned to recruit 30 adults with early stage breast cancer. The first 10 patients were to be enrolled in the PoC phase of the study to assess the potential of 99mTc-rhAnnexin V-128 in terms of imaging quality, uptake and medical relevance. Based on the results of the first 10 patients, the DMC was to decide whether to terminate the study or continue to the Phase II and enroll the next 20 planned patients. The maximum study duration was 26 (±4) weeks per patient (including the screening and follow-up periods).
The sponsor decided to terminate the study earlier than planned due to strategic decisions to focus the AAA development portfolio on oncology theragnostics and not based on safety concerns.

主要结局
Part I / Proof of Concept (PoC): Number of Participants Evaluated for Imaging Feasibility
时间窗: Day 0 (Baseline)
The feasibility of imaging apoptotic activity using 99mTc-rhAnnexin V-128 was assessed in the first 10 patients who enrolled and completed the PoC phase of the study by the data monitoring committee (visual image review and consensus). The three reviewers of the DMC did an independent visual assessment of the images using a 1 to 4 point grading system: each observer reviewed the images of each patient and scored either 1 or 2 (uptake was less than or equal to blood pool), these images were considered normal; 3 was equivocal and four equalled abnormal. Only descriptive analysis performed.
次要结局
- 99mTc-rhAnnexin V-128 Myocardial Uptake(60 and 120 minutes post injection at: Day 0 (Baseline), Visit 2 (After the 2nd and before the 3rd cycle of doxorubicin), Visit 3 (After the 4th cycle of doxorubicin and within 2 weeks), Visit 4 (12 weeks after the 4th cycle of doxorubicin))
- Changes in Left Ventricular (LV) Function(Day 0 (Baseline), Visit 2 (After the 2nd and before the 3rd cycle of doxorubicin), Visit 3 (After the 4th cycle of doxorubicin and within 2 weeks), Visit 4 (12 weeks after the 4th cycle of doxorubicin))
- Changes in the Cardiotoxicity Biomarkers (Troponin and NT-proBNP)(Day 0 (Baseline), Visit 2 (After the 2nd and before the 3rd cycle of doxorubicin), Visit 3 (After the 4th cycle of doxorubicin and within 2 weeks), Visit 4 (12 weeks after the 4th cycle of doxorubicin))
