Apatinib in Neoadjuvant Therapy for Patients With Breast Cancer

Phase 2

• Conditions: Breast Cancer
• Interventions: Drug: Apatinib; Drug: paclitaxel; Drug: cisplatin

• Registration Number: NCT03580395
• Lead Sponsor: Hebei Medical University Fourth Hospital

Brief Summary

To verify the role of apatinib in neoadjuvant therapy for breast cancer, the investigators designed a prospective, randomized, parallel-controlled phase II/III trial, to investigate the efficacy and safety of apatinib combined with TP (paclitaxel + cisplatin) or TP regimen alone as neoadjuvant therapy for stage II-III breast cancer treatment. 100 cases of eligible patients were diagnosed by core needle biopsy and immunohistochemistry, with the molecular subtypes of triple-negative, HER2+ or Luminal B, evaluated by pathological complete remission (pCR), objective response rate (ORR), adverse events, disease free survival (DFS) and OS, aiming at providing a new way for neoadjuvant therapy in breast cancer and anti-angiogenic treatment of malignant tumors.

Arm && Interventions

Group	Intervention	Description
apatinib+TP	paclitaxel	TP neoadjuvant chemotherapy (paclitaxel 165mg/m2 day 1, cisplatin 40mg, day 1-3) combined with apatinib (received TP concurrently with apatinib 500mg, day1-21).
apatinib+TP	Apatinib	TP neoadjuvant chemotherapy (paclitaxel 165mg/m2 day 1, cisplatin 40mg, day 1-3) combined with apatinib (received TP concurrently with apatinib 500mg, day1-21).
apatinib+TP	cisplatin	TP neoadjuvant chemotherapy (paclitaxel 165mg/m2 day 1, cisplatin 40mg, day 1-3) combined with apatinib (received TP concurrently with apatinib 500mg, day1-21).
TP	cisplatin	TP neoadjuvant chemotherapy alone (paclitaxel 165mg/m2 day 1, cisplatin 40mg, day 1-3).
TP	paclitaxel	TP neoadjuvant chemotherapy alone (paclitaxel 165mg/m2 day 1, cisplatin 40mg, day 1-3).

Primary Outcome Measures

Name	Time	Method
The primary endpoint is pathological complete remission (pCR)	4 months	pCR was defined as no histological evidence of invasive tumor cells in the surgical breast specimen and draining nodes. The presence of residual ductal carcinoma-in situ was not included in the pCR category after neoadjuvant treatment.

Secondary Outcome Measures

Name	Time	Method
The second endpoint includes the objective response rate (ORR)	4 months	Evaluation of tumor response was performed by independent evaluators who were blinded to the arm assignment consisted of 2 oncologists and 2 pathologists. Tumor response status was defined according to the Response Evaluation Criteria in Solid Tumors Committee (RECIST). Specifically, the complete response (CR) was defined as the disappearance of all the lesions both in breast specimen and draining nodes; The primary endpoint ORR composed of tumor response classifications of CR and partial response (PR).
Adverse events (AE)	4 months	Adverse events (AE) were monitored on an ongoing basis and classified according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), version 3.0. Patients were assessed for toxicities before each administration., and toxicity was graded accordingly.
