Study of Autologous Tumor-Draining Lymph Node-Derived Lymphocytes as Neoadjuvant Therapy for HER2-Negative Breast Cancer
An Open-Label Phase I/II Study of Autologous Tumor-Draining Lymph Node-Derived Lymphocytes as Neoadjuvant Therapy for HER2-Negative Breast Cancer
RATIONALE: Patients with HER2-negative breast cancer not responding to initial neoadjuvant chemotherapy might have lower chances for a pathologic complete response (pCR) at definitive surgery, indicating worse prognosis. Adoptive cell therapy has demonstrated efficacy in advanced breast cancer, but whether the addition of adoptive cell therapy to neoadjuvant chemotherapy could increase the pCR rate remains unclear. Tumor-draining lymph node-derived lymphocytes (LNLs) that have abundant tumor-reactive T cells, but not exhausted T cells, are easy to produce. It is not yet known whether LNL treatment is safe and effective in patients with HER2-negative breast cancer not responding to neoadjuvant chemotherapy.
PURPOSE: This open-label phase I/II trial is to investigate the safety and efficacy of autologous LNL in patients with HER2-negative breast cancer not responding to neoadjuvant chemotherapy.

Intervention / Treatment |
---|---|
Experimental: Phase I and phase II: Chemotherapy + LNL treatment
Participants in both phase I and phase II portions receive two cycles of doxorubicin or epirubicin, plus cyclophosphamide (AC or EC), followed by neoadjuvant LNL treatment, which consists of non-myeloablative lymphocyte depleting regimen of chemotherapy with cyclophosphamide and fludarabine, followed by infusion of LNL and interleukin-2.
After LNL treatment, participants receive four-cycles of nab-paclitaxel as neoadjuvant therapy prior to definitive surgery.
The choice of doxorubicin or epirubicin should be the same as the prior neoadjuvant chemotherapy.
|
A sample of the participant's tumor-draining lymph nodes will be collected and sent to the biotherapy center for LNL isolation and expansion.
Other Names:
Doxorubicin will be administered at 60 mg/m^2 IV on Day 1 of Cycles 1-2 of the neoadjuvant chemotherapy of the study.
Epirubicin will be administered at 100 mg/m^2 IV on Day 1 of Cycles 1-2 of the neoadjuvant chemotherapy of the study.
Cyclophosphamide will be administered at 600 mg/m^2 IV on Day 1 of Cycles 1-2 of the neoadjuvant chemotherapy of the study.
Cyclophosphamide will be administered at 60 mg/kg IV daily over approximately two hours for two days.
Cyclophosphamide will be initiated seven days prior to the anticipated LNL transfer, and the precise timing will depend on the rate of in vitro LNL growth.
After administration of cyclophosphamide, fludarabine will then be infused at 25 mg/m^2 intravenous piggyback (IVPB) daily over approximately 30 minutes for five days, starting five days prior to LNL transfer.
In the dose-escalation portion of phase I study, participants receive ascending dose (1×10^9~18×10^9), single Infusion of LNL on day 0. In the dose-expansion portion of phase I study, participants receive single infusion of LNL at the recommended phase 2 dose (RP2D). In the phase II study, participants receive single infusion of LNL at the RP2D.
Other Names:
Eight to twelve hours after completing the LNL infusion, all participants will receive intermediate-dose decrescendo IL-2 IV.
Other Names:
Nab-paclitaxel will be administered at 260 mg/m^2 IV on Day 1 of Cycles 3-6 of the neoadjuvant chemotherapy of the study.
