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


Sponsor

Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University

Enrollment

196 participants

Start Date

Aug 1, 2023

Study Type

INTERVENTIONAL

Conditions

Summary

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.

Plain Language Summary

Simplified for easier understanding

This study is testing a personalized immune cell therapy as a pre-surgery treatment (neoadjuvant) for women with HER2-negative breast cancer. Immune cells from lymph nodes near the tumor are harvested, multiplied in a lab, and infused back to help shrink the tumor before surgery. **You may be eligible if:** - You are a woman aged 18–70 - You have invasive HER2-negative breast cancer confirmed by needle biopsy - Your tumor is at least 1 cm and has not spread to distant organs - You have already received two cycles of standard chemotherapy (doxorubicin/epirubicin plus cyclophosphamide) and had stable disease - You have not received any other prior treatment for breast cancer **You may NOT be eligible if:** - You have previously had chemotherapy, radiation, hormonal therapy, or surgery for breast cancer (except the two qualifying chemo cycles) - Your lymph nodes near the tumor have already been removed - You are pregnant or breastfeeding Talk to your doctor to see if this trial is right for you.

Interventions

PROCEDURESentinel Lymph Node Biopsy (SLNB)

A sample of the participant's tumor-draining lymph nodes will be collected and sent to the biotherapy center for LNL isolation and expansion.

DRUGDoxorubicin

Doxorubicin will be administered at 60 mg/m\^2 IV on Day 1 of Cycles 1-2 of the neoadjuvant chemotherapy of the study.

DRUGEpirubicin

Epirubicin will be administered at 100 mg/m\^2 IV on Day 1 of Cycles 1-2 of the neoadjuvant chemotherapy of the study.

DRUGCyclophosphamide

Cyclophosphamide will be administered at 600 mg/m\^2 IV on Day 1 of Cycles 1-2 of the neoadjuvant chemotherapy of the study.

DRUGCyclophosphamide

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.

DRUGFludarabine

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.

BIOLOGICALTumor-draining lymph node-derived lymphocyte (LNL)

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.

BIOLOGICALInterleukin-2

Eight to twelve hours after completing the LNL infusion, all participants will receive intermediate-dose decrescendo IL-2 IV.

DRUGNab-paclitaxel

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.
