NCT05981014

Brief 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.

Outcome Measures

Primary Outcomes (3)

  • Phase I: Incidence of Dose-Limiting Toxicity (DLT)

    Adverse events are reported based upon Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 criteria. DLT will be defined as a non-hematologic Grade 3 or higher adverse event, occurring within the 28 days immediately after LNL infusion, that is probably or definitely related to LNL infusion, and lasts more than 28 days or does not resolve to Grade\<3 despite treatment with dexamethasone at 10 mg per 12 hours IV for 7 days (or other corticosteroid at equivalent dose), and/or tocilizumab at 8mg/kg IV for three times.

    From the LNL infusion up to 28 days post-infusion

  • Phase I: Incidence of Grade≥3 Treatment-Emergent Adverse Event (TEAE)

    Adverse events are reported based upon CTCAE version 5.0 criteria. The incidence of Grade≥3 TEAE occurring within the 28 days immediately after LNL infusion will be summarized with descriptive statistics.

    From the LNL infusion up to 28 days post-infusion

  • Phase II: Pathological complete response (pCR) rate using the definition of ypT0/Tis ypN0 at the time of definitive surgery

    pCR rate (ypT0/Tis ypN0) is defined as the percentage of participants without residual invasive cancer on hematoxylin and eosin evaluation of the complete resected breast specimen and all sampled regional lymph nodes following completion of neoadjuvant systemic therapy assessed by the local pathologist at the time of definitive surgery.

    Up to approximately 18~29 weeks

Secondary Outcomes (8)

  • Phase I: Pathological complete response (pCR) rate using the definition of ypT0/Tis ypN0 at the time of definitive surgery

    Up to approximately 26~29 weeks

  • Phase I and phase II: Objective Response Rate (ORR)

    Up to approximately 26~29 weeks

  • Phase I and phase II: 6-month, 1-year and 2-year Event-Free Survival (EFS)

    Up to approximately two years

  • Phase I and phase II: Overall Survival (OS)

    Up to approximately five years

  • Phase I: Levels of multiple different cytokines in blood samples before and after LNL infusion.

    Up to approximately two years

  • +3 more secondary outcomes

Study Arms (2)

Phase I and phase II: Chemotherapy + LNL treatment

EXPERIMENTAL

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.

Procedure: Sentinel Lymph Node Biopsy (SLNB)Drug: DoxorubicinDrug: EpirubicinDrug: CyclophosphamideDrug: FludarabineBiological: Tumor-draining lymph node-derived lymphocyte (LNL)Biological: Interleukin-2Drug: Nab-paclitaxel

Phase II: Chemotherapy

ACTIVE COMPARATOR

The single-arm phase I study did not have this arm. Participants in phase II portion receive two cycles of doxorubicin or epirubicin, plus cyclophosphamide (AC or EC), followed by 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.

Drug: DoxorubicinDrug: EpirubicinDrug: CyclophosphamideDrug: Nab-paclitaxel

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

Also known as: SLNB
Phase I and phase II: Chemotherapy + LNL treatment

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

Phase I and phase II: Chemotherapy + LNL treatmentPhase II: Chemotherapy

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

Phase I and phase II: Chemotherapy + LNL treatmentPhase II: Chemotherapy

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

Phase I and phase II: Chemotherapy + LNL treatmentPhase II: Chemotherapy

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.

Phase I and phase II: Chemotherapy + LNL treatment

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.

Also known as: LNL

Also known as: IL-2
Phase I and phase II: Chemotherapy + LNL treatment

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.
