Study of Autologous Tumor-Draining Lymph Node-Derived Lymphocytes for Advanced HER2-Negative Breast Cancer
Study Details
Study Description
Brief Summary
RATIONALE: Patients with HER2-negative advanced breast cancer have limited choice on targeted therapies, and often show only modest responses to available immunotherapies. Adoptive cell therapy with tumor-infiltrating lymphocytes has difficulties in preparing enough cells from solid tumors and overcoming the exhaustion and dysfunction of T cells, which limit its clinical use. Tumor-draining lymph node-derived lymphocytes (LNLs) that have abundant tumor-specific T cells, rather than exhausted T cells, are easier to produce. It is not yet known whether LNL treatment is safe and effective in patients with advanced HER2-negative breast cancer.
PURPOSE: This open-label phase I/II trial is to study the safety and efficacy of autologous LNL in patients with advanced HER2-negative breast cancer.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Phase I and phase II: LNL treatment + Camrelizumab + Chemotherapy Participants in both phase I and phase II portions receive 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 camrelizumab PLUS one of two background chemotherapy regimens at investigator's discretion: (1) nab-paclitaxel, OR (2) gemcitabine/carboplatin. |
Procedure: Surgery for harvesting tumor-draining lymph nodes
A sample of the participant's tumor-draining lymph nodes will be collected and sent to the biotherapy center for LNL isolation and expansion.
Drug: Cyclophosphamide
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.
Drug: Fludarabine
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.
Biological: Tumor-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.
Other Names:
Biological: Interleukin-2
Eight to twelve hours after completing the LNL infusion, all participants will receive intermediate-dose decrescendo IL-2 IV.
Other Names:
Biological: Camrelizumab
Camrelizumab will be administered at a fixed dose of 200mg IV on Day 1 of each 21-day cycle until unacceptable toxic effects or disease progression or other termination criteria appeared.
Other Names:
Drug: Nab-paclitaxel
Nab-paclitaxel will be administered at 100 mg/m^2 IV on Days 1, 8 and 15 of each 28-day cycle until unacceptable toxic effects or disease progression or other termination criteria appeared.

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.
- Phase I: Incidence of Grade≥3 Treatment-Emergent Adverse Event (TEAE) [From the LNL infusion up to 28 days post-infusion]
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.
