Study Details
Study Description
Brief Summary
This study will investigate the safety and efficacy of TIL therapy in patients with metastatic TNBC who have progressed on at least one and no more than three prior systemic anticancer therapies.

Phase 2 |
Detailed Description
The primary aims of the study are:
-
To evaluate the efficacy of autologous LN-145 as a single therapy in Metastatic Triple Negative Breast Cancer (TNBC) patients by determining the objective response rate (ORR), using the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, as assessed by the Investigator.
-
To characterize the safety profile of tumor infiltrating lymphocytes (TIL) as a single therapy in Metastatic Triple Negative Breast Cancer patients as measured by the incidence of Grade ≥ 3 treatment-emergent adverse events (TEAEs).
The secondary aims of the study are:
• To further evaluate the efficacy of autologous LN-145 as a single therapy in Metastatic Triple Negative Breast Cancer patients using complete response duration of response (DOR), disease control rate (DCR), and progression-free survival (PFS), using RECIST 1.1, as assessed by the Investigator, overall survival (OS) and (CR) rate.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: LN-145 LN-145 will be delivered as a single therapy in patients with Metastatic Triple Negative Breast Cancer. |
Drug: Tumor infiltrating lymphocytes (TIL) LN-145
The TIL autologous therapy with LN-145 is comprised of the following steps:
Tumor resection to provide the autologous tissue that serves as the source of the TIL cellular product;
LN-145 investigational product production at a central Good Manufacturing Practice (GMP) facility;
A 7-day nonmyeloablative lymphodepletion (NMA-LD) preconditioning regimen (hospitalization per institution standards);
Infusion of the autologous LN-145 product on Day 0 (during inpatient hospitalization);
Intravenous (IV) interleukin-2 (IL-2) administrations for up to six doses maximum (during inpatient hospitalization).
