Biological: Individual Patient TCR Transduced PBL Drug: Cyclophosphamide Drug: Fludarabine Drug: Aldesleukin Drug: Pembrolizumab |
Background:
Please refer to National Cancer Institute Surgery Branch (NCI-SB) protocol 18-C-0049, Amendment F.
Objective:
Under Individual Patient Expanded Access, to treat a patient with metastatic prostate cancer with autologous peripheral blood lymphocytes (PBL) that have been transduced with genes encoding T-cell receptors that recognize the mutated TP53 shared oncogene in the autologous cancer.
Eligibility:
- Must have measurable, metastatic disease as assessed per RECIST v1.1 criteria.
- Must sign the informed consent document.
- Willing to sign Durable Power of Attorney Form.
- Must have all regulatory approvals prior to start of treatment.
Design:
- Please refer to NCI-SB protocol 18-C-0049, Amendment F.
- The patient will be treated with a non-myeloablative, lymphodepleting preparative regimen of cyclophosphamide and fludarabine, followed by the infusion of autologous transduced PBL and then high-dose aldesleukin. The patient will also receive pembrolizumab on Day -2 prior to cell administration and additional doses every 3 weeks following cell infusion until the time of disease progression.

Official Title: | Single Patient Protocol: A Phase II Study Using the Administration of Autologous T-Cells Genetically Engineered to Express T-Cell Receptors Reactive Against Mutated Neoantigens in a Patient With Metastatic Cancer Plus the Administration of Pembrolizumab |

- Biological: Individual Patient TCR Transduced PBL
Day 0: Cells will be infused at a dose not to exceed .5e11 in 400 mL IV on the Patient Care Unit over 20-30 minutes (2-4 days after the last dose of fludarabine).
- Drug: Cyclophosphamide
Days -7 and -6: Cyclophosphamide 60 mg/kg/day x 2 days IV in 250 mL D5W infused simultaneously with mesna 15 mg/kg/day over 1 hour x 2 days.
- Drug: Fludarabine
Days -7 to -3: Fludarabine 25 mg/m2 /day IVPB daily over 30 minutes for 5 days.
- Drug: Aldesleukin
Aldesleukin 720,000 IU/kg IV (based on total body weight) over 15 minutes every eight hours (+/- 1 hour) beginning within 24 hours of cell infusion and continuing for up to 4 days (maximum 10 doses).
- Drug: Pembrolizumab
Pembrolizumab 2 mg /kg IV over approximately 30 minutes on Day -2 and then every 3 weeks until time of disease progression.
