Clinical trial for Metastatic Malignant Solid Neoplasm
Official title Gene Modified Immune Cells After Conditioning Regimen for the Treatment of Stage IIIC or IV Melanoma or Metastatic Solid Tumors
ClinicalTrials.gov ID: NCT04119024
What this study is testing
What is Cyclophosphamide?
Cyclophosphamide is an investigational chemotherapy drug being studied as part of a conditioning regimen for metastatic malignant solid neoplasms. It is designed to suppress the patient's immune system and create space for the infused CAR T cells to expand.
Also referred to as Cytoxan, CP, CTX, Cyclophosphamide Monohydrate.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The study aims to find the safest dose of the modified cells, see how long they stay in the body, and learn whether they can attack the cancer.
- Who it's for
- Adults who have stage IIIC or IV melanoma or other cancers that have spread to other parts of the body.
- What's involved
- Your own blood T cells are collected, engineered in a lab to carry a special gene, and then infused back after a short chemotherapy conditioning. You will have regular clinic visits for safety checks, blood tests, and imaging.
- Time commitment
- The trial lasts several months and includes multiple visits for treatment, monitoring, and follow‑up assessments.
- Phase 1: an early, usually small safety study
