Summary

This trial tests a new treatment for patients with hard-to-treat or recurring osteosarcoma. It uses a special drug and modified immune cells to target and kill cancer cells. The patient's own immune cells are changed in a lab to better recognize cancer, and a drug helps these cells find and destroy the cancer.

Who is the study for?
This trial is for patients with osteosarcoma that's resistant to treatment or has returned. Participants must have a new site of disease confirmed by imaging, be able to undergo apheresis, and have a life expectancy of at least 8 weeks. They should not have HIV or hepatitis, agree to use contraception if applicable, and have good organ function. Exclusions include active severe infections, other cancers, primary immunodeficiency syndrome, pregnancy/breastfeeding, and any condition preventing protocol adherence.
What is being tested?
The study tests UB-TT170 combined with modified CAR T cells against osteosarcoma. Patients' T cells are collected and engineered in the lab to target cancer flagged by UB-TT170. After chemotherapy preparation, these CAR T cells are infused back into the patient followed by regular doses of UB-TT170 to mark cancer cells for destruction by CAR T cells.
What are the potential side effects?
Potential side effects may include reactions from cell infusion like fever or fatigue; complications from chemotherapy such as nausea; immune responses where the body attacks its own tissues; increased risk of infection due to weakened immunity; and possible long-term effects which will be monitored over 15 years.

Study Objectives

Study objectives can provide a clearer picture of what you can expect from a treatment.
Primary study objectives
Adverse events associated with ex-vivo expanded autologous T cells genetically modified to express an antiFL(FITC-E2) CAR administered with UB-TT170 will be assessed
Secondary study objectives
Ability to manufacture antiFL(FITC-E2) CAR cells
Evaluate the pharmacokinetics of UB-TT170 in combination with the anti-FL(FITC-E2) CAR T cells

Trial Design

1Treatment groups
Experimental Treatment
Group I: UB-TT170 following SCRI-E2CAR_EGFrtv1Experimental Treatment2 Interventions
Following CAR T cell administration, subjects will receive a first Course of 3 escalating doses of UB-TT170 over 2 weeks followed by fixed weekly dosing for 2 weeks. If eligible, subjects may proceed to Courses 2 - 4 consisting of 7 weekly doses of UB-TT170.

Other Research
Traditional treatments for osteosarcoma typically include surgery, chemotherapy, and radiation therapy. Chemotherapy uses drugs to kill rapidly dividing cancer cells, while surgery aims to remove the tumor physically. Radiation therapy uses high-energy rays to destroy cancer cells. The novel treatment involving UB-TT170 and CAR T cells represents a significant advancement. UB-TT170 flags the tumor cells, making them recognizable to the genetically modified CAR T cells, which then target and kill these flagged cells. This targeted approach can potentially improve treatment efficacy and reduce side effects compared to conventional therapies, offering new hope for patients with refractory or recurrent osteosarcoma.
