New treatment option for Locally Advanced Osteosarcoma
Official title Atezolizumab and Cabozantinib for the Treatment of Adolescents and Young Adults With Recurrent or Metastatic Osteosarcoma, TACOS Study
ClinicalTrials.gov ID: NCT05019703
What this study is testing
What is Atezolizumab?
Atezolizumab is an investigational medicine, given as an once-daily infusion into a vein, being studied as a potential treatment for locally advanced osteosarcoma.
Also referred to as MPDL 3280A, MPDL 328OA.
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
- This phase II trial studies the effect of atezolizumab and cabozantinib in treating adolescents and young adults with osteosarcoma that has come back (recurrent) or has spread to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
- Phase 2: a mid-size study of how well it works
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
