Official title
A Phase Ib Open-Label Study of LB-100 in Combination With Carboplatin/Etoposide/Atezolizumab in Untreated Extensive-Stage Small Cell Lung Carcinoma
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This phase Ib trial studies the side effects and best dose of LB-100 when given together with carboplatin, etoposide, and atezolizumab for the treatment of untreated extensive-stage small cell lung cancer. Drugs such as carboplatin and etoposide work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. 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. LB-100 has been shown to make anticancer drugs (chemotherapy) work better at killing cancer. LB-100 blocks a protein on the surface of cells called PP2A. Blocking this protein makes the tumor cells that express PP2A divide. This allows standard chemotherapy drugs such as carboplatin, etoposide, and atezolizumab work better at killing the tumor cells since these drugs work best at destroying cells that are dividing. Giving LB-100 in combination with standard chemotherapy drugs may work better to treat extensive-stage small cell lung cancer compared to standard chemotherapy drugs alone.
