New Clinical Trial: Atezolizumab and Bevacizumab in Treating Patients With Rare Solid Tumors (NCT03074513)

WHY IT MATTERS

This trial offers patients with rare cancers like Merkel cell carcinoma, nasopharyngeal cancer, and mesothelioma access to a combination immunotherapy treatment that may not be available outside of clinical research.

Researchers are testing whether two cancer-fighting drugs called atezolizumab and bevacizumab work better together for treating rare cancers. These drugs help the body's immune system recognize and attack cancer cells. The study includes 133 patients with various uncommon solid tumors and is currently enrolling participants.

NCT ID: NCT03074513 Status: ACTIVE_NOT_RECRUITING Conditions: Appendix Adenocarcinoma, Human Papillomavirus-Related Anal Squamous Cell Carcinoma, Human Papillomavirus-Related Cervical Squamous Cell Carcinoma, Human Papillomavirus-Related Squamous Cell Carcinoma of the Penis, Human Papillomavirus-Related Vulvar Squamous Cell Carcinoma, Neuroendocrine Carcinoma, Pancreatic Neuroendocrine Tumor, Recurrent Merkel Cell Carcinoma, Recurrent Nasopharynx Carcinoma, Recurrent Peritoneal Malignant Mesothelioma, Recurrent Pleural Malignant Mesothelioma, Stage III Merkel Cell Carcinoma AJCC v7, Stage III Nasopharyngeal Carcinoma AJCC v7, Stage III Pleural Malignant Mesothelioma AJCC v7, Stage IV Merkel Cell Carcinoma AJCC v7, Stage IV Nasopharyngeal Carcinoma AJCC v7, Stage IV Pleural Malignant Mesothelioma AJCC v7, Stage IVA Nasopharyngeal Carcinoma AJCC v7, Stage IVB Nasopharyngeal Carcinoma AJCC v7, Stage IVC Nasopharyngeal Carcinoma AJCC v7, Vaginal Squamous Cell Carcinoma, Not Otherwise Specified Phase: PHASE2 Enrollment: 133 Sponsor: M.D. Anderson Cancer Center Summary: This phase II trial studies how well atezolizumab and bevacizumab work in treating patients with rare solid tumors. Immunotherapy with monoclonal antibodies, such as atezolizumab and bevacizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

ASK YOUR DOCTOR

If you have one of the listed rare cancers, ask your oncologist whether you meet the eligibility criteria for this trial at M.D. Anderson Cancer Center or if similar combination immunotherapy approaches are appropriate for your specific diagnosis.
