Venetoclax, MLN9708 (Ixazomib Citrate) and Dexamethasone for the Treatment of Relapsed or Refractory Light Chain Amyloidosis
Recruiting
This phase I/Ia trial finds the best dose and side effects of venetoclax given in combination with ixazomib citrate and dexamethasone in treating patients with light chain amyloidosis that has come back (relapsed) or does not respond to treatment (refractory) and who have an abnormal genetic change \[translocation t(11;14)\]. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer c... Read More

Tumor-agnostic Precision Immuno-oncology and Somatic Targeting Rational for You (TAPISTRY) Platform Study
Recruiting
TAPISTRY is a Phase II, global, multicenter, open-label, multi-cohort study designed to evaluate the safety and efficacy of targeted therapies or immunotherapy as single agents or in rational, specified combinations in participants with unresectable, locally advanced or metastatic solid tumors determined to harbor specific oncogenic genomic alterations or who are tumor mutational burden (TMB)-high as identified by a validated next-generation sequencing (NGS) assay. Participants with solid tumors... Read More

Comparing the New Anti-cancer Drug Eribulin With Chemotherapy Against the Usual Chemotherapy Alone in Metastatic Urothelial Cancer
Recruiting
This phase III trial compares the usual chemotherapy treatment to eribulin plus gemcitabine in treating patients with urothelial cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Chemotherapy drugs, such as eribulin, gemcitabine, docetaxel, paclitaxel, and sacituzumab govitecan 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. This tri... Read More

Testing the Addition of Radiation Therapy to the Usual Immune Therapy Treatment (Atezolizumab) for Extensive Stage Small Cell Lung Cancer, The RAPTOR Trial
Recruiting
This phase II/III trial compares the effect of adding radiation therapy to the usual maintenance therapy with atezolizumab versus atezolizumab alone in patients who have already received atezolizumab plus chemotherapy for the treatment of small cell lung cancer that has spread outside of the lung or to other parts of the body (extensive stage). Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability o... Read More

Osimertinib With or Without Bevacizumab as Initial Treatment for Patients With EGFR-Mutant Lung Cancer
Recruiting
This phase III trial compares the effect of bevacizumab and osimertinib combination vs. osimertinib alone for the treatment of non-small cell lung cancer that has spread outside of the lungs (stage IIIB-IV) and has a change (mutation) in a gene called EGFR. The EGFR protein is involved in cell signaling pathways that control cell division and survival. Sometimes, mutations in the EGFR gene cause EGFR proteins to be made in higher than normal amounts on some types of cancer cells. This causes can... Read More
