A Trial to Find Out How Safe REGN7075 is and How Well it Works in Combination With Cemiplimab for Adult Participants With Advanced Cancers
Recruiting
This study is researching an investigational drug called REGN7075 by itself and in combination with cemiplimab with or without chemotherapy. The study is focused on patients with certain solid tumors that are in an advanced stage. The aim of the study is to see how safe and tolerable REGN7075 is by itself and in combination with cemiplimab (with or without chemotherapy), and to find out what is the best dose of REGN7075 to be given to patients with advanced solid tumors when combined with cemipl...

Bladder Fiducial Markers and Multiparametric-MRI (Mp-MRI) to Optimize Bladder Chemo-radiotherapy
Recruiting
The purpose of this study is to examine the usefulness of implanting small 24-K gold fiducial markers around a bladder tumor site, so that a Radiation Oncologist can identify the original tumor location at the time of radiation treatment. Other goals of the study include assessing whether a new MRI imaging technology can help with detection of bladder cancer earlier and more accurately when evidence of bladder cancer is not visible by scope.

Study to Test OBI-3424 in Patients With T-Cell Acute Lymphoblastic Leukemia (T-ALL) or T-Cell Lymphoblastic Lymphoma (T-LBL)
Recruiting
This phase I/II trial studies the safety, side effects and best dose of OBI-3424 and how well it works in treating patients with T-cell acute lymphoblastic leukemia or T-cell lymphoblastic lymphoma that has come back (relapsed) or does not respond to treatment (refractory). Chemotherapy drugs, such as OBI-3424, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. OBI-3424 may reduce the amount... Read More
