A Trial to Learn How Well Linvoseltamab Works Compared to the Combination of Elotuzumab, Pomalidomide and Dexamethasone for Adult Participants With Relapsed/Refractory Multiple Myeloma
Recruiting
This study is researching an experimental drug called linvoseltamab, also called REGN5458.

Efficacy and Safety of Phentermine/Topiramate in Youth With Hypothalamic Obesity
Recruiting
Hypothalamic obesity (HO) refers to the substantial weight gain that often complicates hypothalamic brain tumors. Children with this treatment-recalcitrant form of obesity have excess rates of metabolic sequelae compared to otherwise healthy children with similar obesity, and later experience excess mortality related to cardiometabolic disease. In this pilot trial, our objective is to gather key preliminary data about phentermine/topiramate (Ph/T) that is FDA-approved for "common" obesity but ha... Read More

A Study Comparing Venetoclax and Azacitidine Plus Cusatuzumab to Venetoclax and Azacitidine in Newly Diagnosed AML Ineligible for Intensive Therapy
Recruiting
The goal of this clinical trial is to learn if participants treated with the experimental drug cusatuzumab added to venetoclax and azacitidine works to treat acute myeloid leukemia (AML) compared to venetoclax and azacitidine. Venetoclax and azacitidine are drugs commonly used to treat AML in patients that are unable to receive chemotherapy to treat AML.
