Summary

This trialtests combining 2 monoclonal antibodies to see if it can kill more cancer cells in untreated CLL.

Who is the study for?
This trial is for adults with untreated chronic lymphocytic leukemia (CLL) who need treatment due to symptoms or blood abnormalities. They must be in good enough health to participate, not have other active cancers except certain skin cancers or localized breast/cervical cancer, and can't have serious heart conditions, hepatitis B or C, HIV, recent strokes, or uncontrolled medical issues.
What is being tested?
The study tests the combination of two monoclonal antibodies—alemtuzumab and ofatumumab—in patients with CLL. These drugs are designed to target cancer cells by blocking their growth and helping the immune system destroy them. The trial aims to see how well these drugs work together when given for the first time to those with CLL.
What are the potential side effects?
Potential side effects include infusion reactions where the drug enters the body, weakened immunity leading to infections, allergic responses specific to each drug's components, possible anemia from bone marrow suppression by alemtuzumab and ofatumumab as they attack cancerous white blood cells.
