Frequently asked questions about Obinutuzumab

What is Obinutuzumab used for in Mantle-Cell Lymphoma?

Obinutuzumab is an investigational antibody being studied for the treatment of mantle-cell lymphoma, a type of non-Hodgkin lymphoma. It is currently in Phase 2 clinical development for this indication, with an ongoing trial evaluating its use in combination with other agents in high-risk mantle-cell lymphoma patients.

What does Obinutuzumab target?

Obinutuzumab is a monoclonal antibody, classified as a -mab (antibody) modality. It is designed to target CD20, a protein found on the surface of B-cells, which are the malignant cells in mantle-cell lymphoma. By binding to CD20, the antibody aims to direct the immune system to destroy these cancer cells.

Who is developing Obinutuzumab?

Obinutuzumab is being developed by BeOne Medicines Ltd., a biopharmaceutical company traded under the ticker symbol ONC. The company is conducting clinical trials to evaluate the drug's safety and efficacy in patients with mantle-cell lymphoma.

What phase is Obinutuzumab in?

Obinutuzumab is currently in Phase 2 clinical development. It is an investigational drug, meaning it has not yet been approved by regulatory authorities. The ongoing Phase 2 trial is actively recruiting participants to assess its potential as a treatment for high-risk mantle-cell lymphoma.

What clinical trials is Obinutuzumab in?

Obinutuzumab is being studied in a Phase 2 clinical trial registered as NCT06558604. This trial, titled 'Phase II Study of Glofitamab With Venetoclax +/- Zanubrutinib in High-risk Mantle-cell Lymphoma,' is recruiting 100 participants in Belgium and France. The study is controlled but not randomized or double-blinded, and it uses biomarker selection.

Is Obinutuzumab the same as Glofitamab?

No, Obinutuzumab is not the same as Glofitamab. Obinutuzumab is the drug being developed by BeOne Medicines Ltd. and is the subject of this profile. Glofitamab is a separate investigational agent that is being combined with other drugs in the clinical trial NCT06558604, which includes Obinutuzumab as part of the treatment regimen.
