Frequently asked questions about Odronextamab

What is Odronextamab used for?

Odronextamab is an investigational small molecule being studied for the treatment of B-cell Non Hodgkin Lymphoma. It is currently in Phase 2 clinical development and is not yet approved by regulatory authorities. The drug is being evaluated in patients with relapsed and refractory disease.

What does Odronextamab target?

Odronextamab targets MS4A1, CD3E, CD3G, and CD3D. MS4A1 is a B-cell surface antigen, while the CD3 molecules are part of the T-cell receptor complex. This binding agent is designed to engage both B-cells and T-cells in the context of B-cell Non Hodgkin Lymphoma.

Who is developing Odronextamab?

Odronextamab is being developed by ADC Therapeutics SA, a biopharmaceutical company traded under the ticker ADCT. The company is conducting clinical trials to evaluate the drug's safety and efficacy in patients with B-cell Non Hodgkin Lymphoma.

What phase is Odronextamab in?

Odronextamab is in Phase 2 clinical development. It is an investigational drug, meaning it has not been approved by the FDA or other regulatory agencies. The ongoing Phase 2 trial is actively recruiting participants to assess the drug's effects in the intended patient population.

What clinical trials is Odronextamab in?

Odronextamab is being evaluated in a Phase 2 clinical trial registered as NCT05991388. This study is titled 'A Global Study of Novel Agents in Paediatric and Adolescent Relapsed and Refractory B-cell Non-Hodgkin Lymphoma' and is currently recruiting participants across multiple countries including Australia, Austria, Belgium, the Netherlands, New Zealand, Sweden, and the United Kingdom.
