What is kesimpta made from?

What is Kesimpta (ofatumumab) made from?

Kesimpta’s active ingredient is ofatumumab, a monoclonal antibody. Monoclonal antibodies are made from living cells using biotechnology, where the antibody is produced as a protein biologic drug and then formulated for injection.

Is Kesimpta a pill made from chemicals or a biologic?

Kesimpta is a biologic (antibody) therapy, not a traditional small-molecule chemical tablet. That means it is manufactured as a protein drug (ofatumumab) rather than synthesized as a chemical.

What else might people mean by “made from” (inactive ingredients)?

People sometimes ask “made from” to mean the additional components in the injection besides the antibody. Those parts are typically formulation ingredients used to stabilize the protein and make the medicine suitable for dosing, but the key medicine itself is ofatumumab (the antibody).
