Glofitamab

Glofitamab is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Glofitamab rather than just read about it. In short: Glofitamab, sold under the brand name Columvi, is a bispecific monoclonal antibody used for the treatment of large B-cell lymphoma. It is a bispecific CD20-directed CD3 T-cell engager developed by Roche.

Key takeaways

Glofitamab belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Glofitamab to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Glofitamab from memory before moving on to harder problems.

Reference excerpt

Glofitamab, sold under the brand name Columvi, is a bispecific monoclonal antibody used for the treatment of large B-cell lymphoma. It is a bispecific CD20-directed CD3 T-cell engager developed by Roche. The most common side effects include cytokine release syndrome, muscle and bone pain, rash, and tiredness. It was approved for medical use in Canada in July 2023, in the United States in June 2023, and in the European Union in July 2023.

Medical uses Glofitamab is indicated for the treatment of adults with relapsed or refractory diffuse large B-cell lymphoma. Specifically it is indicated for the treatment of adults with certain types of diffuse large B-cell lymphoma or large B-cell lymphoma who have received at least two prior treatments that did not work or are no longer working.

Adverse effects The US Food and Drug Administration (FDA) label includes a boxed warning for serious or fatal cytokine release syndrome. A report in January 2026 from Genentech warned that Glofitamab causes the cytokine release syndrome at rates of 1 to 20% in different studies when used to treat patients with lymphomas.

History The FDA approved glofitamab based on evidence from a clinical trial NP30179 (NCT03075696) of 145 participants with large B-cell lymphoma who received at least one dose of glofitamab. The efficacy of glofitamab was assessed in 132 participants with de novo diffuse large B‑cell lymphoma, not otherwise specified (80%) or large B-cell lymphoma arising from follicular lymphoma (20%), who have received at least two prior lines of therapy and who received at least one dose of glofitamab. The trial was conducted at 32 sites in 13 of countries in Australia, Belgium, Canada, Czech Republic, Denmark, Spain, Finland, France, Italy, New Zealand, Poland, Taiwan, and the United States. The benefit and side effects of glofitamab were also evaluated in the clinical trial. All participants received glofitamab until the disease progressed or the side effects became too toxic.

Society and culture

Legal status In April 2023, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion, recommending the granting of a conditional marketing authorization for the medicinal product Columvi, intended for the treatment of diffuse large B‑cell lymphoma (DLBCL). The applicant for this medicinal product is Roche Registration GmbH. Glofitamab was approved for medical use in the European Union in July 2023.

Names Glofitamab is the international nonproprietary name.

Worked examples

Example 1 — a first encounter with Glofitamab

Start with the simplest possible case. Write down what Glofitamab claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Glofitamab before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Glofitamab ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Glofitamab

In research: Glofitamab appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Glofitamab in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Glofitamab is common in secondary-school and first-year university syllabi. It links to neighbouring topics Drugs developed by Genentech, Drugs developed by Hoffmann-La Roche, Immunomodulating drugs, so understanding it makes those chapters shorter.
In everyday life: Look for Glofitamab outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Glofitamab in simple terms?

Why does Glofitamab matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Glofitamab?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
