Patient information: uses, side effects, how to take - Columvi

What is the most important information I should know about COLUMVI?

COLUMVI can cause serious side effects, including:

Cytokine Release Syndrome (CRS). CRS is a serious side effect that is common during treatment with COLUMVI and can lead to death. Tell your healthcare provider or get medical help right away if you develop any signs or symptoms of CRS, including:

  • fever of 100.4°F (38°C) or higher
  • chills or shaking
  • fast or irregular heartbeat
  • dizziness or light-headedness
  • trouble breathing
  • shortness of breath

Due to the risk of CRS, you will receive COLUMVI on a "step-up dosing schedule".

  • The "step-up dosing schedule" is when you receive smaller "step-up" doses of COLUMVI to help reduce your risk of CRS.
  • You will receive a medicine called obinutuzumab on the first day of your first treatment cycle (Day 1 of Cycle 1). You will start the COLUMVI "step-up dosing schedule" a week after the obinutuzumab dose.
  • You will receive smaller "step-up" doses of COLUMVI on Day 8 and Day 15 of Cycle 1.
  • You will receive your first full dose of COLUMVI a week after the second "step-up" dose (this will be Day 1 of Cycle 2).
  • Before each dose of COLUMVI, you will receive medicines to help reduce your risk of CRS and infusion-related reactions.

  • You should be hospitalized during your infusion and for 24 hours:

    • after receiving the first "step-up" dose on Day 8 of Cycle 1.
    • after receiving the second "step-up dose" on Day 15 of Cycle 1, if you experienced CRS during the first "step-up" dose.
    • if you had more than mild CRS with your previous dose of COLUMVI.
  • If your dose of COLUMVI is delayed for any reason, you may need to repeat the "step-up dosing schedule".
  • Your healthcare provider will monitor you for CRS during treatment with COLUMVI and may treat you in a hospital if you develop signs and symptoms of CRS.
  • See "How will I receive COLUMVI?" for more information about how you will receive COLUMVI.
  • Your healthcare provider may temporarily stop or completely stop your treatment with COLUMVI if you have severe side effects.
  • Carry the COLUMVI Patient Wallet Card with you at all times and show it to all of your healthcare providers. The COLUMVI Patient Wallet Card lists the signs and symptoms of CRS that you should get medical help for right away.

See "What are the possible side effects of COLUMVI? " for more information about side effects.
