It usually responds well to therapy but often comes back after periods of remission, which is difficult to treat after each relapse.
Lunsumio Velo is a lab-made bispecific antibody that uses the body’s own immune system to attack the cancer cells.
The medicine has two targets on immune cells: CD20 on B cells and CD3 on T cells. By binding to both, it brings the patient’s own T cells into contact with cancerous B cells, helping the T cells attack and kill the harmful B cells. This approval matters as unlike the original IV form that was given through a vein and took two to four hours to complete, the subcutaneous (SC) version of Lunsumio is injected under the skin and takes about a minute to give. As FL often requires lifelong management, the SC form offers a convenient, quicker, and less invasive method that may help you spend less time at the clinic, making it easier for you to continue with your treatment plan.
Why Was It Approved?
The FDA granted accelerated approval to Lunsumio Velo based on primary analysis of clinical studies that showed strong results in adults with relapsed or refractory FL after a minimum of two therapies. The treatment will get full approval after future studies confirm its helpful effects in patients with FL. In people with FL that had returned or stopped responding after at least two treatments, about 75% responded to the medicine, and nearly 59% had no signs of cancer after treatment. On average, those who responded stayed in remission for about 22.4 months.
What Do I Need to Know?
Lunsumio Velo is given as an injection under the skin in your stomach area (abdomen) or thigh by your health care provider who uses a step-up dosing schedule. This means you’ll start with smaller doses before moving to higher ones. This approach helps lower the risk of CRS. If your Lunsumio Velo dose is delayed, you may need to repeat the step-up doses. The medicine is usually given once every three weeks (21 days), and treatment can last from eight to 17 cycles, depending on how you respond. Before each dose (especially during the first cycle), you’ll likely get preventive medicines such as steroids and fever reducers to help you avoid side effects. Only trained health care providers should give this medicine, and they should be ready to manage serious reactions such as CRS or nerve problems. You’ll be closely watched during the first few doses to catch any early signs of side effects. Inform your health care provider if you have an infection or are getting treated for it, or have an infection that doesn’t go away or keeps coming back. Be sure to tell your provider if you’ve had the Epstein-Barr virus, an infusion reaction, or any other health issues before starting treatment. Lunsumio Velo may not be safe if you have certain immune system issues or have had serious reactions to similar treatments in the past. If you feel dizzy, confused, or very sleepy, avoid driving or using heavy machines until you feel better. Tell your health care provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, herbal remedies, and health supplements.
