Teclistamab Teclistamab (Tecvalyi)

Teclistamab (Tecvayli) is an immunotherapy medication used to treat multiple myeloma, a cancer of the plasma cells. It works as a bridge that connects your body’s own immune cells directly to myeloma cells, allowing your immune system to recognize and clear them. Because this therapy can cause specific immune-related side effects, understanding how it affects your body helps you plan your daily routine and clinic visits. Here, you can learn what to expect during treatment, find practical ways to manage side effects, and share experiences with other patients and caregivers.
