My husband received CAR-T treatment on 5/21. He was then offered an opportunity to participate in a clinical trial using Cevostamab as maintenance follow up to CAR-T. He began this on 7/20. He has had two doses with the step up dosing being used. Thus, he has only had one full dose. After the full dose, he developed a small cough which remains today. One week after the full dose, he developed a full body rash. Has anyone else taking Cevostamab had a similar experience with cough and delayed rash?
