Mosunetuzumab

I have NHFL grade 3a stage 4. No symptoms and I got into a clinical trial at city of Hope for Mosunetuzumab. I just finished my 4 injection. The first one was 5mg then the rest will be 45mg. This past Wednesday was my 4th treatment and now it will be every 21 days till late August. I have a mid way PET scan scheduled for mid March and then the final PET at the end of August. Did anyone here do only Mosunetuzumab and if so how did it go and what were your results? Thank you and I hope it makes sense.
