- 97% of patients benefited during the first six months, and after about three years, 93% were still alive.
- Some patients had long-lasting responses, with one on the treatment for over six years.
- Side effects included low white blood cell counts, diarrhea, and anemia, but only one patient stopped treatment due to side effects.
