Out of 28 patients, three had p53 mutations did not respond to treatment or relapsed whereas the rest responded to treatment. Patients who received at least six months of treatment are currently in molecular remission. A further study incorporating a bispecific antibody to the aforementioned treatment regimen for patients with P53 mutations is also planned.
