Theranostic monoclonal antibody 8H9, conjugated to to 131 iodine. The antibody 8H9 acts by targeting B7-H3 or CD276 receptors present on cancer cells, causing radiolabelled iodine to kill cancerous tumours.
Neuroblastoma represents about 10% of solid tumors in infants and children under the age of 15, with an annual incidence of about 1/70,000 in children in this class of age [1].

Trial or other data
Dec 20Y-mAbs Therapeutics announces preliminary efficacy results from its pivotal PII/III 101 trial in patients with CNS/leptomeningeal metastasis from neuroblastoma. Overall survival was 75% after a period of 18 months. An additional independent radiographic evaluation of the tumour responses showed that for ten evaluable patients with measureable disease, a total of 40% of the patients responded to omburtamab, 20% with complete response (CR) and 20% with partial response (PR), and another five patients had stable disease (SD). All nine patients with response or SD maintained these at six months follow up. The study results were supportive of the conclusion from an earlier Study 03-133 [9].
Sep 20PII/III trial (101; NCT03275402) continues to recruit and collection of primary outcome data now expected Dec 20 [8].
Aug 19PII/III trial (NCT03275402) is recruiting; timescales unchanged [5].
Mar 19Y-mABs believes that the European market is at least one and a half times the size of the US market and that there are approximately 1,050 patients diagnosed with NB in Europe each year. The current addressable market for omburtamab, consists of approximately 200 new patients each year with CNS/LM from NB in the US and Europe, combined [4].
Oct 18PII/III trial to evaluate the efficacy and safety of intracerebroventricular 131I-omburtamab in patients with neuroblastoma of age up to 18 years starts (101; NCT03275402). Evaluation of the overall survival rate is the defined primary endpoint of the trial. The open label trial is presently enrolling approximately 32 patients in the US, Denmark and Spain. Collection of primary outcome data is expected to complete Dec 19 [2].
