Cryovivas take on the AUCB study

It is heartening to see KKH undertake this clinical trial in Singapore. One in 150 children in Singapore is reported to have this condition. Favourable results on the efficacy of umbilical cord blood infusion for the treatment of autism will be a huge boon to families in Singapore and a source of great hope to them. We eagerly await the complete results of this important trial and wish both KKH and all participants the very best.
