Data at ASH on 3 December confirmed that CYAD-01 T-cells can destroy acute myeloid leukaemia (AML) blast (cancer) cells. In eight reported AML patients, there was a 62% (5/8) response rate across three dose levels. As preconditioning was not used, this rate is impressive. Safety was excellent with only one dose-limiting toxicity event at a high dose. The good safety profile should now enable faster progress to determine the optimal dose schedule. Further data are promised in H119, probably mid-year. A study combining CYAD-01 with preconditioning is underway and may be crucial. The indicative value is still €1,090m (€89 per share) pending further data.
