ality and we let it learn from past actions. We use a heuristic that is well-known in Artificial Intelligence: the Monte-Carlo Tree Search. What we are looking for:
We run an in-silico clinical trial, where we compare our optimal protocols to the standard protocol (Maximum Tolerated Dose, MTD). Results are twofold:
• we have a convincing Proof of Concept on retrospective data; Ex-ante optimized, unpersonalized protocol:
• our concept has been applied to other problems: immunotherapy, drug combination, EPO;
• efficacy is greatly improved: the tumor size at day 336 is divided by
• we are looking for partners to go beyond the Proof of Concept.
more than 6; • toxicity is not deteriorated: a smaller number of patients experience a severe toxicity.
