I would be surprised if there were no responses to SENTI-202, but complete remission has long been the critical therapeutic response, ideally MRD-negative. Toxicity is another, as cytarabine (used for lymphodepletion with fludarabine) has potent immunosuppressive effects so that could lead to (additional) myelosuppression and infections. A third will be how well the logic-gated gene circuit (for the CARs) protects healthy hematopoietic stem cells.
