Summary

Prof. Ronit Satchi-Fainaro presents her lab’s work on developing 3D-printed tumor models to improve drug development and personalized medicine. She highlights the high attrition rate in oncology drug development, attributing it to inadequate preclinical models. Her lab creates patient-derived 3D-printed tumors with perfusable blood vessels and immune cells, allowing for testing of nanomedicines and immunotherapies. They use these models to identify P-selectin as a target in brain malignancies, showing its overexpression in tumor-associated microglia. They develop P-selectin-targeted nanoparticles for drug delivery and a P-selectin inhibitor, demonstrating efficacy in preclinical models. The talk concludes with a case of a patient with brain metastasis who responded to an anti-P-selectin antibody, illustrating the translational potential.

Critical Evaluation

Value of the Information & Strength of the Argument

The talk provides valuable insights into the limitations of current cancer models and presents a compelling case for 3D-printed models as a more clinically relevant alternative. The argumentation is strong, supported by data from their own studies and references to published work. The speaker effectively demonstrates the utility of their platform for drug testing and target discovery, with clear examples of how it led to the identification of P-selectin as a target.

Scientific Rigor, Source Quality, Title Accuracy

The speaker references several of her own publications and mentions the FDA Modernization Act 2.0. She also mentions a clinical trial with 80 patients and a patient treated with an anti-P-selectin antibody. However, specific citations are not provided in the talk. The title accurately reflects the content, focusing on P-selectin targeting in brain tumors and its combination with immune checkpoint modulators.
