    Characterization of TKI-induced drug-tolerant persister cells from a patient-derived cell line (AACR 2023)
    The model is a non-small cell lung cancer harboring EML4-ALK fusion and ALK C1156Y/G1269A mutation, sensitive to the 3rd generation ALK TKI lorlatinib... We demonstrated potential targetable features of DTP cells. A combination of targeted therapies with DTP drug candidates could represent a therapeutic opportunity to improve the depth of response and delay the emergence of resistance in patients.

    [VIRTUAL] Patient-derived lung cancer organoids for the selection of therapeutic options in an ALK-rearranged tumor. (ASCO 2021)
    One patient was deemed as sensitive to carboplatin but tumor showed to be resistant...The patient started alectinib but showed progression after 12 months...Treatment was switched to brigatinib with no response...The In vitro results demonstrated no activity of lorlatinib but a strong response to crizotinib... We present clinical evidence that PDOs are an alternative tool in oncogenic addicted tumors helping to guide treatment decisions and increasing a more personalized sequential treatment approach.
