AIC100 is received as a single infusion two days after completing lymphodepletion with Fludarabine/Cyclophosphamide. AIC100 demonstrated an excellent safety profile in DL1/DL2 treated patients with ATC and PDTC with no DLTs observed. The objective and relatively durable partial response in the first evaluable patient in the DL2, a patient with metastatic ATC who failed multiple lines of therapy, is unprecedented and very encouraging. Further investigations of AIC100 are ongoing at DL2 and DL3 to determine the RP2D.

The CAR T cells are engineered to co-express somatostatin receptor 2 (SSTR2), which allows for the tracking of CAR T cells in vivo via PET/CT scan using FDA-approved DOTATATE. AIC100 was generated by affinity tuning the I-domain of LFA-1, the physiological ligand to ICAM-1... We have developed affinity tuned CAR T cells designed to selectively target ICAM-1 overexpressing tumor cells and to spatiotemporally image CAR T cells. Near-synchronous FDG and DOTATATE scans will enhance patient safety by early detection of off-tumor CAR T activity and validation of tumor response. We anticipate that our “tune and track” technology will be widely applicable to developing potent yet safe CAR T cells against hard-to-treat solid cancers.
AIC1010 CAR T cells demonstrate superior cancer elimination compared to AIC100 CAR T cells in subcutaneous and IP tumor models in mice. We anticipate that cytokine delivery, paired with our “Tune & Track” technology will be widely adaptable to develop potent and safe affinity-tuned CAR T cells against hard-to-treat solid cancers.
