ArmTypeDescription
AO-176 Dose EscalationEXPERIMENTALEach dose escalation cohort will initially recruit 3 patients to receive AO-176 in a standard 3+3 design; cohorts will be expanded in the event of a DLT.
AO-176 Dose ExpansionEXPERIMENTALOnce the MTD/RP2D has been established, tumor-specific dose expansion cohorts will be recruited to further assess safety and evaluate preliminary efficacy of AO-176.
AO-176 + Paclitaxel Dose EscalationEXPERIMENTALEach dose escalation cohort will initially recruit 3 patients to receive AO-176 and paclitaxel in a standard 3+3 design; cohorts will be expanded in the event of a DLT.
AO-176 + Paclitaxel Dose ExpansionEXPERIMENTALOnce the MTD/RP2D has been established, tumor-specific dose expansion cohorts will be recruited to further assess safety and evaluate preliminary efficacy of AO-176 + paclitaxel.
AO-176 + Pembrolizumab Dose EscalationEXPERIMENTALEach dose escalation cohort will initially recruit 3 patients to receive AO-176 and pembrolizumab in a standard 3+3 design; cohorts will be expanded in the event of a DLT.
AO-176 + Pembrolizumab Dose ExpansionEXPERIMENTALOnce the MTD/RP2D has been established, tumor-specific dose expansion cohorts will be recruited to further assess safety and evaluate preliminary efficacy of AO-176 + pembrolizumab.
