Outcome Measures
Primary Outcomes (2)
Characterize the safety and feasibility of TORL-1-23 in combination with chemotherapy by analyzing the incidence of treatment emergent adverse events and serious adverse events.
Incidence of Grade greater than or equal to 3 (using CTCAE V5.0) treatment-emergent adverse event (TEAE) and related serious adverse event (SAE)
Treatment during Cycle 1 to Cycle 4 (Each cycle is 21 days)
To assess the efficacy of neoadjuvant TORL-1-23 in combination with chemotherapy
Determination of percentage CRS3 score for each treatment arm
postoperative after Cycle 4 (Each cycle is 21 days)
Secondary Outcomes (2)
To assess the tolerability of TORL-1-23 in combination with chemotherapy
Treatment up to Cycle 8 (each cycle is 21 days)
To characterize duration of benefit for TORL-1-23 plus chemotherapy
Measured up to 15 months after surgery
Study Arms (3)
Treatment Arm A: TORL-1-23 and paclitaxel
EXPERIMENTALAdministered once every three weeks
Treatment Arm B: TORL-1-23 and carboplatin
EXPERIMENTALAdministered once every three weeks
Treatment Arm C: TORL-1-23, paclitaxel, and carboplatin
EXPERIMENTALAdministered once every three weeks
