Dose EscalationEXPERIMENTALDose escalation is a 3+3 design, including a Dose Limiting Toxicity (DLT) evaluation period. The dose expansion dose level will be determined in this part with escalating doses of AB680 in combination with zimberelimab at the recommended phase 2 dose (RP2D) and the standard nab-paclitaxel and gemcitabine chemotherapy regimen in participants with advanced pancreatic cancer.
Dose Expansion (AB680+zimberelimab+ NP/Gem): Cohort A (front-line/1L)EXPERIMENTALParticipants with advanced pancreatic cancer, naïve to any prior treatment will receive AB680 (at the RP2D identified during dose escalation) combined with zimberelimab and the standard nab-paclitaxel (NP) and gemcitabine (Gem) (NP/Gem) chemotherapy regimen
Dose Expansion (AB680+zimberelimab+NP/Gem):Cohort A1 (front-line/1L)EXPERIMENTALParticipants with advanced pancreatic cancer, naïve to any prior treatment will receive AB680 (at the RP2D identified during dose escalation) combined with zimberelimab and the standard nab-paclitaxel (NP) and gemcitabine (Gem) (NP/Gem) chemotherapy regimen
Dose Expansion (AB680 + NP/Gem): Cohort A2 (front-line/1L)EXPERIMENTALParticipants with advanced pancreatic cancer who are naïve to any prior treatment will receive AB680 (at the RP2D identified during dose escalation) and the standard NP/Gem chemotherapy regimen.
Dose Expansion (AB680 + zimberelimab + NP/Gem): Cohort B (second-line/2L)EXPERIMENTALParticipants with advance pancreatic cancer who have received 1 prior line of treatment will receive AB680 (at the RP2D identified during dose escalation) combined with zimberelimab and NP-Gem chemotherapy regimen.
Dose Expansion (AB680 + zimberelimab + NP/Gem): Cohort C (front-line/1L)EXPERIMENTALParticipants with advanced pancreatic cancer naïve to any prior treatment will receive AB680 combined with zimberelimab and NP-Gem chemotherapy regimen.
Dose Expansion (AB680 + NP/Gem): Cohort D (front-line/1L)EXPERIMENTALParticipants with advanced pancreatic cancer naïve to any prior treatment will receive AB680 combined with NP-Gem chemotherapy regimen.
