The first in human clinical study is planned as an open-label, multicentre, two-part, Phase 1/2a study to assess the safety, pharmacokinetics, and efficacy of PBP1510 in patients with advanced/metastatic pancreatic cancer. Part 1 (Phase 1) is a dose-escalation phase, wherein 2 cycles of PBP1510 will be administered, as monotherapy (monotherapy cohorts) or in combination with gemcitabine (combination cohorts) in advanced/metastatic pancreatic cancer patients whose tumours have progressed on at least one previous line of chemotherapy for locally advanced/metastatic disease. The RP2D will be selected based on the analysis of the PK, safety, and efficacy data. Part 2 (Phase 2a) will be an open-label study and patients will be administered the RP2D of PBP1510 derived from Part 1, for 4 cycles in combination with gemcitabine for advanced/metastatic pancreatic cancer patients whose tumour has progressed on one previous line of chemotherapy for locally advanced/metastatic disease.
The first in human clinical study is planned as an open-label, dose-escalation, and dose-expansion, multicentre, two-part, Phase 1/2a study of PBP1510 administered to patients with advanced/metastatic pancreatic cancer. The study will be conducted in two parts, Part 1 as a PBP1510 single agent dose-escalation, and PBP1510 dose-escalation in combination with gemcitabine, and Part 2 as PBP1510 dose-expansion at the RP2D in combination with gemcitabine.
