Brief summary
This is an open-label Phase 1b dose-escalation study to assess the safety, tolerability, and PK of OMP-54F28 when combined with nab-paclitaxel and gemcitabine. OMP-54F28 will be administered IV on Days 1 and 15 of each 28-day cycle. Nab-paclitaxel (125 mg/m2) and gemcitabine (1000 mg/m2) will be administered IV on Days 1, 8, and 15 of each cycle. The planned dose levels of OMP-54F28 are 3.5 mg/kg and 7.0 mg/kg.
Detailed description
Depending on safety in this study, additional lower or intermediate dose levels may be evaluated. Depending on emerging safety data from the Phase 1a study 54F28-001 with continuing dose escalation, additional higher dose levels of OMP-54F28 may be evaluated in this study. No dose escalation of OMP-54F28 will be allowed within a dose cohort. Once the maximum tolerated dose (MTD) or maximum administered dose (MAD) has been determined, up to 10 patients may be enrolled in the cohort-expansion phase to better characterize the safety, tolerability and PK of OMP-54F28 combined with nab-paclitaxel and gemcitabine. Up to approximately 34 patients may be enrolled into the study.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Safety and tolerability of OMP-54F28 in combination with nab-paclitaxel and gemcitabine in patients with previously untreated Stage IV pancreatic cancer | Subjects will be treated and observed for DLT through the end of the first cycle (from Day 0 - 28) | The maximum tolerated dose (MTD) will be determined in patients treated with gemcitabine in combination with weekly nab-paclitaxel (from Day 0 - 28) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Pharmacokinetics (PK) of OMP-54F28 when administered in combination with nabpaclitaxel and gemcitabine to patients with previously untreated Stage IV pancreatic cancer | Plasma sample for Pharmacokinetics (PK) analysis to be obtained prior to the gemcitabine infusion and before nabpaclitaxel infusion from Day 0 to treatment termination | Apparent half life, AUC, clearance, volume of distribution |
