The main purposes of this study are to learn how effective the study drug combinations are in treating patients with metastatic pancreatic adenocarcinoma. The drug combinations are APX005M+Nivolumab+Gemcitabine+nab-Paclitaxel, or APX005M+Gemcitabine+nab-Paclitaxel.

Safety and Efficacy of APX005M With Gemcitabine and Nab-Paclitaxel With or Without Nivolumab in Patients With Previously Untreated Metastatic Pancreatic Adenocarcinoma

Open-label, Multicenter, Phase 1b/2 Clinical Study to Evaluate the Safety and Efficacy of CD40 Agonistic Monoclonal Antibody (APX005M) Administered Together With Gemcitabine and Nab-Paclitaxel With or Without PD-1 Blocking Antibody (Nivolumab) in Patients With Previously Untreated Metastatic Pancreatic Adenocarcinoma

Number and percentage of subjects with adverse events (AEs), serious adverse events (SAEs), and dose-limiting toxicities (DLTs)

The primary endpoint was the 1-year OS rate of each treatment arm, compared to the historical rate of 35% for gemcitabine and nab-Paclitaxel. OS was defined as the time from treatment initiation until death from any cause. Patients who were not reported as having died at the time of analysis were censored at the most recent contact date. OS and the 1-year OS rate were estimated by the Kaplan-Meier method for each treatment arm. The 1-year OS rate and corresponding one-sided, 95% CI were calculated to determine whether the lower bound of the CI excluded the assumed historical value of 35%. P values were calculated using a one-sided, one-sample z-test of the Kaplan-Meier estimate of the 1-year OS rate (and its standard error) against the historical rate of 35%. This study was not powered for statistical comparison between arms.

Phase 1b DLT-Evaluable Population. Overall Response Rate is defined as the proportion of participants who had a best overall response of Complete Response (CR) or Partial Response (PR) as defined by RECIST v1.1. Overall Response (OR) = CR + PR.

DOR was the time from the first tumor assessment demonstrating response until the date of radiographic disease progression. DOR and the CIs were estimated using the Kaplan-Meier method.

Phase 2 Secondary Efficacy Outcome. Disease Control Rate is defined as the proportion of participants who had a best overall response of Complete Response (CR), Partial Response (PR), or Stable Disease (SD) as defined by RECIST v1.1.

PFS is defined as the time from treatment initiation until radiographic disease progression or death (whichever occurred first). PFS and the CIs were estimated using the Kaplan-Meier method.

Phase 2 Secondary Efficacy Outcome. Overall Response Rate is defined as the proportion of participants who had a best overall response of Complete Response (CR) or Partial Response (PR) as defined by RECIST v1.1. Overall Response (OR) = CR + PR.

Safety analysis was conducted on all Phase 1b and Phase 2 patients who received at least one dose of any study drug. For safety analyses, patients were grouped according to the study treatment actually received ('as treated'). Specifically, two phase 2 patients were randomly allocated to Gem/NP/Nivolumab/APX005M but only received doses of Gem, NP, and Nivolumab (that is, APX005M was not received); these two patients were grouped as Gem/NP/APX005M for safety analyses.

The Eastern Cooperative Oncology Group (ECOG) Scale of Performance Status is one such measurement. It describes a patient's level of functioning in terms of their ability to care for themself, daily activity, and physical ability (walking, working, etc.). The ECOG Performance Status ranges from 0 (fully active, able to carry on all pre-disease performance without restriction) to 5 (dead).
