- •Subjects must not receive concurrent or prior use of an immunosuppressive agent within 14 days of the first dose of investigational agent, with the following exceptions and notes:
- •Systemic steroids at physiologic doses (equivalent to dose of oral prednisone 10 mg) are permitted. Steroids as anti-emetics for chemotherapy are not allowed.
- •Intranasal, inhaled, topical, intra-articular, and ocular corticosteroids with minimal systemic absorption are permitted.
- •Subjects with a condition with anticipated use of systemic steroids above the equivalent of 10 mg prednisone are excluded.
- •Subjects must not have a history of clinically manifested central nervous system (CNS) metastases.
- •a. Subjects with known or suspected leptomeningeal disease or cord compression are not eligible.
- •Subjects must not have had major surgery as determined by the PI within 4 weeks before the first dose of investigational agent.
- •Subjects must not have received another investigational agent within the shorter of 4 weeks or 5 half-lives before the first dose of investigational agent.
- •Subjects must not have received a live attenuated vaccine within 28 days before the first dose of investigational agent, and subjects, if enrolled, should not receive live vaccines during the study or for 180 days after the last dose of investigational agent.
- •Females who are pregnant or lactating or who intend to become pregnant during participation in the study are not eligible to participate.
- •Subjects who are of reproductive potential who refuse to use effective methods of birth control during the course of participation of the study and within 5 month for women and 7 months for men of the last dose of investigational agent are ineligible to participate in the study.

结局指标
主要结局
Phase 1b Primary Safety Outcome
时间窗: Initiation of study drug (or informed consent for SAEs) through 100 days after the last dose of study drug or initiation of a new systemic anti-cancer therapy with a maximum exposure of 34.3 months.
Number and percentage of subjects with adverse events (AEs), serious adverse events (SAEs), and dose-limiting toxicities (DLTs)
1-year Overall Survival Rate
时间窗: 1 year from initiation of study therapy
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.
