A Phase 2, Single-Arm Trial of Relacorilant in Combination With Nab-Paclitaxel and Gemcitabine in Chemotherapy-Naïve Patients With Metastatic Pancreatic Adenocarcinoma (TRIDENT)
Summary
This is a 2-part, Phase 2 study to evaluate the safety, tolerability, dosing, pharmacokinetics (PK), and efficacy of relacorilant in combination with nab-paclitaxel and gemcitabine in chemotherapy-naïve patients with metastatic pancreatic adenocarcinoma (PDAC).
Detailed description
This study will include 2 parts. In Part 1 (dose finding), approximately 6 patients will be enrolled to individual dose-finding cohorts. Cohorts will receive various dose concentrations of relacorilant, nab-paclitaxel, and gemcitabine at various dosing schedules. In all dose-finding cohorts, relacorilant will be administered orally under fed conditions, once daily for 3 days on the day before (excluding Cycle 1 Day -1), the day of, and the day after nab-paclitaxel and gemcitabine. Enrollment will be paused after each cohort has been filled until the safety review committee (SRC) provides recommendations. If maximum tolerated dose (MTD) criteria are not met in a cohort, then either a dose-finding cohort at a more intense dose and/or schedule may be enrolled, or a dose and schedule at/below the MTD may be selected as the optimal dose and schedule, and Part 2 may be initiated. If MTD criteria are met, then a dose-finding cohort at a less intense dose and/or schedule may be enrolled, or dose-finding may end without proceeding to Part 2. In Part 2 (expansion), each patient will receive the optimal dose and schedule of relacorilant, nab-paclitaxel, and gemcitabine as identified in Part 1. Analysis of Part 2 will include data for patients from Part 1 who were enrolled in the optimal dose and schedule used in Part 2.

Outcome measures
Primary
Percent of Patients who Experience Dose Limiting Toxicity (DLT) (Part 1)
The percentage of patients with a DLT is used to estimate maximum tolerated dose (MTD), the most intense dose/schedule among those evaluated at which \<33% of patients experience DLT.
Time frame: Up to 28 days after the first dose of study treatment
Number of Patients with 1 or More Adverse Events (AEs) Leading to Study Drug Discontinuations or Dose Modifications (Part 1)
Time frame: Time of first dose up to 30 days after last dose
Progression-Free Survival (PFS) (Part 2)
To evaluate PFS as the time from enrollment until first documented progressive disease (PD) by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 as determined by the Investigator, or death due to any cause, whichever comes first.
Time frame: From date of enrollment until the date of first documented progression or date of death from any cause, whichever comes first, assessed up to 12 months
Secondary
Maximum Plasma Concentration (Cmax) of Relacorilant (Part 1 and Part 2)
Time frame: Pre- and postdose on Cycle 1 Day 15 (each cycle is 28 days)
Area Under the Plasma Concentration-time Curve (AUC) of Relacorilant (Part 1 and Part 2)
Time frame: Pre- and postdose on Cycle 1 Day 15 (each cycle is 28 days)
Cmax of Nab-paclitaxel (Part 1 and Part 2)
Time frame: At serial timepoints postdose on Cycle 1 Day 15 (each cycle is 28 days)
AUC of Nab-paclitaxel (Part 1 and Part 2)
Time frame: At serial timepoints postdose on Cycle 1 Day 15 (each cycle is 28 days)
Overall Survival (OS) (Part 2)
Time frame: From date of enrollment until the date of death from any cause, whichever comes first, assessed up to 19 months
Best Overall Response (BOR) (Part 2)
Time frame: From date of enrollment until the date of first documented progression or date of death from any cause, whichever comes first, assessed up to 12 months
Objective Response Rate (ORR) (Part 2)
Time frame: From date of enrollment until the date of first documented progression or date of death from any cause, whichever comes first, assessed up to 12 months
Duration of Response (DoR) (Part 2)
Time frame: From date of first objective response until the date of first documented progression or date of death from any cause, whichever comes first, assessed up to 12 months
Clinical Benefit Rate (CBR) (Part 2)
Time frame: Week 24
Cancer Antigen 19-9 (CA19-9) Kinetics (Part 2)
Time frame: Baseline to Weeks 4, 8, and 16
Number of Patients with 1 or More Adverse Events (Part 2)
Time frame: Time of first dose up to 30 days after last dose
Number of Patients with Treatment-related Adverse Events (Part 2)
Time frame: Time of first dose up to 30 days after last dose
Number of Patients with Adverse Events by Severity (Part 2)
Time frame: Time of first dose up to 30 days after last dose
Number of Patients With 1 or More Adverse Events Leading to Study Drug Discontinuation (Part 2)
Time frame: Time of first dose up to 30 days after last dose
