Study of Relacorilant in Combination With Nab-Paclitaxel in Patients With Metastatic Pancreatic Ductal Adenocarcinoma (RELIANT)

A Phase 3 Study of Relacorilant in Combination With Nab-Paclitaxel in Patients With Metastatic Pancreatic Ductal Adenocarcinoma (RELIANT)

This is a Phase 3, open-label study to evaluate the objective response rate (ORR), in patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) treated with relacorilant in combination with nab-paclitaxel, according to blinded independent central review.

Study Overview

• Status: Terminated
• Conditions: Metastatic Pancreatic Ductal Adenocarcinoma
• Intervention / Treatment: Drug: Relacorilant, 100 mg and 25 mg; Drug: Nab-paclitaxel

Detailed Description

Relacorilant is a small-molecule antagonist of the glucocorticoid receptor (GR). The goals of this study are to evaluate the efficacy, safety, and pharmacokinetics (PK) of relacorilant in combination with nab-paclitaxel in the treatment of metastatic pancreatic ductal adenocarcinoma.

Eligible patients are those with mPDAC who have received at least 2 prior lines of therapy for pancreatic ductal adenocarcinoma in any setting, including at least 1 prior gemcitabine-based therapy and at least 1 prior fluoropyrimidine-based therapy.

Patients will receive treatment until progressive disease (PD) (per RECIST v1.1) as determined by the Investigator, experiencing unmanageable toxicity, or until other treatment discontinuation criteria are met. All patients will be followed for documentation of disease progression and survival information (i.e., date and cause of death) and subsequent treatment.

Concurrent treatment with mifepristone or other GR antagonists

Any clinically significant uncontrolled condition(s) or any medical condition which in the opinion of the Investigator places the patient at an unacceptably high risk for toxicities or impair study participation or cooperation

Any major surgery within 21 days prior to enrollment

Endoscopic retrograde cholangiopancreatography with persistence of any of the following:

A history of human immunodeficiency virus (HIV) or current chronic/active infection with hepatitis C virus (HCV) or hepatitis B virus (HBV). (Patients with chronic or active hepatitis B as diagnosed by serologic tests are excluded from the study. In equivocal cases, hepatitis B or C polymerase chain reaction results may be performed and must be negative for enrollment.)

A rapid decline in KPS score or serum albumin (≥20%), or have progressive pain symptoms indicative of rapid clinical deterioration, in the opinion of the Investigator, prior to enrollment. These patients will become ineligible if rapid decline is observed during the screening period.

Tumor assessment consisted of computerized tomography (CT) scan or, with Sponsor approval, magnetic resonance imaging (MRI). CR was defined as disappearance of all target lesions; any pathological lymph nodes (whether target or nontarget) must have reduction in short axis to <10 mm. PR was defined as ≥30% decrease in the sum of the diameters (SOD) of target lesions.	Baseline and up to 32 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Objective Response Rate (ORR) Per Investigator Assessment	Percentage of patients with measurable disease at baseline who achieved confirmed CR or PR per RECIST v1.1, as assessed by the Investigator. Tumor assessment consisted of CT scan or, with Sponsor approval, MRI. CR was defined as disappearance of all target lesions; any pathological lymph nodes (whether target or nontarget) must have reduction in short axis to <10 mm.
