About this study

Official title: A Phase 2, Randomized, Open-Label, 3-arm Study of Relacorilant in Combination With Nab-Paclitaxel for Patients With Recurrent Platinum-Resistant Ovarian, Fallopian Tube, or Primary Peritoneal Cancer

This is a Phase 2, open-label, randomized, 3-arm study to evaluate progression-free survival (PFS) in patients with recurrent platinum-resistant ovarian, fallopian tube, or primary peritoneal cancer treated with intermittent or continuous regimens of relacorilant in combination with nab-paclitaxel compared with patients treated with nab-paclitaxel alone.

Read the detailed description

Relacorilant is a small molecule antagonist of the glucocorticoid receptor (GR). The goals of this study are to evaluate the efficacy of relacorilant either administered daily (continuous) or on the day prior, the day of, and the day after chemotherapy (intermittent) in combination with nab-paclitaxel in the treatment of platinum-resistant ovarian, fallopian tube, or primary peritoneal cancers compared with nab-paclitaxel alone. The safety, pharmacokinetics (PK), and pharmacodynamic profile of relacorilant in combination with nab-paclitaxel will also be assessed.

Eligible patients will be randomized 1:1:1 to one of the following three treatment arms. Patient randomization will be stratified by treatment-free interval from most recent taxane (relapsed within 6 months vs >6 months) and presence of ascites (yes vs no).

  • Arm A (Continuous relacorilant): Relacorilant starting at 100 mg, administered orally, once daily every day in combination with nab-paclitaxel on Days 1, 8, and 15 of each 28-day cycle.
  • Arm B (Intermittent relacorilant): Relacorilant 150 mg, administered orally, on the day before (excluding Cycle 1, Day -1), the day of, and the day after nab-paclitaxel, in combination with nab-paclitaxel on Days 1, 8, and 15 of each 28-day cycle.
  • Arm C (Comparator): Nab-paclitaxel on Days 1, 8, and 15 of each 28-day cycle.

Patients will remain on study treatment until reaching a protocol-defined event of disease progression (PD), experiencing unmanageable toxicity, or until other treatment discontinuation criteria are met. All patients will be followed for progression, subsequent therapies, and survival in the long-term follow-up phase. Patients in Arm C who experience unequivocal PD per RECIST v1.1 will be given the opportunity to receive relacorilant in combination with nab-paclitaxel after discussion with the Medical Monitor (Crossover patients).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Progression-free Survival (PFS)

    To assess time from randomization until the date of first documented progressive disease (PD) by RECIST v1.1 (as determined by the Investigator at the local site), or death due to any cause, whichever occurs first.

    Measured: Baseline and up to 15 months

Secondary outcomes (11)

  1. Objective Response Rate (ORR)

    To assess the proportion of patients with measurable disease at Baseline who attain complete response (CR) or partial response (PR) by RECIST v1.1 (confirmation not required).

    Measured: Baseline and up to 15 months

  2. Duration of Response (DOR)

    To assess the time from when response (CR or PR) was first documented to the first objectively documented PD or death (whichever occurs first)

    Measured: From first documented response up to 12 months

  3. Cancer Antigen 125 (CA-125) Response According to Gynecological Cancer Intergroup Criteria (GCIG)

    To assess the overall CA-125 response per GCIG criteria. Response was defined as ≥50% reduction in CA-125 from a pre-treatment sample. Patients whose CA-125 levels fall within the reference range are classified as complete responders.

    Measured: Baseline and up to 15 months

  4. Best Overall Response (BOR)

    To assess the best response (CR, PR, stable disease [SD], or PD) recorded from the date of randomization until PD/recurrence (or death)

    Measured: Baseline and up to 15 months

  5. PFS Rate at 6 and 12 Months

    To assess the proportion of patients who have not progressed according to RECIST v1.1 criteria at 6 and 12 months. Values are Kaplan-Meier estimates of the patients progression-free at the time points specified.

    Measured: 6 and 12 months

  6. PFS in Patients Who Cross Over to Continuous Treatment at Time of Initial PD

    To assess the time from crossover Baseline (initial PD) until the earliest date of subsequent PD by RECIST v1.1, as determined by the Investigator at the local site, or death from any cause, whichever comes first.

    Measured: Crossover Baseline (Day 50) up to Day 272

  7. ORR in Patients Who Cross Over to Continuous Treatment at Time of Initial PD

    To assess the proportion of patients with measurable disease at the crossover Baseline who attain confirmed CR or PR by RECIST v1.1

    Measured: Crossover Baseline (Day 50) up to Day 272

  8. DOR in Patients Who Cross Over to Continuous Treatment at Time of Initial PD

    To assess the time from when the first objective response (CR or PR) in the crossover period to the first objectively documented subsequent PD, or death (whichever occurs first)

    Measured: From the time of objective response in the crossover period to the time of subsequent PD

  9. BOR in Patients Who Cross Over to Continuous Treatment at Time of Initial PD

    To assess the best overall response (CR, PR, SD, or PD) recorded in the crossover period

    Measured: Crossover Baseline (Day 50) up to Day 272

  10. Overall Survival (OS)

    To assess the time from randomization to death by any cause.

    Measured: Up to 31 months

  11. Overall Response According to Combined RECIST v1.1 + GCIG Criteria

    To assess the proportion of patients with measurable disease at Baseline who attain confirmed CR or PR by RECIST v1.1 and GCIG criteria. GCIG response was defined as ≥50% reduction in CA-125 from a pre-treatment sample.

    Measured: Baseline and up to 15 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Relacorilant and Nab-paclitaxel in people with Recurrent Ovarian Cancer and Recurrent Fallopian Tube Carcinoma, run by Corcept Therapeutics at 24 sites in 5 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 28 inclusion and 26 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Oct 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 24 sites in United States, Spain, Belgium, Italy, Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 30 Apr 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression-free Survival (PFS) (time frame: Baseline and up to 15 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03776812, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Oct 2025; AzTrials last refreshed its copy on 7 Nov 2026.
