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

Trial ID # NCT03776812
Phase II
Drug Class Hormonal Therapy: GR
Drug Name Relacorilant
Alternate Drug Names RELA, CORT125134
Drugs in Trial nab-Paclitaxel, Relacorilant
Eligible Participant

Platinum resistant and refractory ovarian cancer

Patients Enrolled


Therapy Setting


Study Design

Open-Label, Randomized


ORR, DoR, PFS, OS, evaluated per RECIST


Intermittent Rel+Nab (n=60) vs Nab (n=60):

ORR: 35.7 vs 35.8%
PFS: 5.6 vs 3.8 months, HR: 0.66 (0.44-0.98, p=0.038)
DoR: 5.6 vs 3.7 months, HR: 0.36 (0.16-0.77, p=0.006)
OS: 13.9 vs 12.2 months, HR: 0.67 (0.43-1.03, p=0.066)

Exploratory analysis: no primary Pt-Rf and 1-3 prior therapies (Phase III inclusion criteria); GR high:
Intermittent Rel+Nab vs Nab:
ORR: 41.9 vs 38.6%
PFS: 5.6 vs 3.8 months, HR: 0.58 (0.37-0.91, p=0.016)
DoR: 5.6 vs 3.6 months, HR: 0.26 (0.11-0.52, p=0.001)
OS: 13.9 vs 12. 2 months, HR: 0.52 (0.31-0.86, p=0.010)

High tumor GR: GR IHC H-score ≥100 (65%, 82/129):
High GR is associated with non-response to Nab-only (SD or PD)
High GR is associated with good response (PR or CR) in patients receiving Rel + Nab
2 P= 0.037)

Clinically Significant Adverse Events

Intermittent Rel+Nab vs Nab:
Serious AE:
Grade 3-4 AE: neutropenia (6.7 vs 13.3%)


Intermittent relacorilant+nab-paclitaxel improves PFS and DoR and has a favorable safety profile in recurrent platinum resistant and/or platinum refractory ovarian cancer patients
