Fase 1/2a dosis-eskalerings- og udvidelsesundersøgelse til evaluering af sikkerheden, tolerabiliteten og farmakokinetikken af CORT125281 med enzalutamid hos patienter med metastatisk kastrationsresistent prostatacancer

Detaljeret beskrivelse
CORT125281 er en selektiv glukokortikoid receptor (GR) antagonist. I denne undersøgelse vil CORT125281 blive administreret oralt i kombination med enzalutamid til patienter med metastatisk kastrationsresistent prostatacancer (mCRPC) for at evaluere regimets sikkerhed, tolerabilitet, farmakokinetik, farmakodynamik og foreløbig effektivitet. Undersøgelsen består af to faser: en dosisbestemmelsesfase og en udvidelsesfase. Dosisbestemmelsesfasen er designet til at bestemme dosisbegrænsende toksiciteter og RD af CORT125281 plus enzalutamid hos patienter med mCRPC. Når det anbefalede doseringsregime er blevet bestemt, vil følgende ekspansionskohorter blive optaget og behandlet med CORT125281 plus enzalutamid på det anbefalede dosisniveau.
Abi-resistent kohorte: Patienter, der har udviklet sig under behandling med abirateron, og som ikke har modtaget anden androgenreceptor (AR)-blokerende behandling
ARant-resistent kohorte: Patienter, der har udviklet sig under behandling med enzalutamid eller andre andengenerations AR-hæmmere.
Effekten af mad på CORT125281 PK vil blive vurderet hos en del af de patienter, der er indskrevet i ekspansionsfasen. De to ekspansionskohorter vil blive tilmeldt parallelt.
I hver fase af undersøgelsen vil der blive udført rutinevurderinger af sikkerhed og tolerabilitet, og prøver vil blive indsamlet for at bestemme standard PK-parametre for CORT125281, enzalutamid og deres vigtigste metabolitter. PD, livskvalitetsevalueringer og foreløbige evalueringer af antitumoraktivitet af CORT125281 med enzalutamid vil blive udført gennem hele studiet.

Assess the maximum tolerated dose (MTD) and/or biologically active doses of exicorilant in combination with enzalutamide to identify the recommended dose (RD) for Phase 2 studies based on the number of patients who experienced a DLT while receiving exicorilant in combination with enzalutamide.
DLTs were defined as any of the protocol-specified toxicities that the Investigator considered possibly or probably related to study drug that occurred during the DLT-evaluation period.
The MTD is defined as the highest dose at which the DLT rate was <33%.

Tidsramme: 4, 6, and 12 months
|
Assess the percentage of patients who are progression-free by PSA criteria, or death.
PSA progression was defined as the first occurrence of 50% or greater increase in PSA levels.
Values are Kaplan-Meier estimates of the patients progression free at the time points specified.
|
4, 6, and 12 months
|
|
Time to First Symptomatic Skeletal Event (SSE)
Tidsramme: Up to 39 months
|
Assess the time to first SSE defined as symptomatic fracture, radiation or surgery to bone, or spinal cord compression.
Kaplan-Meier estimates of time to first SSE were calculated as (earliest date of SSE or censoring - date of first study treatment + 1)/30.4375.
|
Up to 39 months
|
|
Time to Progression by Radiographic Criteria
Tidsramme: Up to 22 months
|
Assess radiographic progression free survival (PFS) defined as the time interval from first dose of study drug (exicorilant and/or enzalutamide) to the date when the first site of disease progression is found on computerized tomography (CT), magnetic resonance imaging (MRI), or radionucleotide bone scan per PCWG3/mRECIST v1.1, or death whichever occurs first.
The data values are Kaplan-Meier estimates.

Up to 22 months

Percentage of Patients Who Are Progression-Free by Radiographic Criteria at 4, 6, and 12 Months
Tidsramme: 4, 6, and 12 months
|
Assess the percentage of patients who are progression-free by radiographic criteria per PCWG3/RECIST v1.1, or death whichever occurs first.
Values are Kaplan-Meier estimates of the patients progression free at the time points specified.
|
4, 6, and 12 months
|
|
Time to Progression by Clinical or Radiographic Criteria
Tidsramme: Up to 22 months
|
Determine PFS by clinical or radiographic criteria, or death, whichever occurs first.
Clinical progression was defined as treatment discontinuation due to disease progression by investigator assessment per PCWG3/mRECIST v1.1, or by PSA criteria.
The data values are Kaplan-Meier estimates.

Percentage of Patients Who Are Progression-Free by Clinical or Radiographic Criteria at 4, 6, and 12 Months
Tidsramme: 4, 6, and 12 months
|
Assess the percentage of patients who are progression-free by clinical or radiographic measures at 4, 6, and 12 months.
Values are Kaplan-Meier estimates of the patients progression free at the time points specified.
|
4, 6, and 12 months
|
|
Time to Progression by Clinical or Biochemical Criteria
Tidsramme: Up to 33 months
|
Determine PFS by clinical criteria or biochemical criteria (defined as treatment discontinuation due to clinical progression by investigator assessment, or by PSA criteria) PCWG3/mRECIST v1.1, or death whichever occurs first.
The data values are Kaplan-Meier estimates.
|
Up to 33 months

Percentage of Patients Who Are Progression-Free by Clinical or Biochemical Criteria at 4, 6, and 12 Months
Tidsramme: 4, 6, and 12 months
|
Assess the percentage of patients who are progression-free by clinical or biochemical criteria (defined as treatment discontinuation due to clinical progression by investigator assessment or by PSA criteria) PCWG3/mRECIST v1.1, or death whichever occurs first at 4, 6, and 12 months.
Values are Kaplan-Meier estimates of the patients progression free at the time points specified.
|
4, 6, and 12 months
|
|
Duration of Response (DOR)
Tidsramme: Up to 11 months
|
Determine the DOR as defined as the time from the first occurrence of a documented objective tumor response to the time of radiographic progression (per investigator using PCWG3/mRECIST v1.1 criteria) or death from any cause on study, whichever occurs first.
DOR was calculated as (earliest date of progression, death, or censoring - date of first documented objective response +1)/30.4375.
The data values are Kaplan-Meier estimates.
|
Up to 11 months
|
|
Overall Survival (OS)
Tidsramme: Up to 52 months
|
Determine OS assessed as the time from the first dose of study drug (exicorilant and/or enzalutamide) to the date of death from any cause.
The data values are Kaplan-Meier estimates.
|
Up to 52 months
