Titre : ODM-201 Maintenance Therapy in Patients With Metastatic Castration Resistant Prostate Cancer (mCRPC) Previously Treated With Novel Hormonal Agents and Non-progressive Disease After Subsequent Treatment With a Taxane: A Multicenter Randomized Double-blind Placebo-controlled Phase II Trial.

Spécialité : Organes génitaux masculins
Localisation : C61 - Tumeur maligne de la prostate
Informations complémentaires
Schéma : The treatment of metastatic castration-resistant prostate cancer has evolved rapidly over the past few years. First line treatment with one of the novel antihormonal drugs abiraterone or enzalutamide followed by chemotherapy with docetaxel is now standard of care. If a patient has disease stabilization on chemotherapy he undergoes a watchful waiting period and further treatment is only started at the time of disease progression. This trial tests the immediate use of the novel androgen receptor antagonist ODM-201 as maintenance treatment after chemotherapy aiming at prolonging radiographic progression free survival as compared to watchful waiting.

The main objective of the trial is to assess impact of maintenance therapy with ODM-201 on radiographic progression-free survival (rPFS) of patients with mCRPC pretreated with novel hormonal agents who have non-progressive disease after chemotherapy with a taxane.

Phase : II

Stade : Métastasique

Critères d'inclusion et de non-inclusion
Critères d'inclusion : - Written informed consent according to Swiss law and ICH/GCP regulations before registration and prior to any trial specific procedures not part of normal medical care.
- Histologically or cytologically confirmed diagnosis of adenocarcinoma of the prostate
- Castration resistance: tumor progression after orchiectomy or during treatment with GnRH analogues (agonists or antagonists)
- Metastatic disease, documented by imaging
- Total testosterone ≤ 50 ng/dL (≤ 1.7 nmol/L)
- Treatment with abiraterone AND/OR enzalutamide for at least 8 weeks prior to taxane based chemotherapy
- No evidence of disease progression after chemotherapy with docetaxel (at least cumulative dose of ≥ 300 mg/m2 or total dose ≥ 600mg) or cabazitaxel (at least cumulative dose of ≥ 80 mg/m2 or total dose ≥ 160 mg)
* No evidence of progression on imaging according to PCWG3
* No evidence of progression on PSA levels referred to the nadir since start of taxane treatment (PSA progression defined as > 25% increase of PSA level or >50% if PSA decrease under chemotherapy >50% AND > 5 ng/mL increase in the absolute PSA value)
- Non-surgically castrated patient agrees on ongoing use of GnRH analogues (agonists or antagonists) during the trial
- Planned start of trial treatment 2 to 8 weeks after last taxane dose
- Male patient 18 years or older
- WHO performance status of ≤2
- Laboratory values as specified below
* alanine aminotransferase (ALT) ≤ 2.5 x ULN (except for patients with liver metastases ≤ 5.0 x ULN)
* Total bilirubin ≤ 1.5 x ULN (except for patients with Gilbert's disease ≤ 3.0 x ULN)
* Estimated creatinine clearance using the Cockcroft-Gault formula > 30 mL/minute
* Blood counts at screening: haemoglobin ≥ 90 g/L, absolute neutrophil count ≥ 1500/μl (1.5x109/L), platelet count ≥ 100,000/μl (100x109/L) (patient must not have received any growth factor or blood transfusion within 7 days of the haematology laboratory obtained at screening)
- Adequate cardiac function: Left ventricular Ejection Fraction (LVEF) ≥ 40% as determined by echocardiography (ECHO)
- Patient is able and willing to swallow trial drug as whole tablet
- Sexually active male subjects must agree to use condoms as an effective barrier method and refrain from sperm donation, and/or their female partners of reproductive potential to use a method of effective birth control, during the study treatment and for 3 months after the end of the treatment.
- Patient agrees to participate in the mandatory translational research project

Critères de non-inclusion : - Prior chemotherapy for prostate cancer except from chemotherapy with a taxane
- Concurrent disease requiring higher doses of corticosteroid than the equivalent of 10 mg prednisone per day
- Known CNS or leptomeningeal metastases
- Clinical or radiological evidence of current spinal cord compression
- History of hematologic or primary solid tumor malignancy, unless in remission for at least 2 years from registration with the exception of localized non-melanoma skin cancer or carcinoma in situ having undergone complete resection.
- Prior therapy for mCRPC with modern anti-hormonal treatment except for enzalutamide or abiraterone
- Concurrent treatment with other experimental drugs or treatment in a clinical trial within 30 days prior to trial entry (except clinical trial SAKK 96/12)
- Concomitant use of other anti-cancer drugs or radiotherapy except for local pain control and GnRH analogues
- Severe or uncontrolled cardiovascular disease
- Acute exacerbations of chronic illnesses, serious infections, or major surgery within 4 weeks before expected start of treatment
- ECG abnormalities of Q-wave infarction, unless identified ≥ 6 months prior to registration or QTc interval >480 msec
- Known gastrointestinal (GI) disease or GI procedure that could interfere with the GI absorption or tolerance of ODM-201
- Known hypersensitivity to trial drug or to any component of the trial drug
- Any other serious underlying medical, psychiatric, psychological, familial or geographical condition, which in the judgment of the investigator may interfere with the planned staging, treatment and follow-up, affect patient compliance or place the patient at high risk from treatment-related complications.
