E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To ascertain whether the survival time distribution for patients randomized to the investigational arm is consistent with longer survival as compared to patients randomized to the control arm. |
|
E.2.2 | Secondary objectives of the trial |
To compare the arms with respect to the proportion of patients having a milestone Day 140 status of alive without event (within the window of Day 125-155 post randomization). An event is having disease progression or death on or before Day 140. NOTE: Day 140, as measured from the date of randomization, will occur normally after Cycle 6 (prior to Cycle 7) study treatment. However, the milestone Day 140 disease assessment must be completed within the inclusive window of Day 125 to Day 155 post-randomization, regardless of the timing of Cycle 6 treatment (e.g., if treatment scheduling at any time has been delayed). |

E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
FARMACOCINETICA/FARMACODINAMICA: Versione:1.1 Data:2010/05/10 Titolo:Studio, supplementare al protocollo OGX-011-11, di farmacocinetica e monitoraggio cardiaco: “Studio di fase III, randomizzato di confronto tra il trattamento standard di prima linea Docetaxel/Prednisone e il trattamento con Docetaxel/Prednisone associato a Custirsen (OGX-011) in uomini con carcinoma prostatico metastatico resistente alla castrazione”. Obiettivi:1. Determinare se Custirsen da solo, o somministrato in associazione con Docetaxel altera gli intervalli e la morfologia dell`elettrocardiogramma, con particolare attenzione ai cambiamenti nella durata dell’intervallo di QTcF 2. Valutare se la co-somministrazione di Docetaxel e Custirsen altera la farmacocinetica di Custirsen. 3. Valutare se la co-sominnistrazione di Docetaxel e Custirsen altera la farmacocinetica di Docetaxel. 4. Valutare i metaboliti urinari di Custirsen
ALTRI SOTTOSTUDI: Il supplemento al protocollo OGX-011-11 prevede anche il monitoraggio cardiaco.

E.3 | Principal inclusion criteria |
Subjects must meet ALL of the following criteria to be eligible for inclusion into the study: 1. Age ≥ 18 years on the date of consent. 2. Histological or cytological diagnosis of adenocarcinoma of the prostate. 3. Metastatic disease on chest, abdominal, or pelvic CT and/or bone scan. 4. Systemic chemotherapy indicated due to progression while on or after androgen ablative therapy defined as: a. Progressive measurable disease: at least a 20% increase in the sum of the longest diameters of measurable lesions over the smallest sum observed –or the appearance of one or more new lesions as assessed by CT scan during hormone ablation treatment. Measurable lesions are nodal or visceral soft-tissue lesions with nodal lesions ≥ 20 mm in diameter or visceral/soft-tissue lesions ≥ 10 mm in diameter (see Section 6.3.1.1). OR b. Bone Scan Progression: appearance of 2 or more new lesions on bone scan during hormone ablation treatment. OR c. Increasing serum PSA level: Two consecutive increases in PSA levels documented over a previous reference value obtained at least one week apart are required. If the third PSA value is less than the second, an additional fourth test to confirm a rising PSA is acceptable. A minimum starting value of 5.0 ng/mL is required for study randomization. NOTE: Androgen ablative therapy may have included either medical or surgical castration. 5. Baseline laboratory values as stated below: a. Creatinine ≤ 1.5 x upper limit of normal (ULN). b. Bilirubin ≤ 1.1 x ULN (unless elevated secondary to conditions such as Gilbert’s disease). c. SGOT (AST) ≤ 1.5 x ULN. d. Castrate serum testosterone level (< 50 ng/dL-or- < 1.7 nmol/L). 6. Must be willing to continue primary androgen suppression with gonadotropin-releasing hormone (GnRH) analogues throughout the study, unless treated with bilateral orchiectomy. 7. Adequate bone marrow function defined at screening as ANC ≥ 1.5 x 109 cells /L and platelet count ≥ 100 x 109 /L. 8. Karnofsky score ≥ 70% (see Appendix 17.2). 9. At least 28 days has passed since completing radiotherapy (exception for radiotherapy: at least 7 days since completing a single fraction of ≤ 800 cGy to a restricted field or limited-field radiotherapy to non-marrow bearing area such as an extremity or orbit) at the time of randomization. 10. At least 4 weeks have passed since receiving any investigational agent at the time of randomization. 11. Has recovered from any other therapy related toxicity to ≤ grade 2, (except alopecia, anemia and any signs or symptoms of androgen deprivation therapy). 12. Patient must be willing to not add, delete or change their current bisphosphonate usage throughout study treatment to assure that adverse event reporting is not confounded by changing their bisphosphonate usage (unless the deletion or change is for toxicity associated with bisphosphonate usage). 13. Patients receiving more than 10 mg of prednisone per day (or steroid equivalent) at screening must be willing to have the dose reduced to 10 mg of prednisone per day for at least 7 days prior to randomization and maintained throughout study treatment. 14. Written informed consent must be obtained prior to any protocol-specific procedures being performed. |

E.4 | Principal exclusion criteria |
Subjects meeting ANY of the following exclusion criteria will NOT be eligible for inclusion into the study: 1. Received any other cytotoxic chemotherapy as treatment. 2. Received any cycling or intermittent hormonal treatment 28 days prior to randomization. 3. Participated in a prior clinical study evaluating custirsen. 4. History of or current documented brain metastasis or carcinomatous meningitis, treated or untreated. (Brain imaging for asymptomatic patients is not required.) 5. Current symptomatic cord compression requiring surgery or radiation therapy. (Once successfully treated and there has been no progression, patients are eligible for the study.) 6. Active second malignancy (except non melanomatous skin or superficial bladder cancer). 7. Uncontrolled medical conditions such as heart failure, myocardial infarction, uncontrolled hypertension, stroke or treatment of a major active infection within 3 months of randomization, as well as any significant concurrent medical illness that in the opinion of the Investigator would preclude protocol therapy. 8. Planned concomitant participation in another clinical trial of an experimental agent, vaccine, or device. Concomitant participation in observational studies is acceptable. |
