E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to show superiority of zoledronic acid as compared to control in the proportion of patients with at least one bone metastasis after 48 months of treatment. |
Dimostrare la superiorita' dell'acido zoledronico rispetto al controllo nella proporzione di pazienti con almeno una metastasi ossea dopo 48 mesi di trattamento. |
|
E.2.2 | Secondary objectives of the trial |
· to evaluate the effect of zoledronic acid on the time to the first bone metastasis irrespective whether symptomatic or not; · to evaluate the effect of zoledronic acid on overall survival; · to evaluate the effect of zoledronic acid on serum PSA doubling time; · to evaluate the effect of zoledronic acid on biochemical markers of bone turnover (selected centers only); · to evaluate the effect of zoledronic acid on bone mineral density at two and four years after randomization in patients receiving hormonal therapy at study entry (substudy in selected centers) |
1)valutare l`effetto dell`acido zoledronico sul tempo di comparsa della prima metastasi ossea,sintomatica o asintomatica; 2)valutare l`effetto dell`acido zoledronico sulla sopravvivenza globale; 3) valutare l`effetto dell`acido zoledronico sul tempo di raddoppiamento del PSA sierico; 4) valutare l`effetto dell`acido zoledronico sui marcatori biochimici di metabolismo osseo (solo nei Centri selezionati).5)- valutare l effetto dell acido zoledronico sulla densita` minerale ossea a due e quattro anni dalla randomizzazione in pazienti in trattamento ormonale (sottostudio realizzato solo nei Centri selezionati). |

E.3 | Principal inclusion criteria |
· Male patients aged 18+, ECOG = 0 (Karnofsky performance status > 90). · M0 prostate cancer patients who previously received local curative treatment (e.g. surgery, radiotherapy) or no local curative treatment. Duration between local curative treatment and starting of the study drug must not be longer than 6 months. · At least one of the following conditions must be present: Gleason Score 8-10; - pN+; - PSA ³ 20 at diagnosis. · Patients receiving androgen deprivation by orchiectomy or administration of GnRH analogue ± anti-androgens or no androgen deprivation. Hormone therapy regimen will depend on standard medical management of prostate cancer patients, i.e. when corresponding to standard medical management, patients on hormone treatment at study entry can later be withdrawn and patients not on hormone treatment at study entry can later start with androgen deprivation. Intermittent hormone treatment is allowed when corresponding to standard medical management. Patients should not be under hormonal ablation for longer than 6 months before the first study drug infusion. Neoadjuvant androgen deprivation is allowed as long as the duration between start of androgen deprivation and start of study drug is no longer than 6 months. · Life expectancy of > 6 months · Signed informed consent prior to initiation of any study procedure. |
- Pazienti maschi di eta` ≥ 18 anni, ECOG=0 (indice di performance di Karnofsky ≥ 90); - Carcinoma prostatico senza metastasi, precedentemente trattato localmente (chirurgia, radioterapia) oppure senza trattamento locale. Fra l inizio dei trattamenti locali e quello del prodotto in studio non devono essere trascorsi piu` di 6 mesi; - Almeno una delle seguenti condizioni deve essere presente: Gleason score 8-10, pN+, PSA ≥ 20 alla diagnosi - Pazienti sottoposti a deprivazione androgenica mediante orchiectomia o somministrazione di analoghi del GnRH con o senza antiandrogeni, oppure non sottoposti a deprivazione androgenica. Il trattamento ormonale sara` scelto sulla base della normale pratica clinica del centro; se ritenuto opportuno, il trattamento ormonale presente al momento dell entrata in studio potra` essere successivamente sospeso; inoltre, i pazienti non in trattamento ormonale all entrata in studio potranno successivamente essere sottoposti a deprivazione androgenica. Il trattamento intermittente e` ammesso quando corrisponde al trattamento medico standard. I pazienti non devono essere in deprivazione ormonale da oltre 6 mesi prima della prima dose del farmaco in studio. La deprivazione androgenica neoadiuvante e` ammessa solo se la sua durata prima dell inizio del farmaco in studio non supera i 6 mesi; - Aspettativa di vita > 6 mesi; - Consenso informato scritto prima dell inizio di qualsiasi procedura di studio |
|
E.4 | Principal exclusion criteria |
· Patients with known visceral metastasis or bone metastases in bone scan; · prior treatment with bisphosphonates; · chemotherapy to treat prostate carcinoma; · Anti-androgen monotherapy is not allowed; · use of other investigational drugs (drugs not marketed for any indication) within 6 months before start of study; · history of noncompliance to medical regimens and patients who are considered potentially unreliable or incapable of giving informed consent as judged by the investigator; · Abnormal renal function as evidenced by a calculated creatinine clearance < 30 ml/minute. Creatinine clearance (CrCl) is calculated using the Cockcroft-Gault formula. If serum creatinine is measured in micromol/l, the creatinine value in micromol/l should be multiplied with factor 0.0113 in order to obtain the creatinine value in mg/dL. For example: serum creatinine is 265 micromol/l x 0.0113 = 3 mg/dL. · Current active dental problems including infection of the teeth or jawbone (maxilla or mandibular); dental or fixture trauma, or a current or prior diagnosis of osteonecrosis of the jaw (ONJ), of exposed bone in the mouth, or of slow healing after dental procedures; · Recent (within 6 weeks) or planned dental or jaw surgery (e.g.. extraction, implants); ·history of other malignant neoplasm within previous five years with exception of nonmelanomatous skin cancer which has been satisfactorily treated; · other known concurrent, severe medical disorder jeopardizing the life of the patient in the immediate future (myocardial infarction in previous six months, angina pectoris despite treatment, uncontrolled severe arterial hypertension, progressive cardiac or respiratory failure) |
- Pazienti con metastasi viscerali o ossee alla scintigrafia; - Precedente trattamento con bisfosfonati; -Trattamento del carcinoma prostatico mediante chemioterapia; - Uso di altri farmaci sperimentali nei 6 mesi precedenti lo studio; - Storia di scarsa adesione a protocolli medici, oppure pazienti giudicati non affidabili o incapaci di fornire il consenso informato scritto, a giudizio dello sperimentatore; - Alterata funzionalita` renale evidenziata da una clearance della creatinina < 30 ml/minuto. La clearance della creatinina (CrCl) viene calcolata utilizzando la formula di Cockcroft-Gault. Se la creatinina sierica e` misurata in micromoli/l, il valore della creatinina in micromoli/l dovra` essere moltiplicato per il fattore di conversione 0.0113 in modo da ottenere il valore della creatinina in mg/dL. Ad esempio: creatinina sierica = 265 micromoli/litro x 0.0113 = 3 mg/dL; - Odontopatie attive comprese infezioni dei denti o della mascella o mandibola; trauma dentale o dell impianto, diagnosi di osteonecrosi della mascella o della mandibola, dell osso esposto, o di guarigione lenta dopo procedure odontoiatriche; - Chirurgia recente (entro 6 settimane) o programmata dei denti o della mascella o mandibola (ad es. estrazioni, impiantologia); -Storia di altre neoplasie maligne nei 5 anni precedenti, fatta eccezione per i tumori della cute non di tipo melanoma trattati con successo; - Altre gravi patologie che possano mettere a rischio la vita del paziente nel futuro immediato (infarto miocardico nei 6 mesi precedenti, angina pectoris incontrollata, ipertensione arteriosa grave non controllata, insufficienza cardiaca o respiratoria progressiva) |
