E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The two main objectives of the study are: ♦ To assess the efficacy of androgen deprivation therapy in treatment naïve patients with recurrent and/or metastatic, androgen receptor expressing, salivary gland cancers (SGCs). The primary measure of efficacy is progression-free survival. ♦ To describe the effect of androgen deprivation therapy in pretreated patients with recurrent and/or metastatic, androgen receptor expressing SGCs. The main measure of efficacy is response to treatment. |
|
E.2.2 | Secondary objectives of the trial |
1. Androgen receptor (AR) positive salivary duct carcinomas (SDCs) and adenocarcinoma not otherwise specified (NOS) will be investigated in order to: a) verify similarities/differences in terms of molecular and immunophenotypic alterations between SGC and the quoted prostate cancer (Pc) profiles. b) find out potential biomarkers to predict AR resistance to treatment in terms of progression free survival (PFS). c) perform comparative gene-expression and miRNA profiling between the AR-positive sensitive and resistant tumors. 2. AR negative SDCs and adenocarcinoma NOS will be biologically characterized, to generate hypotheses for the AR- signaling independent growth. 3. AR positive and negative cases, resulting from the screening for AR expression), will be compared in terms of gene-expression profiling and miRNA.

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
At patient registration step: - Histologically proven diagnosis of recurrent and/or metastatic salivary duct cancer; adenocarcinoma not otherwise specified (NOS); and androgen receptor expression level of = 6 in nuclei of neoplastic cells based on central review. Sufficient tissue must be available either from a historical sample or a new biopsy must be done as a part of this study and sent for central review for patients to be enrolled in both cohorts; - Presence of at least one uni-dimensional measurable lesion (target lesion) by CT-scan or MRI according to RECIST criteria version 1.1. A lesion previously treated with radiotherapy can be chosen as a target lesion only if progression in the respective lesion has been demonstrated during or following radiotherapy; - No actively bleeding tumor for patients who will receive carboplatin - Patients 18 years or older; - Performance Status ECOG 0-1; - Absence of any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial; - Before patient registration, written informed consent must be given.
At patient enrollment step: - Central pathology confirmation of androgen receptor expression - Adequate bone marrow function (within 2 weeks prior to treatment start): WBC ≥ 3.5/10^9L absolute neutrophil count ≥ 1,5x10^9/L hemoglobin > 10 g/dL or > 6.20 mmol/L platelet count ≥ 100x10^9/L - Adequate liver function (within 2 weeks prior to treatment start): AST < 2.5 times upper limit of normal ALT < 2.5 times upper limit of normal bilirubin < 1.5 times upper limit of normal - Adequate renal function (within 2 weeks prior to treatment start): serum creatinine level (≤ 1.3 mg/dL) calculated creatinine clearance ≥ 60 mL/min based on the standard Cockcroft and Gault formula. - Adequate cardiac function as demonstrated by a clinically normal 12 lead ECG (triplicate method) and a normal left ventricular ejection fraction (LVEF) ≥ 50% (within 2 weeks prior to treatment) by echocardiography of MUGA as per national guidelines. - Women of child bearing potential must have a negative serum pregnancy test within 1 week prior to the first dose of study treatment and prior to the start of every cycle; - Patients of childbearing / reproductive potential should use adequate birth control measures, as defined by the investigator and the Clinical Trials Facilitation Group (CTFG) guidelines, during the study treatment period based on national guidelines and clinical judgement of participating investigators and for at least 6 months after the last study treatment. A highly effective method of birth control is defined as those which result in low failure rate (i.e. less than 1% per year) when used consistently and correctly; women should not breastfeed a baby while on this study. - The highly effective methods of contraception include total sexual abstinence, combine (estrogen and progestogen containing) or progestogen-only hormonal contraception associated with inhibition of ovulation, intrauterine device (IUD), intrauterine hormone-releasing system (IUS), bilateral tubal occlusion, and vasectomized partner. - In case of male participants, in addition to the above mentioned methods, men should use condom. - Those who will receive ADT should be advised to use non-hormonal contraception. - No participation in another interventional clinical trial in the preceding 4 weeks prior to enrolment
Specific for Cohort A: No previous chemotherapy for recurrent/metastatic disease (previous chemotherapy given concomitantly with RT in the past is allowed, including cisplatin but it should be completed at least 6 months before enrolment).
Specific to Cohort B: Patients who received chemotherapy for recurrent and metastatic disease and subsequently progress will be included in this cohort.

|
E.4 | Principal exclusion criteria |
- Pregnant or lactating women - Actively bleeding tumor if the patient is intended to be treated with carboplatin - Cardiac abnormalities as demonstrated by: - recent history of congestive heart failure - unstable angina within the past 3 months - cardiac arrhythmia - myocardial infarction - congenital long QTc prolongation - stroke - TIA within the past 6 months; - Previous cardiac toxicity induced by another anthracycline or previous exposure to maximum cumulative dose of another anthracycline if the patient is intended to be treated with doxorubicin - History of allergic reactions attributed to compounds of similar chemical or biological composition to cis/carboplatin, paclitaxel, doxorubicin, bicalutamide or triptorelin; - Concomitant medications with terfenadine, astemizole, cisaprid - Use of phenytoin - Active second malignancy during the last five years except non melanomatous skin cancer or carcinoma in situ of the cervix; - Patients with bone disease or brain disease as the sole disease site; brain metastases are allowed in the case of systemic disease, but must have been treated at least 4 weeks before enrolment and must be stable thereafter; - Patients who received vaccine for yellow fever - Patients with an immediate family member (e.g. spouse, parent/legal guardian, sibling or child) who is an investigational site or Sponsor staff directly involved with this trial, unless prospective IRB approval (by chair or designee) is given allowing exception to this criterion for a specific subject

E.5 End points |
E.5.1 | Primary end point(s) |
Cohort A (treatment naïve patients): Progression-free survival according to Response Evaluation Criteria In Solid Tumors (RECIST) criteria version 1.1 and/or Prostate Cancer Clinical Trials Working Group (PCWG2) (2007) for bone lesions, or death, whichever comes first.
Cohort B (pretreated patients): Best overall response defined according to RECIST v 1.1. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
During treatment RECIST criteria evaluation will be performed at week 8, 16 and 28 and every 12 weeks thereafter (+/- 1 week) through head and neck and thorax CT scan or head and neck MRI. PCWG2 evaluation will be performed at the same time-points through bone scans.
After the end of treatment and up to disease progression imaging will be done every 12 weeks and other investigations should be done if clinically indicated or based on institutional standard practice. |
|
E.5.2 | Secondary end point(s) |
For treatment-naïve patients: - Best Overall Response defined according to RECIST v 1.1 - Overall Survival - Toxicity
For pre-treated patients: - Progression Free Survival - Overall Survival - Toxicity |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
The time-points for evaluation of Best Overall Response and Progression Free Survival are the same as for the primary endpoint; at week 8, 16 and 28 and every 12 weeks thereafter (+/- 1 week). In addition overall survival will be assessed through long-term follow-up once every year. Toxicity will be assessed prior to each treatment cycle and at the end of treatment.
