E.4 | Principal exclusion criteria |
1. Post-menopausal status or (vasomotor) symptoms indicating upcoming menopause 2. Anti Mullerian Hormone (AMH) measurement at screening visit <0.03 ng/ml. 3. Patients who are pregnant or lactation, or who have an active desire to have children, pregnancy or breast-feeding during the clinical study 4. A history of osteoporosis or osteoporosis determined by DEXA-scan at screening (T score ≤ -2.5) 5. Patients diagnosed with a clinical depression and is or has been treated with antidepression medication. 6. Patients known with a prolongated QT time or who use medicinal products leading to a QT prolongation including, but not restricted to: class IA (e.g. quinidine, disopyramide) or class III (e.g. amiodarone, sotalol, dofetilide, ibutilide) antiarrhythmic medicinal products, methadone, moxifloxacin and antipsychotics. 7. Hypersensitivity to leuprorelin or other GnRH analogues, to polylactic acid or poly(D,L-lactide-co-glycolide) (1:1) 8. Patients with epilepsy which is not well-controlled (defined as manifestation of >= 1 seizure in the last 12 months). 9. Patients with a confirmed hormone independence carcinoma. 10. Liver transplantation or liver surgery expected within 1.5 years, to the discretion of the study doctor 11. Use of hormonal oral contra-conception containing estrogen and/or progesterone. In contrast, a hormone containing uterine device is not an exclusion criteria. 12. Contra-indications for MRI assessments (such as implants) or not able or willing to undergo MRI scan for other reasons (e.g. claustrophobia, profound obesity) 13. Kidney transplantation or chronic use of immunosuppressive agents (such as cyclosporine, mycophenolic acid, tacrolimus but not prednisolone) for other indications 14. Severe hypertension, defined as a systolic blood pressure >160 mmHg and/or diastolic blood pressure > 100 mm Hg. 15. Clinically significant, uncontrolled medical condition that, in the opinion of the investigator, would put the safety of the patient at risk through participation, or which would affect the efficacy of safety analysis if the condition exacerbated during the study, or that may significantly interfere with study compliance, such as, but not restricted to, recurrent cholangitis, recurrent ascites or hepato-venous outflow obstruction 16. Participation in other clinical trials or treatments with other IMPs and its relevant metabolites or previous therapies, whose toxicity (may) overlap with that of this studies IMP and its relevant metabolites within five times the half-life of the drug and/or metabolites (whichever is longer). 17. Participation in other interventional studies at the same time.
Exclusion criteria related to the historical MRI or CT scan to determine liver growth before start of the study - Start or stop of liver volume reducing therapy (medication e.g. somatostatin analogues or surgical interventions) in the period between the historical scan and the baseline MRI scan; - The historical MRI or CT scan is performed <3 months after start or stop of a somatostatin analogue or surgical volume reducing therapy.

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome is the livergrowth, in percent per year, calculated from BL till t=1.5 years, compared between the direct start groep (receiving leuproreline treatment in this period) and the delayed start group (serving as a control group). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
At the end of the trial, the primary outcome will be analyzed, using the calculated liver growth in percent per year during the first 18 months of the trial, compared between the direct start group and the delayed start group. |
|
E.5.2 | Secondary end point(s) |
1. Polycystic liver disease related complaints, using the validated PLD Questionnaire (8). The change in the score on the PLD Questionnaire (Δ PLD-Q score) will be compared between patients in the direct start group and the delayed start group after 18 months of treatment (Δ BL-18 months in the direct start group versus Δ BL-18 months in the delayed start group) 2. Liver growth rate (in % per year) compared within individuals before start of treatment and during treatment (a paired analysis of growth rates; in the direct start group of historical growth versus growht during the frist 1.5 years of treatment, and in the delayed start group between the first 1.5 years of the trial without treatment and the next 1.5 years of the trial with treatment. Exploratory outcomes: - liver volume, compared between the direct and delayed start groep after 1.5 years - estrogen levels, compared at BL, 3 months after start treatment, 1.5 years, 21 months and 3 years - acute effects of the treatment, using the MRI scans 6 months after start of treatment - safety and toleratability, incidence of (serious) adverse events, bonedensity measured using DEXA-scans, drop-out rate - Quality of life, assessed by het SF-36 and BD-II - menopause related complaints, assessed by the MENQOL-questionnaire In patients with polycystic kidney disease - growth rate of kidney volume in the first 1.5 years, compared between the direct start group and delayed start group - growth rate of kidney volumes, compared within individuals, before start of treatment and during treatment - acute effects of the treatment, using the MRI scans 6 months after start of treatment - change in renal function in the first 1.5 years between direct and delayed start group |
