Summary

The purpose of this study is to assess the safety and efficacy of teverelix TFA in the treatment of advanced prostate cancer

Description

After being informed about the study and potential risks, all patients giving written informed consent will undergo an up to 7 day screening period to determine eligibility for study entry. On Day 0, patients who meet the eligibility requirements will be enrolled in an open-label manner and will receive a loading dose of teverelix TFA (one subcutaneous (SC) injection in the abdomen and one intramuscular (IM) injection in the buttock). Patients will then receive maintenance doses of teverelix TFA (one SC injection in the abdomen) at 4- or 6-weekly intervals up to week 24. The patients will return for a final assessment 4 weeks after their last maintenance dose injection.

The initial dosing regimen to be tested (Group 1) is:

Loading Dose = 120 mg teverelix TFA SC + 120 mg teverelix TFA IM Maintenance Dose = 120 mg teverelix TFA SC every 6 weeks

If this dosing regimen is unsuccessful (more than 2 (of 20) patients fail treatment) then recruitment to Group 1 will end and enrollment in Group 2 will open.

The dosing regimen that may be tested (Group 2) is:

Loading Dose = 180 mg teverelix TFA SC + 180 mg teverelix TFA IM Maintenance Dose = 180 mg teverelix TFA SC every 6 weeks

If this dosing regimen is unsuccessful (more than 6 (of 60) patients fail treatment) then recruitment to Group 2 will end and the study will be terminated.

Eligibility		Yes	No	Not Sure
Inclusion Criteria
	Is male, aged ≤80 years (≥18 years) at the beginning of the treatment period (Day 0)
	Has histologically proven advanced adenocarcinoma of the prostate (metastatic or non metastatic hormone-sensitive non curative), suitable for ADT
	Is treatment naïve for any of the following: a. GnRH analogues b. Androgen receptor antagonists, or c. Androgen synthesis inhibitors (e.g. abiraterone)
	Agrees to practice contraception during the entire study treatment period and for 3 months after the last dose of IMP is administered: a. Either by using double barrier contraception, b. or, is truly sexually abstinent, when this is in line with the preferred and usual lifestyle of the participant
	Has provided written (personally signed and dated) informed consent before completing any study-related procedure, which means any assessment or evaluation that would not have formed a part of his normal medical care
Exclusion Criteria
	Has abnormal screening and/or baseline laboratory values that suggest a clinically significant underlying disease, or the following laboratory values: a. Liver function test (aspartate aminotransferase [ASAT/SGOT], alanine aminotransferase [ALAT/SGPT]), or total bilirubin exceeding twice the upper limit of the normal (ULN) range b. Creatinine twice the ULN range c. Uncontrolled diabetes (HbA1c >7.5%) or previously undiagnosed diabetes mellitus with HbA1c >6.5%
	Has any contraindication to the use of teverelix TFA
	Has life expectancy of less than 1 year
	Has T levels <2.0 ng/mL at screening
	Has a medical history of bilateral orchidectomy
	Using any of the following prohibited treatments: a. Within 25 weeks prior to screening: dutasteride b. Within 12 weeks prior to screening: finasteride c. Current use of any of the following: i. Anti-androgen therapy, including T replacement therapy and 5α-reductase inhibitor treatment etc. ii. GnRH analogues, androgen receptor antagonists iii. Androgen synthesis inhibitors (e.g. abiraterone) iv. Any other medication or herbal product that may affect hormone levels and might, therefore, confound interpretation of the study results (e.g. St. John's wort)
	Has neurological disease, psychiatric disease, drug or alcohol abuse, which could interfere with the participant's proper compliance
	Has a history of myocardial infarction, unstable symptomatic ischaemic heart disease, any ongoing cardiac arrhythmias of grade >2 (chronic stable atrial fibrillation on stable anticoagulant therapy is allowed), thromboembolic events (e.g. deep vein thrombosis, pulmonary embolism, or symptomatic cerebrovascular events), or any other significant cardiac condition (e.g. pericardial effusion, restrictive cardiomyopathy) within 6 months before screening
	Has congenital long QT syndrome or ECG abnormalities at screening of: a. Q-wave infarction, unless identified ≥6 months before screening b. Fridericia corrected QT interval (QTcF interval) >480 msec. If QTcF is prolonged in a participant with a pacemaker, the participant may be enrolled in the study upon discussion with the project clinician c. If the QTcF interval is 450-480 msec, inclusive, in a participant with current use of medications with known effects on QT interval, the participant may be enrolled in the study following discussion with the Medical Lead
	Has known or suspected severe renal impairment
	Has a medical history of diagnosis of, or treatment for, another malignancy within 2 years before the first dose of IMP, or previous diagnosis of another malignancy with evidence of residual disease. Participants with nonmelanoma skin cancer or carcinoma in situ of any type are not excluded if they have undergone complete resection
	Is currently using Class IA (e.g. quinidine, procainamide) or Class III (e.g. amiodarone, sotalol) antiarrhythmic medications
	Has uncontrolled hypertension despite appropriate medical therapy (sitting BP of >180 millimetres of mercury [mmHg] systolic and >95 mmHg diastolic at 2 separate measurements taken no more than 60 minutes apart during the screening visit). Participants with isolated systolic BP measurements >180 mmHg may be rescreened. Participants with isolated systolic BP measurements 141 to 180 mmHg or isolated diastolic BP measurements ≥95 mmHg, although eligible, should be referred for further management of hypertension if indicated
	Has known, previously diagnosed human immunodeficiency virus (HIV) infection, active chronic hepatitis B or C, life-threatening illness unrelated to prostate cancer, or any serious medical condition that could, in the investigator's opinion, potentially interfere with participation in this study. Specific screening for chronic viral illness is at the discretion of the site and/or local Institutional Review Board (IRB)
	Has been exposed to another investigational drug within the 3 months prior to screening
	Has anticipated non-availability for study visits/procedures
	Plans to undergo surgery during the study period
	Known presence of hepatic metastases
