E.1.2 Medical condition or disease under investigation |
E.1.2 | Version | 9.1 |
E.1.2 | Level | LLT |
E.1.2 | Classification code | 10033363 |
E.1.2 | Term | Paget's disease of bone |

E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary efficacy objective is to show that patients with Paget´s disease of bone who had responded to zoledronic acid and later experienced a relapse can successfully have their total serum alkaline phosphatase (SAP) normalized within 6 months after a single 5 mg re-treatment dose of Aclasta. This objective will be demonstrated if at least 60 % of patients have their total SAP normalized within 6 months. |
|
E.2.2 | Secondary objectives of the trial |
- Determine the relative change in SAP levels at 3 months and 6 months following re-treatment with Aclasta - Collect information pertaining to the diagnosis of relapse used by practicing physicians that will define and support re-treatment guidelines for Paget´s disease of bone in patients who have previously responded to zoledronic acid treatment - Determine the adverse event profile of patients who receive a re-treatment dose of Aclasta. A safety objective will be demonstrated if the incidence of transient post-dose symptoms (PDS) is reduced by 20% relative to the incidence in the core study |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Patients must give written informed consent to participate in the study - Male or female patients who were randomized to receive zoledronic acid in the CZOL446K2304 (previously referred to as CZOL446H2304) or CZOL446K2305 (previously referred to as CZOL446H2305) pivotal studies and met the definition of responder at the 6 month post-dose visit - Confirmed relapse of Paget´s disease of the bone based on investigator´s assessment through one or more of the following: SAP that is above the ULN, bone scan consistent with relapse of Paget´s disease of bone, and/or worsening of clinical symptoms (e.g., bone pain or compression symptoms) |
|
E.4 | Principal exclusion criteria |
- A patient treated with Aclasta, who relapsed during the EOP and was treated with anti-resorptive bisphosphonate or calcitonin therapy within the past 12 months - Hypersensitivity to any drug within the class of bisphosphonates - Patients with a new diagnosis or active treatment for malignancy (other than basal cell or squamous cell skin cancer) less than or equal to 12 months prior to study entry - Patients with suspected or proven metastases at time of re-treatment - Patients who are unlikely to be able to complete the study or comply with the visit schedule and required assessments due to cancer, non-skeletal metastases or paraneoplastic syndrome or their ongoing/planned treatments - Specific exceptions to the cancer exclusion (within 12 months prior to re-treatment). Patients may be included if: Basal cell or squamous cell carcinoma of the skin, colonic polyps with non-invasive malignancy have been removed, ductal Carcinoma in-situ (DCIS) has been surgically removed, carcinoma in-situ (CIS) of the uterine cervix has been surgically removed - Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until termination of gestation, confirmed by a positive urine test - Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant including women whose career, lifestyle, or sexual orientation precludes intercourse with a male partner and women whose partners have been sterilized by vasectomy or other means, UNLESS they are using two birth control methods. The two methods can be a double barrier method or a barrier method plus a hormonal method. Adequate barrier methods of contraception include: diaphragm, condom (by the partner), intrauterine device (copper or hormonal), sponge or spermicide. Hormonal contraceptives include any marketed contraceptive agent that includes an estrogen and/or a progestational agent - Reliable contraception should be maintained throughout the study and for 60 days after study drug discontinuation - Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or six months of spontaneous amenorrhea with serum FSH levels >40 mIU/ml and estradiol <20 pg/ml or have had surgical bilateral oophorectomy (with or without hysterectomy) at least six weeks prior to visit 2. In the case of oophorectomy alone, classification of a woman as post-menopausal would occur when her reproductive status has been confirmed by follow up hormone level assessment - Any disease or therapy which will interfere with the procedures or data collection of this trial - Patients with active (symptomatic or asymptomatic) iritis, uveitis or episcleritis - Calculated creatinine clearance <35 ml/min at screening visit - Serum calcium level <2.07 mmol/L - Active primary hyperparathyroidism, hyperthyroidism, hypoparathyroidism or hypothyroidism No additional exclusions may be applied by the investigator, in order to ensure that the study population will be representative of all eligible patients |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy objective is to show that patients with Paget´s disease of bone who had responded to zoledronic acid and later experienced a relapse can successfully have their total serum alkaline phosphatase (SAP) normalized within 6 months after a singe 5 mg re-treatment dose of Aclasta. This objective will be demonstrated if at least 60% of patients have their total SAP normalized within 6 months. |
