Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

    • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   44338   clinical trials with a EudraCT protocol, of which   7368   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    Recruitment
    Recruitment details
    		 This multinational, multicenter study was conducted at 97 contracted sites; 86 sites screened partcipants & 71 sites randomized participants in a total of 9 countries: Belgium (5 sites), Bulgaria (4 sites), Germany (2 sites), Hungary (7 sites), Poland (8 sites), Romania (6 sites), Ukraine (6 sites), the United Kingdom (2 sites) & Japan (31 sites).

    Pre-assignment
    Screening details
    		 After initial screening, eligible subjects enrolled into a non-medicated observational period, which included at least one complete menstrual cycle. After the observational period patients who met selection criteria were randomized into Part 1 of the study. Overall, 912 subjects were screened, 372 failed screening and 540 subjects were randomized.

    The study drug, except for open-label active control (leuprorelin acetate), was packed using a double-blind method. All participants took 3 tablets once daily in the morning of which none, one, two or all tablets were placebo (15 mg group: 3x5 mg, 10 mg group: 2x5 mg and 1 placebo, 5 mg group 1x5 mg and 2 placebo, 3 mg group: 3x1 mg, placebo group: 3 placebo). All tablets were identical. Participants randomized to open-label leuprorelin acetate received open-label injections only.

    		 Change from Baseline to the End of Treatment (EoT) (12 Weeks) of the Mean Numeric Rating Scale (NRS) Pain Score for Overall Pelvic Pain (Dysmenorrhea and Non-Menstrual Pelvic Pain) [1]
    End point description
    Pelvic pain measured daily by participants in an e-diary using NRS (scale 0 – 10, where 0 anchors ‘no pain’ & 10 ‘worst pain you can imagine’). Score of 1-3 represented ‘mild pain’ (nagging, annoying, interfering little with Activities of Daily Living [ADL]), 4-6 ‘moderate pain’ (interferes significantly with ADL), & 7-10 ‘severe pain’ (disabling, unable to perform ADL). Overall pelvic pain calculated as the mean of the NRS scale scores from the last 28-day period (whole menstrual cycle, including menstrual & nonmenstrual bleeding days) before each visit. Analysis population consisted of Full Analysis Set 1 (FAS1), which consisted of all randomized participants who received at least 1 dose of double-blind study medication (placebo or ASP1707) or at least 1 dose of leuprorelin acetate & who had a primary NRS pain score for overall pelvic pain at baseline & at least 1 evaluable post-baseline NRS pain score for overall pelvic pain, defined as having at least 14 days of pain score.

    [1] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.

Score of 1-3 represented ‘mild pain’ (nagging, annoying, interfering little with Activities of Daily Living [ADL]), 4-6 ‘moderate pain’ (interferes significantly with ADL), & 7-10 ‘severe pain’ (disabling, unable to perform ADL). Dysmenorrhea pelvic pain was calculated as the mean of the NRS scale scores from the menstrual bleeding days within the 28-day period. A score of 0 was applied if there was no menstrual bleeding during the 28-day period. Analysis population consisted of the FAS1.

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    05 Dec 2012
    -Spermicidal foam/gel/film/cream/suppository and occlusive cap were removed from inclusion criterion 6 because they are no longer acceptable nonhormonal contraceptive methods. According to the World Health Organization (WHO), spermicidal foam/gel/film/cream/suppository can increase the risk for certain sexually transmitted infections (including human immunodeficiency virus) and can cause local irritation of mucosal surfaces. In addition, spermicidally lubricated condoms do not have increased contraceptive efficacy compared to condoms without spermicide. Because of this, spermicidal foam/gel/film/cream/suppository is difficult to obtain or not available in many countries. Occlusive cap alone is not considered to be an effective contraceptive. -Total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), and triglycerides were added to the planned biochemistry tests because lipid changes had been added to the ASP1707 developmental risk management plan as a potential risk requiring monitoring in clinical studies. This did not change the amount of blood taken from the patients at any visit. -Administrative changes and typographical corrections were made.
    02 Dec 2014
    -The duration for use of non-hormonal contraceptive methods after the last dose was updated from 12 weeks to 42 days to align with the period during which pregnancies had to be reported. This update did not change the benefit/risk ratio for patients. -Dunnett’s test was added to appropriately adjust the comparisons of the active dose groups against placebo. -The database cutoff, which was planned after the last follow-up visit, was to be implemented after the EoS visit instead. These outputs were final and were used for the main analyses, including primary and all secondary efficacy analyses. The only data to be collected after this release would be in a limited number of patients that had completed the EoS visit but not yet the follow-up visit. This amendment only affected the timing of the analyses, and was not a formal interim analysis. -The planned study period was extended due to delayed recruitment. -The period for collection and follow-up of serious adverse events (SAEs) was made consistent throughout the protocol. -The updated Summary of Product Characteristics (SmPC) of leuprorelin acetate was added. The changes had no significant impact on the safety or physical or mental integrity of the patients, on the scientific value of the trial, on the conduct or management of the trial or on the quality or safety of any investigational medicinal products (IMP) used in the study. -Administrative changes and typographical corrections were made.
