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 ).

    		 Confirmed Objective Response Rate (ORR) According to Response Evaluation Criteria in Solid Tumors (RECIST) Criteria [1]
    End point description
    The ORR is the percentage of participants whose best tumour response is either complete response (CR) or partial response (PR), according to the RECIST v1.0 criteria. The CR is defined as disappearance of all target lesions (TLs). The PR is defined as at least a 30% decrease in the sum of longest diameters (LD) taking as reference the baseline sum of LD. Percentage of participants with ORR is reported. The per-protocol (PP) population included all enrolled participants who completed the trial schedule and medication regime without any major deviations to the protocol.

    End point description
    PFS is defined as the time from first dose to the earlier date of radiologic progression (as per RECIST criteria) or death by any cause in the absence of objective progression. Those participants who were withdrawn from the study without disease progression were regarded as censored at their last evaluable RECIST assessment. Where participants had not progressed at the termination of the study, they were also regarded as censored at their last evaluable RECIST assessment. PFS was analyzed using Kaplan-Meier estimate. The PP population included all enrolled participants who completed the trial schedule and medication regime without any major deviations to the protocol.

    End point description
    ECOG performance status is used by researchers to assess how a participant's disease is progressing. The scores are: 0=Fully Active, able to carry out work without restrictions; 1=Restricted activity and able to carry out light work or sedentary nature; 2=capable of self-care but unable to carry out work activities; 3=Capable of only limited self-care, confined to bed or chair more than 50% of waking hours; 4=Completely Disabled, and totally confined to bed or chair; 5=Dead. Change in ECOG performance status was defined as improved (less than the baseline value), no change (same as at baseline), worsened (greater than the baseline value) or missing (score is missing or was not recorded at baseline). If no measurement was recorded at Cycle 1 Day 1, the change was calculated in relation to the last recorded ECOG value prior to Day 1. The PP population included all enrolled participants who completed the trial schedule and medication regime without any major deviations to the protocol.

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    26 Sep 2007
    Section 4 Objectives. A second dose group (100 mg bd) was introduced. After completion of the 400 mg bd dose group (40 participants), up to 24 participants (at least 6 of each BRCA type) were to be treated with 100 mg bd. The statistics section (5.7.3) was changed to provide justification for the amended sample size with the addition of the new cohort of participants. Section 5.3.1 Inclusion criteria. Inclusion criteria 2, 3 and 7 were each expanded for clarification. Section 5.3.2 Exclusion criteria. Exclusion criteria 1, 4, 5 and 6 were each expanded for clarification. Section 5.3.2 Exclusion criteria. Exclusion criterion 2 was modified. This criterion cross-refers to the section concerning restrictions in concomitant medication which was also changed. Some previously restricted drugs were to be allowed (specifically, fluvoxamine, fluconazole, fluoxetine, amiodarone, paroxetine, quinidine). Section 5.3.4 Discontinuation of participants from treatment. The original protocol stated that participants were to be discontinued from treatment if they had significant disease progression. The amendment clarified that the definition of progressive disease should be based on imaging / RECIST criteria and not mainly on tumour markers (if possible). Section 2.3.1.1 Independent Data Monitoring Committee. An IDMC was introduced.
    20 Mar 2008
    Section 4.2 Secondary objectives. The secondary endpoint Time to progression (TTP) was changed to progression-free survival (PFS). Section 5.1 Study Design. Blood sampling for peripheral blood mononuclear cells (PBMCs) was discontinued for new participants entering the study. Section 5.1 Study Design. Biochemistry assessments for amylase and lipase were added. Section 5.3 Selection of study population. The participant number was reduced (64 to 52), sites were added, and the recruitment period was lengthened. The statistics section (5.7.3) was changed to provide justification for the amended sample size. Section 5.3.2 Exclusion criteria. Exclusion criterion 3 was modified.
    04 Jun 2008
    Section 5.3 Selection of study population. The sample size was increased from ‘up to 26’ to ‘up to 27’ per cohort. Section 5.3.4 Discontinuation of participants from treatment or assessment. Participants in the 100 mg bd dose cohort could move to 400 mg bd, at the investigator’s discretion, if they had clinically significant progressive disease. Section 5.7.4 Interim analyses. Flexibility was added to the protocol to allow for a potential increase in dose in cohort 2 (100 mg bd). Informal interim monthly reviews of withdrawal rates from each cohort were introduced and if a statistically significantly higher withdrawal rate in the 100 mg bd dose group was observed, then participants in the 100 mg bd dose group were to be allowed to move to the 400 mg bd dose, at the investigator’s discretion.
    11 Feb 2009
    This amendment defined the end of study as 6 months post-LPI, or after approval of amendment 4, whichever was the later.
    19 Aug 2010
    1. The sponsor of the study was changed from KuDOS Pharmaceuticals Ltd., to AstraZeneca AB, with a change of address. The protocol was updated accordingly. 2. The sponsor project manager was changed. The protocol was updated accordingly. 3. Removed text specific to the previous protocol amendment (number 4) regarding visits done before the protocol was approved. 4. Updated the exclusion criteria to include 2 methods of contraception in combination rather than 1. 5. Updated the summary of Phase I data.
    26 Jul 2021
    Synopsis, Sections 3.1.1 Presentation of KU-0059436, 3.1.3 Packaging/Labelling of KU-0059436, 3.2 Dose, Route and Schedule of KU-0059436 Administration, 5.3 Table 3 Schedule of Assessments, and 6.1.3.5 Overdose and NEW Sections 3.3.3 Dose Modifications During the Continued Access Phase and 5.3.5 Patients in the Continued Access Phase: Addition of language regarding transition from capsule form to tablet form for those participants in continued access phase, including labelling, follow up, overdose and recommended capsule doses to equivalent tablet doses. Section 3.1.2 Storage/Stability of KU-0059436 Removal of text regarding KU-0059436 needing to be protected from light. Section 3.5.1 Medications That May NOT be Administered: Updated language on live/bacterial vaccines not being permitted while taking KU-0059436 (olaparib). Section 3.5.4 Contraception: Added language on contraception and length of time on contraception. Section 6.1.3.7 KU-0059436 (Olaparib) Adverse Events of Special Interest: Updated safety language regarding adverse events of special interest.

    Interruptions (globally)
    Were there any global interruptions to the trial? No

    Limitations and caveats
    Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
    The plasma concentration data was analysed using a population approach and polyadenosine 5’ diphosphoribose polymerase (PARP) inhibition data had already been obtained from Study D0810C00002. Hence no PK and PARP inhibition data are included.
