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   43858   clinical trials with a EudraCT protocol, of which   7284   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 ).

    Determination of MTD/RP2D of CFG920 by DLTs occurring in first cycle [1]
    End point description
    4 dose levels of CFG920 (50 mg bid, 100 mg bid, 150 mg bid, 200 mg bid) were investigated in the dose escalation part of the study. 150 mg bid was excluded from the candidate doses of maximum tolerated dose (MTD)/ recommended phase ll dose (R2PD) as only 4 subjects were eligible for dose determining set (DDS) at this dose level. The RP2D selected was to be either the MTD or a dose below the MTD based on safety & pharmacokinetic/pharmacodynamic considerations. DLTs - dose limiting toxicities: by primary system organ class, preferred term & treatment group per DDS (consisted of all subjects from the safety set who either met the minimum exposure criterion & had sufficient safety evaluations, or had experienced a DLT during cycle 1 .

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    21 Aug 2012
    Amendment 1 was issued prior to enrollment of patients into the study. The main purpose of this amendment was to incorporate changes that Novartis has agreed to as per the agreement with the U.S. Food and Drug Administration. Eligibility Criteria To better define the eligible patient population, more specific inclusion requirements for prior treatment with docetaxel and ABI were added. Due to plausible mechanistic toxicities, laboratory criteria for potassium were added. To further define the DLT criteria for thrombocytopenia, additional details were included with regard to bleeding. Due to potential for mechanistic toxicities, additional dose modification, toxicity monitoring, and toxicity management guidance were added. To modify dose escalation criteria, the language in the guidelines was revised. Following reviewer recommendation, the starting dose was reduced to 50 mg bid.

    Amendment 2: To improve site and patient compliance and protocol execution, PD assessment was included as an exploratory endpoint. To address emerging data and to inform future decisions, a change from baseline of 30% decline in PSA was added as a secondary endpoint. To assess genetic abnormalities that were thought to be important in cancer, the collection of tumor biopsy specimens was added as an exploratory endpoint. With the addition of the mandatory tumor collection at Screening, receiving any additional tissue was not likely. To address the ensuing limited availability of paired fresh tissue biopsies, the optional fresh pre and post dose biopsies that were to be used to assess the suppression of AR signaling in tumor tissue and potential correlations with clinical outcomes and investigate the change in tumor androgens were eliminated. To allow for a better defining of progression per radiological assessment, the secondary Phase II endpoint to assess efficacy at MTD/RP2D via radiological progression free survival is renamed to radiological time to progression. To assess genetic abnormalities that are thought to be important in cancer, the requirement to collect tumor tissue was added to the inclusion criteria. To prevent premature discontinuation of patients from treatment and thus allowing the continued exploration of higher safe doses of CFG920, the management of blood bilirubin toxicity was revised to be in line with the management of toxicity of other molecules of the same class. To allow for better characterizing toxicity, the use of the adrenocortical insufficiency was changed to mineralocorticoid imbalance. To allow for more frequent assessment of plasma renin activity (PRA), the guidance for the management of adrenocortical insufficiency/ mineralocorticoid imbalance was revised. Because of its potential androgen receptor agonist activity, spironolactone was added as a prohibited medication.

    Amendment 3: Given the lack of evidence from preclinical studies of a difference in the clinical benefit between these primary and secondary ABI resistant CRPC arms, these two arms were combined into a single ABI resistant CRPC arm (Arm 2) in the Phase II part of the study. A supportive sub-group analysis to further investigate the effect of primary and secondary ABI resistance on CFG920 activity was to be performed retrospectively. Patient numbers were adjusted to match these changes. Because of the potential hyperglycemic effects of prednisone, glucose and HbA1c control (inclusion criteria) and monitoring of glucose levels (DLT and dose modification criteria) were added for patient safety. The DLT criteria were modified to allow for observation of possible hyperglycemia with the control of blood sugar prior to declaration of a DLT. In addition, the dose modification criteria were revised to provide guidance on the management of hyperglycemia as well as the clinical management of the discontinuation of prednisone. Monitoring frequency of PRA was revised to monitor potential changes in plasma renin activity (PRA) within the first five cycles of CFG920 initiation or dose modification. As part of protocol amendment 2, androstenedione was removed from the hormonal assessments. To ensure alignment within the protocol, androstenedione was also removed from the efficacy evaluation section.

    Amendment 4: In response to the request from Health Authorities, the inclusion criterion for ABI naïve patients in the Phase II part of the study was revised to include patients’ refusal of ABI as follows: no prior treatment with CYP17 inhibitors (ABI, ketoconazole, etc.) or enzalutamide, and refused ABI. Erstwhile data from the ongoing trial indicated that treatment with CFG920 could lead to increased risk of thrombocytopenia. To assess the potential effects of CFG920 on myeloid development, including that of megakaryocytes, the collection of a bone marrow biopsy and aspirate in patients who present with grade 3 or 4 thrombocytopenia was added. The interim analysis evaluated the PSA response, defined as a ≥ 50% reduction in PSA from baseline to ≥ 12 weeks of treatment that was confirmed 4 weeks later. As such, the timing of the interim analysis was revised to be performed after patients had completed at least 16 weeks of treatment.

    Amendment 6: Introduced a reduced visit schedule to address patients continuing beyond the study data cut off for the primary analysis (15-Aug-2014). Added the date of the data cutoff for the primary clinical study report (CSR). For all efficacy, safety and tolerability, and laboratory evaluation assessments, added the modified collection time points for patients following the reduced visit evaluation schedule. Clarified that the end of treatment collection would not be performed for patients following the reduced visit evaluation schedule. For all efficacy, safety and tolerability, and laboratory evaluation assessments, added the modified collection time points for patients following the reduced visit evaluation schedule.

    Interruptions (globally)

    Limitations and caveats

    Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
    Since patient enrollment was stopped after the completion of the dose-escalation part (Phase I), all analyses related to the phase II part were not conducted. Recruitment halt was implemented after completion of Phase I.
