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   43851   clinical trials with a EudraCT protocol, of which   7283   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 ).

    General information about the trial
    Main objective of the trial
    The primary objective was to assess the overall response rate and to evaluate the efficacy and safety of idelalisib (IDELA; GS-1101) in participants with previously treated indolent Non-Hodgkin Lymphoma (iNHL) that was refractory both to rituximab and to alkylating-agent-containing chemotherapy. Eligible participants initiated oral therapy with idelalisib at a starting dose of 150 mg taken twice per day. Treatment with idelalisib continued in compliant participants as long as the study was still ongoing and the participants appear to be benefiting from treatment with acceptable safety.
    Protection of trial subjects
    The protocol and consent/assent forms were submitted by each investigator to a duly constituted Independent Ethics Committee (IEC) or Institutional Review Board (IRB) for review and approval before study initiation. All revisions to the consent/assent forms (if applicable) after initial IEC/IRB approval were submitted by the investigator to the IEC/IRB for review and approval before implementation in accordance with regulatory requirements. This study was conducted in accordance with recognized international scientific and ethical standards, including but not limited to the International Conference on Harmonization guideline for Good Clinical Practice (ICH GCP) and the original principles embodied in the Declaration of Helsinki.

    Notes
    [1] - The number of subjects at this milestone seems inconsistent with the number of subjects in the arm. It is expected that the number of subjects will be greater than, or equal to the number that completed, minus those who left.
    Justification: 70 participants with disease progression is a subcategory for the number of participants who completed the TP overall.
    [2] - The number of subjects at this milestone seems inconsistent with the number of subjects in the arm. It is expected that the number of subjects will be greater than, or equal to the number that completed, minus those who left.
    Justification: 9 participants who died during the study is a subcategory for the number of participants who completed the TP overall.

    Notes
    [3] - The number of subjects starting the period is not consistent with the number completing the preceding period. It is expected the number of subjects starting the subsequent period will be the same as the number completing the preceding period.
    Justification: 54 of 79 participants who completed the TP entered the Long-term Follow up Period. 30 additional participants who discontinued the TP also joined the Long-term Follow-up Period. Therefore, a total of 84 participants entered the Long-term Follow up Period.

    Overall Response Rate [1]
    End point description
    Overall response rate (ORR) was assessed based on the International Working Group Revised Response Criteria for Malignant Lymphoma (Cheson, 2007), and was defined as the percentage of participants achieving a complete response (CR) or partial response (PR; or minor response [MR] for participants with WM) as assessed by the study independent review committee (IRC). CR was defined as the complete resolution of all disease-related radiological abnormalities and the disappearance of all signs and symptoms related to the disease. PR was defined as a ≥ 50% reduction in the sum of the products of the longest perpendicular diameters of all index lesions, with no new lesions. For WM only, response was defined as a reduction in immunoglobulin M (IgM) of ≥ 50% decrease for PR, and ≥ 25% decrease for MR; no increase from baseline in the sum of the products of the longest perpendicular diameters of all index lesions, with no new lesions or signs and symptoms of active disease (Owen, 2013)

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    22 Dec 2010
    • Clarified inclusion criteria for participants with Grade 3 FL to enroll only participants with Grades 1, 2, or 3a FL (not Grade 3b), ie, only participants with indolent FL. • Amended storage and stability to allow brief excursions of IDELA down to 5°C. • Clarified the response definition in the event that PET scans were obtained for participants with a PR
    24 Jan 2011
    • Amended inclusion criteria to ensure all participants were of legal age (≥ 18 years of age) at the time of entry into the study. • Removed the statement that idelalisib would be shipped at controlled room temperature, as this was not required.
    23 Apr 2012
    • Updated toxicology section to include findings available from 13-week toxicology studies. • Included a new section to provide new reproductive toxicity findings received from a definitive embryo-fetal development toxicity study. • Provided clarification regarding the inclusion of participants with SLL to state that the allogeneic lymphocyte cytotoxicity must be ≤ 5 × 10^9/L at the time of diagnosis and at the time of study entry. This clarification was made to ensure that participants with CLL were excluded. • Clarified the inclusion criteria regarding presence of radiographically measurable lymphadenopathy description and included a requirement for the length of longest perpendicular diameter. This provided enhanced clarity regarding the definition of measurable disease for study inclusion. • Revised inclusion criteria to ensure resolution of all acute toxicities to Grade ≤1 before the initiation of study treatment (exception of alopecia, neurotoxicity, and bone marrow parameters with resolution to Grade ≤ 2). • Removed the treatment stratification enrollment limit for participants who had received prior bendamustine. • Further defined the criteria for lesion selection and tumor response. This aligned the protocol with central imaging methods. • Provided time window surrounding the collection of PK samples to minimize deviations. • Added the requirement for collection and consideration for overall response of IgM serum monoclonal protein levels assessed by serum protein electrophoresis (SPEP) for participants with WM. • Included the provision “as allowed by local law” in the event of potential transition of participants from study treatment to commercial supply, should study drug become approved in the country in which the participant lives. • Changed the Stage 1 ORR analysis to be based on investigator response assessment instead of IRC assessment.
    23 May 2013
    • Established storage of biological samples (with participant’s informed consent) for future studies. • Clarified that final efficacy analysis occurs ≥ 24 weeks after the last participant enrolls. • Aligned the clinical response section with the criteria for the IRC. • Removed stratification analysis. • Revised dose modifications to no longer include reductions below 100 mg BID (based on PK data and exposure-response analysis for safety and efficacy). • Updated the pregnancy risk language, based on current animal studies data.
    18 Jul 2013
    • Modified the definition of SAE to exclude untoward medical occurrences which resulted in death due to disease progression. • Modified the definition of SAE to include CLL progression or death due to CLL progression only if assessed that study drug caused or contributed to the disease progression.
    28 Oct 2014
    • Updated the general information on idelalisib to reflect approval status in the United States and European Union • Align the following information with Investigator’s Brochure Edition 11 -Guidance to investigators for evaluation, intervention, and drug interruption/discontinuation for specific adverse events (AEs) -Information regarding the interaction of idelalisib with CYP3A inhibitors, inducers, and substrates
    25 Mar 2016
    • Updated the safety information and guidelines for toxicity management to be consistent across idelalisib study protocols. These changes included mandated prophylaxis for Pneumocystis jirovecii pneumonia (PJP), cytomegalovirus (CMV) surveillance, and increased monitoring. • Removed references to 75 mg tablets, as this dose strength was no longer formulated
    22 Aug 2016
    • Updated the recommended and required guidelines for toxicity management to be consistent across idelalisib study protocols• Updated the recommended and required guidelines for toxicity management to be consistent across idelalisib study protocols
    13 Oct 2016
    • In order to provide clear guidance for idelalisib administration in the event of pneumonitis, the language around actions to be taken was revised.
    23 Nov 2016
    • It was a France-only version which included additional information, per the request of the health authority, concerning discontinuation of idelalisib following an event of Stevens-Johnson syndrome (SJS) or toxic epidermal necrolysis (TEN) and management of co-administered medications.
    05 Sep 2017
    • Organizing pneumonia emerged as a potential safety signal during Gilead routine signal detection monitoring. This risk was added to the protocol.
