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   43871   clinical trials with a EudraCT protocol, of which   7290   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 main objective of this trial was to evaluate the therapeutic effect of duvelisib (IPI-145) administered to participants diagnosed with indolent non-Hodgkin lymphoma (defined as follicular lymphoma, marginal zone lymphoma [splenic, nodal and extranodal], or small lymphocytic lymphoma) whose disease was refractory to rituximab and to either chemotherapy or radioimmunotherapy.
    Protection of trial subjects
    This study was conducted in accordance with International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) Good Clinical Practice, and the principles of the Declaration of Helsinki, in addition to following the laws and regulations of the country or countries in which a study is conducted.

    Overall Response Rate (ORR) [1]
    End point description
    ORR, defined as the total percentage of participants who had a best overall response of either complete response (CR) or partial response (PR), was evaluated locally (investigator's assessment) according to the revised International Working Group (IWG) Response Criteria for Malignant Lymphoma. ORR is reported with a 2-sided 95% exact confidence interval. ORR was tested against the null (≤30%) by 1-sided exact binomial test at 0.025 level. The p-value (≤0.0001) was calculated by 1-sided exact binomial test with the null hypothesis that ORR ≤30%.

    An adverse event was defined as any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A TEAE was defined as any adverse event that emerged or worsened in the period from the first dose of study treatment to 30 days after the last dose of study treatment. A summary of serious and all other non-serious adverse events regardless of causality is located in the Reported Adverse Events module.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    08 Apr 2014
    - Added human immunodeficiency virus screening/history at Screening. - Added guidance regarding use of vaccines, specifically the prohibition of live and live attenuated vaccines prior to and during study treatment. - Prophylaxis for herpes simplex virus and herpes zoster virus was added as a requirement for all participants. In addition, cytomegalovirus (CMV) prophylaxis was added as a recommendation for participants with prior CMV infection that required treatment, and additional monitoring for reactivation was added as a recommendation for these participants. - Modified Exclusion #2 to prohibit any prior treatment with phosphoinositide-3-kinase (PI3K) inhibitors and to add prior treatment with Bruton’s tyrosine kinase (BTK) inhibitors to exclusion criterion. - The statistical design of the study was updated from the previously used precision-based method to a group sequential design in the hypothesis testing framework. - Primary objective and endpoint definition were corrected to ORR, with overall response defined as best response of CR or PR. - TTR was added as a secondary endpoint. - Baseline corrected QT interval (QTc) measurements using the Fridericia’s correction method exclusion criterion was changed from >480 milliseconds (ms) to >500 ms; treatment modifications (that is, dose interruptions/holds) were updated with treatment interruption for duvelisib-treated participants now based on new Grade 3 QTc >20 ms from baseline. - Exclusion criteria were added for certain cardiac events and for participants who have had gastric bypass or other procedures that may affect absorption of duvelisib. - The 25 mg once a day dose level was replaced with 10 mg BID for dose level -2. A new dose level of 5 mg BID (-3) was added. - Concomitant medication sections for antimicrobial prophylaxis, use of vaccines, immunosuppressants, PI3K and BTK inhibitors, and photosafety were added.
    30 Apr 2015
    - Changed to allow participants to continue to receive duvelisib treatment for an additional year after 13 cycles if they have documented evidence of response (CR or PR) or stable disease. This had been amended from the original language which required a CR or PR. - Changed to enroll approximately 80 follicular lymphoma participants, rather than at least 100. The amended estimate was based on the accrual pattern of the subtypes observed in the study. - Change to reflect that an independent data monitoring committee (DMC), rather than an internal DMC, was assembled to periodically review all available safety information and review efficacy data at the interim analysis.
    03 Nov 2015
    - Changed to state that participants who display evidence of clinical benefit after 1 year of treatment may continue to receive duvelisib until disease progression or unacceptable toxicity. This was amended from allowing participants to receive up to a total of 2 years of treatment. - The cautionary statements on concomitant use of cytochrome P450 substrates were strengthened. - An exploratory efficacy endpoint evaluating lymph node response rate was added.
