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   44403   clinical trials with a EudraCT protocol, of which   7413   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.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    21 Mar 2014
    Amendment #1: - Change to Section 10.4 Safety Monitoring to address FDA's issue in IND review * Added text that if Grade 3 or higher adverse events occur in any subject in a cohort then safety information will be provided to FDA for review prior to proceeding with dose escalation * Added text on how dose selection will occur for Stage 2 * Added text to provide stopping rules for the study
    31 Mar 2014
    Amendment #2: - Change to Section 10.4 Safety Monitoring to address FDA's issues in IND review: * The safety data will be reviewed by a clinical study monitoring team * Added text that AEs of Grade 3 or higher will be reviewed carefully with respect to number and causality when determining if dose escalation is appropriate * Added text on how dose selection will occur for Stage 2 * Added text to provide stopping rules for the study
    04 Apr 2014
    Amendment #3: - Change to Section 19.1 Study Schedule of Events to correct superscript and footnotes and associations for #5-11: * Removed Pre-dose and Screening ECG * Replaced Post-dose ECG with ECG * Corrected footnote associations for superscripts 6-11
    16 Apr 2014
    Amendment #4: - Change to Section 7.4 has been amended to remove the limitation on the stopping rule to “treatment-related” adverse events and now includes all adverse events. Rationale: The inclusion of all adverse events in safety evaluations was agreed with FDA in prior discussions. The “treatment-related” qualifier was inadvertently retained.
    20 Jul 2015
    Amendment #8: - Changes to Sections 2, 7.1, 7.2, 7.4, 10.1, added third stage to the study allowing patients with response to therapy to continue on study treatment for an additional 4 weeks or 12 weeks depending on the disease type. Rationale: Stage 3 was added for extension of drug treatment should subjects show response to therapy - Changes to Section 2: Increase Number of Study Centers from 35 to 50. Rationale: With such a rare patient population, this is to help reach enrollment of 89 subjects - Changes to Sections 2, 7.1.2: Increase duration of the Study from 20 months to 48 months. Rationale: Current feasibility shows enrollment <1 subject/site/year. Increasing study duration helps with reaching enrollment goal of 89 subjects and to accommodate for increasing treatment period of aHUS subjects and the addition of Stage 3 - Changes to Sections 2, 10.2: Increase number of subjects to be enrolled from 29 to 89. Rationale: Addition of patients to continue treatment will increase the total exposure and provide more knowledge about OMS721 - Changes to Sections 2, 7.2, 10: Increased stage 2 treatment period for aHUS subjects from 4 weeks to 12 weeks. Rationale: Typically, aHUS is a chronically treated disease. Chronic toxicity evaluation has been completed without significant findings. The increased treatment duration will provide longer treatment that will be provide more benefit to subjects who receive from treatment. - Changes to Sections 2, 13.1: Added detection of AEs that occur at an incidence of at least 7.5% in the separate cohorts. Rationale: Provides level of AE detection for amended sample size - Changes to Sections 5.3.1.3, 10.4.2: Added periodic review by Data Monitoring Committee. Rationale: Provide additional safety monitoring
    20 Jul 2015
    Amendment #8 (Cont'd) - Changes to Sections 2, 5.1.2, 7.1, 8.1, 10.2.1.1, 13.1: Expand TTP patient population by removing refractory criteria and the failure to attain a treatment response criteria related to refractory TTP. Rationale: The inclusion criterion of “refractory TTP” was changed to “TTP” following discussions with several hematologists who informed us that patients meeting the original refractory criterion were extremely rare. Several large centers (e.g., University of Iowa, University or Wisconsin, St. Louis University and University of Pittsburgh told us they have not had any patients meeting the original criterion for several years. Also, no subjects have been screened that meet the refractory criterion. Therefore, it appears that the refractory criterion describes a patient population that is very rare and likely not feasible to study. Hematologists also indicated that, if safe, effective and approved, they envision use of OMS721 as first-line treatment either with or without plasma therapy. Although allowing use of OMS721 as first-line treatment in combination with plasma therapy will complicate determination of efficacy in this study, the hematologists believe that observation of time to response either with or without rituximab can provide adequate proof of principle to justify further placebo-controlled trials in the TTP population. - Changes to Sections 2, 8.1: Remove timeframe criteria of “in the week immediately” for plasma therapy treatments for the Plasma therapy-resistant aHUS patients. Rationale: Subjects with chronic aHUS may have been demonstrated to be plasma therapy resistant in the past. It is not ethical to retreat plasma therapy resistant patients in order to enroll in the study. Therefore, the timing of failed plasma therapy has been deleted. - Changes to Sections 10.1.1.1, 10.1.2.1: Included screening for mycobacterial or significant fungal infection. Rationale: This was added to screen for potential latent infections.
    20 Jul 2015
    Amendment #8 (Cont'd) - Changes to Section 7.2.1, Increased OMS721 upper limit half-life range from 35 to 79. Rationale: Corrected incorrect data point
    20 Apr 2017
    Amendment #9 - Change to Section 2: Investigational Product, Dosage, and Mode of Administration: Added a second formulation of OMS721, ‘Drug Product, OMS721 185 mg/mL. Rationale: To add another formulation of OMS721 for use in the study.
    12 Oct 2018
    Amendment #10 - Change to Section 2: Methodology: Enrollment of aHUS and TTP subjects is closed. Rationale: Stage 1 of the protocol is complete. For Stage 2 and 3 enrollment of aHUS and TTP subjects is closed. Enrollment of HSCT-TMA patients is ongoing. - Change to Section 2: Methodology: Changed the dose to 370 mg IV weekly (from 4.0 mg/kg IV weekly). Rationale: Updated the Stage 2 and 3 dose for HSCT-TMA patients to 370 mg IV weekly. Subjects in the middle of a treatment cycle at the time of implementation of Amendment 10 should continue with their original dose. - Change to Section 2: Investigational Product: As of Amendment 10 the 100 mg/mL Injection Solution formulation is no longer being used. Updated to reflect that Drug Product, OMS721 185 mg/mL will be the formulation used. Rationale: The 100 mg/mL Injection Solution is no longer being used, and all subjects will be dosed with Drug Product OMS721 185 mg/mL moving forward. Subjects in the middle of a treatment cycle at the time of implementation of Amendment 10 should stay on their original dose and formulation. - Change to Section 2: Statistical Methods: Efficacy: The description of primary and secondary endpoint analysis was changed to state that all study endpoint will be summarized descriptively by cohort and visit (if applicable). Rationale: Updating the description of efficacy analysis. - Change to Section 5.2.1: The nonclinical experience section was updated to include the most up to date information. Includes reproductive and development studies. Rationale: Provide updated nonclinical study information. - Change to Section 7.2.1: Updated rationale for selection of doses to reflect the change to 370 mg dose. Included 3 new figures showing that there is no correlation between body weight parameters and clearance of OMS721. Rationale: Provided rationale for change of dose to 370 mg.
    08 May 2020
    Amendment #11: - Change to Sections 2, 6.1: Objectives: Revised the co-primary objective from “evaluate the clinical activity of multiple-dose administration of OMS721 in subjects with TMA” to “Evaluate the efficacy of OMS721 in patients with HSCT-TMA by response defined as improvement in TMA laboratory markers of platelet count and LDH, and improvement in clinical status.” Rationale: To provide more detail on the definition of clinical activity and response in HSCT-TMA patients - Change to Sections 2, 7.1, 19.4: Added that “for patients with HSCT-TMA enrolled under Amendment 10 or earlier versions of this protocol, additional data will be collected. These data will include supplemental data on patient demographics and baseline conditions, donor characteristics, the transplant procedure, concomitant medications, TMA-related laboratory measures, transfusions, transplant complications, and outcomes. These data will be derived from medical records from the time of transplant conditioning through the last available patient contact with the site, or up to 2 years (104 weeks) following the first dose of OMS721, whichever comes first.” Also added that “as of Amendment 11, enrollment in the study has been completed, and the additional data will be collected until a predetermined data cutoff date for those patients who have not reached 2 years after first OMS721 dose” Rationale: These data were requested by regulatory authorities because patients who have undergone HSCT typically have complicated post-transplant courses, and these additional data will provide the needed information to draft patient narratives, including the full patient profile, and allow for better understanding of OMS721 response and outcomes.
    08 May 2020
    Amendment #11 (Cont'd) - Change to Sections 2, 13.2.10: Added “The coronavirus associated lockdown situation in various countries has created uncertainty in the ability to collect all follow-up data and resolve all queries on a few patients enrolled in the study. When adequate data on the primary and secondary endpoints is available, the database will be locked for interim analyses and creation of an interim CSR to enable regulatory submission for drug approval. Efforts will continue to collect additional follow-up data and resolve any outstanding queries.” Rationale: An interim database lock is planned to enable regulatory submission of the data. Due to the coronavirus situation in many countries, there may be some queries that have not been resolved by the time of the interim database lock, however efforts will continue to resolve those before final database lock. - Change to Sections 2, 7.1: Revised the number of patients planned from 89 to approximately 60. Rationale: "To reflect that enrollment is closed, with the planned total sample size for HSCT-TMA patients of 28"
    08 May 2020
    Amendment #11 (Cont'd) - Change to Sections 2, 7.3.1: Revised the primary endpoint from “clinical activity assessed by platelet count” to: “For HSCT-TMA patients, response to OMS721 treatment. A responder is defined as a patient with HSCT-TMA who demonstrates improvement in laboratory TMA markers (platelet count and LDH) and clinical benefit (either improvement in organ function or reduction in transfusion burden). The specific criteria are defined as follows: Improvement in laboratory TMA markers: * Platelet count: ** For patients with baseline platelet count = 20,000/µL: tripling of baseline platelet count AND post-baseline platelet count > 30,000/µL AND no platelet transfusions 2 days before and on the day of the platelet count collection. ** For patients with baseline platelet count > 20,000/µL: increase in platelet count = 50% AND post-baseline platelet count > 75,000/µL AND no platelet transfusions 2 days before and on the day of the platelet count collection. * LDH: is defined as LDH < 1.5 times ULN.
    08 May 2020
    Amendment #11 (Cont'd) - Improvement in clinical status: • Improvement in organ function as evidenced by any of the following criteria: o Improvement in renal function as evidenced by any of the following: 1) a reduction of creatinine > 40%; 2) creatinine < ULN and reduction of creatinine > 20%; or 3) discontinuation of renal replacement therapy (RRT). o Improvement in pulmonary function as evidenced by either of the following criteria: 1) extubation and discontinuation of ventilator support; or 2) discontinuation of noninvasive mechanical ventilation (continuous positive pressure ventilation). o Improvement in neurological function as evidenced by either of the following criteria: 1) improvement in reversible neurological conditions (e.g., cessation of seizures); or 2) stabilization of irreversible neurological conditions (e.g., stability of neurological deficits following stroke without further deterioration or subsequent strokes). o Improvement in gastrointestinal function (gastrointestinal HSCT-TMA requires diagnosis by tissue biopsy) as measured by improvement in the gastrointestinal measures in the Mount Sinai Acute Graft Versus Host Disease (GVHD) International Consortium (MAGIC) criteria OR • Freedom from transfusion (no transfusions for at least 4 weeks from the last transfusion except for patients who died within 4 weeks of the last transfusion; only evaluated in patients who received transfusions within the 2 weeks prior to or on the first OMS721 dose date) Rationale: To provide more detail on the definition of clinical activity and response in HSCT-TMA patients.
    08 May 2020
    Amendment #11 (Cont'd) - Revised and added to the secondary endpoints to include: • Duration of response, defined as the number of days from the first response date to the first relapse date • 100-day survival, from the date of TMA diagnosis • Overall survival, from the date of TMA diagnosis • Freedom from platelet transfusion defined as no platelet transfusions for at least 4 weeks following the last platelet transfusion except for patients who died within 4 weeks of the last platelet transfusion (only evaluated in patients who had platelet transfusions in the 2 weeks prior to or on the first OMS721 dose date) • Freedom from RBC transfusion defined as no RBC transfusions for at least 4 weeks following the last RBC transfusion except for patients who died within 4 weeks of the last RBC transfusion (only evaluated in patients who had RBC transfusions in the 2 weeks prior to or on the first OMS721 dose date) • Change from baseline in platelet count (post baseline platelet counts without platelet transfusions 2 days before and on the day of the platelet count collection will be used) over time using central laboratory values • Change from baseline in LDH over time using central laboratory values • Change from baseline in haptoglobin over time using central laboratory values • Change from baseline in Hgb (post baseline Hgb without RBC and whole blood transfusions 6 days before and on the day of the Hgb collection will be used) over time using central laboratory values • Change from baseline in creatinine over time using central laboratory values • The PK of multiple-dose administration of OMS721 (this will be assessed in patients with HSCT-TMA as well as patients with aHUS and TTP) • The PD of multiple-dose administration of OMS721(this will be assessed in patients with HSCT-TMA as well as patients with aHUS and TTP)
    08 May 2020
    Amendment #11 (Cont'd) - Revised and added to the secondary endpoints to include: • The immunogenicity of multiple-dose administration of OMS721 (this will be assessed in patients with HSCT-TMA as well as patients with aHUS and TTP) • Rationale: To provide for the collection of data for further evaluation of the benefit and risk of OMS721 for the treatment of HSCT-TMA - Changes to Section 6.2: Updated the Secondary Study Objectives to match the revised Secondary Endpoints. Rationale: To provide consistency throughout the protocol amendment - Changes to Section 6.3: Added the exploratory objective “Describe the effect of OMS721 on TMA laboratory markers in patients with aHUS and TTP”. Rationale: This is a primary endpoint in HSCT-TMA patients but will also be examined as an exploratory objective for aHUS and TTP patients
    08 May 2020
    Amendment #11 (Cont'd) - Changes to Section 7.3.3: Revised the exploratory endpoints from MBL and MASP-2 concentration to: • Assess the effect of baseline circulating MBL levels on PK and PD measures in patients with HSCT-TMA, aHUS, and TTP • Assess the effect of baseline circulating MASP-2 levels on PK and PD measures in patients with HSCT-TMA, aHUS, and TTP • Describe the effect of OMS721 on TMA laboratory markers in patients with aHUS and TTP • Rationale: To expand on and provide more detail on the exploratory endpoints
