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   43841   clinical trials with a EudraCT protocol, of which   7281   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.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To evaluate the efficacy and safety of tofacitinib in subjects in stable remission on 10 mg BID who decrease the dose to and remain on 5 mg BID (“fixed 5 mg BID dose group”) compared to subjects remaining on 10 mg BID. Primary comparisons will be based on data from the first 6 months.
    E.2.2Secondary objectives of the trial
    • To evaluate the efficacy and safety of tofacitinib in subjects in stable remission on 10 mg BID who decrease the dose to 5 mg BID with option for dose escalation for flare (“flexible dosing regimen”) compared to subjects staying on 10 mg BID for 18 months.
    • To evaluate the efficacy and safety of the subset of subjects in stable remission on 10 mg BID who have flare after dose decrease to tofacitinib 5 mg BID and are re-treated with 10 mg BID.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Subjects currently enrolled in Study A3921139 who were initially assigned to tofacitinib 10 mg BID at baseline of A3921139.
    2. Subjects who are in stable remission on tofacitinib 10 mg BID for the 6 month period in Study A3921139 up to and including baseline of Study A3921288, defined as meeting all of the following criteria:
    a. A partial Mayo score ≤2, with no individual subscore >1 and a rectal bleeding subscore of 0 at each study visit during the 6 month period in Study A3921139 prior to and including baseline of Study A3921288;
    b. AND at least one assessment of remission based on Mayo score;
    • If an endoscopy was not completed ≤6 months prior to baseline of Study A3921288, then an endoscopy performed in study A3921139 with an endoscopic subscore of 0 or 1, will be required prior to randomization into Study A3921288.
    • All available assessments based on Mayo score during this period must show remission.
    c. AND subjects must not be receiving any corticosteroid therapy for their UC for at least 4-weeks prior to baseline.
    3. Female subjects of childbearing potential must agree to use a highly effective method of contraception throughout the study and for at least 28 days after the last dose of assigned treatment. Subjects in Canada who are women of childbearing potential and sexually active must use two contraceptive methods at the same time: one highly effective contraceptive method and one additional effective contraceptive method (see Protocol Section 4.4.4).
    4. Female subjects of childbearing potential must have a negative urine pregnancy test prior to randomization.
    5. Subjects who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, bowel movement diary calls, and other study procedures.
    6. Evidence of a personally signed and dated informed consent document indicating that the subject (or a legally acceptable representative) has been informed of all pertinent aspects of the study.
    E.4Principal exclusion criteria
    1. Subjects who were initially assigned to tofacitinib 5 mg BID at baseline of Study A3921139.
    2. Subjects who were initially assigned to tofacitinib 10 mg BID at baseline of Study A3921139 whose tofacitinib dose was reduced to 5 mg BID due to safety or efficacy.
    3. Presence of indeterminate colitis, microscopic colitis, ischemic colitis, infectious colitis, or clinical findings suggestive of Crohn’s disease.
    4. Subjects who in the opinion of the investigator, are likely to require surgery for UC during the study period.
    5. Subjects who are expected to receive any prohibited medications, including medications that are either moderate to potent CYP3A inducers or inhibitors, during the study period as specified in the protocol (see Protocol Appendix 3).
    6. Subjects who are expected to receive live or attenuated virus vaccination during study period and for 6 weeks after last dose of investigational product.
    7. Women who are pregnant or breastfeeding, or planning to become pregnant during the study period.
    8. Subjects with evidence of colonic malignancy or any dysplasia (eg, “flat dysplasia”; polyp) identified on endoscopic exam during Study A3921139. Subjects with completely resected adenomatous polyp(s) outside of (proximal to) the extent of colitis may be eligible upon consultation with the sponsor. Note, pathology report must be reviewed prior to subject enrolment.
    9. Other acute or chronic medical or psychiatric condition including recent (within the past year) or active suicidal ideation or behavior or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the subject inappropriate for entry into this study.
    10. Investigator site staff members directly involved in the conduct of the study and their family members, site staff members otherwise supervised by the investigator, or subjects who are Pfizer employees, including their family members, directly involved in the conduct of the study.
    11. Subjects who, in the opinion of the investigator or Pfizer, will be uncooperative or unable to comply with study procedures.
    12. Participation in other studies involving investigational drug(s) during study participation.
    E.5 End points
    E.5.1Primary end point(s)
    Remission based on modified Mayo score at Month 6.
    E.5.1.1Timepoint(s) of evaluation of this end point
    The primary analysis will be performed at Month 6 based on the FAS for the estimation of
    treatment difference between two dose groups: Tofacitinib 10 mg BID and Tofacitinib 5 mg BID.
    The stratified estimation of the treatment difference between tofacitinib 10 mg BID and 5 mg BID in the proportion of subjects with remission at Month 6 will be presented along with its 95% confidence interval (CI). The Cochran-Mantel-Haenszel (CMH) weight method will be used for the stratified estimation of the treatment difference. The stratified CI will be constructed using the NewCombe method. Subjects with dose escalation prior to Month 6 or with missing values at Month 6 will be treated as non-responders at Month 6.
    E.5.2Secondary end point(s)
    Secondary Efficacy Endpoints:
    • Time to loss of remission based on modified Mayo score.
    • Remission based on the following: modified Mayo score, modified partial Mayo score, total Mayo score, and partial Mayo score.
    • Change from baseline (of Study A3921288) in the following: modified Mayo score, modified partial Mayo score, total Mayo score, and partial Mayo score.
    • Mucosal healing.
    • Clinical response based on Mayo score.
    • Change from baseline in fecal calprotectin and hs-CRP levels.
    For additional safety endpoints please refer to the study protocol.
    E.5.2.1Timepoint(s) of evaluation of this end point
    For efficacy endpoints based on Mayo score, the change from baseline will be analyzed using an analysis of covariance model with treatment group, the endoscopic subscore at baseline (0 versus 1) as factors and baseline score as a covariate. For other endpoints, the change from baseline will be analyzed using linear mixed-effects model with baseline value, treatment group, the endoscopic subscore at baseline (0 versus 1), visit, and treatment group by visit interaction all as fixed effects, and an unstructured covariance matrix for within-subject measurements over visits. The adjusted estimations and associated 95% CI for the overall difference between the two groups will be computed.
