Filgotinib in Long-Term Extension Study of Adults With Ulcerative Colitis


  • Study type

  • Study phase

  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

Inclusion Criteria:

Subjects must meet all of the following inclusion criteria to be eligible for participation in this study:

  • Must have the ability to understand and sign a written ICF, which must be obtained prior to initiation of study procedures associated with this trial
  • Must have met all eligibility criteria from a Gilead-sponsored UC parent protocol.
  • Must have completed all required procedures or met protocol specified efficacy discontinuation criteria in a prior Gilead-sponsored filgotinib treatment study for UC.
  • Females of childbearing potential must have a negative pregnancy test at Day 1 and must agree to continued monthly pregnancy testing during use of filgotinib treatment.
  • Male subjects and female subjects of childbearing potential who engage in heterosexual intercourse must agree to use protocol specified method(s) of contraception as described in Appendix 6, for the duration described.
  • Willingness to refrain from live or attenuated vaccines during the study and for 12 weeks after last dose of study drug.

Exclusion Criteria:

Subjects who meet any of the following exclusion criteria are not to be enrolled in this study:

  • Subjects who are discontinued from a parent study for reasons other than disease worsening, or lack of response or remission; eg, subjects who discontinue for safety or tolerability issues are not eligible for the present study.
  • Known hypersensitivity to the study drug.
  • Any chronic medical condition (including, but not limited to, cardiac or pulmonary disease, alcohol or drug abuse) that, in the opinion of the Investigator or Sponsor, would make the subject unsuitable for the study or would prevent compliance with the study protocol.
  • Females who may wish to become pregnant and/or plan to undergo egg donation or egg harvesting for the purpose of current or future fertilization during the course of the study and for at least 35 days of the last dose of the study drug.
  • Male subjects unwilling to refrain from sperm donation for at least 90 days after the last dose of study drug.
  • Males or females of reproductive potential who are unwilling to abide by protocol-specified contraceptive methods as defined in Appendix 6.
  • Use of prohibited concomitant medications as outlined in Section 5.4.2.
