About this study

Official title: A Phase 1 Double-blind, Randomized, Placebo-Controlled, Staggered, Single and Multiple Ascending Dose, Multicenter Study Evaluating the Safety, Tolerability, Pharmacokinetics and Efficacy of GS-5745 in Subjects With Moderate to Severe Ulcerative Colitis

The primary objectives of this study are as follows:

  • To assess the safety and tolerability of escalating single and multiple doses of GS-5745 (andecaliximab) in participants with moderate to severe ulcerative colitis (UC) as assessed by adverse events (AEs) and laboratory abnormalities
  • To assess the pharmacokinetics (PK) of GS-5745 (andecaliximab) in participants with moderate to severe UC.
Read the detailed description

The study will test the safety of the drug. Participants will be given different concentrations of the drug in Cohorts, starting from a lower dose to a higher dose.

Single-Dose Treatment:

A thorough assessment of safety and tolerability will be performed before escalating to the next higher dose. For example, the first 2 participants will be dosed in a staggered fashion 24 hours apart. Provided that there are no significant safety signals up to 24 hours post-dose for the first 2 participants, the remaining 4 participants will be dosed. A thorough assessment of safety and tolerability (through Day 14 post-dose) will be performed by the safety review committee before escalating to the next higher dose. Participants enrolled in a SAD cohort will be eligible to participate in a MAD or adaptive MAD cohort if eligibility criteria are met.

Multiple-Dose Treatment:

This design follows the same set-up as the Single-Dose Treatment. Dosing will not commence in the first MAD cohort until safety data from the second dose level SAD cohort has been reviewed through Day 15. Successive MAD cohorts will only be dosed after safety data from the previous, lower dose MAD cohort through Day 43 and the next higher dose SAD cohort through Day 15, have been reviewed by the safety review committee. An additional Adaptive MAD cohort will explore a subcutaneous dosing of andecaliximab 150 mg prefilled syringe once a week for 5 weeks.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants Who Experienced Any Treatment-Emergent Adverse Events (TEAEs) (SAD/MAD)

    TEAEs are any AEs with an onset date of on or after the study drug start date and no later than 30 days after permanent discontinuation of study drug or any AEs leading to premature discontinuation of study drug.

    Measured: SAD Cohorts: First dose date (Day 1) plus 30 days, MAD/Adaptive MAD Cohort: First dose date up to last dose date (Maximum: Day 29) plus 30 days

  2. Pharmacokinetic (PK) Parameter: Cmax (SAD)

    Cmax is defined as the maximum concentration of drug.

    Measured: Predose and 1, 2, and 6 hours postdose on Day 1; Days 2, 3, 8, 15, 29, and 43

  3. PK Parameter: Cmax (MAD)

    Cmax is defined as the maximum concentration of drug over the dosing interval. Data for Day 1 was based on the data collected from Day 1 through Day 8. Data for Day 29 was based on the data collected from Day 29 through Day 36.

    Measured: MAD Cohorts: Predose and 1, 2, and 6 hours postdose on Days 1 and 29, Predose on Days 8 and 36; Adaptive MAD Cohort: Predose and 6 hours postdose on Days 1, and 29, Predose on Days 8 and 36

  4. PK Parameter: Ctau (MAD)

    Ctau is defined as the observed drug concentration at the end of the dosing interval.

    Measured: MAD Cohorts: Predose and 1, 2, and 6 hours postdose on Day 29; Predose on Day 36; Adaptive MAD Cohort: Predose and 6 hours postdose on Day 29; Predose on Day 36

  5. PK Parameter: AUCinf (SAD)

    AUCinf is defined as the area under the plasma concentration versus time curve extrapolated to infinite time.

    Measured: Predose and 1, 2, and 6 hours postdose on Day 1; Days 2, 3, 8, 15, 29, and 43

  6. PK Parameter: AUCtau (MAD)

    AUCtau is defined as the area under the plasma concentration versus time curve over the dosing interval. Data for Day 1 was based on the data collected from Day 1 through Day 8. Data for Day 29 was based on the data collected from Day 29 through Day 36.

    Measured: MAD Cohorts: Predose and 1, 2, and 6 hours postdose on Days 1 and 29; Predose on Days 8 and 36; Adaptive MAD Cohort: Predose and 6 hours postdose on Days 1, and 29; Predose on Days 8 and 36

  7. PK Parameter: AUClast (SAD)

    AUClast is defined as the area under the plasma concentration versus time curve from time zero to the last observable concentration.

    Measured: Predose and 1, 2, and 6 hours postdose on Day 1; Days 2, 3, 8, 15, 29, and 43

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Andecaliximab in people with Ulcerative Colitis, run by Gilead Sciences at 16 sites in 7 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Feb 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 16 sites in United States, Hungary, Canada, Netherlands, Belgium and 2 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 1 Feb 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Participants Who Experienced Any Treatment-Emergent Adverse Events (TEAEs) (SAD/MAD) (time frame: SAD Cohorts: First dose date (Day 1) plus 30 days, MAD/Adaptive MAD Cohort: First dose date up to last dose date (Maximum: Day 29) plus 30 days). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01831427, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Feb 2021.
