ISIS 2302-CS22, A 6-Week, Active-Controlled Clinical Study to Evaluate the Effectiveness of Alicaforsen (ISIS 2302) in Patients With Mild to Moderate Active Ulcerative Colitis

December 1, 2022 updated by: Ionis Pharmaceuticals, Inc.

ISIS 2302-CS22, Phase II, Double-Blinded, Active-Controlled Study of Alicaforsen (ISIS 2302) Enema, an Antisense Inhibitor of ICAM-1, for the Treatment of Patients With Mild to Moderate Active Ulcerative Colitis (Left-Sided Colitis or Pancolitis With Left Sided Disease Flare)

This is a multi-center trial to test the safety, efficacy and tolerability of alicaforsen (ISIS 2302), a new type of drug called an antisense drug, in patients with mild to moderate active Ulcerative Colitis (UC). Alicaforsen is designed to reduce the production of a specific protein, called ICAM-1, a substance that plays a significant role in the increase of inflammation and is likely to be involved in inflammatory bowel diseases such as ulcerative colitis. The ISIS 2302-CS22 study will examine the effects of one of two dosages of alicaforsen delivered by enema over a six-week period as compared to an active control, mesalamine enema (The probability of receiving the alicaforsen formulation is 2:1). The primary objective of this study is to evaluate the percentage reduction in DAI at Week 6.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

  • Baseline DAI score of 4-10 including abnormal endoscopic score

  • On at least one or more of the following treatments for ulcerative colitis prior to baseline visit:

    1. Stable background oral mesalamine therapy for greater than or equal to 30 days, and/or
    2. Stable background mercaptopurine for greater than or equal to 60 days prior to baseline, and/or
    3. Stable azathiprine therapy for greater than or equal to 60 days prior to baseline
  • Written informed consent prior to performing screening evaluations.

Exclusion criteria

Patients who meet any of the following criteria at screening are not eligible for enrollment:

  • Bowel stricture, toxic megacolon, colonic dysplasia, adenoma or carcinoma
  • Uncontrolled hematologic, renal, hepatic, metabolic, psychiatric, CNS, pulmonary or cardiovascular disease, or sufficient level of disease that could interfere with the patient's ability to comply with protocol participation

  • Non-steroidal anti-inflammatory agents (NSAIDs), including cyclooxygenase-2 (COX-2) inhibitors, within 14 days of baseline visit
  • Methotrexate, cyclosporin or thalidomide within 90 days of baseline visit
  • Any active infection currently requiring treatment
  • Malignancy within 5 years except for squamous cell or basal cell cancers of the skin
  • Current infectious, ischemic, or immunological disease with gastrointestinal involvement
  • ISIS 2302 treatment within 12 months of baseline visit
  • History of allergy to mesalamine
  • Treatment with an investigational or off-label drug within 90 days of screening or currently in long-term follow up for another investigational treatment protocol

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
November 20, 2002

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
