About this study
Official title: A Phase 1, Multi-center, Randomized, Double-Blind, Placebo-controlled, Dose-escalation Safety Assessment Study of Combination Treatment With IMO-2125 and Ribavirin in Naïve Hepatitis C-infected, Genotype 1 Patients
Phase 1, randomized, double-blind, placebo-controlled, dose-escalation study with 3 dose levels of IMO-2125 in combination with standard weight based ribavirin (investigational treatment arm) or placebo in combination with ribavirin (RBV). Each cohort of 15 patients will be randomized 4:1 to receive the investigational treatment arm (12 patients) or placebo and RBV arm (3 patients).
Read the detailed description
This is a phase 1, randomized, double-blind, placebo-controlled, dose-escalation study with 3 dose levels of IMO-2125 in combination with standard ribavirin or placebo plus ribavirin. Each cohort will be randomized 4:1 to receive the investigational treatment arm or placebo and ribavirin. Three varying dose levels of IMO-2125 will be included. In both arms, ribavirin will be dosed based on patient weight.
Approximately 50 patients will be enrolled in France and Russia. Patients will provide informed consent prior to any screening procedures being performed. Screening will occur within 21 days prior to randomization. Enrolled patients who qualify and proceed successfully through the screening period will be randomized to receive 4 weeks of either the investigational treatment arm (IMO-2125 and ribavirin) or placebo and ribavirin, with a 4 week follow-up period.
Patients who are randomized to the investigational treatment arm will receive one of 3 dose levels of IMO 2125 SC once weekly; each patient will receive the same dose throughout the 4 weeks of treatment. In addition to IMO-2125 treatment they will also receive daily ribavirin, which will be given based on the patients weight and will be taken twice daily for a total of 4 weeks.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
IMO-2125Drug
IMO 2125 is a synthetic DNA-based agonist of Toll-like receptor 9, which is expressed in humans in plasmacytoid dendritic cells and B cells of the immune system.
SalineDrug
Subcutaneous injection once per week for four weeks
| Study group | Role | What they receive |
|---|---|---|
| Saline | Placebo comparator | If randomized to placebo the patient will receive a subcutaneous injection once per week for 4 weeks Receives: Drug: Saline |
| IMO-2125 | Experimental | If randomized to receive the experimental treatment, IMO-2125, the patient will receive a subcutaneous injection once per week for 4 weeks Receives: Drug: IMO-2125 |

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing IMO-2125 and Saline in people with Hepatitis C, Treatment Naïve, Genotype 1 Patients, run by Idera Pharmaceuticals, Inc. at 1 site in France.
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 2 inclusion and 5 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 15 Feb 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. 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 15 Feb 2019). 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?
At Least 1 TEAE (time frame: From first dose of study treatment to day 59 (end of study)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 15 Feb 2019; AzTrials last refreshed its copy on 7 Nov 2026.
