Trial summary

IMO 8400 is a second-generation oligonucleotide antagonist of endosomal Toll-like receptors (TLR) 7, TLR8 and TLR9. These TLR react to complexes of exogenous nucleic acids (as might be encountered during infection) and endogenous nucleic acids (as might be released during tissue damage during autoimmune disease).

About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled, 12-week Dose-Ranging Trial of IMO-8400 in Patients With Moderate to Sever Plaque Psoriasis

IMO 8400 is a second-generation oligonucleotide antagonist of endosomal Toll-like receptors (TLR) 7, TLR8 and TLR9. These TLR react to complexes of exogenous nucleic acids (as might be encountered during infection) and endogenous nucleic acids (as might be released during tissue damage during autoimmune disease). In vitro and in multiple animal models of autoimmune disease, IMO-8400 blocks immune activation mediated through TLR7, 8 and 9. In Phase 1 studies (Protocol 8400-001) IMO 8400 has been administered to healthy adults by SC injection at single-doses and multiple-doses (4 weeks) up to 0.6 mg/kg. All treatments were well-tolerated, with mild injection site reactions and no pattern of systemic reactions or laboratory changes.

The current study represents the first clinical trial of IMO-8400 in patients with active autoimmune disease. Moderate to severe plaque psoriasis was chosen for this 12-week proof of activity trial based on a prior 4-week study using a first generation TLR7 and 9 antagonist which demonstrated clinical improvement in this patient population.

Read the detailed description

Eligible subjects will be enrolled and randomized to receive one of the four treatments (three dose levels of IMO-8400 or Saline Placebo). Treatments will be administered once weekly by subcutaneous injections. Subjects will received treatment for 12 weeks and then be followed for an additional 6 weeks to assess the durability of the response.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing IMO-8400 Regimen 1, IMO-8400 Regimen 2 and IMO-8400 Regimen 3 in people with Plaque Psoriasis, run by Idera Pharmaceuticals, Inc. at 1 site in Netherlands.

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 6 inclusion and 24 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 7 Apr 2022. 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 Netherlands. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 2 Aug 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?

Safety and Tolerability of IMO-8400 Compared With Placebo (time frame: 19 weeks (12 weeks on treatment + 7 week follow up)). 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 NCT01899729, 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 7 Apr 2022.
