About this study

Official title: A Randomized, Placebo-controlled, Parallel-group, Investigator- and Participant-blinded Phase 2a Study to Investigate the Efficacy, Safety, and Tolerability of DFV890 and MAS825 for Inflammatory Marker Reduction in an Adult Population With Coronary Heart Disease and Clonal Hematopoiesis of Indeterminate Potential (CHIP)

This Phase 2a clinical trial evaluated the effectiveness, safety, and tolerability of increasing dose strengths of an oral daily medication, DFV890, administered for 12 weeks, or a single s.c. dose of MAS825, to reduce key markers of inflammation related to CVD risk, such as IL-6 and IL-18, in approximately 28 people with known coronary heart disease and TET2 or DNMT3A CHIP (variant allele frequency [VAF] ≥2%).

Read the detailed description

This was a multi-center, randomized, placebo-controlled, participant- and investigator-blinded study.

The study consisted of a screening period up to 30 days; a treatment period of approximately 12 weeks with an end of treatment (EOT) visit on Day 85, which is one day after the last dose of DFV890 or placebo; a follow-up period of approximately 1 week; and a standard safety follow-up call approximately 30 days following the last dose. The overall study duration is approximately 21 weeks.

Participants were randomized to one of five treatment sequences. Based on the treatment sequence assignments, participants started on either a combination of MAS825 and placebo, DFV890 and placebo, or placebo and placebo on Day 1, and then, within each DFV890 treatment sequence, participants received up-titrating doses of DFV890 or placebo at the corresponding study visits. None of the treatment sequences included a combination of both active DFV890 and active MAS825.

What is being measured

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

  1. Ratio to Baseline Serum Levels of IL-6 for DFV890 Based on an Emax Model

    Serum levels of IL-6 at 3 weeks after the start of a dosing period for DFV890. The circulating serum levels of the cytokine IL-6 were measured by a validated enzyme-linked immunosorbent assay (ELISA) assay at a qualified vendor.

    The Emax model selected for IL-6 analysis was a model with 2 covariates (IL-6 baseline and bodyweight) and 1 random effect.

    Measured: Baseline (before first dose of study drug), 3 weeks after the start of a dosing period for DFV890 (between Day 22 and Day 85, depending on treatment sequence assignment)

  2. Ratio to Baseline Serum Levels of IL-18 for DFV890 Based on an Emax Model

    Serum levels of IL-18 at 3 weeks after the start of a dosing period for DFV890. The circulating serum levels of the cytokine IL-18 were measured by a validated enzyme-linked immunosorbent assay (ELISA) assay at a qualified vendor.

    The Emax model selected for IL-18 was a model with one covariate (IL-18 baseline) and 1 random effect.

    Measured: Baseline (before first dose of study drug), 3 weeks after the start of a dosing period for DFV890 (between Day 22 and Day 85, depending on treatment sequence assignment)

  3. Ratio to Baseline Serum Levels of IL-6 for MAS825 Based on a Traditional Linear Regression Model

    Serum level of IL-6 at Week 3 for MAS825. The circulating serum levels of the cytokine IL-6 was measured by a validated enzyme-linked immunosorbent assay (ELISA) assay at a qualified vendor.

    Data was analyzed with a a traditional linear regression model including treatment as a fixed categorical effect, a random intercept effect for participant, and the baseline value of the biomarker and baseline body weight as covariates.

    Measured: Baseline (before first dose of study drug), 3 weeks after a single MAS825 dose on Day 1.

Secondary outcomes (2)
  1. Trough Plasma Concentration (Ctrough) of DFV890 at Steady-state

    Ctrough is the observed plasma concentration that is just prior to the beginning of, or at the end of a dosing interval.

    Measured: After the last dose of each 3-week dosing period: Day 22 pre-dose, Day 43 pre-dose, Day 64 pre-dose, or Day 85, depending on treatment sequence assignment

  2. MAS825 Serum Concentrations

    MAS825 serum concentrations were determined using a validated target-based sandwich ELISA.

    Measured: Day 22, Day 43, Day 64 and Day 85

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing MAS825 and DFV890 in people with Coronary Heart Disease and Clonal Hematopoiesis of Indeterminate Potential (CHIP), run by Novartis Pharmaceuticals at 6 sites in 3 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 5 inclusion and 8 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 9 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Germany, United States, Canada. 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 27 Mar 2026). 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?

Ratio to Baseline Serum Levels of IL-6 for DFV890 Based on an Emax Model (time frame: Baseline (before first dose of study drug), 3 weeks after the start of a dosing period for DFV890 (between Day 22 and Day 85, depending on treatment sequence assignment)). The study lists 3 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 NCT06097663, which also lists 2 linked publications.

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 9 Apr 2026.
