Trial Summary

What is the purpose of this trial?

This trial is testing injections of a drug called tozorakimab in adults with COPD who have frequent flare-ups. These patients are already on other inhaled treatments but still experience significant symptoms. The drug aims to reduce lung inflammation and prevent these flare-ups.

Will I have to stop taking my current medications?

The trial does not specify that you need to stop taking your current medications. However, you must be on a stable dose of inhaled therapy (like ICS/LABA/LAMA) for at least 3 months before joining the study.

What data supports the effectiveness of the drug Tozorakimab for COPD?

Research on similar treatments, like mepolizumab, shows that targeting specific inflammatory pathways can reduce exacerbation rates in COPD patients with high eosinophil levels. This suggests that Tozorakimab, which may work in a similar way, could potentially be effective for certain COPD patients.12345

What makes the drug Tozorakimab unique for treating COPD?

Tozorakimab (MEDI-3506) is unique for treating COPD because it targets the interleukin-6 (IL-6) pathway, which is involved in inflammation, a key factor in COPD. This mechanism is different from standard COPD treatments that typically focus on bronchodilation or reducing mucus production.678910

Eligibility Criteria

Adults over 40 with COPD, a history of frequent flare-ups, and on stable inhaled medication can join this trial. They must have a significant smoking history and symptoms like coughing and phlegm. People with other serious lung diseases, recent severe infections or exacerbations, unstable health conditions, or past use of the study drug are excluded.

Inclusion Criteria

I've had at least 2 moderate or 1 severe COPD flare-ups in the last year.
CAT total score ≥10, with each of the phlegm (sputum) and cough items with a score ≥ 2
I am 40 years or older and can sign a consent form.

Findings from Research

Monoclonal antibody (mAB) therapies have a moderate effect on reducing the risk of exacerbations in chronic obstructive pulmonary disease (COPD), but they do not significantly improve lung function (FEV1) or quality of life (SGRQ).
In eosinophilic COPD patients, the IL-5 antagonist mepolizumab was found to reduce exacerbation risk, while benralizumab showed effectiveness in improving both lung function and quality of life, highlighting the potential of targeting IL-5 pathways in specific patient populations.

In a meta-analysis of 1136 patients from the METREX and METREO trials, mepolizumab significantly reduced the annual rate of moderate to severe exacerbations in COPD patients with elevated blood eosinophil counts by 18% compared to placebo.
The study found that higher blood eosinophil counts were associated with greater efficacy of mepolizumab, suggesting that patients with eosinophil counts of ≥150 cells/µL at screening or ≥300 cells/µL in the prior year are more likely to benefit from this treatment.

In a study involving 66 COPD patients and 15 healthy controls, it was found that COPD serum significantly increased pro-inflammatory markers like CCL5 and TNF-α while decreasing the anti-inflammatory marker IL-10, indicating a strong pro-inflammatory effect in COPD.
The p38 inhibitor SB203580 was able to suppress inflammation by reducing CCL5 and TNF-α levels and increasing IL-10 production, but its effectiveness was limited in COPD patients, suggesting that there are other inflammatory mechanisms at play that do not involve p38 signaling.
