What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests tozorakimab, a medication administered via an injection under the skin, to determine its effectiveness for people with COPD, a lung disease that causes breathing difficulties and frequent flare-ups. Researchers are testing two different doses of tozorakimab, along with a placebo, to compare their effectiveness. The trial aims to assess the treatment's efficacy and safety for individuals with COPD. Ideal candidates for this trial have had COPD for at least a year, frequently experience flare-ups, and regularly use inhalers. As a Phase 3 trial, this study is the final step before FDA approval, offering participants the opportunity to contribute to a potentially groundbreaking treatment for COPD.

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.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that tozorakimab was well tolerated in earlier studies. Previous patients did not experience major safety concerns with this treatment. In four different studies, tozorakimab did not cause any significant safety issues, suggesting that the treatment is generally safe for humans. However, this trial is in an advanced phase, indicating that much safety information has already been collected. This phase typically focuses on confirming safety and effectiveness in larger groups of people. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about Tozorakimab for COPD because it offers a new approach by targeting the inflammatory pathways involved in the disease. Most current treatments for COPD, like bronchodilators and corticosteroids, focus on opening the airways or reducing inflammation broadly, but Tozorakimab aims to specifically modulate the immune response by inhibiting certain cytokines. This targeted action could potentially lead to better control of symptoms and fewer side effects. Additionally, Tozorakimab is administered subcutaneously, which might provide more consistent medication levels and improved patient adherence compared to inhaled therapies.

What evidence suggests that this trial's treatments could be effective for COPD?

Research has shown that tozorakimab, a monoclonal antibody, may help treat COPD (Chronic Obstructive Pulmonary Disease). This trial will test different doses of tozorakimab, with some participants receiving Dose 1, others receiving Dose 2, and a separate group receiving a placebo. Studies have found that tozorakimab can lower inflammation, a major cause of COPD flare-ups. In earlier research, patients who received tozorakimab experienced fewer COPD flare-ups compared to those who received a placebo. This treatment works by blocking IL-33, a protein involved in the immune system, which helps reduce lung inflammation. These findings suggest that tozorakimab could effectively manage symptoms and reduce the frequency of COPD flare-ups. ^{1 2 3 4 6}

Are You a Good Fit for This Trial?

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

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.

Exclusion Criteria

I am currently suspected of or confirmed to have COVID-19.

I have active liver disease or jaundice.

I currently have active tuberculosis (TB).

Published Research Related to This Trial

Tocilizumab (TCZ) is an effective treatment for various inflammatory conditions, including rheumatoid arthritis and giant cell arteritis, with strong evidence supporting its long-term safety and efficacy from both clinical trials and real-world studies.

Recent studies have shown that subcutaneous TCZ can lead to significant improvements in patients with systemic sclerosis, indicating its potential for broader applications in other immunological diseases.

In a phase IIIb trial involving 288 patients with moderate-to-severe rheumatoid arthritis (RA), weekly subcutaneous tocilizumab (TCZ-SC) significantly reduced disease activity as measured by the Clinical Disease Activity Index (CDAI) within just 2 weeks, with sustained improvements observed up to 52 weeks.

TCZ-SC demonstrated low immunogenicity and no unexpected toxicities, making it a safe option for patients, and the study suggests that home administration of the treatment is feasible after a median of just 2 doses.

Mepolizumab has been shown to significantly reduce the rate of exacerbations in patients with severe COPD who frequently experience flare-ups and have elevated blood eosinophil levels.

This treatment represents a step forward in precision medicine for COPD, allowing for more targeted therapies based on individual patient characteristics.

Current treatments for COPD, primarily bronchodilators and corticosteroids, mainly focus on symptom relief and do not effectively address the underlying inflammation or prevent disease progression.

There is a need for new anti-inflammatory therapies, and targeted biotherapy may improve COPD management by identifying novel biomarkers and understanding the inflammatory processes involved in the disease.

In a pooled analysis of the TOZURA study involving 1804 patients with moderate to severe rheumatoid arthritis (RA), subcutaneous tocilizumab (TCZ-SC) demonstrated significant efficacy in reducing disease activity, with similar results whether used alone or in combination with conventional synthetic DMARDs.

The safety profile of TCZ-SC was confirmed, with a low rate of serious adverse events (5.8%) and a withdrawal rate of 13.9%, indicating that TCZ-SC is a safe and effective treatment option for patients who have not responded adequately to previous therapies.

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 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.

In early rheumatoid arthritis, treatment with tocilizumab (TCZ) combined with methotrexate (MTX) showed a greater reduction in disease activity (DAS28) and higher remission rates compared to the traditional MTX plus prednisone treatment over 24 months, with TCZ+MTX showing a mean difference of -0.62 in DAS28 scores.

While TCZ-based strategies demonstrated better outcomes in terms of disease activity and remission, some of these benefits may be influenced by the effect of TCZ on acute phase reactants, suggesting that the observed improvements might not be solely due to the treatment's efficacy.

Tocilizumab, an anti-IL-6R antibody, significantly inhibited the growth of non-small cell lung cancer (NSCLC) cells by 10-40%, showing effectiveness comparable to traditional chemotherapy drugs like methotrexate and 5-fluorouracil.

The treatment with tocilizumab led to an accumulation of NSCLC cells in the sub-G1 phase, indicating apoptosis induction, and suggested activation of the NFκB pathway, highlighting its potential as a new therapeutic option for NSCLC.

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.
