What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing astegolimab, a medication for COPD, in people who have already completed a previous study. The goal is to see if it is safe and effective over a longer period by reducing lung inflammation to improve breathing.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

How is the drug Astegolimab unique for treating COPD?

Astegolimab is unique because it is a monoclonal antibody that targets the ST2 receptor, blocking interleukin-33 signaling, which is different from most COPD treatments that focus on bronchodilation or anti-inflammatory effects. This mechanism is novel for COPD, as it was previously studied in severe asthma, suggesting a different approach to managing respiratory conditions. ^{1 2 3 4 5}

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

Astegolimab has shown effectiveness in patients with severe asthma by reducing asthma exacerbation rates and improving lung function at higher doses, suggesting potential benefits for similar respiratory conditions like COPD. ^{1 3 5 6 7}

Are You a Good Fit for This Trial?

This trial is for people with chronic obstructive pulmonary disease (COPD) who completed a previous 52-week study of Astegolimab. They can't join if they've developed asthma, other significant lung diseases, serious heart conditions, or had non-compliance issues in the earlier study.

Inclusion Criteria

Exclusion Criteria

I have been diagnosed with asthma based on recognized guidelines since joining the main study.

I haven't had new heart issues or a heart attack since joining the main study.

I have not developed any new significant lung conditions other than COPD since joining the study.

Published Research Related to This Trial

Astegolimab, a monoclonal antibody targeting the ST2 receptor, was evaluated in a phase 2b study involving 368 patients with uncontrolled severe asthma, showing typical pharmacokinetic behavior for monoclonal antibodies.

The study found that the highest tested dose of 490 mg every 4 weeks approached maximum efficacy, indicating that increasing the dose further may not yield additional benefits in reducing asthma exacerbations.

A 68-year-old patient with stage IV lung adenocarcinoma showed an unexpected positive response to paclitaxel after failing treatment with pembrolizumab, an anti-PD-1 immunotherapy.

The patient experienced a response duration of over fourteen months with paclitaxel, suggesting that combining or sequencing chemotherapy with immunotherapy may enhance treatment effectiveness in certain cases.

In the phase Ib KEYNOTE-001 study, pembrolizumab monotherapy showed durable antitumor activity in advanced non-small-cell lung cancer (NSCLC), with a median overall survival (OS) of 22.3 months for treatment-naive patients and 10.5 months for previously treated patients, and 5-year OS rates of 23.2% and 15.5%, respectively.

Patients with a PD-L1 tumor proportion score of 50% or greater had even better outcomes, with 5-year OS rates of 29.6% for treatment-naive and 25.0% for previously treated patients, while the treatment maintained a favorable safety profile with minimal late-onset adverse events.

Tezepelumab, a monoclonal antibody approved for severe uncontrolled asthma, significantly improved forced expiratory volume (FEV1) by 0.15 L and reduced asthma exacerbation rates by 0.60 per year compared to placebo, based on a meta-analysis of six trials with 2667 patients.

The treatment was found to have an acceptable safety profile, with no higher incidence of adverse drug reactions compared to placebo, indicating it is a safe option for patients with severe asthma.

Pembrolizumab, an anti-PD-1 antibody, is effective as a first-line treatment for advanced nonsmall cell lung cancer (NSCLC) in patients with high PD-L1 expression (≥50%) and as a second-line option for those with lower PD-L1 expression (≥1%).

When combined with standard chemotherapy, pembrolizumab has demonstrated superior clinical outcomes compared to chemotherapy alone in patients with advanced NSCLC without targetable mutations, regardless of their PD-L1 expression levels.

In a 52-week study involving 65 Japanese patients with severe uncontrolled asthma, tezepelumab was found to be safe and well-tolerated, with most adverse events being mild to moderate, and only one case leading to treatment discontinuation.

Tezepelumab significantly reduced asthma exacerbation rates (0.11 per patient-year) and improved lung function and asthma control, with a 71.4% responder rate at Week 52, indicating its efficacy in managing severe asthma.

Tezepelumab, a monoclonal antibody for severe asthma, showed an acceptable safety profile in a phase 1 study with 24 healthy Japanese men, with no serious adverse events reported and no participants developing antibodies against the drug.

The pharmacokinetics of tezepelumab demonstrated linear absorption and a long half-life of approximately 24 days, indicating it is well-tolerated and may provide sustained therapeutic effects.
