What is the purpose of this trial?

This trial tests a new treatment called buloxibutid for individuals with idiopathic pulmonary fibrosis (IPF), a lung disease that causes scarring and breathing problems. The trial aims to evaluate the effectiveness and safety of the medicine, either alone or with other IPF treatments. Participants will receive either buloxibutid or a placebo (a non-active substance) for 52 weeks. Those who have had IPF for less than 7 years and are either on a stable IPF treatment or not on any treatment might be suitable candidates. For more details, visit www.aspire-ipf.com. As a Phase 2 trial, this research focuses on assessing the treatment's effectiveness in an initial, smaller group of people.

Will I have to stop taking my current medications?

If you are on a stable dose of licensed IPF therapy, you can continue taking it during the trial, except for pirfenidone, which is not allowed. If you are not currently on IPF treatment, any previous IPF therapy must have been stopped more than 8 weeks before joining the trial.

Is there any evidence suggesting that buloxibutid is likely to be safe for humans?

Research has shown that buloxibutid is safe and well-tolerated in previous studies. In a 36-week trial, mild-to-moderate hair loss was the main side effect, which resolved after discontinuing the treatment. No other major side effects were reported. These findings suggest that buloxibutid could be a promising option for people with idiopathic pulmonary fibrosis (IPF).12345

Why do researchers think this study treatment might be promising?

Most treatments for pulmonary fibrosis, like pirfenidone and nintedanib, work by slowing disease progression. But Buloxibutid is unique because it targets a different pathway that may directly impact lung tissue repair. Researchers are excited about Buloxibutid because it offers a new mechanism of action that could potentially improve lung function more effectively. With its novel approach and the possibility of better outcomes for patients, Buloxibutid stands out as a promising new option in the fight against this challenging condition.

What evidence suggests that buloxibutid might be an effective treatment for pulmonary fibrosis?

Studies have shown that buloxibutid, an oral medication, can help people with idiopathic pulmonary fibrosis (IPF) breathe better. This medication activates a specific mechanism in the body that protects the lungs from damage. In a previous study, patients who took buloxibutid showed noticeable improvements in lung health over 36 weeks. These findings suggest that buloxibutid might slow lung damage in people with IPF. The trial will evaluate different dosages of buloxibutid, specifically 100 mg and 50 mg taken twice daily, compared to a placebo, over a 52-week period. This offers hope for those facing this challenging condition.16789

Published Research Related to This Trial

In a study of 92 patients with idiopathic pulmonary fibrosis (IPF) receiving pirfenidone, the drug showed an acceptable safety profile, with skin-related (25%) and gastrointestinal (17.5%) adverse events being the most common, leading to discontinuation in 22.5% of cases.
Despite some patients experiencing significant improvements in lung function, the overall decline in lung function (%FVC and %DLCO) was noted over 36 months, highlighting the need for further research through prospective observational registries to better understand pirfenidone's long-term efficacy in real-world settings.

In a study involving rats, halofuginone was found to significantly reduce pulmonary fibrosis caused by bleomycin, indicating its potential as a treatment option for this serious condition.
The treatment was administered every second day over a 42-day period, and the results showed a marked decrease in collagen levels in the lungs, highlighting halofuginone's effectiveness in inhibiting collagen type I synthesis associated with fibrosis.

A series of novel derivatives of pirfenidone were designed and synthesized to find new treatments for pulmonary fibrosis, showing promising results in preliminary studies.
Most of these new compounds demonstrated significantly better anti-pulmonary fibrosis activity compared to the original drug, pirfenidone, indicating potential for improved therapeutic options.
