Zambon Unveils Promising Phase 3 Results for Lung Treatment

Zambon Announces Phase 3 Study Breakthrough for Lung Therapy

Zambon, a leading multinational pharmaceutical company dedicated to enhancing health and patient quality of life, has made significant strides in respiratory disease treatment. Their recent online publication in a reputable journal highlights the Phase 3 PROMIS-I and PROMIS-II studies, showcasing the efficacy of the inhaled colistimethate sodium delivered via the innovative I-neb Adaptive Aerosol Delivery System. This treatment aims to reduce the occurrence of pulmonary exacerbations in patients suffering from Non-Cystic Fibrosis Bronchiectasis (NCFB) who are chronically colonized with P. aeruginosa.

Significance of the PROMIS Studies

The PROMIS studies are pioneering efforts in quantifying the effectiveness of inhaled colistimethate sodium, a well-established antibiotic in Europe, particularly for Cystic Fibrosis. The trials were structured to evaluate treatment over a 12-month period against placebo, focusing on pivotal metrics like the frequency of pulmonary exacerbations.

Pivotal Data and Outcomes

“The publication of these crucial data underscores our commitment to advancing innovative treatments for severe respiratory conditions,” stated Paola Castellani, Chief Medical Officer and R&D Head at Zambon. “For patients with NCFB, conditions that currently lack approved treatment options, the PROMIS results reveal the potential of CMS I-neb to enhance patient outcomes and their overall quality of life. We are eager to collaborate with regulatory authorities to expedite patient access to this vital therapy.”

Pulmonary infection with P. aeruginosa often leads to more severe disease progressions, exacerbations, hospitalizations, and increased mortality rates. The PROMIS trials stand as the first large-scale, double-blind, placebo-controlled studies involving inhaled colistimethate sodium in this patient population.

Trial Parameters and Findings

The findings emerged from global Phase 3 multicenter studies that randomized adult patients with bronchiectasis. Specifically, participants had a history of multiple exacerbations requiring antibiotic treatment within the past year. The study involved 377 participants in PROMIS-I and 287 in PROMIS-II, with treatment regimens administered twice daily for up to a year.

Key Findings from PROMIS Trials

The PROMIS-I trial demonstrated a significant reduction in the annual exacerbation rates by 39% compared to the placebo group. Notable reductions were observed in severe exacerbation rates as well, being decreased by 59%. Patients also reported improvements in their quality-of-life metrics, driven by the St. George’s Respiratory Questionnaire, alongside reduced P. aeruginosa density in the airways.

Although the PROMIS-II study encountered disruption due to external factors, preliminary sub-analysis showed results consistent with PROMIS-I. Furthermore, participants across both trials exhibited good tolerability of the treatment, with minimal safety concerns reported.

Expert Opinions on the Results

Experts are praising the PROMIS program for its groundbreaking implications. Dr. Charles Haworth, an esteemed respiratory physician, commented, “This data represents a major breakthrough for patients with NCFB, who previously had limited effective treatments available. For the first time, we show that CMS I-neb has the potential to significantly reduce exacerbations and enhance quality of life, promising hope for this underserved population.”

Additionally, Professor James Chalmers emphasized, “The findings highlight the critical role inhaled antibiotics like CMS I-neb play in managing NCFB and the associated chronic infections, which drive inflammation and lung damage. Mitigating exacerbations correlates strongly with better health outcomes and lung function.”

Zambon's Long-Term Commitment

The PROMIS program has gained recognition through FDA Fast Track and Breakthrough designations, aiming to alleviate the burden of pulmonary exacerbations in adults dealing with NCFB conditions linked to P. aeruginosa. These accolades reflect Zambon’s steadfast dedication to advancing treatment options for respiratory diseases.

Understanding NCFB and Its Treatment

Non-cystic fibrosis bronchiectasis is an escalating chronic lung condition characterized by recurrent infections and persistent cough attributed largely to Pseudomonas aeruginosa. The need for effective treatment options grows as the incidence rises globally, especially among women and older populations. The ultimate goals in treating bronchiectasis include symptom management, exacerbation prevention, and enhancing patient quality of life.
