Synspira’s Therapy Candidate May Be a Game-Changer for Drug-Resistant Bacteria in CF – Cystic Fibrosis News Today

Chronic pulmonary infections are a hallmark of lung disease in patients with cystic fibrosis. Due to the variability in bacteria that can colonize the lung and the specific antibiotic treatments that may be effective, treatment strategies are often tailored to individual patients.

But some bacterial infections are often difficult to treat across the entire population. Burkholderia cepaciacomplex (Bcc) is notoriously difficult to attack due to its natural multi-drug resistant state and its quick ability to develop resistance to antibiotics. Infections arising from Bcc can lead to permanent loss of lung function and early death in patients with CF.

Earlier this month, Synspira announced the resultsof a combination study using its inhaled polycationic glycopolymer drug candidate called PAAG and conventional antibiotics as a potential treatment for pulmonary infection caused by theBurkholderia cepaciacomplex in patients with CF.

The investigative treatment, SNSP113, is a glycopolymer-based therapy being developed as an inhaled treatment to improve lung function in patients with pulmonary bacterial infections.

SNSP113 is known to interact with the biofilms that make treating bacteria difficult in CF, and is thought to break the biofilms apart and reduce the viscosity and adhesion of mucus in the lungs. Biofilms and mucus lead to pulmonary exacerbations in CF, and SNSP113 may address both issues in cystic fibrosis.

The results published in PLOS ONE demonstrate that our inhaled glycopolymer drug candidate, PAAG, has the potential to significantly enhance the activity of antibiotics that are used for the treatment of lung infections caused by Burkholderia cepaciacomplex, a relatively uncommon but often fatal infection in cystic fibrosis,Shenda Baker, PhD,the CEO ofSynspira, said in a press release.

From a personal viewpoint, Bcc is one of those bacteria that makes me anxious to see my culture report. Its a scary one, and requires an intensive treatment plan in hopes to eradicate the bacteria from the lungs.

Part of the reason its nerve-racking is because there really are no bulls-eye treatments that have been approved to help preserve lung function. The bacteriums susceptibility to antibiotics varies tremendously, and there is a chance that no antibiotic may be effective to fight the infection.

The introduction of SNSP113 could be a game-changer in CF. If approved, the treatment would not only open up treatment options for Bcc, but may also have positive outcomes when treating other common infections in CF, like Pseudomonas. While much of the attention in cystic fibrosis has been directed toward the novel CFTR modulators, its still critically important to strive for new antibiotics in patients with CF.
