Cystic Fibrosis Australia and Phage Australia survey: Understanding clinical needs and attitudes towards phage therapy in the CF community

Cystic fibrosis (CF) is the most prevalent serious inherited disease in Australia, imposing significant health risks. CF is characterised by chronic lung inflammation and recurrent pulmonary infections that increase morbidity and premature mortality rates. The emergence of antimicrobial resistance (AMR) places further challenges on the treatment and management of CF, necessitating research into alternative strategies for treatment of bacterial infections. Bacteriophage therapy, involving bacterial-specific viruses, is a potential avenue for AMR infections in patients with CF. Existing literature supports the feasibility of phage therapy in CF but there has been a gap in investigating attitudes of the CF community including affected individuals and their caregivers, regarding phage therapy. Understanding perspectives and needs of the CF community is essential for successful implementation and acceptance of novel therapies including phage therapy. We conducted a survey that encompasses responses from 112 consumers from across Australia, comprising people living with CF (38.4%), parents of affected children (49.6%), carers (6.4%), and family members (3%). The findings showed a significant reliance on antibiotics with 51.4% requiring oral, 43.4% nebulised, and 11.4% intravenous (IV) antibiotics within the preceding 2 weeks. Respondents highlighted the availability of new treatments, duration of hospitalisations and costs associated with treatment as important priorities to address. Despite an awareness of phage therapy among 62.4% of respondents, 86.4% expressed interest in obtaining more information, primarily from medical staff (66.7%). Notably, 96.0% of respondents expressed willingness to participate in phage therapy trials. The results of this survey highlighted the CF community’s strong interest in advanced therapeutic approaches, specifically phage therapy. The findings reveal a notable recognition and acceptance of phage therapy as a viable treatment option for pulmonary infections associated with CF. ### Competing Interest Statement The authors have declared no competing interest. ### Funding Statement Australia's Medical Research Future Fund (MRFF) Frontiers Stage 1 grant.

Yes The details of the IRB/oversight body that provided approval or exemption for the research described are given below: Cystic Fibrosis Australia waived ethics oversight as this is an anonymous online research survey. I confirm that all necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived, and that any patient/participant/sample identifiers included were not known to anyone (e.g., hospital staff, patients or participants themselves) outside the research group so cannot be used to identify individuals. Yes I understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov. I confirm that any such study reported in the manuscript has been registered and the trial registration ID is provided (note: if posting a prospective study registered retrospectively, please provide a statement in the trial ID field explaining why the study was not registered in advance). Yes I have followed all appropriate research reporting guidelines, such as any relevant EQUATOR Network research reporting checklist(s) and other pertinent material, if applicable.
