Phase 2
Recruiting
Research Sponsored by SpliSense Ltd.
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Diagnosis of CF and two CF causing mutations; 3849+10 Kb C->T mutation on one allele in the CFTR gene (homozygote or compound heterozygote). Source documentation from a certified genetic laboratory is required.
Non-smokers or vapers for at least 180 days (6 months) prior to screening, per participant report.
Must not have
Documented coronavirus disease (COVID-19) infection within 4 weeks prior to dosing.
Use of any investigational drug (other than SPL84) or device within 30 days of first dose with study intervention.
Timeline
Screening 3 weeks
Treatment Varies
Follow Up day 1 through day 87

Summary

This trial aims to determine if the drug SPL84 is safe and effective for treating cystic fibrosis (CF) in adult patients, specifically those with a certain mutation. Participants will inhale the drug

Who is the study for?
Adults with cystic fibrosis can join this trial. They'll use an inhaler to take SPL84 or a placebo weekly for over two months and visit the clinic about 14 times in that period. The study will check if they have a specific CF mutation.
What is being tested?
The trial is testing SPL84, a new drug for cystic fibrosis, against a placebo (a substance with no active drug). It aims to determine the safety of multiple doses and how well it treats CF when taken by inhalation.
What are the potential side effects?
Specific side effects are not listed, but generally, participants may experience reactions related to inhaling medication such as coughing, throat irritation or potentially other symptoms which will be monitored.
