Clinical Trial Opportunity for Phase IV Airway Clearance System

Med Systems is sponsoring a Phase IV clinical study to measure the
effectiveness of the Electro Flo 5000 Airway Clearance System for
people who have been diagnosed with cystic fibrosis. The goal of the
study is to provide health insurers and Medicare with comprehensive
information regarding the system’s performance. The study is designed
to measure the efficacy of the system, which includes the FDA510K
(K031876) device under current indications. The study will last 30 days
and involve using the system for lung clearance and recording the
results in a digital journal. The study should take about 10 minutes per
day to record measured results in the morning after waking. You will
also be asked to use a spirometer and a digital pulse oximeter to
evaluate your lung function after using the Electro Flo 5000 Airway
Clearance System.

Interested participants must be:
 Between the ages of 18-55 years of age
 Diagnosed with cystic fibrosis
 Prescribed chest physical therapy for airway clearance
 Able to perform self-treatment- having manual dexterity
 Residing in the United States

Therapy for Reducing P. Aeruginosa Lung Infections Planned Phase 1 Trial

Arch Biopartners recently completed a good manufacturing practice (GMP) production campaign for AB569, a potential inhalation treatment for antibiotic-resistant bacterial lung infections in people with cystic fibrosis (CF) chronic obstructive pulmonary disease (COPD) and other conditions. The campaign, intended to ensure the quality of the investigative therapy, was directed by Dalton Pharma Services.

AB569 is composed of ethylenediaminetetraacetic acid (EDTA) and sodium nitrite, two compounds approved by the U.S. Food and Drug Administration (FDA) for use in people. AB569 can be administered alone or in combination with other compounds to treat multi-drug resistant bacterial infections that can cause reduced lung function.

Pseudomonas aeruginosa is one of the most common bacterial infections in patients with respiratory diseases, including CF, COPD, and pneumonia.

In preclinical studies, AB569 was shown to be capable of killing drug-resistant bacteria like P. aeruginosa and other common pathogens associated with chronic lung infections.

The company also announced that a Phase 1 clinical trial to investigate the safety and pharmacokinetic profile of AB569, planned to start in January, will be conducted at the Cincinnati Veterans Affairs Medical Center (CVAMC). According to an Arch Biopartners press release, Ralph Panos, chief of medicine at CVAMC, will lead the trial.

Three escalating doses of nebulized AB569 will be used to evaluate tolerance to the treatment in about 25 healthy volunteers. Each will be given a single administration of nebulized AB569  to characterize the pharmacokinetic profile of plasma nitrite and nitrate metabolites, exhaled nitric oxide, and circulating hemoglobin.

Pharmacokinetics studies how a drug is absorbed, distributed and metabolized in, and expelled by, the body.

Should the Phase 1 trial in volunteers be successful, Arch Biopartners plans to move its AB569 program into a Phase 2 trial to test its effectiveness in treating chronic P.aeruginosa infections in COPD patients.

AB569 received orphan drug status by the FDA in November 2015 as a potential treatment of P. aeruginosa lung infections in CF patients. Orphan drug status is given to investigative medicines intended for people with rare diseases to speed their development and testing.

New Promising Results from Phase 3 of Combination Therapy

Findings from a phase 3 trial evaluating the efficacy and safety of tezacaftor in combination with ivacaftor in patients with cystic fibrosis (CF) who were homozygous for the Phe508del mutation were published in the New England Journal of Medicine.

The Phe508del mutation has been known to result in greatly reduced conductance regulator (CFTR) protein activity and a loss of chloride secretion, which can lead to impaction of mucus in the airways, gastrointestinal tract, and exocrine organs, with the potential for severe clinical consequences including gradual loss of lung function, nutritional deficits, pulmonary exacerbations, and respiratory failure. It is the most prevalent CFTR mutation worldwide, and affects approximately 46% of American CF patients.

Previous data has shown Ivacaftor’s association with a rate of progressive decline in lung function that is lower than that in untreated patients. In a phase 2 clinical trial involving patients who were homozygous for the Phe508del mutation or heterozygous for the Phe508del and G551D mutations, when combined with the investigational CFTR corrector tezacaftor, it has exhibited enhanced CFTR function and improved lung function.

In August, just one month removed from Vertex’s announcement of positive datafrom Phase 1 and Phase 2 studies, Rare Disease Report covered the acceptance of applications for the use of the tezacaftor/ivacaftor combination treatment in this patient population by the U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA).

The phase 3 trial enrolled a total of 510 patients 12 years and older with CF who were homozygous for the Phe508del CFTR mutation at 91 sites in the U.S., Canada, and Europe from January 30, 2015 to January 20, 2017. Patients were randomly assigned to be administered either tezacaftor and ivacaftor (administered as a fixed-dose combination tablet containing 100 mg of tezacaftor and 150 mg of ivacaftor in the morning and a tablet containing 150 mg of ivacaftor in the evening) combination therapy or placebo for 24 weeks.

In total, 475 patients completed the full 24 weeks of the trial, with 93.6% (n=235) in the tezacaftor-ivacaftor group and 93% (n=240) in the placebo group. While no significant difference in the body mass index (BMI) was experienced between the groups at week 24, the use of the combination therapy led to a significantly greater absolute change from baseline in the predicted forced expiratory volume in 1 second (FEV1) than placebo. Despite advances in standard-of-care therapy, patients with CF continue to lose lung function at a rate of an estimated 1% to 3% per year. This trial exhibited a significant effect of the combination therapy compared to the placebo, as the mean absolute change from baseline in FEV1 through week 24 was 3.4 percentage points in the former, compared to 0.6 in the latter.

The most common adverse events (AEs) among the enrolled patients included infective pulmonary exacerbation, cough, headache, nasopharyngitis, increased sputum production, pyrecia, hemoptysis, oropharyngeal pain, and fatigue. The incidence of AEs was similar in both the group for combination therapy and the placebo group, however, those treated with lumacaftor-ivacaftor in the phase 3 did not experience an increased incidence of respiratory events (33 patients [13.1%] vs. 41 patients [15.9%]).

This improved safety profile of the tezacaftor-ivacaftor combination supports its use in a broad range of patients with CF, and, if approved, the therapy will be the third of Vertex’s drugs approved for CF patients, and the second intended specifically to treat patients with F508del mutations (Orkami [lumacaftor/ivacaftor]).

Vertex Drug Gets Priority Review for Cystic Fibrosis

Tezacaftor/Ivacaftor Gets Priority Review for Cystic Fibrosis

The Food and Drug Administration (FDA) has granted Priority Review to the New Drug Application (NDA) of tezacaftor/ivacaftor (Vertex) for the treatment of patients ≥12yrs old with cystic fibrosis (CF) who have two copies of the F508del mutation or one F508del mutation and one residual function mutation.

The NDA submission was based on positive results from 2 global Phase 3 trials, which showed statistically significant improvements in lung function (percent predicted forced expiratory volume in one second, or ppFEV1) in patients treated with tezacaftor/ivacaftor.

The combination treatment consists of ivacaftor (marketed under the brand name Kalydeco), a cystic fibrosis transmembrane conductance regulator (CFTR) potentiator, and tezacaftor, a novel CFTR corrector. Tezacaftor is designed to address the processing defect of F508del-CFTR to enable it to reach the cell surface, where ivacaftor can further enhance the protein’s function.

The FDA has set a Prescription Drug User Fee Act (PDUFA) target date of February 28, 2018 to make a decision on the NDA.
