SEATTLE, Sept. 25, 2018 /PRNewswire/ — Sound Pharmaceuticals (SPI) is pleased to announce that its recent submission to the upcoming North American Cystic Fibrosis Conference (NACFC) Oct. 18-20 has been selected as a late-breaking abstract. This presentation will focus on the incidence and severity of ototoxicity in CF patients undergoing intravenous (IV) tobramycin treatment for acute pulmonary exacerbation. Ototoxicity (hearing loss, tinnitus, vertigo or dizziness) is a common side effect of tobramycin and other aminoglycoside antibiotics (amikacin, gentamycin and streptomycin). Currently, there are no FDA approved therapies for the prevention or treatment of ototoxicity or any other type of sensorineural hearing loss, tinnitus, or dizziness.

When acquired in patients with cystic fibrosis, clinical outcomes are known to be even worse, affecting several organs—primarily the lungs—and resulting in an increased rate of declined respiratory function as well as infections that can have severe, and sometimes deadly, consequences.
Now, however, for the first time, investigators have found that telavancin—a drug that is currently used to treat skin infections and hospital-acquired pneumonia—has potent in vitro activity and low resistance development potential when used against S aureus isolates in patients with cystic fibrosis, making it a promising potential treatment option for this population.
“Telavancin (TLV) is a lipoglycopeptide antibiotic approved by the US Food and Drug Administration in 2009 for the treatment of complicated skin and skin structure infections and in 2013 for the treatment of cases of nosocomial pneumonia, however its application for the treatment of CF-MRSA pneumonia infections was not known, so our studies are contributing to extending the application of TLV for CF treatment,” Adriana E. Rosato, PhD, associate professor in the department of Pathology and Genomic Medicine at Houston Methodist Research Institute told Contagion®. “We were also inspired by the fact that CF patients have a short life time—until 40 to 50 [years]—so our priority is to contribute to better treatment in this patient population.”
Dr. Rosato and her team hypothesized that TLV might be a promising treatment option for CF-patient-derived MRSA and MSSA infections, as in vitro studies have shown that TLV has activity against MRSA.
To prove this, the investigators screened a total of 333 strains of CF patient-derived S aureus of the wild-type or small-colony-variant phenotype, collected from both adults and children at 3 different cystic fibrosis centers: Houston Methodist Research Institute, UW Health and the Center for Global Infectious Disease Research. TLV was found to display activity against all 333 strains collected.
When testing the activity of the drug against 23 MRSA strains, the investigators observed intermediate resistance to ceftaroline (CPT)—a new beta-lactam antibiotic that targets PBP 2a in MRSA—in 20 of the strains, and high-level resistance to CPT in 3 of the strains. The authors note that although high levels of resistance to CPT is rare, intermediate resistance is more common in patients who have chronic infections.
“Among all strains, the TLV MIC90 was 0.06 mg/liter, i.e. 8-fold lower than the daptomycin (DAP) and CPT MIC90 and 25-fold lower than the linezolid (LZD) and vancomycin (VAN) MIC90,” the authors write.
Using time-kill experiments, the investigators assessed the in vitro effectiveness of TLV compared with DAP, VAN, and CPT. They found that TLV showed activity against all tested strains and displayed rapid bactericidal activity as well. The activity profile for the drug at a free serum concentration of 8 mg/liter showed that TLV performed better than VAN (16 mg/liter), LZD (10.4 mg/liter), and CPT (16 mg/liter).
The investigators also set out to determine the fate of mutation selection that could be projected by the potential prolonged use of TLV in patients with cystic fibrosis. To do this they looked at 3 specific strains: AMT 0114-48, WIS 664, and TMH 5007. They found that due to the ease of mutation selection which had been noted in control strains, TLV mutant resistance is independent of the CF patient background of the strains.
“We demonstrated that TLV has bactericidal activity against the S aureus strains tested, including those against which CPT and LZD displayed reduced activity, which might provide TLV a significant advantage over the drugs currently used to eradicate those strains and prevent future exacerbations,” the study authors write.
A clinical trial is currently underway to assess the pharmacokinetic profile of TLV in patients with cystic fibrosis, who usually need dose adjustment because of an increase in the volume of distribution and clearance.
“[The next step for our research is] to perform in-vivo analyses studies that could lead to translational application/clinical trial,” Dr. Rosato added. “However, we are limited in research funds to continue our investigations.”

So many fears, where do I begin. Let’s start with my impending trip to Seattle from NYC. I like to travel but it gets complicated. How much room in my suitcase do I have to pack my myriad of machines and meds? And how much will I forget, despite my thorough list? I learned I had to put obvious things on my list like a hairbrush after I forgot that a few times. But when it is easily purchased at a drug store, no biggy. When it is my immune suppressants or a nebulizer, that is harder to replace.
I now have a lot more machinery to tote around when I leave home. I have my CPAP, my percussor and my inhalation machine and a facial steamer for my sinuses, plus my Neti pot for nasal lavage. These things become cumbersome and traveling light is not an option, I have to check my bag. So, planning is key for several days prior to take off. I am in that phase now. Packing it all. I bring enough meds for twice my travel time. My last trip to Seattle happened during 9/11. I could not fly home for a week. Luckily, I had an extra 10 days of medications to cover me.
My dad asked if I was up to the flight, it is a longer one than I have taken in many years. My answer is, I don’t know. I am fearful as I know I have lymphedema and even though I wear compression tights when I fly, it is less than comfy and I will swell in my upper body. I do have a compression machine for upper body swelling but it is way too big to bring. Will I be ok not using it for a few days? I am hoping the answer is yes. But because I do not know these things for certain, I have anxiety. And I worry I might get sick either from the flight or anytime during my trip. I do wear a mask in flight and try to stay as hydrated as possible in order to keep well. And of course, I will wipe down the area near my seat with cleaning wipes.
But in order to live a life, I have to take some risks. I had wanted to go to Seattle for a few years. It is therapeutic to get away once in a while and I had not traveled too far from home while my mom was alive. I wanted to be near enough if she needed me. I no longer have that worry. And maybe I used that as an excuse so I am now pushing myself to go on this trip. I know I can be resourceful and my doctors are only a phone call away if I get sick. There is a great CF center there and my friend is sensitive to my CF needs. When we were in college together she gave my CPT when I let her.
I find that when I push myself beyond my fears, I feel triumphant and am happy that I conquered them. Sometimes one has to get out of their comfort zone, even if it means wearing horribly tight pantyhose for six hours on a flight! I know it will be worth it and I can bond with my friend. I will feel like I accomplished something worthwhile. Maybe my next trip will be to Europe.

Nancy Wech, Lauren’s mother, established this scholarship in Lauren’s name and memory. In Nancy’s own words:
Lauren Melissa Kelly was an extraordinary woman. Laughing, gregarious, spontaneous, fun, talkative, driven, thoughtful, smart, kind and loving — all descriptive terms for Lauren, who lost her battle with CF late in her senior year at the University of Georgia. In 1992, Lauren was chosen as one of ten Senior Leaders at University of Georgia. She had distinguished herself as a member of the Golden Key Honor Society, Mortar Board, Phi Upsilon Omicron, Gamma Beta Phi, the Tate Society and Delta Gamma sorority.
Lauren felt the most significant opportunities of her college career included participation in the reconstruction and formation of organizations, which will serve the university in the future. She acted as one of the re-founding members of the Phi Kappa Literary Society and was significant in the metamorphosis of the Z Club into the William Tate Society. Her other activities included Greeks Advocating Mature Management of Alcohol (GAMMA) in which she served as Secretary and Special Events Chair. She was also a member of the Women’s Glee Club for more than two years.
In recognition of her academic performance, Lauren’s degree of Bachelor of Science in Family and Consumer Sciences was awarded posthumously. At the time of her death, Lauren was engaged to be married and living off campus in an apartment. She lived life to the fullest!
Walt Disney said, “Don’t cry because it’s over, smile because it happened. It’s not the days in life you remember, it’s the moments.” As Lauren’s mother stated, “I smile because she happened to me. Now, I want you to smile because she has happened to you.”

A note from CF Roundtable: Please do not stop using your Vest or other HFCWO device because of this impractical study. There are important differences in this study that make it not applicable to CF and therefore, not meaningful for us. First, healthy volunteers without CF were enrolled. Too many adults with CF have experienced significant benefits with these HFCWO devices, not to mention the preventive benefits. To imply these devices worsen lung function when used by a healthy nonCF person vs one with CF – with the usual accompanying inflammation, mucus +/- bronchiectasis, etc – is not practical. Second, these healthy subjects tested all 4 HFCWO devices in one day. Even when I repeat spirometry in one day, my lung function numbers most often decline over time, even with rest periods in between. The researchers tested lung function with a rest period of 15 minutes on these healthy individuals after use of the HFCWO device then moved on to the next device. Very impractical and again – not applicable to use by individuals with CF.

A clinical study into high-frequency chest wall oscillation vests — assessing their short-term impact on standard measures of lung function before and during use — challenges the view that these devices work through airflow bias in the lungs, the process responsible for mucus movement when breathing.
Findings, using established tests that include forced vital capacity (FVC), forced expiratory volume (FEV1), and forced expiratory flow (FEF25%-75%), suggest “that the concept of HFCWO vest-induced cephalad airflow bias is not supported by standard spirometry measurements,” researchers concluded. “None of the vest groups showed statistically significant increased airflow in the lungs.” Continue reading Airway Clearance Vests Fail to Show Measurable Short-term Lung Benefits in Study

Patient-reported outcome (PRO) measurement (e.g. health-related quality of life questionnaires, symptom diaries) can provide a standardized, valid and reliable way of gaining the patients’ perspective on ‘how they are’ or the benefits and limitations of a specific intervention. The insights that patients have concerning their health are important given that aspects of patient-reported quality of life are independent predictors of survival in cystic fibrosis (CF) . Regulatory authorities require the inclusion of PROs in clinical trials as an additional outcome parameter and PRO information is becoming important in labelling claims. It is noteworthy that the top 10 research questions, reached by global consensus of patient and healthcare providers, all require the inclusion of CF-specific PROs to achieve meaningful answers . This represents a significant paradigm shift but capturing data that matters to patients, families and clinicians is challenging. Two of the persistent challenges in CF PRO measurement are a) the development and use of technologies to enable efficient administration, accurate scoring, and the correct interpretation of data and b) being able to accurately measure PROs (or parental proxy assessment) across the entire CF lifespan. These important issues are considered by two papers in this issue of the Journal of Cystic Fibrosis [3, 4].
PRO measurement largely remains a research endeavour with little uptake in clinical practice. Administering, scoring and interpreting PROs in a busy clinic is difficult. It requires staff time and expertise and the results are not instantly accessible to steer a discussion with the patient or to aid clinical decision making. Paper-based data collection suffers from missing, unreadable data that is prone to scoring/mathematical error. The development of electronic PRO (ePRO) technologies is immensely important in clinical practice and for endpoint assessment in clinical trials. It is a cost-saving, patient-friendly approach to PRO assessment: data collection can occur in clinic, the patient’s home, workplace or school. Results can be added to a patient’s electronic medical file, alerts triggered by problematic scores and clinicians can track patient/parent-reported symptom/event data over time. Importantly, electronic data capture enhances the integrity and accuracy of the data, makes it logistically easier to collect repeated assessments (daily or at several points over a trial), and is preferred over paper-based data collection by the US Food and Drug Administration (FDA).
There is growing evidence that paper and electronic versions of PROs typically provide comparable data but this requires psychometric evaluation if transferring an original paper-based questionnaire to an electronic mode of administration. Solé and colleagues have demonstrated measurement equivalence with paper and electronic administrations of the Cystic Fibrosis Questionnaire-Revised (CFQ-R teen/adult version) . The e-CFQ-R web version is linked to an online database that can be adapted for any electronic devise (smartphone, tablet, computer). Immediately the patient completes the questionnaire, results are sent to the healthcare team and the data are saved in a centralized, protected database. Real-time patient-reported data are available to the clinician as an adjunct to clinical data. Access to the English and Spanish versions are by independent web addresses provided in the paper. Ultimately, the integration of PRO data within electronic care records as developed by Peckham et al. , or in CF patient registries would enable efficient patient care and longitudinal research endeavours.
There is a lack of PROs that can be used as endpoints in early intervention studies in CF. Such instruments are time-consuming and painstakingly difficult to develop so the research of Edwards et al. reporting on the initial development of a CF-specific, parent-reported instrument for children 0–11 years is welcome . The need for an effective way of data collection is also considered. The instrument takes the form of an electronic (web-based data capture), observational sign/symptom diary containing 17 respiratory and activity signs that parents report the presence or absence of. Results suggest that children aged 7 to 11 years are best reporting for themselves, therefore observational reporting by parents should focus on young children aged 0 to 6 years. Considerable evaluation has yet to determine the final instrument but the development of the scale follows FDA guidance enabling its acceptance as a clinical trial endpoint in infants and young children with CF.
Over the last twenty years we have learned a great deal about measuring patient-reported outcomes in CF, and there are many pitfalls when employing PROs in CF trials . They are typically secondary endpoints and the trial is not powered on them, often making it difficult to draw valid inferences about treatments. However, there are trials that have collected patient-reported respiratory symptom data as the primary endpoint [7, 8], employing the only CFQ-R subscale that has been approved by the FDA for use as an endpoint. Scientific, regulatory and pragmatic factors are driving the shift towards ePRO data collection. The development of ePROs is not trivial, yet they are fast becoming the ‘gold standard’ for PRO data capture in clinical trials. The challenge now is to develop CF-specific, lifespan PROs, utilising new technologies that can deliver real-time, high-quality PRO information. They also need to be acceptable to the regulatory bodies to aid their decisions on cost-effectiveness and ensure the appropriate commissioning of new medicines to improve the lives of people with CF and their families.

This Lung Life By Ella Balasa
I hear others say “I have CF. CF doesn’t have me.” This may be an accurate statement for some, the small percentage of patients who are not limited by this disease. Those who climb mountain peaks, work 60 hours a week, and raise three children. They could say this statement is true. They conquer everything, despite CF.
I am not one of these patients. I am optimistic, though. I’m optimistic that one day I will sprint faster than you (with transplanted lungs). I’m optimistic that I will leave this world having made some kind of impact on those around me, and maybe others that I am unaware of. But with this DNA in the cells of my lungs, I can’t do it all.
I’ve had significant events and minute moments in my life that have been affected by CF, although it’s not always apparent to the world around me. However, I don’t claim that CF has altered my life for the worst. Instead, I show the reality.
CF had me most recently when I was planning to go to the Cystic Fibrosis Research Inc.’s Family Education Conference. Being a director for the U.S. Adult Cystic Fibrosis Association, I wanted to connect with fellow CF directors and hear about the amazing new research the CF community is eager to benefit from. Unfortunately, due to CF infection guidelines and the bacteria I harbor in my lungs, I posed a risk to other CF patients, so I was restricted from attending.
Recently, as my form of exercise, I have been playing tennis. CF has me when it grasps my airways after just a few serves. I feel my lungs expanding but not getting enough air, exhausted from a previous sprint of just a few feet. I watch as the ball spins toward the far corner of the court. In my mind, my legs are in the air moving toward it, but in reality, they have just elevated the sole of my foot for the first step. The muscles are depleted of oxygen, waiting for the next burst for them to spring into action, but it never comes. Instead, they continue straining with what little reserve they have, for one-quarter of their potential. The quarter that comes from the lungs that function at one-quarter of what they should.
CF dictated the direction my life would take when upon graduation I was offered my dream job, but I didn’t take that career path. Spending four hours a day on breathing treatments, attending frequent doctor’s appointments, having occasional hospital stays and health insurance factors, as well as maintaining a social life and community involvement weren’t conducive to a full-time working schedule. Choosing not to advance in my career as my peers did made me feel left behind. Instead, keeping my health as the focus, I chose part-time employment.
CF has me when I have an exacerbation and lots of congestion in my lungs. On occasion during these times, I’ve taken the flight of stairs from the basement out into the sunshine after work. After a few steps outside, I feel the absence of air in my lungs. I gasp and then panic. Continue the article here.
