More importantly, use of the ointment promoted wound healing in those with the severe skin-blistering condition. Indeed, compared with placebo, a greater reduction in wound size was observed after 2 weeks when the ointment was applied (a mean reduction of 65.5% vs. 88.4%; P less than .006). However, at 1 month, no significant differences were seen in the size of the wounds between the two treatment arms.

“Calcipotriol is a vitamin D analog and it is well known that vitamin D is a very critical factor for skin homeostasis and proper wound healing,” Christina Guttmann-Gruber, PhD, said at the EB World Congress, organized by the Dystrophic Epidermolysis Bullosa Association (DEBRA). Dr. Guttmann-Gruber, a group lead researcher for EB House Austria, which is based at the Salzburg (Austria) University Clinic for Dermatology, noted that vitamin D also helps with tissue repair and immune modulation, and enhances local antimicrobial activity.

During an oral poster presentation at the meeting, Dr. Guttmann-Gruber explained that in previous in vitro studies, it was found that low concentrations (100 nmol) of calcipotriol inhibited proliferation of RDEB tumor cells (Sci Rep. 2018 Sep 7;8:13430). Calcipotriol (also known as calcipotriene) also was found to improve the expression of antimicrobial peptides and promote wound closure. “Therefore, we thought that applying calcipotriol at the site of injury, on chronic wounds prone to superinfection where it is needed, might be beneficial for our patients.”

She and her associates designed a two-arm, randomized, double-blind crossover study to assess the effects of an existing calcipotriol-containing ointment on wound healing in patients with RDEB. The ointment used in the study is approved for treating psoriasis but was adapted by the in-house pharmacy team to reduce the concentration of calcipotriol to about 0.05 mcg/g, or around 121 nmol. The reason for the reduction was that, at higher doses, keratinocyte proliferation was reduced, which would be detrimental in RDEB patients.

Nine patients were included in the study and were randomized to either apply 1 g of the active or placebo ointment to each of two designated wounds, of at least 6 cm2 in size, every day for 4 weeks. A 2-month washout period then followed before the groups switched to use the other ointment for 1 month. Six out of the nine patients completed both treatment phases. The reasons for the patients not completing both intervention phases were not related to the drug.



Calcipotriol treatment resulted in a significant and steady reduction in itch over the entire course of treatment, which was not seen among those on placebo, Dr. Guttmann-Gruber observed. The reduction in itch was “striking,” but only while the treatment was being used, she said. Results for pain were less clear, with a significant reduction in pain after 2 weeks seen only in the placebo group, while both treatments reduced pain to the same degree by 1 month.

No serious adverse events were observed at any time point and topical use of the low-dose calcipotriol did not significantly change serum levels of calcium or vitamin D in the two patients in which this was studied, Dr. Guttmann-Gruber said.

“This is an approved drug; it’s used in psoriasis, but at a very high concentration. We were able to use it off label and make a diluted version,” she observed. “Any pharmacy can do it.” Although it was applied topically, it could be done by applying it to the dressing rather directly onto the wounded skin, she said.

Data on the skin microbiome response to treatment were also collected but were not available to analyze in time for presentation, but it appeared that there was improvement with the low-dose calcipotriol treatment, Dr. Guttmann-Gruber said. “When the wounds are healing, the microbial flora is improving.”

The next step will probably be to plan a multicenter trial of this treatment, Dr. Guttmann-Gruber said in an interview. The questions is whether such a trial would get the financial backing it needed, but if an orphan drug designation could be obtained for calcipotriol for EB, then it would be possible to conduct such a trial.

The study was funded by DEBRA Austria. The presenting author, Dr. Guttmann-Gruber, had no conflicts of interest to disclose.

Losartan showing promise in pediatric epidermolysis bullosa trial

Article Type
Changed
Tue, 02/04/2020 - 12:01

– Treatment with the antihypertensive drug losartan raised no safety concerns in the treatment of children with epidermolysis bullosa (EB) and reduced signs of fibrosis in an early clinical study.

In the ongoing phase 1/2 REFLECT (Recessive dystrophic EB: Mechanisms of fibrosis and its prevention with Losartan in vivo) trial, involving 29 children, no severe complications have been noted so far, according to one of the study investigators, Dimitra Kiritsi, MD, of the University of Freiburg, Germany. At the EB World Congress, organized by the Dystrophic Epidermolysis Bullosa Association (DEBRA), she presented interim data on 18 patients in the trial, emphasizing that the primary aim of the trial was to evaluate the safety of this treatment approach.

Over the 2 years the trial has been underway, 65 adverse events have been reported, of which 4 have been severe. Two of these were bacterial infections that required hospital treatment and the other two were a reduction in the general health condition of the child.

Losartan is an angiotensin-II receptor blocker (ARB) that has been in clinical use for more than 25 years in adults and 15 years in children over the age of 6 years.

The drug may be used for treating recessive dystrophic EB (RDEB) in the future, Dr. Kiritsi said, because it attenuates tumor necrosis factor–beta (TGF-beta) signaling, which is thought to be involved in the fibrotic process. So while it may not target the genetic defect, it could help ameliorate the effects of the disease.

The precursor to REFLECT was a study performed in a mouse disease model of EB (EMBO Mol Med. 2015;7:1211-28) where a reduction in fibrotic scarring was seen with losartan with “remarkable effects” on “mitten” deformity, Dr. Kiritsi said. The results of that study suggested that the earlier treatment with losartan was started in the course of the disease, the better the effect, she added. (Mitten deformity is the result of fused skin between the fingers or toes, and the subsequent buildup of fibrotic tissue causes the hand or foot to contract.)

REFLECT is an investigator-initiated trial that started in 2017 and is being funded by DEBRA International. It is a dual-center, nonrandomized, single-arm study in which children aged 3-16 years with RDEB are treated with losartan for 10 months, with follow-up at 3 months.

Various secondary endpoints were included to look for the first signs of any efficacy: the Physician’s Global Assessment (PGA), the Birmingham Epidermolysis Bullosa Severity Score (BEBS), the Epidermolysis Bullosa Disease Activity and Scarring Index (EBDASI), the Itch Assessment Scale for the Pediatric Burn Patients, and two quality of life indices: the Quality of Life in EB (QOLEB) questionnaire and the Children’s Dermatology Life Quality Index (CDLQI).



Dr. Kiritsi highlighted a few of the secondary endpoint findings, saying that reduced BEBS scores showed there was “amelioration of the patients’ phenotype” and that EBDASI scores also decreased, with “nearly 60% of the patients having significant improvement of their skin disease.” Importantly, itch improved in most of the patients, she said. Reductions in CDLQI were observed, “meaning that quality of life was significantly better at the end of the trial.” There were also decreases in inflammatory markers, such as C-reactive protein, interleukin-6, and TNF-alpha.

Although there is no validated tool available to assess hand function, Dr. Kiritsi and her team used their own morphometric scoring instrument to measure how far the hand could stretch; their evaluations suggested that this measure improved – or at least did not worsen – with losartan treatment, she noted.

A larger, randomized trial is needed to confirm if there is any benefit of losartan, but first, a new, easy-to-swallow losartan formulation needs to be developed specifically for EB in the pediatric population, Dr. Kiritsi said. Although a pediatric suspension of losartan was previously available, it is no longer on the market, so the next step is to develop a formulation that could be used in a pivotal clinical trial, she noted.

“Losartan faces fewer technical hurdles compared to other novel treatments as it is an established medicine,” Dr. Kiritsi and associates observed in a poster presentation. There are still economic hurdles, however, since “with losartan patents expired, companies cannot expect to recoup an investment into clinical studies” and alternative funding sources are needed.

In 2019, losartan was granted an orphan drug designation for the treatment of EB from both the Food and Drug Administration and the European Medicines Agency, but its use remains off label in children. “We decided to treat children,” Dr. Kiritsi said, “because we wanted to start as early as possible. If you already have mitten deformities, these cannot be reversed.”

DEBRA International funded the study. Dr. Kiritsi received research support from Rheacell GmbH and honoraria or consultation fees from Amryt Pharma and Rheacell GmbH. She has received other support from DEBRA International, EB Research Partnership, Fritz Thyssen Stiftung, German Research Foundation (funding of research projects), and 3R Pharma Consulting and Midas Pharma GmbH (consultation for losartan new drug formulation).

High cost of wound dressings for epidermolysis bullosa highlighted

Article Type

Wed, 02/05/2020 - 13:39

– More than £2.8 million (almost $3.7 million) was spent every year on wound dressings and bandages for treatment in a group of 60 people with recessive dystrophic epidermolysis bullosa (RDEB), according to a report at the EB World Congress, organized by the Dystrophic Epidermolysis Bullosa Association (DEBRA).

Dr. Jemima Mellerio, St John’s Institute of Dermatology, at Guy’s & St. Thomas’ NHS Foundation Trust, London
Dr. Jemima Mellerio

Results from the Prospective Epidermolysis Bullosa Longitudinal Evaluation Study (PEBLES), which is looking at the natural history of RDEB, showed that wound dressing and bandage costs were highest for study participants with the generalized severe (RDEB-GS) subtype, at just over £85,156 (about $112,450) per patient annually. Respective yearly costs for the generalized intermediate (RDEB-GI) and inversa (RDEB-INV) subtypes were £10,112 (about $13,350) and £1,699 (about $2,240) per patient.

Looking at the costs associated with EB is important, said one of the lead investigators for PEBLES, Jemima Mellerio, MD, FRCP, consultant dermatologist at St John’s Institute of Dermatology, at Guy’s & St. Thomas’ NHS Foundation Trust, London.

“If we are going to justify the kind of expenditure [associated with new treatments], we need to know that what we are treating is already a significant burden on our health care systems,” Dr. Mellerio said.

PEBLES is an ongoing London-based registry study that is enrolling patients with all subtypes of RDEB. Data are collected via a tablet device and include demographic data, information on clinical features, results of skin biopsies and genetic tests, and laboratory findings, as well as objective disease severity and subjective patient-orientated outcome scores.

So far, 60 patients – 49 adults and 11 children – have been enrolled in PEBLES since November 2014: 26 with RDEB-GS, 23 with RDEB-GI, 9 with RDEB-INV, and 2 with the pruriginosa RDEB subtype (RDEB-PR).

Most of the participants (71%) changed all their wound dressings at one time, patching up when required. Fourteen of 49 participants had paid people to help them change their dressings and when the total cost of combined wound dressings and paid care was taken into consideration, the mean annual cost per patient was around £2,500 (about $3,300) for RDEB-INV, £10,375 (about $13,700) per patient for RDEB-GS, and a staggering £98,000 (about $129,000) per patient for RDEB-GS. The total annual cost of dressings and associated care was an estimated £3,184,229 (about $4.2 million).

In addition to data on the cost of wound dressings, data on itch and pain and quality of life were presented at the EB World Congress and discussed by Dr. Mellerio.

A total of 42 participants older than 8 years of age had itch measured via the Leuven Itch Scale, she reported, noting that itch was a consistent symptom across all subtypes of RDEB. Itch is important as it not only causes problems with skin lesions and healing, but also significantly affects sleep and has a negative impact on patients’ mood, she emphasized.

Despite experiencing itch, more than half (58%) of participants were not using any kind of treatment for itch. This “likely reflects the lack of effectiveness of current medication for this debilitating symptom,” Dr. Mellerio and associates noted in one of their poster presentations of PEBLES data.

When treatment was used for itch, it consisted mainly of antihistamines (19% of patients), emollients (19%), or a combination of both (4%). However, treatment was generally “not very good,” with a satisfaction score of just 5 on a scale of 10, Dr. Mellerio pointed out. Participants “reported frustration with the lack of effective treatment for itch,” she said.

Itch was associated with disturbed sleep 1-3 nights per week in 20%-40% of participants, and every night in 20%-30%.

Pain was found to be a significant problem, with a median level of background pain scored as 4 on a 10-cm visual analog scale and a higher level (6) when associated with dressing changes.

Data on how RDEB affected quality of life were reported for 39 adults completing the 17-item Quality of Life in EB Questionnaire (QOLEB) and eight children who were able to complete the Pediatric Quality of Life Inventory (PedsQL) with the aid of their parents.

Dr. Mellerio reported that adults with RDEB-GS had an overall QOLEB score of 24 out of 50, an indication that their condition had a severe impact on their quality of life. The effect on quality of life was greater in terms of their physical functioning than emotional well-being, with respective scores of 19 out of 36, and 5 out of a possible 15. Less impact on quality of life was reported by participants with other RDEB subtypes.

PedsQL scores for the children indicated there might be a lesser effect of physical functioning on quality of life but a greater effect of emotional well-being on quality of life, but the numbers were small. “Interestingly, parents tended to rate their children’s impact on quality of life much higher than the children themselves,” Dr. Mellerio said.

The point of PEBLES is to start to understand the natural history of RDEB and to identify endpoints that might help in clinical trials of potential new treatments. Discussing the next steps for PEBLES, Dr. Mellerio said the aim was to recruit more pediatric patients and look at other data sets, such as bone health. The PEBLES team also hopes to extend recruitment to include other United Kingdom, and ultimately international, EB centers and, perhaps eventually to start to include other types of EB, such as EB simplex.

PEBLES is funded by DEBRA UK. Dr. Mellerio is a PEBLES investigator but had no conflicts of interest to disclose.

– More than £2.8 million (almost $3.7 million) was spent every year on wound dressings and bandages for treatment in a group of 60 people with recessive dystrophic epidermolysis bullosa (RDEB), according to a report at the EB World Congress, organized by the Dystrophic Epidermolysis Bullosa Association (DEBRA).

Results from the Prospective Epidermolysis Bullosa Longitudinal Evaluation Study (PEBLES), which is looking at the natural history of RDEB, showed that wound dressing and bandage costs were highest for study participants with the generalized severe (RDEB-GS) subtype, at just over £85,156 (about $112,450) per patient annually. Respective yearly costs for the generalized intermediate (RDEB-GI) and inversa (RDEB-INV) subtypes were £10,112 (about $13,350) and £1,699 (about $2,240) per patient.

Looking at the costs associated with EB is important, said one of the lead investigators for PEBLES, Jemima Mellerio, MD, FRCP, consultant dermatologist at St John’s Institute of Dermatology, at Guy’s & St. Thomas’ NHS Foundation Trust, London.

“If we are going to justify the kind of expenditure [associated with new treatments], we need to know that what we are treating is already a significant burden on our health care systems,” Dr. Mellerio said.

PEBLES is an ongoing London-based registry study that is enrolling patients with all subtypes of RDEB. Data are collected via a tablet device and include demographic data, information on clinical features, results of skin biopsies and genetic tests, and laboratory findings, as well as objective disease severity and subjective patient-orientated outcome scores.

So far, 60 patients – 49 adults and 11 children – have been enrolled in PEBLES since November 2014: 26 with RDEB-GS, 23 with RDEB-GI, 9 with RDEB-INV, and 2 with the pruriginosa RDEB subtype (RDEB-PR).

Most of the participants (71%) changed all their wound dressings at one time, patching up when required. Fourteen of 49 participants had paid people to help them change their dressings and when the total cost of combined wound dressings and paid care was taken into consideration, the mean annual cost per patient was around £2,500 (about $3,300) for RDEB-INV, £10,375 (about $13,700) per patient for RDEB-GS, and a staggering £98,000 (about $129,000) per patient for RDEB-GS. The total annual cost of dressings and associated care was an estimated £3,184,229 (about $4.2 million).

In addition to data on the cost of wound dressings, data on itch and pain and quality of life were presented at the EB World Congress and discussed by Dr. Mellerio.

A total of 42 participants older than 8 years of age had itch measured via the Leuven Itch Scale, she reported, noting that itch was a consistent symptom across all subtypes of RDEB. Itch is important as it not only causes problems with skin lesions and healing, but also significantly affects sleep and has a negative impact on patients’ mood, she emphasized.
