Brief Summary:
UVA-1 has been reported to be beneficial to skin changes in scleroderma in several case reports and a few small studies Jacobe 2020 Interpretation of these reports has been difficult based on the small numbers of subjects involved and the non-blinded non-randomized nature of the reports In a single controlled study with half-side comparison of 9 patients the investigators could not demonstrate improvement with UVA-1 in the treated hand Thomas 2007 This study was limited by a small number of patients and the long disease duration prior to treatment mean of 13 years A more recent report of a patient with scleroderma for 25 years and severe acrosclerosis that responded to 21 sessions of UVA-1 with improved mobility and functionality renews interest in this treatment modality Cuenca-Barrales 2019
In this trial patients will be randomized to have their dominant or non-dominant hand undergo 30 sessions of UVA1 therapy We will assess patients hand mobility hand function skin hardening assessed by durometer measurements skin thickness as well as patient reported outcomes to determine efficacy
This study will use a single-blind prospective randomized dominantnon-dominant hand comparator design to assess the effect of high dose 80-120 Jcm2 UVA1 therapy on hand function in scleroderma in a paired t-test design This study will be placebo-controlled with a UV-blocking gloved hand cross-over randomized clinical trial Following the initial treatment period 30 treatments patients will have the option to undergo the same high dose UVA1 treatment protocol on the untreated control hand A follow up period of 12 months following completion of UVA1 therapy will prospectively follow patients to monitor for relapse of their disease to assess the durability of the clinical response to UVA1 therapy on hand scleroderma

Detailed Description:
Systemic sclerosis SSc also called scleroderma is a rare chronic autoimmune disease that can have a wide range of cutaneous joint and internal organ involvement In the skin SSc is characterized by enhanced fibroblast activity leading to hypertrophic dermal collagen that results in thickened less flexible skin Hassani 2016 SSc is often divided into two types based on extent of cutaneous involvement diffuse SSc and limited SSc The hand is a frequent area of involvement in both subtypes of SSc Hand disability in SSc leads to a high burden on quality of life for patients as it limits both work and activities of daily living Treatment for hand sclerosis remains limited with generally progressive disease despite aggressive treatment with anti-fibrotic medications immunosuppressive agents and topical approaches Specific hand therapies include physiotherapy and injections of autologous adipose-derived stromal vascular fraction into the fingers with some success Guillaume-Jugnot 2016 Liem 2019
Ultraviolet therapy has been used in dermatology for several decades UVA-1 is a form of phototherapy that utilizes the longest wavelengths in the UV spectrum from 340-400 nm It is able to penetrate deeper in the skin than other types of phototherapy and target different types of cells including fibroblasts In sclerosing skin conditions UVA-1 appears to be superior to other forms of UV light Medium to high dose UVA-1 also appears to be superior to low dose UVA-1 for sclerosing conditions Kreuter 2006
UVA-1 has been reported to be beneficial to skin changes in SSc in several case reports and a few small studies Jacobe 2020 Interpretation of these reports has been difficult based on the small numbers of subjects involved and the non-blinded non-randomized nature of the reports In a single controlled study with half-side comparison of 9 patients the investigators could not demonstrate improvement with UVA-1 in the treated hand Thomas 2007 This study was limited by a small number of patients and the long disease duration prior to treatment mean of 13 years A more recent report of a patient with SSc for 25 years and severe acrosclerosis that responded to 21 sessions of UVA-1 with improved mobility and functionality renews interest in this treatment modality Cuenca-Barrales 2019
If UVA1 therapy can significantly improve hand involvement in SSc with regards to functionality and disability it may be a cost-effective and beneficial treatment for this patient segment with debilitating disease
Purpose and Objectives
1 To assess the efficacy of 30 sessions of ultraviolet-1 UVA1 therapy in treating hand involvement of SSc in a prospective randomized investigator-blinded intra-patient UV-blocking glove-controlled crossover clinical trial
1 To compare improvement in hand function as measured by the Hand Mobility in Scleroderma HAMIS test in the UVA1-treated hand compared to control hand gloved
2 To compare the improvement in hand function as measured by the Cochin hand functional disability scale CHFDS in the UVA1-treated hand compared to control hand gloved
3 To compare the improvement in skin hardening based on durometer measurements in the UVA1-treated hand compared to control hand gloved
4 To measure improvement in the physician measure of skin thickness on hands and fingers 0-3 scale after completion of 30 UVA1 sessions
5 To assess the duration of response after a complete 30-treatment course at 3 and12 months post treatment using the HAMIS CHFDS durometer and physician skin thickness assessment
2 Assess patient-reported outcomes before during and after treatment using Skindex-16 Michigan Hand Questionnaire MHQ PROMIS-Physical Function PROMIS-PF Hand Disability in Systemic Sclerosis - Digital UlcersHDISS-DU and Visual Analog Scale VAS
Study Design

Procedures
This is a single-blinded randomized UV-blocking glove controlled dominantnon-dominant hand cross-over study to determine the efficacy of UVA1 in the treatment of hand scleroderma Each participant will have at least one hand treated with UVA1 during the active treatment period of the study The study will be performed at the University of Utah Dermatology Department using both the University of Utah E12 Clinic space as well as the Midvalley Clinic space UVA1 lights boxes are located at both E12 and Midvalley locations Personnel involved in the study will include the PI the co-investigators and the study coordinators Approximately 27 patients will be enrolled to account for a 25 drop-out rate The number needed to treat to show a difference in the treatment vs control hands is 21 The study timeline is summarized in Table 1
Screening
For screening subjects with qualifying scleroderma involving both hands will be asked to read and sign the informed consent document They will be reminded that they are to take their time and if necessary take it home for further consideration Questions will be answered Those meeting inclusion exclusion criteria who have signed informed consent will be enrolled
After answering questions and prior to the first treatment the Principal Investigator PI will examine the entire patient and assess for the diagnosis of systemic sclerosis with bilateral hand involvement and perform the following assessments HAMIS CHFDS durometer measurements and mRSS Please see efficacy assessment section for details of HAMIS CHFDS durometer and mRSS Photographs of the hands and other affected areas will be taken The patient will be asked to identify their dominant writing hand and their answer will be noted Using a random number generator the patient will be randomized to undergo UVA1 treatment vs UV-blocking glove control on the dominant hand The non-dominant hand will receive the other modality A study coordinator will perform the randomization on the day of first treatment and the PI will be blinded to the treatment assignment
UVA1 Treatments
Blinding
A UV-blocking glove will be placed on the control hand as determined by the randomization process Subjects will wear eyewear that occludes external light
Evaluations for adverse effects will be carried out by the UVA1 operator a nurse not involved in any assessments and the blinded investigator at prescribed intervals Evaluation of UVA1 efficacy on hand scleroderma will be assessed by a trained and experienced evaluator who is blinded as to the UVA1-treated side covered not covered The efficacy evaluations will be carried out prior to treatments on days both evaluations and treatments are completed After participants have been evaluated at the 3-month post-treatment study visit the blinded evaluator will become unblinded to the UVA1-treated side for the purpose of allowing participants to receive standard of care therapy Therefore participants will be allowed to receive additional UVA-1 treatments to one or both hands in addition to any other necessary standard of care treatments after the 3-month post-treatment visit
Dosing Schedule
Prior studies with UVA1 have shown that high and medium dose protocols 40-120 Jcm2 are more effective than low dose 20-40 Jcm2 to treat sclerosing skin conditions Hassani 2016 Thus we will set the initiation dose at 50 J The hands will be positioned approximately 9 inches from the bulbs The palmar surface of the hand will be exposed for half the treatment and the dorsal surface for half the treatment If tolerating well after three treatments the dose will be increased to 60 J for three treatments and then 70 J for the remaining treatments
Patients will return to clinic two-to-three times per week for 30 treatments over a 100-day period to receive UVA1 treatments If the patient experiences redness burning pain or blistering at the treatment site treatment will be held if active symptoms persist at the time of the next scheduled treatment If the symptoms have resolved and the patient has healed by the next scheduled treatment the UVA1 energy will be reduced by 10 J of the previously delivered dose Dose escalation will then proceed by increasing the UVA1 energy after three well tolerated treatments
Evaluations
1 Efficacy evaluations will be performed at baseline after 15 UVA1 treatment sessions after 30 UVA1 treatment sessions and at 3 and 12 months after completion of all UVA1 treatments For each evaluation prior to the 12-month evaluation one of the sub-Investigators who is blinded to the treatment assignments will generate and record the HAMIS CHFDS Durometer and mRSS Hands will be photographed Patients will complete all PROM including using Skindex-16 Michigan Hand Questionnaire MHQ PROMIS-Physical Function PROMIS-PF Hand Disability in Systemic Sclerosis - Digital UlcersHDISS-DU and Visual Analog Scale VAS
The blinded evaluator will also perform safety evaluation and document study-related adverse events
1 Primary Efficacy Measure
The efficacy will be measured using the HAMIS test score to assess for improvement over time and as compared to the untreated hand The primary endpoint will be assessed after 30 UVA1 treatments The primary endpoint is improvement in HAMIS score as compared to the untreated hand after 30 UVA1 treatment sessions
2 Secondary Efficacy Measures
Secondary efficacy measures include HAMIS test score improvement from baseline in treated and untreated hands after 30 UVA1 treatment sessions as well as changes in CHFDS Durometer measures mRSS Skindex-16 MHQ PROMIS-PF and VAS scores between baseline and after 30 UVA1 treatment sessions and when applicable between treated and untreated hands Other secondary efficacy measures include change in HAMIS test scores CHFDS Durometer measures Physician assessment Skindex-16 MHQ PROMIS-PF HDISS-DU and VAS scores between completion of 30 UVA1 treatments and 3 and 12 months post-treatment in both hands as compared to baseline and after 30 UVA1 treatment sessions in each hand Secondary endpoint measures also include time to disease worsening after treatment as defined by a 3-point 10 increase in HAMIS scores post-treatment
Endpoint measure descriptions
HAMIS is a hand function test developed for adults with systemic sclerosis HAMIS consists of 9 items designed to measure all movements assessed in an ordinary range of motion ROM-measured hand test Specific items test finger flexion and extension thumb abduction pincer grip finger abductionswelling dorsal extension and volar extension of the wrist and pronation and supination Each item is graded on a 0-3 scale where 0 corresponds to normal function and 3 denotes that the individual is unable to perform the item Each hand is assessed separately The minimum score for HAMIS is 0 representing normal hand function The maximum score of HAMIS is 27 representing a high degree of dysfunction Sandqvist 2000
The CHFDS is a questionnaire with 18 questions concerning daily living activities administered by a clinician which each question scored on a scale from 0 performed without difficulty to 5 impossible to do The total score is obtained by adding the scores from all items range 0-90 with lower scores indicating normal function and higher scores indicating poor function This test was developed for rheumatoid arthritis but has been validated in scleroderma Rannaou 2007
A Durometer is an instrument for testing the hardness of various materials It has been used in scleroderma to measure the hardness of affected skin as compared to normal skin
The physician assessment on skin thickness on the hand and fingers based on the modified Rodnan skin score mRSS which is a standard outcome measure for skin disease in systemic sclerosis The score is calculated by evaluating the skin thickness at 17 different body sites Each site is graded from 0 to 3 with 0 representing normal skin and 3 representing severe skin thickness The score is calculated by adding the scores at each site to arrive at a total score ranging from 0 normal to 51 severe disease Khanna 2017 In this study we will only calculate the score for the hands and fingers Total possible score of 6 on each hand
Skindex-16 is a 16-item validated assessment for the patient to identify the impact of their skin disease on three quality of life domains symptoms emotions and physical functioning Scores are normalized to a 0-100 scale with 0 representing no impact on quality of life and 100 representing maximal impact
The Michigan Hand Questionnaire MHQ is a 37-item validated instrument exploring hand-specific outcomes across six domains overall hand function activities of daily living ADLs pain work performance aesthetics and patient satisfaction with hand function It asks questions separately about each hand allowing for comparisons between hands The raw score is converted to a 0-100 scale For pain a higher score indicates more pain but for the other five scales higher scores indicate better hand performance The score for the affected hand is obtained by selecting either the right or the left hand score
Hand Disability in Systemic Sclerosis - Digital UlcersHDISS-DU is a patient reported outcome measure developed to capture the full spectrum of symptoms and disability related to digital ulcers which are common and debilitating in scleroderma involving the hands The instrument consists of 24 items Responses are scored from 1 to 6 6 scores where 1 is yes without difficulty 2 is yes with a little difficulty 3 is yes with some difficulty 4 is yes with much difficulty 5 is nearly impossible to do and used unaffected hand only both responses were assigned the same score and 6 is impossible The eighth response option did not do this activity in the past 7 days is scored as missing The overall HDISSDU score is calculated as the mean of non-missing item scores with a missing data threshold of 12 items and ranged from a minimum score of 1 to a maximum score of 6 with increasing score corresponding to increasing disability
PROMIS Physical Function PROMIS-PF is a computer adaptive test CAT wherein initial screening questions guide the need for additional questions following an iterative algorithm For example if a patient is unable to walk 100 feet without resting an additional question about jogging 1 mile would not be asked A weighted t-score results based on national averages with 50 as the mean score 50 means higher physical function 50 means lower physical function
All PROs Skindex-16 MHQ PROMIS-PF will be collected electronically at every visit
