Clinical Trial Summary

HSCT has been implemented in (inter)national treatment guidelines for diffuse cutaneous systemic sclerosis (dcSSc) and is offered in clinical care and reimbursed by national health insurance in several European countries. However, data and specific guidelines on the best timing of HSCT in the course of dcSSc are lacking. In particular, it is unclear whether HSCT should be positioned as upfront therapy or as rescue treatment for patients not responding to conventional immunosuppressive therapy.

This multicentre, randomized, open label trial aims to compare two treatment strategies used in usual care: upfront autologous HSCT versus usual care with (intravenous (i.v.) cyclophosphamide (CYC) pulse therapy followed by mycophenolate mofetil (MMF) and HSCT as rescue option).

Description:

Rationale: This multicentre, randomized, open label trial aims to compare two treatment strategies used in usual care: upfront autologous HSCT versus usual care with (intravenous (i.v.) cyclophosphamide (CYC) pulse thera-py followed by mycophenolate mofetil (MMF) and HSCT as rescue option). HSCT has been implemented in (inter)national treatment guidelines for diffuse cutaneous systemic sclerosis (dcSSc) and is offered in clinical care and reimbursed by national health insurance in several European countries. However, data and specific guidelines on the best timing of HSCT in the course of dcSSc are lacking.

In particular, it is unclear whether HSCT should be positioned as upfront therapy or as rescue treatment for patients not responding to conventional im-munosuppressive therapy. Given the risks and costs associated with HSCT, it may be preferable to evaluate the patient's response to immunosuppressive therapy before proceeding to HSCT. Considering HSCT as a rescue treatment could significantly delay the need for a potentially harmful treatment and may be an efficient approach from a health economic perspective as HSCT is a highly specialized, resource intensive and expensive medical procedure. On the other hand, in the time frame needed to evaluate the effect of immunosuppressive therapy, pulmonary and cardiac involvement may develop, negatively influencing a patient's prognosis and possibly leading to a contra-indication for HSCT. We hypothesize that upfront HSCT results in less toxicity and medical costs in the long run. Therefore, we propose a multicentre randomized open label trial in chemotherapy naive patients with early dcSSc.

Objective: To determine the optimal treatment strategy in early dcSSc: the effect of HSCT as upfront therapy compared with that of immunosuppressive medication in early dcSSc, with respect to survival and prevention of major organ failure (referred to as 'event-free survival' which is considered as primary endpoint), safety and the impact on skin thickening, visceral involvement, functional status, and quality of life

Secondary goals are to evaluate (in both treatment arms) whether disease activity correlates with immunological parameters, including immunopathology of skin, immune reconstitution, and autoantibodies. We will also de-termine the cost-effectiveness of HSCT as first line treatment versus usual care and try to identify factors associated with response to treatment.

Study design: This investigation is an international multicentre, prospective, randomized, open label trial com-paring two treatment strategies used in regular care: upfront autologous HSCT versus immunosuppressive thera-py with i.v. CYC pulse therapy followed by MMF and HSCT as rescue option.

Study population: Patients aged between 18 - 65 years with an established diagnosis of dcSSc according to the ACR/EULAR criteria. Patients disease duration (non-Raynaud's symptoms) should be ≤ 3 years and mRSS ≥ 15 (diffuse skin pattern) and /or clinically significant organ involvement (heart and lung involvement).

Intervention: One group (A) receives upfront autologous HSCT and the other group (B) receives 12 monthly i.v. pulses CYC (750 mg/m2), followed by at least 12 months of oral MMF (max 3 grams daily) at one year after start of treatment. Rescue therapy may be considered in both arms in case of insufficient response or clinically relevant flare, but preferably not within the first 3 months after randomisation. For patients from Arm A methotrexate, mycophenolate mofetil or mycophenolic acid, or rituximab can be (re)instituted, according to local preference. Based on earlier studies, the clinical benefits of i.v. pulse cyclophosphamide may take between 6-12 months. Therefore it is recommended to then switch patients from arm B to HSCT only in case of rapidly progressive disease, which is arbitrarily defined as ≥30% increase in mRSS or ≥20% relative decline in FVC, TLC, or DLCO predicted.

Main study parameters/endpoints: Global Rank Composit score at 24 months follow-up.

Secondary efficacy endpoints: Event-free survival after randomisation/treatment, overall survival (OS), progression-free survival, number of participants that need rescue therapy (i.e. the alternative treatment) due to treatment failure. Treatment related mortality, treatment toxicity, and changes in mRSS, FVC, TLC and DLCO, nailfold microscopy, immunological markers in skin and blood, cardiac MR and 18FDG-PET. The CRISS at 12 months. Safety and tolerability outcomes according to CTC-criteria (CTCAE v5.0). Patient reported outcomes at 12 and 24 months include: Quality of life (EQ-5D), SHAQ, Gastrointestinal complaints (UCLA SCTC GIT 2.0), sexual functioning.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Global Rank Composite Score (GRCS)	The GRCS is an analytic tool that accounts for multiple disease manifestations simultaneously.; For this endpoint, seveal endpoints will be used: death, event-free survival (EFS), forced vital capacity (FVC), Health Assessment Questionnaire - Disability Index (HAQ-DI), and Modified Rodnan Skin Score (mRSS).; Participants alive ranked higher than those who died; those who survived event-free ranked higher than EFS failures. EFS failure included death, respiratory failure (decrease from baseline of >30% in DLCO % predicted or >20% in FVC % predicted ), renal failure (chronic dialysis > 6 month or renal transplant), or cardiac failure (clinical congestive heart failure or left ventricular ejection fraction <30%). The lowest 3 GRCS components are ordinal; improvement, stability, or worsening from baseline (±10% change in FVC % predicted, ±0.4 change in HAQ-DI, ±25% change in mRSS).	24 months
Secondary	Number of patients who survive without disease progression (Progression-free survival)	Defined as the time in days since the day of randomisation until any of the following relative changes from base-line has been documented: death,; = 10% drop in (F)VC predicted and/or = 15% drop in DLCO predicted,; = 15% drop in LVEF by echo or cardiac MR,; = 15% drop in body weight,; = 30% drop in creatinine clearance,; = 30% increase in skin score,; = 0.5 increase in SHAQ.	24 months
Secondary	Number of patients who die due to complications related to the treatment (Treatment related mortality)	Defined as any death during the study period following randomisation that cannot be attributed to progression of the disease according to the consensus opinion of the DSMB.	24 months
Secondary	Number of patient alive after 24 months (Overall mortality)	Any death, regardless of relationship to treatment, between randomization and 24 months post-randomization	24 months
Secondary	Number of CTCAE toxicity advserse events	Number of CTCAE v5.0 toxicity advserse events =/> grade 3 that occur in consecutive 3-month periods following randomisation until 24 months follow-up.	24 months
Secondary	The area under the curve (AUC) of the CRISS over time	The American College of Rheumatology Composite Response Index in Diffuse Cutaneous Systemic Sclerosis (ACR CRISS) was developed using expert consensus and data driven approaches for use in clinical trials (Khanna et al, 2016).; The exponential algorithm determines the predicted probability of improvement from baseline, incorporating change in the mRSS, FVC percent predicted, physician and patient global assessments, and HAQ-DI. The outcome is a continuous variable between 0.0 and 1.0 (0 - 100%). A higher score indicates greater improvement. Subjects are not considered improved (ACR CRISS score = 0) if they develop new: 1) renal crisis; 2) decline in FVC% predicted by 15% (relative) from baseline and confirmed after 1 month; or 3) left ventricular failure (systolic ejection fraction < 45%); or 4) new pulmonary artery hypertension on right heart catheterization requiring treatment.	24 months
Secondary	Changes in skin involvement (modified Rodnan Skin Score)	Modified Rodnan Skin Score (mRSS) The MRSS is a validated physical examination method for estimating skin induration. It is correlated with biopsy measures of skin thickness and reflects prognosis and visceral involvement, especially in early disease2, 4. It is scored on a 0 (normal) to 3+ (severe induration) ordinal scales over 17 body areas, with a maximum score of 51 and is used to categorize severity of SSc. Minimally clinically significant difference in MRSS is 3-5 points (Amjadi et al., American College of Rheumatology; Aug 2009; 2493-2494) It has been extensively used as primary/ secondary outcome in RCT with Scleroderma. This will be collected at every study visit.	24 months
Secondary	Changes in cardiac function(Left Ventricular Ejection Fraction)	LVEF is measured by cardiac echo and at baseline and 12 months with cardiac MRI.	12 and 24 months
Secondary	Changes in pulmonary function	Diffusion in liters of carbon monoxide (DLCO) is a measure of lung function. Predicted values for DLCO were computed using the Crapo Morris equations and adjusted per the Cotes formula for anemia, if a participant's hemoglobin was <13 or >17 gm/dL, and altitude (Calgary site only). Forced Vital Capacity (FVC) is the amount of air that can be forcibly exhaled after a full breath and is a measure of lung function. Predicted FVC was based on institutional standards.	12 and 24 months
Secondary	Changes in health related quality of life EQ-5D-5L index	HR-QoL will be assessed using the validated EuroQol (EQ-5D-5L), the calculated index ranges from 0 (worse HR-QoL) to 1 (best HR-QoL).	24 months
Secondary	Changes in nailfold capillaroscopy	Nailfold capillaroscopy (NFS) will be obtained by the local capillaroscopist pre- and post-ASCT (at baseline, at 6, 12 24 months and yearly after). The evaluation of the images will be done centrally. The NFS-findings will be described standardly according to the consensus of the EULAR study group on microcirculation in rheumatic diseases. As such, the images will be evaluated in a quantitative (density, di-mension, morphology and presence of haemorrhages) and a qualitative way (normal, aspecific abnormalities, early/active/late scleroderma pattern). As we will analyse 16 NFS-images per subject, an overall qualitative as-sessment per subject will be assigned, based on the most prevalent pattern per subject.	12 and 24 months
Secondary	Changes in 18F FDG-PET scan from the thorax	Validation of semi-quantitative analysis method with respiratory gated and non-gated 18F FDG-PET prospec-tively and comparison of 18F FDG-PET with routine HR-CT thorax, pulmonary lung function and clinical symptoms, will be done at baseline and at 12 months follow-up.	12 months
Secondary	Changes in gastrointestinal complaints (UCLA SCTC GIT 2.0)	The UCLA SCTC GIT 2.0 is a standardized set of outcome measures developed through literature review, patient focus groups and cognitive debriefing among patients with a variety of gastrointestinal disorders including irritable bowel syndrome, inflammatory bowel disease, other common gastrointestinal disorders, SSc, and a census-based US general population control sample (Khanna et al, 2009). The scale consists of eight domains relating to gastroesophageal reflux (13 items), disrupted swallowing (7 items), diarrhea (5 items), bowel incontinence/soilage (4 items), nausea and vomiting (4 items), constipation (9 items), belly pain (6 items), and gas/bloat/flatulence (12 items). The scales correlated significantly with both generic and disease-targeted legacy instruments, and demonstrate evidence of reliability.	12 and 24 months
Secondary	Changes in several subsets of the immune system	We will evaluate antibody repertoire pre- and post-treatment at dedicated timepoints and assess correlations to clinical disease course characteristics. Also, B cells will be characterized in terms of frequency, phenotype and functional capacities before and after treatment. Additionally, transcriptomics analysis on the immune cell (sub-)populations isolated will be done.	12 months
Secondary	Changes in self-assessed skin thickness (PASTUL_)	Patients will assess their skin thickness using the validate PASTUL questionnaire every 3 months.	60 months
Secondary	Inflammatory and fibrotic characteristics and changes of the skin and composition of the microbiome of the skin	Skin biopsies from affected skin will be used to investigate the inflammatory and fibrotic changes and the skin microbiome. Before taking the skin biopsies the skin will be anesthetized with lidocaine 1%. The biopsy used for analysis of the inflammatory and fibrotic characteristics, using immunohistochemistry, will be frozen in liquid nitrogen. 6S rRNA gene sequencing will be done to obtain the microbial profiles of the skin biopsies.	12 months
Secondary	Changes in sexual functioning	We will use the validated IIEF-5 and SFQ-28	12 and 24 months
Secondary	Changes in daily functioning	SHAQ-DI The SHAQ-DI is a disease-targeted, musculoskeletal-targeted measure intended for assessing functional ability in scleroderma. It is a self-administered 20-question instrument that assesses a patient's level of functional ability and includes questions that involve both upper and lower extremities. The SHAQ-DI score ranges from 0 (no disability) to 3 (severe disability). It has a 7 day recall period and has been extensively used in SSc. Five visual analog scales are included in the scleroderma-HAQ assessing burden of digital ulcers, Raynaud's, gastrointestinal involvement, breathing, and overall disease.	12 and 24 months
Secondary	Changes in ability to work, measured by the customized Productivity Cost Questionnaire (iPCQ)	The customized iPCQ is a selection of 5 questions derived from the full iPCQ	12 and 24 months
Secondary	Changes in fatigue measured with the FACIT questionnaire	The FACIT questionnaire is a validated questionnaire for evaluating fatigue	12 and 24 months
Secondary	Changes in handmobility	assessment done using the mHAMIS	24 months
Secondary	Number of patients who survive without major events (event free survival)	Event-free survival is defined as the time in days from the day of randomisation until the occurrence of death due to any cause or the development of persistent major organ failure (heart, lung, kidney) defined as follows: Heart: left ventricular ejection fraction < 30% by cardiac MR (or cardiac echo); Lungs: respiratory failure = resting arterial oxygen tension (PaO2) < 8 kPa (< 60 mmHg) and/or resting arterial carbon dioxide tension (PaCO2) > 6.7 kPa (> 50 mmHg) without oxygen supply; Kidney: need for renal replacement therapy	24 months
