The rate of decline of FVC (mL/year) was greatest in the placebo arm not on background MMF at baseline (−119.3), and lowest in the nintedanib arm taking MMF at baseline (−40.2), and similar in the nintedanib alone arm (−63.9) and placebo arm on background MMF at baseline (−66.5). In contrast with MMF and CYC [12,41], treatment with nintedanib did not lead to an improvement in self-reported dyspnea as measured by the St. George’s Respiratory Questionnaire (SGRQ), nor mRSS [25]. It is unclear why patients randomized to nintedanib did not experience an improvement in the SGRQ relative to placebo; however, it may be because responses to this questionnaire are influenced by extra-pulmonary manifestations of SSc not targeted by nintedanib (e.g. In terms of safety, patients on combination therapy (MMF + nintedanib) appeared to have a similar adverse event profile compared with patients on nintedanib alone; however, the majority of patients on nintedanib (76%) reported diarrhea (compared with 32% in the placebo arm), and this should be taken into consideration, particularly when treating patients who have co-morbid SSc-related lower gastrointestinal tract involvement. Although it is difficult to draw meaningful conclusions about the benefits of upfront combination therapy (MMF + nintedanib) for SSc-ILD since patients were not randomized to MMF in the SENSCIS trial, the results support the hypothesis that using nintedanib as add-on therapy to MMF may be advantageous from a lung function standpoint. To this end, SLS III (NCT03221257) was conceived and designed to test the hypothesis that combining an anti-fibrotic therapy (e.g.

On-demand therapy with phosphodiesterase inhibitors (i.e. sildenafil) for the treatment of primary or secondary RP was recently shown not to have clinically relevant efficacy, given the significant heterogeneity in patient responses [48]. Few studies have focused on chew sildenafil the prevention of RP-associated ulcers. In the past decade, these areas of study have become areas of increasing interest (Table 4). The specific roles of phosphodiesterase inhibitors in healing RP-associated digital ulcers in SSc continues to be an active area of investigation, as this class of medications improves digital blood flow, and has been shown to have significant efficacy in secondary Raynaud’s [49,50].

The SEDUCE study group recently evaluated the effects of sildenafil on ischemic digital ulcer healing in SSc in a randomized placebo-controlled trial [51]. Eighty-three patients with a total of 192 digital ulcers were included in the intention-to-treat analysis (89 in the sildenafil group, 103 in the placebo group), however the primary endpoint was not reached. In order to expand therapeutic options for the treatment of SSc-related RP attacks, tadalafil was studied in a prospective double-blind placebo-controlled crossover study. Patients were randomized to receive a fixed dose of tadalafil at 20 mg daily or placebo for a 4 week period, and the RP condition score, frequency of RP episodes, and duration of RP episodes between treatment groups was compared. While tadalafil was well-tolerated, there was no significant difference in treatment response between the tadalafil arm and the placebo arm [52].
2.3. Raynaud phenomenon
However, a subsequent study examined the benefits of tadalafil as an add-on therapy for the healing and prevention of digital ulcers. This double-blind, randomized, cross-over trial evaluated the efficacy of tadalafil as add-on therapy in patients with treatment-resistant RP. Patients with SSc and MCTD who were on vasodilators, but still having 4 or more episodes of RP attacks per week were included and randomized to receive either tadalafil 20 mg per day or placebo. Significant improvements from baseline were observed in several outcome measures during tadalafil therapy compared to placebo, including mean daily frequency of RP episodes, mean daily duration of RP, and mean daily RP condition score. In the tadalafil group, all 24 digital lesions healed compared to only 3 of 13 in the placebo group, and only one new ulcer was reported during tadalafil therapy compared to 13 in patients on placebo therapy [53]. pirfenidone) with a cytotoxic, immunosuppressive agent (e.g. mycophenolate) upfront may lead to an improved and faster treatment response compared with using an immunosuppressive agent alone. In SLS III, patients with SSc-ILD who are treatment naïve or early in their course of treatment with MMF (treatment with MMF for ≤6 months prior to enrollment) are randomized to either treatment with MMF alone or treatment with MMF plus pirfenidone for 18 months. In the prior open-label study phase II study on pirfenidone for SSc, MMF was combined with pirfenidone in 63.5% of patients with good tolerability [24]. The monoclonal antibody against the sildenafil pink pill interleukin (IL)-6 receptor, tocilizumab, may play a role in the treatment of ILD in SSc, particularly in patients with early dcSSc with inflammatory features. Two RCTs have investigated the safety and efficacy of tocilizumab in patients with early dSSc with elevated acute phase reactant proteins, and while the primary outcome for these studies was mRSS, the FVC was a key secondary endpoint [18,42]. In the phase II faSScinate trial, fewer patients in the tocilizumab arm experienced a decline in FVC at 48 weeks than in the placebo group (p = 0.0373) [42]. Furthermore, the FVC treatment effect appeared to be sustained in the open-label extension period [18]. The phase III trial of tocilizumab for SSc did not meet the primary endpoint of mRSS [43]. As with cutaneous sclerosis treatment, rituximab is frequently used to treat SSc patients with progressive ILD resistant to CYC and MMF. Evidence for using rituximab in SSc-ILD is largely based on observational studies [27–30] and one small RCT of short duration, which demonstrated an improvement in lung function over 6 months in patients randomized to rituximab versus CYC [26]. In addition, a nested case-control analysis of the EUSTAR cohort found that the SSc-ILD patients (N = 9) treated with rituximab experienced stability in the FVC; whereas the matched-control patients experienced a significant decline in FVC over a median of 6 months [29]. To date, only one small RCT has been published on rituximab for SSc-ILD, and this study found that treatment with rituximab was associated with a significant improvement in lung function compared with placebo [44]. In this study, the majority of the rituximab-treated patients also experienced a reduction in ground glass opacities (but not reticulations) on HRCT at 18 months (based on visual assessment) [44]. A larger double-blind, RCT comparing IV CYC (600 mg/m2 body surface area monthly for 6 months) versus rituximab (1 g at baseline and at 2 weeks) for connective tissue disease-related ILD, including SSc-ILD, is currently underway in the UK (NCT01862926).

The primary outcome for this study is the change in FVC at 48 weeks [45] (Table 3). Approximately 90–95% of patients with SSc have Raynaud phenomenon (RP), and it is often the presenting feature of SSc. It is characterized by peripheral vasospasm that leads to a transient discoloration (erythema, cyanosis, and/or pallor) and/or numbness in the digits immediately following specific triggers, such as exposure to cold temperatures, relative changes in the temperature of the surrounding environment, and/or exposure to stress. The complications of RP are particularly severe in SSc, as the vasospasm compounds the already reduced blood flow in vessels affected by SSc vasculopathy [46]. Up to about 50% of patients with SSc are affected by RP may experience ischemic complications such as digital ulcers, pits, or gangrene [47]. This subset of patients requires more aggressive therapy with medication to prevent the loss of digital tissue. Recent studies have focused on determining whether specific drugs are more effective in preventing or healing digital ulcers, as some medications are known to be more effective for one than the other. The current standard of care for the management of patients experiencing RP-related digital ischemia involves minimizing environmental triggers and initiating medications that maximize peripheral blood flow (e.g. On-demand therapy with phosphodiesterase inhibitors (i.e. sildenafil) for the treatment of primary or secondary RP was recently shown not to have clinically relevant efficacy, given the significant heterogeneity in patient responses [48].

Article highlights.
Collectively, these data suggest that phosphodiesterase-inhibitors play an important role in the healing and prevention of digital ulcers in sildenafil spray SSc-related RP. Prostacyclins and prostaglandins continue to serve as key therapies used to treat challenging cases of RP in the context of SSc. Iloprost, for example, serves as a standard treatment of existing digital ulcers [54–56]. It is currently indicated for patients with severe disabling Raynaud’s unresponsive to other therapies for the prevention of ischemic pain, peripheral ulcers, and necrosis of the digits to prevent amputation. It may be administered by one of three schedules: (a) 3-day schedule as an inpatient for RP/SSc; (b) 5-day schedule as an outpatient for RP/SSc; or (c) continuous infusion for the treatment of patient with active or extensive digital ulcers, severe digital ischemia, or for patients who cannot tolerate higher rates of the infusion. In the tadalafil group, all 24 digital lesions healed compared to only 3 of 13 in the placebo group, and only one new ulcer was reported during tadalafil therapy compared to 13 in patients on placebo therapy [53].
