Effect of ruxolitinib on the oral mucosa of patients with steroid-refractory chronic Graft-versus-Host disease and oral involvement.

ABSTRACT:

Background

Chronic Graft-versus-Host Disease (cGVHD) can impact quality of life, especially in patients with oral involvement. Half of the patients with cGVHD do not respond to first-line therapy with corticosteroids and calcineurin inhibitors. Ruxolitinib is effective in steroid-refractory (SR)-cGVHD cases, but the long-term effects of ruxolitinib on the oral mucosa are unknown.

Objective(s)

This study aims to assess the effect of ruxolitinib on the oral mucosa of SR-cGVHD patients with oral involvement.

Materials and methods

An observational longitudinal patient study was conducted in 53 patients with SR-cGVHD and oral involvement who were treated with ruxolitinib. The baseline condition of the oral mucosa was compared to its condition at 4 and 12 weeks after starting ruxolitinib.

Results

The overall response was 81% (43/53), with a complete response in 53% (28/53) and partial response in 28% (15/53) after 12 weeks (p < 0.001). Men and patients concurrently using immunosuppressive therapy responded better than women (p = 0.005) and patients with ruxolitinib monotherapy (p = 0.02), respectively. At a longer follow-up (median 20 months), oral symptoms were comparable to the 12-week symptoms (p = 0.78), regardless of ruxolitinib use (p = 0.83).

Conclusion

Ruxolitinib treatment of SR-cGVHD patients with oral involvement was associated with a significant response of the oral manifestations at 12 weeks.

Clinical relevance

The oral mucosa of SR-cGVHD patients is likely to improve after 4 and 12 weeks of ruxolitinib treatment. Symptom severity at baseline does not affect the response of the oral mucosa.

Project description:Graft-versus-host disease (GVHD), especially steroid-refractory GVHD, remains a life-threatening complication after hematopoietic stem cell transplantation (HSCT). The effect of the JAK1/2 kinase inhibitor ruxolitinib on treating steroid-refractory acute GVHD has been verified by the REACH1/2 study; however, its safety and efficacy in patients with steroid-refractory chronic GVHD (SR-cGVHD) remain unclear. In this retrospective study, 70 patients received ruxolitinib as a salvage therapy for SR-cGVHD. Twenty-four weeks after ruxolitinib treatment, the overall response rate (ORR) was 74.3% (52/70), including 34 patients who achieved complete remission (CR) and 18 who achieved partial remission (PR). The main adverse event was cytopenia, which occurred in 51.4% (36/70) of patients. After ruxolitinib treatment, the percentage of CD4 cells increased from 18.20% to 23.22% (P<0.001), while the percentages of NK (CD16+CD56+) cells and regulatory T cells (CD4+CD127 ± CD25+) decreased (P<0.001, P<0.001). Among the B cell subsets, the proportion of total B cells approximately tripled from 3.69% to 11.16% (P<0.001). Moreover, we observed a significant increase in IL-10 levels after ruxolitinib treatment (P=0.025) and a remarkable decrease in levels of suppression of tumorigenicity 2 (ST2) from 229.90 ng/ml to 72.65 ng/ml. The median follow-up after the initiation of ruxolitinib treatment was 401 (6-1076) days. The estimated one-year overall survival rate of the whole group was 66.0% (54.4-77.6%, 95% CI), and the one-year overall survival rate of patients with mild and moderate cGVHD was 69.6% (57.4-81.8%, 95% CI), which was better than that of patients with severe cGVHD (31.3%, 0.0-66.2%, 95% CI) (P=0.002). Patients who achieved a CR and PR achieved better survival outcomes (84.5%, 73.9-95.1%, 95% CI) than those who showed NR to ruxolitinib treatments (16.7%, 0-34.3%, 95% CI) (P<0.001). At the final follow-up, cGVHD relapse occurred in six patients after they reduced or continued their ruxolitinib doses. Collectively, our results suggest that ruxolitinib is potentially a safe and effective treatment for SR-cGVHD.

Project description:Ruxolitinib is an important treatment for steroid refractory graft-versus-host disease (SR-GVHD). Therefore, we reported the updated results of a systematic review and meta-analysis of ruxolitinib as treatment for SR-GVHD. In addition, we wanted to compare the efficacy and safety between children and adults with SR-GVHD. Overall response rate (ORR) after ruxolitinib treatment was chosen as the primary end point. Complete response rate (CRR), infection, myelosuppression, and overall survival (OS) were chosen as secondary end points. A total of 37 studies were included in this meta-analysis, and 1,580 patients were enrolled. ORR at any time after ruxolitinib treatment was 0.77 [95% confidence interval (CI): 0.68-0.84] and 0.78 (95% CI: 0.74-0.81), respectively, for SR-aGVHD and SR-cGVHD. CRR at any time after ruxolitinib treatment was 0.49 (95% CI: 0.40-0.57) and 0.15 (95% CI: 0.10-0.23), respectively, for SR-aGVHD and SR-cGVHD. The ORRs at any time after treatment was highest in mouth SR-cGVHD, followed by skin, gut, joints and fascia, liver, eyes, esophagus, and lung SR-cGVHD. The incidence rate of infections after ruxolitinib treatment was 0.61 (95% CI: 0.45-0.76) and 0.47 (95% CI: 0.31-0.63), respectively, for SR-aGVHD and SR-cGVHD. The incidence rates of overall (grades I-IV) and severe (grades III-IV) cytopenia were 53.2% (95% CI: 16.0%-90.4%) and 31.0% (95% CI: 0.0-100.0%), respectively, for SR-aGVHD, and were 28.8% (95% CI:13.0%-44.6%) and 10.4% (95% CI: 0.0-27.9%), respectively, for SR-cGVHD. The probability rate of OS at 6 months after treatment was 63.9% (95% CI: 52.5%-75.2%) for SR-aGVHD. The probability rates of OS at 6 months, 1 year, and 2 years after treatment were 95% (95% CI: 79.5%-100.0%), 78.7% (95% CI: 67.2%-90.1%), and 75.3% (95% CI: 68.0%-82.7%), respectively, for SR-cGVHD. The ORR, CRR, infection events, and myelosuppression were all comparable between children and adults with SR-GVHD. In summary, this study suggests that ruxolitinib is an effective and safe treatment for SR-GVHD, and both children and adults with SR-GVHD could benefit from ruxolitinib treatment.

Project description:ImportanceRuxolitinib, a selective inhibitor of the Janus kinases 1/2 signaling pathway, has shown a significant response in steroid-refractory chronic graft-vs-host disease (SR-cGVHD), a major cause of morbidity and mortality in individuals who have undergone allogeneic hematopoietic stem cell transplantation (HSCT).ObjectivesTo investigate the clinical response to ruxolitinib in patients with SR-cGVHD after allogeneic HSCT and to evaluate its safety profile during the treatment course.Design, setting, and participantsThis single-center case series included 41 consecutive patients who were treated with ruxolitinib for SR-cGVHD after allogeneic HSCT between August 2017 and December 2019. Data were collected from each patient's medical record at the First Affiliated Hospital of Zhejiang University School of Medicine. Data analysis was conducted from March to May 2020.ExposureRuxolitinib.Main outcomes and measuresTreatment responses, factors associated with response, and adverse effects during ruxolitinib administration.FindingsOverall, 41 patients (median [range] age, 31 [17-56] years; 14 [34.1%] women) were treated with ruxolitinib and included in this study. A total of 15 patients (36.6%) had a complete remission, and 14 (34.1%) had a partial remission, with an overall response rate of 70.7% (29 patients; 95% CI, 56.2%-85.3%). Lung involvement (odds ratio, 0.112; 95% CI, 0.020-0.639; P = .01) and matched related donors (odds ratio, 0.149; 95% CI, 0.022-0.981; P = .048) were associated with less favorable treatment response. Major adverse events associated with ruxolitinib were cytopenias and infectious complications. The median (range) follow-up for this cohort was 14.9 (1.4-32.5) months. Prolonged survival was observed in patients with a male donor (P = .006), complete remission before transplantation (P = .02), baseline moderate cGVHD (P = .02), and skin cGVHD (P = .001).Conclusions and relevanceIn this small, single-site case series, ruxolitinib demonstrated a significant response in heavily pretreated patients with SR-cGVHD and a reasonably well-tolerated safety profile. The results add to the body of literature suggesting ruxolitinib as a promising treatment option in SR-cGVHD.
