Comparative efficacy of cemiplimab versus other systemic treatments for advanced cutaneous squamous cell carcinoma.

Aim: To estimate the comparative efficacy of cemiplimab, a programmed cell death protein 1 inhibitor, versus EGFR inhibitors, pembrolizumab and platinum-based chemotherapy in terms of overall survival (OS) and progression-free survival. Patients & methods: We performed an indirect treatment comparison of cemiplimab and other available systemic therapies for patients with advanced cutaneous squamous cell carcinoma. Results: Cemiplimab was associated with benefits in OS (hazard ratios range: 0.07-0.52) and progression-free survival (hazard ratios range: 0.30-0.67) versus EGFR inhibitors and pembrolizumab (data from KEYNOTE-629). Cemiplimab was more efficacious versus platinum-based chemotherapy in terms of OS. Conclusion: Cemiplimab may offer improvements in survival for advanced cutaneous squamous cell carcinoma patients compared with existing systemic therapies.

Indirect Treatment Comparison of the Efficacy and Safety of Sarilumab Monotherapy in Rheumatoid Arthritis Patients with Inadequate Response to Conventional Disease-Modifying Antirheumatic Drugs.

INTRODUCTION: To evaluate the comparative efficacy and safety of subcutaneous sarilumab 200 mg monotherapy administered every 2 weeks (q2w) versus other monotherapies of biologic, targeted and conventional synthetic disease-modifying antirheumatic drugs (bDMARDs, tsDMARDs, csDMARDs) at recommended doses for treatment of rheumatoid arthritis in patients who are intolerant of or inadequate responders to csDMARDs (csDMARD-IR). METHODS: A systematic literature review and network meta-analysis (NMA) were conducted on 24-week efficacy outcomes: Health Assessment Questionnaire Disability Index (HAQ-DI) score, American College of Rheumatology (ACR) 20/50/70 criteria, and European League Against Rheumatism Disease Activity Score 28-joint count erythrocyte sedimentation rate (DAS28) < 2.6. In addition, serious infections and serious adverse events (SI/SAE) were examined at 24 weeks. RESULTS: Nine trials were selected for the NMA. Sarilumab 200 mg showed superiority versus adalimumab monotherapy on all efficacy outcomes and versus tofacitinib monotherapy on ACR20. Compared with csDMARDs, sarilumab 200 mg showed superiority on ACR 20/50/70 criteria and DAS28 < 2.6 but had similar efficacy on HAQ-DI. Efficacy of sarilumab 200 mg was similar versus certolizumab, etanercept, tofacitinib and tocilizumab 8 mg/kg monotherapy across all efficacy outcomes. SI/SAE appeared similar for sarilumab 200 mg versus all comparators. CONCLUSION: In csDMARD-IR patients, sarilumab 200 mg monotherapy has superior efficacy and similar safety versus csDMARDs, superior efficacy and similar safety versus adalimumab, and similar efficacy and safety versus bDMARDs and tsDMARDs.

Evaluation of the efficacy and safety of sarilumab combination therapy in patients with rheumatoid arthritis with inadequate response to conventional disease-modifying antirheumatic drugs or tumour necrosis factor α inhibitors: systematic literature review and network meta-analyses.

Objective: To compare efficacy and safety of subcutaneous sarilumab 200 mg and 150 mg every 2 weeks plus conventional synthetic disease-modifying antirheumatic drugs (+csDMARDs) versus other targeted DMARDs+csDMARDs and placebo+csDMARDs, in inadequate responders to csDMARDs (csDMARD-IR) or tumour necrosis factor α inhibitors (TNFi-IR). Methods: Systematic literature review and network meta-analyses (NMA) conducted on 24 week efficacy and safety outcomes: Health Assessment Questionnaire Disability Index, modified total sharp score (mTSS, including 52 weeks), American College of Rheumatology (ACR) 20/50/70, European League Against Rheumatism Disease Activity Score 28-joint count erythrocyte sedimentation rate (DAS28)<2.6; serious infections/serious adverse events (including 52 weeks). Results: 53 trials were selected for NMA. csDMARD-IR: Sarilumab 200 mg+csDMARDs and 150 mg+csDMARDs were superior versus placebo+csDMARDs on all outcomes. Against most targeted DMARDs, sarilumab 200 mg showed no statistically significant differences, except superiority to baricitinib 2 mg, tofacitinib and certolizumab on 24 week mTSS. Sarilumab 150 mg was similar to all targeted DMARDs. TNFi-IR: Sarilumab 200 mg was similar to abatacept, golimumab, tocilizumab 4 mg and 8 mg/kg intravenously and rituximab on ACR20/50/70, superior to baricitinib 2 mg on ACR50 and DAS28<2.6 and to abatacept, golimumab, tocilizumab 4 mg/kg intravenously and rituximab on DAS28<2.6. Sarilumab 150 mg was similar to targeted DMARDs but superior to baricitinib 2 mg and rituximab on DAS28<2.6 and inferior to tocilizumab 8 mg on ACR20 and DAS28<2.6. Serious adverse events, including serious infections, appeared similar for sarilumab versus comparators. Conclusions: Results suggest that in csDMARD-IR and TNFi-IR (a smaller network), sarilumab+csDMARD had superior efficacy and similar safety versus placebo+csDMARDs and at least similar efficacy and safety versus other targeted DMARDs+csDMARDs.
