Question: Which interleukin is blocked by Siltuximab?

Context:
This review also summarizes the biologics targeting either IL-6 or the IL-6 receptor, including tocilizumab, sarilumab, sirukumab, olokizumab, clazakizumab, and siltuximab. 
Siltuximab, a chimeric monoclonal antibody with high affinity and specificity for interleukin-6, has been shown to enhance anti-multiple myeloma activity of bortezomib and corticosteroid in vitro.
A phase 2, randomized, double-blind, placebo-controlled study of siltuximab (anti-IL-6 mAb) and bortezomib versus bortezomib alone in patients with relapsed or refractory multiple myeloma.
We compared the safety and efficacy of siltuximab (S), an anti-interleukin-6 chimeric monoclonal antibody, plus bortezomib (B) with placebo (plc) + B in patients with relapsed/refractory multiple myeloma in a randomized phase 2 study. 
Currently, there are more effective therapeutic alternatives in multicentric Castleman disease: treatment with monotherapy of rituximab or in combination therapy with immunomodulatory drugs (thalidomide or lenalidomide, treatment with anti-IL-6 (siltuximab) or against its receptor (tocilizumab). 
PURPOSE: Siltuximab is a monoclonal antibody that binds to interleukin (IL)-6 with high affinity and specificity; C-reactive protein (CRP) is an acute-phase protein induced by IL-6. 
Blockade of interleukin-6 signalling with siltuximab enhances melphalan cytotoxicity in preclinical models of multiple myeloma.
Antitumor efficacy of the anti-interleukin-6 (IL-6) antibody siltuximab in mouse xenograft models of lung cancer.

To study the effects of siltuximab on the interleukin-6 (IL-6)/signal transducer and activator of transcription 3 (Stat3) signaling pathway in ovarian epithelial carcinoma.
These results demonstrated that siltuximab effectively block the IL-6 signaling pathways,
These results show that siltuximab effectively block the IL-6 signaling pathways and IL-6-induced gene expression.
The IL6 regulation of IRF9 was confirmed at mRNA and protein levels by quantitative real-time PCR and western blot respectively in both cell lines and could be blocked by the anti-IL6 antibody Siltuximab.
 Siltuximab is a chimeric, anti-interleukin-6 monoclonal antibody with potential therapeutic benefit in castration-resistant prostate cancer (CRPC) patients. We assessed the safety and tolerability of siltuximab in combination with docetaxel, the pharmacokinetics of docetaxel alone and with siltuximab, and the efficacy and pharmacodynamics of siltuximab plus docetaxel.
These results demonstrated that siltuximab effectively block the IL-6 signaling pathways, which.

Treatment of ovarian cancer cells with siltuximab reduced constitutive cytokine and chemokine production and also inhibited IL-6 signaling, tumor growth, the tumor-associated macrophage infiltrate and angiogenesis in IL-6-producing intraperitoneal ovarian cancer xenografts.

Answer: Siltuximab is a monoclonal antibody that binds to interleukin-6 with high affinity and specificity.
Exact answer: interleukin-6
