Vobarilizumab (ALX-0061) at the 2017 ACR Annual Meeting in San Diego


As vobarilizumab has caught my interest a while ago [1], I had already looked closer at this anti-IL6 receptor (IL-6R) nanobody® at the 2017 EULAR Annual Meeting in Madrid [2] and concluded: “The data is interesting and promising, but the big question remains: will there be a phase 3 study?”

There had been one study on vobarilizumab at the 2017 ACR Annual Meeting in San Diego, just one.

M. Rinaldi and colleagues presented [3]: “Assessment of Dose Dependent Effects of Vobarilizumab, an Anti-IL6 Receptor (IL-6R) Nanobody®, on Systemic Biomarkers in Patients with Moderate-to-Severe Rheumatoid Arthritis (RA): Results of Two Phase 2b Studies”. The authors looked at the effect of vobarilizumab and tocilizumab on biomarkers like CRP, ESR, soluble IL-6 receptor (sIL-6R), matrix metalloproteinase-3, and chemokine ligand 13 (CXCL13). The authors concluded: “The observed dose dependent PD [pharmacodynamics] biomarker responses and effects on cartilage degradation and joint inflammation biomarkers further support the strong potential for disease modifying activity of vobarilizumab in RA [rheumatoid arthritis].”

A bit disappointing, isn’t it? Not the results, but the slowing down of research and commitment. I’ve just looked, if there is a phase 3 study [4], but didn’t find one. Abbvie seems to kindle a fire so light, that it might be blown out soon.
