Modeling to Inform Dose Selection for TOUR006, a Fully Human Anti-IL-6 Antibody, for Treatment of Thyroid Eye Disease: Effect of Gender and Liver and Kidney Function on Modeling the Optimal Dose Regimen (ATA 2024) - "The simulations for 20 mg and 50 mg q8w of SC TOUR006 predict that these doses/regimens will likely target ≥90% CRP suppression from baseline in most typical TED subjects without needing weight-based adjustment. The effects of additional parameters on dose modeling will be addressed in the presentation."

Tourmaline Bio Announces FDA Clearance of Investigational New Drug (IND) Application for TOUR006, an anti-IL-6 antibody with a differentiated profile for the treatment of thyroid eye disease (TED) (GlobeNewswire) - "Phase 2b trial of TOUR006 is expected to report top-line clinical data in the first half of 2025...Tourmaline Bio, Inc...today announced U.S. Food and Drug Administration (FDA) clearance of Tourmaline’s IND application for TOUR006....The planned Phase 2b trial of TOUR006 in TED is expected to evaluate 20mg and 50mg doses against placebo given by a subcutaneous injection every eight weeks. The approximately 81 participants planned to be enrolled (27 in each arm) will be moderate to severe TED patients who are in the active phase of disease. The primary endpoint for this trial will be proptosis response, or reduction of abnormal eye protrusion, measured at week 20."

Model-Based Meta-Analysis on the Efficacy of Biologics and Small Targeted Molecules for Crohn's Disease. (PubMed, Front Immunol) - "The most achievement in clinical remission (defined as CDAI less than 150) and clinical response (defined as the reduction in CDAI for 100 or 70) was observed in the simulation for PF-04236921 and infliximab, respectively. The most improvement in IBDQ was shown in tofacitinib. In general, tumor necrosis factor (TNF)-α inhibitors were the most effective biologics, and the highest efficacy of small targeted molecules was observed in janus kinase (JAK) inhibitors. These findings have important implications for clinical practice in CD."

[VIRTUAL] Efficacy of Biological Agents for the Management of Systemic Lupus Erythematosus: A Systematic Review and Network Meta-Analysis (CRA-AHPA 2021) - "These 20 RCTs investigated the following biologics: belimumab, anifrolumab, ustekinumab, atacicept, baricitinib, blisibimod, epratuzumab, IL-2, lupuzor, PF-04236921, rontalizumab, sifalimumab, and tabalumab... The NMA identified that belimumab, anifrolumab and ustekinumab demonstrated greater response in comparison to placebo, when measured using SRI. This systematic review identified that there was heterogeneity in the outcome measures and endpoints used. In the future, the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach will be applied to rate the quality of the evidence, and to gain insight into methodological pitfalls that could have negatively altered the results of RCTs."

Pharmacokinetics and C-Reactive Protein Modelling of Anti-IL-6 Antibody (PF-04236921) in Healthy Volunteers and Patients with Autoimmune Disease. (PubMed, Br J Clin Pharmacol) - "Integrated population PK and PK/PD models of PF-04236921 have been developed using pooled data from healthy subjects and autoimmune patients. The current model enables simulation of PF-04236921 PK and PD profiles under various dosing regimens and patient populations and should facilitate future clinical study of PF-04236921 and other anti-IL6 monoclonal antibodies."
