This is a randomized, double-blind, placebo-controlled, two-treatment arm, parallel-group study designed to evaluate the effects of RO5459072 treatment on disease activity and symptoms of Sjogren's syndrome in adult participants with moderate to severe primary Sjogren's syndrome. The total duration of the study for each participant will be approximately 18 weeks (including screening).

A Randomized, Double-Blind, Placebo-Controlled, Multiple Dose, Parallel Study to Investigate the Pharmacokinetics, Pharmacodynamic Effects, Safety and Tolerability of Repeated Dosing of RO5459072 in Volunteers With Celiac Disease

A randomized, double-blind, placebo-controlled, two treatment, parallel group study to investigate the effects of RO5459072, a cathepsin S inhibitor, on the immune response to a gluten challenge in volunteers with celiac disease. Volunteers with previously diagnosed celiac disease will be randomized to receive either 100 milligrams (mg) RO5459072 or placebo twice daily with food for 28 days (Days 1 to 28).

AbstractObjectivesPrimary SS (pSS) is a chronic autoimmune disorder characterized by mucosal dryness and systemic symptoms. We tested the effects of inhibition of cathepsin S using the potent and selective inhibitor RO5459072 on disease activity and symptoms of pSS.MethodsThis was a randomized, double-blind, placebo-controlled, parallel-group, Phase IIA study to investigate the effects of RO5459072 (100 mg twice daily; 200 mg per day). Seventy-five patients with pSS were randomized 1:1 to receive either RO5459072 or placebo for 12 weeks. The primary outcome was the proportion of patients with a ≥3 point reduction from baseline in EULAR SS Disease Activity Index (ESSDAI) score. We also investigated the effects of RO5459072 on quality of life, exocrine gland function, biomarkers related to SS, and safety and tolerability.ResultsThe proportion of patients showing an improvement in ESSDAI score was not significantly different between the RO5459072 and placebo arms. No clinically meaningful treatment effects were observed in favour of RO5459072 for all secondary outcomes. Analysis of soluble biomarkers indicated target engagement between RO5459072 and cathepsin S. There were modest decreases in the number of circulating B cells and T cells in the RO5459072 group, although these did not reach significance. RO5459072 was safe and well-tolerated.ConclusionsThere was no clinically relevant improvement in ESSDAI score (primary endpoint), and no apparent benefit in favour of RO5459072 in any of the secondary clinical endpoints. Further work is needed in order to understand the mechanisms of MHC-II-mediated immune stimulation in pSS.Trial registrationClinicalTrials.gov; NCT02701985.

An open-label phase 2a study investigating the efficacy and safety of a cathepsin S inhibitor in patients with moderate-to-severe psoriasis

Around 20% of psoriasis patients have moderate-to-severe disease requiring systemic treatment with cytokine-targeting biologics.Thus, there is a need for new therapies that provide sustained long-term efficacy and safety.We propose that the absence of any therapeutic effect of RO5459072 in this trial indicates the redundancy of IL-36 dedependent proinflammatory pathways involved in psoriasis.Altogether, these highlight the challenges in targeting a single component of an inflammatory pathway involved in systemic disorders such as psoriasis.In conclusion, targeting cathepsin S-mediated IL36 activation with a highly potent and selective cathepsin S antagonist had no therapeutic effect on psoriasis.

AimsRO5459072, a cathepsin‐S inhibitor, Biopharmaceutics Classification System class 2 and P‐glycoprotein substrate, exhibited complex, nonlinear pharmacokinetics (PK) while fasted that seemed to impact both the absorption and the disposition phases. When given with food, all nonlinearities disappeared. Physiologically based PK (PBPK) modelling attributed those nonlinearities to dose‐dependent solubilisation and colonic absorption. The objective of this population PK analysis was to complement the PBPK analysis.MethodsPK profiles in 39 healthy volunteers after first oral dosing (1–600 mg) while fasted or fed in single and multiple ascending dose studies were analysed using population compartmental modelling.ResultsThe PK of RO5459072 while fed was characterized by a 1‐compartmental PK model with linear absorption and elimination. The nonlinearities while fasted were captured using dose dependent bioavailability and 2 sequential first‐order absorption phases: one following drug administration and one occurring 11 hours later and only for doses >10 mg. The bioavailability in the first absorption phase increased between 1 and 10 mg and then decreased with dose, in agreement with in vitro dissolution and solubility studies. The remaining fraction of doses to be absorbed by the second absorption phase was found to have a bioavailability similar to that in the first absorption phase.ConclusionThe population PK model supported that dissolution‐ and solubility‐limited absorption from the proximal and distal intestine alone explains the nonlinear PK of RO5459072 in fasted state and the linear PK in fed state. This work, together with the PBPK analysis, raised our confidence in the understanding of this complex PK.
