What is the purpose of this trial?

This trial tests risankizumab, administered through an on-body injector, to study its absorption and utilization in the body. It aims to understand the differences between two production methods of the treatment. The trial seeks healthy adults who are generally fit, with a body weight between 40 kg and 100 kg, and a BMI (a measure of body fat based on height and weight) between 18 and 32. Participants should be in good health and must not have used similar treatments in the past year. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new treatment.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. However, since the study is for healthy participants, it's possible that you may not be on any regular medications.

Is there any evidence suggesting that risankizumab is likely to be safe for humans?

Research has shown that risankizumab is generally safe for use. In long-term studies, most participants reported little to no impact on their daily activities, indicating that serious side effects are rare. Another study found only minor side effects and no major safety issues with long-term use, suggesting the medication's safety. Although this study is in its early stages and involves healthy adults, existing evidence from other conditions supports the safety of risankizumab. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Risankizumab is unique because it uses a monoclonal antibody to specifically target and block a protein called IL-23, which plays a key role in inflammatory processes. Unlike traditional treatments for autoimmune conditions, which might broadly suppress the immune system, Risankizumab focuses on this specific pathway, potentially reducing side effects and increasing effectiveness. Researchers are especially excited about the new delivery method being tested, the On-Body Injector (OBI), which could improve patient convenience and adherence compared to conventional injection methods.

What evidence suggests that this trial's treatments could be effective?

Research has shown that risankizumab is highly effective for treating conditions like psoriasis. In one study, 98.7% of patients experienced a significant reduction in their symptoms, with a 75% improvement in their Psoriasis Area and Severity Index, which measures the severity of psoriasis. Another study found that most patients maintained clear or nearly clear skin after a year of treatment. Risankizumab also proves effective for individuals with Crohn's disease, with real-world evidence indicating it benefits those who have tried other treatments. Overall, these findings suggest risankizumab can be a strong option for managing these conditions.

In this trial, healthy participants will receive a single dose of risankizumab via an On-Body Injector (OBI). One group will receive it produced by a new process, while another group will receive it produced by the current process. ^{1 2 6 7 8}

Published Research Related to This Trial

In a large analysis of 10,235 reports from the FDA Adverse Event Reporting System, risankizumab was associated with 161 adverse events (AEs), including unexpected ones like myocardial infarction and pancreatitis, highlighting the need for careful monitoring.

The study identified that most AEs related to risankizumab were reported as serious, with a significant number of cases showing a gradual decrease in reported AEs over time, suggesting that the risks may diminish with continued use.

Adverse events with risankizumab in the real world: postmarketing pharmacovigilance assessment of the FDA adverse event reporting system. Shu, Y., Chen, J., Ding, Y., et al.[2023]

In a study of 100 patients with moderate-to-severe Crohn's disease who had previously failed multiple treatments, risankizumab achieved a steroid-free clinical remission rate of 45.8% and a clinical response rate of 78.5% by week 12, indicating its effectiveness in a real-world setting.

The treatment was generally well-tolerated, with 20 adverse events reported, including 7 serious cases, but the majority of patients experienced significant improvements in their condition, highlighting risankizumab's potential as a viable option for refractory Crohn's disease.

In a long-term study of 65 patients with moderate-to-severe Crohn's disease, risankizumab was well tolerated over a median of 33 months, with no new safety concerns and a low rate of serious adverse events (24.6 events/100 patient-years).

Efficacy was maintained throughout the study, with over 71% of patients achieving clinical remission and more than 42% achieving endoscopic remission, indicating that risankizumab remains effective for long-term treatment.

In a 24-week Phase 3 trial involving patients with psoriatic arthritis who had inadequate responses to previous treatments, risankizumab (RZB) significantly improved patient-reported outcomes, including pain, fatigue, and overall health-related quality of life compared to placebo.

Patients treated with RZB reported better scores in multiple health assessments, including the SF-36 and FACIT-Fatigue, indicating enhanced ability to perform daily activities and work, demonstrating its efficacy in managing symptoms of psoriatic arthritis.

Risankizumab, an anti-IL23 monoclonal antibody, demonstrated linear pharmacokinetics in patients with active psoriatic arthritis (PsA), with a favorable safety profile and robust efficacy when administered at a regimen of 150 mg subcutaneously at weeks 0, 4, and every 12 weeks thereafter.

The study analyzed data from 1527 participants across multiple clinical trials, confirming that the pharmacokinetics of risankizumab in PsA are comparable to those in patients with plaque psoriasis, with no significant impact of covariates on drug exposure.
