What is the purpose of this trial?

This trial aims to test the effectiveness and safety of a new treatment called Afimkibart (also known as RO7790121) for people with Crohn's disease, a condition that causes inflammation in the digestive tract. Participants will receive either Afimkibart or a placebo (a substance with no active drug) to compare results. The trial seeks individuals with moderate to severe Crohn's disease who have not responded well to other treatments. The study aims to find a new option for those struggling with Crohn's disease symptoms. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to a potentially groundbreaking treatment.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, it mentions that certain medicines are prohibited, so it's best to discuss your current medications with the trial team.

Is there any evidence suggesting that RO7790121 is likely to be safe for humans?

Research has shown that Afimkibart (RO7790121) has been tested in people with moderately to severely active Crohn's disease. In these studies, most patients tolerated Afimkibart well. Some experienced side effects, usually mild, such as headaches and nausea, while serious side effects were rare.

Since this treatment is in a Phase 3 trial, it has already passed earlier safety tests. These earlier phases demonstrated it was safe enough for broader testing, which is a positive indicator for its safety in humans. However, like any treatment, risks exist, and it is important to consider them before joining a trial. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for Crohn's disease?

Researchers are excited about afimkibart for Crohn's Disease because it offers a new approach to treatment. Most current treatments, like biologics and immunosuppressants, work by broadly dampening the immune system. However, afimkibart specifically targets pathways involved in the inflammation process, potentially reducing side effects and improving effectiveness. Additionally, its dual delivery method, starting with an intravenous (IV) dose followed by a subcutaneous (SC) injection, may enhance its absorption and convenience for patients. This targeted approach and delivery method set afimkibart apart from traditional therapies.

What evidence suggests that RO7790121 might be an effective treatment for Crohn's disease?

Research has shown that Afimkibart, also known as RO7790121, may help treat moderate to severe Crohn's disease. In this trial, participants will receive either Afimkibart or a placebo. Studies have found that patients taking Afimkibart experienced significant symptom improvements. Specifically, one study revealed that almost half of the patients noticed benefits during the early treatment stage, and more than half continued to improve later on. These results suggest that Afimkibart could be a helpful option for managing Crohn's disease symptoms. ^{1 2 3 6 7}

What Are the Treatments Tested in This Trial?

Interventions

• RO7790121

Trial Overview

The study tests RO7790121 against a placebo in people with moderate to severe Crohn's Disease. It's a Phase III trial where participants are randomly assigned to receive either the experimental drug or an inactive substance without knowing which one they get (double-blind).

How Is the Trial Designed?

Group I: Afimkibart Experimental Treatment 1 Intervention

Participants will receive afimkibart intravenously (IV) followed by afimkibart subcutaneous (SC) injection.

Group II: Placebo Placebo Group 1 Intervention

Participants will receive placebo IV followed by afimkibart SC injection.

Published Research Related to This Trial

Infliximab treatment led to a rapid remission in 88% of patients with steroid-refractory Crohn's disease after just one week, but the long-term effectiveness decreased significantly over time, with only 8% remaining in remission by 16 weeks.

Patients who relapsed after initial remission showed increased TNF-alpha secretion and elevated levels of nuclear NFkappaB p65 in their mucosal biopsies, indicating that these immune markers may predict clinical relapse.

Risankizumab was evaluated as an induction therapy for Crohn's disease in two phase 3 trials (ADVANCE and MOTIVATE), demonstrating significant efficacy in achieving clinical remission among participants.

The results indicated that risankizumab effectively reduced disease activity in patients with Crohn's disease, suggesting it could be a promising treatment option for managing this condition.

In a 52-week study involving 24 patients with Crohn's disease who previously lost response to infliximab, adalimumab demonstrated significant efficacy, with clinical remission rates increasing from 35% at baseline to 58% at week 52.

Adalimumab was well tolerated, with no patients experiencing intolerance and no serious toxicities reported, indicating it is a safe option for maintaining remission in these patients.

In a phase 2 trial involving 220 adults with moderate to severe Crohn's disease, upadacitinib demonstrated significant efficacy in inducing endoscopic remission, particularly at the 24 mg dose, compared to placebo.

While upadacitinib showed promising results, it was associated with higher rates of infections and increased cholesterol levels, indicating a need to carefully consider its safety profile in future treatments.

In a study of 6,273 Crohn's disease patients with an average follow-up of 5.2 years, infliximab treatment did not increase mortality risk compared to other treatments, indicating its long-term safety in this regard.

However, infliximab was associated with a higher risk of serious infections, although this risk was also influenced by the severity of the disease and the use of medications like prednisone and narcotics.

In a long-term study of 107 patients with Crohn's disease, upadacitinib demonstrated sustained clinical remission rates of around 54-61% over 30 months, indicating its efficacy as a treatment.

While upadacitinib showed long-term benefits, the safety profile revealed that higher doses (30 mg) were associated with increased rates of adverse events compared to lower doses (15 mg), consistent with its known safety profile.

In a study of 221 Crohn's disease patients treated with ustekinumab over a median follow-up of 52 weeks, 38.2% achieved corticosteroid-free clinical remission by week 24, and 37.1% by week 52, indicating its effectiveness in managing the disease.

Ustekinumab was found to be relatively safe, with a low incidence of severe infections (3.5 per 100 patient-years), and treatment discontinuation primarily occurred due to lack of response, affecting 33.9% of patients.

Nayar et al. identified specific inflammatory cell populations that play a role in the development of Crohn's disease (CD), highlighting the importance of understanding these cells in disease management.

The study suggests that targeting the gp130-STAT3 signaling pathway could be a promising new treatment strategy for patients with CD who do not respond to anti-TNF antibody therapies, potentially enhancing existing treatment options.
