What You Need to Know Before You Apply

What is the purpose of this trial?

This study will be conducted to determine the preliminary efficacy of axatilimab in combination with ruxolitinib and to assess the contribution of axatilimab to the combination treatment effect in participants with cGVHD.

Do I need to stop my current medications to join the trial?

The trial protocol does not specify if you need to stop taking your current medications. However, you cannot have received systemic corticosteroids or started certain treatments like CNIs or mTOR inhibitors within 2 weeks before the trial begins, and you must not have used a JAK inhibitor within 8 weeks before joining.

Is the combination of Axatilimab and Ruxolitinib safe for treating graft-versus-host disease?

Ruxolitinib, used for treating graft-versus-host disease, has been generally well-tolerated in patients, though some have experienced serious side effects like infections and respiratory issues. Safety data from various studies suggest it is generally safe, but patients should be aware of potential risks. ^{1 2 3 4 5}

What makes the drug Axatilimab + Ruxolitinib unique for treating graft-versus-host disease?

This treatment combines Axatilimab, a novel drug, with Ruxolitinib, a JAK1/2 inhibitor that has shown effectiveness in treating graft-versus-host disease by targeting specific pathways involved in the immune response. This combination may offer a new approach for patients who do not respond to standard treatments like corticosteroids. ^{4 5 6 7 8}

What data supports the effectiveness of the drug Axatilimab + Ruxolitinib for Graft-versus-Host Disease?

Ruxolitinib, a component of the treatment, is approved for chronic graft-versus-host disease and has shown effectiveness in both acute and chronic forms of the condition, especially in patients who do not respond to steroids. ^{4 5 7 8 9}

Published Research Related to This Trial

Ruxolitinib (Jakafi) has received approval for the treatment of chronic graft-vs-host disease, indicating its efficacy in managing this condition.

The approval of ruxolitinib highlights its role as a kinase inhibitor, which works by targeting specific pathways involved in the immune response, potentially improving patient outcomes.

New Indication for Ruxolitinib. Aschenbrenner, DS.[2023]

Ruxolitinib prophylaxis showed a 41.2% incidence of acute graft-versus-host disease (aGVHD) in patients after modified donor lymphocyte infusion, indicating it can help reduce the severity of aGVHD in high-risk leukemia patients post-transplant.

Among the 17 patients studied, 58.8% achieved a complete response, suggesting that ruxolitinib may effectively maintain the graft-versus-leukemia (GVL) effect while managing aGVHD, despite a median follow-up of only 8 months.

In a study of 8 patients with acute or chronic graft versus host disease (GVHD) who were unresponsive to standard treatments, ruxolitinib demonstrated a high overall response rate of 85%, with 50% achieving complete response.

Ruxolitinib was well-tolerated, indicating it could be a promising rescue therapy for patients suffering from refractory GVHD.

In a study of 156 patients with steroid-refractory acute graft-versus-host disease (aGvHD), treatment with MSC-FFM showed an overall response rate of 46% in adults and 64% in children, indicating its potential effectiveness in this challenging condition.

The median overall survival for patients treated with MSC-FFM was 5.8 months, significantly better than the 28 days reported for patients not receiving MSC treatment, highlighting the potential benefit of MSC-FFM in improving survival outcomes.

Real-world data suggest effectiveness of the allogeneic mesenchymal stromal cells preparation MSC-FFM in ruxolitinib-refractory acute graft-versus-host disease. Bonig, H., Verbeek, M., Herhaus, P., et al.[2023]

In a study of 29 children with steroid-refractory acute graft-versus-host disease (aGVHD), ruxolitinib demonstrated a high overall response rate of 72.4%, with 19 patients achieving complete response by a median of 41 days after treatment initiation.

Ruxolitinib was well-tolerated, with no severe hematological adverse events reported, suggesting it is a promising second-line treatment option for this condition, although further validation in larger trials is needed.

In a study of 57 patients undergoing alternative donor transplantation for acute leukemia, early application of ruxolitinib significantly reduced the incidence of acute graft-versus-host disease (aGVHD) compared to the control group (22% vs. 50%).

Ruxolitinib was well tolerated, with no significant differences in overall survival or disease-free survival between the ruxolitinib and control groups, indicating its safety and efficacy in preventing aGVHD without compromising other health outcomes.

Ruxolitinib early administration reduces acute GVHD after alternative donor hematopoietic stem cell transplantation in acute leukemia. Zhang, B., Chen, L., Zhou, J., et al.[2021]

In a study of 29 patients with graft versus host disease (GvHD), Ruxolitinib exposure was found to be significantly higher than in myelofibrosis patients, indicating altered drug metabolism in GvHD.

Increased Ruxolitinib levels were linked to reduced drug clearance and the use of CYP3A4 or CYP2C9 inhibitors, suggesting that higher trough concentrations may indicate a risk of toxicity and necessitate careful monitoring.

Ruxolitinib exposure in patients with acute and chronic graft versus host disease in routine clinical practice-a prospective single-center trial. Isberner, N., Kraus, S., Grigoleit, GU., et al.[2022]

In an expanded access program involving 609 patients (60 with acute GVHD and 549 with chronic GVHD), ruxolitinib demonstrated a tolerable safety profile, with serious adverse events (SAEs) reported in 68.3% of acute and 33.9% of chronic GVHD patients.

The most common SAEs included infections, with sepsis and respiratory failure being prevalent in acute GVHD, indicating that while ruxolitinib is generally well-tolerated, careful monitoring for infections is necessary.

In a study of 20 pediatric and young adult patients with chronic graft versus host disease (cGVHD), ruxolitinib showed a 70% overall response rate, with 2 patients achieving complete response and 12 achieving partial response after a median of 48 days.

The dosing strategy of ruxolitinib was effective in inhibiting JAK signaling, as indicated by decreased phosphorylation of STAT5 in lymphocytes, although some patients experienced side effects like neutropenia and infections.
