What is the purpose of this trial?

This trial tests a new treatment combination to prevent complications after a bone marrow transplant for individuals with certain blood cancers. It uses VIC-1911, an experimental drug, alongside other medications to reduce the risk of graft-versus-host disease (GVHD), which occurs when transplanted cells attack the body. Individuals who have recently undergone a bone marrow transplant and are in remission from acute leukemia, or have specific other blood conditions, may qualify for this trial. Participants must be able to take oral medication and have no active infections. As a Phase 1 trial, this research aims to understand how the treatment works in people, offering participants the chance to be among the first to receive this new treatment.

Do I need to stop my current medications for this trial?

The trial information does not specify if you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is there any evidence suggesting that this trial's treatment is likely to be safe?

Research has shown that using sirolimus with post-transplant cyclophosphamide (PTCy) is safe and reduces complications after a transplant. This provides insight into the safety of adding VIC-1911 to the treatment.

Early studies with VIC-1911 are encouraging. Patients have shown positive outcomes without severe side effects that would necessitate stopping or lowering the dose. This indicates that VIC-1911 is well-tolerated at the doses tested.

As this study is still in the early stages, more information will emerge as research progresses. However, based on current data, the treatment appears safe for individuals. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard of care for acute leukemia, which often involves chemotherapy and radiation, VIC-1911 works differently by specifically targeting cancer cell growth at a molecular level. Researchers are excited about this treatment because it combines PTCy and sirolimus with VIC-1911, potentially offering a more tailored approach to post-transplant care. This combination therapy aims to reduce transplant-related complications and improve patient outcomes by leveraging the unique properties of VIC-1911 to potentially enhance the immune system's ability to fight residual cancer cells.

What evidence suggests that PTCy/sirolimus plus VIC-1911 is effective for preventing GVHD and relapse after alloHCT?

Research has shown that using sirolimus with post-transplant cyclophosphamide (PTCy) reduces complications after a transplant. In this trial, participants will receive a combination of PTCy, sirolimus, and VIC-1911. VIC-1911 blocks AURKA, which is crucial for cancer cell growth. Earlier studies demonstrated positive results with this combination, suggesting it might help prevent cancer recurrence and reduce post-transplant issues. Specifically, the likelihood of remaining leukemia-free has significantly improved, indicating this method's potential effectiveness. Overall, this treatment combination appears promising for enhancing outcomes in people with acute leukemia after a transplant. ^{2 3 6 7 8}

Exclusion Criteria

I agree to use birth control during and for 60 days after treatment.

I cannot undergo intense bone marrow radiation due to high risk.

Published Research Related to This Trial

Sirolimus has become a foundational therapy for immunosuppression in transplant patients, significantly reducing the risk of acute allograft rejection by allowing over 80% reduction in calcineurin inhibitor exposure, which leads to better long-term renal function despite some increased risks of lymphoceles and impaired wound healing.

The drug also has anti-cancer properties by inhibiting mTOR, reducing tumor incidence in patients, and is relatively non-nephrotoxic, allowing for the withdrawal of steroid therapy and lower rates of viral infections, making it a promising option in immunosuppressive regimens.

Fifteen years of clinical studies and clinical practice in renal transplantation: reviewing outcomes with de novo use of sirolimus in combination with cyclosporine. Kahan, BD.[2014]

In a study of 242 adult patients with acute myeloid leukemia (AML) undergoing their first allogeneic stem cell transplant, the combination of sirolimus and post-transplant cyclophosphamide (Sir-PTCy) was found to be a safe and effective method for preventing graft-versus-host disease (GvHD).

The use of Sir-PTCy resulted in low rates of transplant-related mortality, relapse, and both acute and chronic GvHD across various donor types, indicating its potential as a reliable prophylactic strategy in AML patients.
