What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a combination of nivolumab and ASTX727 in patients with B-cell lymphoma that has come back or is not responding to treatment. Nivolumab helps the immune system attack cancer, while ASTX727 enhances the effectiveness of another drug. The goal is to find a safe and effective dose for these patients.

Will I have to stop taking my current medications?

The trial protocol does not specify if you must stop taking your current medications. However, you cannot participate if you need systemic corticosteroids or other immunosuppressive medications within 14 days of starting the study drugs. It's best to discuss your specific medications with the trial team.

Is the combination of Nivolumab and ASTX727 safe for humans?

The combination of decitabine and cedazuridine (ASTX727) has been studied for safety in humans, showing common side effects like neutropenia (low white blood cell count) and thrombocytopenia (low platelet count). These side effects were consistent with those seen in intravenous decitabine treatments. Further studies are needed to assess the safety of combining this with Nivolumab. ^{1 2 3 4 5}

What makes the drug Nivolumab + ASTX727 unique for B-Cell Lymphoma?

This drug combination is unique because it combines Nivolumab, an immune checkpoint inhibitor that blocks the PD-1 pathway to help the immune system attack cancer cells, with ASTX727, which includes Decitabine and Cedazuridine to enhance the effectiveness of the immune response by modifying DNA. This approach targets both immune evasion and genetic instability in B-cell lymphoma, offering a novel strategy compared to traditional chemotherapy. ^{6 7 8 9 10}

What data supports the effectiveness of the drug Nivolumab + ASTX727 for B-Cell Lymphoma?

Research shows that combining decitabine, a component of ASTX727, with PD-1 inhibitors (a type of drug that includes nivolumab) has shown positive results in treating certain types of lymphoma, like Hodgkin lymphoma, especially in patients who did not respond well to PD-1 inhibitors alone. ^{3 4 9 11 12}

Published Research Related to This Trial

In a phase II trial involving 51 patients with relapsed/refractory classical Hodgkin lymphoma (cHL) who previously failed anti-PD-1 therapy, the combination of decitabine and camrelizumab showed a high objective response rate of 52% in the test cohort and 68% in the expansion cohort, indicating its efficacy as a treatment option.

Patients receiving this combination therapy experienced a median progression-free survival of 20.0 months in the test cohort and 21.6 months in the expansion cohort, which is significantly longer than the outcomes from prior anti-PD-1 monotherapy, suggesting durable benefits from this treatment.

Efficacy of Decitabine plus Anti-PD-1 Camrelizumab in Patients with Hodgkin Lymphoma Who Progressed or Relapsed after PD-1 Blockade Monotherapy. Wang, C., Liu, Y., Dong, L., et al.[2022]

In a study of 61 patients with relapsed/refractory classical Hodgkin lymphoma, the combination of decitabine and camrelizumab resulted in a significantly higher complete remission rate of 79% compared to 32% with camrelizumab alone, indicating enhanced efficacy of the combination therapy.

The median progression-free survival (PFS) was 35.0 months for the decitabine-plus-camrelizumab group versus 15.5 months for camrelizumab monotherapy, suggesting that the combination therapy not only improves remission rates but also prolongs the time patients remain free from disease progression.

The fixed-dose oral combination of decitabine and cedazuridine (Inqovi®) has been approved for treating myelodysplastic syndromes (MDS) and chronic myelomonocytic leukaemia (CMML), enhancing the oral bioavailability of decitabine through the inhibition of cytidine deaminase by cedazuridine.

Decitabine is already an established treatment for MDS and CMML, and the combination therapy has shown promise in ongoing clinical studies for other cancers like acute myeloid leukaemia (AML), glioma, and solid tumors.

In a trial involving 56 patients with relapsed/refractory diffuse large B-cell lymphoma, the combination of decitabine with the RDHAP regimen showed a higher duration of remission compared to RDHAP alone, indicating potential benefits in treatment longevity.

The overall response rates were similar between the decitabine-RDHAP group (40%) and the RDHAP group (33%), but both regimens had comparable safety profiles, suggesting that decitabine-RDHAP is a well-tolerated option for patients.

Inqovi, a combination of decitabine and cedazuridine, was approved by the FDA for treating myelodysplastic syndromes (MDS) based on a phase III study involving 133 adults, showing similar effectiveness to intravenous decitabine.

The treatment demonstrated a complete remission rate of 21% in one study and 18% in another, with a median duration of remission lasting around 7.5 to 8.7 months, while adverse reactions were consistent with those seen in IV decitabine.

The phase 2 study found that oral cedazuridine/decitabine (100 mg/35 mg) provided similar systemic exposure and DNA demethylation compared to standard IV decitabine (20 mg/m2) in patients with myelodysplastic syndromes or chronic myelomonocytic leukemia, indicating comparable efficacy.

Clinical responses were observed in 60% of patients, with 21% achieving a complete response, while the most common serious side effects included neutropenia (46%) and thrombocytopenia (38%), highlighting the treatment's safety profile.

In a pilot clinical trial involving 7 patients with relapsed lymphoid malignancies, the combination of decitabine and the CDA-inhibitor tetrahydrouridine showed some clinical improvements in 4 patients, but treatment interruptions due to neutropenia limited the effectiveness of the therapy.

Preclinical studies suggested that alternating decitabine with 5-azacytidine and using additional inhibitors could enhance the treatment's effectiveness against lymphoma while reducing the risk of neutropenia, indicating the need for regimen innovations to improve outcomes.

In refractory diffuse large B-cell lymphoma (DLBCL), particularly the activated B-cell-like (ABC) subtype, the p53 DNA damage response plays a crucial role in suppressing tumor progression driven by NF-κB activation and impaired B-cell differentiation.

Combining PD-1 blockade with anti-CD20 therapy showed promising results in mice, enhancing T-cell reactivation and improving long-term survival, suggesting that this combination could be an effective immunotherapy strategy for ABC-DLBCL.

In a phase II study involving 121 patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL), nivolumab showed a low overall response rate of 10% in those who failed autologous hematopoietic cell transplantation (auto-HCT) and 3% in those ineligible for auto-HCT, indicating limited efficacy in this patient population.

Despite the low response rates, nivolumab demonstrated a favorable safety profile, with only 24% of patients experiencing grade 3 or 4 adverse events, primarily neutropenia and thrombocytopenia.
