What is the purpose of this trial?

This trial tests a new treatment called IKS03 for individuals with advanced B-cell non-Hodgkin lymphoma (NHL), a type of blood cancer. The goal is to determine a safe dose and assess the treatment's effects on the cancer and the immune system. Participants will receive IKS03 through an IV every 21 days until the cancer progresses or side effects become too severe. The trial seeks individuals with B-cell NHL that hasn't responded to at least two prior treatments and who are not in immediate need of intense therapy. As a Phase 1 trial, this research aims to understand how the treatment works in people, offering participants the opportunity to be among the first to receive this new therapy.

Will I have to stop taking my current medications?

The trial requires stopping certain medications before participating. You must not have taken any CD19-targeted therapy within 3 months, tumor vaccines within 6 weeks, or other investigational treatments within 4 weeks. Additionally, certain drugs that impair renal function, immunosuppressive therapies, and herbal supplements must be stopped within specified timeframes before joining the trial.

Is there any evidence suggesting that IKS03 is likely to be safe for humans?

Research shows that IKS03 is generally well-tolerated. In earlier studies, most side effects were mild. The most common serious side effect was a decrease in white blood cells, known as neutropenia, occurring in about 26% of participants. This condition can increase the risk of infections. Other side effects were less severe and manageable.

Additionally, IKS03 caused less reduction in B-cells compared to similar treatments, even at higher doses. This suggests it might lead to fewer issues related to the loss of healthy B-cells, which are crucial for the immune system. Overall, the safety data for IKS03 indicates it is mostly manageable for patients. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for lymphoma?

Researchers are excited about IKS03 for B-cell lymphoma because it offers a potential new approach by targeting the cancer cells directly. Most current treatments, like chemotherapy and targeted therapies such as rituximab, work by killing or marking cancer cells for the immune system to attack. IKS03, on the other hand, is believed to target specific pathways within the cancer cells, potentially leading to more effective results with fewer side effects. Additionally, it's administered intravenously in a cyclical manner, which might allow for better control of the treatment process and monitoring of its effects on patients over time. This novel mechanism of action is what makes IKS03 stand out and fuels researchers' optimism about its potential benefits.

What evidence suggests that IKS03 might be an effective treatment for B-cell lymphoma?

Research has shown that IKS03 may help treat B-cell lymphoma, including types like follicular, mantle cell, and diffuse large B-cell lymphoma. In early lab studies, IKS03 completely shrank or eliminated tumors in a type of B-cell lymphoma with the CD19 protein. IKS03 targets this CD19 protein to attack cancer cells and has demonstrated strong effects in aggressive B-cell lymphoma models. This trial includes various treatment arms where participants with different types of B-cell lymphoma will receive IKS03. While these early results are promising, further research is needed to confirm its safety and effectiveness in people. ^{1 4 6 7 8}

KA2237, a dual inhibitor of p110β and p110δ, showed promising efficacy in treating various types of B cell lymphomas, achieving an overall response rate of 37% in a phase I study with 21 patients.

While KA2237 demonstrated the ability to induce objective responses, it also had a high incidence of treatment-related adverse events, with 86% of patients experiencing side effects, leading to a 33% discontinuation rate due to these adverse events.

In a study of 353 lymphoma cases, BCL-3 expression was found in 6% of B-cell lymphomas and 23% of T/NK-cell lymphomas, suggesting its potential role in the development of these cancers.

Notably, 41% of Hodgkin lymphomas tested positive for BCL-3, indicating that targeting BCL-3 could be a promising strategy for new therapies in certain lymphoma types.

BCL3 is frequently targeted by growth-promoting cytokines in myeloma cells, and its increased expression is linked to enhanced cell proliferation.

In a study of 351 newly diagnosed myeloma patients, high levels of BCL3 expression were associated with a poorer 5-year survival rate, suggesting its potential role as an oncogene and a prognostic marker in multiple myeloma.

BCL3 rearrangement (BCL3-R) in lymphoid neoplasms is associated with two distinct clinical entities based on the location of the breakpoints, with upstream breakpoints leading to overexpression of BCL3 and linked to atypical chronic lymphocytic leukemia (CLL) features.

Downstream breakpoints of BCL3-R are associated with marginal zone lymphomas (MZL) and exhibit different genomic and clinical characteristics, including mutated IGHV and complex karyotypes, highlighting the importance of breakpoint location in determining the type and behavior of the neoplasm.

Transgenic mice overexpressing the BCL3 gene showed normal development but exhibited splenomegaly and an accumulation of mature B cells, indicating that BCL3 may play a role in B cell proliferation and immune response.

Despite the observed immune system hyperactivity and changes in antibody levels, no lymphoid neoplasms were found in these transgenic mice, suggesting that while BCL3 overexpression contributes to B cell expansion, it may not directly lead to cancer in this model.

BTK inhibitors (BTKis) have significantly improved treatment for chronic lymphocytic leukemia (CLL) by targeting Bruton's tyrosine kinase, which is crucial for B-cell receptor signaling, leading to reduced cell proliferation and activation of harmful pathways.

While BTKis like ibrutinib and acalabrutinib are effective, they come with notable long-term adverse effects, including cardiac issues and infections, highlighting the need for careful management of these side effects during treatment.

The study investigated the role of KIR3DL1 and KIR3DS1 genotypes in the pathogenesis of endemic Burkitt lymphoma (eBL) among 108 eBL patients and 99 healthy controls in Kenya, finding no significant differences in genotype frequencies between the two groups.

The results suggest that variations in KIR3DL1 and KIR3DS1 genotypes are not major contributors to eBL development, although the complexity of the KIR3DL1 locus means that other genetic factors, such as copy number variations, could still play a role.

IMP-3 is primarily expressed in germinal center B cells of normal lymphoid tissue, but is overexpressed in various lymphoid neoplasms, particularly in Hodgkin lymphoma where 100% of cases showed positive staining.

The presence of IMP-3 in lymphoid neoplasms, especially in Hodgkin and Burkitt lymphomas, suggests a potential diagnostic or therapeutic role, although its expression is less pronounced in other lymphoma types.

The combination of umbralisib (a PI3K-δ inhibitor) and ublituximab (an anti-CD20 monoclonal antibody) was well tolerated in patients with chronic lymphocytic lymphoma (CLL) and non-Hodgkin lymphoma (NHL), with only one dose-limiting toxicity observed and low rates of severe side effects.

The overall response rate to the U2 combination therapy was 46%, with a median duration of response of 20 months, indicating promising preliminary efficacy that supports further research.

In a study of 23 leukemia patients undergoing cord blood transplantation (CBT), those with a mismatch between killer cell immunoglobulin receptor (KIR) and HLA-C showed higher engraftment (65%) and overall survival rates (70%) compared to matched groups (50% for both).

The presence of homo-expression of HLA-Cw1 or Cw2 also correlated with better outcomes, while co-expression of KIR2DL2 and KIR2DS2 was associated with disease-free survival, highlighting the importance of KIR in predicting CBT success.

The novel IKK2 inhibitor LY2409881 effectively inhibits tumor growth and induces apoptosis in lymphoma cells by targeting the NF-κB pathway, demonstrating significant activity in preclinical models, including a xenograft mouse model.

LY2409881 shows a safe profile in mice at various doses (50, 100, and 200 mg/kg) and exhibits marked synergy when combined with the HDAC inhibitor romidepsin, suggesting a promising new treatment strategy for B- and T-cell lymphoma.

Treatment with IPH2101, aimed at enhancing natural killer (NK) cell function in smoldering multiple myeloma, unexpectedly led to a reduction in NK cell function due to a process called monocyte trogocytosis.
