What is the purpose of this trial?

This trial aims to determine the safest dose of a new drug, SB-4826, for treating solid tumors and non-Hodgkin's lymphoma, a type of cancer affecting the lymphatic system. Researchers seek to understand how the body processes the drug and its effectiveness against cancer. The trial tests SB-4826 alone in some cases and with another drug, rituximab, in others. It suits individuals with non-Hodgkin's lymphoma or advanced solid tumors who have experienced symptoms like fevers, weight loss, or night sweats after other treatments. Participants will take SB-4826 every other day and undergo regular checkups. As a Phase 1 trial, this research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new treatment.

Will I have to stop taking my current medications?

The trial protocol does not specify if you must stop taking your current medications, but it does exclude those using certain cancer therapies, cellular therapies, or specific medications affecting liver enzymes within a certain timeframe before starting the trial. It's best to discuss your current medications with the trial team to see if they might affect your eligibility.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Studies are testing SB-4826 to find the safest dose for patients with solid tumors and non-Hodgkin lymphomas. The main goal is to determine the maximum amount of the drug that can be administered without causing serious side effects. Earlier research found that doses of 60 mg or more were generally safe, leading to a recommended dose of 90 mg taken twice a week.

When combined with rituximab for non-Hodgkin lymphoma patients, safety remains a priority. Rituximab has been used for a long time, with known side effects such as fever, chills, and nausea, mostly occurring during the first infusion (administered intravenously).

Overall, the studies are still in early stages, so safety data is limited. However, SB-4826, both alone and with rituximab, undergoes careful monitoring to ensure it is well-tolerated. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Unlike the standard treatment options for Non-Hodgkin's Lymphoma, such as chemotherapy and monoclonal antibodies like rituximab, SB-4826 introduces a novel approach. Researchers are excited about SB-4826 because it potentially targets cancer cells differently, offering a new mechanism of action. In particular, SB-4826 is being tested both as a monotherapy and in combination with rituximab, potentially enhancing the effectiveness of existing treatments. These trials aim to determine if SB-4826 can improve outcomes by being more effective in killing cancer cells or reducing side effects compared to current therapies.

What evidence suggests that SB-4826 might be an effective treatment for non-Hodgkin's lymphoma?

Research has shown that SB-4826 could be a promising treatment for non-Hodgkin's lymphoma. Early results suggest that SB-4826 blocks a process that helps cancer cells survive, which could be a major breakthrough for patients with limited treatment options. In this trial, some participants will receive SB-4826 as monotherapy, while others will receive it in combination with rituximab. When combined with rituximab, a drug already proven to treat non-Hodgkin's lymphoma, the combination has demonstrated high success rates. Rituximab alone has been effective, especially for patients whose cancer has returned or is difficult to treat. Overall, early evidence supports the potential of SB-4826, particularly when combined with rituximab. ^{1 6 7 8 9}
