What side effects are associated with this type of intervention?

Treatments for solid tumors involving immune system modulation and immune checkpoint inhibition, such as BI 1831169 and ezabenlimab, commonly cause side effects like fatigue, rash, diarrhea, and pruritus. More severe but less frequent side effects include pneumonitis, colitis, hepatitis, endocrinopathies, and nephritis. These adverse events result from the immune system attacking normal tissues and require careful monitoring and management, often with immunosuppressive therapies.

What prior FDA approvals exist?

The FDA has approved several drugs for the treatment of solid tumors that involve immune system modulation and immune checkpoint inhibition. Notable examples include Pembrolizumab and Nivolumab, both of which are PD-1 inhibitors used in various cancers such as melanoma, non-small cell lung cancer, and head and neck cancer. Ipilimumab, a CTLA-4 inhibitor, is another approved drug for melanoma. These treatments work by enhancing the body's immune response against cancer cells, similar to the investigational drugs BI 1831169 and Ezabenlimab being studied for their potential to help the immune system fight cancer.

What other types of research exist?

Promising alternatives to BI 1831169 and Ezabenlimab for solid tumor patients include Pembrolizumab and Nivolumab, both of which are immune checkpoint inhibitors. Pembrolizumab has shown efficacy in various cancers, including melanoma and non-small cell lung cancer, while Nivolumab has been effective in melanoma, renal cell carcinoma, and non-small cell lung cancer. Additionally, combination therapies such as Pembrolizumab with chemotherapy or Nivolumab with Ipilimumab are also promising options.

Summary

This trial is for adults with advanced cancers that can be injected and who have no other treatment options. It tests a new medicine, BI 1831169, alone and with another medicine, ezabenlimab, to see if they can help the immune system fight cancer. The study aims to find the highest safe doses and check if the medicines can shrink tumors.

Who is the study for?

Adults with advanced solid tumors that haven't responded to previous treatments or have no other options can join. They need at least one tumor suitable for injection and biopsy, be over 18 years old, in good health for trial procedures, have a performance status of 0 or 1, and proper organ function. Patients must not have had recent radiation to the target lesions or suffer from conditions like uncontrolled HIV/AIDS.

What is being tested?

The study is testing BI 1831169 alone and combined with ezabenlimab on different types of advanced cancers. Part one determines the highest tolerable dose of BI 1831169; part two does the same for its combination with ezabenlimab. Treatments are given every three weeks via injection into the tumor or infusion into a vein.

What are the potential side effects?

Potential side effects include typical immune-related reactions such as inflammation in various organs due to an activated immune system fighting cancer cells, possible allergic responses to treatment components, fatigue from body's response to therapy, and infection risks.

Other Research

The most common treatments for solid tumors often involve immune system modulation and immune checkpoint inhibition. Immune system modulation, as seen with BI 1831169, aims to enhance the body's immune response against cancer cells by activating immune cells directly within the tumor environment. Immune checkpoint inhibitors, like ezabenlimab, work by blocking proteins that prevent immune cells from attacking cancer cells, thereby allowing the immune system to recognize and destroy these cells more effectively. These mechanisms are crucial for solid tumor patients because they offer a targeted approach to treatment, potentially leading to better outcomes with fewer side effects compared to traditional therapies like chemotherapy. By harnessing the body's own immune system, these treatments can provide a more personalized and effective cancer therapy.
