What is the mechanism of action of this treatment?

Common treatments for stomach cancer, particularly those involving immunotherapy like HFB200301 and tislelizumab, work by enhancing the body's immune response against cancer cells. Tislelizumab is a PD-1 inhibitor that blocks the interaction between PD-1 proteins on T-cells and PD-L1 proteins on cancer cells, preventing the cancer cells from evading immune detection. HFB200301, while its exact mechanism is not detailed, likely works synergistically with tislelizumab to further boost immune activity against tumors. Understanding these mechanisms is crucial for stomach cancer patients as it highlights the potential for these therapies to improve survival rates by leveraging the body's own immune system to target and destroy cancer cells more effectively.

What side effects are associated with this type of intervention?

Common treatments for stomach cancer, particularly those involving immunotherapy agents like HFB200301 and tislelizumab, often have side effects such as fatigue, diarrhea, and skin reactions (e.g., rash, dry skin). Immunotherapy can also lead to immune-related adverse events, including pneumonitis, colitis, hepatitis, and endocrinopathies. Chemotherapy, another common treatment, typically causes nausea, vomiting, hair loss, and increased risk of infections due to lowered blood cell counts. Targeted therapies may result in hypertension, hand-foot syndrome, and gastrointestinal issues. Patients should discuss these potential side effects with their healthcare provider to manage and mitigate them effectively.

What prior FDA approvals exist?

The FDA has approved several immunotherapies for the treatment of advanced stomach cancer. Pembrolizumab (Keytruda) is an anti-PD-1 monoclonal antibody approved for PD-L1-positive gastric or gastroesophageal junction adenocarcinoma, often used in combination with chemotherapy. Nivolumab (Opdivo), another anti-PD-1 therapy, has been approved for use in combination with chemotherapy for advanced or metastatic gastric cancer. These treatments are similar to the HFB200301 trial, which studies the combination of HFB200301 with tislelizumab, another PD-1 inhibitor, highlighting the ongoing exploration of immunotherapy combinations in advanced stomach cancer.

What other types of research exist?

Promising alternatives to HFB200301 for stomach cancer patients include pembrolizumab (a PD-1 inhibitor) and novel bispecific fusion proteins targeting 4-1BB and PD-L1, which have shown potential in preclinical and clinical studies. Additionally, combination therapies involving PD-L1 inhibitors like atezolizumab or durvalumab with chemotherapy have demonstrated improved survival outcomes in various cancers and may be considered.

Summary

This trial tests a new drug, HFB200301, alone and with another drug, tislelizumab, in adults with advanced cancers. Researchers will start with a low dose and gradually increase it to find the most suitable amount. They will then test this amount in more patients to see how well it works against different cancers.

Who is the study for?

Adults with advanced solid tumors like lung, kidney, or skin cancer who've had certain treatments already can join. They need to be well enough for daily activities and able to provide tumor samples. Excluded are those with severe lung conditions, recent major surgery, immune suppressive therapy, unstable health issues, or allergies related to the study drugs.

What is being tested?

The trial is testing HFB200301 alone and combined with Tislelizumab in two parts: first finding a safe dose (escalation) then giving that dose to more people based on their cancer type (expansion). It aims to see how patients tolerate these treatments.

What are the potential side effects?

Possible side effects include reactions similar to other monoclonal antibodies such as immune system complications, infusion-related reactions, fatigue, organ inflammation and increased risk of infections.
