What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new treatment called AI-081, an antibody therapy for individuals with advanced solid tumors, to assess its safety and effectiveness. Participants receive the treatment through an IV infusion every three weeks. Those diagnosed with advanced or spreading solid tumors who can engage in daily activities might be suitable candidates. The trial aims to learn more about AI-081's effects on the body and its efficacy against cancer. As a Phase 1 trial, participants will be among the first to receive this treatment, aiding researchers in understanding its effects in humans.

Will I have to stop taking my current medications?

The trial does not specify if you must stop taking your current medications, but it does allow for certain supportive treatments like thyroxine, insulin, and steroid replacement. There is a 28-day washout period for treatments with monoclonal antibodies.

Is there any evidence suggesting that AI-081 is likely to be safe for humans?

Research has shown that AI-081 is very safe in early testing. Studies found that even at the smallest dose tested (1 mg/kg), AI-081 was well-tolerated, with most patients experiencing no serious side effects. This treatment is a bispecific antibody, targeting two proteins in the body, PD-1 and VEGF, which are involved in cancer growth.

The current trials are in Phase 1-2, indicating they are still in the early stages of testing to assess the treatment's safety and mechanism in the body. Although more testing is needed to fully understand its safety, early results are promising for people with advanced cancer. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Researchers are excited about AI-081 because it represents a novel approach to treating advanced cancer. Unlike traditional cancer treatments that often rely on chemotherapy or radiation to kill cancer cells, AI-081 is an antibody designed to specifically target and bind to cancer cells, potentially sparing healthy cells and reducing side effects. This targeted mechanism of action could offer a more precise and effective treatment option. Additionally, AI-081 is administered via IV infusion every three weeks, which might offer a more convenient dosing schedule compared to some existing therapies.

What evidence suggests that AI-081 might be an effective treatment for advanced cancer?

Research has shown that AI-081, a new treatment under study in this trial, could aid in managing advanced solid tumors. It targets two key cancer areas: PD-1 and VEGF, which assist tumors in growing and evading the immune system. Early studies found that AI-081 blocks these areas more effectively than similar treatments. Even at low doses, patients responded well, indicating the treatment's effectiveness. This makes AI-081 a promising option for treating challenging cancers. ^{1 2 3 4 6}

The study developed a one-time application of a genetically engineered immune checkpoint inhibitor (ICI) using a recombinant adeno-associated vector (rAAV) that targets PD-L1, showing significant protection against tumor growth in mouse models of colorectal and breast cancer.

This approach led to enhanced CD8+ T-cell function and a favorable shift in the tumor microenvironment, indicating that rAAV-PD-L1-scFv could be a safer and more effective alternative to traditional monoclonal antibodies in cancer therapy.

The hybridoma clone C3A8 produces a specific IgM monoclonal antibody that strongly binds to MCF7 breast cancer and HT29 colon cancer cells, while showing minimal reactivity with HeLa cells, indicating its potential for targeted cancer research.

MAb C3A8 can detect a specific 55 kDa protein in cancer cell extracts and has shown positive reactions in human breast and colon cancer tissues, but not in normal tissues, suggesting its utility in distinguishing cancerous from healthy tissues.
