OBI-902 for Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests OBI-902, a new treatment for various advanced or metastatic solid tumors. The goal is to determine the best dose and assess its safety and effectiveness. In the first part, researchers test different doses to identify the safest and most effective one. The second part examines how well the treatment works in specific cancers, such as breast cancer, endometrial cancer, and cholangiocarcinoma. Individuals with advanced cancers that do not respond to standard treatments or who have opted not to pursue them might be suitable for this trial. As a Phase 1/Phase 2 trial, this research aims to understand how the treatment works in people and measure its effectiveness in an initial, smaller group, offering participants a chance to be among the first to benefit from this new therapy.
Do I have to stop taking my current medications for the trial?
The trial information does not specify if you need to stop taking your current medications. However, you cannot participate if you are taking any medications that are specifically prohibited by the trial protocol.
Is there any evidence suggesting that OBI-902 is likely to be safe for humans?
Research has shown that OBI-902, a new cancer treatment, demonstrates promising safety features in early studies. In both lab and animal studies, it behaved consistently and was well-tolerated, meaning it remained stable and effective in the body. The treatment is an antibody-drug conjugate (ADC), which links a drug to an antibody. This design helps target cancer cells directly, minimizing harm to healthy cells. Although this information is encouraging, the testing process is still in its early stages. The trial aims to confirm these findings in humans and determine safe dosage levels.12345
Why do researchers think this study treatment might be promising?
Researchers are excited about OBI-902 because it offers a new approach to treating cancer by targeting and inhibiting specific proteins crucial for tumor growth. Unlike standard chemotherapies, which attack all rapidly dividing cells, OBI-902 works more selectively, potentially leading to fewer side effects. Additionally, this treatment is being explored at various dosage levels and in different cancer types, such as HER2-negative breast cancer and endometrial carcinoma, to optimize its effectiveness and broaden its application. With its unique mechanism of action and targeted approach, OBI-902 holds promise for improved outcomes in challenging cancer cases.
What evidence suggests that OBI-902 might be an effective treatment for cancer?
Research has shown that OBI-902, which participants in this trial may receive, could effectively treat various advanced solid tumors. Studies in lab models have demonstrated strong anti-tumor effects in cancers such as lung, pancreatic, stomach, and colorectal. OBI-902 targets a protein called TROP2, often found in high amounts in many cancers. Early tests suggested that it works better and is absorbed more effectively than similar treatments. These promising results offer hope for potential benefits for patients with different types of advanced cancers.13678

What Are the Treatments Tested in This Trial?
Interventions
- OBI-902
Trial Overview
The study is testing OBI-902 in two parts: Part A seeks the highest dose patients can tolerate without severe side effects (MTD), and Part B expands the cohort at this dose to assess safety and early signs of effectiveness.
