What is the purpose of this trial?

This trial tests a new drug, IMGS-001, to determine its safety and effectiveness in treating advanced solid tumors. It targets patients whose cancer has returned or progressed after standard treatments. The first part tests different doses of IMGS-001 to identify the safest dose. The second part further evaluates two doses in specific cancer types, including ovarian, colorectal, non-small cell lung, nasopharyngeal, head and neck, and cervical cancers. Those who have tried other treatments without success, especially for these cancers, might be suitable for this trial. As a Phase 1 trial, this research aims to understand how the treatment works in people, offering participants the opportunity to be among the first to receive this new drug.

Will I have to stop taking my current medications?

The trial requires that you stop taking any investigational or conventional anti-cancer drugs within 21 days before starting the trial. You also need to stop using immunosuppressive medications 14 days before starting, except for certain allowed ones. If you are on androgen deprivation therapy for prostate cancer, you must continue it.

Is there any evidence suggesting that IMGS-001 is likely to be safe for humans?

Research shows that IMGS-001 is being tested for safety in patients with advanced cancer. In earlier studies, researchers tested the drug in patients with solid tumors to determine the highest dose they could tolerate without severe side effects.

The treatment remains in the early testing phase (Phase 1), where researchers primarily assess the drug's safety and patient tolerance. Detailed safety information from these studies is not yet available. However, the continuation of the trial suggests that earlier results were promising enough to proceed.

For those considering joining a trial, it is important to understand that the main goal at this stage is to ensure the treatment's safety. This involves closely monitoring for any harmful side effects. Always consult a healthcare provider to fully understand what participation might involve. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Researchers are excited about IMGS-001 because it offers a novel approach to treating advanced cancers with its unique mechanism of action. Unlike standard chemotherapy or immunotherapy treatments that target cancer cells broadly, IMGS-001 is designed to selectively target specific proteins found on the surface of cancer cells, potentially reducing side effects and improving efficacy. This targeted approach could be particularly beneficial for patients with specific types of cancer, such as ovarian, colorectal, non-small cell lung, nasopharyngeal, and head and neck/cervical cancers, where existing treatments may be less effective. Additionally, the potential for dose optimization, as explored in the trial, could further enhance its therapeutic benefits.

What evidence suggests that this trial's treatments could be effective for advanced cancer?

Research has shown that IMGS-001, a new treatment under study in this trial, has shown promise in early tests for several types of advanced cancers. These tests indicated that patients responded better and lived longer compared to those on current treatments. IMGS-001 works by blocking certain proteins, PD-L1 and PD-L2, which help cancer hide from the immune system. By blocking these proteins, the immune system can attack cancer cells more effectively. This trial includes various treatment arms for different cancers, such as ovarian and colorectal cancer, where IMGS-001 is being tested at different doses. For hard-to-treat cancers like these, this approach offers hope for better outcomes. However, more information from ongoing trials is needed to understand how well it works. ^{1 2 6 7 8}

Are You a Good Fit for This Trial?

Adults with advanced solid tumors that have worsened after standard treatments can join this trial. They must have a specific type of tumor, adequate organ function, and no recent vaccines or other cancer therapies. People with certain blood counts, liver functions, and those who haven't had severe reactions to PD-1 or PD-L1 inhibitors may qualify.

Inclusion Criteria
