DSP107 + Atezolizumab for Colorectal Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores whether a new combination of medicines, DSP107 (an experimental treatment) and atezolizumab (an immunotherapy drug), can more effectively treat advanced microsatellite stable colorectal cancer (a type of cancer with few genetic changes) compared to the existing drug fruquintinib. Participants will be randomly assigned to receive either the new combination or fruquintinib to evaluate cancer response and treatment tolerance. The trial seeks individuals whose cancer has progressed despite previous treatments and who have a type of colorectal cancer that cannot be surgically removed. As a Phase 2 trial, this research focuses on assessing the treatment's effectiveness in an initial, smaller group of people.
Will I have to stop taking my current medications?
The trial information does not clearly state if you need to stop your current medications, but it mentions that recent treatment with certain therapies, including some anticancer treatments and immunomodulating therapies, may exclude you from participating. It's best to discuss your specific medications with the trial team.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that the combination of DSP107 and atezolizumab is generally safe for people. A recent study found this combination safe for patients with advanced colorectal cancer, with no serious side effects affecting blood cells, the liver, or other organs. Another study confirmed that both DSP107 alone and with atezolizumab were well-tolerated, with no major safety concerns. Overall, the evidence suggests that this treatment is safe for those considering participation in this clinical trial.12345
Why are researchers excited about this trial's treatments?
Researchers are excited about the DSP107 and Atezolizumab combination for colorectal cancer because it offers a novel approach compared to standard treatments like chemotherapy and those targeting specific cancer pathways. DSP107 is unique because it targets CD47, a protein that helps cancer cells evade the immune system. By combining this with Atezolizumab, an immunotherapy that boosts the body's natural defenses against cancer, the treatment has the potential to more effectively engage the immune system in fighting the tumor. This dual approach could offer improved outcomes for patients who might not respond well to existing therapies.
What evidence suggests that this trial's treatments could be effective for advanced colorectal cancer?
Research has shown that combining DSP107 and atezolizumab, which participants in this trial may receive, may help treat advanced colorectal cancer. This combination has been found to shrink or control tumor growth. In patients with a type of colorectal cancer called MSS, particularly those whose cancer has spread to the liver, the treatment stopped or reduced cancer growth in 57% of cases. More than half of the patients experienced a halt or reduction in their cancer's growth for a period of time. Early results suggest this treatment could benefit those who haven't had success with other treatments. Another treatment arm in this trial involves Fruquintinib, administered as an active comparator.12346
