What is the purpose of this trial?

This trial explores whether the experimental drug AZD5335, alone or combined with other cancer-fighting drugs, is safe and effective for individuals with advanced tumors. Participants will receive AZD5335 either by itself or with other treatments such as Saruparib (AZD5305), Bevacizumab, Carboplatin, or AZD9574, depending on their trial group. The trial seeks individuals with advanced solid tumors that have previously been treated but have not responded well or require a new treatment option. Those with a measurable disease who consider a clinical trial as their next best step might find this trial suitable. As a Phase 1 and Phase 2 trial, the research focuses on understanding how the treatment works in people and measuring its effectiveness in an initial group.

Do I need to stop my current medications to join the trial?

The trial information does not clearly specify if you need to stop your current medications. However, it mentions that treatment with certain medications requires adequate 'washout periods' (time without taking certain medications) before starting the study treatment. 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 shows that AZD5335, when used alone, is generally safe and well-tolerated. Early studies found no dose-limiting toxicities, indicating patients can handle increasing doses without severe side effects. No treatment-related deaths have occurred, and the highest safe dose remains unidentified.

When combined with other drugs like Saruparib, Bevacizumab, Carboplatin, and AZD9574, AZD5335 also appears safe and manageable. Reports indicate that adding AZD5335 to these drugs doesn't significantly increase unwanted side effects. Serious issues, such as severe illness or death, were rare, occurring in less than 2% of patients.

The trials are in early stages, meaning these combinations have been tested in smaller groups. As a result, the treatments are still under evaluation to ensure safety for a larger population. However, these early results are promising for those considering participation in such trials. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Unlike the standard treatments for cancer, which often include chemotherapy and targeted therapies like bevacizumab, AZD5335 is unique because it can be combined with various other agents to potentially enhance its effectiveness. Researchers are excited about AZD5335 because it is used in multiple combinations, such as with saruparib, bevacizumab, carboplatin, and AZD9574, offering a tailored approach to treatment. This flexibility allows it to target cancer cells in different ways, possibly overcoming resistance to traditional treatments. Additionally, AZD5335 may work through novel mechanisms that could make it more effective for patients who have not responded well to existing options. This innovative approach could lead to improved outcomes and new treatment paradigms in oncology.

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

Research has shown that AZD5335 may help treat various types of cancer. In one study, 25% of patients experienced a reduction in their cancer, though it did not completely disappear. The treatment proved particularly effective in certain cancers: 50% of cervical cancer patients, 57.5% of endometrial cancer patients, and 45% of ovarian cancer patients saw a reduction in their cancer. In this trial, participants may receive AZD5335 combined with other drugs like Saruparib or Bevacizumab, which have shown even better results in fighting tumors. For instance, combining AZD5335 with Saruparib demonstrated improved outcomes in some cancer cells during lab studies. Overall, AZD5335's potential to treat various cancers and its effectiveness when used with other treatments make it a promising option for advanced cancers. ^{1 2 3 6 7}
