What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new treatment combining ipatasertib (a potential cancer therapy) and docetaxel for individuals with advanced non-small cell lung cancer (NSCLC) who have not benefited from first-line immunotherapy. Researchers aim to determine if this combination can aid those resistant to standard treatments. Participants should have previously tried immunotherapy without success and lack specific genetic mutations that other therapies could target. As a Phase 2 trial, the 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 protocol does not specify if you must stop taking your current medications. However, you cannot be on other cancer treatments or certain medications that affect liver enzymes 14 days before and during the study.

Is there any evidence suggesting that this treatment is likely to be safe for humans?

Research shows that ipatasertib, when combined with chemotherapy drugs like docetaxel, has been studied for safety in treating various cancers. Studies indicate that ipatasertib can be safely paired with common chemotherapy treatments.

Earlier research suggests that using ipatasertib with docetaxel may improve outcomes for cancer patients. However, researchers are still collecting safety data to understand how well patients tolerate this combination.

This treatment is currently in a phase 2 trial, indicating that ipatasertib has already passed initial safety tests. This phase focuses more on the combination's effectiveness for patients and continues to monitor its safety.

While promising evidence exists, it's important to note that, like many cancer treatments, some patients may experience side effects. The specific side effects and their frequency are still under study. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard treatments for non-small cell lung cancer, which often include chemotherapy and targeted therapies like EGFR inhibitors, Ipatasertib targets a different pathway. Ipatasertib is unique because it specifically inhibits the Akt protein, a key player in the PI3K/Akt signaling pathway that often drives cancer growth. Researchers are excited about this treatment because targeting this pathway could offer a new approach to halting cancer progression, especially in patients who have developed resistance to other treatments. Additionally, combining Ipatasertib with Docetaxel, a chemotherapy drug, might enhance the overall effectiveness by attacking the cancer from multiple angles.

What evidence suggests that ipatasertib combined with docetaxel might be an effective treatment for non-small cell lung cancer?

Research has shown that using ipatasertib with docetaxel to treat non-small cell lung cancer (NSCLC) appears promising. In this trial, participants will receive a combination of ipatasertib and docetaxel. Studies have found that ipatasertib alone helped stabilize cancer in more than half of the patients, preventing progression during treatment. Ipatasertib blocks a protein called AKT, which aids cancer growth. By inhibiting this protein, ipatasertib can enhance the effectiveness of chemotherapy drugs like docetaxel. This combination aims to assist patients who haven't responded to other treatments. ^{1 5 6 7 8}
