Targeted Therapy for Brain Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests how well genetic testing can guide treatment for patients with brain cancer that originated elsewhere and spread to the brain. It targets patients with specific gene mutations, such as NTRK, ROS1, CDK, PI3K, or KRAS G12C. The trial uses medications aimed at these mutations, potentially stopping tumor growth by blocking enzymes that aid cell growth. People with brain tumors featuring these genetic changes, who have not responded to other treatments, might be suitable for this study. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, offering a chance to benefit from targeted therapies.
Will I have to stop taking my current medications?
The trial requires a washout period for certain medications. You must stop chemotherapy at least 14 days before joining the study, and for the abemaciclib arm, a 21-day washout is needed. If you're on strong CYP3A4 inhibitors or inducers, you must stop them 14 days before starting the trial. For the entrectinib arm, you cannot use certain stomach acid medications.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Previous studies have generally shown that abemaciclib is well-tolerated. Some patients experienced side effects, but these were mostly manageable. Common side effects included fatigue and diarrhea.
Research on entrectinib has shown promising safety results. For patients with brain tumors, it proved effective without causing many serious side effects. Some patients reported mild to moderate side effects, such as dizziness and nausea.
Paxalisib has also undergone safety studies. The most common side effects included high blood sugar and skin rash. However, these were similar to those of other medications, and many patients managed the treatment well.
Overall, these treatments have been tested in patients with brain tumors and have shown reasonable safety. However, like any treatment, they may have some side effects, and the experience can vary from person to person.12345Why are researchers excited about this trial's treatments?
Researchers are excited about these investigational treatments for brain cancer because they offer novel, targeted approaches that differ from traditional chemotherapy and radiation. Abemaciclib specifically targets CDK gene mutations, potentially stopping cancer cell growth more effectively. Entrectinib is designed for those with NTRK/ROS1 gene mutations, zeroing in on specific cancer-driving proteins. Paxalisib targets the PI3K pathway, which is often involved in cancer cell survival, offering a new avenue for those with PI3K gene mutations. Lastly, adagrasib focuses on the KRAS G12C mutation, a notoriously difficult target, potentially providing a breakthrough for patients with this mutation. These drugs represent a shift toward more personalized and precise cancer treatments.
What evidence suggests that this trial's treatments could be effective for brain cancer?
Research shows that abemaciclib, available to participants in Arm I of this trial, can penetrate the brain and slow tumor growth by blocking proteins called CDK 4 and CDK 6. Studies suggest it may halt the growth of high-grade gliomas, a type of brain tumor, and even shrink them in some cases. Entrectinib, offered in Arm III, has demonstrated a 61.2% success rate in patients with brain tumors, particularly those with NTRK or ROS1 gene changes. For paxalisib, studied in Arm II, research indicates it can cross into the brain and has improved survival rates in patients with glioblastoma, a severe brain cancer. These treatments target specific genetic changes, potentially stopping tumor cells from growing.12567

Are You a Good Fit for This Trial?
This trial is for patients with solid tumors that have spread to the brain, who can undergo MRI scans and haven't had recent surgery or chemotherapy. They must not be pregnant or nursing, have no uncontrolled medical issues, and not be on certain drugs affecting liver enzymes. Participants need confirmed metastatic disease in the brain from a solid tumor with specific gene alterations (NTRK, ROS1, KRAS G12C, CDK pathway or PI3K pathway) and meet other health criteria.Inclusion Criteria
