5 Clinical Trials for Various Conditions
Hippocampal-avoidance whole brain radiation therapy (HA-WBRT) limits radiation dose to the hippocampal-avoidance region while still delivering therapeutic doses of radiation to the whole brain. When used in addition to prophylactic memantine, this technique has been shown to better preserve cognitive function in patients with brain metastases outside of the hippocampal-avoidance region with no difference in intracranial progression-free and overall survival. However, HA-WBRT requires considerably longer planning time when compared to conventional WBRT (5-10 business days, compared to next-day), and studies have shown that brain metastases can grow in as rapidly as one week. A proposed solution for quicker initiation of HA-WBRT is the use of simulation-free radiation treatment planning, in which pre-existing diagnostic images are used to generate the radiation treatment plan (as opposed to acquiring planning-specific image sets). This will be paired with the use of artificial intelligence (AI)-assisted semi-automated planning using the FDA-approved treatment planning system called Ethos Therapy. The investigators have developed an institutional HA-WBRT auto-planning template, which has been retrospectively validated for the creation of plans that are compliant with the gold standard NRG Oncology CC001 clinical trial and are dosimetrically comparable to traditional HA-WBRT plans. Semi-automated plans will be constructed using diagnostic imaging, which will be refined as needed (adjustments for difference in gross head positioning between diagnostic imaging and radiation treatment positioning, etc.) while the patient is on the treatment table at fraction one using adaptive radiation planning. Adaptive radiotherapy is standard-of-care practice for other disease sites. The purpose of this study is to demonstrate the feasibility and safety of a simulation-free workflow for HA-WBRT that is AI-assisted and semi-automated.
This clinical trial studies the different types of investigational imaging techniques called sequences during magnetic resonance imaging (MRI) of the head before and after radiation therapy in patients with cancer that has spread to the brain (intracranial metastases). This clinical trial also compares these new techniques with standard MRI imaging to see if sequences provide better images. Diagnostic procedures, such as MRI, may help find and diagnose solid organ cancer and find out how far the disease has spread.
This trial studies how well dual energy computed tomography (DECT) works in imaging patients with solid organ cancer that has spread to the brain. Imaging techniques, such as DECT, may help find and diagnose tumor cells and find out how far the tumor cells have spread in the brain.
This phase I trial is studying the side effects and best dose of bevacizumab and cediranib maleate in treating patients with metastatic or unresectable solid tumor, lymphoma, intracranial glioblastoma, gliosarcoma or anaplastic astrocytoma. Monoclonal antibodies, such as bevacizumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Cediranib maleate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Bevacizumab and cediranib maleate may also stop the growth of cancer cells by blocking blood flow to the cancer. Giving bevacizumab together with cediranib maleate may kill more cancer cells.
BDTX-4933-101 is a first-in-human, open-label, Phase 1 dose escalation and an expansion cohort study designed to evaluate the safety and tolerability, maximum tolerated dose (MTD) and the preliminary recommended Phase 2 dose (RP2D), and antitumor activity of BDTX-4933. The study population for the Dose Escalation part of the study comprises adults with recurrent advanced/metastatic non-small cell lung cancer (NSCLC) harboring KRAS non-G12C mutations, BRAF, or CRAF (RAF1) mutations, advanced/metastatic melanoma harboring BRAF or NRAS mutations, histiocytic neoplasms harboring BRAF, CRAF, or NRAS mutations, and other solid tumors harboring BRAF mutations. The study population for the Dose Expansion part of the study comprises adults with recurrent advanced/metastatic NSCLC harboring KRAS non-G12C mutations. All patients will self-administer BDTX-4933 orally in 28-day cycles until disease progression, toxicity, withdrawal of consent, or termination of the study.
