Filter by:This study will test the safety of the study drug, GDC-0084, in combination with radiation therapy in people who have solid tumor brain metastases or leptomeningeal metastases. All participants will have cancer with a PIK3CA mutation. The researchers will test increasing doses of GDC-0084 to find the highest dose that causes few or mild side effects in participants. The study will also try to find out if the combination of the study drug with radiation is effective against participants' cancer.
This clinical trial was designed to investigate the efficiency and toxicity of tomotherapy for leptomeningeal metastases.
Leptomeningeal metastasis (LM) is a devastating and terminal complication of advanced non-small-cell lung cancer (NSCLC), especially in patients harboring epidermal growth factor receptor (EGFR) mutations. Osimertinib is an oral,third-generation, irreversible epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) that selectively inhibits both EGFR-TKI-sensitizing and EGFR T790M resistance mutations .AURA I/II study and other preclinical study suggested that Osimertinib exhibited a better blood-brain barrier(BBB) penetration than the other EGFR-TKIs (gefitinib, erlotinib, or afatinib).The BLOOM 、AURA and FLURA study demonstrated that osimertinib showed encouraging activity and manageable tolerability in pretreated EGFR-mutant NSCLC patients with LM. Bevacizumab is a monoclonal antibody against vascular endothelial growth factor (VEGF). Animal study and autopsy specimens showed that VEGF is an essential factor in LM. Recently study showed EGFR-TKIs plus bevacizumab prolonged PFS and OS in patients with EGFR-mutant NSCLC and multiple brain mteastasis when compared with EGFR-TKIs alone. Howerver osimertinib combined with bevacizumab could benefit patients with LM from EGFR- mutant NSCLC remains undetermined. Therefore, the purpose of the study is to evaluate the safety and efficacy of osimertinib combined with bevacizumab for EGFR- mutant non-small cell lung cancer with leptomeningeal metastasis
This is a multicenter, interventional, prospective study among breast cancer patients with a suspicion of metastatic meningitis. The current study aims to assess the use of proteomic profile issued from cerebrospinal fluid microvesicles for diagnosis of leptomeningeal metastases.
This study uses bi-specific antibody (HER2Bi) armed activated T-cells (HER2 BATs) to target breast cancer cells that have metastasized to the membranes surrounding the brain and spinal cord. This is known as leptomeningeal metastases. Two doses will be evaluated in order to determine a safe dose. Study treatment includes a test dose of HER2 BATs followed by 8 weekly infusions of HER2 BATs at the assigned dose level. Before, during and after study treatment, participants will be monitored objectively by brain MRIs and clinically through physical and neurological exams, and blood and cerebrospinal fluid will be collected to evaluate immune responses.
This is an open-label Phase 3 study to see if ANG1005 can prolong survival compared to a Physician Best Choice control in HER2-negative breast cancer patients with newly diagnosed leptomeningeal disease and previously treated brain metastases.
The purpose of this study is to find the safest and most effective dose for delivering proton beam to the space containing CSF, brain, and spinal cord, in treating leptomeningeal metastases. The researchers think that using proton beam radiation to treat the space containing CSF, brain, and spinal cord, instead of treating only the areas where the metastasized tumor cells are causing symptoms, would improve the treatment of this disease.
Intrathecal chemotherapy is one of the most important treatment modalities for leptomeningeal metastasis of solid tumors. In the previous retrospective study, it has been proved that concurrent radiotherapy and intrathecal methotrexate for leptomeningeal metastasis from solid tumors with adverse prognostic factors showed great effectiveness and safety. The preliminary results of investigators' current prospective clinical study (Involved-field Radiotherapy Combined With Concurrent Intrathecal-methotrexate Versus Intrathecal-Ara-C for Leptomeningeal Metastases From Solid Tumor: A Randomized Phase II Clinical Trial. ClinicalTrials.gov identification number: NCT03082144) also showed that the regimen of concurrent intrathecal chemotherapy and radiotherapy may serve as an optimal therapeutic option for treatment of leptomeningeal metastases from solid tumors. Pemetrexed is a newer multitargeted antifolate which has shown activity in various tumors. In investigators' current study (Intrathecal Pemetrexed for Recurrent Leptomeningeal Metastasis From Non-small Cell Lung Cancer: A Prospective Pilot Clinical Trial. ClinicalTrials.gov identification number: NCT03101579), the regimen of intrathecal pemetrexed with folic acid and vitamin B12 supplementation may provide higher effectiveness and safety for recurrent leptomeningeal metastasis from non-small cell lung cancer. Therefore, the purpose of the study is to evaluate the tolerability, safety and effectiveness of intrathecal pemetrexed combined with involved-field radiotherapy as the first line treatment in patients with leptomeningeal metastases from malignant solid tumors.
Children with a neuroblastoma diagnose and central nervous system (CNS)/leptomeningeal metastases will be given up to 2 rounds of intracerebroventricular treatment with a radiolabelled monoclonal antibody, 131I-omburtamab to evaluate efficacy and safety
AZD9291 is an oral potent irreversible EGFR TKI selective for sensitizing EGFR mutation and T790M resistance mutation but sparing wild-type EGFR. Preclinical studies indicate that AZD9291 has significant exposure in the brain and activity against EGFR mutant brain metastasis. In addition, anti-tumor activities of AZD9291 in patients with advanced stage EGFR mutant NSCLC including patients with brain metastasis have been reported in an ongoing Phase I study. More recently, AZD9291 at a dose of 160mg also showed promising efficacy in heavily pre-treated patients with leptomeningeal disease from EGFR mutant NSCLC. Among 11 evaluable for response, 6 patients had LM imaging improvement and 3 out of 7 patients with abnormal neurological exam at baseline had symptomatic improvement. Compared to AZD9291, other 3rd generation EGFR TKIs, rociletinib or HM61713 has not been reported to be effective in most of CNS disease of NSCLC. Further, previous studies with AZD9291 showed anecdotal case series or undetermined for T790M mutation status, indicating more systematic study is warranted. Based on these data, the investigators are going to conduct phase II study of AZD9291 in NSCLC patients harboring T790M mutation who failed EGFR TKIs and brain and/or leptomeningeal metastasis.
