Filter by:This study is to evaluate the efficacy and safety of TY-9591 in first-line treatment of patients with EGFR-sensitive mutation-positive non-small cell lung cancer with brain metastases compared to Osimertinib.
Patients suffering from malignancies in advanced stages often develop brain metastases, which limit both the life span and the quality of life. Combining surgery and radiotherapy for resectable brain metastases is standard of care but there is a lot of controversy on which kind of radiotherapy is best suitable. Recently, first volumetric in-silico analyses point to theoretical advantages of neoadjuvant stereotactic radiotherapy of brain metastases. Special about this trial is the direct comparison between the three currently discussed radiotherapy options for resectable brain metastases: Neoadjuvant stereotactic radiotherapy, intraoperative radiotherapy and adjuvant stereotactic radiotherapy.
This trial uses multi-parametric magnetic resonance imaging (MRI) to develop and validate imaging risk score to predict radiation necrosis in participants with brain metastasis treated with radiation therapy. Diagnostic procedures, such as multi-parametric magnetic resonance imaging (MRI), may improve the ability to diagnose radiation necrosis early and help establish treatment strategies.
The purpose of the study is to determine in brain metastases and according to feasibility in liquid biopsies: - Molecular alterations including in particular mutations, amplifications, Copy number gene variants and fusion transcripts identified by high-throughput sequencing; - The rate of variation either in gain or in loss of expression of the different messenger Ribonucleic Acids by analysis of the transcriptome; - Epigenetic alterations by methylation of deoxyribonucleic acid clusters by methylome chips.
The purpose of this study was to investigate the efficacy and safety of Cadonilimab combined with bevacizumab and chemotherapy for advanced non-squamous NSCLC with untreated brain metastases. Cadonilimab is a bispecific antibody (BsAb), which can bind PD-1 and CTLA-4 at the same time with high affinity. It is a new tumor immunotherapy drug with tetravalent structure and short half-life. It has shown less toxicity than anti-PD-1 and anti-CTLA-4 antibodies in monkey toxicity studies. These characteristics make the application of Cadonilimab in tumor subjects may have better efficacy and safety. AK104-207 is an open, multicenter, phase Ib/II clinical study, which aims to evaluate the effectiveness and safety of Cadonilimab combined with chemotherapy as the first-line treatment for locally advanced or metastatic non-small cell lung cancer that cannot be operated and cannot receive radical concurrent/sequential radiotherapy and chemotherapy. As of August 1, 2022, 19 subjects who can evaluate non-squamous NSCLC (cohort B), ORR is 63.2%, DCR is 100%, median PFS is 13.34 months (7.36, NE), median OS is not reached, and 12-month OS rate is 76.0% (95% CI 48.0-90.3). In PD-L1 positive patients (n=9), ORR was 55.6% and DCR was 100%. In PD-L1 negative patients (n=7), ORR was 85.7% and DCR was 100%. In view of the early curative effect of Cadonilimab in NSCLC single drug or combination therapy and the encouraging research results of PD-1 inhibitor combined with CTLA-4 double immune combination therapy, it is expected that Cadonilimab combined with bevacizumab and chemotherapy will achieve good curative effect in NSCLC patients with brain metastasis.
A multicenter, single-arm, open study to evaluate the safety and efficacy of Serplulimab in combination with bevacizumab and first-line chemotherapy in driver negative non-squamous NSCLC patients with brain metastases
To determine the safety and efficacy of using the drug azeliragon combined with stereotactic radiosurgery. Specifically, to determine if this combination will lead to improved response in the brain (tumor shrinking in size) and overall tumor control (how long tumor remains controlled).
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 or BRAF mutations, advanced/metastatic melanoma harboring BRAF or NRAS mutations, histiocytic neoplasms harboring BRAF 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.
This is a prospective, multicenter, randomized, controlled clinical study of NSCLC patients with intracranial oligo-metastatic EGFR-sensitive mutations treated with EGFR-TKI Almonertinib , according to the implementation time of brain radiotherapy. Patients were randomly divided into two groups, experimental group (early intervention group of brain radiotherapy) : the brain radiotherapy started within 1 month of TKI treatment, the brain radiotherapy here specifically refers to stereotactic radiotherapy; Control group (brain radiotherapy late intervention group) : Brain radiotherapy was given within 3 months after brain progression during TKI treatment. The differences in OS,iPFS, PFS, iORR, safety, neurocognitive function and quality of life between the two groups were compared.
Contrast-enhanced magnetic resonance imaging is the most widely used examination for detecting the presence of brain metastasis. Functional sequences such as perfusion weighted imaging makes it possible to differentiate tumor recurrence from cerebral radionecrosis. However, this imaging technique may exhibit limitations, especially for brain lesions consisting of a mixture of necrotic tissue and tumor progression or depending on the location of the lesion in the brain. The use of 18F-DOPA PET is another option available to oncologists. Many studies on gliomas showed the superiority of this imaging technique over contrast-enhanced MRI. However, this imaging solution has been very poorly studied for brain metastases. The new PET technology equiped with silicon detectors makes it possible to obtain greater sensitivities than those of previous generations. It also make possible to obtain images in very short acquisition times. After injection, the hardware allows to obtain the perfusion kinetics of the lesion thanks to a very short temporal sampling (i.e. three seconds). The main objective of this pilot study is to evaluate the association between early activity measurements (< 4 minutes post-injection) of 18F-FDOPA in PET and the differential diagnosis between radionecrosis and recurrence of cerebral metastases treated by radiotherapy.
