Active clinical trials for "Neoplasm Metastasis"

The primary objective is to patient-reported Quality of Life related to complete control of Radiation Induced Nausea and Vomiting (RINV) between standard palliative radiotherapy and VMAT. Secondarily, we will assess rate of complete control of RINV. However, the investigators hypothesize that there will be no difference in pain response between the two arms, because they are receiving the same dose.

This will be a phase II trial testing if the combination of stereotactic ablative body radiotherapy (SABR) and L19-IL2 improve the progression-free survival in patients with limited metastatic non-small cell lung cancer (NSCLC). The trial consists of one cohort with two arms; C-arm and an E-arm. Patients with oligometastatic disease will receive SABR to minimal 1 and max all metastatic sites (max 5 sites irradiated) and patients with diffuse metastatic lesions (6 to max 10) will receive radiotherapy to max 5 sites. In the experimental arm, immunotherapy will be given after irradiation.

In patients with a limited oligometastatic burden (cancer has spread but is not yet considered metastatic), emerging evidence suggests that treatment of all sites of disease with ablative therapies can improve patient outcomes, including overall- and progression-free survival. The application of Stereotactic Ablative Radiotherapy (SABR) for patients with 4-10 metastatic deposits appears promising, yet it is unclear if all patients with greater than 3 oligometastatic lesions benefit from ablative therapies in terms of improved Overall Survival (OS), Progression Free Survival (PFS), or quality of life. The purpose of this study is to assess the impact of SABR, compared to standard of care treatment, on overall survival, oncologic outcomes, and quality of life in patients with a controlled primary tumor and 4-10 metastatic lesions.

In this study, the safety and preliminary efficacy of GNC-038 in patients with r relapsed or refractory primary central nervous system lymphoma (PCNSL) and relapsed or refractory secondary central nervous system lymphoma (SCNSL) will be investigated to assess the dose-limiting toxicity (DLT), maximum tolerated dose (MTD) or maximum administered dose (MAD) for MTD is not reached of GNC-038. The recommended dose for phase II (RP2D) clinical study will also be determined.

The incidence of colorectal cancer liver metastasis is high and the prognosis is poor. Improving the treatment effect of colorectal cancer liver metastasis is the key to improving the prognosis of colorectal cancer patients. Rigofenib is one of the standard third-line treatments for advanced colorectal cancer, but has limited efficacy. Immune checkpoint inhibitors (PD-L1 monoclonal antibody, PD-1 monoclonal antibody) have achieved good results in the treatment of various malignant tumors. In a mouse transplant tumor model of colorectal cancer, regorafenib combined with PD-1 monoclonal antibody treatment significantly improved the antitumor activity, but the efficacy rate in clinical studies was not very high, especially for liver metastases. Radiofrequency ablation (RFA) is one of the common methods for the treatment of liver metastases. RFA may improve the immune microenvironment and the efficacy of immunotherapy,and the purpose of this trial is to explore the efficacy and safety of rigofenib and terepliumab combined with RFA in patients with refractory colorectal cancer liver metastasis.

This study is a single-arm, multicenter, open-labeled clinical study of UTD1 combined with Capecitabine in metastatic HER2-negative breast cancaner patients with brain metastases. This study aims to evaluate the efficacy and safety of UDT1 combined with capecitabine in metastatic HER2-negative breast cancer patients with brain metastases.

The purpose of this study is to evaluate the safety and efficacy of Keynatinib capsules in patients with advanced non-small cell lung cancer (NSCLC) with brain metastasis or progression of brain metastasis after treatment with EGFR inhibitors. As well as, to evaluate the penetration rate of Keynatinib in the Blood-Brain Barrier (BBB) and its PK characteristics, and the relationship between exposure levels with efficacy and safety.

Brain metastases are the most common brain tumors in adults. It is estimated that around 10-30% of cancer patients would develop brain metastases during the course of their illness. Whole brain radiotherapy (WBRT) is the treatment of choice for the majority of patients with brain metastases. WBRT yields high radiologic response rate (27~56%) and is effective in rapid palliation of neurologic symptoms as well as prolongs time to neurocognitive function decline caused by intracranial lesions. By using conventional fractionation, more than one- third of patients developed late neurocognitive toxicity while memory impairment was the most common symptom. The incidence is even higher when a formal and sensitive neurocognitive assessment was prospectively evaluated. With more long-term survivors nowadays, it has become increasingly important to minimize neurocognitive function decline and maintain quality of life in patients with brain metastasis. The function of hippocampus is cooperation in learning, consolidation and retrieval of information and essential for formation of new memories. Bilateral and unilateral radiation injury of the hippocampus is known to alter learning and memory formation. Several preclinical studies support the hypothesis of hippocampus-mediated cognitive dysfunction by ionizing radiation. Clinical studies show increase in radiation dose to hippocampus is associated with subsequent neurocognitive function impairment in adult and pediatric patients. Furthermore, the result of phase III randomized trials suggested hippocampal avoidance plus Memantine significantly reduce the risk of neurocognitive impairment at 6 months from 68.2% in control arm with standard WBRT to 59.5% in experimental arm. In the investigator's prior investigation, patients received conformal WBRT with bilateral hippocampal avoidance also had significant less declines in verbal memory at 6 months. Previous studies showed the right and left hippocampus exert different neurocognitive functions. Several retrospective studies also demonstrated that the radiation dose to the left hippocampus is more related to neurocognitive impairment. Planning study and investigation showed that by avoiding the left hippocampus alone, the radiation dose to the spared unilateral hippocampus is further decreased. In present study, a single blind randomized phase II trial is designed to investigate the effectiveness of neurocognitive function preservation using conformal WBRT with bilateral or unilateral hippocampal avoidance and memantine.

This study is a prospective, single-arm, phase II clinical study to evaluate the efficacy and safety of Tislelizumab Plus Chemotherapy in patients with squamous NSCLC with brain metastases who had not previously received systemic therapy.

Tyrosine Kinase Inhibitors (TKIs) especially higher generation TKI have higher CNS penetration rates and have shown favorable response rates in brain metastases. Brain radiotherapy/surgery is the standard treatment in brain metastases especially symptomatic metastases, however, the role of local treatment especially in driver mutation-positive non-small cell lung cancer with asymptomatic brain metastases is being questioned given their potential side effects. No randomized trial has shown the superiority of early vs delayed cranial RT in asymptomatic BM of driver mutated NSCLC.
