The purpose of this observational research study is to follow participants who have been treated with either bel-sar or received alternate treatment (sham, standard of care therapy, etc.) while participating in a previous Aura Biosciences clinical research study to assess the long-term safety and effectiveness in these subjects. This study will collect information from procedures conducted as part of routine follow-up eye care and cancer care. Additionally, the registry will collect all adverse events, information about pregnancy and symptomatic overdose.
This early phase I trial evaluates different administration techniques (oral or intravenous) for arginine and tests the safety of giving arginine with whole brain radiation therapy in patients who have cancer that has spread from where it first started (primary site) to the brain (brain metastases). Arginine is an essential amino acid. Amino acids are the molecules that join together to form proteins in the body. Arginine supplementation has been shown to improve how brain metastases respond to radiation therapy. The optimal dosing of arginine for this purpose has not been determined. This study measures the level of arginine in the blood with oral and intravenous dosing...
ARISTOCRAT is a phase II, multi-centre, double-blind, placebo-controlled, randomised trial to compare the cannabinoid Nabiximols with placebo in patients with recurrent MGMT methylated glioblastoma (GBM) treated with temozolomide (TMZ).
Objective:Patients with asymptomatic or minimally symptomatic Stage IV EGFR-positive NSCLC with baseline intracranial metastases. Aim: To investigate the timing, efficacy and safety of radiotherapy in patients with EGFR positive brain metastases treated with armatinib alone or combined with stereotactic radiotherapy. Method: Almonertinib: specification 55mg/tablet; The dosage is 110 mg / day (2 tablets / day) orally once a day; SBRT: 3-5 doses of 27-40 Gy
The objective of this observational study is to examine the impact of augmented arterial pressure during the hemostatic phase of elective supratentorial neurosurgery. The primary inquiries it seeks to address are as follows: 1. Does an increase in systolic arterial pressure prompt a hemostatic maneuver by the neurosurgeon, and does the concomitant mean arterial pressure value influence the frequency of such interventions? 2. How often do postoperative intracranial hemorrhages occur, and how severe are they in relation to the achieved mean arterial pressure value? Participants will be enrolled during the preoperative evaluation, where their...
The goal of this study is to develop supportive diagnostic artificial intelligence algorithms to distinguish melanoma from nevi or other benign pigmented skin lesions, especially in younger patients (below the age of 30). The main goals it aims to achieve are: - development of an algorithm based on dermatoscopic images, targeting skin cancer screening in vulnerable populations - development of another algorithm based on histological images, intended to be used by pathologists on lesions that are still suspicious of melanoma after dermatologic assessment - implementation of explainability methods to enable the user to better comprehend the ...
The goal of this clinical trial is to learn if allogeneic CAR-T cells can treat patients with advanced gliomas. The main questions it aims to answer are: Evaluate the safety of allogeneic CAR-T cells in the treatment of advanced gliomas. To evaluate the effectiveness of allogeneic CAR-T cells in the treatment of advanced gliomas and to study its immunological properties in patients.
This study aims to explore the efficacy and safety of the combination therapy of utidelone and capecitabine in the treatment of brain metastases from triple-negative advanced breast cancer, and to search for systemic treatment for brain metastases from triple-negative advanced breast cancer cases.
The purpose of this single arm, multi-national clinical trial in patients with metastatic or unresectable melanoma is to evaluate the BOR and compare it to historical data on patients on anti-PD1 treatment with pembrolizumab alone.
Arterial spin labeling (ASL) is a non-invasive MRI technique that could help the radiologists to distinguish brain metastasis progression versus radionecrosis following gamma-knife treatment. The primary target of the study is to establish the diagnostic performances (specificity, sensitivity) of quantitative measures of ASL in brain metastases suspected of progression/radionecrosis after GK treatment
