Active clinical trials for "Neoplasm Metastasis"

For patients with 1-6 intraparenchymal brain metastases from various primary histologies (except for melanoma), stereotactic radiosurgery (administered upfront or concurrently) or complete surgical resection with neural stem cell (NSC)-preserving whole-brain radiotherapy (WBRT) results in improved neurocognitive profile over standard WBRT. The goal of this study is to assess feasibility of this treatment approach.

Primary Objective: This trial is elaborating a model for rapidly predicting (day 21) the response to monoclonal antibodies anti-EGFR and anti-VEGF (cetuximab and bevacizumab) based on biological markers and/or functional imaging. The response to treatment is evaluated by the conventional method after 2 months (Response Evaluation Criteria in Solid Tumors [RECIST] criteria). Secondary Objectives: This trial is also analyzing the correlation between the magnitude of response to treatment at 2 months (stabilization or objective response, RECIST criteria) and that of response observed after 6 months of treatment. The organisational objective is to develop a tumour bank of metastatic colorectal cancer. Population: The population includes 252 male and female patients with metastatic colorectal cancer justifying the use of cetuximab or bevacizumab, with no heart disease. Techniques: Computed tomography (CT scan), functional imaging (ultrasound with SonoVue); molecular imaging (positron emission tomography [PET] with fluorodeoxyglucose F18 [18-FDG]); and biology and pathology on microbiopsy of liver metastasis are used. Outcome Criteria: The primary outcome is response to treatment with monoclonal antibodies according to RECIST criteria at two months. Studied Factors: Radiology: CT scan: RECIST criteria (gold standard); Ultrasound with SonoVue injection: 1 representative target (delay of contrast appearance, peak of rising, curve of increase and decrease of the signal, area under the curve, time of average transit). Nuclear Medicine: PET scan and 18-FDG (standard uptake values [SUV]) Molecular Characterization of Tumors: p53 status; microsatellite instability (MSI) status; expression of oncogenes; EGFR status; VEGF status; determination of FcgammaRIIIA polymorphisms Statistics: Descriptive analyses; Analysis of the appropriate threshold to measure: response to treatment by an ultrasound with SonoVue and by PET scan; correlation between response predicted by the ultrasound with SonoVue and the PET; conventional morphological CT at 2 months Analysis of prognostic factors: Evaluation of the role of each prognostic factor (pathology and imaging) on response to treatment; Multivariate analysis of prognostic factors; Analysis of the prognostic power of early response at 2 months on the response observed after 6 months of treatment.

Studies of PEG-paclitaxel have been terminated

This will be the first trial testing the feasibility of working simultaneously with the two fluorescent dyes ICG and SGM-101 in 10 patients with colorectal metastases.

This pilot study is a randomized, open-label, 2-arm active-controlled phase II clinical trial conducted at a single study site (UAMS). Subjects will be randomized to one of the 2 treatment arms and stratified by size of index lesion and number of brain metastases. The investigators will prospectively compare preoperative (neoadjuvant) SRS/SRT to postoperative (adjuvant) SRS/SRT in patients undergoing surgical resection for brain metastases. The investigators hypothesize that neoadjuvant SRS/SRT prior to surgical resection of brain metastases will result in improved freedom from Central Nervous System (CNS) events when compared to adjuvant SRS/SRT after surgical resection.

The goal of this diagnostic intervention clinical trial is to compare 18F-Fluciclovine uptake within brain lesions over 60 minutes compared with standard of care positive histology confirmation or confirmation MRI images. The main questions it aims to answer are: What are the dynamics of 18F-Fluciclovine update within a non-treated metastatic brain lesion over 60 minutes? What are the dynamics of 18F-fluciclovine update within recently treated metastatic brain lesions? What is the potential use of 18F-Fluciclovine in delineating true local progression from radionecrosis in patients with clinical uncertainty of indeterminate MRI? Participants will undergo an 18F-fluciclovine head PET/CT scan prior to treatment for brain metastatic lesion(s). The study will characterize uptake dynamic PET images over 60 minutes. Uptake within the lesions and the benign brain parenchyma will be plotted on a time activity curve for 60 mins. Patients will undergo a second 18F-fluciclovine PET/CT to evaluate 18F-fluciclovine uptake in treated lesions over 60 minutes. This will be offered concurrently with the post-procedure standard of care (SOC) MRI to evaluate post-treatment changes. Uptake within the lesions and the benign brain parenchyma will be plotted on a 60 min time activity curve. Results will be compared to the pre-treatment baseline images. A third 18F-fluciclovine PET/CT will be offered to evaluate post radiation changes necrosis from recurrence, for up to 10 patients in our cohort who are under clinical surveillance (up to three years surveillance) and developed MRI evidence of either true progression or radionecrosis with clinical uncertainty after stereotactic radiosurgery. The initial 18F-fluciclovine PET/CT will serve as a baseline PET/CT scan. This will be compared to post procedural histological confirmation.

Nivolumab releases the inhibition of the immune system against human cancers. Dramatic and sustained activity has been observed in advanced lung cancer. Ablation may stimulate the immune system by exposing new tumor antigens. Since tumors that express PD-L1 may be more likely to respond to nivolumab, if ablation increases PD-L1 expression (which has not been studied) this treatment may enhance the activity of nivolumab at both the treated site and in other, non-treated, tumors. Ablation is already an FDA approved treatment for cancer. Nivolumab was recently FDA approved for second line treatment of advanced squamous cell NSCLC. The goal of the study will be to determine if the combination of nivolumab and ablation has higher systemic activity than previously reported with nivolumab alone.

The goal of this study is to find the maximum dose of a drug, temozolomide, that can safely be given to subjects with brain tumors. Past studies showed that the maximum dose of temozolomide was limited by low blood counts. The investigators will use blood stem cells collected from bone marrow to help subjects recover their blood counts, a procedure called autologous stem cell transplant or stem cell rescue. This way, the investigators expect to be able to safely deliver very high doses of temozolomide. This study is only available at Tufts Medical Center.

The purpose of this study is to determine if administering temozolomide after completion of stereotactic radiosurgery helps control existing brain metastases and prevents the developement of new brain metastases.

The purpose of this study is to determine pain control rate (Percentage of patients in each arm that achieve pain control) at the treated site(s) at 1 month, 2-4 months and 5-6 months post-treatment.
