Active clinical trials for "Neoplasm Metastasis"

This research is being done to study the efficacy and safety of unrelated umbilical cord blood stem cell microtransplantation combined with azacitidine(AZA) based treatment for advanced myelodysplastic syndromes(MDS), Chronic myelomonocytic leukemia-2(CMML-2) and secondary acute myeloid leukemia(sAML). The study protocol involved unrelated umbilical cord blood stem cell combined with azacitidine based treatment, which including azacitidine alone and azacitidine plus a targeted agent or chemotherapy agent.

This is a Phase 1,open-label, multi-center, first-in-human, 2-part (Part 1: dose escalation and Part 2: expansion) study, evaluating multiple doses and schedules of intravenously (IV) administered NTX-1088, with or without pembrolizumab, in patients with advanced solid malignancies (i.e., locally advanced or metastatic).

This is an open-labe Phase I study of BPI-28592 for the treatment of patients with solid tumors

The purpose of this study is to learn whether adding abemaciclib to abiraterone plus prednisone prolongs the time before prostate cancer gets worse. Participation may last approximately 60 months.

The TEMPLE study is a single-center prospective phase Ib and II trial to determine the safety, tolerability and efficacy of Atezolizumab given in combination with thiopurine therapy (6-mercaptopurine and 6-thioguanine) in patients with advanced and/or metastatic solid tumors with an intermediate tumor mutational burden. Maximum tolerated dose (MTD) and/or recommended phase II dose (RP2D) will be determined in a single armed, open label phase Ib trial with a fixed dose of Atezolizumab in combination with thiopurine therapy with a dose-limiting toxicity (DLT) period of 4 weeks. A total of 27-39 patients will be enrolled in the TEMPLE study. Phase Ib will enroll 3-18 patients depending on the number of DLTs and need for dose de-escalation. Data from patients treated in the phase Ib study at RP2D will be included when assessing endpoints in the phase II part of the study. Phase II will enroll a total of 27 patients (including 3-6 patients treated at RP2D in the phase I part of the trial) in a Simon's 2 stage design (13 in stage 1 and 14 in stage 2).

Whole brain radiotherapy (WBRT) has long been a practical and effective therapeutic modality for various settings of management in radiation oncology. For example, the indications for WBRT should include brain metastasis or metastases, the setting of prophylactic cranial irradiation (PCI) used mainly for patients with limited-stage small cell lung cancer, and even some patients with extensive-stage small cell lung cancer. The rationales for WBRT are essentially based on that it can target both microscopic and gross intracranial disease. In addition to providing rapid alleviation of neurologic symptoms and enhanced intracranial disease control, WBRT might also prolong the time to develop neurocognitive function (NCF) decline. However, paradoxically NCF decline can also occur due to a sequel of WBRT. In terms of the time course of WBRT-induced NCF decline, it might vary considerably according to the specific domains which are selected to be measured. Early neurocognitive decline occurs within the first 1 - 4 months after WBRT for brain metastases. The domains of early neurocognitive decline principally involve verbal and short-term memory recall. Since several decades ago, it has been understood that hippocampus plays an essential role in memory function. Not little evidence supports that radiation-induced damage to hippocampus should be strongly associated with NCF impairment. Furthermore, several studies have shown that isodose distribution in hippocampus is closely related to neurocognitive function in patients with benign or low-grade brain tumors. As a consequence, it is hypothesized that conformal hippocampal sparing during the course of WBRT (HS-WBRT) might provide significant preservation in terms of cognitive function. This prospective cohort study aims to explore and evaluate the impact of the delivery of HS-WBRT on the pattern of NCF change and the extent of NCF decline in patients receiving prophylactic or therapeutic WBRT. As compared with previous related and relevant studies, it will also be investigated whether neurocognitive functional preservation can be achieved via the integration of hippocampal sparing with the course of WBRT.

The purpose of this study is to assess the safety and feasibility of Magnetic Resonance Imaging-guided focused ultrasound (MRgFUS) in patients with epilepsy whose medicines are not working well. The ExAblate transcranial system is the name of the device that will be used to create and send ultrasound waves through the scalp and skull precisely to a small structure located in the center of the brain. This structure is known as the "Anterior Nucleus", and is an important region in the brain that may cause the seizures. Safety will be measured by recording and analyzing any adverse effects that may occur from the day of the experimental surgery through 12 months following the surgery.

Patients with metastatic breast cancer with at least 2 brain metastases will receive pembrolizumab every 3 weeks. Patients will undergo stereotactic radiosurgery (SRS) to one of the brain lesions. Pembrolizumab infusion will be given on Day 4 (+/-1) after SRS treatment at the standard dose of 200mg IV over 30 minutes and repeated every 3 weeks until disease progression or unacceptable toxicity.

For newly-diagnosed patients with brain metastasis, whole brain radiation therapy (WBRT) probably remains a common palliative management even for those with oligometastatic brain disease. However, WBRT-related late sequelae, particularly a decline in neurocognitive functions (NCFs), are a major concern. More importantly, in patients with limited brain metastases and a fair/good performance status, sparing the radiosensitive and vulnerable structures which are responsible for essential NCFs during the WBRT course is one of the reasonable strategies to postpone and prevent the development of WBRT-induced neurocognitive impairments. Actually, radiation-related neurocognitive dysfunction is usually characterized as a decline involving learning and memory, in which the extremely radiosensitive hippocampus indeed plays a critical role. In addition to the neurocognitive preservation by virtue of sparing the radiosensitive structures like the hippocampus, durable intracranial tumor control critically depends on an escalated radiotherapeutic dose level which is adequate enough to eradicate gross metastatic brain lesions. Therefore, in order to achieve both hippocampal sparing and simultaneous integrated boost(s) to gross metastatic foci, a specialized WBRT technique, hippocampal avoidance during WBRT plus simultaneous integrated boost (SIB) will be adopted in this prospective study. Moreover, the dose-effect relationship would be analyzed in order to explore the correlation between the equivalent uniform dose (EUD) irradiating the hippocampus and the neurocognitive change/decline after the above WBRT course measured by objective neurocognitive test tools. Newly-diagnosed cancer patients harboring 1-3 gross metastatic lesions but still in fair/good performance statuses are potentially eligible. All recruited patients should receive baseline functional brain MRI examination and baseline neurobehavioral assessment. Treatment planning will be designed via the technique of volumetric-modulated arc therapy (VMAT) to achieve both hippocampal avoidance and simultaneous integrated boost(s) to gross metastatic lesions. Except for the above regions for which conformal avoidance or SIB is attempted, the prescribed dose to the remaining brain parenchyma will be consistently 3000 cGy in 12 fractions. Accordingly, a battery of neuropsychological measures, which includes 7 standardized neuropsychological tests (e.g., executive functions, verbal and non-verbal memory, working memory, and psychomotor speed), is used to evaluate neurobehavioral functions for our registered patients. The primary outcome measure is delayed recall, as determined by the change/decline in verbal memory or non-verbal memory, from the baseline assessment to 4 months after the start of the WBRT course. This prospective cohort study aims to examine thoroughly the impact of a specialized WBRT technique, integrating both simultaneous integrated boost(s) delivered to gross metastatic foci and conformal hippocampal avoidance, on the status of NCF change/decline in patients with oligometastatic brain disease. It is anticipated that intracranial local control will be more sustainable and durable resulting from the escalated focal dose of SIBs. Ultimately, we also expect the dose-effect relationship will be clearly demonstrated after investigating the correlation between the hippocampal dosimetry and the status of NCF change/decline after receiving HA-WBRT plus SIB.

This is a phase 1b/2 study to determine the safety and effectiveness of the combination of pembrolizumab and idelalisib in NSCLC patients whose disease has stopped responding to immune therapy. This study is being done to see if adding another immune modulator (idelalisib) to standard pembrolizumab will increase response rates, compared to the response seen with pembrolizumab alone.
