Active clinical trials for "Neoplasms"

This is a multicenter, open-label phase II study in subjects with relapsed and/or refractory multiple myeloma with at least two prior lines of therapy. The main study consists of three phases: a 28-day screening phase, treatment phase that consists of 28-day cycles of isatuximab with elotuzumab, pomalidomide, and dexamethasone and a follow-up phase.

This study evaluates KRT-232, a novel oral small molecule inhibitor of MDM2, for the treatment of patients with Ph+ Chronic Myeloid Leukemia (CML) who have relapsed or are refractory or intolerant to a Tyrosine Kinase Inhibitor (TKI). This study is a global, open label Phase 1b/2 to determine the efficacy and safety of KRT-232 in patients with chronic phase CML (CML-CP) and accelerated phase (CML-AP) who have failed TKI treatments.

This Phase II randomized study is to determine the efficacy and toxicity of toripalimab plus neoadjuvant chemotherapy combined with chemoradiotherapy for locally advanced unresectable esophageal squamous cell carcinoma.

The purpose of this study is to characterize the safety, tolerability, pharmacokinetics, pharmacodynamics, and antitumor activity of CFT7455 administered orally in subjects with Relapsed/Refractory (r/r) Non-Hodgkin's Lymphoma (NHL) or Multiple Myeloma (MM) administered according to different dosing schedules as a single agent and in combination with dexamethasone.

Anlotinib hydrochloride is a multi-target antiangiogenic drug. It was recommended by Chinese Society of Clinical Oncology(CSCO) guideline as a third-line treatment for advanced small-cell lung cancer. This study intends to assess the efficacy and safety of anlotinib hydrochloride combined with irinotecan or docetaxel for second line treatment of nonsensitive relapsed small-cell lung cancer.

Background There is currently no reliable means to restage rectal cancers after neoadjuvant chemoradiation. There are still no reliable methods to identify patients with pCR before radical surgery. As a result, clinical complete response (cCR), defined as no clinical detectable tumor by physical examination, endoscopic evaluation, and imaging, is designed as a surrogate endpoint for pCR. However, the concordance between cCR and pCR varies from 22% to 96% in different reports, which questions the clinical value of such strategies. Therefore, based on rectal diginal examination, serum CEA, MRI, endoscopy examination, we suggested to add multi-points and full-thickness biopsy technique to further improve the accuracy of cCR.

This research study will add an anti-cancer drug (called inotuzumab ozogamicin also known as "InO") to treatment for participants with newly diagnosed Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL). Doctors leading this study hope to learn if adding InO to standard induction treatment for Ph+ ALL will lead to quicker, complete molecular remission (where the disease is not detectable even with very sensitive testing techniques). The purpose of this research is to gather information regarding the effectiveness of InO in newly-diagnosed Ph+ ALL patients that have not yet received treatment.

Optical coherence tomography guided laser treatment of basal cell carcinoma

Low-grade gliomas (LGGs) are the most common brain tumors in children, and a subset of these tumors are treated definitively with focal radiation therapy (RT). These patients often survive for many years after receiving RT and experience late deficits in memory. Verbal recall is an important measure of memory and is associated with other important functional outcomes, such as problem-solving, independence of every-day functioning, and quality of life. Decline in memory, as measured by verbal recall, is associated with RT dose to the hippocampi. Therefore, this phase II study investigates the feasibility of reducing RT doses to the hippocampi (i.e., hippocampal avoidance [HA]) by using proton therapy for midline or suprasellar LGGs. Primary Objective: To determine the feasibility of HA with proton therapy in suprasellar or midline LGGs. Feasibility will be established if 70% of plans meet the first or second dose constraints shown below. First priority RT dose constraints for bilateral hippocampi: volume receiving 40 CGE (V40CGE) ≤ 25%, dose to 100% of Hippocampus (D100%) ≤ 5CGE. Second priority RT dose constraints for bilateral hippocampi: V40CGE ≤ 35%, D100% ≤ 10 CGE. Secondary Objectives: To estimate the 3-year event-free-survival (EFS) for LGGs treated with HA. To estimate the change in California Verbal Learning Test short-term delay (CVLT-SD) from baseline to 3 years and from baseline to 5 years To compare CVLT-SD and Cogstate neurocognitive scores in patients with proton therapy plans that: (1) meet first priority RT dose constraints, (2) meet second priority RT dose constraints but not first priority RT dose constraints, and (3) that did not meet either first or second RT priority dose constraints Exploratory Objectives: To describe the change in overall cognitive performance from baseline to 3 years and from baseline to 5 years with an age appropriate battery, including gold standard measures shown in the published studies to be sensitive to attention, memory processing speed and executive function that will afford comparison to historical controls. To characterize longitudinal changes in connection strength within brain networks in the first 3 years after proton therapy and to investigate associations between these changes and neurocognitive performance with focus on the hippocampi. To correlate the distribution and change in L-methyl-11C-methionine positron emission tomography (MET-PET) uptake to tumor progression and from baseline to 3 years and to investigate whether cases of pseudoprogression exhibit a differential pattern of uptake and distribution compared to cases of true progression after controlling for histology. To investigate the effect of BRAF alteration, tumor histology and tumor location on PFS and OS in a prospective cohort of patients treated in a homogenous manner. To investigate whether the methylation profiles of LGGs differ by tumor location (thalamic/midbrain vs. hypothalamic/optic pathway vs. others) and histologies (pilocytic astrocytoma vs. diffuse astrocytoma vs. others), which, in conjunction with specific genetic alterations, may stratify patients into different subgroups and highlight different therapeutic targets. To record longitudinal measures of circulating tumor DNA (ctDNA) in plasma and correlate these measures with radiographic evidence of disease progression. To bank formalin-fixed, paraffin-embedded (FFPE)/frozen tumors and whole blood from subjects for subsequent biology studies not currently defined in this protocol. To quantify and characterize tumor infiltrating lymphocytes (TILs) and to characterize the epigenetics of T cells and the T cell receptor repertoire within the tumor microenvironment. To estimate the cumulative incidence of endocrine deficiencies, vision loss, hearing loss and vasculopathy after proton therapy and compare these data to those after photon therapy.

Laser surgery and radiotherapy are well-established standards of care for unilateral stage 0 & I carcinoma in situ (Cais) and squamous cell carcinoma of glottic larynx (SCCGL). Based on meta-analyses, functional and oncological outcome after both treatment modalities are comparable1-5. However, no properly conducted randomized trials comparing these treatments exist. The only such trial with the endpoint of voice quality had to be prematurely closed due to low accrual6. The traditional radiotherapy involves the treatment of the whole larynx. Recently, a new radiotherapy technique was introduced by a team of researchers from Netherlands, where the treated target volume consists of involved vocal cord and therefore 8 to 10-fold smaller than the target volumes used for traditional whole larynx irradiation. The treatment is reduced to 16 fractions which corresponds to 3 weeks and a day7-12. The results of a prospective cohort (n=30) with single vocal cord irradiation (SVCI) were compared with the results of a historical prospective cohort previously treated with whole larynx radiotherapy (n=131) in the same institute. The median follow-up was 30 months. The voice handicap index (VHI) at all time points beginning from the 6th week after SVCI was significantly superior to the same time points with conventional radiotherapy. Moreover, a comparable local control with SVCI (100%) vs. conventional radiotherapy (92%) was reported at two years, p=0.2412. Based on this information, the investigators' main aim is to compare SVCI to Transoral CO2-Laser Microsurgical Cordectomy (TLM) with the main focus of patient-reported voice quality.
