14 Clinical Trials for Various Conditions
The primary objective is to estimate the objective response rate (ORR) for metastatic Basal Cell Carcinoma (BCC) (group 1) and for unresectable locally advanced BCC (group 2) when treated with cemiplimab as a monotherapy
The purpose of this study is to demonstrate that orally administered itraconazole, a commonly used antifungal medication, can inhibit Hedgehog pathway signaling in patients with esophageal cancer, including adenocarcinoma (EAC) and squamous cell carcinoma (ESCC).
We hypothesize that administration of LDE-225 in humans with pancreatic cancer will result in inhibition of paracrine HH signaling in the pancreatic tumor stroma while having no effect on autocrine signaling in the tumor cell compartment. Furthermore we hypothesize that treatment with LDE-225 will result in changes in the tumor stroma (decreased desmoplasia, increased vascularity) that will result in improved tumor blood flow. The purpose of this study is to determine if, where and how LDE-225 works in pancreatic cancer. A cancer cell's growth can depend on the cells and tissue around it. The cells and tissue make chemical signals to influence the cancer's growth. This research study is evaluating LDE-225 designed to interfere with one of the growth signals causing pancreatic cancer growth.
This is a single-arm, multicenter, Phase Ib study designed to describe the effect of GDC-0449 on the pharmacokinetics of rosiglitazone and oral contraceptives in patients with advanced solid tumors who are refractory to treatment or for whom no standard therapy exists.
This was a Phase II, single-arm, two-cohort multicenter clinical trial evaluating the efficacy and safety of vismodegib (GDC-0449) in patients with advanced basal cell carcinoma. All patients received vismodegib until evidence of progression, intolerable toxicities most probably attributable to vismodegib, or withdrawal from the study.
The purpose of this study is to determine the safety of BMS-833923 (XL139) in patients with advanced or metastatic cancers and determine the recommended phase 2 dose range and schedule
Approximately 90% of children with malignant brain tumors that have recurred or relapsed after receiving conventional therapy will die of disease. Despite this terrible and frustrating outcome, continued treatment of this population remains fundamental to improving cure rates. Studying this relapsed population will help unearth clues to why conventional therapy fails and how cancers continue to resist modern advances. Moreover, improvements in the treatment of this relapsed population will lead to improvements in upfront therapy and reduce the chance of relapse for all. Novel therapy and, more importantly, novel approaches are sorely needed. This trial proposes a new approach that evaluates rational combination therapies of novel agents based on tumor type and molecular characteristics of these diseases. The investigators hypothesize that the use of two predictably active drugs (a doublet) will increase the chance of clinical efficacy. The purpose of this trial is to perform a limited dose escalation study of multiple doublets to evaluate the safety and tolerability of these combinations followed by a small expansion cohort to detect preliminary efficacy. In addition, a more extensive and robust molecular analysis of all the participant samples will be performed as part of the trial such that we can refine the molecular classification and better inform on potential response to therapy. In this manner the tolerability of combinations can be evaluated on a small but relevant population and the chance of detecting antitumor activity is potentially increased. Furthermore, the goal of the complementary molecular characterization will be to eventually match the therapy with better predictive biomarkers. PRIMARY OBJECTIVES: * To determine the safety and tolerability and estimate the maximum tolerated dose/recommended phase 2 dose (MTD/RP2D) of combination treatment by stratum. * To characterize the pharmacokinetics of combination treatment by stratum. SECONDARY OBJECTIVE: * To estimate the rate and duration of objective response and progression free survival (PFS) by stratum.
Historically, medulloblastoma treatment has been determined by the amount of leftover disease present after surgery, also known as clinical risk (standard vs. high risk). Recent studies have shown that medulloblastoma is made up of distinct molecular subgroups which respond differently to treatment. This suggests that clinical risk alone is not adequate to identify actual risk of recurrence. In order to address this, we will stratify medulloblastoma treatment in this phase II clinical trial based on both clinical risk (low, standard, intermediate, or high risk) and molecular subtype (WNT, SHH, or Non-WNT Non-SHH). This stratified clinical and molecular treatment approach will be used to evaluate the following: * To find out if participants with low-risk WNT tumors can be treated with a lower dose of radiation to the brain and spine, and a lower dose of the chemotherapy drug cyclophosphamide while still achieving the same survival rate as past St. Jude studies with fewer side effects. * To find out if adding targeted chemotherapy after standard chemotherapy will benefit participants with SHH positive tumors. * To find out if adding new chemotherapy agents to the standard chemotherapy will improve the outcome for intermediate and high risk Non-WNT Non-SHH tumors. * To define the cure rate for standard risk Non-WNT Non-SHH tumors treated with reduced dose cyclophosphamide and compare this to participants from the past St. Jude study. All participants on this study will have surgery to remove as much of the primary tumor as safely possible, radiation therapy, and chemotherapy. The amount of radiation therapy and type of chemotherapy received will be determined by the participant's treatment stratum. Treatment stratum assignment will be based on the tumor's molecular subgroup assignment and clinical risk. The participant will be assigned to one of three medulloblastoma subgroups determined by analysis of the tumor tissue for tumor biomarkers: * WNT (Strata W): positive for WNT biomarkers * SHH (Strata S): positive for SHH biomarkers * Non-WNT Non-SHH, Failed, or Indeterminate (Strata N): negative for WNT and SHH biomarkers or results are indeterminable Participants will then be assigned to a clinical risk group (low, standard, intermediate, or high) based on assessment of: * How much tumor is left after surgery * If the cancer has spread to other sites outside the brain \[i.e., to the spinal cord or within the fluid surrounding the spinal cord, called cerebrospinal fluid (CSF)\] * The appearance of the tumor cells under the microscope * Whether or not there are chromosomal abnormalities in the tumor, and if present, what type (also called cytogenetics analysis)
This is a multi center, open-label study to evaluate the drug-drug interaction of LDE225 on the PK of bupropion and warfarin patients with advanced solid tumors. Subjects will receive 800mg daily of LDE225 and two separate doses of either bupropion or warfarin.
Phase I dose-escalation study to characterize the safety, tolerability, pharmacokinetics and pharmacodynamics of LDE225 given orally on a daily dosing schedule in children with recurrent or refractory medulloblastoma, or other tumors potentially dependent on Hedgehog signaling pathway. Phase II study is to assess preliminary efficacy in both adult and pediatric patients with recurrent or refractory MB.
This first-in-human dose-escalation study is to characterize the safety, tolerability, pharmacokinetics and pharmacodynamics of LEQ506 given orally on a daily dosing schedule in patients with advanced solid tumors.
This was a multicenter, open-label extension study. Patients who received vismodegib (GDC-0449) in a Genentech-sponsored study and who had completed the parent study or who continued to receive vismodegib at the time the parent study closed were eligible for continued treatment in this protocol.
The purpose of this study is to determine the maximum dose of LDE225 and BKM120 that can be safely given together to patients and/or the dose that will be used in future studies. This study will also learn more about how the combination of these two investigational drugs may work for patients with certain cancers (specifically metastatic breast cancer, advanced pancreatic adenocarcinoma, metastatic colorectal cancer and recurrent glioblastoma multiforme).
Cancer results when undifferentiated cells grow in an uncontrolled manner, crowding out normal cells, causing morbidity and ultimately mortality. the cancer stem cell theory suggests that most tumors undergo a process of differentiation through which a relatively rare cancer stem or progenitor cell (CSC) gives rise to more differentiated populations of cells (including transiently amplifying cells) comprising the bulk of the tumor. As a result of this cellular diversity, one or more cells within the tumor are likely to be resistant to therapy. Among cells resistant to a given therapy, only CSCs can repopulate the tumor. A key feature of this resistant subset of CSCs is that they repopulate a tumor resistant to the original intervention. The cellular programs driving the uncontrolled proliferation of many solid tumors result from aberrant activity of Wnt, Shh, and/or Notch signaling pathways in esc. Thus, therapies that down-regulate the activity of these fundamental pathways in CSCs will be effective in the treatment of cancer. The investigator's research program focuses on the elucidation of signaling mechanisms, control of cellular processes and discovery of small molecules that selectively target Wnt, Shh, and Notch signaling pathways that are fundamental to CSCs. Our preliminary results identified a novel Notch associated protein NACK that functions as a transcriptional co-activator of Notch. Moreover, Nack is expressed in human solid tumors and is required for cell survival and tumor growth in notch -dependent tumor cells. The investigator's aim is to further interrogate the link between Notch and Nack. Specific Aims: * Identify and isolate the cancer stem cell populations from primary chemo naive esophageal tumor samples. * Interrogate the status of the Notch,( the link between Notch and Nack), Wnt and Hedghog pathways in the chemo naive esophageal tumor as well as in specific cell populations, such as the CSC. * Determine the degree of cross-talk between these pathways and which of these pathways is essential for the self renewal properties and tumorigenic properties of the esc population. * Identify critical targets for therapeutic intervention in CSC populations.
