NCT03519178
The purpose of this clinical trial is to learn about the safety and effects of study medicine (PF-06873600) when taken alone or with hormone therapy by people with cancer. People may be able to participate in this study if they have the following types of cancer: Hormone Receptor positive (HR+) breast cancer; Human Epidermal Growth Factor Receptor 2 (HER2)-negative breast cancer that is advanced or metastatic (spread to other parts of the body); triple negative breast cancer; epithelial ovarian cancer; fallopian tube cancer; or primary peritoneal cancer. All participants in this study will receive the study medicine by mouth, 1 to 2 times a day at home. The dose of the study medicine may be changed during the study. Some participants will also receive hormone therapy. The hormone therapy will be either letrozole by mouth once a day at home, or fulvestrant as a shot into the muscle. Fulvestrant will be given every two weeks at the study clinic for the first month, and then once a month after that. Participants will take part in this study for at least 7 to 8 months, depending on how they respond to the therapy. During this time participants will visit the study clinic once a week for the first 2 cycles and every cycle thereafter.

NCT05024929
Papillary thyroid cancer (PTC) is a common type of differentiated thyroid cancer (DTC) in children and represents the second most common cancer in adolescent females. Recently targeted drugs that block many of the genetic drivers of DTC have become available. While Investigators know that these drugs shrink DTC tumors in many cases, the impact on radioactive iodine (RAI) avidity has not been systematically studied.
NCT05010564
This is a gene transfer study for patients with a type of blood cancer called Acute Lymphoblastic Leukemia (ALL) that has come back or has not gone away after treatment. The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancers. This research study combines two different ways of fighting cancer: antibodies and T cells. Antibodies are types of proteins that protect the body from infectious diseases and possibly cancer. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells, including cells infected with viruses and tumor cells. Both antibodies and T cells have been used to treat patients with cancers. They have shown promise but have not been strong enough to cure most patients. For example, T lymphocytes can kill cancer cells but there normally are not enough of them to kill all the cancer cells. Some researchers have taken T cells from a person's blood, grown more of them in the laboratory and then given them back to the person. The antibody used in this study targets CD19, CD20 and CD22. This antibody sticks to ALL cells because of a substance on the outside of these cells called CD19, CD20 and/or CD22. For this study, the antibody to CD19, CD20 and CD22 has been changed so that instead of floating free in the blood, it is now joined to the T cells. When T-cells contain an antibody that is joined to them, they are called chimeric antigen receptor- T cells or CAR-T cells. In the laboratory, we have also found that T cells work better if we also add proteins that stimulate them. One such protein is called 4-1BB. Adding the 4-1BB molecule makes the cells grow better and last longer in the body, giving them a better chance of killing the leukemia cells. In this study we are going to attach the CD19/CD20/CD22 chimeric receptor that has 4-1BB added to the patient's T cells. We will then test how long the cells last. These T cells, called "TRICAR-ALL" T cells are investigational products not approved by the Food and Drug Administration (FDA) outside the context of a clinical trial.
NCT04759911
This phase II trial studies the effect of selpercatinib given before surgery in treating patients with thyroid cancer whose tumors have RET alterations (changes in the genetic material \[deoxyribonucleic acid (DNA)\]). Selpercatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving selpercatinib before surgery may help shrink the tumors and help control the disease.
NCT06454916
The primary objective of this trial is to investigate the safety and effectiveness of the Flexagon SFM system plus OTOLoc when used to create a small bowel anastomosis in subjects undergoing laparoscopic small bowel surgery.
NCT05111613
A prospective, multicenter, randomized controlled trial of the FlowTriever System compared to Catheter-Directed Thrombolysis (CDT) for use in the treatment of acute pulmonary embolism. The trial includes a non-randomized cohort of subjects with an absolute contraindication to thrombolysis.
NCT02101788
This phase II/III trial studies how well trametinib works and compares it to standard treatment with either letrozole, tamoxifen, paclitaxel, pegylated liposomal doxorubicin, or topotecan in treating patients with low-grade ovarian cancer or peritoneal cavity cancer that has come back (recurrent), become worse (progressive), or spread to other parts of the body. Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether trametinib is more effective than standard therapy in treating patients with ovarian or peritoneal cavity cancer.
NCT04417257
A randomized, double-blind, placebo-controlled Phase 2/3 Study of LAU-7b against confirmed COVID-19 Disease in hospitalized patients at a higher risk of complications.
NCT01878617
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)
