The aim of this study is to assess the efficacy and safety of GSK4527226 in participants with early Alzheimer's Disease (AD) (including mild cognitive impairment \[MCI\] and mild dementia due to AD) of 2 dose levels of GSK4527226 compared to placebo.
NCT04677777
The HEMERA-1 Extension (Part III) is a prospective, open-label, multicenter study to evaluate safety of two doses of PP-007 in Acute Ischemic Stroke (AIS) subjects receiving Intravenous Thrombolysis (IVT) or mechanical thrombectomy (MT) or IVT+MT as standard of care (SOC). Subjects will receive two doses of PP-007 infusion 24 ± 6 hours apart in addition to the site-specific SOC protocol. PP-007 is PEGylated bovine carboxyhemoglobin and will be administered via IV infusion. The effects on collateral flow, infarct size and functional outcomes will be evaluated.
NCT05904704
This clinical trial evaluates the feasibility of performing oxygen-enhanced magnetic resonance imaging (MRI) to generate hypoxia maps in patients with intracranial tumors. Decreased levels of oxygen (hypoxia) is a hallmark of malignant brain tumors. Chronic hypoxia is a stimulator of blood vessel formation, which is required for tumor growth and spread. Hypoxia also limits the effectiveness of radiation and chemotherapy. MRI is an imaging technique that uses radiofrequency waves and a strong magnetic field rather than x-rays to provide detailed pictures of internal organs and tissues. The administration of inhaled oxygen allows for an increased MRI signal effect size. Oxygen-enhanced MRI may be a non-invasive method that can physiologically estimate tissue hypoxia. With a better understanding of the extent of tumor hypoxia, more effective and patient-specific therapies could be devised to halt malignant tumor growth.
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.
NCT03363893
This is a modular, Phase I/II, multicentre study to investigate CT7001 monotherapy in advanced solid malignancies and to further investigate CT7001 as monotherapy or in combination with standard therapy in specific participant groups with Triple Negative Breast Cancer (TNBC), Castrate Resistant Prostate Cancer (CRPC) and in combination with fulvestrant for patients with hormone receptor-positive (HR+ve) / human epidermal growth factor-2 negative (HER2-ve) breast cancer.

Eligible participants will be randomized 1:1 into 1 of 2 study arms: Arm SC: Isatuximab SC + Pd Arm IV: Isatuximab IV + Pd Participants will be allowed to continue therapy until disease progression, unacceptable adverse events (AEs), participant request to discontinue therapy or any other reason, whichever comes first.
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.
NCT04880434

NCT04064060
A Phase 3b, open-label, single-arm, rollover study to evaluate the long-term safety of luspatercept, to the following participants: * Participants receiving luspatercept on a parent protocol at the time of their transition to the rollover study, who tolerate the protocol-prescribed regimen in the parent trial and, in the opinion of the investigator, may derive clinical benefit from continuing treatment with luspatercept * Participants in the follow-up phase previously treated with luspatercept or placebo in the parent protocol will continue into long-term post-treatment follow-up in the rollover study until the follow-up commitments are met * The study design is divided into the Transition Phase, Treatment Phase and Follow-up Phase. Participants will enter transition phase and depending on their background will enter either the treatment phase or the Long-term Post-treatment Follow-up (LTPTFU) phase * Transition Phase is defined as one Enrollment visit * Treatment Phase: For participants in luspatercept treatment the dose and schedule of luspatercept in this study will be the same as the last dose and schedule in the parent luspatercept study. This does not apply to participants that are in long-term follow-up from the parent protocol * Follow-up Phase includes: \- 42 Day Safety Follow-up Visit * During the Safety Follow up, the participants will be followed for 42 days after the last dose of luspatercept, for the assessment of safety-related parameters and adverse event (AE) reporting \- Long-term Post-treatment Follow-up (LTPTFU) Phase * Participants will be followed for overall survival every 6 months for at least 5 years from first dose of luspatercept in the parent protocol, or 3 years of post-treatment from last dose, whichever occurs later, or until death, withdrawal of consent, study termination, or until a subject is lost to follow-up. Participants will also be monitored for progression to AML or any malignancies/pre-malignancies. New anticancer or disease related therapies should be collected at the same time schedule Participants transitioning from a parent luspatercept study in post-treatment follow-up (safety or LTPTFU) will continue from the same equivalent point in this rollover study. The ACE-536-LTFU-001 rollover study will be terminated, and relevant participants will discontinue from the study when all participants fulfill 5 years on the study, including treatment and follow-up.

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)
NCT05855109
