NCT06393374
This is a randomized, open-label study comparing the efficacy and safety of adjuvant sacituzumab tirumotecan (MK-2870) in combination with pembrolizumab compared to treatment of physician's choice (TPC) in participants with triple-negative breast cancer (TNBC) who received neoadjuvant therapy and did not achieve a pathological complete response (pCR) at surgery. The primary objective is to compare sacituzumab tirumotecan plus pembrolizumab to TPC (pembrolizumab or pembrolizumab plus capecitabine) with respect to invasive disease-free survival (iDFS) per investigator assessment. It is hypothesized that sacituzumab tirumotecan plus pembrolizumab is superior to TPC with respect to iDFS per investigator assessment.
NCT07217015
This phase 2b study is designed to evaluate the safety and efficacy of KT-621 in adult and adolescent participants with moderate-to-severe atopic dermatitis (AD), a common form of eczema. The main goals of this study are to learn how effective KT-621 is at reducing the severity and extent of AD, the safety and tolerability of KT-621, how KT-621 behaves in the body, and how the body responds to KT-621. This is a 16-week double-blind, placebo-controlled study with a 52-week open-label period.
NCT06855771
The purpose of this study is to evaluate the safety and efficacy of BMS-986504 monotherapy in participants with advanced or metastatic Non-small Cell Lung Cancer (NSCLC) with homozygous MTAP deletion after progression on prior therapies.
NCT06498635
This phase III trial compares durvalumab to the usual approach (patient observation) after surgery for the treatment of patients with early-stage non-small cell lung cancer. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. The usual approach for patients who are not in a study is to closely watch a patient's condition after surgery and to have regular visits with their doctor to watch for signs of the cancer coming back. Usually, patients do not receive further treatment unless the cancer returns. This study will help determine whether this different approach with durvalumab is better, the same, or worse than the usual approach of observation. Giving durvalumab may help patients live longer and prevent early-stage non-small cell lung cancer from coming back as compared to the usual approach.
NCT05099003
This phase I/II trial tests the safety, side effects, and best dose of selinexor given in combination with standard radiation therapy in treating children and young adults with newly diagnosed diffuse intrinsic pontine glioma (DIPG) or high-grade glioma (HGG) with a genetic change called H3 K27M mutation. It also tests whether combination of selinexor and standard radiation therapy works to shrink tumors in this patient population. Glioma is a type of cancer that occurs in the brain or spine. Glioma is considered high risk (or high-grade) when it is growing and spreading quickly. The term, risk, refers to the chance of the cancer coming back after treatment. DIPG is a subtype of HGG that grows in the pons (a part of the brainstem that controls functions like breathing, swallowing, speaking, and eye movements). This trial has two parts. The only difference in treatment between the two parts is that some subjects treated in Part 1 may receive a different dose of selinexor than the subjects treated in Part 2. In Part 1 (also called the Dose-Finding Phase), investigators want to determine the dose of selinexor that can be given without causing side effects that are too severe. This dose is called the maximum tolerated dose (MTD). In Part 2 (also called the Efficacy Phase), investigators want to find out how effective the MTD of selinexor is against HGG or DIPG. Selinexor blocks a protein called CRM1, which may help keep cancer cells from growing and may kill them. It is a type of small molecule inhibitor called selective inhibitors of nuclear export (SINE). Radiation therapy uses high energy to kill tumor cells and shrink tumors. The combination of selinexor and radiation therapy may be effective in treating patients with newly-diagnosed DIPG and H3 K27M-Mutant HGG.
NCT04469439
This study will be a prospective, observational study of patients who undergo endoscopic sinus surgery for cystic fibrosis-related chronic rhinosinusitis (CRS). Individuals who do not undergo surgery but are treated medically for CRS will also be enrolled to serve as a control group. Outcomes analyzed will include pulmonary, quality of life, and others.
NCT04959097
Retinoblastoma (RB) is a primary eye cancer that forms in the back of the eye of infants and toddlers. Traditionally, RB is diagnosed without a biopsy; tumor can only be studied once an eye has been surgically removed. Given this limitation, we use aqueous humor (AH), the clear fluid in the front of the eye to detect specific markers, or information, that comes from the tumor itself.
NCT04246177
The purpose of this study is to evaluate the efficacy and safety of lenvatinib and pembrolizumab in combination with TACE versus TACE plus oral and intravenous (IV) placebos in participants with incurable, non-metastatic hepatocellular carcinoma (HCC). The primary hypotheses are that pembrolizumab plus lenvatinib in combination with TACE is superior to placebo plus TACE with respect to progression-free survival (PFS) and overall survival (OS).
NCT04396860
This phase II/III trial compares the usual treatment with radiation therapy and temozolomide to radiation therapy in combination with immunotherapy with ipilimumab and nivolumab in treating patients with newly diagnosed MGMT unmethylated glioblastoma. Radiation therapy uses high energy photons to kill tumor and shrink tumors. Chemotherapy drugs, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Temozolomide, may not work as well for the treatment of tumors that have the unmethylated MGMT. Immunotherapy with monoclonal antibodies called immune checkpoint inhibitors, such as ipilimumab and nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. It is possible that immune checkpoint inhibitors may work better at time of first diagnosis as opposed to when tumor comes back. Giving radiation therapy with ipilimumab and nivolumab may lengthen the time without brain tumor returning or growing and may extend patients' life compared to usual treatment with radiation therapy and temozolomide.
NCT07474792
This is a multicenter, randomized, double-blinded, placebo-controlled, dose-range finding study to evaluate the efficacy and safety of ORKA-002 in adult participants with moderate-to-severe plaque psoriasis.
NCT06679101
The purpose of this Phase 3 study is to evaluate if BRd prolongs progression free survival (PFS) and/or improves minimal residual disease (MRD) negative status compared with DRd in participants with TI-NDMM.
NCT06157151
This Phase 2 study will evaluate the efficacy and safety of PRGN-2009 in combination with pembrolizumab in patients with pembrolizumab-resistant recurrent or metastatic cervical cancer.
NCT05233397
ACTEMRA (tocilizumab) is an IL-6 receptor antagonist used for the treatment of adult Rheumatoid Arthritis as well as Polyarticular (PJIA) and Systemic (SJIA) Juvenile Idiopathic Arthritis. In this Phase II, the drug will be used to treat pediatric patients diagnosed with recurrent Adamantinomatous Craniopharyngioma including patients who have undergone surgery and/or radiation therapy.
NCT07544654
This study is open to adults with advanced extrapulmonary neuroendocrine cancer. The purpose of this study is to find out if a study medicine called obrixtamig plus standard chemotherapy (carboplatin and etoposide) improves survival when compared to standard chemotherapy (carboplatin and etoposide) alone. Obrixtamig is an antibody-like molecule that may help the immune system fight cancer. Another purpose of the study is to test a medical device being developed to measure levels of the tumour marker delta-like ligand 3 (DLL3). Participants are put into 2 groups randomly, which means by chance. One group (treatment arm) receives obrixtamig and standard chemotherapy followed by obrixtamig alone for up to 3 years. The other group (control arm) receives standard chemotherapy without obrixtamig for about 4 months. All treatments are given as infusions into a vein. During the study, participants in both groups visit the study site regularly. Participants in the treatment arm stay overnight at the study site following the first 2 obrixtamig treatments. The doctors regularly check participants' health and take note of any unwanted effects. At some of the visits, doctors check the size of the tumour(s). The results are compared between the 2 groups to see whether the treatment works.
NCT06631287
The overarching goal of this study is to determine if baricitinib, as compared to placebo, will improve neurocognitive function, along with measures of physical function, quality of life, post-exertional malaise, effect of breathlessness on daily activities, post-COVID-19 symptom burden, and biomarkers of inflammation and viral measures, in participants with Long COVID.
NCT06607185
The main purpose of the study is to assess whether the study drug, LY4066434, is safe and tolerable when administered to participants with locally advanced or metastatic solid tumors with certain KRAS mutations. LY4066434 will be given alone or in combination with other treatments. The study will have 2 parts: monotherapy dose escalation and dose optimization. The study is expected to last up to approximately 5 years.
NCT07440225
Researchers are looking for new ways to treat neovascular age-related macular degeneration (NVAMD). Available standard (usual) treatments for NVAMD, such as aflibercept, may not work for every person. Researchers want to learn if a trial medicine called tiespectus (also called MK-8748 or EYE201) can treat NVAMD. The goal of this trial is to learn if tiespectus works as well as aflibercept to treat NVAMD.
NCT06008756
This is a phase 3, randomized, placebo-controlled study of the efficacy and safety of enlicitide decanoate, an oral proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor, in participants with high cardiovascular risk. The primary objective is to evaluate the efficacy of enlicitide decanoate compared with placebo in increasing the time to the first occurrence of major adverse cardiovascular events (MACE) including coronary heart disease (CHD) death, ischemic stroke, myocardial infarction (MI), acute limb ischemia or major amputation, or urgent arterial revascularization.
NCT06960213
This study will evaluate the efficacy and safety of ADX-324 in participants with Type 1 or Type 2 hereditary angioedema. The study will also evaluate safety, pharmacokinetics (PK), pharmacodynamics (PD), and health-related quality of life measures.
NCT03481738
This study is an observational (ie, noninterventional), longitudinal, multicenter, global registry for patients with pyruvate kinase (PK) deficiency, a rare nonspherocytic hemolytic anemia. This Registry will be open for enrollment for 7 years and all enrolled participants will be followed prospectively for a minimum of 2 years, and up to 9 years. Data will be collected from participating Registry Physicians, participants, and, where appropriate, parents/guardians who have provided informed consent or assent (where relevant) and authorization pursuant to applicable laws and regulations. Data should include demographic, clinical, and treatment data; and other data of relevance to the management of patients with PK deficiency. Annual chart review and data entry are expected in order to enhance longitudinal understanding of PK deficiency; however, no specific protocol schedule of assessment is required by this Registry protocol.
