NCT06560021
The proposed study is a multicenter parallel group clinical trial that will include 821 evaluable patients per group who will be randomly assigned to either high definition white light colonoscopy (HDWLC) with targeted biopsies plus 2 random biopsies in 4 segments to assess for inflammation (limited biopsy strategy) or HDWLC with targeted biopsies plus 4 biopsies every 10 cm throughout the colon, at a minimum in all segments of the colon known to have been affected by IBD at any time, regardless of the extent of disease (random biopsy strategy). Participants will be followed until total proctocolectomy or the end of the study period to determine whether the two methods of surveillance colonoscopy are associated with detection of dysplasia or sessile serrated adenoma at follow-up colonoscopy. Follow-up via chart review may continue for up to 15 years from enrollment.
NCT06880744
Ulcerative colitis (UC) is a type of inflammatory bowel disease that causes inflammation and bleeding from the lining of the rectum and colon (large intestine).This study will evaluate how safe and effective risankizumab is compared to vedolizumab in treating adult participants with moderate to severe UC who are naive to targeted therapies (TaTs). Risankizumab and vedolizumab are approved medications for moderate to severe UC in multiple countries. Participants who meet the eligibility criteria will be randomized in a 1:1 ratio to receive open label risankizumab or vedolizumab. Approximately 530 adult participants with moderate to severe UC who are naïve to targeted therapies (TaTs) will be enrolled at 285 sites worldwide. For participants randomized to risankizumab, drug will be administered intravenous(IV) during the induction period followed by subcutaneous injection during the maintenance period. Participants randomized to vedolizumab will receive drug IV throughout the study. The duration of the study is approximately 69 weeks for participants randomized to risankizumab and 71 weeks for participants randomized to vedolizumab. This includes up to a 35-day screening period followed by a treatment period of 44 weeks for risankizumab and 46 weeks for vedolizumab. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular outpatient visits during the study. The effect and safety of the treatment will be checked by medical assessments, evaluation of side effects and completing questionnaires.
NCT07217171
The goal of this study is to evaluate the safety and effectiveness of EVOLVE104 in participants with advanced urothelial and squamous cell carcinomas who have previously taken standard treatment options, have declined or have been ineligible for treatment with these medications. Participants with advanced or metastatic cancer who meet all eligibility criteria may be eligible to participate in the study.
NCT04803201
This phase II trial studies the effect of duvelisib or CC-486 and usual chemotherapy consisting of cyclophosphamide, doxorubicin, vincristine, etoposide, and prednisone in treating patients with peripheral T-cell lymphoma. Duvelisib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as CC-486, cyclophosphamide, doxorubicin, vincristine, etoposide and prednisone, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. This trial may help find out if this approach is better or worse than the usual approach for treating peripheral T-cell lymphoma.
NCT03258554
This phase II/III trial studies how well radiation therapy works with durvalumab or cetuximab in treating patients with head and neck cancer that has spread to a local and/or regional area of the body who cannot take cisplatin. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. 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. Cetuximab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. It is not known if radiation therapy with durvalumab will work better than the usual therapy of radiation therapy with cetuximab in treating patients with head and neck cancer.
NCT06744920
A study to evaluate the efficacy, safety and tolerability of Remibrutinib versus placebo in adult patients with Generalized Myasthenia Gravis who are on stable, standard-of-care (SOC) treatment.
NCT04983030
A multicenter, randomized, parallel-group, placebo-controlled, double-blind, Phase 1/2a clinical study to investigate the safety, tolerability, immunogenicity and exploratory efficacy of a vaccine regimen consisting of an Ad26.Mos4.HIV prime and a boost with Modified Vaccinia Ankara (MVA)-BN-HIV in combination with broadly neutralizing antibodies (bNAb) PGT121, PGDM1400, and VRC07-523LS in human immunodeficiency virus type 1 (HIV-1)-infected study participants on suppressive anti-retroviral therapy (ART).
NCT06161584
A Prospective, Multicenter, Open-Label, Observational Phase 4 Study to Evaluate Real-World Safety, Tolerability, and Treatment Patterns of Pegcetacoplan (Syfovre) in Patients with Geographic Atrophy Secondary to Age-Related Macular Degeneration
NCT06864988

NCT01016834
The purpose of the study is to evaluate the treatment satisfaction of subjects using Sumavel DosePro to treat their moderate to severe migraines.
NCT05162976
This phase I trial tests the safety and best dose of CC-486 (an oral form of azacitidine) when given together with nivolumab in treating patients with Hodgkin lymphoma that does not respond (refractory) to PD1-based immunotherapy or has come back (relapsed). CC-486 is in a class of medications called demethylation agents. It works by helping the bone marrow to produce normal blood cells and by killing abnormal cells. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving CC-486 in combination with nivolumab may render nivolumab more effective.
NCT06616194
The purpose of this study is to learn about the effect of a study medicine called rimegepant in adolescents who have frequent migraine attacks. Rimegepant is a tablet that dissolves when you put it on or under your tongue. The study will enroll participants who have headache for 15 days (or more) every month, of which 8 days (or more) of migraine every month, and each untreated attack lasts for an average of 4-72 hours In the 1st part of the study approximately half of the participants will receive a rimegepant tablet every other day, and approximately half of the participants will receive an inactive oral tablet (that looks the same as the rimegepant tablet) every other day. Participant experiences when they are taking the study medicine will be compared to when they are taking the inactive tablet. This will help to determine if the study medicine is safe and effective. The 1st phase of the study will last 3 months. In the 2nd part of the study all the participants who stay on study will receive rimegepant tablet every other day. This 2nd phase of the study will last 1 year. This will help determine if the study medicine is safe when taken for a long period. Those who will participate in both phases will have up to 19 visits at the study clinic, about one every 4 weeks (this may vary from 2 to 8 weeks interval during the study). Home health visits may occur as well. A health check and blood sample will be conducted at all visits. Participants will have to complete a daily diary to record the migraine attacks.
NCT05997641
The goal of this clinical trial is to evaluate the safety, tolerability, and pharmacokinetics (PK; drug metabolism) of DF-003 after oral administration of single and multiple ascending doses in healthy subjects. The choice of using healthy subjects is standard in establishing the preliminary safety and PK profile of a drug. DF-003 is a potent small molecule inhibitor of alpha-kinase 1 (ALPK1), which plays an important role in immunity and inflammation. DF-003 can inhibit the immune inflammatory response and has been shown to reduce renal fibrosis in preclinical models. Thus, this study aims to determine the role of DF-003 in the treatment of chronic kidney disease. This study will include 2 parts. Part 1 is a single ascending dose (SAD) phase with an optional food effect (FE) assessment, while Part 2 is a multiple ascending dose (MAD) phase. Part 1 - SAD Phase with optional FE assessment will include approximately 64 subjects (up to 8 cohorts of 8 subjects each) and Part 2 - MAD Phase will include approximately 32 subjects (up to 4 cohorts of 8 subjects each). Therefore, up to 96 subjects will be included in the study. Study participants will be screened approximately 42 days within the first scheduled administration of study medication. Screening data will be reviewed to determine subject eligibility. In Part 1, subjects will be randomly assigned to receive a single oral dose of DF-003 (3 x 1 milligram capsules) or matching placebo. The doses to be evaluated in Part 2 will be determined based on review of the available safety and PK data from Part 1. Subjects will be monitored for adverse events (AEs) and data will be collected for physical examination, eye examination, vital signs, 12-lead electrocardiogram (ECG), Holter monitoring, and clinical laboratory findings at various timepoints throughout the study.

This is a Phase 1/2, open-label, multi-center, multi-cohort, non-randomized dose escalation and dose expansion basket study to determine the safety and tolerability of NKX019 (allogeneic CAR NK cells targeting CD19) in participants with autoimmune diseases.
NCT06636383
The main objective of this observational study is to evaluate the long-term safety and effectiveness of DTX401 for at least 10 years after DTX401 administration.
NCT07549503
This is a prospective multi-center, longitudinal study to determine efficacy of 50 percent Immunosuppression (IS) reduction. One hundred fully eligible participants will reduce IS by 50 percent in two steps. Liver tests will be checked every 0.5 months through month 4, once a month through month 12, and every other month through month 18. Liver transplant (LTx) center visits will take place at screening, months 6, 12 and 18 after initiating IS dose reduction. A protocol driven liver biopsy to adjudicate the endpoint will be performed at 18 months. The duration of the study from time of starting IS dose reduction to the primary endpoint assessment is 18 months. The primary objective is to assess the efficacy of 50 percent IS dose reduction in children with Liver transplants (LTxs)
