NCT03502668
Multicenter, open-label study of various ASTX727 LD doses and schedules to assess safety, pharmacodynamics, pharmacokinetics, and hematologic response in subjects with International Prognostic Scoring System (IPSS) risk category of low-risk or Intermediate-1 MDS. This study will be conducted in two phases. In phase 1 subjects will be randomized into 3 cohorts in a 28-day cycles. Phase 2, 80 new subjects will be randomized in a 1:1 ratio into 2 doses/schedules.
NCT03833167
This is a randomized, double-blind, study that compares pembrolizumab (MK-3475) with placebo given as adjuvant therapy in participants with high-risk locally advanced cutaneous squamous cell carcinoma (LA cSCC) that have undergone surgery with curative intent in combination with radiotherapy. The primary hypothesis is that pembrolizumab is superior to placebo in increasing recurrence free survival (RFS).
NCT07459621
The goal of this study is to compare the effectiveness of two smoking cessation programs to determine which better helps people change their smoking behavior, the control or the experimental intervention? Both interventions include access to a mHealth app and other publicly available stop-smoking resources. The two app versions each include best practice advice and guidance for quitting smoking, but one includes additional content designed for people who aren't ready to quit smoking. We hypothesize that people who receive the experimental intervention will be more likely to request additional stop-smoking resources offered through the intervention and report smoking abstinence after 6 months. We also hypothesize people assigned to the experimental app will have better app engagement and be more likely to report positive changes in their smoking behavior and use of other evidence-based stop smoking treatments that are publicly available.
NCT03660826
This phase II trial studies the effects of the combination of olaparib and durvalumab, cediranib and durvalumab, olaparib and capivasertib, and cediranib alone in treating patients with endometrial cancer that has come back (recurrent) or does not respond to treatment (refractory). Olaparib, cediranib, and capivasertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Durvalumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Testing the combinations may lower the chance of endometrial cancer growing or spreading compared to usual care.
NCT07177352
This study is a pre-screening process used to assess participants' potential eligibility for Roche interventional Alzheimer's disease studies.
NCT03178552
This is a phase 2/3, global, multicenter, open-label, multi-cohort study designed to evaluate the safety and efficacy of targeted therapies or immunotherapy as single agents or in combination in participants with unresectable, advanced or metastatic NSCLC determined to harbor oncogenic somatic mutations or positive by tumor mutational burden (TMB) assay as identified by a blood-based next-generation sequencing (NGS) circulating tumor DNA (ctDNA) assay.
NCT07218029
Researchers are looking for more ways to treat PAH. In PAH, the blood vessels in the lungs become thick and narrow, which makes it harder for blood to flow. This causes high blood pressure in the lungs and overworks the heart. PAH can make it hard to breathe and be active. Some standard (usual) treatments for PAH can treat symptoms of PAH but do not stop PAH from getting worse. Sotatercept is a study medicine designed to treat PAH. It is a targeted therapy, which is a treatment that works on certain proteins that play a role in causing PAH. This is a long-term follow-up (LTFU) study. People who took part in certain other studies testing sotatercept for PAH may be able to join this study. The goal of this study is to learn about the long-term safety of sotatercept and if people tolerate it when taken with standard PAH treatment over a longer period of time.
NCT05945329
Prospective, randomized, controlled study to assess the safety and effectiveness of GalaFLEX LITE™ Scaffold in revision surgery for reduction of capsular contracture recurrence and/or malposition in implant-based breast augmentation patients versus patients undergoing conventional revision surgery with no supportive matrix or acellular dermal matrix (ADM). Subjects will be randomized 2:1 to receive either GalaFLEX LITE™ Scaffold or standard care (no ADM or matrix placement). This study is designed using an adaptive approach. The number of the treated breasts will range between 250 and 530.
NCT06472245
Multicenter, randomized (2:1), open-label phase 3 study in HLA-A2 positive patients with squamous and non-squamous metastatic NSCLC with ICI secondary resistance. Patients will be randomized into 2 arms (randomization 2:1): experimental Arm A with OSE2101 monotherapy or control Arm B SoC with docetaxel monotherapy. Stratification factors will be histology (squamous versus non squamous) and ECOG Performance Status (0 versus 1).
NCT06649110
A study to learn about the treatment LTP001 in healthy participants (Part A) and in participants with PAH (Part B)
NCT06694805
This study will assess how effective, safe, and long-lasting a long-acting antiretroviral therapy (ART) using CAB LA + RPV LA is for people with HIV who still have detectable virus levels despite being on oral ART. The study will also consider feedback from patients on their experience with this treatment.
NCT04221542
The overall aim of the trial is to evaluate the safety, tolerability, and pharmacokinetics (PK) of AMG 509 (monotherapy and in combination with abiraterone acetate and enzalutamide) and to evaluate preliminary efficacy. As of Protocol Amendment 10 (09 July 2025), only Parts 4A expansion, 6, and 7 are open to accrual.
NCT06534892
The purpose of this study is: * To investigate the optimal timing for revaccination after the initial RSVPreF3 OA vaccine dose, * To evaluate the long-term immune persistence and safety up to 5 consecutive RSV seasons (approximately 60 months) of a single dose of RSVPreF3 OA vaccine, * To give the opportunity to participants who received only placebo in the RSVOA=ADJ- 006 study, to receive a dose of the RSVPreF3 OA vaccine and collect additional safety information.
NCT05769777
This is a single group, 1-arm, long-term safety study for treatment of participants with moderate to severe atopic dermatitis (AD). The purpose of this study is to characterize the long-term safety and efficacy of amlitelimab in treated participants with age ≥12 years old with moderate to severe AD. The study duration per participant will be up to 284 weeks, including: * A screening period of up to 2 to 4 weeks * An open label treatment period of up to 268 weeks (approximately 5 years) * A post-treatment safety follow-up period of at least 20 weeks after the last dose administration (last IMP administration at Week 264) The planned number of visits will be 35 visits.
