Open-label, multicenter, dose titration and four-arm expansion trial to evaluate the safety, tolerability, immunogenicity, and preliminary efficacy of BNT112 cancer vaccine (BNT112) monotherapy or in combination with cemiplimab in patients with metastatic castration resistant prostate cancer (mCRPC: Part 1 and Part 2 Arms 1A and 1B) and in patients with high-risk, localized prostate cancer (LPC). As of February 2023, the trial only recruited LPC patients and no longer mCRPC patients.
The purpose of this study is to identify 15 patients with autonomic failure and obtain blood samples for RNA from those participants and 15 control subjects within the same age range. The stabilized blood samples, along with a limited data set, will be shipped to Western Michigan University where the actual laboratory analysis (a separate study) of the samples will take place. Unique genetic inscriptions, called gene expression signatures, are currently being identified for many diseases, including neurological diseases. The secondary goal of this study is to support the research being done at WMU and they try to look for MSA-specific signs are present in whole blood samples of MSA patients at late-stages of the disease. This is a pilot study that has a long term goal (through additional studies) a MSA-specific gene expression signature for the development of a diagnostic test for this disease that can be used in the future. Other patient groups with autonomic failure, characterized by significant drop in blood pressure on standing, will also be included in this study, to look for similar genetic inscriptions. This pilot study is expected to last for 2 years. The investigators at WMU will need some de-identified health Information about the subjects, including their age at diagnosis, age (when sample drawn) and list of their medications
This is a phase 1, first-in-human (FIH) trial for two vaccines, DV700P-RNA and DV701B1.1-RNA. This means it is the first time these study products are being tested in people. The purpose of this study is to see if the study products are safe, if people are able to take them without becoming too uncomfortable, and how a person's immune system responds to them (a person's immune system protects them from infections and disease). Forty-five volunteers without HIV and in overall good health, aged 18 to 55 years, will be enrolled and be in this study for about 16 months (about 12 visits), Study procedures will include blood draws, injections, and the collection of white blood cells and cells from their lymph nodes.
Endometriosis is a common disease that affects up to 10% of women of reproductive age. Diagnosis, however, is typically delayed (up to 12 years) and is usually made after surgery. A key unmet need therefore is an accurate biomarker that can be used to detect the disease early. This study is a prospective trial to identify candidate mRNA-markers which can be used to aid in the diagnosis of this disease. It is a discovery/validation study that will identify and confirm a gene expression panel that is specific for endometriosis and provides a non-invasive tool for future use.
Infections are a major cause of morbidity and mortality in patients undergoing hematopoietic stem cell transplant (HSCT). The purpose of this study is to evaluate if metagenomic next-generation sequencing (mNGS) can detect microbial signatures in people undergoing HSCT, and if microbial identification can be correlated with clinical features of infection (e.g., fever). Participants undergoing HSCT as part of other studies at the NIH Clinical Center (CC) will provide blood before the transplant and through 6 months after. Total nucleic acid will be extracted from plasma and subjected to mNGS. The primary objective of this study is to investigate if by using plasma and an mNGS approach, we can detect bacterial, fungal, protozoan, or viral DNA/RNA over time, in immunocompromised patients undergoing transplantation. Secondary objectives are to: (1) To correlate microbial identification with episodes of fever or clinical suspicion of infection; and to (2) correlate change in microbial signatures in patients with suspected immune reconstitution inflammatory syndrome. The study is conducted at the NIH Clinical Center. Participants, aged 3 years and older, on other research studies at the NIH CC who are undergoing HSCT are invited to take part of this study. Expected participation is up to six months.
The purpose of this study is to test the accuracy of using RNA in blood as a way to forecast new fracture healing outcome.
The purpose of this research is to learn if the CellSearch Circulating Tumor Cells (CTC) test can help doctors in making decisions about treatment and monitoring of breast cancer. The test consists of diagnostic CTC counts (enumeration) and expression of biomarkers Human Epidermal growth factor Receptor 2 (HER2), Estrogen Receptor (ER), and programmed death-ligand 1 (PD-L1) and cell free DNA/RNA (cfDNA/RNA) analysis.
The goal of this clinical trial is to assess the safety, tolerability and immunogenicity of three dosage levels, and a single or two-dose administration regimen, of the investigational HDT-321 product administered intra-muscularly. The main questions it aims to answer are: * Is HDT-321 safe to use * Does HDT-321 provide protection against Crimean-Congo hemorrhagic fever virus (CCHFV) Researchers will record any adverse events and test blood samples to see if HDT-321 is safe and works to protect participants against Crimean-Congo hemorrhagic fever virus (CCHFV) Participants will: * Receive 1 or 2 doses of HDT-321 * Complete a memory aid and measurements for 7 days after receiving each dose of HDT-321 * Be followed throughout the study using phone calls and clinic visits to check for and record adverse events * Provide blood samples at specific study visits
This is a first-in-human clinical study to evaluate the safety, tolerability and efficacy of RXRG001 administered in the ducts of the parotid glands in adult patients with radiation-induced xerostomia (dry mouth) and hyposalivation (reduced saliva production). In Part 1 of the study (open-label, single-arm), patients will receive unilateral administrations of RXRG001 in 3 single ascending dose cohorts and in 3 multiple ascending dose cohorts. Part 2 of the study has a randomized, double-blind, placebo-controlled design. Patients will receive bilateral administrations of RXRG001 in 3 multiple ascending dose cohorts.
The purpose of the SENTRY (Stability Enhanced Transcriptional Analytics) Study is to test whether combining a unique analytical approach with changes in platelet RNA expression accurately diagnoses ovarian cancer. Using retrospective data, the investigators have developed an approach that appears to accurately classify ovarian cancer with relatively high sensitivity and specificity. The SENTRY Study will build upon these retrospective analyses to prospectively recruit women with ovarian cancer or an ovarian mass (and healthy control women), obtain platelet RNA samples from whole blood, and perform validation analyses to test our hypothesis.
The purpose of this study is to learn if modified RNA (modRNA) vaccines for the prevention of influenza are: * safe; and * how these vaccines produce an immune response in generally healthy adults. Immune response is the way the body protects itself against things it sees as harmful or foreign. RNA (also called ribonucleic acid) is one of two types of nucleic acid made by cells. RNA contains information that has been copied from DNA (the other type of nucleic acid). Cells make several different forms of RNA, and each form has a specific job in the cell. Many forms of RNA have functions related to making proteins. RNA is also the genetic material of some viruses instead of DNA. RNA can be made in the laboratory and used in research studies. Also called ribonucleic acid. Influenza is term used for flu illness. It is an infection caused by a virus that affects your mouth, nose, and throat. The study is seeking for participants who: * are at least 18 years of age * have not received an influenza vaccine within the last 6 months * are generally healthy This study will be divided into three sub-studies: Substudy A (SSA), Substudy B (SSB), and Substudy C (SSC). All participants, regardless of sub-study, will receive 1 dose of either of the following vaccines as an injection into their arm: * 1 of the modRNA influenza vaccines that is being studied; or * an approved influenza vaccine approved for use in their respective age group. Participants will be involved in this study for about 6 months. During this time, participants will have at least 3 clinic visits.
Newborns with congenital heart disease (CHD) are at increased risk of developing postpartum and postoperative blood clots after cardiac surgery. The molecular mechanisms that are responsible for the clotting profile predisposing children to blood clots in the early stages of life are currently not well described. The goal of this proposal is to prospectively collect plasma samples from ten (10) neonates with antenatal diagnosis of severe congenital heart disease (CHD) to better understand mechanisms responsible for abnormal clotting in the perioperative period.
This is a Phase I study to demonstrate the manufacturing feasibility and safety, and to determine the maximum tolerated dose (MTD) of RNA-LP vaccines in adult patients with recurrent glioblastoma.
The Primary objective of this study is to determine, using unblinded samples, if it is possible to develop an algorithm for the classification of specific blood RNA from patients with long COVID together and separately from the apparent health normal controls and other medical conditions that share the signs and symptoms of long COVID.
This phase II ADC MATCH screening and multi-sub-study treatment trial is evaluating whether biomarker-directed treatment with one of three antibody-drug conjugates (ADCs) (sacituzumab govitecan, enfortumab vedotin, and trastuzumab deruxtecan) works in treating patients with solid tumor cancers that have high expression of the Trop-2, nectin-4, or HER2 proteins and that may have spread from where they first started (primary site) to nearby tissue, lymph nodes, or distant parts of the body (advanced) or to other places in the body (metastatic). Precision medicine is a form of medicine that uses information about a person's genes, proteins, and environment to prevent, diagnose, or treat disease in a way that is tailored to the patient. ADCs such as sacituzumab govitecan, enfortumab vedotin, and trastuzumab deruxtecan are monoclonal antibodies attached to biologically active drugs and are a form of targeted therapy. Sacituzumab govitecan is a monoclonal antibody, called sacituzumab, linked to a drug called govitecan. Sacituzumab attaches to a protein called Trop-2 on the surface of tumor cells and delivers govitecan to kill them. Enfortumab vedotin is a monoclonal antibody, enfortumab, linked to an anticancer drug called vedotin. It works by helping the immune system to slow or stop the growth of tumor cells. Enfortumab attaches to a protein called nectin-4 on tumor cells in a targeted way and delivers vedotin to kill them. Trastuzumab deruxtecan is composed of a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug, called deruxtecan. Trastuzumab attaches to HER2 positive tumor cells in a targeted way and delivers deruxtecan to kill them. Personalized treatment with sacituzumab govitecan, enfortumab vedotin, or trastuzumab deruxtecan may be an effective treatment option for patients with advanced or metastatic solid tumors that screen positive for high expression of Trop-2, nectin-4, or HER2, respectively.
The purpose of this study is to learn about the safety and effects of the study vaccine for the possible prevention of influenza. Influenza is a disease that can spread easily from one person to another and cause body aches, fever, cough, and other symptoms. The study vaccine is called Pandemic Influenza modRNA (pdmFlu) Vaccine. This study is seeking for participants who are: * between the ages of 18 to 49 years old or 65 to 84 years old. * willing and able to follow with all scheduled visits, treatment plan, laboratory tests, lifestyle changes, and other study procedures. * healthy as confirmed by medical history, physical examinations, and the study doctor. * capable of signing informed consent. Participants will receive either: * the pdmFlu vaccine, * a licensed influenza vaccine * a placebo. A placebo does not have any medicine in it but looks just like the study medicine. Participants will not know which vaccine they receive. Participants will receive the study vaccines as a single shot in the arm. The study will compare participant experiences to help understand if the pdmFlu vaccine is safe and effective. Participants will take part in this study for up to 13 months. During this time, the participants will receive the study vaccine and take part in follow-up visits.
The purpose of this study is to understand the safety and effects of a combined influenza and COVID-19 vaccine. This combined vaccine is compared to separate vaccines for the protection against influenza and SARS-CoV-2. Influenza and COVID-19 are diseases that can spread easily from one person to another and cause body aches, fever, cough, and other symptoms. Giving both influenza and COVID-19 vaccines together against influenza and SARS-CoV-2 could provide great benefits to both patients and caregivers in terms of simple and easy care. Around 8550 participants will be assigned into 1 of 8 vaccination groups (Group A, B, C, D, E, F, G or H) by chance. Cohort 1: Approximately 450 participants will be assigned by chance to one of the following: * Group A:Influenza and COVID-19 combination A vaccine, given at the same time in one arm and placebo (an injection consisting of just salt water and no medicines in it) in the opposite arm. * Group B: COVID-19 vaccine, given at the same time to one arm and licensed influenza vaccine in the opposite arm. Cohort 2: Approximately 4500 participants will be assigned by chance to one of the following: * Group C: Influenza and COVID-19 combination B vaccine, given at the same time in one arm and placebo in the opposite arm. * Group D: COVID-19 vaccine, given at the same time in one arm and licenced influenza vaccine in the opposite arm. Cohort 3: Approximately 3600 participants will be assigned by chance to one of the following: * Group E: Influenza and COVID-19 combination B vaccine. * Group F: COVID-19 vaccine. * Group G: Licenced influenza vaccine. * Group H: Investigational influenza vaccine. All participants in cohort 1 and cohort 2 will receive 2 injections and participants in cohort 3 will receive 1 injection as per their assigned study group at Visit 1. The participants will be followed for about 6 months. During this time, researchers will assess safety and the body's reaction to the vaccination over approximately 6 months. This will help understand if the study medicine is safe.
The study will determine if Therapeutic Plasma Exchange removes RNA biomarkers associated with Alzheimer's Disease and how quickly those biomarkers reappear after treatment.
This is a randomized, dose-escalation Phase I/IIa trial to evaluate safety, tolerability, immunogenicity and efficacy of an investigational RNA-based vaccine (BNT165e) for prevention of P. falciparum malaria in healthy malaria-naive adults. The multi-antigen malaria vaccine (designated BNT165e) is a combination of three distinct RNAs, BNT165c and BNT165d (composed of BNT165d1 and BNT165d2), encoding P. falciparum antigens encapsulated in lipid nanoparticles. The BNT165c RNA encodes the full Plasmodium falciparum circumsporozoite protein. The BNT165d1 and BNT165d2 RNAs both encode conserved, immunogenic segments of liver stage-expressed proteins.

2,000 individuals, aged 50-80 who have received a lung-RADS category 3 or 4 result on a LDCT screening study and who are scheduled for follow-up diagnostic imaging study, biopsy, clinical consultation or surgical appointment at one of the participating hospitals.
The purpose of this clinical study is to learn about the safety, extent of the side effects (reaction to vaccine), and immune response (your immune system's reaction) of the study vaccine called Varicella Zoster Virus modRNA (VZV modRNA). We are seeking for healthy participants 50 through 85 years of age. This study will be conducted in 2 substudies: Substudy A (Phase 1) and Substudy B (Phase 2). Substudy A: This substudy is the Phase 1 portion of the study. In this substudy, participants will receive 1 of 3 VZV modRNA vaccine candidates (different construct, different dose levels and different formulation \[frozen or freeze dry powder\]) or the approved shingles vaccine intramuscularly. Participants will be assigned in 1 of 10 groups in the study. Vaccination will be given either as a 2-dose series using one of two dosing schedules (either 2-months apart or 6-months apart), or (in one of the groups), as a single VZV modRNA vaccine at the first vaccination visit and saline at the second vaccination visit. Participants will take part in this study for 8 to 12 months depending on the group they are assigned to. Some group(s) will continue into persistence-of-immunity (overtime assessment of effect of vaccine) portion of the study. Those participants assigned to these selected groups will be involved in the study for up to 5 years. Substudy B: This substudy is the Phase 2 portion of the study. In this part of the study, participants will receive either VZV modRNA vaccine at selected dose level/schedule/formulation or approved shingles vaccine. This selection was determined from data collected in Substudy A. Participants will be involved in this study for up to 5 years.
The Investigators have demonstrated in preclinical studies that RNA liposomes activate APCs, induce antigen-specific T cell immunity, and can supplant DCs in a cell therapy model for HGG and have shown feasibility and activity of this approach in preclinical models and in canine patients with a spontaneous malignant glioma. In one arm of this study, we will investigate the safety and immunologic activity of RNA-LP vaccines in pediatric patients with recurrent pHGG. The investigators have also shown that intravenous administration of tumor mRNA loaded lipid particles (LPs) localizes primarily to lung, transfect antigen presenting cells (APCs) and lead to an activated T cell response for induction of anti-tumor immunity. In contrast to other formulations, RNA-LPs recruit multiple arms of the immune system (i.e. innate/adaptive), and remodel the systemic/intratumoral immune milieu, which remain potent barriers for vaccine, cellular, and checkpoint inhibiting immunotherapies. After only a single RNA-LP vaccine, the bulk of systemic and intratumoral dendritic cells (DCs) in mice display an activated phenotype; these activated DCs (harvested from tumors) expand antigen specific T cell immunity. In immunologically resistant pulmonary osteosacroma murine tumor models (i.e. K7M2), RNA-LPs induce robust anti-tumor efficacy in settings where immune checkpoint inhibitors (i.e. anti-PD-L1 therapy) do not confer therapeutic benefit. The investigators have already demonstrated safety of RNA-LPs in acute/chronic murine toxicity studies, and in client-owned canine trial. In this study, we will investigate the manufacturing feasibility, safety and immunologic activity of RNA-LP vaccine in patients with recurrent pulmonary or unresectable osteosarcoma and recurrent pHGG.
All participants will undergo baseline biopsies of subcutaneous abdominal adipose tissue for cellular/molecular profiling via snRNA-seq and metabolic/physiological assessments (insulin sensitivity, glucose tolerance, and β-cell function). Older obese participants will be randomized into three arms: lifestyle intervention (n=24), senolytics (n=24), or placebo (n=24).
