NCT07649096
This is a Phase 1, first-in-human, double-blind, placebo-controlled, adaptive-design, single-site study, involving dose exploration cohorts. During Part A, up to 4 cohorts, each consisting of approximately 14 healthy adult study participants, will be randomly allocated to receive either FZ002 or placebo. Part A is designed to begin with Cohort 1 evaluating the highest proposed dose of study product. This is intended to represent the "ceiling" (highest level) of the ranges of doses to be evaluated in the study. In the event of a safety or tolerability concern in Cohort 1, a dose de-escalation will be evaluated in Cohorts 2-4 until a safe and well-tolerated dose is identified. If no safety or tolerability concerns are identified at the completion of a cohort, the study will proceed to Part B with the approval of the independent Safety Monitoring Committee (SMC). This adaptive design allows for the progression of the study from Part A to Part B without necessarily progressing through all 4 cohorts in Part A if there is a lack of safety or tolerability concerns. During Part B, an initial 'sentinel' Cohort 5 "some-risk" adult study participants will be randomly allocated to receive a single daily dose of FZ002 or placebo for 28 consecutive days. This is intended to represent the "floor" (lowest level) of doses to be evaluated in the study. A Protocol Safety Review Team (PSRT) will review the available safety data from the first 7 days of Cohort 5. If there is a lack of safety or tolerability concerns over the first 7-days of dosing for Cohort 5, then Cohort 6 will be opened for enrollment. Cohort 6 "some-risk" adult study participants will evaluate the "floor" and "ceiling" dose of FZ002 versus placebo. The primary objective is to evaluate safety and clinical tolerability of oral doses of FZ002 or placebo when taken for up to 28 days.

Latinas continue to be affected disproportionally by HIV in the United States (US). Often, Latinas are not aware of their HIV status. Also, their perception of low risk for HIV interferes with condom use, HIV testing and lack of awareness, access, and use of Pre-exposure Prophylaxis (PrEP). About 60% of total HIV cases in NC occur among women of childbearing age, thus vulnerability to HIV is particularly acute among Latinas between ages 18 and 44 years old, an age group with the highest rate of new HIV infections in NC. These disparities indicate that HIV prevention among Latinas is urgent; therefore, the investigators propose an innovative intervention - a filmed dramatized story (telenovela/soap opera) Infección de Amor (IA) (Love Infection) - culturally tailored for Latinas in the US and delivered online. Infección de Amor was filmed and developed but has not been tested with the target audience. The proposed study will pilot test IA and move the intervention to online using a website that will allow individual access around the clock from any location and device, such as a smartphone, ensuring wide dissemination of the intervention in the future. This is a a two-year planning grant (R34) to prepare for an R01 efficacy trial. The aims are to: 1) Develop the intervention delivery website, conduct a website usability test, and test the feasibility and acceptability of the IA intervention (four telenovela episodes) with 10 Latinas, 2) Conduct a randomized controlled pilot study to examine change in HIV prevention behaviors (condom use; HIV testing; and PrEP awareness, access, and use) comparing intervention and control Latinas from baseline (Time 1 \[T1\], 0 months) to post-active intervention (Time 2 \[T2\], 1 month), and to six months follow-up, a period with no contact from the study staff (Time 3 \[T3, 7 months\]), and 3) Complete establishing the study infrastructure, expanding the multidisciplinary team, building the research partnerships with the community, finalize the protocol and training materials, refine recruitment and retention strategies, data collection and data management procedures, and obtain institutional review board approval in preparation for an R01 efficacy study. This study address the National Institute on Drug Abuse (NIDA) goal #4: increase NIDA research and programs' public impact. This is a novel intervention to advance HIV prevention for Latinas. This study implement a culturally durable and feasible intervention for Latinas.
NCT07209917
Cervical cancer (CC) remains one of the most common malignancies among women in India, with nearly 100,000 women diagnosed annually and over 60,000 preventable deaths annually. With high-risk human papillomavirus (HR-HPV) as the causative agent for CC, one risk factor that places women at high risk for CC is human immunodeficiency virus (HIV), as impaired immune response against Human papillomavirus (HPV) may result in persistent HR-HPV infection, a critical risk factor for progression of HPV-related cervical oncogenesis. Progression of precancerous lesions among women living with HIV (WLH) is also associated with: 1) lack of HPV screening; 2) high levels of depressive symptoms and stigma; and 3) malnutrition, which negatively impacts the activation and proliferation of immune cells. Yet programs that offer WLH with comprehensive services focused on HPV screening and psychological and nutritional support are almost non-existent, and the gap is critical. Nutrition plays an integral role in relationship to HPV/HIV co-infection, as demonstrated by an increased risk of HR-HPV associated with poor nutrition; nutritional deficiencies are likewise linked to cervical intra-epithelial neoplasia. The immunological effect of malnutrition may also be exacerbated among WLH due to elevated energy demands of chronic immune activation; worsened with HPV/HIV co-infection. Further, depressive symptoms (aka depression for brevity) partially mediate the effect of food insecurity on HIV viral suppression. In our completed ASHA-Nutrition R01 study of antiretroviral (ART) adherence, the investigators trained lay community health workers, named Accredited Social Health Activist (ASHA), to improve the health of 600 rural WLH by providing emotional support, skill-building, nutrition education, and/or protein-enriched food supplements. In that study, our intervention, co-delivered by our trained ASHA, and guided by nurses, led to increased CD4+ T cell recovery and improved anthropometric and psychosocial outcomes. The investigators found that ASHA support plus protein supplements and nutritional education were significantly associated with improved CD4 counts and increased lean mass at 18 months (P \< 0.001), as well as significant improvements in depression, ART adherence, social support and internalized stigma. In our sub study, CC screening of 598 of these WLH revealed that 13% were found to have abnormal cervical lesions and 4 (1%) had squamous CC. Preliminary evidence also revealed that nutritional supplements may be associated with a 40% reduction in the risk of abnormal cervical lesions (adjusted odds ratio \[aOR\] = 0.60), with an association between serum albumin and reduced risk of abnormal lesions (aOR= 0.39). With a focus on secondary prevention of CC, the investigators hope to mitigate the link between HR-HPV persistence and risk of CC as well as improve the health of women co-infected with HPV/HIV (W-Co-V). Our stellar team plans to build upon our prior ASHA-Nutrition intervention, using formative research to refine a nurse-led, ASHA co-delivered, nutrition-enhanced SAKHI HPV intervention, adapted for W-Co-V. This will be followed by a randomized controlled trial (RCT), assessing the efficacy of our refined comprehensive, multifaceted SAKHI HPV intervention, as compared with an enhanced Standard of Care (SOC+) (usual care + 3 sessions \[wellness, basic nutrition and HPV/HIV health promotion\]) among 348 high-risk co-infected women to prevent CC while remaining engaged in the HIV treatment cascade, and managing nutritional health. Recruited participants will be individually randomized in a 1:1 ratio into the two study arms. Our Primary outcome is HR-HPV persistence (2 positive tests for the same HR-HPV type, separated by 12-18 months). The two aims incorporating RCT interventions are as follows: Aim 2. To evaluate the efficacy of SAKHI HPV intervention among 348 W-Co-V on the primary outcome (HR-HPV persistence) as compared to the Enhanced Standard of Care (SOC+) program. H2: Compared to the SOC+ participants, SAKHI participants will have lower rates of HR-HPV persistence. Aim 3. Assess the impact of the SAKHI program secondarily on: 1) HIV indices (HIV viral load; CD4 count); 2) Nutritional index (serum albumin) at 6-, 12-, and 18-months.
NCT07666464
Intrapleural enzyme therapy (IET) is regarded by recent guidelines as a "rescue" therapy for managing complicated pleural infections; however, it is associated with significant side effects, including pleural bleeding, pain, and fever. Pleural irrigation with saline may serve as an alternative, yet evidence supporting its effectiveness is limited to a single small- scale, single-center randomized trial. The objective of the study is to compare the risk of treatment failure at 30 days (defined as a composite outcome that includes death, the need for thoracic surgery, or additional intrapleural enzyme therapy) between an early pleural irrigation strategy and standard care for complicated pleural infections.
NCT07655050
Retrograde intrarenal surgery (RIRS) is a widely used treatment for kidney stones; however, postoperative infectious complications remain a significant concern. This prospective randomized factorial trial aims to evaluate whether gentamicin-containing irrigation fluid and the use of a suction ureteral access sheath can reduce postoperative fever, systemic inflammatory response syndrome (SIRS), and sepsis after RIRS. The study will also investigate the independent and combined effects of these two interventions on infectious outcomes.

The purpose of this study is to compare the efficacy of a lock taurolidine-citrate solution vs standard saline solution for primary prevention of central venous catheter-associated bloodstream infection in adult patients treated with intra-venous therapy for a solid tumor
NCT05189925
Background: CGD is caused by a gene mutation. For people with CGD, their cells cannot kill germs well, so they can get frequent or life-threatening infections. Researchers want to see if a new procedure can help a person s cells kill germs for a short time. It uses messenger RNA (mRNA) to deliver correct instructions for the gene mutation to the cells. Objective: To test a procedure in which mRNA is added to a person s blood cells. Eligibility: Males aged 18-75 with CGD with a mutation in the gene that makes the protein gp91phox. Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Swab to test for strep throat Some screening tests will be repeated during the study. Participants will be admitted to the NIH Clinical Center hospital for at least 7 days. They will have apheresis. For this, a medicine is injected under their skin to prepare their white blood cells for collection. An IV line is placed into an arm vein. Blood goes through the IV line into a machine that divides whole blood into red blood cells, plasma, and white blood cells. The white blood cells are removed, and the rest of the blood is returned to the participant through an IV line in their other arm. The next day, they will get their mRNA-corrected cells via IV. They will be monitored for 3 more days. After discharge, participants will keep a symptom diary. They will be contacted weekly for one month, and then once a month. They will have a follow-up visit 3 months after the infusion.
NCT05762991
The aim of this study is to evaluate the impact of artificial intelligence (AI) assistance during routine upper endoscopy on gastric cancer-specific mortality. We hypothesize that AI-assisted endoscopic interpretation can further reduce gastric cancer-related mortality through two mechanisms: (1) improved detection of H. pylori infection, facilitating timely eradication therapy and subsequent prevention of gastric carcinogenesis; and (2) earlier identification of premalignant gastric conditions, enabling appropriate surveillance endoscopy and earlier detection of gastric cancer. The primary endpoint is gastric cancer-specific mortality.

NCT07656077
The study aims to better characterize intestinal tissue-resident memory T cells (TRM) in people living with HIV-1 receiving suppressive antiretroviral therapy (ART). TRM cells are key components of tissue immunity and may contribute to HIV-1 persistence within the intestinal mucosa, a major viral reservoir. The phenotypic, transcriptomic, and functional characteristics of intestinal CD4+ and CD8+ TRM cells, their susceptibility to HIV-1 infection, and their potential role as viral reservoirs will be investigated. Blood samples and additional colonic biopsies obtained during routine clinically indicated colonoscopy will be collected from HIV-1-infected participants and HIV-seronegative controls.
NCT00001230
This study will evaluate and treat patients with filarial infections to explore in depth the immunology of the disease, including susceptibility to infection, disease development, and response to treatment. Filarial infections are caused by parasitic worms. The immature worm (larva) is transmitted to a person through a mosquito bite and grows in the human body to 2 to 4 inches in length. Although many of these infections do not produce symptoms, especially in the early stages of infection, others can have serious consequences, including swelling of the limbs or genitalia, allergic-lung problems, skin rash, eye inflammation that can lead to blindness, and heart disease. This protocol does not involve any experimental diagnostic procedures or treatments, and will use only procedures employed in the standard practice of medicine. Persons between 3 and 100 years of age diagnosed with or suspected of infection with Wuchereria bancrofti, Bugia malayi, Onchocerca volvulus, Loa loa, or other parasitic worms may be eligible for this study. Participants will have routine tests to determine the specific type of filarial infection. These may include special tests of the lungs, skin or heart, depending on the type of parasite suspected. Patients with skin reactions may have a "punch biopsy" to examine a small piece of affected skin. For this procedure, an area of skin is numbed with an anesthetic and a small circular area, about 1/3-inch in diameter and 1/2-inch thick, is removed using a sharp cookie cutter-type instrument. Some patients may require bronchoalveolar lavage. For this procedure, the mouth and throat are numbed with lidocaine jelly and spray and, if needed, a sedative is given for comfort. A small plastic tube is placed in a vein to give medications. A pencil-thin tube is then passed through the nose or mouth into the lung airways to examine the airways. Salt water is injected through the bronchoscope into the air passage, acting as a rinse. A sample of the fluid is then withdrawn and examined for infection, inflammatory cells and inflammatory chemicals. (Bronchoalveolar lavage is done only if medically necessary and only on patients 21 years or older.) Once the diagnosis is established, standard treatment will be instituted with either diethylcarbamazine or ivermectin, depending on the type of infection. Additional procedures for research purposes include: * Extra blood draws to study immune cells and other immune substances. (This is the only research procedure that will be done in - More frequent and extensive follow-up evaluations than usual for routine care. They will include physical examination and blood studies. * Urine collections at specified periods, possibly including 24-hour collections. * Skin tests to examine the body s reaction to allergens-common environmental substances, such as cat dander or pollen-that cause an allergic reaction. The test is done in one of two ways: either the skin is lightly scratched and an allergen extract is placed over the just-broken skin, or a very fine needle is used to inject a small amount of allergen under the skin. In both methods, the site is monitored for swelling or hives in the next 48 hours. * Leukapheresis (only on patients 21 or older ) to collect quantities of white blood cells. Whole blood is collected through a needle in an arm vein, similar to donating blood. The blood circulates through a machine that separates it into its components, and the white cells are removed. The rest of the blood is returned to the body, either through the same needle or through another needle in the other arm.
NCT07524062
This study investigates whether infrared thermography, a harmless and non-invasive thermal camera technique, can help monitor how surgical wounds heal after skin surgery. The goal is to detect wound problems earlier, such as infection or delayed healing, and to support doctors in making timely clinical decisions.
