Pharmacokinetics and Safety of Commonly Used Drugs in Lactating Women and Breastfed Infants
Summary: Over half of women in the US who are breastfeeding their infants take prescription drugs. You are being asked to participate in this study because you are breastfeeding your infant and are currently taking, as part of your medical care, at least one of the drugs we are studying. We are interested in studying drugs commonly prescribed to women who are breastfeeding so we can learn more about the am...
A Phase I Pharmacokinetic and Safety Assessment of Oral Letermovir in Infants With Symptomatic Congenital Cytomegalovirus Disease
Summary: This is a Phase 1 single-arm open-label study of letermovir in neonates with symptomatic congenital Cytomegalovirus (CMV) disease. There will be two groups enrolled. Group 1 will be comprised of 4 subjects. Following documentation study inclusion and signing of informed consent, Group 1 subjects will receive one dose of oral letermovir (Study Day 0), using the dose bands. A full pharmacokinetics (...
A Biomarker Study in Men With Localized Prostate Cancer Treated With Aglatimagene Besadenovec
Summary: Phase 2a, open-label, multi-center study evaluating biomarkers and biodistribution of aglatimagene besadenovec plus valacyclovir in men with localized, favorable intermediate-risk prostate cancer who are planning to receive external beam radiation therapy (EBRT).
Natural History Study of the KSHV Inflammatory Cytokine Syndrome (KICS)
Background: \- KSHV inflammatory cytokine syndrome (KICS) is a newly recognized disease caused by Kaposi sarcoma-associated herpesvirus (KSHV). This virus can cause cancer. People with KICS can have severe symptoms. They include fever, weight loss, and fluid in the legs or abdomen. People with KICS may also be at risk of getting other cancers associated with KSHV. These cancers include Kaposi sarcoma and lymp...
The Regulatory Mechanisms of Electroacupuncture Intervention on Immune Cells in Herpes Zoster
Summary: Herpes Zoster (HZ), caused by the Varicella-Zoster Virus (VZV), is a common infection characterized by localized pain and blistering, with higher incidence in females. HZ affects patients' physical health, mental well-being, and quality of life. The immune system is critical in HZ pathogenesis. Studies show acupuncture relieves pain, modulates immunity, and may lower postherpetic neuralgia (PHN) r...
Time-limited Triplet Combination of Pirtobrutinib, Venetoclax, and Obinutuzumab for Patients With Treatment-naïve Chronic Lymphocytic Leukemia (CLL) or Richter Transformation (RT)
Summary: To learn if the combination of pirtobrutinib (also called LOXO-305), venetoclax, and obinutuzumab is safe and effective when given to patients with chronic lymphocytic leukemia (CLL) or Richter transformation (RT) who have not previously received treatment.
A Phase 1b, Multicenter, Dose Escalation, Evaluation of Safety and Tolerability of ASP7317 for Geographic Atrophy Secondary to Age-related Macular Degeneration
Summary: Age-related macular degeneration (AMD) is an eye disease which causes people to lose their sharp central vision over time. Aging damages the macula, which is in the middle of the retina - the light-sensitive part at the back of the eye. There are 2 types of AMD - wet AMD and dry AMD. The advanced stage of dry AMD causes vision loss. This is known as geographic atrophy. AMD makes everyday tasks lik...
Letermovir/Valganciclovir Combination Versus Valganciclovir Monotherapy for Treatment of Cytomegalovirus (CMV) Infections in Kidney Transplant Recipients
Summary: The purpose of this study is to evaluate the efficacy and the tolerance of letermovir as part of dual antiviral therapy (in association with valganciclovir) in renal transplant recipients with CMV DNAemia, requiring valganciclovir treatment per investigator's judgment.
Individualization of Dosage Regimens in Obese Patients: Application to Acyclovir
Summary: The number of obese people will reach 50% of the world population by 2035. Obesity is a chronic disease. For obese patients, dosage regimens have been determined for patients with a normal BMI between 20-30 kg/m2. Based on plasma and urine concentrations, a pharmacokinetic model will be performed to study in healthy volunteers, the predictive character of lean mass, measured by DEXA, on renal elim...
Non-Inferiority Assessment of Valacyclovir Versus Valganciclovir as Prophylaxis Against CMV and EBV Viremia in Kidney Transplant Recipients: A Single-Center Prospective Randomized Pilot Study.
Summary: Opportunistic CMV viremia (primary infection or reactivation) is usually managed by taking prophylactic medication for both adult and pediatric kidney transplant patients. Most hospitals prescribe valganciclovir for this purpose but valacyclovir has also been used. The most unfavorable side effect of valganciclovir is bone marrow suppression which can be troublesome for kidney transplant patients ...
Efficacy and Safety of Leymovir Versus Valganciclovir in Prevention of Cytomegalovirus Infection and Cytomegalovirus Disease in Chinese Kidney Transplant Recipients
Summary: the existing anti-CMV drugs mainly include valganciclovir, ganciclovir and foscarnet sodium, all of which act on DNA polymerase (pUL54), making them prone to cross resistance. DNA synthesis in normal cell is also catalyzed by DNA polymerase, which can also inhibit normal cell production, especially in metabolically active bone marrow cells, leading to bone marrow suppression. In addition, these dr...
Individualised Dose Optimisation of Ganciclovir in Immunocompromised Children Trial (ID-MAGIC)
Summary: This study is being conducted at seven major children's hospitals in Australia and New Zealand to test a new approach for treating a virus, called cytomegalovirus in children with weakened immune systems. The researchers want to find out if using a web app to customise the dose of a medication called ganciclovir is better at clearing the virus over a six-week period compared to the standard method...
