The primary objectives of this study are to compare sacituzumab tirumotecan to Treatment of Physician's Choice (TPC) with respect to progression-free survival (PFS) per response evaluation criteria in solid tumors (RECIST 1.1), as assessed by blinded independent central review (BICR), and overall survival (OS). The primary hypotheses are that sacituzumab tirumotecan is superior to TPC with respect to PFS per RECIST 1.1, as assessed by BICR, and that sacituzumab tirumotecan is superior to TPC with respect to OS.

This study will evaluate and gather information in patients with genetic causes of too much androgen (male-like hormone) in order to better understand the effects of too much androgen and describe problems associated with it. Too much androgen in childhood, if untreated, results in rapid growth and early puberty with early cessation of growth and short stature in adulthood. Too much androgen in adulthood may result in infertility, and women may have excess facial hair, acne and a more male-like appearance. Excess androgen may also affect mood and behavior and possibly the secretion of other hormones, such as insulin. Two genetic diseases that result in early childhood androgen excess are congenital adrenal hyperplasia (CAH) and familial male-limited precocious puberty (FMPP). Patients with known or suspected CAH due to 21-hydroxylase deficiency, 11- hydroxylase deficiency, or 3-beta-hydroxysteroid dehydrogenase deficiency and males with known or suspected FMPP may be eligible for this study. Patients with both classic and non-classic CAH are eligible, and patients with androgen excess of unknown cause may be eligible. Participants undergo the following procedures: Medical history and physical examination. Fasting blood tests for analysis of hormones, blood chemistries including blood sugar and cardiovascular risk factors such as lipids. Oral glucose tolerance test for patients with elevated insulin levels. For this test, a catheter (plastic tube) is placed in a vein in the patient's arm. The patient drinks a sugar-containing fluid and blood samples are collected through the catheter at intervals starting with drinking the solution, and then 30, 60 and 120 minutes after drinking the solution. 24-hour urine collection to measure hormone levels in the urine. DNA testing for patients with 21-hydroxylase deficiency to help identify the type of genetic mutation responsible for the disease. X-ray of the left hand to measure bone age in growing children. The x-ray is used to determine how far into puberty the child is and how much growth potential is left in the bones. A pelvic ultrasound in females and testicular ultrasound in males to evaluate the size and development of the gonads (ovaries in females and testes in males). Cognitive and psychological tests, including an IQ test and evaluation of memory, achievement and behavior. Other tests and evaluations based on medical need. The schedule for these procedures varies. In a part of the study involving only patients with CAH, growing children are evaluated twice (once in childhood and once after reaching adult height), and adults are evaluated once. In another part of the study involving patients with CAH and FMPP, growing children are seen twice a year, and adults and children who have reached adult height may be seen annually. Additional visits may be scheduled if medically indicated. In this part of the study, females are asked to keep a record of their periods after their first menstrual cycle. Read Less

The purpose of this single-arm interventional study is to evaluate the long-term safety, efficacy, and durability of the Symplicity Spyral system in subjects treated with renal denervation. Additionally, long-term follow-up data will also be collected from eligible subjects previously treated in the SPYRAL PIVOTAL-SPYRAL HTN-OFF MED and SPYRAL HTN-ON MED studies. Read Less

This is a 2-arm, randomized, open-label, multicenter, global, Phase 3 trial to evaluate the efficacy, safety, and tolerability of tovorafenib monotherapy versus standard of care (SoC) chemotherapy in patients with pediatric low-grade glioma (LGG) harboring an activating rapidly accelerated fibrosarcoma (RAF) alteration requiring front-line systemic therapy.

This phase II trial studies the best approach to combine chemotherapy and radiation therapy (RT) based on the patient's response to induction chemotherapy in patients with non-germinomatous germ cell tumors (NGGCT) that have not spread to other parts of the brain or body (localized). This study has 2 goals: 1) optimizing radiation for patients who respond well to induction chemotherapy to diminish spinal cord relapses, 2) utilizing higher dose chemotherapy followed by conventional RT in patients who did not respond to induction chemotherapy. Chemotherapy drugs, such as carboplatin, etoposide, ifosfamide, and thiotepa, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays or high-energy protons to kill tumor cells and shrink tumors. Studies have shown that patients with newly-diagnosed localized NGGCT, whose disease responds well to chemotherapy before receiving radiation therapy, are more likely to be free of the disease for a longer time than are patients for whom the chemotherapy does not efficiently eliminate or reduce the size of the tumor. The purpose of this study is to see how well the tumors respond to induction chemotherapy to decide what treatment to give next. Some patients will be given RT to the spine and a portion of the brain. Others will be given high dose chemotherapy and a stem cell transplant before RT to the whole brain and spine. Giving treatment based on the response to induction chemotherapy may lower the side effects of radiation in some patients and adjust the therapy to a more efficient one for other patients with localized NGGCT.

Background: - Some people with advanced heart and lung disease have heart and lung transplants. But the organs are often rejected. When this happens, the organ recipients must have repeated biopsies. These are invasive and expensive. Researchers want to see if a blood test can predict rejection and take the place of biopsies. The test shows how much donor DNA is in a recipient s blood. Objective: - To see if a new blood test can be used instead of biopsies to diagnose rejection after transplant. Eligibility: - Adults 18 years and older who are on the lung or heart transplant waitlist. Design: Participants will have about 4 teaspoons of blood drawn from the arm before having their transplant. Researchers will collect demographic data about participants. They will also collect basic medical information about their condition. After surgery, while still in the hospital, participants will have 2 teaspoons of blood drawn twice a week until they go home. At each biopsy visit after the transplant, participants will have 4 teaspoons of blood drawn for testing for up to 5 years. Read Less

This is a multi-center, randomized, quadruple-blind, placebo-controlled study to evaluate the efficacy and safety of batoclimab in adult participants with active CIDP. The study includes an up to 4-week Screening Period, an up to 12-week Washout Period, a 12-week Randomized Treatment Period (Period 1), an up to 24-week Randomized Withdrawal Period (Period 2), an up to 52-week Long-term Extension (LTE) Period (optional), and Safety Follow-up 4 weeks after the last dose of study treatment. The total study duration will be up to approximately 109 weeks. Eligible participants will be assigned to one of four cohorts based upon their baseline CIDP treatment (Cohorts A and D - immunoglobulin [Ig] or plasma exchange [PLEX]; Cohort B - corticosteroids; Cohort C - naive or untreated in previous 3-24 months) and whether they meet diagnosis according to the European Academy of Neurology/Peripheral Nerve Society (EAN/PNS) criteria (Cohorts A, B, and C) or clinical criteria only (Cohort D) at the time of screening.

Background: Genetic testing called "sequencing" helps researchers look at DNA. Genes are made of DNA and are the instructions for our bodies to function. We all have thousands of genes. DNA variants are differences in genes between two people. We all have lots of variants. Most are harmless and some cause differences like blue or brown eyes. A few variants can cause health problems. Objective: To understand the genetics of immune disorders various health conditions, as well as outcomes of clinical genomics and genetic counseling services performed under this protocol. Eligibility: Participants in other NIH human subjects research protocols - either at the NIH Clinical Center (CC) or at Children s National Health System (CNHS) - (aged 0-99 years), and, in select cases, their biological relatives Design: Researchers will study participant s DNA extracted from blood, saliva, or another tissue sample, including previously collected samples we may have stored at the NIH. Researchers will look at participant s DNA in great detail. We are looking for differences in the DNA sequence or structure between participants and other people. Participants will receive results that: Are important to their health Have been confirmed in a clinical lab Suggest that they could be at risk for serious disease that may affect your current or future medical management. Some genetic information we return to participants may be of uncertain importance. If genetic test results are unrelated to the participant s NIH evaluations, then we will not typically report: Normal variants Information about progressive, fatal conditions that have no effective treatment Carrier status (conditions you don t have but could pass on) The samples and data will be saved for future research. Personal data will be kept as private as possible. If future studies need new information, participants may be contacted.... Read Less
