102 Clinical Trials for Various Conditions
Background: * National Institutes of Health (NIH) researchers have been studying immune cells (white blood cells) to better understand how the human body s defense system works and adjusts or regulates itself, and how changes in this system can make a person sick. * To study the cells of patients who have problems with their immune systems, researchers would like to collect samples of skin cells from patients with immune system disorders and compare them with skin cells taken from healthy volunteers. By studying these cells, researchers hope to determine whether these cells can be modified to create a new kind of personalized gene therapy that would attempt to cure immune diseases in the future. Objectives: * To obtain skin cells from patients with immune system disorders and from healthy volunteers for research and comparison purposes. Eligibility: * Patients between the ages of 2 and 85 who have immune system disorders. * Healthy volunteers between the ages of 18 and 85. * Both groups will be selected from the eligible participants of existing NIH studies into immune system disorders. Design: * Researchers may take up to two biopsies from participants arms, legs, abdomen, or back. * The biopsy site will be numbed with local anesthetic and cleaned before the sample is taken. * The punch skin biopsy needle will be inserted into the skin and rotated to remove a small circle of skin (approximately 1/4 to 3/8 of an inch across). The area will be closed with bandages or stitches, and then covered with a dressing. Any stitches will be removed in 7 to 10 days. * Tissue samples collected in the study will be stored for future research.
Fibroblasts can be cultured from human skin biopsies using fetal bovine serum and artificial growth medium. Fibroblasts cultured in this way retain the genetic characteristics of their donor but can be used for experiments where study conditions are much more precisely controlled than they can be in in vivo studies. We plan to culture fibroblasts from Pima Indians for two purposes. Firstly, to look for an in vitro system to measure insulin resistance, the underlying abnormality in Pima diabetics. Secondly, to look for biochemical markers of diabetes or obesity in Pimas employing two dimensional electrophoresis techniques.
Background: Fibroblast-activation protein (FAP) is an enzyme that appears in high numbers in certain cancer cells. \[18F\]FAPI-74 is a new tracer-a substance that is injected into a person s body before an imaging scan. Researchers believe that \[18F\]FAPI-74 may be able to highlight FAP enzymes more effectively than approved tracers. If so, the new tracer would make it easier to find FAP-positive tumors in the body. Objective: To see if \[18F\]FAPI-74 PET scans are as good or better than other methods for detecting certain cancers. Eligibility: People aged 18 years or older with cancer in 1 of these places: the ducts of the pancreas, liver, gallbladder, or small intestine; stomach; bladder; ovaries; or adrenal glands. They must be enrolled in an NIH treatment study for their cancer. Design: Participants will have 2 baseline scans: 1 with \[18F\]FAPI-74; 1 with an approved tracer. The \[18F\]FAPI-74 will be infused through a tube attached to a needle inserted into a vein. About 1 hour later, the participant will undergo 1 or more imaging scans. Within 1 week, participants will undergo the same scanning procedures with the approved tracer. If the baseline scan with \[18F\]FAPI-74 shows the tumors, scans with this tracer will be repeated when their regular treatment regimen calls for scans again. If the scans with the regular tracer also showed tumors, this scan will be repeated within the same week as the repeated \[18F\]FAPI-74 scans. If either type of scan showed no tumors, that scan will not be repeated. If the participant s cancer progresses within 2 years, both types of scan may be repeated. Follow-up calls will continue for 2 years.
The purpose of the study is to investigate the impact of the injection of dermal filler on the quality of the skin dermal extracellular matrix in persons between the ages of 30-50 years. The quality of the dermal extracellular matrix will be assessed following injection of dermal filler compared to injection of saline vehicle.
This phase II trial tests whether 68Ga-FAPI-46 positron emission tomography (PET)/computed tomography (CT) scan works to image cancer-associated fibroblasts (CAFs) in patients with pancreatic ductal adenocarcinoma (PDA) that has not spread to other parts of the body (localized). CAFs are a type of connective tissue cell that are found within or near cancerous tissue. Many CAFs express a protein called fibroblast activation protein (FAP) that are not found on healthy cells in large amounts. 68Ga-FAPI-46 is a radioactive chemical compound designed to circulate through the body and attach itself to FAP on PDA cells. A PET/CT scan is then used to detect the location of FAP lesions. PET scan is a procedure in which a small amount of radioactive glucose (sugar) is injected into a vein, and a scanner is used to make detailed, computerized pictures of areas inside the body where the glucose is taken up. Because cancer cells often take up more glucose than normal cells, the pictures can be used to find cancer cells in the body. CT scan is a procedure that uses a computer linked to an x-ray machine to make a series of detailed pictures of areas inside the body. The pictures are taken from different angles and are used to create 3-dimensional (3-D) views of tissues and organs. Combining a PET scan with a CT scan can help make the image easier to interpret. PET/CT scans are hybrid scanners that combine both modalities into a single scan during the same examination. Giving 68Ga-FAPI-46 PET/CT may help doctors improve upon the diagnosis and management of PDA.
Background: Fibrous dysplasia (FD) is a disorder that affects bone growth. Affected bone tissue is weakened, and people with FD are prone to deformities, fractures, and other problems. People with FD may also have low blood phosphate levels. This can make bones even weaker. Better treatments are needed. Objective: To test a study drug (burosumab) in people with FD who have low blood phosphate levels. Eligibility: People aged 1 year or older who have FD and low blood phosphate levels. Design: Participants will visit the NIH 3 times in 48 weeks. Each visit will last 5 to 7 days. Participants will self-inject burosumab under the skin in their belly, upper arm, or thigh. They (or a caregiver) will do this at home 1 or 2 times a month. They will be trained in person on how to inject the drug. Home injections will be guided via telehealth. During NIH visits, participants will have a physical exam with blood and urine tests. They will have x-rays of different parts of their body. They will have a radioactive tracer injected into their vein; then they will have a bone scan. They will have tests to assess their strength, walking, and movement. They will complete questionnaires about their pain, mobility, and fatigue levels. Adult participants may have bone biopsies. These will be done under anesthesia with sedation. Small samples of FD-affected bone will be removed for study. Between NIH visits, participants will go to a local laboratory for blood and urine tests. Child participants will have an additional follow-up visit 2 weeks after the final NIH visit.
The primary objectives of this study are to observe the safety and tolerability of bemarituzumab and to evaluate preliminary antitumor activity.
The main objective of this study is to compare efficacy of bemarituzumab combined with oxaliplatin, leucovorin, and 5-fluorouracil (5-FU) (mFOLFOX6) to placebo plus mFOLFOX6 as assessed by overall survival (OS) in participants with FGFR2b ≥10% 2+/3+ tumor cell staining (FGFR2b ≥10% 2+/3+TC)
This study is a double blinded, placebo-controlled phase II study evaluating the efficacy of FGF-2 for the treatment of chronic non-healing tympanic membrane perforations (TMP). The documentation of TM closure will be the main efficacy outcome measure. Pretreatment photographs will document the area of the TM perforation and allow measurement of surface areas of the TMP for comparison of pre- and post-treatment. The study will be divided into two phases, the Randomized Treatment phase (part A), and the Unblinded Crossover phase (part B). In part A of the study, subjects will be randomized 1:1 (using simple randomization) to receive FGF-2 or placebo treatment up to 3 treatments. Subjects that fail three study treatments will move on to part B of the study. Subjects who received placebo in part A and failed three placebo treatments will crossover to receive unblinded FGF-2 for up to 3 treatments. Subjects who received FGF-2 in part A and failed three experimental treatments will not have additional FGF-2 treatment, and will move on to study follow up.
The study will enroll 20 adults ages 18-75 with a transtibial amputation with mature residual limbs who are ambulatory prosthesis users. Participants will be randomized to either treatment with low dose volar fibroblast injections (n=10) or to vehicle control (n=10). Participants will undergo a biopsy to harvest volar skin for fibroblast expansion and tattooing to identify injection sites on the residual limb. Fibroblasts will be processed at the Hopkins Cellular Therapy Core Lab and volar cells primed for injection will be sent to participating centers for administration. Participants randomized to the treatment group will be treated with low-dose cells. Injections will be administered on at least 1 and up to three separate days over the course of one week. Participants randomized to the vehicle control group will receive injection of cryoprotectant. All participants will be followed at 2 weeks, 1, 2, and 3 months after the last injection. These visits will include a clinical evaluation for complications, non-invasive assessments of skin firmness and thickness, skin appearance, and patient-reported outcomes. After the final monitoring visit, individuals randomized to the vehicle control group will have the opportunity to receive the volar fibroblast injections and will be followed for an additional 3 months. The investigators hypothesize that (1) There will be no difference in the rate of serious adverse events among patients treated with volar fibroblast injections compared with patients treated with vehicle control, and (2) Patients treated with volar fibroblast injections will have firmer skin on the residual limb compared with patients tread with vehicle alone.
This phase II trial studies the effect of rogaratinib in treating patients with sarcoma with a change in a group of proteins called fibroblast growth factor receptors (FGFRs) or SDH-deficient gastrointestinal stromal tumor (GIST). Rogaratinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
The purpose of this study is to evaluate the efficacy of erdafitinib in terms of overall response rate (ORR) in adult and pediatric participants with advanced solid tumors with fibroblast growth factor receptor (FGFR) alterations (mutations or gene fusions). It will also evaluate ORR in pediatric participants with advanced solid tumors and FGFR alterations.
The purpose of this non-interventional study is to identify participants with urothelial cancer (UC) and selected fibroblast growth factor receptor (FGFR) aberrations through molecular testing of their archival tumor tissue.
This study is a clinical trial testing the safety and efficacy of volar fibroblast (skin cells from the palm or sole) injections for thickening the epidermal (skin) layer at the stump site in people with below the knee amputations. The study will enroll adults seen at Johns Hopkins.
This is a two part study. In the first part, the pharmacokinetic profile of Epigallocatechin-3-gallate (EGCG) in normal human volunteers given a single oral dose will be determined to set the dose for the second part of the study. In the second part of this study, lung biopsy fragments and urine samples from patients with interstitial lung disease treated with EGCG will be evaluated in biochemical assays and compared to samples from untreated control patients.
The primary objective of this study is to determine the safety, tolerability, maximum tolerated dose (MTD) or recommended Phase 2 dose (RP2D) and efficacy of rogaratinib in combination with copanlisib in patients with locally advanced or metastatic solid tumors that are mRNA-positive for at least one FGFR1-4 subtype. The secondary objectives of this study are to characterize the pharmacokinetics (PK) of rogaratinib and copanlisib alone and in combination, and to assess the anti-tumor efficacy of rogaratinib in combination with copanlisib for locally advanced or metastatic solid tumors that are mRNA-positive for at least one FGFR1-4 subtype.
This is a randomized, open-label, multicenter Phase 2/3 study to evaluate the efficacy and safety of rogaratinib (BAY 1163877) compared to chemotherapy in patients with FGFR-positive locally advanced or metastatic urothelial carcinoma who have received prior platinum-containing chemotherapy. The primary objective is to demonstrate the superiority of rogaratinib over chemotherapy in terms of objective response rate (before: overall survivial) of urothelial carcinoma patients with FGFR positive tumors. At randomization, patients will have locally advanced or metastatic urothelial carcinoma and have received at least one prior platinum-containing chemotherapy regimen. Only patients with FGFR1 or 3 positive tumors can be randomized into the study. Archival tumor tissue is adequate for testing of FGFR1 and 3 mRNA expressions, which will be determined centrally using an RNA in situ hybridization (RNA-ISH) test. Approximately 42 % of UC patients with locally advanced or metastatic UC are identified as FGFR-positive by the RNA-ISH cut-off applied.
The purpose of this study is to evaluate efficacy of erdafitinib versus chemotherapy or pembrolizumab in participants with advanced urothelial cancer harboring selected fibroblast growth factor receptor (FGFR) aberrations who have progressed after 1 or 2 prior treatments, at least 1 of which includes an anti-programmed death ligand 1(PD-\[L\]1) agent (cohort 1) or 1 prior treatment not containing an anti-PD-(L) 1 agent (cohort 2).
Background: Age-related macular degeneration (AMD) is the leading cause of blindness in the United States. Currently, there is no safe way to obtain cells from the eye to study. But researchers now can turn other types of cells, like skin or blood, into induced pluripotent stem (iPS) cells. These can be grown in a lab and turned into other types of cells, like cells from the eye. This will allow researchers to understand and treat diseases of the eye such as AMD. Objectives: To establish a bank of samples that can be changed into other cell types, such as eye cells, to better understand diseases such as AMD. Also to test drugs in order to treat various eye diseases. Eligibility: People who provided DNA samples in another protocol (07-EI-0025) Design: Participants will be screened with their data from the previous protocol. Participants with select genetic variants will be chosen and contacted via phone. Participants will have a punch skin biopsy. The skin will be washed. A numbing medication will be injected. A small piece of skin will be removed with a biopsy tool. The site will be covered with a dressing. They will receive instructions on how to care for the area. They will have follow-up visits if needed for clinical care for the area. Participants may be asked to return if their first sample did not provide enough cells for the lab. Participants sample will be developed into eye cells. The cells will be used to understand diseases and test new drugs.
To evaluate the safety, tolerability, maximum tolerated dose, pharmacokinetics, and pharmacodynamics of the anti-FGFR2 antibody drug conjugate BAY1187982 in subjects with advanced solid tumors known to express fibroblast growth factor receptor 2 (FGFR2)
A Phase II randomized trial will be initiated to evaluate closure of the perforated tympanic membrane as the primary measureable outcome. The goal is to determine the safety and efficacy of Fibroblast Growth Factor-2 (FGF-2) in the closure of chronic tympanic membrane perforations (TMP). If FGF-2 is topically applied for the treatment of chronic TMP in humans, it is hypothesized it will be safe, tolerable and effective for use as treatment for tympanic membrane perforation. A total of 60 subjects will be recruited.
Hypothesis The incidence of toxicity in patients receiving the tumor DNA-transfected fibroblast vaccine will be acceptably low and the immunologic response rate sufficiently high to warrant further study of this therapy The study of the vaccine will proceed in two stages after the method of Simon (102). In the first stage, 15 patients will be accrued and treated. If two or fewer objective immunologic responses occur, the study will be terminated. If 3 or more responses are observed, the study will proceed to the second stage, accruing an additional 22 patients. If the second stage is complete and a total of 9 or more immunologic responses are observed among the 37 patients treated, the treatment response rate for the vaccine will be considered high enough to warrant further study. Conversely, if the evaluation of the vaccine concludes at the first stage, or if 8 or fewer total immunologic responses occur after completing the second stage, the vaccine will not be considered for further study.
The objectives of the study are to: * Identify a dose and dosing regimen of burosumab, based on safety and pharmacodynamic (PD) effect, in pediatric XLH participants * Establish the safety profile of burosumab for the treatment of children with XLH including ectopic mineralization risk, cardiovascular effects, and immunogenicity profile * Characterize the pharmacokinetic (PK)/PD profile of the KRN23 doses tested in the monthly (Q4) and biweekly (Q2) dose regimens in pediatric XLH patients * Determine the PD effects of burosumab treatment on markers of bone health in pediatric XLH patients * Obtain a preliminary assessment of the clinical effects of burosumab on bone health and deformity, muscle strength, and motor function * Obtain a preliminary assessment of the effects of burosumab on participant-reported outcomes, including pain, disability, and quality of life in pediatric XLH patients * Evaluate the long-term safety and efficacy of burosumab
The objectives of this study are to determine the tolerability, safety, pharmacokinetics (PK), pharmacodynamics (PD), and efficacy of oral ASP5878 in participants with solid tumors.
Phosphorus-based food additives are commonly used by food manufacturers for many applications, such as enhancing flavor, in ready-to-eat foods and beverages. While these additives can significantly increase an individual's daily phosphorus intake, little is known about the effect of dietary phosphorus on kidney health. In this study, the investigators will first lower baseline phosphorus intake to about 1000mg/d by educating participants to avoid foods with phosphorus additives. Then, participants will be randomized to a higher phosphorus period (\~2gm/d) and a lower phosphorus period (\~1gm/d) by providing unaltered, commercially-available food/beverage products with and without phosphorus additives. The investigators hypothesize that participants will have higher urine albumin excretion and fibroblast growth factor-23 (FGF-23) during the higher phosphorus period compared to the lower phosphorus period.
* This was the first study where BAY1163877 was given to humans. Impact of the study was to evaluate if patients with advanced solid cancers show advanced clinical benefit under the treatment with the pan FGFR inhibitor. Patients (all comers) received the study drug treatment in a dose-escalation scheme (no placebo group) to determine the safety, tolerability and maximum tolerated dose (MTD) of BAY1163877. The relative bioavailability of liquid service formulation and tablets was determined. * After the MTD was defined patients with solid tumors (all comers), lung cancer (lung adenocarcinoma \& squamous non-small cell lung cancer), head and neck cancer or bladder cancer was enrolled according to their FGFR expression profile (biomarker stratification). * The study also assessed the pharmacokinetics, biomarker status, pharmacodynamic parameters and tumor response of BAY1163877. * BAY1163877 was given twice daily as oral application. Treatment was stopped if the tumor continued to grow, if side effects, which the patient cannot tolerate, occurred or if the patient decided to exit treatment.
This research is being done to determine if investigators can change skin from one type to another. Specifically, investigators are interested in making normal skin into the thicker skin found on our palms and soles.
This study is primarily designed to assess the safety and the tolerability of Debio1347 (CH5183284) in patients with advanced solid malignancies, whose tumours have an alteration of the Fibroblast Growth Factor Receptor (FGFR) 1, 2 or 3 genes, for whom standard treatment does not exist or is not indicated. The main objective of Part A is to identify the dose-limiting toxicities (DLTs) and estimate the maximum tolerated dose (MTD) based on the safety and tolerability of Debio1347 orally administered daily to these patients, in order to determine the recommended dose. The main objective of Part B is to evaluate the safety profile at the recommended dose, in a larger cohort of these patients.
The purpose of this research is to better understand how calcium and glucose may play a role in people developing diabetes. By doing this study, the investigator hopes to learn whether abnormal calcium and glucose responses in skin biopsies from healthy patients and patients with Type 2 diabetes can identify and predict patients at greatest risk for later complications.
This phase IB trial aims to identify anticancer activity of GSK3052230 in subjects with malignancies with abnormal dependence on FGF pathway signaling. Combination doses of GSK3052230 with standard of care chemotherapy in the first and second line or greater setting of metastatic squamous non-small cell lung cancer (NSCLC) and first line malignant pleural mesothelioma subjects will be studied in the 3+3 dose-escalation design. This will be a multi-arm, multicenter, non-randomized, parallel-group, uncontrolled, open-label Phase IB study designed to evaluate the safety, tolerability and preliminary activity of GSK3052230 in combination with paclitaxel + carboplatin (Arm A), in combination with docetaxel (Arm B), or in combination with pemetrexed + cisplatin (Arm C). Approximately 70 subjects will be enrolled in the study (approximately up to 120 may be enrolled).
