Liquid biopsy has been widely used in the diagnosis and treatment of tumors, and cfDNA has always been a hot spot in clinical research. Previous studies have shown that cfDNA may be associated with postoperative recurrence of gastric cancer, but it is rarely reported whether cfDNA is associated with the survival of gastric cancer. The purpose of this study was to assess the relationship between cfDNA and survival in advanced gastric cancer
Phase IIa, open clinical trial, pilot, single arm and proof of concept.
The threat of MRSA and multi-drug resistant pathogens have been growing in recent years. A new means of countering the infectious threat is required and one such modality is the use of UV light for disinfection. The aim of the study is to proof the efficacy of the 222nm UV light in disinfection on patients with sacral sores. This is a first in human proof-of-concept study
The aim of this trial is to investigate whether quantitative analysis of the total concentration of circulating free deoxyribonucleic acid (cfDNA) and of the cfDNA integrity index (DII) (Intplex®) may reflect hepatocellular carcinoma (HCC) tumor dynamics or response for patients treated by Sorafenib or Regorafenib and if it could be used as a tool for patient management under targeted therapy.
This study is a prospective, multicenter, observational study on metastatic, operable colorectal cancer to evaluate the proof of concept of the cfDNA analysis for the early detection of recurrences
The primary purpose of this proof of concept clinical study is to evaluate the efficacy and safety of the study drug, ACH-0144471, in participants who have been diagnosed with either C3GN or dense deposit disease (DDD) based on renal biopsy. Participants will be randomized 1:1 to receive either study drug ACH-0144471 or placebo for a period of 6 months.
Acute rejection (AR) is still one of the major complications after kidney transplantation. The current diagnosis measure for AR is primarily pathological puncture test and hematuria biomarker detection, yet due to their inferior performance on timeliness, the allograft kidneys usually have been in severe conditions when the diagnoses take place. Donor derived cell free DNA (dd-cfDNA) is utilized as a measure for "liquid biopsy", it can predict acute rejection at very early peri...
The effectiveness of current checklists is hampered by lack of acceptance and compliance. Recently, a new type of checklist with dynamic properties has been created to provide more specific checklist items for each individual patient. The proof of concept of this dynamic clinical checklist (DCC; BJA 2017 (DOI: 10.1093/bja/aex129)) was tested in a simulation trial with improved outcomes and high acceptance scores. The purpose of this study is to investigate if the outcomes of th...
The overall purpose of the trial is to assess the clinical efficacy of three different subcutaneous doses of BI 655066 in adult patients with AS, in order to provide clinical proof of concept and to select dose (s) for confirmatory clinical trials.
Heart Transplant recipients at Tampa General Hospital heart transplant program who have pAMR1(H+) or pAMR1(I+) rejection will have a DD-cfDNA /GEP sample obtained at the time of the rejection. The DD-cfDNA/GEP will then be drawn every month post treatment for the rejection until the DD-cfDNA/GEP level returns to normal. A total of fifteen recipients with pAMR1(H+) and fifteen recipients with pAMR1(I+) rejection will be included in the study which will last two years. The presen...
Proof of concept study to validate the ability of the ingestible capsule to gather samples from the small bowel for microbiome analysis in adults.
This study will be a randomised, double blind, placebo controlled, 3-way, incomplete block crossover study to evaluate the effect of single and repeat doses of levocabastine, FF, placebo and a FDC of FF/levocabastine administration in AR subjects. The total expected study duration for each individual participating in the study will be a maximum of up to 20 weeks (including the screening and follow-up). This will be a three period study and subjects will be assigned to a sequenc...
This study is designed to determine the effects of dietary protein content on overfeeding.
The main objectives of the current study are to establish the safety and clinical proof-of-concept of NC-503 in inadequately controlled patients with Type 2 diabetes and features of metabolic syndrome treated with either metformin, a sulfonylurea agent, or metformin in combination with a sulfonylurea agent.
The primary purpose of this open-label, Phase 2 proof of concept study is to evaluate the efficacy of 12 months of oral ACH-0144471 in participants with C3G or IC-MPGN based on renal biopsy results and the number and percentage of participants with an improvement relative to baseline in clinical manifestation(s) of C3G (proteinuria and reduced estimated glomerular filtration rate [eGFR]).
This is the first study of AMT-130 in patients with early manifest HD and is designed to establish safety and proof-of-concept (PoC). CT-AMT-130-01 is a Phase I/II, randomized, multicenter, dose escalation, double-blind, imitation surgery, first-in-human (FIH) study.
Phase IV, proof-of-concept, randomized, open-label, multi-center, two-arm, 9-month study to evaluate the neuroprotective effects of Natalizumab (TYSABRIÂ®) or Interferon beta-1a (AVONEXÂ®) treatments initiated at the time of acute optic neuritis (AON) as measured by RNFL thickness from Optical Coherence Tomography in patients with Relapsing Remitting Multiple Sclerosis (RRMS).
MRI findings after successful PAE in patients suffering from BPH suggest a complete necrosis of the prostate after this intervention. Thus, PAE might also play a role in the treatment of prostate cancer. This proof of concept study assess the impact of PAE in patients with proven prostate cancer.
This study is a proof of concept study to confirm in a standardized manner the therapeutic efficacy of roflumilast in type 2 diabetes mellitus patients.
Donor-derived cell-free DNA (dd-cfDNA) has shown promise as an early marker for cellular injury caused by rejection. dd-cfDNA changes may also indicate other injuries that lead to progressive decline in transplant organ function associated with, in the case of kidney transplantation, the presence of interstitial fibrosis (IF) and tubular atrophy (TA) seen in biopsy specimens. Here, we will study the utility of dd-cfDNA to predict rejection in pancreas and pancreas-kidney recipi...
The purpose of this study is to validate the concept of adapted automated PD a modified Peritoneal Equilibration Test (PET), will be performed in children on chronic PD. Instead of a single 4 hour standard dwell, two double mini PET using the same type and total volume of dialysate and the same total dwell time (150min) will be performed in randomised sequence. An double mini test consists of two identical dwells, reflecting routine PD, the other one of a short small dwell foll...
Patients found pulmonary nodules by CT screening by will be enrolled in this study prospectively. Plasma cfDNA sequencing of these patients will be used to diagnose and monitor benign and malignant pulmonary nodules.
This is a randomised, placebo controlled, double blind, crossover proof of concept study to investigate the efficacy and safety of oral LAT8881 in acute migraine, with or without aura.
To compare the effectiveness of a 90-day Copaxone® adherence enhancement program for a sample of MS patients who are at high risk of nonadherence and receive support from Shared Solutions® and their MS Center versus those who receive support only from Shared Solutions®.
