NCT ID: NCT04749121 Completed - Covid19 Clinical Trials

Ultraviolet Germicidal Irradiation on the New Silicone Half-Piece Elastometric Respirators

Start date: April 1, 2020
Phase: N/A
Study type: Interventional

Since the innovation of our new half- elastometric half-piece respirator, this type of FFR has been used widely in our country. Decontamination methods including ultraviolet C (UVC) germicidal irradiation and 70% alcohol have been implemented to decontaminate the respirator. We than examined inactivation potential for the Porcine epidemic diarrhea virus (PEDV), numerous bacterial strains ,mostly skin-derived after the decontamination process.To enable rigorous integrity after repeated decontamination process, fit test by the Bitrex test ,tensile strength and elongation at break were also evaluated. Our results showed that the UVC at the dose of 3 J/cm2 can eradicate the bacteria at 60 min and virus at 10 min.No fungus was found on the mask surface at the beginning. Good Fit test , tensile strength and elongation at break were still main maintained after multiple cycles of decontamination. No evidence of physical degradation by gross visual inspection was found. 70% alcohol is also an easy and effective way to eradicate microorganisms on the mask.As the current pandemic is expected to continue for months to years, the need to supply adequate reserves of PPE and develop effective reprocessing is crucial. Our studies demonstrated that the novel silicone mask can be safely reprocessed and decontaminated for many cycles by UVC irradiation and help restore the shortage of the important protective devices in the COVID-19 pandemic era.

NCT ID: NCT04743375 Recruiting - Wound Heal Clinical Trials

To examine the efficacy and safety of sericin dressing with collagen in STSG donor site treatment comparing with Bactigras®. Around 30 patients will be enrolled in this study.

NCT ID: NCT04742192 Completed - Clinical trials for Non-small Cell Lung Cancer

Non-interventional, Prospective Study to Determine Prevalence of EGFR Mutations in Non-small Cell Lung Cancer

EARLY-EGFR
Start date: March 4, 2021
Phase:
Study type: Observational

This prospective, multicountry, multicentre, non-interventional study plans to include patients who have undergone surgery for early-stage (IA to IIIB on the basis of pathologic criteria) non-squamous NSCLC up to 6 weeks prior to enrolment into the study. The main objective of this study is to determine the prevalence of EGFRm in patients with surgically resected early-stage (IA to IIIB) non-squamous NSCLC as there are limited data on its prevalence in this patient population.

NCT ID: NCT04738487 Recruiting - Lung Neoplasms Clinical Trials

Coformulation of Pembrolizumab/Vibostolimab (MK-7684A) Versus Pembrolizumab (MK-3475) Monotherapy for Programmed Cell Death 1 Ligand 1 (PD-L1) Positive Metastatic Non-Small Cell Lung Cancer (MK-7684A-003, KEYVIBE-003)

Start date: April 7, 2021
Phase: Phase 3
Study type: Interventional

The primary hypotheses are that coformulated pembrolizumab/vibostolimab is superior to pembrolizumab alone with respect to (1) overall survival (OS) in participants with programmed cell death 1 ligand 1 (PD-L1) tumor proportion score (TPS) ≥50%, TPS ≥1% and TPS 1% to 49%; and (2) progression-free survival (PFS) per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 by blinded independent central review (BICR), in participants with PD-L1 TPS ≥1% and TPS ≥50%.

NCT ID: NCT04736706 Active, not recruiting - Clinical trials for Carcinoma, Renal Cell

A Study of Pembrolizumab (MK-3475) in Combination With Belzutifan (MK-6482) and Lenvatinib (MK-7902), or Pembrolizumab/Quavonlimab (MK-1308A) in Combination With Lenvatinib, Versus Pembrolizumab and Lenvatinib, for Treatment of Advanced Clear Cell Renal Cell Carcinoma (MK-6482-012)

Start date: April 14, 2021
Phase: Phase 3
Study type: Interventional

The goal of this study is to evaluate the efficacy and safety of pembrolizumab plus belzutifan plus lenvatinib or pembrolizumab/quavonlimab plus lenvatinib versus pembrolizumab plus lenvatinib as first-line treatment in participants with advanced clear cell renal cell carcinoma (ccRCC). The primary hypotheses are (1) pembrolizumab plus belzutifan plus lenvatinib is superior to pembrolizumab plus lenvatinib with respect to progression-free survival (PFS) and overall survival (OS), in advanced ccRCC participants; and (2) pembrolizumab/quavonlimab plus lenvatinib is superior to pembrolizumab plus lenvatinib with respect to PFS and OS, in advanced ccRCC participants.

NCT ID: NCT04731415 Not yet recruiting - Retinal Vascular Clinical Trials

Physiologic Change of Posterior Ocular Segment During Pregnancy

Start date: July 1, 2021
Phase: N/A
Study type: Interventional

Women's physiology changes markedly during normal pregnancy. The most distinct alterations occur in the hormonal and cardiovascular systems. There is a dramatic increase in both estrogen and progesterone. Blood volume starts to increase in the first gestational period and reaches a peak in the third trimester. The physiologic ocular changes during pregnancy are mainly the result of hormonal and blood volume increase, and then are usually marked in the third trimester.
