NCT ID: NCT04396106 Terminated - COVID-19 Clinical Trials

Safety and Efficacy of AT-527 in Subjects With Moderate Coronavirus Disease (COVID-19) in a Hospital Setting

Start date: May 26, 2020
Phase: Phase 2
Study type: Interventional

The objectives of this study are to evaluate the safety, tolerability, antiviral activity and efficacy of AT-527 in adult subjects ≥18 years of age with moderate COVID-19 and risk factors for poor outcomes (such as obesity (BMI>30), hypertension, diabetes or asthma). Eligible subjects will be randomized to blinded AT-527 (nucleotide analog) tablets or matching placebo tablets to be administered orally for 5 days. Part A will evaluate an AT-527 dose of 550 mg BID and Part B will evaluate a second dose of AT-527 (1100 mg BID). Local supportive standard of care (SOC) will be allowed for all subjects. Efficacy, antiviral activity and safety observations will be compared for treatment with active AT-527 tablets vs. placebo tablets.

NCT ID: NCT04220281 Terminated - Clinical trials for Hypotensive Anesthesia

Comparison Between Two Drugs (Propofol and Nitroglycerin as a Hypotensive Agents During Endoscopic Sinus Surgery

prop
Start date: December 1, 2019
Phase: Phase 1/Phase 2
Study type: Interventional

Background and Objectives: FESS is a common minimally invasive surgery that requires a clear field to be performed well. Hypotensive anesthesia is one of the most common maneuvers performed to help in keeping the field clear. An ideal drug for hypotensive anesthesia should be cheap and familial to the anesthesiologist. So being familial with propofol and by using its cardio-depressant action the idea of the research was developed and comparing it with nitroglycerin (a hypotensive agent in our protocol). Methods: The patients agreed to participate in the research were classified into two groups for comparison. Propofol group; received propofol infusion all over the procedure, and nitroglycerin group; received nitroglycerin infusion all over the procedure. Duration of surgery, visibility of surgical field and amount of blood loss were recorded. Pulse/min and MAP were recorded at baseline and every 5 min. Results: The mean duration of surgery was longer in the NTG to propofol group. There was high statistical significance in the average blood loss in the propofol group compared to NTG group. The visibility of the operative field also was significant in the propofol group as compared to NTG group. The mean heart rate in the NTG group is higher than the mean heart rate in the propofol group. The MAP in both groups is within a close range. Conclusion: Propofol and NTG can produce a safe and effective controlled hypotension during FESS. Whereas, propofol has; a better surgical field visibility, less surgical bleeding and less tachycardia during FESS.

NCT ID: NCT04210414 Terminated - Infertility Clinical Trials

Cleave-stage Transfer on Day 3 Versus Day 5 Transfer When Only One Embryo Available

Cleave-blast
Start date: January 10, 2020
Phase: N/A
Study type: Interventional

When only one embryo is available after in vitro fertilization, the option is to transfer either day 3 or day 5. There is no randomized trial compared the day 3 to day 5 for this subgroup.

NCT ID: NCT04124809 Terminated - Clinical trials for Blastocyst Disintegration

Truth or Dare; Artificial Blastocoel Collapse Using Laser Before Blastocyst's Vitrification Versus Non-laser Usage

Start date: January 5, 2019
Phase: N/A
Study type: Interventional

: This prospective randomized observational study aimed to compare behavior of artificially collapsed blastocysts to blastocysts that were vitrified without artificial collapse.

NCT ID: NCT04052607 Terminated - Infertility Clinical Trials

Progestin Priming Ovarian Stimulation (PPOS) Compared With Antagonist Protocol for Freeze-all Cycles

ANTA-PPOS
Start date: September 10, 2019
Phase: N/A
Study type: Interventional

Stimulation protocols for IVF underwent several cycles of upgrading aiming to achieve reasonable outcomes with low-cost cycles. Antagonist protocols have been introduced as effective and comparable to long agonist regarding the outcomes. However, these protocols are still costly. Alternative protocols using progestin suppressions appear options for consideration.

NCT ID: NCT03787901 Terminated - Infertility Clinical Trials

Comparing the Ongoing Pregnancy Rate for Vitrification of Day-4 Morula With Day-5 Blast

Start date: January 15, 2019
Phase: N/A
Study type: Interventional

Comparing the vitrification at Day-4 (morula stage) with the blastocyst stage vitrification outcomes with the transfer of all day 5 after warming seems need evaluation. To the best of our knowledge, there has been no random-controlled trial conducted such comparison. Altogether, this trial is to evaluate the morula stage vitrification to blastocyst vitrification on the ongoing pregnancy rate after ICSI.

NCT ID: NCT03786302 Terminated - Pulpotomy Clinical Trials

Regenerative Ability of TAMP BG and BD in Pulpotomized Primary Teeth

Start date: December 6, 2016
Phase: Phase 2
Study type: Interventional

The aim of this study was to assess clinically, radiographically, and histologically the regenerative ability of Tailored Amorphous Mulioporous (TAMP-BG) bioglass in comparison to Biodentine™ (BD) in pulpotomized primary teeth.

NCT ID: NCT03774784 Terminated - Amyloidosis Clinical Trials

A Study of the Natural History of Leukocyte Chemotactic Factor 2 Amyloidosis (ALECT2) Disease

Start date: January 29, 2019
Phase:
Study type: Observational

The purpose of this study is to characterize the natural history of leukocyte chemotactic factor 2 amyloidotic (ALECT2) disease. In this observational study participants with ALECT2 disease will be enrolled. Participants, who have already reached end-stage renal disease (ESRD), will provide retrospective chart review data and biological specimens at baseline only. Other participants, in addition to retrospective chart review, will be followed prospectively.

NCT ID: NCT03668106 Terminated - Clinical trials for Sperm DNA Fragmentation

Effect of Different Sperm Processing Methods in ICSI Outcome.

Start date: May 1, 2018
Phase: Phase 2/Phase 3
Study type: Interventional

A total 180 semen samples from couples diagnosed with unexplained infertility were SDF index tested , then total 120 semen samples of patients' husbands with abnormal SDF index were randomly divided and then processed by swim up, sperm gradient centrifugation and Zeta methods. SDF and ICSI outcomes are monitored after semen processing.
