NCT ID: NCT05630807 Active, not recruiting - Chronic Hepatitis B Clinical Trials

Study of Bepirovirsen in Nucleos(t)Ide Analogue-treated Participants With Chronic Hepatitis B (B-Well 1)

B-Well 1
Start date: December 7, 2022
Phase: Phase 3
Study type: Interventional

This study is intended to confirm the efficacy, safety, pharmacokinetic (PK) profile, and the durability of hepatitis B virus surface antigen (HBsAg) suppression observed with bepirovirsen for 24 weeks (with loading doses) as compared to the placebo arm. This study will have 4 stages: a) Double-blind treatment (bepirovirsen or placebo) for 24 weeks. b) Nucleos(t)ide analogue (NA) treatment for 24 weeks. c) NA cessation stage OR Continue NA for 24 weeks. d) Durability of response and follow up for further 24 weeks for participants who stopped NA treatment at Week 48. The arms will be stratified based on HBsAg level (HBsAg greater than or equal to [≥] 100 international unit per milliliter [IU/mL] to less than or equal [≤]1000 IU/mL or greater than [>] 1000 IU/mL to ≤3000 IU/mL) at screening. The total duration of the study, including screening (up to 60 days), the double-blind treatment stage (24 weeks), the On NA only stage (24 weeks), and the NA cessation and durability stages (48 weeks) is up to approximately 104 weeks at maximum for each participant.

NCT ID: NCT05595538 Completed - COVID-19 Clinical Trials

Use of Multiple Doses of Convalescent Plasma in Mechanically Intubated Patients With COVID-19

Start date: June 6, 2020
Phase: Early Phase 1
Study type: Interventional

This study will assess the feasibility and safety of administering multiple doses of convalescent plasma to Covid-19 positive patients admitted to the Intensive Care Unit (ICU) receiving mechanical ventilation. Donor plasma will be obtained from Covid-19 recovered patients. All plasma used in this protocol will be collected following the guidelines issued by the Food and Drug Administration (FDA) and the Ministry of Health in Panama. Every patient recruited will receive one or two plasma units infused on days 0, 2, 4, 6, and 8. The primary objective of this study is feasibility. Feasibility will be assessed based on the proportion of subjects who consent and receive at least one dose of convalescent plasma more than once. The investigators will evaluate the safety and feasibility of this study by accounting for any related adverse event. The secondary study endpoints are overall survival at days 14, 28, and 60 after the first dose of convalescent plasma. Respiratory status and overall clinical status will be reviewed during follow-up until day nine and on days 14, 28, and 60.

NCT ID: NCT05594056 Completed - Preeclampsia Severe Clinical Trials

Transorbital Ultrasound of Optic Nerve Sheath Diameter Between Healthy Pregnant Women and Those With Severe Preeclampsia.

Start date: October 21, 2022
Phase: N/A
Study type: Interventional

The neurological alterations associated with preeclampsia depend on cerebral autoregulation, a theory that outlines the mechanisms by which the nervous system controls cerebral perfusion. However, with the loss of autoregulation, increased blood flow, edema and eventually increased intracranial pressure are triggered and may be translated into neurological manifestations such as symptoms of vasospasm, one of the criteria for severity in preeclampsia. Nervous system manifestations frequently found in preeclampsia are headache, blurred vision, scotomas and hyperreflexia. Although uncommon, temporary blindness (lasting a few hours to a week) may also accompany severe preeclampsia and eclampsia. The optic nerve, as part of the central nervous system, is surrounded by cerebrospinal fluid and dura mater, which forms the optic nerve sheath. Due to the connection with the intracranial subarachnoid space, the diameter of the optic nerve sheath is influenced by variations in cerebrospinal fluid pressure. Increased intracranial pressure is transmitted to the subarachnoid space surrounding the optic nerve, causing its expansion. Recent studies suggest that an optic nerve sheath diameter greater than 5 mm correlates 100% with ICP (intracerebral pressure) greater than 20 mm Hg. Due to the simple nature of the test and the limited time required to perform it, it is an ideal non-invasive test to assess changes in mental status, severe headache, and to take the necessary measures aimed at reducing intracranial pressure. The diagnosis of elevated intracranial pressure is challenging and critical, because early recognition and treatment are essential to prevent brain damage or death since preeclampsia with severe data remains one of the most frequent complications in our institution. These values are not taken from the obstetric population, so this study proposes the description of a standard value for the pregnant population. There are few studies that describe a value to help us define cases of this pathology and correlate it with the signs and symptoms of severity in patients with preeclampsia.
