About this study

Official title: A Phase 2, Randomized, Double Blind, Placebo , Controlled Study To Evaluate The Administration of CN-105 In Participants With Acute Supratentorial Intracerebral Hemorrhage

Phase 2, randomized, double-blind, placebo controlled study to evaluate the administration of CN-105 in patients with supratentorial intracerebral hemorrhage (ICH). Patients will be evaluated for eligibility within 12 hours of symptom onset. Eligible participants (30 active participants and 30 control participants) will receive CN-105 or placebo administered intravenously (IV) for a 30-minute infusion every 6 hours for up to a maximum of 3 days (13 doses) or until discharge (if earlier than 3 days). Participants will be monitored daily throughout the Treatment phase of the study (up to a maximum of 5 days) and will receive standard-of-care treatment for the duration of the study. Additional protocol assessments will be required during the Treatment phase as outlined in Section 7.5. After discharge from the hospital, participants will enter a 3-month Follow-up phase, with a clinic visit at 30 days and a follow-up telephone interview with telephone-validated mRS at 90 days after first dose of study agent.

Phase 2, randomized, double-blind, placebo controlled study to evaluate the administration of CN-105 in patients with supratentorial intracerebral hemorrhage (ICH). Patients will be evaluated for eligibility within 12 hours of symptom onset. Eligible participants (30 active participants and 30 control participants) will receive CN-105 or placebo administered intravenously (IV) for a 30-minute infusion every 6 hours for up to a maximum of 3 days (13 doses) or until discharge (if earlier than 3 days). Participants will be monitored daily throughout the Treatment phase of the study (up to a maximum of 5 days) and will receive standard-of-care treatment for the duration of the study. Additional protocol assessments will be required during the Treatment phase as outlined in Section 7.5. After discharge from the hospital, participants will enter a 3-month Follow-up phase, with a clinic visit at 30 days and a follow-up telephone interview with telephone-validated mRS at 90 days after first dose of study agent.

The study is not powered to test any specific hypothesis in regard to safety and will instead use descriptive methods to describe the experience of the study cohort with respect to adverse and serious adverse events (SAEs), as well as the occurrence of several pre-specified events of interest. The secondary objective of this study will be met by comparing the modified Rankin score (mRS) at 30 days between participants treated with CN-105 with placebo controlled participants The mRS at 30 days will be compared between treated and control participants using the Wilcoxon rank sum test. Exploratory analyses include comparison of treated and control participants for radiographic cerebral edema and hematoma volume and expansion and biological markers of inflammation.

Primary: To assess safety of CN-105 administration in primary ICH.

Secondary: To evaluate whether the administration of CN-105 improves 30-day mortality and functional outcomes by comparing participants treated with CN-105 with placebo controlled participants.

Exploratory:

  • To investigate feasibility of Day 0, 1, 2, and 5 non-contrast head computed tomography (CT) as a radiographic surrogate to evaluate progression of perihematomal edema
  • To investigate feasibility of using serial biochemical markers of neuroinflammation and neuronal injury as a surrogate measure of perihematomal edema and clinical outcome in the setting of spontaneous ICH.Primary:
  • Number and severity of AEs throughout the duration of the study
  • Number and severity of SAEs throughout the duration of the study
  • In-hospital, 30-day, and 90-day mortality
  • Treatment-related mortality
  • In-hospital neurological deterioration, defined as an increase of National Institutes of Health Stroke Scale (NIHSS), > 2 from baseline and/or decrease of > 2 of Glasgow Coma Scale (GCS), persisting more than 24 hours, and unrelated to sedation
  • Incidence of cerebritis, meningitis, ventriculitis
  • Incidence of systemic infection
  • Incidence of hematoma extension Secondary:.
  • 30- and 90-day mRS
  • Need for intracranial hypertension management
  • NIHSS score, Glasgow Coma Scale, Montreal Cognitive Assessment, Stroke Impact Scale-16, and Barthel Index assessment at hospital discharge and 30 days after ICH
  • Discharge disposition

Exploratory:

  • Day 0, 1, 2, 5 non-contrast head CT as a radiographic surrogate to evaluate progression of perihematomal edema
  • Biochemical surrogates of brain injury, including plasma concentrations of S100B, glial fibrillary acidic protein, metalloproteinase-3 and -9, C-reactive protein, D-dimer, brain natriuretic peptide, interleukin-6, tumor necrosis factor-α, and vascular endothelial growth factor, assessed daily for 5 days after ICH or until discharge (concentration time area under the curve assessed for each biomarker)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Acetyl-Valine-Serine-Arginine-Arginine-Arginine-NH2 (Ac-VSRRR- NH2). and 0.9% Sodium-chloride in people with Intracerebral Hemorrhage, run by National Neuroscience Institute at 1 site in Singapore.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Dec 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Singapore. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

adverse event (time frame: 0-12 hours). The study lists 55 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03711903, which also lists 17 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Dec 2022.
