About this study
Official title: A Single Center, Randomised Study to Investigate Pharmacokinetics of CS1, Safety and Tolerability and in Obese, Borderline Hypertensive But Otherwise Healthy and Medicine Free Subjects After Administration of Single and Multiple Doses
SAD study:
Eighteen subjects will be included in the SAD study (single dose) in 3 parallel arms, each with 6 subjects. The 3 arms will receive a single dose of one of the CS1 formulations I, II or III. The result of the pharmacokinetics analysis from the 6 first subjects is defined as SAD Pilot and will be used to evaluate the timing of PK sampling. Based on pharmacokinetic evaluations from all 18 subjects one of the formulations I (275 mg), II (276 mg) or III (276 mg) will be chosen to proceed into the MAD study. If none of the formulations show the desired PK properties the formulations may be re-dosed with a slightly different timing of the dose, i.e the IMP to be administered earlier or later during the evening.

MAD study:
Fifteen subjects will be included in a dose escalating study with 2 dose levels. The subjects will receive the lowest dose level (275 or 276 mg depending on the outcome of SAD) for the first 2 weeks before the dose is doubled (550 or 552 mg depending on the outcome of SAD) for the following 2 weeks.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing CS1-Sodium Valproate in people with Thrombosis, run by Cereno Scientific AB at 1 site in Sweden.
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 14 inclusion and 28 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 8 Apr 2019. 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 Sweden. 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
Pharmacokinetic of CS1 in plasma (time frame: up to four weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 8 Apr 2019; AzTrials last refreshed its copy on 7 Nov 2026.
