About this study

Official title: A Phase I Study to Assess the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Single Oral Doses of SP-8008 in Healthy Male Subjects

This is a single-centre, double-blind, randomised, placebo-controlled single oral-dose escalation study in healthy male subjects. It is planned to enrol approximately 48 subjects into up to 6 planned dose level cohorts.

Subjects will be randomly assigned to receive a single oral dose of active Investigational medicinal product (IMP) or matching placebo in a sequential escalating manner with at least 14 days planned between dose cohorts. Dose review of the preceding dose will take place during the 14 day interval.

The study will consist of escalating single doses in sequential cohorts. Each dose level cohort will consist of 8 subjects; 6 subjects will receive SP-8008 and 2 subjects will receive placebo according to the randomisation schedule. For all dose levels the first 2 sentinel subjects will be randomised 1:1 to placebo or SP-8008, and the remaining 6 subjects will be randomised 1:5 to placebo or SP-8008, respectively.

Read the detailed description

Investigational medicinal product (IMP) will be administered at only 1 dose level at a time. Following each of Periods 1, 2, 3, 4, and 5, there will be a period of interim analysis and review of safety, PK and available PD data from the previous period(s) in order to determine which SP 8008 formulation and dose to administer further regimens. Administration at the next dose level will not begin until the safety and tolerability of the preceding dose level have been evaluated and deemed acceptable by the investigator and sponsor, and the exposure of SP-8008 remains within the pre specified limits following interim review. There will be an interval of no less than 14 days between the dosing of successive cohorts, unless a subject cohort returns to a dose that is lower than that already given in a previous cohort eg to obtain dose linearity information. Dose escalation will be guided by emerging safety, PK and available PD data and confirmed after each interim data review meeting.

There is the option to assess the safety, PK and PD of an alternative formulation. This formulation will be invoked if, following review of data from the preceding periods, it is decided that the exposure from the current formulation may not be ideal for future development.

    Measured: Follows up to 48 hours

  2. To evaluate the effect of single dose SP-8008 on platelet function through inhibition of platelet aggregation (IPA)

    Evaluate the PD effects of SP-8008 to investigate the increment of platelet aggravating physiological factors under IPA conditions. The effect of SP-8008 on IPA will be evaluated in anti-coagulated blood with citrate using the Platelet Function Analyser (PFA-100) instrument and optical aggregometry.

    Measured: Follows up to 48 hours

  3. To characterize the pharmacokinetics of SP-8008 in health male subjects. - Peak Plasma Concentration (Cmax)

    Evaluate Maximum Observed Drug Concentration (Cmax) of SP-8008.

    Measured: Follows up to 48 hours

  4. To characterize the pharmacokinetics of SP-8008 in health male subjects. - Area under the plasma concentration versus time curve from time zero to infinity (AUC[0-∞])

    Evaluate Area Under the Concentration Versus Time Curve from Time Zero to Infinity (AUC[0-∞]) of SP-8008.

Model description
Subjects will be screened for inclusion in the study up to 28 days prior to dosing. Subjects will be admitted to the clinical unit on the morning of Day -1, and will be dosed in a randomised, double-blind manner on the morning of Day 1 following an overnight fast (approximately 10 h). Drug administration will be performed with an appropriate interval (approximately 10 min) between subjects based on logistical requirements. Subjects will remain resident in the clinical unit until up to 48 h after dosing (up to Day 3). Subjects with AEs that represent a cause for concern will be asked to remain resident in the clinical unit until the AE resolves or stabilises. The minimum interval between dose administrations will be 14 days to allow for interim review of PK and safety data from the previous regimen. A follow-up visit will take place 5 to 7 days post-dose for assessment of safety and tolerability.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing SP-8008 Prototype Capsule A and SP-8008 Prototype Capsule B in people with Acute Coronary Syndrome and Stroke, run by Shin Poong Pharmaceutical Co. Ltd. at 1 site in United Kingdom.

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 7 inclusion and 20 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 25 Feb 2021. 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 United Kingdom. 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?

Safety profile of single doses of SP-8008 in healthy male subjects was evaluated with serious adverse drug reactions (SADRs) (time frame: Follows up to 7 days). The study lists 3 primary outcomes in all. 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 25 Feb 2021.
