About this study

Official title: Phase 1, Randomized, Double-Blind, Active and Placebo Controlled, Dose Escalation Study to Evaluate the Safety, Pharmacokinetics and Pharmacodynamics of EXPAREL® Administered Via a Single Intrathecal Injection to Healthy Volunteers.

Primary objective: To assess the safety and tolerability of EXPAREL® administered as a single intrathecal injection in healthy volunteers

Secondary objective: To characterize the pharmacokinetic (PK) and pharmacodynamic (PD) profile of EXPAREL® administered as a single intrathecal injection in healthy volunteers

Read the detailed description

This is a Phase-1, single center, randomized, double-blind, active and placebo-controlled study in approximately 40 healthy adult subjects.

On Day 1, eligible subjects will be randomized in blocks of 5, in a ratio of 3:1:1 to receive EXPAREL® or bupivacaine or placebo (saline) injection, respectively. Starting with treatment Cohort 1, healthy volunteers will be randomized to the 3 treatment arms within cohorts. Each cohort will consist of 10 subjects (6 EXPAREL®, 2 bupivacaine and 2 placebo). In each cohort, all 10 subjects in each cohort will receive cerebrospinal fluid (CSF) taps. Within the EXPAREL® arm, subjects will be randomized 2:1 with 4 subjects undergoing CSF tap and 2 subjects not undergoing CSF tap in each cohort. Subjects who are not undergoing CSF tap, will still be injected with needles without draw of CSF to prevent subject bias. Such a randomization will allow for characterization of the complete pharmacodynamics profile of the drug without risk of drug removal in the CSF. For those subjects randomized to the EXPAREL® arm - the dose of EXPAREL® will be determined by the cohort. Starting at 1 mL (13.3 mg) for Cohort 1, the volume of EXPAREL® will be increased by 1 mL in each subsequent cohort for a maximum of 4 mL (53.2 mg). The decision to proceed to the next cohort will be made following a full review of the safety, PK, and PD (sensory and motor) data from current completed cohort(s). All subjects will remain in the EPRU for 5 days after drug administration and will be discharged on Day 6. Subjects will be instructed to return for a follow up visit on Day 9. Adverse events (AEs) and serious adverse events (SAEs) will be recorded from the time of consent through 30 days after drug administration.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing EXPAREL and Bupivacaine Hydrochloride in people with Healthy, run by Pacira Pharmaceuticals, Inc at 1 site in United States.

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 3 inclusion and 11 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: stopped early, as of the sponsor's last update on 6 May 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 States. 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 was stopped early (reason given: Terminated for strategic and administrative reasons). Results are not available in the source record.

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?

Area under the plasma concentration-versus-time curve (time frame: 6-8 weeks). The study lists 5 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 6 May 2021.
