About this study

Official title: A Double-Blind, Randomized, Placebo- and Active Comparator- Controlled, Parallel Group, Multinational Study to Evaluate the PK and PD of IPX056 in Subjects With Established Spasticity Resulting From Multiple Sclerosis

The purpose of this study is to determine the effects, both good and bad, of IPX056 on subjects and their spasticity. This study will also determine the relationship between the amount of IPX056 in blood and the effects on spasticity. Lastly, this study will determine how long IPX056 affects spasticity.

Read the detailed description

The primary objective of this study is to demonstrate that IPX056 reduces spasticity, measured by Ashworth score, in subjects with multiple sclerosis (MS). This study will also (1) assess the correlation between pharmacokinetic (PK) and pharmacodynamic (PD) endpoints (Ashworth score), and (2) quantify the duration of pharmacodynamic effects for IPX056 as well as marketed baclofen tablet in subjects with Multiple Sclerosis (MS) after a single dose. Additionally, the efficacy parameters, including Multiple Sclerosis Impact Scale (MSIS)-29, spasm frequency and nighttime awakening score, spasticity control, morning stiffness, and Global Assessment of Efficacy and Tolerability, will be assessed during open-label extension period. The safety of IPX056 will be monitored throughout the study.

This study consists of 2 parts: Part I (Screening Visit \& Visit 1) of the study is a single-dose, double-blind, randomized, placebo- and active comparator-controlled, parallel group design containing a single 12 hour PK/PD evaluation period. Part II is an optional, approximately 9-week open-label extension study and will start during Visit 1, immediately after Visit 1 PK/PD procedures are completed.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Overall mean changes from predose (baseline) in total Ashworth scores of the four lower extremity muscle groups (hip adductors, knee flexors, knee extensors, and plantar flexors) of both lower limbs over 12 hours assessed hourly after dosing

    Measured: 12 hours

Secondary outcomes (2)
  1. Duration of effect (improvement in Ashworth Scale) for IPX056

    Measured: 12 hours

  2. Establishment of relationships between baclofen plasma concentration with improvement in Ashworth Scale

    Measured: 12 hours

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing IPX056 20 mg, IPX056 40 mg and Encapsulated Baclofen 20 mg in people with Multiple Sclerosis, run by Impax Laboratories, LLC at 31 sites in 5 countries.

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 10 inclusion and 23 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 6 Nov 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 31 sites in United States, Ukraine, Canada, Estonia, Latvia. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Overall mean changes from predose (baseline) in total Ashworth scores of the four lower extremity muscle groups (hip adductors, knee flexors, knee extensors, and plantar flexors) of both lower limbs over 12 hours assessed hourly after dosing (time frame: 12 hours). 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 Nov 2019.
