Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Key inclusion criteria:

  • Signed informed consent prior to any study-mandated procedure.
  • Male and female subjects aged 18 years and above with a history of recurrent multiple weekly RP attacks secondary to SSc.
  • Women of childbearing potential must agree to use a reliable method of birth control.

Key exclusion criteria:

  • Known moderate or severe hepatic impairment (i.e. Child-Pugh C).
  • Known hypersensitivity to selexipag or drugs of the same class, or any of their excipients.
  • Subjects who have received prostacyclin (epoprostenol) or prostacyclin analogs (i.e., treprostenol, iloprost, beraprost) within 3 months prior to the screening visit.
  • Subjects who have received a Phosphodiesterase type 5 (PDE-5) inhibitor within 1 week prior to the screening visit.
  • Any dose change or initiation of any of the following drugs within 1 month prior to the screening visit: Calcium channel blockers, Nitrates or nitric oxide donors, ERA's, Alpha-blockers, Antithrombotic agents, NSAIDs (occasional use allowed), Angiotensin Converting Enzyme (ACE) inhibitors, Beta-blockers, Clonidine, Systemic corticosteroids, Fluoxetine.
  • Severe renal insufficiency (at randomization).
  • Any circumstances or conditions, which, in the opinion of the investigator, may affect the subject's full participation in the study or compliance with the protocol

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Selexipag
Selexipag is initiated at 200 µg twice daily (b.i.d.) and up-titrated every 3 days in 200 μg b.i.d. increments up to the maximum tolerated dose (MTD) for each individual patient but not above 1600 µg during the 3-week titration phase. This is followed by a 5-week maintenance phase, during which patients continue the treatment at their individual MTD.
Drug: Selexipag
Film-coated tablets containing 200 μg of selexipag to be administered orally twice daily
Other Names:
  • ACT-293987
Experimental: Placebo
Placebo matching selexipag tablets is administered according to the same schedule as selexipag
Drug: Placebo
Placebo matching selexipag 200 μg tablets to be administered orally twice daily

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Average number of Raynaud's phenomenon (RP) attacks per week during the maintenance treatment period
Time Frame: From Day 26 to Day 56 ( +/- 7 days)
The number of RP attacks is determined from daily entries in electronic Diaries (eDiary).
From Day 26 to Day 56 ( +/- 7 days)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of patients with treatment-emergent adverse events
Time Frame: Up to end of study (Day 86 +/- 7 days)
A treatment-emergent adverse event is any adverse event (AE) temporally associated with the use of a study treatment, whether or not considered related to the study treatment, including any abnormalities in ECG parameters, vital signs or laboratory tests
Up to end of study (Day 86 +/- 7 days)
Number of patients with treatment-emergent serious adverse events
Time Frame: Up to end of study (Day 86 +/- 7 days)
Up to end of study (Day 86 +/- 7 days)

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change from baseline in quality of life (QOL)
Time Frame: At baseline (Day 1) and end of treatment (Day 56 +/- 7 days)
QOL is assessed by the Scleroderma Health Assessment Questionnaire (SHAQ)
At baseline (Day 1) and end of treatment (Day 56 +/- 7 days)

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
