Intervention / Treatment

Intervention / Treatment

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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 to 45 years (Adult)

Accepts Healthy Volunteers

Yes

  • Previous treatment with acetylsalicylate, non-steroidal anti-inflammatory drugs or any medication with blood thinning activity within 3 weeks prior to study drug administration; or with any other prescribed medications (including vaccines) or over the counter medications within 2 weeks prior to study drug administration
  • Any circumstances or conditions, which, in the opinion of the investigator, may affect 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: AC-076 sc administration - single ascending dose
On Day 1, 48 subjects will receive AC-076 at different single dose levels in a sequential manner and in a maximum of 6 dose levels, starting from 1 mg. Subjects will be followed by an observation period of 48 h. Each dose level will be investigated in a new group of 8 healthy male subjects (6 on active drug and 2 on placebo)
Drug: AC-076 for s.c. administration
Lyophilized AC-076A to be reconstituted with 1 mL of water for injection
Placebo Comparator: Placebo
For each AC-076 dose level tested, 2 healthy male subjects will receive matching placebo in the same condition
Drug: Placebo
Sterile 0.9% w/v sodium chloride solution

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.
