Trial Outcomes & Findings for AMP as a Better Delivery System of Adenosine (NCT NCT00179010)

NCT ID: NCT00179010

Last Updated: 2019-05-07

Results Overview

Recruitment status

TERMINATED

Study phase

PHASE1

Target enrollment

13 participants

Primary outcome timeframe

Microdyalysis samples for adenosine, were collected for 15 minutes at each stage of the study (baseline and each dose of adenosine or AMP)

Results posted on

2019-05-07

Participant Flow

Subjects were recruited through mass e-mails and flyers posted in campus

Subjects were randomly assigned to each treatment arm, after being screened for any medical problem that would be considered a contraindication for the study according to the physician performing the initial evaluation. Once subjects completed one arm, they were crossed to the other arm and studied at lest one month after.

Measure
Adenosine First Then AMP
Intrarterial infusion of adenosine first Adenosine: Adenosine intrarterial (intrabrachial) infusion at 3 diferent doses for 15 minutes each Subjects in this group were assigned to received intrarterial infusions of adenosine and then crossed to the other arm (AMP) after at least 1 month.
Adenosine Mono Phosphate (AMP) First Then Adenosine
Intrarterial infusion of AMP first Adenosine Mono Phosphate (AMP): Intraterial infusion of AMP at 3 different doses for 15 minutes each (at equimolar doses as adenosine) Subjects intros group were assigned to received intrarterial infusions of AMP and then crossed to the other arm (adenosine), at least 1 month after.

PRIMARY outcome

Timeframe: Microdyalysis samples for adenosine, were collected for 15 minutes at each stage of the study (baseline and each dose of adenosine or AMP)

Population: 13 subjects received both treatments. 3 subject did not complete the study and were excluded. We are reporting data in only 10 subjects that have collected samples.
