About this trial
The objective of this phase 1, open-label, single-center, two-way crossover trial is to evaluate the pharmacokinetics (PK), safety, and tolerability of 100 mg ASP-001 oral liquid suspension versus 100 mg Viagra (sildenafil citrate) tablets in fasted, healthy male volunteers
Eligibility criteria
This trial accepts healthy volunteersQualifiers
The participant must be informed of the nature of the study and voluntarily agree to participate by signing an informed consent form prior to any study-specific procedures.
Participants must be healthy male volunteers aged 18 to 55 years (inclusive) at the time of dosing.
Participants must have a body mass index between 18.0 and 29.9 kg/m² (inclusive) and a body weight of 50 to 100 kg (inclusive).
Participants must be judged by the Investigator or designee to be in good general health, as documented by medical history, physical examination, clinical laboratory tests, vital signs, and 12-lead electrocardiogram (ECG). Any deviations from normal ranges must be assessed and deemed not clinically significant by the Investigator or designee.
Disqualifiers
Unwillingness or inability to follow the procedures specified by the protocol.
Participant received any investigational drug/product within 30 days prior to the first dose.
History of significant renal, hepatic, cardiovascular (including orthostatic hypotension), psychiatric, neoplastic, inflammatory, infectious, diabetes mellitus, or other disease which, in the opinion of the Investigator, represents a safety risk for taking part in the study.
Presence of any clinically significant results from laboratory tests, vital signs assessments, and electrocardiograms, as judged by the Investigator and/or designee.

Trial outcomes
Primary outcomes
Cmax
The PK profile of ASP-001 and Viagra in healthy male subjects. Calculation of maximum plasma concentration (Cmax) over the specified timeframe.
Absorption
To determine if the rate and extent of absorption are similar for 100 mg of ASP-001 administered as 8 pumps of the 25 mg/mL oral liquid suspension of sildenafil compared to 100 mg Viagra (sildenafil) administered in the form of a film-coated tablet.
AUCt
The PK profile of ASP-001 and Viagra in healthy male subjects. Calculation of the area under the plasma concentration versus time curve will be calculated using the linear trapezoidal rule from the zero time point to the last quantifiable concentration (AUCt).
AUCi
The PK of ASP-001 and Viagra in healthy male subjects. The area under the plasma concentration versus time curve from zero to infinity (AUCi) will be calculated by adding the last quantifiable concentration (Ct)/ elimination rate contant (Kel) to AUCt.
Secondary outcomes
Number of participants with oral irritation, dizziness, or headache.
To determine the potential of ASP-001 to cause oral irritation, dizziness, or headache. Descriptive summaries (mean, standard deviation (SD), median, minimum, and maximum) of actual values and changes from baseline will be provided.
Number of participants with adverse events
The frequency and type of adverse events reported during the study.
