PA-001 Ph.1 Study in Healthy and Elderly Subjects

NCT07518771 | Completed Phase 1 FDA Drug

• 1 other identifier: PA-001-101
• Study Type: interventional
• Target: 47
• Locations: 1 country
• Sites: 1

Brief Summary

This was a double blind, randomized, placebo controlled, single and multiple IV dose study conducted in 2 parts, single ascending dose and multiple ascending doses parts. The principal aim of this study was to obtain safety and tolerability data when PA-001 is administered IV as single and multiple doses to healthy subjects. This information, together with the PK data, will help establish the doses and dosing regimen suitable for future studies in patients. The study also investigated the effects of age on the PK of PA-001 prior to patient studies.

Outcome Measures

Primary Outcomes (3)

• Incidence and severity of adverse events after single and multiple IV dosed of PA-001 in healthy subjects

  An adverse event (AE) was any untoward medical occurrence in a subject, temporally associated with the use of study intervention. A serious adverse event (SAE) was defined as any untoward medical occurrence that, at any dose, met one or more of the following criteria: resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, resulted in a congenital anomaly/birth defect and resulted in an important medical events. TEAEs were defined as events that occurred after start of treatment.

  For approx. 8 weeks

• Incidence of laboratory abnormalities (hematology, clinical chemistry and urinalysis test)

  Clinical hematology parameters included: hemoglobin, hematocrit, red blood cell count, platelet count, white blood cell count, total neutrophils, eosinophils, monocytes, basophils, lymphocytes, mean cell hemoglobin (MCH), MCH concentration and mean cell volume. Chemistry parameters included: blood urea nitrogen, creatinine, estimated glomerular filtration rate, glucose, calcium, sodium, potassium, chloride, aspartate aminotransferase, alanine aminotransferase, total bilirubin, alkaline phosphatase, uric acid, albumin, total protein, bicarbonate, gamma-glutamyl transferase, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, B-type natriuretic peptide, highly sensitive troponin T and lactate dehydrogenase. Urinalysis parameters included: potential of hydrogen (pH), glucose, protein, blood, ketones, nitrite, leukocyte esterase, bilirubin, color and appearance, specific gravity.

  For approx. 8 weeks

• 12-lead electrocardiogram parameters

  A 12-lead ECG was performed. Clinically meaningful findings in ECG assessments were based on the investigator's judgment

  For approx. 8 weeks

Secondary Outcomes (5)

• AUCinf of PA-001 in plasma following single and multiple IV dose

  SAD: predose to 48 hours after start of infusion, MAD: predose to 48 hours after start of the last infusion

• AUClast of PA-001 in plasma following single and multiple IV dose

  SAD: predose to 48 hours after start of infusion, MAD: predose to 48 hours after start of the last infusion

• Cmax of PA-001 in plasma following a single and multiple IV dose

  SAD: predose to 48 hours after start of infusion, MAD: predose to 48 hours after start of the last infusion

• T1/2 of PA-001 in plasma following single and multiple IV dose

  SAD: predose to 48 hours after start of infusion, MAD: predose to 48 hours after start of the last infusion

• Percent Urinary Recovery of PA-001 following single IV dose

  SAD only, predose to 48 hours after start of infusion
