A Study to Learn About the Treatment LTP001 in Healthy Participants (Part A) and in Participants With PAH (Part B)

A Randomized, Double-blind, Placebo-controlled Study to Evaluate the Safety, Tolerability and Pharmacokinetics of Single and Multiple Ascending Doses of LTP001 in Healthy Adult Participants (Part A) and to Evaluate the Efficacy and Safety of LTP001 for the Treatment of Participants With Pulmonary Arterial Hypertension (Part B)

Brief summary

A study to learn about the treatment LTP001 in healthy participants (Part A) and in participants with PAH (Part B)

Detailed description

The CLTP001A12202 study will explore the safety, tolerability, and pharmacokinetics of LTP001 in healthy volunteers (Part A) and will evaluate the safety and efficacy (Part B) followed by safety extension in participants with pulmonary arterial hypertension.

Design outcomes

Primary

MeasureTime frameDescription
Part A- Number of participants with Adverse events (AEs) and Serious Adverse events (SAEs)Baseline to Day 35Safety endpoints, including vital signs, ECG, clinical laboratory evaluations and adverse events up to and including the end-of-study visit.
Part B-Treatment Period 1: Change in pulmonary vascular resistance (PVR)Baseline to Week 24PVR is a hemodynamic variable of pulmonary circulation and is measured by right heart catheterization.
Part B-Treatment Period 2: Number of participants with Adverse events (AEs) and Serious Adverse events (SAEs)From Day 1 until Week 106Safety endpoints, including vital signs, ECG, clinical laboratory evaluations, treatment-emergent adverse events and discontinuations due to adverse events.

Secondary

MeasureTime frameDescription
Part A- Maximum observed plasma concentrations (Cmax)Baseline to Day 35Cmax is defined as the maximum (peak) observed concentration following a dose.
Part A- Time to reach maximum plasma concentration (Tmax)Baseline to Day 35Tmax is defined as the time to reach maximum (peak) concentration following a dose.
Part A- Area under plasma concentration-time curve from time zero to the last measurable concentration sampling time (AUClast)Baseline to Day 35AUClast is the area under the plasma concentration-time curve from time zero to the time of last quantifiable concentration (tlast).
Part A- Area under the plasma concentration-time curve from time zero extrapolated to infinity (AUC[0-inf])Baseline to Day 35The AUC is the area under the plasma concentration from time zero to infinity (mass x time x volume-1).
Part A- Terminal elimination half-life (T1/2)Baseline to Day 35T1/2 is the elimination half-life associated with the terminal slope.
Part B-Treatment Period 1: Change in the Six-minute Walk Test (6MWT)Baseline to Week 24The 6MWD test is self-paced, with standardized instructions and encouragement being given as participants walk as far as possible over 6 minutes through a flat corridor.
Part B-Treatment Period 1: Change in N-terminal pro-brain natriuretic peptide (NT-proBNP)Baseline to Week 24N-terminal pro brain natriuretic peptide (NTproBNP) are peptide (small proteins) that are either hormones or part of the peptide that contained the hormone at one time. They are continually produced in small quantities in the heart and released in larger quantities when the heart senses that it needs to work harder, as in heart failure.
Part B-Treatment Period 1: Change in World Health Organization (WHO) functional class (FC)Baseline to Week 24The Investigator or study staff will assign a WHO functional class to a participant based on reports of symptoms and activity limitation. * Class I: symptom-free when physically active or resting. * Class II: no symptoms at rest, but normal activities such as climbing the stairs, grocery shopping, or making the bed cause some discomfort and shortness of breath. * Class III: resting may be symptom-free, but normal chores around the house are greatly limited due to shortness of breath and feeling tired. * Class IV: symptoms at rest and severe symptoms with an activity
Part B-Treatment Period 2: Change in the Six-minute Walk Test (6MWT)Baseline to Month 18The 6MWD test is self-paced, with standardized instructions and encouragement being given as participants walk as far as possible over 6 minutes through a flat corridor.
Part B-Treatment Period 2: Change in World Health Organization (WHO) functional class (FC)Baseline to Month 18The Investigator or study staff will assign a WHO functional class to a participant based on reports of symptoms and activity limitation. * Class I: symptom-free when physically active or resting. * Class II: no symptoms at rest, but normal activities such as climbing the stairs, grocery shopping, or making the bed cause some discomfort and shortness of breath. * Class III: resting may be symptom-free, but normal chores around the house are greatly limited due to shortness of breath and feeling tired. * Class IV: symptoms at rest and severe symptoms with an activity
