Extension Study for Participants in LIQ861 Trials to Evaluate the Long-term Safety of Dry Powder Inhalation of Treprostinil

January 28, 2025 updated by: Liquidia Technologies, Inc.

A Global, Open-Label Extension Study for Participants in LIQ861 Trials to Evaluate the Long-term Safety of Inhaled LIQ861 (Treprostinil) in Pulmonary Arterial Hypertension (WHO Group 1) Patients

The primary objective of this study is to evaluate the long-term safety of LIQ861 in patients with pulmonary arterial hypertension (PAH).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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.

Detailed Description

One of the greatest impediments to patient treatment satisfaction with current inhaled treprostinil therapy is inconvenience. Currently, PAH patients using inhaled treprostinil may require more than 36 breaths per day using a nebulizer requiring daily set up and cleaning. The use of a discrete, hand-held dry powder inhaler to deliver treprostinil to the lungs could represent a major improvement in convenience and patient satisfaction, thereby improving the quality of life for PAH patients. Liquidia is pursuing approval of LIQ861, an inhalation dry powder formulation of treprostinil that is produced using Liquidia's PRINT® Technology (Particle Replication in Nonwetting Templates), as an alternative to current inhaled treprostinil therapy for the treatment of patients with PAH (WHO Group 1).

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.

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

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Evidence of a personally signed and dated informed consent document exists indicating that the patient has been informed of all pertinent aspects of the study prior to initiation of any study-related procedures.
  2. Patient is willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.
  3. Patient has fulfilled all entry criteria at the time of enrollment in original study with LIQ861.
  4. Patient has completed the protocol defined end of study procedures or met a protocol-defined and adjudicated endpoint in the original LIQ861 study in which they were enrolled.
  5. Patient, whether male or female, agrees to use a medically acceptable method of contraception throughout the entire study period from informed consent through the termination visit, if the possibility of conception exists. Eligible male and female patients must also agree not to participate in a conception process (e.g., actively attempt to become pregnant or to impregnate, sperm donation, in vitro fertilization) during the study and for 30 days after the last dose of LIQ861.

Exclusion Criteria:

  1. Patient prematurely discontinued LIQ861 due to a drug-related AE/SAE or tolerability issue in the original LIQ861 study in which they were enrolled, or patient did not complete protocol defined study procedures at an end of study visit (not Early Termination visit) in their original LIQ861 study.
  2. Patient withdrew consent during participation in another LIQ861 study.
  3. Patient is a female who wishes to become pregnant or who has a positive pregnancy test on Day 1 (LTI-302 Study Initiation Visit).
  4. Patient has undergone lung or heart/lung transplant or the initiation of parenteral (intravenous [IV] infusion or subcutaneous injection) therapy with a prostacyclin during the time since participation in their original LIQ861 study.
  5. Any reason exists that, in the opinion of the Investigator or Medical Monitor, precludes the patient from participating in the study, e.g., any previous or intercurrent medical condition that may increase the risk associated with study participation or that would confound study analysis or impair study participation or cooperation.

How is the study designed?

Design Details

  • Primary Purpose: Treatment
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

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.

Experimental: LIQ861 Inhaled Treprostinil
LIQ861 inhaled treprostinil at capsule strengths of 25 μg, 50 μg, 75 μg and 100 μg. LIQ861 will be administered using the RS00 Model 8 dry powder inhalation (DPI) device (Plastiape S.p.A.; Osnago, Italy) at dose levels of 25 μg capsule strength to 200 μg capsule strength treprostinil four times a day (QID) in individual patients. Titrating to dose levels beyond 200 μg capsule strength QID, under clinical investigator supervision, requires review and approval from the Medical Monitor.
Drug: LIQ861 Inhaled Treprostinil
LIQ861 bulk powder is generated from a treprostinil/excipient matrix from which particles of precise size and shape are created and filled into a hydroxypropyl methylcellulose (HPMC) capsule (size 3). LIQ861 capsules are provided in capsule strengths of 25 μg, 50 μg, 75 μg and 100 μg treprostinil.
Other Names:
  • Inhaled treprostinil
  • Inhaled prostacyclin
