Study to Evaluate the Safety, Tolerability, and Efficacy of LX7101 in Subjects With Primary Open-angle Glaucoma or Ocular Hypertension

August 31, 2015 updated by: Lexicon Pharmaceuticals

A Phase 1/2a, Randomized, Parallel-group, Double-masked, Vehicle-controlled, Dose-frequency Escalation Study to Evaluate the Safety, Tolerability, and Intraocular Pressure (IOP)-Lowering Efficacy of Topically Administered LX7101 in Subjects Diagnosed With Primary Open-angle Glaucoma (POAG) or Ocular Hypertension (OHT)

This Phase 1/2a study is intended to assess the safety, tolerability, and effects on intraocular pressure of two dose levels and two dose frequencies of LX7101 when administered topically in the eyes of patients diagnosed with primary open-angle glaucoma or ocular hypertension.

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.

Study Type

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?
