February 28, 2023 updated by: Celltrion

A Randomized, Double-Blind, Placebo-Controlled, Sequential, Phase I Study to Evaluate Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of CT-G20 in Subjects With Obstructive Hypertrophic Cardiomyopathy

This is a randomized, double-blind, placebo-controlled, sequential, 5-day treatment, ascending dose study in subjects with obstructive HCM aged 18-70 years. The purpose of this study is to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of CT-G20.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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 to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Men or women aged 18 to 70 years, inclusive at Screening
  2. Has established diagnosis of HCM defined by standard criteria as a maximal left ventricular wall thickness ≥15 mm at initial diagnosis in the absence of other causative loading abnormalities capable of producing the magnitude of hypertrophy observed or ≥13 mm if the subject has a family history of HCM
  3. Has LVOT gradient ≥30 mmHg at rest or LVOT gradient ≥50 mmHg with Valsalva maneuver, due to SAM

Exclusion Criteria:

  1. Known infiltrative, genetic or storage disorder causing cardiac hypertrophy that mimics HCM, such as Fabry disease, amyloidosis or Noonan syndrome with LV hypertrophy
  2. History of persistent atrial fibrillation prior to Screening or Baseline
  3. History of paroxysmal atrial fibrillation requiring treatment (e.g., anti-coagulation and/or antiarrhythmic therapy) within 3 months prior to Screening
  4. Recently treated with invasive septal reduction (surgical myectomy or percutaneous alcohol septal ablation) within 6 months prior to Screening or plans to have either of these treatments during the study
  5. Systolic heart failure with ejection fraction <55% or heart failure symptoms of NYHA Class IV
  6. QTcF >480 msec at Screening or Baseline

  7. Presence of diseases classified as significant by the Investigator at Screening or Baseline, including the following but not limited to:

    1. Diabetes mellitus requiring treatment
    2. Moderate or severe renal insufficiency or renal insufficiency with estimated glomerular filtration rate <70 mL/min/1.73m2
  8. Concomitant use of Disopyramide or Ranolazine within at least 7 days or 5 half-lives (whichever is longer) prior to Screening
