Versartis Trial in Pre-pubertal Japanese Children With Growth Hormone Deficiency (GHD) to Assess Long-Acting Growth Hormone (Somavaratan, VRS-317)

July 22, 2022 updated by: Versartis Inc.

A Randomized, Phase 2/3, Open-Label, Multi-center Study of the Pharmacokinetics, Pharmacodynamics, Safety and Efficacy of A Long-acting Human Growth Hormone (Somavaratan, VRS-317) in Pre-pubertal Japanese Children With Growth Hormone Deficiency (GHD)

The trial will consist of three stages: 1) a 30 day Phase 2 PK and PD evaluation of somavaratan, 2) an optional Phase 2 Extension and 3) a 12 month Phase 3 safety and efficacy stage. Upon completion of the PK/PD stage, the PK/PD profiles for the GHD children in this study will be compared to the PK/PD profiles for the GHD children treated in the Western study Phase 1b/2a study (Protocol 12VR2) and identify the somavaratan dose to be used in the Phase 3 stage in Japan. The Phase 3 stage will continue dosing for 12 months to obtain safety and efficacy data on 48 subjects.

Detailed Description

The trial will consist of three stages: 1) a 30 day Phase 2 PK and PD evaluation of somavaratan, 2) an optional Phase 2 Extension and 3) a 12 month Phase 3 safety and efficacy stage. The study is a randomized, multi-center, open label study. The primary endpoint is height velocity at 12 months.

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
