Basic Information

• Recruitment Status: COMPLETED

• Total Enrollment: 101 participants
• Study Classification: INTERVENTIONAL

Brief Summary

The diagnosis of growth hormone deficiency (GHD) in adults is established by laboratory testing in patients with an appropriate clinical history of hypothalamic pituitary disease. Two tests that are considered to be gold standard tests for the diagnosis of GHD are the insulin tolerance test (ITT) and growth hormone releasing hormone (GHRH) combined with L-arginine (L-ARG). However, these tests are either bothersome (given intravenously) to the patient or are linked with side effects. Therefore, an orally available compound like AEZS-130 (formerly ARD-07), if demonstrated to be safe and providing adequate sensitivity and specificity could be a welcome alternative and/or complement to the current available tests.

The intent was to recruit 40 adult GHD (AGHD) patients and 40 healthy control subjects into this trial, but the original sponsor (Ardana Biosciences Ltd.) discontinued the study for financial reasons before this was completed. At the time of withdrawal of GHRH from the market in 2008, 42 AGHD patients and 10 normal controls had completed the study at 9 US sites. This study reactivated to complete the remaining 30 matched control subjects.

Additionally upon agreement with the FDA in a Special Protocol Assessment (SPA), 10 additional adult growth hormone deficient and their matched control were planned to be enrolled into this trial for a total treated population of approximatively 100 subjects.

Detailed Description

Thirty control subjects (i.e., without AGHD) were matched to the 30 AGHD patients who were not previously matched. Matching was based upon gender, age, BMI, and estrogen status for females. They received one oral dose of AEZS-130 followed by serial blood draws for growth hormone (GH), insulin-like growth factor 1 (IGF-1) and pharmacokinetic (PK) determinations. There was no cross over due to the unavailability of GHRH (Geref) in the United States. Under Amendment #4 to this protocol, 10 additional AGHD subjects were to be enrolled and matched as described above.

Furthermore, the objective of the study was changed to delete comparison with L-ARG + GHRH.

Conditions

Diagnosis of Adult Growth Hormone Deficiency (AGDH)

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: CROSSOVER
• Primary Study Purpose: DIAGNOSTIC
• Blinding Strategy: NONE

Study Groups

AEZS-130 ( formerly ARD-07)

A single oral administration of AEZS-130 (0.5 mg/kg po) as Growth Hormone Stimulation Test

Group Type: EXPERIMENTAL

AEZS-130 (formerly ARD-07)

Intervention Type: DRUG

A single oral administration of AEZS-130 as Growth Hormone Stimulation Test

L-ARG+GHRH

This trial was set up as a multi-center, randomized, cross-over study investigating AEZS-130 as a Growth Hormone Stimulation Tests in terms of safety and efficacy compared to L-ARG+GHRH. When GHRH became unavailable on the US market, this comparator arm was no longer available, which was addressed by Amendment No. 3 (version 27-March-2010). Control subject enrolled under Amendment No. 3 were not randomized as there was no cross-over due to unavailability of L-ARG+GHRH. These control subjects received only AEZS-130

Group Type: ACTIVE_COMPARATOR

L-ARG+GHRH

Intervention Type: DRUG

A single administration of L-ARG+GHRH (iv bolus) followed by a 30min infusion of L-ARG as Growth Hormone Stimulation Test
