  Purpose

The diagnosis of GH 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 GHRH combined with arginine. 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 AGHD patients and 40 normal 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 is now being reactivated to complete the remaining 30 matched control subjects.

Additionally upon agreement with the FDA in a SPA, 10 additional adult grown hormone deficient and their matched control will be enrolled into this trial for a total treated population approximatively 100 subjects.


Condition Intervention Phase
Diagnosis of Adult Growth Hormone Deficiency (AGDH) Drug: AEZS-130 (formerly ARD-07) Drug: L-ARG+GHRH Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Intervention Model Description:
Multi-center, randomized, open-label, cross-over trial to compare AEZS-130 to an established GH stimulation test, L-ARG+GHRH, in the diagnosis of GH deficiency and in terms of safety. Following Amendment no. 3 (version 27 May 2010) , no cross-over was performed anymore due to unavailability of L-ARG+GHRH) with resulting single arm testing of AEZS-130. Thus, two treatment arms was applicable as long as GHRH as substance was available.
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: A Multi-center, Study Investigating a New, Oral Growth Hormone Secretagogue (GHS)(AEZS 130, Formerly ARD-07) as a Growth Hormone (GH) Stimulation Test in Terms of Safety and Efficacy

Further study details as provided by AEterna Zentaris:

Primary Outcome Measures:
  • Descriptive summaries of the diagnostic performance of AEZS-130 [ Time Frame: March 2011 ]
    Included: ROC AUC, ROC Sensitivity, ROC Specificity, CART misclassification. The primary endpoint for each individual is the peak GH concentration following treatment (AEZS-130 or L-ARG+GHRH).


Secondary Outcome Measures:
  • Peak IGF-1 concentration following treatment [ Time Frame: March 2011 ]
    ROC and CART analyses on IGF-1

  • Sensitivy and specificity [ Time Frame: March 2011 ]
    summarized for demographic, BMI and estrogen status subgroups containing n>10

  • Determinations from CART [ Time Frame: March 2011 ]
    cut-point which minimizes the misclassification of case and control subjects, optimal decision tree which incorporates treatment, age, sex and BMI

  • Safety [ Time Frame: March 2011 ]
    1. Incidence of treatment-emergent AEs
    2. Laboratory findings
    3. Vital signs
    4. ECGs


Enrollment: 100
Study Start Date: June 2007
Study Completion Date: July 2011
Primary Completion Date: July 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: AEZS-130 ( formerly ARD-07)
A single oral administration of AEZS-130 (0.5 mg/kg po) as Growth Hormone Stimulation Test
Drug: AEZS-130 (formerly ARD-07)
A single oral administration of AEZS-130 as Growth Hormone Stimulation Test
Other Name: Test 1
Active Comparator: L-ARG+GHRH
This trial was set up as a multi-center, randomized, cross-over study investigating AEZS-130 as a Growth Hormone Stimultation 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 27Ma 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
Drug: L-ARG+GHRH
A single administration of L-ARG+GHRH (iv bolus) followed by a 30min infusion of L-ARG as Growth Hormone Stimulation Test
Other Name: Test Control

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