e. patients with a new diagnosis of pituitary adenoma or other intracranial tumor within 12 months of screening
f. presence of Prader-Willi syndrome, Turner’s syndrome, untreated adrenal insufficiency, active acromegaly in the past 5 years, or active Cushing’s syndrome in the past 1 year
g. patients with known allergy or hypersensitivity to rhGH, HSA, yeast-derived products, or any other component of the formulation
h. patients who are unable to undergo scanning by dual-energy x-ray absorptiometry (DXA) (eg, due to excessive body weight or implanted devices which would interfere with DXA)
i. patients with previous signs or history of increased intracranial pressure (ICP) with rhGH treatment, or documented ICP or signs of ICP on fundoscopic examination at the time of screening (may be performed by investigator or referred to an ophthalmologist) Patients with previous history of ICP due to treated tumors that have resolved can be included in the study.
j. patients with severe, clinically significant, persistent or recurring migraines, edema, or history or presence of carpal tunnel syndrome, or other nerve compression symptoms assessed as clinically important by the investigator
k. patients with untreated or poorly controlled stage 2 hypertension (systolic blood pressure [SBP] =150 mmHg and/or diastolic blood pressure [DBP] =90 mmHg)
l. patients with clinically significant abnormalities on the screening laboratory assessments, electrocardiogram (ECG), or physical examination that would confound the interpretation of the study or put the patient at undue risk of participation in the study as determined by the investigator.
m. patients with type 1 diabetes mellitus or poorly controlled type 2 diabetes mellitus as indicated by a glycated hemoglobin (HBA1c) of =8%
n. patients who use anabolic steroids or corticosteroids except for physiological maintenance doses used as treatment for patients with hormone deficiencies. limited use of low dose glucocorticoid preparations is allowed (eg, topical preparations); inhaled budesonide will be permitted at a dose not to exceed 400 µg/day for 3 days (total <1200 µg/month) or equivalent.
o. patients using weight reducing agents or appetite suppressants
p. women who are pregnant or nursing, or planning pregnancy during the study period
q. patients with active or known history of substance abuse that in the investigator’s opinion would affect compliance with the study
r. patients with known tendency to have injection site lipoatrophy

Primary Outcome(s)

Main Objective: The primary objective of this study is to determine the efficacy of 6 months of treatment with TV-1106 compared with placebo on body fat composition.

Primary end point(s): Efficacy Variables and Endpoints:
The primary endpoint is the change from baseline to week 24 in body fat mass (kg) as measured by DXA.

Secondary Objective: The secondary objectives of the study are to assess additional body composition measures, insulin-like growth factor 1 standard deviation score (IGF-I SDS), quality of life (QOL), the safety, and tolerability of treatment, pharmacokinetics, pharmacokinetic/pharmacodynamic analysis, and pharmacogenomics (PGx) with TV-1106.

Timepoint(s) of evaluation of this end point: Week 24

Secondary Outcome(s)

Secondary end point(s): Efficacy Variables and Endpoints:
The secondary efficacy variables and endpoints for this study are as follows:
- change from baseline to week 24 in total trunk fat (kg) as measured by DXA
- change in IGF-I SDS from baseline to week 24
- change in QOL scores from baseline to week 24 by questionnaire (assessment of GHD in adults [AGHDA])

Other Efficacy Variables and Endpoints:
- change from baseline to week 24 in lean body mass (DXA), percentage body fat (DXA), percentage trunk fat (DXA), and percentage change in trunk fat (DXA)
- proportion of patients with IGF-I SDS within the normal range (-0.5 to +1.5) at week 24
The following endpoints will be analyzed for all patients, and although all patients will receive TV-1106 during the 12-month extension phase, data will be analyzed by the original treatment assignment:
- change from baseline to weeks 24, 48, and 72 in total trunk fat (DXA), lean body mass (DXA), percentage body fat (DXA), percentage trunk fat (DXA), and percentage change in trunk fat from week 24 through 72
- change in IGF-I from baseline to week 24, week 48, and week 72 (IGF-I SDS)
- change in lipids between baseline to week 24 and week 72 (as measured by total cholesterol, low-density lipoprotein [LDL] cholesterol, high-density lipoprotein [HDL] cholesterol, triglycerides, and lipoprotein)
- change from baseline to week 48in QOL as measured by questionnaire (AGHDA) scores

Exploratory Efficacy Variables and Endpoints:
- change from baseline in QOL as measured by questionnaire (EQ5D-5L) scores and injection satisfaction questionnaire at all other time points

Safety Variables and Endpoints:
Safety variables and endpoints will include the following:
- adverse event reports throughout the study
- clinical laboratory test results
- vital sign measurements
- ECG findings and physical examination findings
- concomitant medication usage throughout the study
- changes in replacement hormones (thyroid stimulating hormone [TSH], free T4, total T3)
- glucose homeostasis (HbA1c, fasting blood glucose, and insulin)

Tolerability Variables and Endpoints:
- proportion of patients who prematurely discontinue treatment
- proportion of patients who prematurely discontinue treatment due to adverse events
- time to premature treatment discontinuation
