Tissue Biomarker for Pegvisomant Action

2014-08-27 04:00:23 | BioPortfolio

Summary

Acromegaly is a disease of the pituitary gland that involves the overproduction of growth hormone. The drug works by blocking the binding of growth hormone to growth hormone receptors found in tissues throughout the body. Human studies have evaluated the reduction of IGF-I levels in the blood following pegvisomant treatment, however, no studies have evaluated IGF-I levels in tissues following pegvisomant administration. In this study, we will test a novel tissue biomarker for pegvisomant action, distinct from measuring IGF-I levels in the blood. To this end, we will determine if administration of pegvisomant modifies the expression of IGF-I, IGF-I receptor, growth hormone receptor and GH- and IGF-i-dependent signaling molecules in the colon tissue of patients with acromegaly.

A Study To Compare The Efficacy And Safety Of Pegvisomant To That Of Sandostatin Lar Depot In Patients With Acromegaly

The purpose of the study is to determine if Pegvisomant is more efficacious than Sandostatin LAR Depot in normalizing IGF-I levels in treatment naive patients with acromegaly.

Long Term Study With B2036-PEG

Primary objective: To investigate the efficacy and safety of Pegvisomant in Japanese patients with acromegaly.

Acromegaly Combination Treatment Study

In this study the investigators will evaluate whether combination low dose somatostatin receptor ligand (SRL) and weekly or daily Pegvisomant will attain equivalent control of serum IGF-1 ...

Effectiveness and safety of pegvisomant: a systematic review and meta-analysis of observational longitudinal studies.

Acromegaly is a rare disease that often requires drug treatment to achieve control, with pegvisomant being one of the most widely used therapies. In the present paper, we aimed to obtain evidence rega...

Systemic complications of acromegaly and the impact of the current treatment landscape: an update.

Acromegaly is a chronic systemic disease with many complications and is associated with increased mortality when not adequately treated. Significant advances in acromegaly treatment, as well as in the...

Cancer Incidence in Patients with Acromegaly: A cohort study and meta-analysis of the literature.

Acromegaly has been associated with increased risk of cancer morbidity and mortality, but research findings remain conflicting and population-based data are scarce. We therefore examined whether patie...

NECESSITY OF MULTIMODAL TREATMENT OF ACROMEGALY AND OUTCOMES.

Uncontrolled acromegaly is associated with increased morbidity and mortality. Despite multimodal therapeutic options, adequate control can be challenging and lead to prolonged exposure to growth hormo...

Persistence of Diabetes and Hypertension after Multimodal Treatment of Acromegaly.

Diabetes and hypertension are frequent comorbidities of acromegaly.

Medical and Biotech [MESH] Definitions

The presence of an excessively large tongue, which may be congenital or may develop as a result of a tumor or edema due to obstruction of lymphatic vessels, or it may occur in association with hyperpituitarism or acromegaly. It also may be associated with malocclusion because of pressure of the tongue on the teeth. (From Jablonski, Dictionary of Dentistry, 1992)

A pituitary tumor that secretes GROWTH HORMONE. In humans, excess HUMAN GROWTH HORMONE leads to ACROMEGALY.

A condition caused by prolonged exposure to excessive HUMAN GROWTH HORMONE in adults. It is characterized by bony enlargement of the FACE; lower jaw (PROGNATHISM); hands; FEET; HEAD; and THORAX. The most common etiology is a GROWTH HORMONE-SECRETING PITUITARY ADENOMA. (From Joynt, Clinical Neurology, 1992, Ch36, pp79-80)

A benign tumor, usually found in the anterior lobe of the pituitary gland, whose cells stain with acid dyes. Such pituitary tumors may give rise to excessive secretion of growth hormone, resulting in gigantism or acromegaly. A specific type of acidophil adenoma may give rise to nonpuerperal galactorrhea. (Dorland, 27th ed)

A disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. It is due to upper airway obstruction. The respiratory pauses may induce HYPERCAPNIA or HYPOXIA. Cardiac arrhythmias and elevation of systemic and pulmonary arterial pressures may occur. Frequent partial arousals occur throughout sleep, resulting in relative SLEEP DEPRIVATION and daytime tiredness. Associated conditions include OBESITY; ACROMEGALY; MYXEDEMA; micrognathia; MYOTONIC DYSTROPHY; adenotonsilar dystrophy; and NEUROMUSCULAR DISEASES. (From Adams et al., Principles of Neurology, 6th ed, p395)
