Active clinical trials for "Acromegaly"

Acromegaly is a rare disorder characterized by excessive production of growth hormone most often by a pituitary adenoma. A pituitary adenoma is a tumor, almost always benign or non-cancerous, that grows on the pituitary, a small gland located at the base of the brain. Treatment of acromegaly usually involves surgery, medication, or radiation, but can involve a combination of these three treatments. Subjects for this study will be recruited if they are: Adults, male or female, between the ages of 18-90. Have been diagnosed with acromegaly, based on elevated levels of growth hormone, IGF-I (a hormone made in response to growth hormone), and a pituitary adenoma visualized on an MRI. Patients would have already agreed to have their acromegaly treated with surgery prior to study entry. Subjects will have measurements of growth hormone using an oral glucose tolerance test (OGTT), IGF-I, free IGF-I and levels of IGF binding proteins at four time points after their pituitary surgery: Day 1, Day 42 (6 weeks), Day 84 (12 weeks), and day 365 (1 year). Subjects will also have an MRI of the pituitary done at 12 weeks and 1 year. OGTT and IGF-I are routinely measured to assess whether or not a person is cured of their acromegaly. An MRI of the pituitary is routinely done at 12 weeks and 1 year after surgery to assess the results of surgery. Free IGF-I and IGF binding proteins are not routinely measured after surgery, but are being done to see if they relate more strongly to disease activity than IGF-I and growth hormone. OGTT and the IGF-I binding proteins are not routinely measured on the day after surgery, but are being done to examine the predictive ability of these tests at a very early time after surgery. Data obtained from these tests will be compared to the data gathered at the 1 year time point. IGF-I and growth hormone will be measured by a commercial clinical lab, Quest Diagnostics, for clinical decision-making at the time of service. IGF-I and growth hormone will also be measured using other methods to attempt to investigate the variability of these hormones when different assays are used.

This study aims to assess the one-year effectiveness and safety of LAN among patients with acromegaly in China in routine clinical practice. In addition, the study is designed to understand the real-world treatment patterns and outcomes of LAN among Chinese patients with acromegaly.

Since protein and AAs are master regulator of GH and IGF-I secretion, we hypothesized that a low protein diet could reduce GH and IGF-I levels in acromegalic patients in addition to conventional therapy. Furthermore, we aim to explore metabolomic, microbiota, and micro-vesicle fingerprints of GH hypersecretion during conventional therapy and after a low protein diet

Non-interventional observational study, to identify safety and effectiveness of Somavert during the post-marketing period based on the Korean RMP as required by the regulations of Ministry of Food and Drug Safety (MFDS)

ACRODAT® is a new software medical device developed by a group of acromegaly experts to help practising endocrinologists assess disease activity in patients with acromegaly. It uses 5 key parameters (IGF-I level, tumour status, comorbidities, symptoms and Quality of life) to evaluate the patient's health status. The purpose of this post marketing surveillance study is to prospectively evaluate whether patients monitored by ACRODAT® with appropriate clinical decisions based on disease activity status will benefit from improved treatment outcomes both in the short and in the long term.

There is a variety of tumors affecting the pituitary gland in childhood; some of these tumors (eg craniopharyngioma) are included among the most common central nervous system tumors in childhood. The gene(s) involved in the pathogenesis of these tumors are largely not known; their possible association with other developmental defects or inheritance pattern(s) has not been investigated. The present study serves as a (i) screening/training, and, (ii) a research protocol. As a screening and training study, this protocol allows our Institute to admit children with tumors of the hypothalamic-pituitary unit to the pediatric endocrine clinics and wards of the NIH Clinical Center for the purposes of (i)<TAB>training our fellows and students in the identification of genetic defects associated with pituitary tumor formation, and (ii)<TAB>teaching our fellows and students the recognition, management and complications of pituitary tumors As a research study, this protocol aims at (i)<TAB>developing new clinical studies for the recognition and therapy of pituitary tumors; as an example, two new studies have emerged within the context of this protocol: (a) investigation of a new research magnetic resonance imaging (MRI) tool and its usefulness in the identification of pituitary tumors, and (b) investigation of the psychological effects of cortisol secretion in pediatric patients with Cushing disease. Continuation of this protocol will eventually lead to new, separate protocols that will address all aspects of diagnosis of pituitary tumors and their therapy in childhood. (ii)<TAB>Identifying the genetic components of pituitary oncogenesis; those will be investigated by (a) studying the inheritance pattern of pituitary tumors in childhood and their possible association with other conditions in the families of the patients, and (ii) collecting tumor tissues and examining their molecular genetics. As with the clinical studies, the present protocol may help generate ideas for future studies on the treatment and clinical follow up of pediatric patients with tumors of the pituitary gland and, thus, lead to the development of better therapeutic regimens for these neoplasms.

This study is a prospective, noninteractive, observational, and longitudinal study aimed at assessing the treatment pattern and clinical outcome of acromegaly in China.

The research is aimed at identifying new predisposition genes for endocrine tumours. Our focus initially is on pituitary adenomas including growth hormone-secreting tumors (somatotrophinomas) and prolactin secreting tumours (prolactinomas), but we wish to extend work to other pituitary tumour cases/families. The recruitment process will be as follows. We will recruit patients from our own Endocrine outpatient clinics and inpatient wards. In addition we will ask colleagues in other Endocrinology Departments (or other specialties such as Clinical Genetics,Pathology, General Medicine ) to identify potentially suitable patients with endocrine & pituitary tumours from their records. We shall focus on patients with good evidence of inheritance of their condition: relatively early onset; or multiple lesions; or other affected family members. Conditions where the predisposing genes have been identified (principally MEN) will be excluded from study. Patients directly contacting us can also enter the study. The Consultant looking after the patient will contact the patient to initially inform him/her of the study. We will then contact the patient (generally by telephone) to discuss the study and what it would entail in terms of information and samples. Subject to agreement in (3), patient will receive 'Information Sheet for patients with pituitary tumour' and 'Consent Form' and will have blood sampling in Consultant's clinic. We will contact additional family members (if appropriate) after an initial approach by the family member already recruited to the study. The additional family members may have developed tumours similar to those of the proband, or may be unaffected individuals who provide useful information for gene identification purposes (for example, spouses may greatly aid the power of gene mapping by linkage. They will receive the "Information Sheet for family members". analysis). 8. Archival tissue will be obtained from HTA licensed tissue banks. This is an established bank whose licence is primarily for diagnosis but can be used for research. 9. We will undertake laboratory work, such as genetic linkage analysis, candidate gene mutation screening and studies of loss of heterozygosity in tumours, to identify the genes predisposing to the condition, such as the AIP gene. In addition we would like to screen other genes related to the chaperon AIP molecule, such as AhR, and other genes currently identified (PDE4A5, survivin and Tom20 protein) or may not been identified. Blood samples for DNA and RNA will coded with unique ID numbers. Pituitary and other endocrine tumour samples will be collected at surgery and kept in liquid nitrogen or -80 C. They will be coded with unique ID numbers. Candidate gene sequencing will be performed in the Barts and the London Medical School Genome Centre. RNA expression studies from blood or adenoma tissue samples will be performed by RT-PCR. Protein expression studies will be performed by Western blotting or immunohistochemistry. The first gene we wish to study causes familial acromegaly, a disease resulting from a pituitary adenoma secreting growth hormone. To establish if the candidate gene is also causing possibly sporadic (not familial) cases of the disease, samples (blood and tissue) will be collected from patients with sporadic disease and will be analysed as above.

The goal of this observational, cross-sectional study is to study bone quality, joint quality and fall risk in acromegalic patients, compared with healthy controls. The main questions it aims to answer are: what is the optimal method for evaluating bone quality and fracture risk in acromegalic patients? are acromegalic patients at increased risk of falling? is HR-pQCT a feasible method for evaluating acromegalic joint disease? Participants will undergo HR-pQCT scans, DXA scans, OsteoProbe examination and fall risk assessments. Results will be compared to matched healthy controls.
