Active clinical trials for "Pituitary Diseases"

This is an open-label, prospective, multicentric, non-comparative, non-randomized Phase IV interventional study in which subjects pre-diagnosed with Growth Hormone Deficiency (GHD) were treated for 4 weeks with Saizen to compare the response between GHD children born appropriate for gestational age (AGA) and those born small for gestation age (SGA) after 4 weeks of Saizen therapy.

The main purpose of this study is to establish an optimal monitoring regimen in NutropinAq treated children, using newly developed capillary blood spot IGF-1 measurement technology.

This study assessed pasireotide LAR efficacy on patients with non-functioning pituitary adenomas concerning tumor growth.

Some women cannot have children because they cannot produce enough follicle stimulating hormone (FSH) and luteinising hormone (LH). When this happens the ovaries fail to produce an egg during the menstrual cycle - a condition known as anovulation. Anovulation can be treated by giving replacement FSH and LH. Pergoveris is a medication that contains both FSH and LH. It is used for the treatment of anovulation in women who do not produce enough FSH and LH. A new, liquid formulation of Pergoveris is being tested in this study. It will be compared with the current freeze-dried marketed formulation to see if the new formulation gets into the blood stream as easily as the current formulation. This study will involve 38 healthy female subjects and 2 treatment periods and will last for approximately 77 days. Each subject will receive a single dose of the new liquid formulation and a single dose of the current marketed formulation separated by an interval of two weeks in a randomised (by chance) order. Blood samples will be taken at regular intervals over 2 weeks after each dose to measure levels of FSH and LH. To participate female subjects must have normal ovaries on internal ultrasound scan, a normal result from a cervical smear test, be taking the combined oral contraceptive (OC) pill. Eligible subjects will have their usual OC pill replaced with another called Marvelon throughout the study. After 14 days subjects will have their levels of FSH and LH checked and if sufficiently reduced will only then proceed to dosing. Subjects will then receive one of the formulations. An ultrasound scan of the ovaries will be performed 7 days later, and another one 7 days later just before the next dose. Subjects whose ovaries show signs of stimulation will not be given the second dose. The ultrasound scan will be repeated 7 days after the second dose.

To evaluate efficacy, safety, pharmacokinetics and pharmacodynamics of pasireotide LAR in Japanese patients with active acromegaly or pituitary gigantism. Primary objective was to assess the total-group efficacy of pasireotide LAR on the reduction of mean GH levels to < 2.5 µg/L and the normalization of insulin-like growth factor-1 (IGF-1) at 3 months of study treatment.

This is an open-label, parallel-group, randomized, multicenter Phase III trial to compare the efficacy and safety of a single 250 microgram (mcg) subcutaneous dose of MSJ-0011 to a single 5,000 international units (IU) intramuscular dose of urinary human chorionic gonadotropin (hCG) in inducing ovulation in Japanese women diagnosed with anovulation or oligo-ovulation. Ovulation induction therapy will be undertaken with follitropin alfa. The primary objective is to show that MSJ-0011 is non-inferior to urinary hCG, as assessed by the ovulation rate.

A 26 week trial of TransCon hGH, a long-acting growth hormone product, administered once-a-week. Approximately 150 children (males and females) with growth hormone deficiency (GHD) will be included. All study participants will receive TransCon hGH. This is a global trial that will be conducted in, but not limited to, the United States, Canada, Australia, and New Zealand.

Clinically nonfunctioning pituitary adenoma remains the only pituitary tumor subtype for which no effective medical therapy is available or recommended. We will evaluate the use of cabergoline in a clinical trial, in order to define the efficacy of this treatment in nonfunctioning pituitary adenoma.

The aim of the project is to compare the effect of different extent of resection of the posterior part of the septum on the postoperative nasal functions.

This study focuses on new therapies for a challenging disease in pituitary medicine, that of aggressive pituitary tumors which have limited therapeutic options beyond standard surgical, radiotherapy, and select medical therapies, each incurring significant morbidity and mortality, and each not optimally effective. To improve this gap in knowledge, we seek to translate findings from the laboratory into clinical practice and hone in on therapies directed at pituitary molecular targets, namely ErbB receptors. We have shown that human prolactinomas express nuclear EGFR and membranous ErbB2, ErbB3 and ErbB4, and expression correlates with tumor invasion. Pituitary tumor cell lines transfected with EGFR and ErbB2 translated to downstream effects on prolactin (PRL) gene expression and secretion,as well as cell proliferation. Animal models implanted with these cell lines developed larger tumors and PRL elevations. Treatment with ErbB tyrosine kinase inhibitors (TKIs) led to regression of tumors xenografted into these animals and attenuated PRL secretion. Primary culture of human prolactinomas confirmed expression of ErbB receptors and inhibitory effects of TKIs on PRL secretion and cell proliferation. Based on these exciting preliminary data, the objective of this new proposal is to conduct a Phase IIa clinical trial as a trenchant test of our translational hypothesis that tyrosine kinase inhibition constitutes highly effective targeted biologic therapy for these hitherto refractory pituitary adenomas. Specifically, our aims are to test the: 1) efficacy of TKI therapy with a clinical trial; 2) threshold level of tumor receptor expression to achieve TKI clinical response. Nineteen subjects will be treated with lapatinib for 6 months in combination with their current dopamine agonist therapy, with monthly measurements of PRL levels and MRI imaging every 3 months to evaluate the primary endpoints of achieving 40% reduction in tumor size and 50% reduction in PRL and secondary endpoints of radiologic stabilization and/or reduction and PRL normalization. Mean ErbB receptor protein expression will be compared between responders to lapatinib and non-responders by immunohistochemistry in pituitary tumor samples of these subjects collected from prior surgeries.
