Acthrel (Corticorelin Ovine Triflutate) - Summary

 
 



ACTHREL SUMMARY

ACTHREL®
(corticorelin ovine triflutate for injection)
For intravenous injection only
DIAGNOSTIC USE ONLY

ACTHREL® (corticorelin ovine triflutate for injection) is a sterile, nonpyrogenic, lyophilized white cake powder, containing corticorelin ovine triflutate, a trifluoroacetate salt of a synthetic peptide that is used for the determination of pituitary corticotroph responsiveness. Corticorelin ovine has an amino acid sequence identical to ovine corticotropin-releasing hormone (oCRH). Corticorelin ovine is an analogue of the naturally occurring human CRH (hCRH) peptide. Both peptides are potent stimulators of adrenocorticotropic hormone (ACTH) release from the anterior pituitary. ACTH stimulates cortisol production from the adrenal cortex.

ACTHREL® is indicated for use in differentiating pituitary and ectopic production of ACTH in patients with ACTH-dependent Cushing's syndrome.

NEWS HIGHLIGHTS

Clinical Trials Related to Acthrel (Corticorelin Ovine Triflutate)

Dose Response Relationship for Single Doses of Corticotropin Releasing Hormone (CRH) in Normal Volunteers and in Patients With Adrenal Insufficiency [Completed]
Corticotropin Releasing Hormone (CRH) is a hypothalamic hormone made up of 41 amino acids. Amino acids are proteins that when combined make up different substances, like hormones. The order of amino acids in CRH, has been determined, meaning that the hormone can now be synthetically reproduced in a laboratory setting.

When CRH is released from the hypothalamus it stimulates the pituitary gland to secrete another hormone, ACTH. ACTH then causes the adrenal glands to make a third hormone, cortisol. This process is known as the hypothalamic-pituitary-adrenal axis. Problems can occur in any of the steps of this process and result in a variety of diseases (Cushing's Syndrome and adrenal insufficiency).

Researchers hope that CRH created in a laboratory setting, ovine CRH (oCRH) can be used to help diagnose and treat conditions of the HPA axis. This study will test the relationship for single doses of oCRH in normal volunteers and patients with disorders of the HPA axis. The oCRH will be injected into the patients vein as a single injection or slowly through an IV line over 24 hours. The participants will have blood tests taken to measure hormone levels before, during, and after receiving the oCRH.

XERECEPT® (hCRF) for Primary Glioma Patients Requiring Dexamethasone to Treat Peritumoral Brain Edema [Withdrawn]
The purpose of this study is to examine the safety and efficacy of XERECEPT (human Corticotropin-Releasing Factor, or hCRF) compared to dexamethasone in patients with primary malignant glioma who require increased dexamethasone doses to control symptom of peritumoral brain edema.

An Open-Labeled, Extended-Use of XERECEPT (hCRF) for Patients in Studies NTI 0302, 0303, or Other Designated Studies [Recruiting]
The purpose of this study is to examine the long-term safety and tolerability of human corticotropin-releasing factor (hCRF), XERECEPT®, in patients requiring dexamethasone (Decadron) to treat peritumoral brain edema. This open-label, extended-use study is open to all patients who participate in either of the blinded studies, NTI 0302, NTI 0303, or other designated studies, including patients who may have discontinued blinded study medication early but completed the protocol-stipulated follow-up periods.

Tolerability Study of Xerecept� in Pediatric Patients [Recruiting]
This study is being conducted to evaluate the safety and tolerability of Xerecept® in children with central nervous system tumors and to identify appropriate doses of Xerecept® to be used in subsequent pediatric clinical trials.

Effects of Corticotropin Releasing Hormone (CRH) on the Sleep in Patients With Hypopituitarism [Recruiting]
In contrast to healthy subjects, patients with hypopituitarism do not exhibit endocrine responses when hormones are injected. This is at least true for those with a complete insufficiency of the anterior pituitary. For example, administration of corticotropin releasing hormone (CRH) is not followed by an increase of ACTH and cortisol. Therefore, "pure" hormone effects can be investigated.

It is well established that hormones of the hypothalamic-pituitary-adrenal axis are involved in sleep regulation. In rodents, CRH decreased slow wave sleep (SWS). In humans, CRH was reported to increase wakefulness and to decrease SWS and REM sleep. Primary objective was therefore to study the effect of CRH on patients with hypopituitarism.

To date, there is no information on sleep of patients with hypopituitarism. Secondary objective is therefore to compare sleep of patients with hypopituitarism with sleep of age-matched healthy controls.
