  • In case of use of oral contraception women should have been stable on the same pill for a minimum of 3 months before taking study treatment.
  • Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential.

About this study

Official title: Pilot Study of Pasireotide LAR Treatment of Silent Corticotrophin Pituitary Tumors and Effects on Plasma Levels of POMC

This is a phase II, open-label, 12-month pilot study in 10 patients with silent corticotroph pituitary tumors testing the hypotheses that Pasireotide long-acting release (LAR) treatment of patients with silent corticotroph pituitary tumors and elevated plasma Proopiomelanocortin (POMC) levels will reduce plasma POMC levels and this will be associated with a reduction in pituitary tumor size. Pasireotide LAR 40 mg will be administered monthly. Baseline and monthly visits on therapy will monitor plasma levels of POMC, other pituitary function, safety labs, glucose tolerance, physical examination, and visual fields. Pituitary magnetic resonance imaging (MRI) will be done at baseline, 6 months and 12 months of therapy. The eligible patient population will consist of adult patients with known silent corticotroph pituitary tumors and elevated plasma levels of POMC.

Read the detailed description

Clinically non-functioning pituitary adenomas (CNFAs), the subtype of pituitary adenomas that does not appear to secrete biologically active hormone nor to have a characteristic clinical phenotype, are the most common type of pituitary macroadenoma at diagnosis. There is currently no option for medical therapy of CNFA, in general, or specifically of silent corticotroph tumors. Silent corticotroph tumors can range from being completely asymptomatic to becoming large and causing significant hypothalamic/pituitary dysfunction and visual symptoms, and most data support that this type of tumor has a more aggressive phenotype. Current therapy consists primarily of surgical removal of the tumor and for recurrent or residual tumors, repeated surgery and/or radiotherapy. In very aggressive tumors, chemotherapy has been tried with some success. Therefore, a need exists for a medical therapeutic option for the treatment of this tumor type. This project assesses this clinical need.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Pasireotide LARDrug

    Also called Signifor LAR

    Pasireotide LAR (SIGNIFOR® LAR) is a somatostatin analog indicated for the treatment of patients with acromegaly who have had an inadequate response to surgery and/or for whom surgery is not an option. It is a long acting release injectable suspension for intramuscular use.

    The starting dose is Pasireotide LAR 40 mg/month intramuscular (IM), this will be increased to 60 mg/month at 6 months if a fall in POMC levels and/or tumor shrinkage are not attained.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Pasireotide LAR in people with Pituitary Tumor and ACTH-producing Pituitary Tumour, run by Columbia University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 31 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 27 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 27 Apr 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Plasma Proopiomelanocortin (POMC) Levels (time frame: Baseline, 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Apr 2021.
