Description

Pasireotide is a synthetic long-acting cyclic hexapeptide with somatostatin-like activity. It is marketed as a diaspartate salt called Signifor, indicated for the treatment of adult patients with Cushing’s disease for whom pituitary surgery is not an option or has not been curative. SIGNIFOR is an injectable cyclohexapeptide somatostatin analogue. Pasireotide exerts its pharmacological activity via binding to somatostatin receptors (ssts). Pasireotide binds and activates the hsst receptors resulting in inhibition of ACTH secretion, which leads to decreased cortisol secretion.

Sample Use Guides

In Vivo Use Guide
Recommended initial dosage is either 0.6 mg or 0.9 mg by subcutaneous injection twice a day; recommended dosage range is 0.3 mg to 0.9 mg twice a day
Route of Administration: subcutaneous injection
In Vitro Use Guide
Primary cultures from normal human and rat adrenals were incubated with 10-100 nM Pasireotide with and without 10nM ACTH. Dose-response studies with 1 nM-1 uM Pasireotide were performed on rat adrenals. Cortisol/corticosterone levels in medium were measured after 4 and 24h. Pasireotide (10nM) significantly increased corticosteroid levels after 24h incubation in both human (36.4 ± 0.43 ng/well vs 27.7 ± 3.17 ng/well, p<0.05) and rat (16.2 ± 1.16 ng/well vs 11.6 ± 0.92 ng/well p<0.05) adrenals; lesser effects were observed with 100 nM Pasireotide (33.4 ± 2.59 ng/well vs 27.7 ± 3.17 ng/well p<0.05; 13.4 ± 0.82 ng/well vs 11.6 ± 0.92 ng/well, N.S. vs baseline secretion for human and rat adrenals, respectively). Dose-response curves confirmed maximal effect at 10nM Pasireotide.
