Pasireotide
Somatostatin Analog (pan-receptor)Also known as: Signifor · Signifor LAR
A multireceptor-targeted somatostatin analog with broader SSTR binding than octreotide. FDA approved for Cushing's disease & acromegaly refractory to first-line treatment.
Typical Dose
0.3–0.9 mg 2–3x daily (Cushing's, short-acting); 40–60 mg monthly (LAR, acromegaly)
Route
Subcutaneous (short-acting) or IM LAR (acromegaly)
Cycle
Ongoing, defined by indication
Half-life
~12 hours (short-acting); controlled release (LAR)
Storage
Room temperature.
Overview
Pasireotide differs from octreotide & lanreotide by binding somatostatin receptors 1, 2, 3, & 5 (pan-SSTR), compared to the SSTR2/5 selectivity of earlier analogs. This broader receptor binding is the basis for its efficacy in Cushing's disease (driven largely by SSTR5 on corticotroph tumors) & in acromegaly refractory to SSTR2-selective agents.
Quick Start Guide
Physician-administered. Complex dosing & monitoring — endocrinologist required.
Research Indications
Cushing's disease
Most EffectiveFDA approved. Reduces UFC (urinary free cortisol) in Cushing's disease not controlled by first-line treatment.
Acromegaly (refractory)
Most EffectiveFDA approved for acromegaly inadequately controlled by other somatostatin analogs.
