Ecallantide (Kalbitor)

Plasma kallikrein inhibitor for hereditary angioedema.

Mechanism

60-amino-acid recombinant protein that selectively inhibits plasma kallikrein, reducing bradykinin generation during HAE attacks.

Research areas
  • Hereditary angioedema (acute attacks, ≥12 yrs)
Considerations
  • FDA-approved.
  • Boxed warning: anaphylaxis — administer by healthcare professional.

Somatostatin Analog · Oncology
Lanreotide (Somatuline)

Long-acting somatostatin analog for acromegaly and NETs.

Mechanism

Cyclic octapeptide somatostatin analog with high affinity for SSTR2 and SSTR5. Suppresses GH secretion and slows progression of gastroenteropancreatic neuroendocrine tumors.

Research areas
  • Acromegaly
  • Gastroenteropancreatic NETs
  • Carcinoid syndrome
Considerations
