4 Drug and Medication Information
4.1 Drug Indication

Used in patients who are intolerant and/or resistant to two or more tyrosine kinase inhibitors used to treat accelerated or chronic phase CML.


FDA Label


Philadelphia chromosome positive chronic myeloid leukaemia in patients who have the T315I Bcr-Abl kinase domain mutation and who are resistant to prior imatinib therapy.


5 Pharmacology and Biochemistry
5.1 Pharmacology

The pharmacodynamics of homoharringtonine is not fully understood. It is known that homoharringtonine is involved with protein synthesis inhibition and this leads to its antineoplastic activity.


5.2 MeSH Pharmacological Classification

Antineoplastic Agents, Phytogenic

Agents obtained from higher plants that have demonstrable cytostatic or antineoplastic activity. (See all compounds classified as Antineoplastic Agents, Phytogenic.)


Protein Synthesis Inhibitors

Compounds which inhibit the synthesis of proteins. They are usually ANTI-BACTERIAL AGENTS or toxins. Mechanism of the action of inhibition includes the interruption of peptide-chain elongation, the blocking the A site of ribosomes, the misreading of the genetic code or the prevention of the attachment of oligosaccharide side chains to glycoproteins. (See all compounds classified as Protein Synthesis Inhibitors.)


5.3 ATC Code

L - Antineoplastic and immunomodulating agents

L01 - Antineoplastic agents

L01X - Other antineoplastic agents

L01XX - Other antineoplastic agents

L01XX40 - Omacetaxine mepesuccinate


5.4 Absorption, Distribution and Excretion

Absorption

Homoharringtonine absorption was not quantified, but maximum concentration is reached after about 30 mins.


Route of Elimination

The main route of elimination for homoharringtonine is still unknown, but renal elimination is less than 15%.


Volume of Distribution

Homoharringtonine has a steady state Vd of 141 93.4 L.


Clearance

Clearance for homoharringtonine was not quantified.


5.5 Metabolism/Metabolites

Homoharringtonine has undergoes little hepatic metabolism and is mostly metabolized to 4-DMHHT by plasma esterase hydrolysis.


5.6 Biological Half-Life

Homoharringtonine has a half life of about 6 hours after subcutaneous administration.


5.7 Mechanism of Action

Homoharringtonine inhibits protein synthesis by not directly binding to Bcr-Abl. It binds to the A-site cleft in the large ribosomal subunit, which affects chain elongation and prevents protein synthesis.
