Description
Eribulin is a fully synthetic macrocyclic ketone analogue of marine sponge natural products. Inhibits growth phase of microtubules via tubulin-based antimitotic mechanism, which leads to G2/M cell-cycle block, disruption of mitotic spindles, and, ultimately, apoptotic cell death after prolonged mitotic blockage. It has a role as an antineoplastic agent and a microtubule-destabilising agent. It is a polycyclic ether, a cyclic ketone, a polyether, a primary amino compound, a macrocycle and a cyclic ketal. It is a conjugate base of an eribulin(1+).
Eribulin is a microtubule inhibitor indicated for the treatment of patients with metastatic breast cancer who have previously received at least two chemotherapeutic regimens for the treatment of metastatic disease. Eribulin was isolated from the marine sponge Halichondria okadai. Eribulin is also being investigated for use in the treatment of advanced solid tumors.
Eribulin is a Microtubule Inhibitor. The physiologic effect of eribulin is by means of Microtubule Inhibition.

7.4 Absorption, Distribution and Excretion

Route of Elimination
Eribulin is eliminated primarily in feces unchanged.
Volume of Distribution
43 L/m2 to 114 L/m2
Clearance
1.16 L/hr/m2 to 2.42 L/hr/m2 (dose range of 0.25 mg/m2 to 4.0 mg/m2). [FDA]

7.5 Protein Binding

49 to 65%.

7.6 Metabolism / Metabolites

There are no major human metabolites of eribulin, CYP3A4 negligibly metabolizes eribulin in vitro.

7.7 Biological Half-Life

about 40 hours

7.8 Mechanism of Action

Eribulin inhibits the growth phase of microtubules without affecting the shortening phase and sequesters tubulin into nonproductive aggregates. Eribulin exerts its effects via a tubulin-based antimitotic mechanism leading to G2/M cell-cycle block, disruption of mitotic spindles, and, ultimately, apoptotic cell death after prolonged mitotic blockage.

9 Toxicity

9.1 Toxicological Information

9.1.1 Hepatotoxicity

Eribulin is a cytotoxic chemotherapeutic agent and serum aminotransferase and alkaline phosphatase elevations are common during cyclic therapy of breast cancer and liposarcoma. The reported rates of ALT elevations have ranged from 8% to 83% with values above 5 times the upper limit or normal (ULN) in 2% to 5%. Isolated mention of “toxic hepatitis” have been made in reports of clinical trials of eribulin but no details of the onset, clinical features and course have been published and the role of eribulin in these outcomes is uncertain. Nevertheless, despite high rates of serum enzyme elevations during treatment, cases of clinically apparent liver injury have not been reported in detail and must be rare.

Likelihood score: E* (unproven but suspected cause of liver injury).

9.1.2 Effects During Pregnancy and Lactation

◉ Summary of Use during Lactation

No information is available on the clinical use of eribulin during breastfeeding. The manufacturer recommends that breastfeeding be discontinued during eribulin therapy and for 2 weeks after the last dose.

◉ Effects in Breastfed Infants

Relevant published information was not found as of the revision date.

◉ Effects on Lactation and Breastmilk

Relevant published information was not found as of the revision date.

15 Classification

15.1 MeSH Tree

  • a halichondrin B derivative that suppresses microtubule growth and acts as an antimitotic agent; structure in first source
    MeSH Concept: M0473224
    MeSH Descriptor: C490954

15.2 NCI Thesaurus Tree

  • An analogue of halichondrin B, a substance derived from a marine sponge (Lissodendoryx sp.) with antineoplastic activity. Eribulin binds to the vinca domain of tubulin and inhibits the polymerization of tubulin and the assembly of microtubules, resulting in inhibition of mitotic spindle assembly, induction of cell cycle arrest at G2/M phase, and, potentially, tumor regression.

15.3 ChEBI Ontology

  • A fully synthetic macrocyclic ketone analogue of marine sponge natural products. Inhibits growth phase of microtubules via tubulin-based antimitotic mechanism, which leads to G2/M cell-cycle block, disruption of mitotic spindles, and, ultimately, apoptotic cell death after prolonged mitotic blockage

15.4 WHO ATC Classification System

15.5 FDA Pharm Classes

  • Microtubule Inhibitor [EPC]
  • Microtubule Inhibition [PE]

  • ChEBI
    Chemical Entities of Biological Interest - Dictionary of molecular entities focused on "small" chemical compounds. ChEBI is part of the EMBL-European Bioinformatics Institute.
  • ClinicalTrials.gov
    ClinicalTrials.gov - ClinicalTrials.gov offers up-to-date information for locating federally and privately supported clinical trials for a wide range of diseases and conditions
  • DailyMed

15.7 IUPHAR / BPS Guide to PHARMACOLOGY Target Classification

  • Tubulins are a family of intracellular proteins most commonly associated with microtubules, part of the cytoskeleton. They are exploited for therapeutic gain in cancer chemotherapy as targets for agents derived from a variety of natural products: taxanes, colchicine and vinca alkaloids. These are thought to act primarily through β-tubulin, thereby interfering with the normal processes of tubulin polymer formation and disassembly.

15.8 UN GHS Classification

  • H301: Toxic if swallowed [Danger: Acute toxicity, oral]
  • H301+H311+H331: Toxic if swallowed, in contact with skin or if inhaled [Danger: Acute toxicity, oral; acute toxicity, dermal; acute toxicity, inhalation]
  • H311: Toxic in contact with skin [Danger: Acute toxicity, dermal]
  • H331: Toxic if inhaled [Danger: Acute toxicity, inhalation]
  • H341: Suspected of causing genetic defects [Warning: Germ cell mutagenicity]

  • A comprehensive list of 7074 endocrine disruptors compiled by PARC T4.2., integrating assessments by EU and national regulators, contributions from entities like the European Chemicals Agency (ECHA) and complemented by other potential endocrine disruptors (hormones, bisphenols, etc.). The list also includes potentially active endocrine disruptors screened from all substances in the NORMAN SusDat database (https://www.norman-network.com/nds/susdat/) using VEGA (QSAR) EDC prediction models (https://www.vegahub.eu/about-qsar), in vitro assay data and machine learning predictions from ToxCast.
