Fruquintinib, also known as HMPL-013, is an orally available, small molecule inhibitor of vascular endothelial growth factor receptors (VEGFRs), with potential anti-angiogenic and antineoplastic activities.

HMPL-013, a novel small molecule compound that selectively inhibits vascular endothelial growth factor receptor (VEGFR), is in phase III clinical studies at Hutchison MediPharma for the treatment of locally advanced or metastatic colorectal cancer. Phase II clinical trials are also ongoing for the treatment of non-squamous non-small cell lung cancer.

Early clinical development is under way at the company for the treatment of gastric cancer in combination with paclitaxel.

Fruquintinib’s mechanism of action is the inhibition of all three forms of VEGF receptors (VEGFR-1, 2, 3). Competitive advantages over currently marketed therapies are the compound’s unique kinase profile, a highly potent efficacy and excellent kinase selectivity, large safety margin, a broad spectrum antitumor activity and a low cost of goods.
Upon oral administration, fruquintinib inhibits VEGF-induced phosphorylation of VEGFRs 1, 2, and 3 which may result in the inhibition of migration, proliferation and survival of endothelial cells, microvessel formation, the inhibition of tumor cell proliferation, and tumor cell death. Expression of VEGFRs may be upregulated in a variety of tumor cell types.

In 2013, the company entered into a licensing, co-development, and commercialization agreement in China with Eli Lilly.

Angiogenesis is a physiological process of growing new blood vessels from pre-existing vessels. It takes place in a healthy subject to heal wounds, i.e., restoring blood flow to tissues after injury or insult.

Excessive angiogenesis may be triggered by certain pathological conditions such as cancer, age-related macular degeneration, and chronic inflammatory disease. As a result, new blood vessels feed diseased tissues and destroy normal tissues. In cancer, new blood vessels also allow tumor cells to escape into the circulation and lodge in other organs.

Vascular endothelial growth factor (VEGF), a homodimeric glycoprotein, and its receptors, e.g., kinase insert domain receptor (KDR), constitute an important angiogenic pathway. Studies have shown that inhibition of KDR resulted in endothelial cell apoptosis and, thus, suppression of angiogenesis. See Rubin M. Tuder, Chest, 2000; 117: 281. KDR inhibitors are therefore potential candidates for treating an angiogenesis-related disorder.

Chi-Med Says Fruquintinib Successful in Lung Cancer Trial

Written by Richard Daverman, PhD, Executive Editor, Greg B. Scott.

Hutchison MediPharma, a division of Chi-Med reported that fruquintinib met its primary endpoint in a second proof-of-concept China trial, this time as a treatment for advanced non-squamous non-small cell lung cancer. The company said fruquintinib “clearly” met its primary endpoint of  progression-free survival, though specific data are being held for a scientific meeting. In 2013, Hutchison out-licensed China rights for the drug to Lilly. In May, the first proof-of-concept trial triggered two payments from Lilly to HMP totaling $18 million.

EXAMPLE 1 Synthesis of 6-(6,7-dimethoxyquinazolin-4-yloxy)-N,2-dimethylbenzofuran-3-carboxamide:

Figure US20090281130A1-20091112-C00009

To a solution of 4-chloro-6,7-dimethoxyquinazoline (1 equiv.) in 2 ml CH3CN were added 6-hydroxy-N,2-dimethylbenzofuran-3-carboxamide (1 equiv.) and K2CO3 (1.5 equiv.). The mixture was refluxed under stirring for 10 hr. After the solvent was evaporated, the residue was washed with water, dried over MgSO4, filtered, concentrated, and purified by column chromatography to give the title compound in a yield of 85%.

1H NMR (DMSO-d6, 400 MHz) δ: 2.49 (s, 3H), 2.81 (d, J=8.4 Hz, 3H,10), 3.97 (s, 3H), 3.98 (s, 3H), 7.24 (dd, J=2.0, 8.4 Hz, 1H), 7.38 (s, 1H), 7.58 (s, 1H), 7.61 (d, J=2.0 Hz, 1H), 7.79 (d, J=8.4 Hz, 1H), 7.96 (m, 1H), 8.52 (s, 1H).
