HSP-990 is an oral Hsp90 inhibitor being developed by Novartis in a collaboration with Vernalis. It is also known by NVP-HSP990. HSP-990 is an inhibitor of human heat-shock protein 90 (Hsp90) with potential antineoplastic activity. Hsp-990 binds to and inhibits the activity of Hsp90, which may result in the proteasomal degradation of oncogenic client proteins, including HER2/ERBB2, and the inhibition of tumor cell proliferation. Hsp90, upregulated in a variety of tumor cells, is a molecular chaperone that plays a key role in the conformational maturation, stability and function of oncogenic signaling proteins, such as HER2/ERBB2, AKT, RAF1, BCR-ABL, and mutated p53, as well as many other molecules that are important in cell cycle regulation and/or immune responses.

Sample Use Guides

In Vivo Use Guide

Heat-shock protein 990 was administered orally once or two times weekly on a flat dosing scale and treatment cycles were of 28 days duration. Heatshock protein 990 was supplied as 1, 2.5, 20 and 50mg hard gelatin capsules. Fasting conditions were required (study drug was taken 30 min after a light breakfast, followed by a 3-h fasting period). The twice-weekly dosing schedule required at least 72 h between the two doses, with both doses taken within a 7-day period. Administration of HSP990 was allowed until disease progression, unacceptable toxicity, investigator’s decision or patient withdrawal of consent.

Route of Administration: Oral

In Vitro Use Guide

GTL-16 Cells (1x103) were plated into 96 well tissue culture plates and cultured at 37 C, 5% CO2. Serially diluted HSP990 (up to 1 mkM) were added to the cells and were incubated for 72 hrs. at 37 C, 5% CO2. Cell proliferation was determined using Promega's CellTiter-Glo® Luminescent Cell Viability assay.
