Description
Sources: https://www.ncbi.nlm.nih.gov/pubmed/24944041
Curator's Comment: description was created based on several sources, including: http://adisinsight.springer.com/drugs/800030686 | http://www.pharmacodia.com/yaodu/html/v1/chemicals/86f3f50a6f945bbfa351e55faac043fb.html

PF-04449913 is a potent and selective inhibitor of the Hh signaling pathway through binding to the target, smoothened. PF-04449913 inhibits Hh signaling in vitro and has demonstrated significant antitumor activity in vivo. In the clinic, PF-04449913 is being evaluated both in hematological and solid malignancies, with a phase II trial currently underway in both fit and unfit patients with acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome (MDS). Treatment-related adverse-events were nausea, dizziness, somnolence, QT prolongation and pruritus. Based on pre-clinical assessments, CYP3A4 is believed to be primarily involved in the metabolism of PF-04449913 that is why PF-04449913 plasma exposures and peak concentrations were increased following concurrent administration of ketoconazole (CYP3A4 inhibitor).

Sample Use Guides

In Vivo Use Guide

100 mg daily in 4-week cycles for a total of 4 cycles. Dose escalation to 200 mg will be provided for patients who do not have at least hematologic improvement following 2 cycles, and dose reduction to 50 mg will be permitted for patients with significant toxicity.

Route of Administration: Oral

In Vitro Use Guide

Incubation of primary AML cells with PF‐913 (1 or 5 uM) attenuated Smoothened‐targeting gene transcripts that were activated by the addition of sonic hedgehog, and reduced the fraction of CD34+CD38− cells.
