Additional Information

Phase I trials of HMN-214: Thirty-three patients were enrolled onto four dosing cohorts of HMN-214 from 3 to 9.9 mg/m2/d using a continuous 21-day dosing schedule every 28 days, with pharmacokinetic sampling during cycle 1. RESULTS:  A severe myalgia/bone pain syndrome and hyperglycemia were dose-limiting toxicities at 9.9 mg/m2/d. A dose reduction and separate enrollment by pretreatment status (lightly versus heavily pretreated) was undertaken, with one dose-limiting toxicity (grade 3 bone pain) at 8 mg/m2/d. The maximum tolerated dose was defined as 8 mg/m2/d for both treatment cohorts. Dose-proportional increases were observed in AUC but not Cmax. There was no accumulation of HMN-176, the metabolite of HMN-214, with repeated dosing. Seven of 29 patients had stable disease as best tumor response, including 6-month stable disease in a heavily pretreated breast cancer patient. A transient decline in carcinoembryonic antigen in a patient with colorectal cancer was noted. CONCLUSIONS: The maximum tolerated dose and recommended phase II dose of HMN-214 when administered on this schedule was 8 mg/m2/d regardless of pretreatment status. Further development of HMN-214 will focus on patient populations for which high expression of polo-like kinase-1 is seen (i.e., prostate and pancreatic cancer patients).
