Study Of SU011248 In Combination With Docetaxel In Patients With Metastatic Breast Cancer

Median Tmax = time for maximum plasma concentration (Cmax) for SU011248, SU012662, and combined SU011248 and SU012662 (total drug); collected C1D2, C2D3. Paired observation.

Mean Cmax = maximum plasma concentration for SU011248, SU012662, and combined SU011248 and SU012662 (total drug) measured as nanograms per milliliter (ng/mL); collected C1D2, C2D3. Paired observation; Cmax dose corrected C2D3 (dose correction if predose concentrations of SU011248 or SU012662 were > 5% of Cmax).

Mean AUC24 = area under plasma concentration-time profile from time 0 to 24 hours for SU011248, SU012662, and combined SU011248 and SU012662 (total drug) measured in nanograms times hour per milliliter (ng*hr/mL); collected C1D2, C2D3. Paired observation; AUC24 dose corrected C2D3 (dose correction if predose concentrations of SU011248 or SU012662 were > 5% of Cmax).

Mean AUClast = area under the plasma concentration-time profile from time 0 (predose) to the last measurable concentration; collected C1D2, C2D3. Data did not allow calculation of AUClast; not summarized; AUC summarized in outcome measure: Area under the plasma concentration-time curve from time zero (0) to 24 hours (AUC24): Sunitinib (SU011248), Sunitinib Metabolite (SU012662), and Total Drug PK Parameters.

Mean Ctrough=plasma concentration-time profile at time 0 (predose); collected C1D2, C1D15, and C2D1. Calculated by setting concentration values below the limit of quantification to zero.

Median Tmax = time to maximum plasma concentration (Cmax) for Docetaxel; collected C1D1, C2D1. Paired observation.

Mean Cmax = maximum plasma concentration for Docetaxel; collected C1D1, C2D1. Paired observation; Cmax dose corrected (dose correction if predose concentrations of SU011248 or SU012662 were > 5% of Cmax).

Mean AUC24 = area under the plasma concentration-time profile from time 0 to 24 hours; collected C1D1, C2D1. Paired observation.

Mean AUC48 = area under the plasma concentration-time profile from time 0 to 48 hours; collected C1D1, C2D1. Paired observation.

Mean AUC24_48 = area under the plasma concentration-time profile from 24 to 48 hours; collected C1D1, C2D1. Paired observation.

Mean AUClast = area under the plasma concentration-time profile from time 0 (predose) to the last measurable concentration; collected C1D1, C2D1. Paired observation.

Mean Thalf (t1/2) = terminal elimination half life; collected C1D1, C2D1. Paired observation.

Median time (50 percent [%]) from the first dose of study treatment to the first documentation of objective tumor progression or to death due to any cause, whichever occurs first; based on Investigator assessment. PFS calculated as (Weeks) = (first event date minus first dose date plus 1) divided by 7.

Number of subjects with objective response based on Investigator assessment of confirmed complete response (CR) or confirmed partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST). Confirmed responses are those that persist on repeat imaging study at least 4 weeks after initial documentation of response.

Number of subjects with clinical benefit based on Investigator assessment of confirmed complete response (CR), partial response (PR), or stable disease (SD) according to RECIST for at least 24 weeks on study.

Median duration (50%) of tumor response based on Investigator assessment for a subgroup of subjects with objective disease response: who have not progressed or died due to any cause; with a response and subsequent progression or death due to any cause for duration of response (DR). DR defined as time from start of first documented objective tumor response (CR or PR) to first documented objective tumor progression or death due to any cause, whichever occurs first. DR calculated as (Weeks) = (the end date for DR minus first subsequent confirmed CR or PR plus 1) divided by 7.
