Study of Dasatinib (BMS-354825) in Patients With Solid Tumors

MAD: highest dose level at which >=1 DLTs were reported, MTD: dose one step lower than MAD. DLT: any of the following considered related to dasatinib during course 1:Grade 3(dose reduction by 1 dose level)/Grade 4:recurring nausea, vomiting or diarrhea; any other Grade >=3 non-hematologic toxicity except alopecia or fatigue;any grade toxicity requiring two dose reductions or participant's discontinuation; Grade 4 neutropenia <500 cells/mm^3 for >=5 consecutive days or febrile neutropenia; Grade 4 thrombocytopenia <25,000 cells/mm^3 or Grade 3 bleeding requiring platelet transfusion.

AEs: any new untoward medical occurrences/worsening of pre-existing medical condition, whether or not related to study drug. SAE: any AE that resulted in death; was life threatening; resulted in persistent/significant disability/incapacity; resulted in/prolonged an existing in-patient hospitalization; was a congenital anomaly/birth defect; or was an overdose. Participants who discontinued the study due to an AE were recorded. Drug-related AEs: events with a relationship to the study therapy of certain; probable; possible; not likely or unrelated.

Hematology abnormalities were graded per the National Cancer Institute (NCI) Common. Terminology Criteria (CTC) version 3.0 criteria (Grade 1 = mild, Grade 2 = moderate, Grade 3 = severe, Grade 4 = life threatening). Grade 3 and 4 criteria are as follows: Absolute Neutrophil Count (ANC): Grade 3: 0.5 - <1.0*10^9/L, Grade 4: <0.5*10^9/L; lymphocytes: Grade 3: 0.2 - <0.5*10^9/L, Grade 4: <0.2*10^9/L.

Abnormalities were graded according to the NCI CTC, version 3.0 (Grade 1 = mild, Grade 2 = moderate, Grade 3 = severe, Grade 4 = life threatening). Grade 3 and 4 criteria are as follows: phosphorous: Grade 3: 1.0-<2.0 mg/dL, Grade 4: <1.0 mg/dL; calcium: Grade 3: 6.0-<7.0 or >12.5-13.5 mg/dL, Grade 4: <0.6->13.5 mg/dL; magnesium: Grade 3: >3.0 - 8.0 mg/dL or >1.23 - 3.30 mmol/L, Grade 4: >8.0 mg/dL or >3.30 mmol/L; albumin: Grade 3: <2 g/dL or <20 g/L.

Abnormalities were graded according to the NCI CTC, version 3.0 (Grade 1 = mild, Grade 2 = moderate, Grade 3 = severe, Grade 4 = life threatening). Most frequent hematology Grade 3 and 4 abnormalities occurring in >=10% participants were recorded. Grade 3 and 4 criteria are as follows: lymphocyte count: Grade 3: 0.2 - <0.5*10^9/L, Grade 4: <0.2*10^9/L.

Abnormalities were graded according to the NCI-CTC, version 3.0 (Grade 1 = mild, Grade 2 = moderate, Grade 3 = severe, Grade 4 = life threatening). Most frequent (>=10%) serum laboratory abnormalities were recorded. The following definitions specify the NCI-CTC AE criteria for serum laboratory abnormalities in the data presented: magnesium: Grade 3: >3.0 - 8.0 mg/dL or >1.23 - 3.30 mmol/L, Grade 4: >8.0 mg/dL or >3.30 mmol/L.

Interim and final physical examinations were performed. The investigator used his/her clinical judgment to decide whether or not physical examination findings were clinically significant.

Vital signs measurements (including blood pressure, body temperature and pulse rate) were recorded. The investigator used his/her clinical judgment to decide whether or not abnormalities in vital signs were clinically significant.

Standard 12-lead ECG was used to record selected ECG parameters like RR interval (the time between the two R waves in ECG), PR interval (interval measured from the beginning of the P wave to the beginning of the QRS complex; QRS complex is the name for some of the deflections seen on a typical ECG)), QRS duration, QT interval (time between onset of ventricular depolarization and end of ventricular repolarization), QT interval corrected for heart rate using Bazett's (QTcB) and Fridericia's (QTcF) formulas.

QT interval corrected for heart rate (QTcF) was assessed using triplicate 12-lead serial ECGs.

Cmax was obtained from the plasma concentration versus time data after oral administration of dasatinib.

AUC(INF), area under the plasma concentration-time curve from zero to the last time of the last quantifiable concentration within the dosing interval was calculated for Day 1.

Area under the plasma concentration-time curve within the dosing interval was determined. AUC(TAU), from time 0 to the time of the last measurable concentration (24 hours) was calculated for Day 1, 14, 28 respectively.

Tmax, time to reach maximum observed plasma concentration of dasatinib was obtained directly from the plasma concentration versus time data.

T-half of dasatinib was calculated using plasma concentration versus time data.

AI of Dasatinib was calculated as ratio of geometric mean of AUC(TAU) (area under the plasma concentration versus time curve from time 0 to the time of the last measurable concentration) on Day 14 or Day 28 on Day 1.

Apparent oral clearance was obtained from the plasma concentration versus time data.

Apparent volume of distribution after oral dosing was obtained from plasma concentration versus time data.

Maximum plasma concentration was obtained from plasma concentration versus time data of metabolite (BMS-582691).

AUC (0-t) was calculated using plasma concentration values of metabolite at time 0 to the time of the last measurable concentration (t).

Tmax of the metabolite was obtained using plasma concentration versus time data of metabolite BMS-582691.

Urine NTx is a measure of bone metabolism. A decrease in the marker relative to baseline indicates a decrease in bone metabolism. Mean urine concentration of NTx biological marker was determined using enzyme linked immuno-sorbent assay (ELISA).

Urine levels of DPyr is a measure of bone resorption. A decrease in Dpyr relative to the baseline indicates decrease in bone metabolism. Mean urine concentration of Dpyr biological marker was determined using ELISA.

TRACP-5b is a measure of bone metabolism. A decrease in TRACP-5b relative to the baseline indicates decrease in bone metabolism. Serum TRACP-5b was quantified with enzyme-linked-immunosorbent serologic assay (ELISA).

BAP is a measure of bone metabolism. A decrease in BAP relative to the baseline indicates decrease in bone metabolism. Serum BAP was quantified with ELISA.

Src and pSrc protein expression was planned to be evaluated in PBMC for establishing PK/PD relationship between Src/pSrc protein expression in PBMC and exposure of BMS-354825.

Tumor response was defined as the number of participants whose best response was CR or PR as per Response Evaluation Criteria In Solid Tumors (RECIST) criteria. CR: disappearance of all target/non-target lesions; PR: >= 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD.
