Description of intervention(s) / exposure
Treatment: Drugs - Bosutinib
Treatment: Drugs - Capecitabine
Experimental: 1 - In part 1 (phase 1), ascending and descending multiple oral doses of bosutinib + capecitabine. Doses in part 1 include capecitabine 750 mg/m2 BID on days 1-14 + bosutinib 200 mg QD; capecitabine 625 mg/m2 BID on days 1-14 + bosutinib 300 mg QD. Depending on safety, capecitabine can also be administered at 1000 mg/m2 BID and bosutinib can be administered at 200 mg/m2 QD. The MTD of the combination treatment determined from part 1, will be administered in part 2 (phase 2).
Treatment: Drugs: Bosutinib
Doses in part 1 include bosutinib 200 mg QD; bosutinib 300 mg QD. Depending on safety bosutinib can be administered at 200 mg/m2 QD. The MTD of the combination treatment determined from part 1, will be administered in part 2 (phase 2).
Treatment: Drugs: Capecitabine
Doses in part 1 include capecitabine 750 mg/m2 BID on days 1-14; capecitabine 625 mg/m2 BID on days 1-14. Depending on safety, capecitabine can also be administered at 1000 mg/m2 BID. The MTD of the combination treatment determined from part 1, will be administered in part 2 (phase 2).

Maximum Tolerated Dose (MTD) - Part 1
Query!
Assessment method [1]
0
0
The MTD contour is defined as the dose combinations that achieve a toxicity rate (dose-limiting toxicity [DLT] rate) of less than (<) 1/3. The observed toxicity rates for all the reporting groups (to which at least 1 cohort of participants was allocated) was estimated by calculating the proportion of DLTs observed in the first 21 days of treatment at those reporting groups. DLT includes grade (Gr) 3/4 nausea, vomiting, diarrhea, or asthenia more than 3 days, Gr 4 hematologic toxicities, delayed study treatment administration due to dose toxicities by more than 3 weeks. Pre-defined criterion for MTD: if a higher dose level of capecitabine existed such that the same dose level of bosutinib had a DLT rate of <1/3, no MTD was recommended for that capecitabine dose and if even the lowest dose of bosutinib achieved a toxicity rate of greater than (>) 1/3, no MTD was recommended for that capecitabine dose level.

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to 28 days after last dose that were absent before treatment or that worsened relative to pretreatment state.

0
Percentage of participants with objective response based assessment of confirmed complete response (CR) or confirmed partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST v1.0). Confirmed responses are those that persist on repeat imaging study at least 4 weeks after initial documentation of response. CR is defined as the disappearance of all lesions (target and/or non target). PR are those with at least 30 percent (%) decrease in the sum of the longest dimensions (LDs) of the target lesions taking as a reference the baseline sum LDs.

Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Clearance was estimated from population pharmacokinetic (PK) modeling. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

Summary
Brief summary
This is a research study in 2 parts assessing the following parameters of the combination of
the study drug called bosutinib, and a drug called capecitabine: the safety, how well the
subject's body handles the study drug, and preliminary anti-tumor activity as treatment for
different types of cancers in part 1, and breast cancer only in part 2.
In part 1, subjects will receive bosutinib and capecitabine daily at different dose levels of
each drug in order to determine the highest tolerated dose of the combination study
treatment. In part 2, subjects will receive bosutinib and capecitabine at this highest
tolerated dose to see how well the study treatment works to treat breast cancer. In addition,
genetic research testing (research analyses involving genes and gene products) will be
performed on biological samples from subjects.
