PSA is a marker of prostate cancer and a PSA response is defined as a decrease in the PSA value by at least 50% from baseline, for 2 successive evaluations, each at least 2 weeks apart, for a total of 3 measurements.

PSA is a marker of prostate cancer and a PSA response is defined as a decrease in the PSA value by at least 50% from baseline for 2 successive evaluations, each at least 2 weeks apart, for a total of 3 measurements.

PSA is a marker of prostate cancer. The duration of PSA response is measured from the time that the first of the 2 consecutive measurements met the criteria for confirmed PSA response, until the date of the first of the 3 consecutive measurements that confirm PSA progression, or the date of disease progression, or the date of death.

PSA is a marker of prostate cancer. PSA velocity measures the rate of change of PSA values. A decrease in PSA values and hence PSA velocity is an early indicator of potential anti-tumor activity.

PSA is a marker of prostate cancer. A decrease in PSA value is an early indicator of potential anti-tumor activity. Log (PSA) is assumed to have a linear relationship with time. The PSA log slope is defined as the slope of the log PSA line.

PSA is a marker of prostate cancer. PSA doubling time is defined as log 2 divided by the slope of the log PSA line. An increase in PSA doubling time indicates improvement in anti-tumor activity.

Tumor response was defined as the number of participants whose best response was CR or PR, per RECIST: CR: disappearance of all target/non-target lesions; PR: >= 30% decrease in the sum of the LDs of target lesions relative to the baseline sum LD

Disease control rate is defined as the number of participants whose best response was CR, PR or SD, per RECIST: CR: disappearance of all target/non-target lesions; PR: >= 30% decrease in the sum of the LDs of target lesions relative to the baseline sum LD; SD: neither sufficient increase to qualify for PD nor sufficient shrinkage to qualify for PR; PD: defined as appearance of new lesion/s, or >=20% increase in the sum of the LD of target lesions, relative to the smallest sum LD recorded since treatment start, or unequivocal progression of existing non-target lesions.

An improved bone scan was defined as 1 or more of the following: disappearance of at least 1 lesion, no new lesions appearing since the most recent prior assessment, or new pain not developing in an area that was previously visualized. A response is considered confirmed if it is noted on 2 examinations at least 4 weeks apart.

A response is considered confirmed if it is noted on 2 examinations at least 4 weeks apart.

Disease progression: progression of target lesions or unequivocal progression of non-measurable lesions/disease as evaluated by computed tomography (CT) scan or magnetic resonance imaging (MRI), not as evaluated by bone scan (non-measurable lesions included visceral and bone lesions), loss of PSA response (only for participants who achieved a PSA response) or Investigator-defined clinical progression based on physical examination, history, symptoms, and ECOG-PS. For participants who did not progress or die, date of last PSA measurement or tumor assessment was used, whichever occurred first.

Measured from date of first dose to date of first 3 consecutive measurements that confirm PSA progression, date of disease progression,or death date.Disease progression:progression of target lesions or unequivocal progression of non-measurable lesions/disease as evaluated by computed tomography (CT) scan or magnetic resonance imaging (MRI),loss of PSA response or Investigator-defined clinical progression based on physical examination,history,symptoms,and ECOG-PS.For participants who did not progress or die,date of last PSA measurement or tumor assessment was used, whichever occurred first.

FAPSI-8:symptom index of important clinician-rated symptoms/concerns to monitor when assessing value of treatment for advanced prostate cancer. Participants respond to each item on a 5-point Likert-type scale from 0 (not at all) to 4 (very much). GP1:I have lack of energy, GP4:I have pain, GE6:I worry that my condition will get worse, C2: I am losing weight, P2:I have certain areas in my body where I experience significant pain,P3:My pain keeps me from doing things I want to do, P7:I have difficulty urinating, P8:My problems with urinating limit my activities.

The FAPSI-8 is a symptom index comprised of the most important clinician-rated symptoms or concerns to monitor when assessing the value of treatment for advanced prostate cancer. It includes 8 items developed to measure symptoms/concerns specific to prostate cancer such as fatigue, pain (3-items), weight loss, difficulty with urination (2-items) and concerns about the condition becoming worse. Participants respond to each item on a 5-point Likert-type scale from 0 (not at all) to 4 (very much).

AE: any new untoward medical occurrence/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 any AEs were recorded.

Drug-related AEs are those events with a relationship to the study therapy of certain; probable; possible; or missing. Drug-related SAEs are those events with any relationship to the study therapy. Drug-related AEs were graded using the National Cancer Institute (NCI) Common Toxicity Criteria (CTC), version 3.0: Grade 1=mild, 2=moderate, 3=severe, 4=life threatening, 5=death. Participants who discontinued the study due to any drug-related AEs were also recorded.

LDH is a laboratory safety parameter. Normal ranges for LD vary with both age and disease status, and another reason for variation in upper limit of normal (ULN) and lower limit of normal (LLN) is that LD was measured via a local (versus a standardized) laboratory. It is therefore not possible to provide one ULN and LLN for the population.

Participants' urine samples were tested for the presence of blood, glucose and protein. If these substances were present in a participant's urine, the results were given as "positive".

The QT interval is a measure of the time between the start of the Q wave and the end of the T wave in the heart's electrical cycle. QTc is the QT interval corrected for heart rate. A prolonged QT interval is a risk factor for ventricular tachyarrhythmias and sudden death.

uNTx is a measure of bone metabolism. A decrease in the marker relative to baseline indicates a decrease in bone metabolism.

uNTx is a measure of bone metabolism. A decrease in the marker relative to baseline indicates a decrease in bone metabolism.

uNTx is a measure of bone metabolism. uNTx response is defined for participants with baseline uNTx above ULN. It is defined as either on-study uNTx values decreasing to within normal limits or 35% or more decrease in uNTx from baseline, whichever happens first.

uNTx is a measure of bone metabolism.The median number of months of uNTx response was calculated for participants with baseline uNTx =< ULN and uNTx progression during treatment, from first dose of dasatinib to uNTx progression.For participant with baseline uNTx above ULN, it was time from uNTx response to uNTx progression.For participants with baseline uNTx equal to or below ULN or uNTx response and no uNTx progression, the date of last uNTx assessment was used. Duration of uNTx response was not defined for participants with baseline value greater than ULN who never achieved uNTx responses.

BAP is a measure of bone metabolism. A decrease in BAP relative to the baseline indicates decrease in bone metabolism.

BAP is a measure of bone metabolism. A decrease in BAP relative to baseline indicates a decrease in bone metabolism.

BAP is a measure of bone metabolism. A BAP response is calculated for participants with a baseline BAP value > ULN. It is defined as on-study BAP values within normal limits.

The median number of months of the BAP response was calculated for participants with baseline BAP <= ULN, from first dose of dasatinib to the first time BAP is above ULN. For participants with baseline BAP > ULN, it was the time from BAP response to the first time BAP was above ULN. For participants with baseline BAP =< ULN or BAP, and no BAP above ULN, last BAP assessment date was used. The median number of months of response was not defined for participants with baseline value > ULN, that never achieved BAP response.
