Dasatinib

Overall survival is defined as time in months from the randomization date to the date of death due to any cause (in the randomized population). If the patient did not die, survival was censored on the last date he or she was known to be alive.

Cytogenetic response (CyR) is based on the prevalence of Philadelphia positive (Ph+) cells in metaphase from bone marrow (BM) sample. (Ideally, 25 metaphases but at least 20 metaphases from a BM sample were evaluated). Complete Cytogenetic Response (CCyR)=0% Ph+ cells in metaphase in BM. A cCCyR=those in which all measurements up to at least 28 days after the initial response show an equivalent or better CCyR.

Cytogenetic response (CyR) was based on the number of Philadelphia chromosome positive (Ph+) metaphases among cells in metaphase on a Bone Marrow (BM) sample. The criteria for CyR were as follows: Complete cytogenetic response (CCyR): 0% Ph+ cells in metaphase in BM; Partial cytogenetic response (PCyR): \>0 to 35% Ph+ cells in metaphase in BM; Minor cytogenetic response: \>35 to 65% Ph+ cells in metaphase in BM; Minimal cytogenetic response: \>65 to 95% Ph+ cells in metaphase in BM; No cytogenetic response: \>95 to 100% Ph+ cells in metaphase in BM; Best CyR was defined as the best response obtained at any time during the study; MCyR was defined as a best CyR of complete cytogenetic response (CCyR) or partial cytogenetic response (PCyR). Baseline=closest to, but no later than, the first day of study drug for treated participants and closest to, but no later than, the date of randomization, for those who were randomized but who never received treatment, unless otherwise specified.

MaHR defined by either complete hematologic response (CHR) or no evidence of leukemia (NEL). CHR defined as: white blood cells (WBC) ≤ upper limit of normal (ULN); absolute neutrophil count (ANC) ≥ 1,000/mm\^3; platelets ≥ 100,000/mm\^3; no blasts or promyelocytes in peripheral blood (PB); bone marrow (BM) blasts ≤ 5%; \<5% myelocytes plus metamyelocytes in PB; basophils in PB \< 20%; no extra-medullar involvement (including no hepatomegaly or splenomegaly). NEL defined by same criteria as CHR except that platelets and ANC had to satisfy at least one of the following (note that both lower limits had to be satisfied): platelets ≥ 20,000/mm\^3 and \< 100,000/mm\^3; ANC \> 500/mm\^3 and \<1,000/mm\^3. After Year 2, Amendment 3 allowed participants to switch from the BID to the QD dosing schedule. Percentage: number of participants with MaHR/number of randomized participants.

Determine activity of 5-Fluorouracil, leucovorin, and oxaliplatin (FOLFOX) plus dasatinib on progression free survival (PFS) in patients with metastatic pancreatic adenocarcinoma

Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or measurable increase in a non-target lesion, or the appearance of new lesions, or similar definition as appropriate. Proportion progression-free at 16 weeks.From first day of study related treatment with Dasatinib until the date of first documented progression or date of death from any cause, whichever came first.

A "positive effect" will be defined as a complete response, partial response, or stable disease. "Lack of positive effect" will be defined as progressive disease. Subjects with a mixed response should be continued on therapy until they either fulfill the criteria for positive effect or lack of positive effect, with evaluation every 56 days. The disease control (DC) rate was evaluated as a composite endpoint of the treatment effect on four parameters: 1) Prostate-specific antigen (PSA), 2) measurable disease (if present) by RECIST criteria, 3) bone scan, and 4) quality-of-life as measured by the FACT-P questionnaire.

Duration of treatment for participants who received dasatinib treatment for prostate cancer and chronic phase chronic myeloid leukemia who had also participated on prior protocols CA180-227, CA180-363 and CA180-056 investigating dasatinib. Dasatinib tablet administered once a day by mouth.

Major Molecular Response (MMR) rate at 12 months is the percentage of participants who maintain MMR (BCR-ABL transcripts \< 0.1% on the International Scale \[IS\]) at 12 months after Dasatinib discontinuation without restarting Dasatinib

Major Molecular Response, is defined as a 3-log reduction in BCR-ABL transcripts from the standardized baseline, which represents 100% on the international scale, so a 3-log reduction is fixed at 0.1% for MMR; N/A = not applicable. 95% CI is Clopper-Pearson(Exact) two-sided 95% confidence intervals. P-value is based on Cochran-Mantel-Haenszel (CMH) test stratified by Sokal score(high, intermediate, low, and unknown) and time between 3 month molecular analysis and randomization (\<=4 weeks vs \>4 weeks).

3-year EFS rate is defined as the percentage of participants without event after 3 years since the start of study treatment. Events for EFS are defined as ANY first one of the following: * Lack of complete response in bone marrow * Relapse at any site * Development of second malignant neoplasm * Death from any cause

Major Cytogenetic Response (MCyR) rate is defined as the proportion of all treated participants who achieved a complete (0%) or partial (1%-35% Ph+ metaphases in at least 20 metaphases in bone marrow) cytogenetic response, expressed as percentage. The denominator of the MCyR response rate consists of all treated participants in Cohort 1, and the numerator is all participants in Cohort 1 achieving MCyR. 95% confidence interval was calculated by Clopper-Pearson exact method.

Complete Hematologic Response (CHR) rate is defined as the proportion of all treated participants who achieve a confirmed CHR while on-study, expressed as percentage. CHR is defined as including no more than 5% blasts in bone marrow and normal white blood cell count without blasts in peripheral blood, expressed as percentage. The denominator of the CHR response rate consists of all treated participants in Cohort 2, and the numerator is all participants in Cohort 2 achieving CHR. 95% confidence interval was calculated by Clopper-Pearson exact method.

Complete Cytogenetic Response (CCyR) rate is defined as the proportion of all treated participants who achieve a CCyR while on-study, expressed as a percentage.

The denominator of the CCyR response rate consists of all treated participants in Cohort 3, and the numerator is all participants in Cohort 3 achieving CCyR. 95% confidence interval was calculated by Clopper-Pearson exact method.

This endpoint evaluated the progression free survival (PFS) of participants amongst the total evaluable population. Progression free survival (PFS) was defined as the time from randomization to either the date the subject was first recorded as having PD (even if the subject went off treatment because of toxicity), or the date of death if the subject died due to any causes before progression. Participants with no recorded post-baseline tumor assessment had PFS censored at the day of randomization. Participants lost to follow-up were censored at the last date of contact. Participants that had not progressed or died had PFS censored at the date of last follow-up.

CBR=participants with complete response (CR) + participants with partial response (PR) + participants with stable disease (SD) for a length of time greater than, equal to 6 months. CR= Disappearance of all target lesions. No new lesions. PR= At least a 30% decrease in the sum of the longest diameter (LD) of target lesions taking as reference the baseline sum LD. SD= Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD) taking as reference the smallest sum LD since the treatment started. Physical examination,radiological assessment, and bone scans (if applicable) were used to assess outcome.

Major Cytogenetic Response (MCyR) is defined as Complete Cytogenetic Response (CCyR) or Partial Cytogenetic Response (PCyR). CCyR: 0% Ph-chromosome-positive cells in metaphase in bone marrow \[BM\] PCyR: 1-35% Ph-chromosome-positive cells in metaphase in \[BM\].

Tumor response was assessed according RECIST criteria: PR=at least 30% reduction in the sum of the LD of all target lesions in reference to the baseline sum LD, CR=Disappearance of all non-target lesions. Objective tumor response was defined as a PR or CR.

Tumor response was assessed according RECIST criteria: PR=at least 30% reduction in the sum of the LD of all target lesions in reference to the baseline sum LD, CR=Disappearance of all non-target lesions. Percentage of participants with objective tumor response was determined by the number of participants with PR or CR divided by the total number of response-evaluable participants.

DLT was defined as the occurrence of any of the following adverse events or abnormal laboratory value (graded according to the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.03), assessed as possibly, probably or definitively related to study drugs, occurring within the first cycle of study treatment: Need of any dose modification within the first cycle due to toxicity, grade 3 or 4 neutropenia complicated with fever ≥38.5° C or infection, grade 4 neutropenia (absolute neutrophil count (ANC)\<0.5x1000000000/L) of at least 7 days duration, grade 3 thrombocytopenia complicated by hemorrhage, grade 4 thrombocytopenia, any grade 4 non-hematologic toxicity, grade 3 non-hematologic toxicities except nausea, vomiting, or diarrhea that can be controlled by appropriate medical intervention or prophylaxis, inability to resume dosing for cycle 2 at the current dose level within 14 days due to treatment related toxicity.

MTD is determined by testing increasing doses of dasatinib on dose escalation cohorts 3 to 6 patients per dose level. MTD reflects the highest dose tested in which a DLT is experienced by 0 out of 3 or 1 out of 6 patients among the dose levels

The RP2D was decided by the investigators taken into consideration the information obtained in the study and based on the MTD. To define the RP2D, information about toxicity observed during the full treatment were taken into consideration (relative dose intensity and toxicity observed).

Tumor response was assessed using Response Evaluation Criteria In Solid Tumors Criteria (RECIST 1.1) criteria. ORR is defined as the percentage of patients with a Complete Response (CR) or Partial Response (PR) out of the patients who had measurable disease at baseline. Per RECIST, Complete Response (CR) is defined as the disappearance of all target lesions; Partial Response (PR) is defined as an \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.

DLT will be determined based on the incidence and intensity of drug related adverse events (AEs). The following drug-related AEs (whether related to one or both agents) occurring during the first 6 weeks of combined treatment with both dasatinib plus nivolumab (ie, Weeks 3 to 8, inclusive) would be considered DLTs: * Grade 4 hematologic AE lasting \> 7 days despite appropriate medical intervention, except as noted below; * Grade 3 or Grade 4 nonhematologic AE irrespective of duration; * Grade 2 nonhematologic AE lasting \> 7 days despite appropriate medical intervention (exception: asymptomatic laboratory values of Grade 2 which do not require medical intervention); * Any toxicity managed by discontinuation of nivolumab; * Grade ≥ 2 AE not controlled by medical intervention and requiring dasatinib treatment interruption for \> 28 consecutive days; * Grade ≥ 2 AE not controlled by medical intervention and requiring missing 2 consecutive doses of nivolumab.

Any new untoward medical occurrence or worsening of a preexisting medical condition in a clinical investigation subject administered an investigational (medicinal) product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (such as an abnormal laboratory finding), symptom, or disease temporally associated with the use of investigational product, whether or not considered related to the investigational product.

Any untoward medical occurrence that at any dose: results in death, is life threatening, requires in persistent or significant disability/incapacity, is a congenital anomaly/birth defect or is a important medical event.Requires inpatient hospitalization or causes prolongation of existing hospitalization, results.

The number of participants with a shift in laboratory test results from baseline to Grade 3-4 in hematology

The number of participants with an abnormal Liver function test. Aspartate aminotransferase (AST) Alanine aminotransferase (ALT) Upper Limit of Normal (ULN)

Free T3 (FT3) Free T4 (FT4) Lower Limit of Normal (LLN)

The following drug-related adverse events (AEs) occurring in the first 28 days of treatment were considered dose-limiting toxicities (DLT): Grade 4 hematologic AE lasting \>7 days; ≥Grade 3 nonhematologic AE, despite medical intervention; ≥Grade 2 AE uncontrolled by medical intervention and requiring treatment interruption for \>7 days. RP2D was that dose at which ≤1 of 6 patients had a DLT in the first 4 weeks of treatment. If \<3 patients were DLT-evaluable, up to 6 additional patients entered the same dose level. Accrual to a dose level closed if 6 patients were enrolled and \<3 were DLT-evaluable. If ≥3 patients at a dose level had no DLTs when a new patient enrolled, the dose was escalated to next level. If 1 DLT was observed in \<6 patients, ≥6 patients were required; if no additional DLT was observed, the dose was escalated to the next highest level. If ≥2 DLTs were observed in \<6 patients, that level exceeded the RP2D, and the dose was deescalated to the next lowest level.

Overall survival (OS) is the primary endpoint and is defined as the time from study registration to time of death due to any cause. All patients who meet the eligibility criteria, have signed a consent form, and have received at least one dose of the regimens will be considered evaluable. Patients who are lost to follow-up will be censored at the date of their last follow-up. Patients still alive at the time of analysis will be censored. Only Phase II was evaluated for survival

Doselimiting toxicity will be defined as: Adverse event at least possibly related to the study medication. All by CTCAE v3.0 criteria: Greater than or equal to grade 3: diarrhea or skin rash or desquamation or (other) clinically relevant non-hematological adverse event or non-hematologic adverse event at least possibly due to drug therapy. Or greater than or equal to grade 4: neutropenia or leukopenia or thrombocytopenia or radiation dermatitis or hematologic adverse event OR failure to administer greater than 75% of dasatinib TMZ or interruption of RT for more than 5 days due to adverse events.OR severe acute central nervous system deterioration attributable to TMZ, RT and or dasatinib which cannot be controlled with corticosteroid administration. The MTD for this study will be defined as the highest safely tolerated dose level where at most 1 out of 6 patients experience DLT with the next higher dose having at least 2 patients out of a maximum of 6 patients experience DLT.

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.

The RP2D was based on the MTD which was defined as the maximum combined dose producing dose limiting toxicity (DLT) in \< 33% of participants treated at the individual dose levels in the combination. The MTD is considered the last dose level combination tested just below the maximum administered dose (MAD) level combination and for which DLTs were observed in less than or equal to 33% of participants during the escalation and expansion phase. If MTD was not reached Please refer to Outcome Measure 2 for the complete definition of DLT.

MTD was defined by dose-limiting toxicity (DLT) criteria. DLT was defined as grade 4 neutropenia causing treatment interruption for \>14 days, febrile neutropenia, grade 4 thrombocytopenia, grade 3 thrombocytopenia with a bleeding episode requiring platelet transfusion, nausea and/or vomiting despite medical intervention/prophylaxis causing treatment interruption for \>14 days, grade 3-4 asthenia/fatigue, any other grade \>=3 nonhematologic toxicity except alopecia or transient arthralgia/myalgia (unless unresponsive to intervention), or interruption of study drug for \>14 days due to toxicity. When defined, the MTD would serve as recommended Phase 2 dose of each drug in the combination of oral dasatinib and intravenous docetaxel.

Because no dose-limiting toxicities occurred, the recommended dose of dasatinib used in Phase 2 was based on findings from ongoing studies in chronic myelogenous leukemia and experience from the previous Phase 2 study of single-agent dasatinib in chronic refractory prostate cancer. The recommended Phase 2 dose of docetaxel (75 mg/m\^2) was based on the docetaxel package insert.

Safety was assessed from first dose of study drug through at least 30 days after the last dose, until resolution of drug-related toxicity or when toxicity was deemed irreversible, whichever was longer. An adverse event (AE) was considered a dose limiting toxicity (DLT) if it occurred in the first 21 days and was at least possibly related to study drugs and were: Clinically-evident toxicity of Grade \>= 3, or of Grade 2 which required interruption of treatment for \>= 7 days (consecutive or non-consecutive); non-hematologic abnormal laboratory value of Grade \>= 3, or hematologic toxicity of Grade 4, which persisted 7 days; any grade toxicity which in the judgment of the investigator required a dose reduction or removal from further study therapy.

Cytogenetic responses (CyR) are based on the percentage of Philadelphia-positive (Ph+) metaphases among at least 20 metaphase cells in each bone marrow (BM) sample. The criteria for cytogenetic responses are as follows. Best CyR is defined as the best response obtained at any time during the study. Major Cytogenetic Response (MCyR) = Complete Cytogenetic Response (CCyR; 0 Ph+ Cells in Metaphase in BM), and Partial Cytogenetic Response (PCyR; 1 - 35 Ph+ Cells in Metaphase in BM).

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.

The recommended phase 2 dasatinib dose was determined based on efficacy, safety, and pharmacokinetic data obtained at the prespecified dose levels.

Related AE=relationship of certain, probable, possible, or missing. SAE=any untoward medical occurrence that at any dose: results in death, is life-threatening, requires inpatient hospitalization or causes prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, results in development of drug dependency or drug abuse, is an important medical event.

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 AEs were recorded. These data differ from that in the Participant Flow section. This is because the data were collected on 2 different pages of the Case Report Form and were not reconciled.

Drug-related AEs are those events with a relationship to the study therapy of certain; probable; or possible or missing. Drug-related SAEs are those events with any relationship to the study therapy.

Abnormalities were graded per the National Cancer Institute(NCI)Common Toxicity Criteria (CTC), v3.0(Grade 1 = mild, Grade 2 = moderate, Grade 3 = severe, Grade 4 = life threatening). Grade 3 and 4 criteria are as follows: Hemoglobin: Grade 3:6.5 - \<8.0g/dL, Grade 4: \<6.5g/dL. Platelets: Grade 3: 25.0 - \<50.0\*10\^9/L, Grade 4: \<25.0\*10. Absolute Neutrophil Count (ANC): Grade 3: 0.5 - \<1.0\*10\^9/L, Grade 4: \<0.5\*10\^9/L.White Blood Cells (WBC) : Grade 3: 1.0 - \<2.0\*10\^9/L, Grade 4: \<1.0\*10\^9/L.

Abnormalities were graded per the NCI (CTC), v3.0 (Grade 1 = mild, Grade 2 = moderate, Grade 3 = severe, Grade 4 = life threatening). Grade 3 and 4 criteria are as follows: Alanine aminotransferase (ALT): Grade 3: 5.0-20.0 \* ULN (upper limit of normal), Grade 4: \>20.0 \* ULN; Calcium: Grade 3: 6.0-\<7.0 or \>12.5-13.5 mg/dL, Grade 4: \<0.6-\>13.5 mg/dL; Bilirubin: Grade 3: \>3-10 \* ULN, Grade 4: \>10 \* ULN; Creatinine: Grade 3: \>3.0-6.0 \* ULN, Grade 4: \>6.0 \* ULN; Albumin: Grade 3: \<2g/dL (Grade 4 not defined in NCI CTC); Magnesium: Grade 3: 0.6-\<0.8 or \>2.46-6.6mEq/L, Grade 4: \<0.6 or \>6.6mEq/L.

Dose interruptions and reductions were allowed, in order to optimize individual participant's hematologic, cytogenetic, and molecular response while maintaining and evaluating safety and tolerability of long-term exposure to dasatinib. A dose reduction is defined as the administration of a dose at a lower level compared to previous dose and such that reduced dose, or a lower dose, is given at least 4 consecutive times. In determining the reductions, dose level would be compared to the previous non-null dose. Dose interruption is defined as a complete omission of dosing for 4 consecutive times.
