Clinically significant changes in laboratory values and vital signs were reported as AEs or SAEs, as appropriate. Only descriptive analysis.

All Serious Adverse Events were evaluated and reported for all participants receiving QTI571. 16 individual SAEs were observed in 5 subjects.

AUCtau was the area under the curve calculated to the end of the dosing interval, tau. The effect of co-administration of imatinib at two doses (200 and 400 mg) on the pharmacokinetics of bosentan was performed on dose normalized AUCtau of bosentan. A mixed effects linear model was fitted to the log-transformed PK parameters. This model included treatment (i.e., dose of imatinib) as a fixed effect, and participant as a random effect. Estimates for the treatment differences and associated 90% confidence intervals were obtained from the above model. These estimates and confidence intervals were then "back-transformed" to the original scale, giving, for each dose level of imatinib, the ratio of imatinib + co-administered sildenafil and bosentan (test) relative to the co-administered drugs alone (sildenafil + bosentan) (reference).

This standardized walk course was 30 meters in length. During the walk the participant was connected to a portable pulse oximeter via a finger probe. Participants were instructed to walk at a comfortable speed for as far as they could manage in 6 minutes. The total distance walked (in meters) was recorded. Results were compared between the 2 groups.

PFS was defined as the time from the date of randomization to the date of the first documented progression according to the MacDonald criteria, or death due to any cause. MacDonald criteria are standard criteria in neurooncology. Tumor assessment was made according to the adapted MacDonald criteria based on the combined evaluation of 1) assessment of the MRI scan for measurable, evaluable, and new lesions (made by the independent external expert too), 2) overall assessment of neurological performance (made by the investigator), 3) concomitant steroid use (as reported by the investigator).

Recurrence-free survival assessment is based on the radiologic evidence and is defined as the time from the date of first dose of imatinib to the date of the first documented disease recurrence or death due to any cause (event).

Recurrence-free survival (RFS) assessment is based on the radiologic evidence and is defined as the time from the date of first dose of imatinib to the date of the first documented disease recurrence or death due to any cause (event). RFS estimates were summarized using the Kaplan-Meier product-limit method (Kaplan 1958). Censoring rules for RFS with the earliest occurring rule used in the analysis: subjects without objective recurrence of disease who were alive at the time of their discontinuation from study were censored at the end of study date or end of treatment visit date if the subject refused to be followed post treatment and subjects recording antineoplastic therapy during the study were censored on the date of the therapy initiated

The efficacy of oral STI571 in participants with systemic sclerosis is defined by an improvement in MRSS. Skin thickness was assessed clinically in each of 17 body areas and scored using a 0-3 scale, where 0= normal, 1= mild thickness, 2= moderate thickness, and 3= severe thickness (maximum score 51). A higher score indicates greater severity of the disease.

An AE is the appearance or worsening of any undesirable sign, symptom, or medical condition occurring after starting the study drug even if the event is not considered to be related to the study drug. An SAE is defined as an event that is fatal or life-threatening, results in persistent or significant disability/incapacity, constitutes a congenital anomaly/birth defect, requires inpatient hospitalization or prolongation of existing hospitalization, is medically significant, i.e., defined as an event that jeopardizes the patient or may require medical or surgical intervention to prevent one of the outcomes listed above.

Improvement in the Modified Rodnan Skin Score (MRSS) is measured by Mean change (and 95% Confidence Interval) from Baseline mean to Month 12 mean.Measure Description: The Modified Rodnan Skin Score (MRSS) measures dermal skin thickness through the examination of 17 body areas: fingers, hands, forearms, arms, feet, legs, and thighs (in pairs), and face, chest, and abdomen. The skin score is 0 for uninvolved skin through 3 for severe thickening (hidebound skin). The total skin score is the sum of the skin scores of the individual areas. The minimum score is 0 and the maximum score is 51. A higher score indicates greater severity of disease. The mean change in MRSS represents the average change in total skin score from baseline to month 12.

To investigate the effect of a treatment with Imatinib mesylate, Pioglitazone , Etoricoxib, and Dexamethasone in combination with metronomic chemotherapy (Treosulfane) on the PSA response rate in patients with hormone refractory prostate cancer. A patient will be defined as a responder if a PSA decline of at least 50%, which must be confirmed by a second PSA value 4 weeks later, is observed. A patient will be defined as a non-responder if PSA has not decreased during treatment. Non-response is defined as a 25% increase over the baseline on-study which is confirmed (equal or more) by a second value 4 weeks apart. The absolute increase must account for \> 5 ng/ml.

Best overall response (BOR) on treatment was based on RECIST 1.0 criteria. For target lesions, complete response (CR) is complete disappearance of all target lesions and partial response (PR) is at least a 30% decrease in the sum of longest diameter (LD) of target lesions, taking as reference baseline sum LD. CR or PR confirmation required within 4 weeks. Progressive disease (PD) is at least a 20% increase in the sum LD of target lesions from smallest sum LD as reference or the appearance of one or more new lesions. Stable disease (SD) is neither meeting PR or PD. PD for the evaluation of non-target lesions is the appearance of one or more new lesions and/or unequivocal progression of non-target lesions. CR is disappearance of all non-target lesions.

In this analysis patients with all (serious and non -serious) adverse events, and death were reported. See Safety Section.

The Six Minute Walk test was carried out along a course, such as a hospital corridor, measuring at least 20 meters delineated by markers. Patients were instructed to walk at a comfortable speed as far as they could manage in six minutes, resting whenever they needed to. Distance \<500 meters suggests considerable exercise limitation; Distance 500-800 meters suggests moderate limitation; Distance \>800 meters (with no rests) suggests mild or no limitation.

TTP is the amount of time from date of registration to date of first documentation of progression or symptomatic deterioration. For progression, one or more of the following must occur: (1) 20% increase in the sum of longest diameters of target measurable lesions over smallest sum observed (over baseline if no decrease during therapy) using the same techniques as baseline. (2) Increase in PSA by at least 25% from baseline in patients whose PSA did not decrease, and of 50% from nadir in patients whose PSA decreased with a confirmation 3 weeks later. (3) Unequivocal progression of non-measurable disease in the opinion of the treating physician (an explanation must be provided). (4) Appearance of any new lesion/site. (5) Death due to disease without prior documentation of progression and without symptomatic deterioration, which is defined as global deterioration of health status requiring discontinuation of treatment without objective evidence of progression.

objective response according to RECIST and clinical response

Best tumor response was based on the Southwestern Oncology Group (SWOG) criteria. Objective tumor response assessments were categorized according to the following criteria: complete response (CR), partial response (PR), no change or stable disease (SD), progression of disease (PD), unknown where the progression has not been documented and one or more measurable or evaluable sites have not been assessed (UNK), status after resection for progression (RP), status after resection for safety (RS), status after preventive resection (RPR), progressive after first resection (PDR) and not evaluable. Any tumor assessment after surgical resection for preventative reasons was treated like tumor assessments of UNK for calculation of best response. Tumor assessments with current objective status = RP, RS or PDR were treated like assessments with objective tumor status = PD n the calculation of best response.

Response was evaluated from bone marrow aspirates and biopsy samples. Bone marrow cytogenetic studies were performed every 3 months during the core phase of the study, then twice yearly, then annually to evaluate Philadelphia chromosome positive (Ph+). Cytogenetic response was defined as the best response the participant achieved during study. Based on the percentage of Ph+ cells = (positive cells/ examined cells) x100, at each BM assessment the cytogenetic response was classified as: Complete Cytogenetic Response (CCyR):, 0% Ph+ cells; Partial Cytogenetic Response (PCyR):, \>0 - 35% Ph+ cells; Minor: \>35 - 65% Ph+ cells; and Minimal: \>65 - 95% Ph+ cells, None: \>95 % Ph+ cells and Not done: \<20 metaphases were examined and/or response could not be assigned. Major Cytogenetic Response (MCyR) was defined as sum of the CCyR plus PCyR rates.

Hematologic response was evaluated from hematology measurements in the peripheral blood (PB) and bone marrow (BM) and assessments of extramedullary leukemic involvement (EMD) at physical examination. Response was defined as complete hematologic remission (CHR), no evidence of leukemia (NEL), or return to chronic phase (RTC).

Overall survival was defined as the number of events of death, expressed as a percentage, from the start of treatment to death, due to any reason.

Overall survival was defined as the time between start of treatment and death due to any reason. Overall survival for the participants was calculated by Kaplan-Meier estimates per month. The time was censored at the date of last contact for participants who discontinued treatment and were in survival follow-up.

Dose limiting toxicity (DLT) will be assessed using Common Terminology Criteria for Adverse Events (CTCAE) (v4.0.3), unless otherwise specified in the protocol.
