Duration of Objective Response (OR) Assessed by the Independent Review Facility Using Response Evaluation Criteria in Solid Tumors (RECIST)

For patients who achieved an objective response, duration of objective response was defined as the time from the first tumor assessment that supported a patient's objective response to the time of disease progression or death on study (ie, death from any cause within 30 days of the last dose of study drug), whichever occurred first. Disease progression was defined as at least a 20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum longest diameter recorded since treatment started or the appearance of 1 or more new lesions or the appearance of 1 or more new lesions and/or unequivocal progression of existing non-target lesions. For participants who experienced no disease progression and did not die while on study, data were censored at the date of the last tumor assessment. Kaplan-Meier methodology was used to estimate the duration of objective response. (NCT00509769)
Timeframe: Randomization until the final analysis cut-off date of 25 Jun 2009 (end of the study, approximately 12 months after the last patient was enrolled, up to 23 months)

Objective Response Assessed by the Independent Review Facility Using Response Evaluation Criteria in Solid Tumors (RECIST)

Objective response was defined as a complete response (CR) or partial response (PR) determined on 2 consecutive occasions ≥ 4 weeks apart, using Response Evaluation Criteria in Solid Tumors (RECIST). CR: The disappearance of all target lesions and all non-target lesions, normalization of tumor marker level, and no new lesions. PR: Disappearance of all target lesions and persistence of ≥ 1 non-target lesions and/or the maintenance of tumor marker level above the normal limits, or, at least a 30% decrease in the sum of the longest diameter of target lesions, and no new lesions or unequivocal progression of existing non-target lesions. (NCT00509769)
Timeframe: Randomization until the analysis data cutoff-dates of 31 Jan 2009 (6 months after the last patient was enrolled in the study) and 25 Jun 2009 (approximately 12 months after the last patient was enrolled in the study, up to 23 months)

Duration of Objective Response (DOR) as Assessed by an IRC

Tumor response was assessed by an IRC according to modified RECIST. DOR was defined as the time from first documented OR to first documented PD or death from any cause, whichever occurred earlier. OR was defined as a CR or PR determined on 2 consecutive tumor assessments at least 4 weeks apart. For TLs, CR was defined as the disappearance of all TLs; PR was defined as >/=30% decrease in the SLD of TLs, taking as reference the baseline SLD; and PD was defined as >/=20% increase in the SLD, taking as reference the smallest SLD recorded since treatment started or the appearance of 1 or more new lesions. For non-TLs, CR was defined as the disappearance of all non-TLs; PR was defined as the persistence of 1 or more non-TLs; and PD was defined as appearance of 1 or more new lesions and/or unequivocal progression of existing non-TLs. The 95% CI was computed using the method of Brookmeyer and Crowley. (NCT00829166)

Duration of Objective Response Assessed by the Investigator Using Response Evaluation Criteria in Solid Tumors (RECIST)

Duration of objective response was defined as the time from initial response to disease progression (PD) or death from any cause. For target lesions, PD was defined as at least a 20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum of the longest diameter recorded since treatment started or the appearance of 1 or more new lesions. For non-target lesions, PD was defined as the appearance of 1 or more new lesions and/or unequivocal progression of existing non-target lesions. Target lesions should be selected on the basis of their size (those with the longest diameter) and their suitability for accurate repeated measurements by imaging techniques or clinically. All measurable lesions up to a maximum of 5 lesions per organ and 10 lesions in total, representative of all involved organs, should be identified as target lesions. (NCT00875979)

Percentage of Participants With CR or PR or Stable Disease (SD) for at Least 6 Months [Clinical Benefit Rate (CBR)] - MBC Population

CBR was defined as percentage of participants experiencing SD of at least 6 months from the start of treatment plus CR or PR according to the RECIST v1.0 criteria. For TLs: CR- disappearance of all TLs. PR- at least 30% decrease in the sum of LDs of the TLs, taking as a reference the BL sum of LDs. PD- at least 20% increase in the sum of LD of TLs, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more lesions. SD- neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD. For NTLs: CR- disappearance of all NTLs and normalization of tumor marker levels. SD- persistence of one or more NTLs and/or maintenance of tumor marker level above the normal limits. Percentage of participants= number of participants with CR/PR/SD divided by total number of participants, and then multiplied by 100. 95% CI was determined using the Pearson-Clopper method.

Percentage of Participants With Progression-Free Survival (PFS) Event - MBC Population

PFS was defined as the time interval between the date of the start of treatment and the date of first documentation of progressive disease (PD) or death from any cause, whichever occurred first. Response was based on Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.0 (v1.0). For target lesions (TLs), PD was at least a 20 percent (%) increase in the sum of longest diameter (LD) of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more lesions. For non-target lesions (NTLs), PD was the appearance of one or more new lesions and/or unequivocal progression of existing NTLs. Data for participants without PD or death was censored at the time of the last response assessment. Percentage of participants with PFS event was calculated as the (number of participants with PFS event [PD or death]) divided by (total number of participants), and then multiplied by 100.

Percentage of Participants With a Best Overall Response (BOR) of Complete Response (CR) or Partial Response (PR) - MBC Population

BOR was defined as CR or PR recorded from baseline until disease progression/recurrence according to RECIST v1.0 criteria. For TLs, CR was defined as the disappearance of all TLs, and PR was defined as at least a 30% decrease in the sum of LDs of the TLs, taking as a reference the baseline (BL) sum of LDs. For NTLs, CR was defined as the disappearance of all NTLs and normalization of tumor marker levels. Percentage of participants with BOR rate was calculated as the (number of participants with CR or PR) divided by (total number of participants), and then multiplied by 100. The 95% confidence interval (Cl) was determined using the Pearson-Clopper method. (NCT00934856)

Percentage of Participants With New Abnormal T Waves

The incidence of abnormal T-wave changes from baseline was determined based on centrally read electrocardiogram (ECG) tracings comparing each of the three triplicate readings from the post baseline ECG time points to the baseline ECG reading. At each time point, if at least one of the three triplicate readings was abnormal, the participant was counted as abnormal for that ECG timepoint as follows: an inverted T, flat T, or biphasic T compared with baseline was considered an abnormal significant change from baseline. Additionally, nonspecific T-wave changes from baseline were considered as abnormal nonsignificant changes from baseline. T-wave changes from baseline due to ventricular conduction or left ventricular hypertrophy strain were considered not evaluable. C=Cycle; D=Day. (NCT00943670)

Time to Deterioration in HRQoL as Assessed by FACT-B TOI-PFB Score

The FACT-B is a self-reported instrument which measures HRQOL of participants with breast cancer. It consists of 5 subscales including PWB, SWB, EWB, FWB, and BCS. The TOI-PFB score is taken by adding the scores from the PWB (7 items), FWB (7 items), and BCS (9 items) subscales. Items are rated from 0 (not at all) to 4 (very much) and a total score is derived. Scores may range from 0 to 92, with higher scores indicating better HRQOL. A 5 point change has been identified as the clinically minimal important difference (CMID) on the FACT-TOI-PFB scale. Time to deterioration was defined as the time from Baseline until the first decrease in FACT-B TOI-PFB score. Median time to deterioration was estimated using Kaplan-Meier analysis, and corresponding CIs were computed using the Brookmeyer-Crowley method. (NCT01120184)

Percentage of Participants With an Objective Response

An objective response was defined as a complete or partial response determined on 2 consecutive occasions ≥ 4 weeks apart using Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. Complete response was defined as the disappearance of all target and non-target lesions. Any pathological lymph nodes (whether target or non-target) must be < 10 mm on the short axis. Partial response was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum. Participants who had no post-baseline tumor assessment were counted as non-responders. (NCT01419197)

Progression Free Survival (PFS) According to Modified Response Evaluation Criteria in Solid Tumors (mRECIST v1.1) - Phase 3

Progression-free survival was defined as the time between the date of randomization and the first date of documented progression or date of death due to any cause, whichever occurred first. Tumor assessment was performed using modified RECIST v1.1. Progressive disease could base on symptom deterioration or was defined as at least a 20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum longest diameter recorded since treatment started or the appearance of one or more new lesions and/or the unequivocal progression of existing non-target lesions. Kaplan-Meier estimates were used for analysis. Cumulative data (up to primary analysis cut-off date of 30-June-2015) are provided for both phase 2 and phase 3 within the results of this measure. The confirmatory analyses are restricted to comparisons between the taxane arm and the selected trastuzumab emtansine arm (2.4 mg). (NCT01641939)

Percentage of Participants With Adverse Events

An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events. AEs, including AEs of Special Interest and AEs of Particular Interest, were reported based on the national cancer institute common terminology criteria for AEs, Version 4.0 (NCI-CTCAE, v4.0). Reported are the number of subjects with AEs, Grade 3-5 AEs, and Serious Adverse Events (SAEs). (NCT01772472)

Change From Baseline of Functional Scales, Symptom Scales and Single Items in European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire - Core 30 (QLQ-C30)

The EORTC QLQ-C30 included global health status, functional scales (physical, role, emotional, cognitive, and social), symptom scales (fatigue, nausea/vomiting, and pain) and single items (dyspnoea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties). Most questions used a 4-point scale (1 'Not at all' to 4 'Very much'; 2 questions used 7-point scale [1 'very poor' to 7 'Excellent']). Scores were averaged and transformed to 0 - 100 scale, whereby higher scores indicate greater functioning, greater quality of life, or a greater degree of symptoms, with changes of 5 - 10 points considered to be a minimally important difference to participants. A positive value means an increase, while a negative value means a decrease, in score at the indicated time-point relative to the score at baseline (Cycle 1, Day 1). (NCT01772472)

Change From Baseline of Four Functioning Scales and Four Symptom Scales in European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire - Breast Cancer (QLQ-BR23)

EORTC-QLQ-BR23 is a 23-item breast cancer-specific companion module to the EORTC-QLQ-C30 and consists of four functional scales (body image, sexual enjoyment, sexual functioning, future perspective [FP]) and four symptom scales (systemic side effects [SE], upset by hair loss, arm symptoms, breast symptoms). Questions used 4-point scale (1=not at all, 2=a little, 3=quite a bit, 4=very much). Scores averaged and transformed to 0-100 scale. High score for functional scale indicated high/better level of functioning/healthy functioning. Higher scores for symptom scales represent higher levels of symptoms/problems. For functional scales, positive change from baseline indicated deterioration in quality of life (QOL) and negative change from baseline indicated an improvement in QOL. For symptom scales, positive change from baseline indicated an improvement in quality of life (QOL) and negative change from baseline indicated a deterioration in QOL. (NCT01772472)

Percentage of Participants With Adverse Events

An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events. AEs were reported based on the national cancer institute common terminology criteria for AEs, Version 4.0 (NCI-CTCAE, v4.0). (NCT01966471)

European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ-C30) Score

The EORTC QLQ-C30 included global health status, functional scales (physical, role, emotional, cognitive, and social), symptom scales (fatigue, nausea/vomiting, and pain) and single items (dyspnoea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties). Most questions used a 4-point scale (1 'Not at all' to 4 'Very much'; 2 questions used 7-point scale [1 'very poor' to 7 'Excellent']). Scores were averaged and transformed to 0 - 100 scale, whereby higher scores indicate greater functioning, greater quality of life, or a greater degree of symptoms, with changes of 7 - 15 points considered to be a clinically meaningful detioration to participants. A positive value means an increase, while a negative value means a decrease, in score at the indicated time-point relative to the score at baseline (Cycle 1, Day 1). (NCT01966471)

EORTC Quality of Life Questionnaire-Breast Cancer 23 (QLQ-BR23) Score

EORTC-QLQ-BR23 is a 23-item breast cancer-specific companion module to the EORTC-QLQ-C30. There are four functional scales (body image, sexual enjoyment, sexual functioning, future perspective [FP]) and four symptom scales (systemic side effects [SE], upset by hair loss, arm symptoms, breast symptoms). Questions used 4-point scale (1=not at all, 2=a little, 3=quite a bit, 4=very much). Scores averaged and transformed to 0-100 scale. High score for functional scale indicated high/better level of functioning/healthy functioning. Higher scores for symptom scales represent higher levels of symptoms/problems. For functional scales, positive change from baseline indicated improvement in quality of life (QOL) while negative change from baseline indicated a deterioration. For symptom scales, positive change from baseline indicated deterioration and negative change indicated improvement. (NCT01966471)

Maximum Tolerated Dose (MTD) of BYL719 in Combination With T-DM1.

"Safety of BYL719 in combination with T-DM1 will be assessed during the first 21 days (1 cycle=21 days) which will assist in providing the MTD. Adverse Events including dose limiting toxicities (DLT), changes in physical findings, or clinical laboratory results as well as cardiac toxicity (changes in cardiac function, which will be measured by use of echocardiogram or MUGA scan) will be evaluated.~For each dose level, 3 patients will be treated. If none (0 of 3) show a DLT, dose will be escalated for the next cohort of patients.~If 2 or 3 have a DLT, then the previous dose will be considered the MTD. If 2 or 3 in cohort 1 (starting dose) experience a DLT, then the dose in -1 cohort will be used.~If 1 of 3 patients has a DLT, then an additional 3 patients will be added to that dose level.~If 1 of 6 has a DLT, then the dose will be escalated. If 2 of 6 have a DLT, then this dose will be considered the MTD. If 3 or more of 6 have a DLT, then the previous dose will be the MTD." (NCT02038010)

An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events. (NCT02144012)

Relationship Between Tumor Minimum Uptake of Copper Cu 64-DOTA-trastuzumab as Measured by PET and Patient Best Response

Relationship between patient best response to T-DM1 and measured tumor uptake of 64Cu-DOTA-trastuzumab employed a t-test with a 0.05 two-sided significance level comparing minimum uptake in responsive vs non-responsive patients. Tumor uptake measured as SUV defined as SUV = AC(tsc) Wb /[Dinj exp(-λ(tsc - tinj)] , where AC(tsc) is the activity concentration in the volume of interest (VOI, e. g., a tumor), Wb is the patient's body weight, Dinj is the activity injected at time tinj, and λ is the decay constant for the injected radioisotope. AC(tsc) is determined from the spatial density of counts acquired from the VOI. Tumor uptake was measured in terms of minimum voxel standardized uptake value, SUVmin. Response assessment adhered to Positron Emission Tomography (PET) Response Criteria in Solid Tumors (PERCIST 1.0). (NCT02226276)

Number of Participants Achieving at Least a 15% (≥ 15-Point) Absolute Improvement From Baseline on the EORTC QLQ-OV28 Abdominal/Gastrointestinal (AB/GI) Symptom Subscale at Week 8/9 Assessment

European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Ovarian Cancer 28 (EORTC QLQ-OV28) is a 28-item ovarian cancer supplemental module. It comprises of 6 symptom scales (AB/GI symptoms, peripheral neuropathy, other chemotherapy side-effects, hormonal symptoms, body image, attitude to disease, treatment), and sexual functioning. Participants were asked to indicate extent to which they experienced AB/GI symptoms. Participants responded on a scale of 1-4(1=not at all, 2=a little, 3=quite a bit, 4=very much) to following: Did you have abdominal pain? Did you have a bloated feeling in your abdomen? Did you have problems with your clothes feeling too tight? Did you experience any change in bowel habit as a result of your disease or treatment? Were you troubled by passing wind/gas/flatulence? Have you felt full too quickly after beginning to eat? Have you had indigestion/heartburn? Data were transformed to a scale from 0-100. Lower scores=better health. (NCT02631876)

Progression-Free Survival (PFS)

PFS was the time from inclusion in the study to the date of first documented PD or death from any cause, whichever occurred first. Participants without event were censored at the date of the last tumor assessment where non-progression was documented. If a participant received a second anti-cancer therapy without prior documentation of disease progression, the participant was censored at the date of last tumor assessment before starting new chemotherapy. PD was defined as at least a 20% increase in the sum of longest diameter (LD) of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of 1 or more new lesions.

Tumor response for patients with measurable lesions should be assessed using RECIST 1.1 (Eisenhauer 2009, 0). Patients with measurable lesions should be assessed using CT or MRI scan approximately every second cycle, from the date of first dose until the 30-day Follow-up visit. Although progression may be determined by the investigator based upon clinical deterioration, every effort should be made to document progression using radiographic methods. The basis for determination of progression per clinical deterioration should be documented. (NCT03106077)

Mean Changes From Baseline in Global Health Status

EORTC QLQ-C30 is a self-reported questionnaire that included functional scales (physical, role, cognitive, emotional, social), symptom scales (fatigue, pain, nausea/vomiting), GHS/QOL and single items (dyspnea, appetite loss, insomnia, constipation, diarrhea, financial difficulties). Questions 1-28 on the QLQ-C30 were on a 4-point scale (1=Not at All to 4=Very Much). Questions 29-30 (GHS scale) were on a 7-point scale (1=Very Poor to 7=Excellent). For this instrument, GHS/QOL and functional scales were linearly transformed so each score ranged 0-100, where lower scores indicate poorer functioning (e.g., worsening) and higher scores indicate better functioning (e.g., improvement).

Participants were considered to be treatment-emergent ADA-positive if they were ADA-negative or had missing data at baseline but developed an ADA response following study drug exposure (treatment-induced ADA response), or if they were ADA-positive at baseline and the titer of one or more post-baseline samples was at least 0.60 titer units greater than the titer of the baseline sample (treatment-enhanced ADA response). Participants were considered to be treatment-emergent ADA-negative if they were ADA-negative or were missing data at baseline and all post-baseline samples were negative, or if they were ADA-positive at baseline but did not have any post-baseline samples with a titer that was at least 0.60 titer units greater than the titer of the baseline sample (treatment unaffected). (NCT03726879)
Timeframe: Day 1 Cycle (C) 1, 8, 12 and at treatment discontinuation visit (ATDV) (an average of 1 year). C 1-4, each C is 14 days. C 8-12, each C is 21 days. With protocol version 5, collection is only required ATDV/completion (an average of 1 year).

Mean Changes From Baseline in Global Health Status

EORTC QLQ-C30 is a self-reported questionnaire that included functional scales (physical, role, cognitive, emotional, social), symptom scales (fatigue, pain, nausea/vomiting), GHS/QOL and single items (dyspnea, appetite loss, insomnia, constipation, diarrhea, financial difficulties). Questions 1-28 on the QLQ-C30 were on a 4-point scale (1=Not at All to 4=Very Much). Questions 29-30 (GHS scale) were on a 7-point scale (1=Very Poor to 7=Excellent). For this instrument, GHS/QOL and functional scales were linearly transformed so each score ranged 0-100, where lower scores indicate poorer functioning (e.g., worsening) and higher scores indicate better functioning (e.g., improvement). (NCT03726879)
Timeframe: Baseline; Day 1 of Cycle 1-9, on Day 1 of every other cycle thereafter until Cycle 22; at the treatment discontinuation or early termination visit and follow up visit. Cycle 1-4, each cycle is 14 days. Cycle 5-22, each cycle is 21 days.
