Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Overall Response (Partial Response + Complete Response) for Participants With Triple Negative Breast Cancer (TNBC) | From start of treatment until disease progression/recurrence, approximately 5 months and 17 days. | Overall response is defined as the best response (Partial Response + Complete Response) recorded from the start of treatment until disease progression/recurrence assessed by the Response Evaluation Criteria in Solid Tumors (RECIST)v1.1. Complete response is disappearance of all target lesions. Partial response is at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum of diameters. Progression is at least a 20% increase in the sum of diameters of target lesions. appearance of new lesions. Appearance of one or more new lesions. |
| Primary | Overall Response (Partial Response + Complete Response) for Participants With Human Epidermal Growth Factor Receptor 2 (HER2) + Breast Cancer (BC) | From start of treatment until disease progression/recurrence, approximately 5 months and 17 days. | Overall response is defined as the best response (Partial Response + Complete Response) recorded from the start of treatment until disease progression/recurrence. Response was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST)v1.1. Complete response is disappearance of all target lesions. Partial response is at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum of diameters. Progression is at least a 20% increase in the sum of diameters of target lesions. appearance of new lesions. Appearance of one or more new lesions. |
| Primary | Number of Participants Experiencing at Least One Grade 3 to 5 Adverse Events for Each of the Three Combinations of Agents | Date treatment consent signed to date off study, approximately 5 months and 17 days. | Adverse events were recorded using the Common Terminology Criteria for Adverse Events (CTCAE) v5.0. Grade 3 is severe, Grade 4 is life-threatening, and Grade 5 is death related to adverse event. |
| Secondary | Progression-free Survival (PFS) in Triple Negative Breast Cancer (TNBC) | From start of treatment to time of progression or death, whichever occurs first, approximately 5 months and 17 days. | Progression free survival is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first. In the absence of progression or death, PFS is censored at the date of last disease evaluation. Progression was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST)v1.1 and is defined as at least a 20% increase in the sum of diameters of target lesions. appearance of new lesions. Appearance of one or more new lesions. |
| Secondary | Progression Free Survival (PFS) in Participants With Metastatic Hormone Receptor (HR)-/Human Epidermal Growth Factor Receptor 2 (HER2) + Metastatic Breast Cancer Who Progressed on Initial Treatment With THP | From start of treatment to time of progression or death, whichever occurs first, approximately 5 months and 17 days. | Progression free survival is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first. In the absence of progression or death, PFS is censored at the date of last disease evaluation. Progression was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST)v1.1 and is defined as at least a 20% increase in the sum of diameters of target lesions. appearance of new lesions. Appearance of one or more new lesions. |
| Secondary | Progression Free Survival (PFS) in Participants With Metastatic Human Epidermal Growth Factor Receptor 2 (HER2+) Metastatic Breast Cancer Who Progressed on Initial Treatment With Docetaxel (THP) | From start of treatment to time of progression or death, whichever occurs first, approximately 5 months and 17 days. | Progression free survival is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first. In the absence of progression or death, PFS is censored at the date of last disease evaluation. Progression was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST)v1.1 and is defined as at least a 20% increase in the sum of diameters of target lesions. appearance of new lesions. Appearance of one or more new lesions. |
| Secondary | Absolute Percentage of Stromal Tumor Infiltrating Lymphocytes (TILs) in Metastatic Deposits in Participants With Metastatic Human Epidermal Growth Factor Receptor 2 (HER2+) Metastatic Breast Cancer | Baseline and on Cycle 3 Day 1 | The absolute percentage of stromal TILs was measured by the Salgado method in metastatic deposits in participants with metastatic HER2+ metastatic breast cancer. The Salgado method is a standardized approach for measuring the percentage of stromal TILs in primary breast tumor specimens before therapy, using visual assessment of standard hematoxylin and eosin (H\&E)-stained sections. |
| Other | Number of Participants With Serious and Non-serious Adverse Events Assessed by the Common Terminology Criteria for Adverse Events (CTCAE v5.0) | Date treatment consent signed to date off study, approximately 5 months and 17 days. | Here is the number of participants with serious and non-serious adverse events assessed by the Common Terminology Criteria for Adverse Events (CTCAE v5.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned. |
