PF-03084014PF-03084014PF-03084014 will be administered orally, continuously, twice daily at 150 mg, but the dose can be reduced to 100 mg or 80 mg.
Primary Outcome Measures
NameTimeMethod
Objective Response (OR) Rate in Participants With Advanced Triple Receptor-Negative Breast Cancer (mTNBC) Harboring Activating Genomic Alterations in Notch Receptors (NA+)Cycle 3 Day 1, Cycle 5 Day 1, and every 6 weeks for subsequent cycles ntil disease progression, patient refusal for further follow up, or start of another anti-cancer treatment, whichever occurred first.

OR status based on assessment of confirmed complete remission (CR) or confirmed partial remission (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST 1.1). CR: Complete disappearance of all target lesions with the exception of nodal disease and all target nodes decreased to normal size (short axis less than \[\<\]10 millimeter \[mm\]). PR: Greater than or equal to (\>=)30% decrease under baseline of the sum of diameters of all target measurable lesions. OR=CR+PR.

Secondary Outcome Measures
NameTimeMethod
Progression-Free Survival (PFS) in Participants With NA+ or NA mTNBC2 years

The period from study entry until disease progression, death, whichever occurred first as per RECIST version 1.1.

Pharmacodynamic (PD) Effects of PF-03084014 in Tumor Specimens and Peripheral BloodDay 1 of Cycle 1, 2, 3, and 5

Original diagnostic tumor tissue or the most recent metastatic tumor (archival or de novo biopsy), plasma, and peripheral blood samples were collected for biomarker assessments of circulating analytes, immunohistochemistry for notch receptors expression, expression of notch pathway components and modulators, mutational analysis of pathway and disease associated genes.

Number of Participants With Laboratory Test (Urinalysis) AbnormalitiesDay 1 of Cycle 1

Number of participants with CTCAE version 4.03 grade 1 to 4 urinalysis test abnormalities for urine protein.

Overall Survival (OS) in Participants With NA+ or NA mTNBC2 years

OS was the duration from enrollment to death. For participants who are alive, overall survival was censored at the last contact.

Pre-dose Serum Concentration (Ctrough) for PF-03084014Day 1 of Cycle 1, 2, 3, and 5
Alterations in Genes, Proteins, and RNAs Relevant to the Notch Signaling Pathway, to TNBC Biology, and to Sensitivity/Resistance to PF-03084014 in Tumor Specimens and Peripheral Blood.Day 1 of Cycle 1, 2, 3, and 5

Original diagnostic tumor tissue or the most recent metastatic tumor (archival or de novo biopsy), plasma, and peripheral blood samples were collected for biomarker assessments of circulating analytes, immunohistochemistry for notch receptors expression, expression of notch pathway components and modulators, mutational analysis of pathway and disease associated genes.

OR Rate in Participants With mTNBC Whose Tumors Tested Negative for Eenomic Alterations in Notch Receptor (NA-)Cycle 3 Day 1, Cycle 5 Day 1, and every 6 weeks for subsequent cycles ntil disease progression, patient refusal for further follow up, or start of another anti-cancer treatment, whichever occurred first.

OR status based on assessment of confirmed CR or confirmed PR according to RECIST 1.1. CR: Complete disappearance of all target lesions with the exception of nodal disease and all target nodes decreased to normal size (short axis \<10 mm). PR: \>=30% decrease under baseline of the sum of diameters of all target measurable lesions. OR=CR+PR.

Duration of Response (DR) in Participants With NA+ or NA mTNBC2 years

Time from the first documentation of objective tumor response to objective tumor progression or death due to any cause. DR was calculated for the subgroup of patients with a confirmed objective tumor response. Objective Progression (PD): 20% increase in the sum of diameters of target measurable lesions above the smallest sum observed (over baseline if no decrease in the sum is observed during therapy), with a minimum absolute increase of 5 mm.

One-Year Survival Probability in Participants With NA+ or NA mTNBC1 year

Overall survival (OS) status (alive or not) at 1 year after study entry. The the survival probability at 1 year was summarized as a product limit estimator based on the Kaplan-Meier method to account for censored events.

Type of Notch Genomic Alterations in Participants With NA+ mTNBC2 years

Type of notch genomic alterations identified by NGS assay in patients with NA+ mTNBC

Number of Notch Genomic Alterations in Participants With NA+ mTNBC2 years

Number of notch genomic alterations identified by NGS assay in patients with NA+ mTNBC

Number of Participants With Treatment-Emergent Adverse Events (AEs) or Serious Adverse Events (SAEs)2 years

An AE was any untoward medical occurrence without regard to causality in a participant who received study drug. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent AEs were defined as all deaths, regardless of cause, from treatment start until 28 days after the last dose and non-fatal events occurring after treatment start regardless of cause, up until 28 days after the last dose or until start of new anti-cancer treatment, whichever was first.

Number of Participants With Treatment-Emergent AEs by CTCAE Grade2 years

An AE was any untoward medical occurrence without regard to causality in a participant who received study drug. AEs were defined according to Common Terminology Criteria for Adverse Events (CTCAE) version 4.03.

Number of Participants With Laboratory Test (Hematology) AbnormalitiesDay 1 of Cycles 1, 2, 3, 4, 5, and subsequent cycles.

Number of participants with CTCAE version 4.03 grade 1 to 4 hematological test abnormalities.

Number of Participants With Laboratory Test (Chemistry) AbnormalitiesDay 1 and Day 15 of Cycles 1, 2, 3, 4, 5, and subsequent cycles up to Cycle 8 and Day 8 of Cycle 1

Number of participants with CTCAE version 4.03 grade 1 to 4 chemistry test abnormalities
