BKM120 For Triple Negative Breast Cancer

January 17, 2019 updated by: Nancy Lin, MD, Dana-Farber Cancer Institute

A Phase II Trial of BKM120 in Patients With Triple Negative Metastatic Breast Cancer

Triple negative breast cancer (TNBC) has an aggressive phenotype and poor prognosis. This tumor type characterized by lack of expression of estrogen receptor (ER), progesterone receptor (PR) and no amplification of the human epidermal growth factor 2 (HER2) accounts for 15% of breast cancers. Limited treatment options exist in the clinic as hormonal therapies and HER2-trageted agents have proven ineffective. BKM120 is a drug that works by blocking a protein called phosphatidylinositol-3-kinase (PI3K) which may contribute to cancer growth. This drug has been used in experiments in the laboratory and information from these research studies suggests that BKM120 may help to prevent cancer cells from growing. In this research study, the investigators are looking to see if BKM120 works to stop breast cancer cells from growing.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Study plan Two investigator-initiated protocols (one for US, one for Spain) will be enrolling in parallel. The first 50 participants will be recruited concurrently in US and Spain.

Stage 1 Stage 1 will include up to 50 participants with advanced TN disease. Available tumor block is required in all participants per inclusion criteria. Analysis of this tumor block will be used for correlation of predictive markers and clinical response in order to define potential subpopulation that benefit from BKM120. In Stage 1, all participants will have biopsies done at baseline, cycle 1 day 28/cycle 2 day 1 and end of treatment to analyze drug effect in the PI3K and mitogen-activated protein kinases (MAPK) pathway. This will aid to understand the pharmacodynamic effects of BKM120 in tumors with similar genetic background (triple negative disease). The enrollment of Stage 1 will ensure that at least 10 paired evaluable biopsies are obtained. After the enrollment of the first 29 evaluable subjects enrolled overall in Stage 1 (considering the US and the Spanish protocol), the Steering Committee will perform an interim analysis of safety and efficacy. If absolutely no activity is observed, the clinical trial will close and no more subjects will be enrolled. If there are early signs of activity (one patient or more achieving clinical benefit response), enrollment will proceed until 50 participants are enrolled in Stage 1. After 50 patients have been enrolled, we will analyze preliminary responses to treatment depending on the molecular status of each patient.

Stage 2 Were the trial to continue at the end of Stage 1, 50 participants would have been treated and their clinical status and response to therapy will be available. Also, paraffin blocks from these participants will have been analyzed for predictive markers of treatment effect. If there is clinical activity observed in Stage 1 and this analysis shows preliminary signs of response in a subpopulation based on the presence or absence of tumor PI3K pathway alterations, participant pre-selection may be implemented for Stage 2 (justified in an amendment before proceeding to Stage 2.

Phase

Phase

The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Clinical Benefit Rate
Time Frame: Disease was evaluated radiologically at baseline and every 2 cycles on treatment then every 3 months up to 2 years. Participants in this study cohort were followed for response on average approximately 2 months.
Clinical benefit rate (CBR) was defined as the proportion of participants achieving complete response (CR), partial response (PR), or stable disease (SD) for 4 months or longer based on RECIST 1.1 criteria on treatment. Per RECIST 1.1 for target lesions: CR is complete disappearance of all target lesions and PR is at least a 30% decrease in the sum of longest diameter (LD) of target lesions, taking as reference baseline sum LD. PD is at least a 20% increase in sum LD of target lesions (smallest sum LD reference), new lesions, and/or unequivocal progression of existing non-target lesions. Stable disease (SD) is defined as any condition not meeting the above criteria.
Disease was evaluated radiologically at baseline and every 2 cycles on treatment then every 3 months up to 2 years. Participants in this study cohort were followed for response on average approximately 2 months.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Progression Free Survival
Time Frame: Disease was evaluated radiologically at baseline and every 2 cycles on treatment then every 3 months up to 2 years. Participants in this study cohort were followed for PFS on average approximately 2 months.
Progression-free survival (PFS) based on the Kaplan-Meier (KM) method is defined as the duration of time from study entry to documented disease progression (PD) or death. Participants alive without PD are censored at the date of last disease assessment. Per RECIST 1.1 criteria: PD is 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 one or more new lesions. 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.
Disease was evaluated radiologically at baseline and every 2 cycles on treatment then every 3 months up to 2 years. Participants in this study cohort were followed for PFS on average approximately 2 months.
Overall Survival
Time Frame: Participants were assessed every 3 months post-treatment up to 2 years. Average survival follow-up for the study cohort was 13.8 months.
Overall survival (OS) is defined as the duration of time from study entry to death or date last known alive and estimated using the KM method.
Participants were assessed every 3 months post-treatment up to 2 years. Average survival follow-up for the study cohort was 13.8 months.
