What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of dose-limiting toxicities (DLTs)

    Dose Escalation Phase: Frequency of DLTs at each dose level associated with administration of LEE011, buparlisib, and letrozole in a 28 day cycle

    Measured: 28 days

  2. Safety and tolerability of the combination of LEE011, buparlisib, and letrozole

    Dose Expansion Phase: Incidence of AEs, SAEs (overal and severity), laboratory abnormalities, ECG, vital, dose interteruptions, dose reductions, and dose intensity as a measure of safety and tolerability.

    Measured: approximately 25 months

Secondary outcomes (5)
  1. Safety and tolerabiity of the combination of LEE011, buparlisib, and letrozole

    Dose Escalation Phase: Incidence of AEs, SAEs (overall and severity), laboratory abnormalities, ECG, vital, dose interterruptions, dose reductions, and dose intensity as a measure of safety and tolerability.

    Measured: approximately 25 months

  2. Pharmacokinetic paramters such as AUClast and Cmax of LEE011, buparlisib, and letrozole in order to characterize the PK profiles

    Dose Escalation Phase: When given in combination as well any other clinically significant metabolites that may be identified

    Measured: approximately 25 months

  3. Pharmacokinetic paramters such as AUClast and Cmax of LEE011, buparlisib, and letrozole in order to characterize the PK profiles

    Dose Expansion Phase: When given in combination as well as any other clinically significant metabolites that may be identified

    Measured: approximately 25 months

  4. Disease control rate

    Dose Expansion Phase: Proportion of patients with the best overall response of CR (complete response), PR (partial response), or SD (stable disease)

    Measured: approximately 25 months

  5. PFS (progression free survival)

    Dose Expansion Phase: Time from date of start of treatment to date of first documented progression or death due to any cause.

    Measured: approximately 25 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing LEE011, Buparlisib and Letrozole in people with Advanced or Metastatic Breast Cancer, run by Novartis Pharmaceuticals at 6 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Dec 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States, Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of dose-limiting toxicities (DLTs) (time frame: 28 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Dec 2020.
