About this study

Official title: A Randomized Double-Blind Phase-2 Study of Anastrozole Plus Lonafarnib (SCH 66336) or Anastrozole Plus Placebo for the Treatment of Subjects With Advanced Breast Cancer

Primary Objective(s):

  • To compare the activity (progression-free survival [PFS]) of anastrozole in combination with lonafarnib to that of anastrozole in combination with placebo in subjects with hormone-sensitive ADVANCED breast cancer.

Secondary Objective(s):

  • To determine the effects of anastrozole in combination with lonafarnib on objective response, duration of response, overall survival, and safety in subjects with advanced breast cancer. To assess the exposure and pharmacokinetics of lonafarnib and anastrozole in the subject population.

Study groups in NCT00081510
Study groupRoleWhat they receive
Lonafarnib plus AnastrozoleExperimentalParticipants receive lonafarnib 200 mg orally (PO) twice per day (BID) beginning on Day 1 Cycle 1 and continuing until Progression of Disease, unacceptable toxicity, or other discontinuation criteria are met; and anastrozole 1 mg, PO, once per day (QD) for as long as the participant is receiving lonafarnib
Receives: Drug: Lonafarnib; Drug: anastrozole
Placebo plus AnastrozoleActive comparatorParticipants receive placebo to lonafarnib PO BID beginning on Day 1 Cycle 1 until Progression of Disease, unacceptable toxicity, or other discontinuation criteria are met; and anastrozole, 1mg PO QD for as long as the participant is receiving placebo
Receives: Drug: Placebo; Drug: anastrozole

What is being measured

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

  1. Progression-free survival (PFS)

    Measured: When approximately 70 subjects have progressed

Secondary outcomes (2)
  1. Objective response rate (adjusted RECIST criteria), duration of response, and overall survival

    Measured: When approximately 70 subjects have progressed

  2. To access the exposure and pk of lonafarnib and anastrazole in the subject population.

    Measured: When approximately 70 subjects have progressed

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Lonafarnib and anastrozole in people with Breast Cancer, run by Merck Sharp & Dohme LLC.

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 10 inclusion and 4 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 15 Apr 2015. Status can change between updates, so confirm with the study contact before making plans.

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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Progression-free survival (PFS) (time frame: When approximately 70 subjects have progressed). 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 15 Apr 2015.
