  • Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment
  • Male sterilization (at least 6 months prior to screening). For female patients on the study, the vasectomized male partner should be the sole partner for that patient
  • Combination of the two following
  • Placement of an intrauterine device (IUD) or intrauterine system (IUS)
  • Barrier methods of contraception: Condom or Occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/ vaginal suppository.
  • Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential.
  • Sexually active males unless they use a condom during intercourse while taking the drug and for 4 months after stopping treatment and should not father a child in this period. A condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid.

About this study

Participants that have breast cancer that has spread to other parts of the body, is positive for a protein called HER2, and has not responded to standard treatment. This research study is a way of gaining new knowledge about the combination of Ribociclib with other drugs as a possible treatment for this diagnosis.

Read the detailed description

This research study is a Phase Ib/II clinical trial, which tests the safety of an investigational intervention and also tries to define the appropriate dose of the investigational intervention to use for further studies.

Ribociclib is a drug that is designed to block certain proteins called Cyclin-Dependent Kinases (CDKs) that are required for cells to divide. These proteins may also control the ability of certain cancers to grow.

In this research study, there will be 3 separate cohorts that are looking for the safe and tolerated dose of ribociclib that can be given in combination with other HER2 directed therapy. One cohort will be looking at the safety of ribociclib in combination with trastuzumab emtansine (T-DM1). T-DM1 is a standard treatment for patients with HER2-positive breast cancer. One Cohort will be looking at the safety of ribociclib in combination with trastuzumab (Herceptin), which is a standard treatment for patients with HER2-positive breast cancer. The last cohort will be looking at the safety of ribociclib in combination with trastuzumab (Herceptin) and fulvestrant (Faslodex) for ER-positive and HER2-positive breast cancer. These are both standard treatments for this type of breast cancer.

The FDA (the U.S. Food and Drug Administration) has not approved Ribociclib as a treatment for any disease.

What is being measured

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

  1. Cohort A: Recommended Phase2 Dose (RP2D)

    Standard 3+3 phase-I design will be utilized in this trial. Briefly, a minimum of 3 evaluable patients will be entered at first dose level (=300 mg ribociclib) and T-DM1 (3.6 mg/kg IV). If 1 out of the first 3 patients enrolled experiences a dose-limiting toxicity (DLT), 3 additional patients will be enrolled to that dose level. If no more than 1 patient in 6 experiences a DLT, dose escalation of ribociclib will continue to next dose-level. If 2 or more patients at any given dose level experience a DLT, dose escalation will stop and the Recommended Phase2 Dose (RP2D) will be defined. Maximum dose-escalation of Ribociclib (LEE011) will be up to 600 mg.

    Measured: Disease was evaluated at baseline and each cycle on treatment and the end of treatment. Toxicity was evaluated each cycle on treatment, end of treatment and 30 days follow-up. Median treatment duration was 10.9 months with range 2.5 - 19.3 months.

  2. Cohort B: Clinical Benefit Rate (CBR)

    CBR is defined as the proportion of patients with a complete response (CR) or partial response (PR), or with stable disease (SD) at week 24 by RECIST 1.1 criteria. CBR will be reported with 90% confidence interval, adjusting for two-stage design using the method from Atkinson and Brown.

    Measured: at week 12

  3. Cohort C: Clinical Benefit Rate (CBR)

    CBR is defined as the proportion of patients with a complete response (CR) or partial response (PR), or with stable disease (SD) at week 24 by RECIST 1.1 criteria. CBR will be reported with 90% confidence interval, adjusting for two-stage design using the method from Atkinson and Brown.

    Measured: at week 12

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Ribociclib, T-DM1 and Trastuzumab in people with Breast Cancer, run by Dana-Farber Cancer Institute at 2 sites in United States.

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 35 inclusion and 45 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 1 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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 combined 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.

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?

Yes. Results are posted in the registry (first posted 3 Jun 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Cohort A: Recommended Phase2 Dose (RP2D) (time frame: Disease was evaluated at baseline and each cycle on treatment and the end of treatment. Toxicity was evaluated each cycle on treatment, end of treatment and 30 days follow-up. Median treatment duration was 10.9 months with range 2.5 - 19.3 months.). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02657343, which also lists 1 linked publication.

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 1 Aug 2022.
