Overview

PUMA-ALI-1201 is a randomized, dose optimization, multicenter, Phase 2 study of alisertib administered in combination with endocrine therapy in participants with pathology-confirmed HR-positive/HER2-negative metastatic breast cancer (MBC) following progression on or after at least two prior lines of endocrine therapy in the recurrent or metastatic setting. This study is intended to evaluate the optimal alisertib dose administered in combination with the selected endocrine therapy. The study is also planned to evaluate the efficacy, safety, and pharmacokinetics of alisertib in combination with endocrine and to identify the biomarker-defined subgroup(s) that may benefit most from combined alisertib and endocrine therapy.

Description

There will be no screening period for this study. After completion of the appropriate consent process, eligible participants can start treatment with remibrutinib as soon as they enter the study. All participants must visit the study site for their enrollment visit to confirm eligibility and commence study participation. Participants will return to the study center at least every 16 weeks for resupply of study medication but may return earlier if needed.

Participants will receive remibrutinib at the dose and regimen they last received in the parent study.

Participants will continue to receive remibrutinib for up to 3 years or until one of the following occurs: no treatment benefit, participant wishes to discontinue trial participation or withdraws consent, protocol non-compliance, pregnancy, the investigator feels it is no longer in the participant's best interest to continue therapy, or the participant receives access to treatment with remibrutinib outside of a clinical study, whichever occurs first.

Eligibility

Inclusion Criteria:

\- Participant has completed treatment per protocol in a Novartis study of remibrutinib (unless otherwise specified in a parent study protocol) in a dermatological or allergology indication.

Participants, who derive benefit from the treatment with remibrutinib but have not completed the treatment in certain parent studies due to parent study termination by Novartis, may be eligible if the termination was due to reasons other than safety or lack of efficacy (e.g., technical / administrative reasons).

  • Participant is deriving benefit from remibrutinib, investigator believes he/she would continue to derive benefit from remibrutinib and the benefit outweighs the risk, based on the investigator's judgement.
  • Participant is unable to obtain access to the marketed remibrutinib formulation per local post study drug supply program, prescription and/or reimbursement guidelines.

Exclusion Criteria:

Participants meeting any of the following criteria are not eligible for inclusion in this study.

  • Participant has prematurely discontinued study treatment in the parent study.
  • Use of prohibited medications

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
