About this study

This study is to learn if the combination therapy of capmatinib and neritinib can help to control metastatic or locally advanced breast cancer. Researchers also want to find the highest tolerable dose of the combination therapy of capmatinib and neritinib that can be used in this study drug combinations. The safety of this drug combination and the CELsignia MP test methodology will also be studied.

Read the detailed description

This is an open-label, phase Ib/II study of neratinib plus Capmatinib in patients with metastatic breast cancer and patients with metastatic IBC.

Phase 1b - Dose Escalation of Neratinib with Capmatinib

This phase of the study will employ the Bayesian optimal interval (BOIN) design with the 3+3 design run-in, to find the MTD. The BOIN design is implemented in a simple way similar to the traditional 3+3 design, but is more flexible and possesses superior operating characteristics that are comparable to those of the more complex model-based designs, such as the continual reassessment method (CRM). The maximum sample size for dose escalation is 18. Patients are treated in cohorts of 3, beginning with Neratinib PO dose level 1 (120 mg, Dose 1-7, 160 mg, through end of treatment, see Table 2) in combination with Capmatinib PO level 1 (400 mg, see Table 3), with a maximum of 12 patients per dose. The target toxicity rate for the maximum tolerable dose (MTD) is 25%.

Phase II

Phase II will be a prospective, open label, interventional study for patients with previously treated HER2-negative metastatic breast cancer or metastatic inflammatory breast cancer. Subjects receive Capmatinib in combination with Neratinib (including an AI for patients with ER+/HER2- breast cancer). The MTD determined during Phase 1b will be used.

This portion of the trial will be conducted to assess the overall response rate (ORR) for patients treated at the MTD. The target ORR will be 25%, with unacceptable ORR as 5%. We assess the ORR using the Bayesian optimal phase 2 (BOP2) design (Zhou, Lee and Yuan, 2017).

Up to an additional 29 evaluable subjects with measurable disease will be enrolled. An interim analysis will be performed when the number of enrolled patients reaches 15.

What is being measured

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

  1. To Determine Maximum Tolerated Dose for Use in the Phase II Portion of the Trial

    This phase of the study uses the Bayesian Optimal Interval (BOIN) design with a 3+3 run-in to identify the maximum tolerable dose (MTD). Patients are treated in cohorts of 3 with a maximum of 27 participants. Starting with Neratinib PO dose level 1 (120 mg for Dose 1-7, then 160 mg) combined with Capmatinib PO level 1 (400 mg), with up to 12 patients per dose. The target toxicity rate for the MTD is 25%.

    Measured: Cycle1 and 2, total 56 days

  2. To Determine Overall Response Rate

    The overall response rate (ORR) for patients treated at the MTD in Phase II was assessed. ORR was defined as the proportion of patients who achieved a partial response or complete response as their best response. All tumor responses were evaluated according to RECIST 1.1 criteria and measured using the QIAC system.

    Measured: Up to 3 years

Secondary outcomes (5)

  1. To Further Characterize the Safety and Tolerability of Neratinib + Capmatinib

    Adverse events (AEs) graded using CTCAE version 5.0: ≥ Grade 2 for non-hematological and ≥ Grade 3 for hematological AEs observed after the first protocol intervention for phase II patients.

    Measured: Up to 3 years

  2. To Determine Clinical Benefit Rate (CBR)

    Clinical benefit rate (CBR) is defined as the proportion of patients achieving complete response, partial response, or stable disease for ≥24 weeks, was summarized by frequency and percentage with Wilson 95% confidence intervals, overall and by dose level.

    Measured: Up to 27 months

  3. To Determine the Duration of Response (DOR)

    Duration of response (DOR) is defined as the period from the date of the first occurrence of a CR or PR until the first date that progressive disease or death is documented.

    Measured: Up to 27 months

  4. To Determine Progression Free Survival (PFS)

    PFS is defined as the time between date of treatment start to the date of documented disease progression or death, whichever occurs first

    Measured: Up to 27 months

  5. To Determine 2 Year Overall Survival (OS)

    The proportion of patients in the study who are alive 2 years after enrollment on to the study

    Measured: 2 years after enrollment

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Neratinib and Capmatinib in people with Metastatic Breast Cancer and Breast Cancer, run by M.D. Anderson Cancer Center at 1 site 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 33 inclusion and 46 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: stopped early, as of the sponsor's last update on 11 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 15 May 2025). 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?

To Determine Maximum Tolerated Dose for Use in the Phase II Portion of the Trial (time frame: Cycle1 and 2, total 56 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?

On the ClinicalTrials.gov record for NCT05243641.

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 11 Jun 2025.
