  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Patients must have histologically or cytologically confirmed diagnosis of HER2+ breast cancer. Patients may be immunohistochemistry (IHC) 3+ and/or fluorescence in situ hybridization (FISH) positive for HER2. IHC 2+ HER2 patients are eligible with reflex FISH-positive testing with the ratio ≥ 2.0. Alternatively, circulating tumor DNA testing positive for HER2 mutation is accepted for eligibility
  • Patients must have newly diagnosed or progressive brain and/or leptomeningeal metastases, and a change in management and of treatment regimen is indicated. There is no limit on the number and types of prior systemic or intrathecal therapies
  • Subjects must have an estimated life expectancy ≥ 3 months
  • At registration, patients must have an interval of at least 2 weeks after the end of prior cytotoxic chemotherapy or immunotherapy or previous RT, one week from prior targeted small molecule drug treatment, interval of ≥ 4 weeks from prior bevacizumab or nitrosourea. At treatment start of trotabresib, there must be an interval of ≥ 4 weeks since last cytotoxic chemotherapy (6 weeks for prior nitrosourea) or immunotherapy
  • Note: Anti-HER2 directed treatment is allowed to continue, however, should be switched to trastuzumab before initiation of trotabresib. No washout period is required
  • Patients must be age ≥ 18 years on the day of signing consent
Show all 43Show fewer
  • Patients must exhibit Cooperative Oncology Group (ECOG) performance status of ≤ 2
  • Leukocytes (WBC) ≥ 3,000/mcL or absolute neutrophil count (ANC) ≥ 1,500/mcL (within 14 days prior to registration)
  • Hemoglobin (Hgb) ≥ 10 g/dL (within 14 days prior to registration)
  • Platelets (PLT) ≥ 75,000/mcL (within 14 days prior to registration)
  • Total bilirubin < 1.5 x upper limit of normal (ULN) (except patient with documented Gilbert's syndrome, ≤ 5 x ULN) (within 14 days prior to registration)
  • Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) < 3 x institutional ULN (within 14 days prior to registration)
  • Creatinine < 1.5x upper limit of normal (ULN) (within 14 days prior to registration)
  • Patients must be able to swallow oral medication
  • Patients must have recovered from the toxic effects of prior therapies (≤ Grade 1); however, persistent alopecia, or other toxicities not constituting a safety risk or being attributed to the tumor (e.g. neurological symptoms) based on investigator's judgement are not an exclusion criterion)
  • Patients who are currently participating in or have participated in a study of an investigational agent or device must have discontinued the use of the investigational drug or device ≥ 4 weeks from registration on this study
  • Note: COVID-19 vaccination is allowed prior to and during study treatment
  • Patients with a ventriculoperitoneal or ventriculoatrial shunt must have an on/off device in their shunt systems to be eligible for the study. Patients must be able to tolerate shunt closure for approximately 4 hours without development of clinical signs of increased intracranial pressure
  • Patients must be able and willing to undergo research blood draws
  • Patients must consent to retrieval of archival tissue or pretreatment tumor biopsy for research purposes if extra tissue is available
  • The effects of trotabresib on the developing human fetus are unknown. Vinorelbineis known to be teratogenic causing birth defects and fetal loss in animals at concentrations which are below the human therapeutic dose range. For this reason, patients of child-bearing potential, patients with sperm-producing reproductive capacity and partners with child-bearing potential of patients with sperm-producing reproductive capacity much use contraception as specified below. Additionally, pregnant patients and patients that are nursing can not participate in this study because vinorelbine has the potential for teratogenic or abortifacient effects as described above. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with vinorelbine, breastfeeding should be discontinued if the mother is treated with vinorelbine
  • A patient of childbearing potential (POCBP) is a person who: 1) has achieved menarche at some point, 2) has not undergone a hysterectomy or bilateral oophorectomy, or 3) has not been naturally postmenopausal (amenorrhea following cancer therapy or other medical condition does not rule out childbearing potential) for at least 12 consecutive months and verified by an FSH blood test at screening. FSH test should be >30 mIU/mL but FSH will be low if the subject is taking hormone replacement therapy or oral contraceptives. The requirement for FSH testing may be waived for subjects greater than 62 years of age
  • Patients of childbearing potential (POCBP) must:
  • Either commit to true abstinence from heterosexual intercourse (which must be reviewed monthly and source documented) or to use one highly effective contraceptive method. True abstinence is acceptable when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception). Highly effective contraceptive methods are combined (containing estrogen and progestogen) or progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, intravaginal, patch, or implantable); bilateral tubal ligation; intra-uterine device; intrauterine hormone-releasing system; or vasectomized partner sterilization (note that vasectomized partner is a highly effective birth control method provided that partner is the sole sexual partner of the POCBP trial participant and that the vasectomized partner has received medical assessment of the surgical success). These measures should be used from 28 days before the first dose of study medication, throughout the study, and for 7 months following the last dose of trotabresib and 6 months after the last dose of vinorelbine, whichever is longer
  • Oocyte donations and nursing are prohibited during the same time period when highly effective contraception is required. Should a patient of child bearing potential experience a change in contraception method or become pregnant or suspect they are pregnant during the time period when highly effective contraception is required, they should notify the investigator immediately
  • Patients of child-bearing potential must have two negative serum or urine pregnancy tests (beta-subunit of human chorionic gonadotropin or beta-human chorionic gonadotropin [hCG]) as verified by the investigator prior to starting the study drugs. The second test should be performed on Day -1 or Day 1 prior to dosing. The pregnancy test (serum or urine) should have a sensitivity of at least 25 mIU/ml. Patients of child-bearing potential must agree to ongoing pregnancy testing monthly during dosing and for the same time period when highly effective contraception is required
  • Patients with sperm-producing capacity must agree to contraception use as indicated below:
  • Patient with sperm-producing capacity condom use
  • Patients with sperm-producing capacity must practice true abstinence (which must be reviewed on a monthly basis) or agree to use a condom (a latex or non-latex synthetic condom is required) during any sexual activity (eg, vaginal, anal, oral) with a pregnant or nursing person or a person of child-bearing potential and will avoid conceiving from signing the informed consent form, while participating in the study, during dose interruptions, and for at least 4 months after the last dose of trotabresib or 6 months after the last dose of VNB, whichever is longer, even if they have undergone a successful vasectomy. Patients with sperm-producing capacity should inform the investigator immediately if they believes that their partner has become pregnant
  • Patients with sperm-producing capacity should not donate sperm for the same period of time that is required for condom use. Partners who are of child-bearing potential must use one highly effective form of contraception during the same time period that the patients with sperm-producing capacity must use a condom
  • Patients must have the ability to understand and the willingness to sign a written informed consent document. Consent must be signed prior to registration on this study
  • Cohort S only: Patient must be a candidate for a planned surgical resection of at least one central nervous system (CNS) metastasis, with an indication for surgical resection (e.g. mass effect, therapeutic intent in oligometastatic disease, diagnostic confirmation/determination of histologic and/or molecular tumor characteristics)
  • Phase I/Ib only: Patients must have evaluable metastatic disease in the CNS and/or evidence of leptomeningeal disease (LMD) (clinically, on imaging or detected by circulating tumor cells)
  • Phase I/Ib only: Patients must have unequivocal evidence of new and/or progressive brain metastases, and at least one of the following scenarios:
  • Prior treatment with Stereotactic radiosurgery (SRS ) or surgery, and residual surgically or radiosurgically un-treated lesions remaining. Such participants are eligible for immediate enrollment on this study providing that at least one untreated lesion is evaluable or measurable
  • Patients who have not previously been treated with cranial irradiation are eligible to enter the study
  • Patients are eligible independent of presence or absence of progressive systemic disease
  • Phase I/Ib only: Patients must have an indication for local CNS-directed therapy, e.g. new metastases amenanble for radiotherapy or SRS, reduction of mass effect and/or palliation of symptoms
  • Phase I/Ib only: Patients planned radiotherapy needs to be prescribed in accordance to generally acceptable guidelines and practice, i.e.:
  • Patients who have received prior whole brain radiotherapy should only be treated with stereotactic radiosurgery (SRS)
  • A delay of ≥ 3 months should be observed between prior whole-brain radiotherapy (WBRT) and SRS
  • Repeat SRS to a lesion previously treated with SRS is not allowed
  • There is no limit to the number of lesions that have previously bee treated with SRS, and there is no limit to the number of lesions to be treated with SRS, if clinically indicated

Who cannot join

  • Patients who are on escalating doses of corticosteroids
  • Note: Patients must be on a stable or decreasing dose of corticosteroids equivalent to dexamethasone ≤ 8mg averaged over the last 7 days to be eligible for the study

About this study

Official title: A Phase I/Ib Trial of Trotabresib (BMS-986378), an Oral BET Inhibitor) in Combination With Vinorelbine and Radiation Therapy in HER2+ Breast Cancer Patients With Central Nervous System Metastasis and Leptomeningeal Disease (CA076-1008)

This phase I/Ib trial tests the safety, side effects, and best dose of vinorelbine when given in combination with trotabresib in treating patients with HER2 positive breast cancer that has spread to the central nervous system or leptomeninges (metastasis). Cancer cells that make too much HER2 may grow more quickly and are more likely to spread to other parts of the body as metastases, including the central nervous system. Trotabresib is part of a family of drugs called BET inhibitors. Trotabresib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Vinorelbine is in a class of medications called vinca alkaloids. It works by slowing or stopping the growth of cancer cells in your body. Giving trotabresib and vinorelbine may increase in the anti-cancer activity of vinorelbine when used in combination with radiation (radiotherapy).

Read the detailed description

PRIMARY OBJECTIVE:

  1. To determine the maximum tolerated dose (MTD) and recommended Phase II dose of trotabresib in combination with vinorelbine (VNR). (Phase I) II. To measure the progression free survival (PFS) from the date of first treatment of trotabresib to the date of first observation of progressive disease in both intracranial and extracranial sites in patients with brain metastases (BMs) and/or leptomeningeal disease (LMD). (Phase Ib [Expansion])

SECONDARY OBJECTIVES:

  1. To establish the safety of trotabresib in combination with VNR, measured by the number of patients with adverse events. (Phase I) II. To assess the tolerance and toxicity profile of trotabresib in combination with VNR following RT in HER2+ breast cancer patients with central nervous system (CNS) metastasis. (Phase Ib [Expansion]) II. To measure the overall survival (OS) from the date of first treatment to the date of death from any cause. (Phase Ib [Expansion]) III. To evaluate the response rate (RECIST v. 1.1 and RANO-BM criteria) in patients with measurable disease. (Phase Ib [Expansion])

EXPLORATORY OBJECTIVES:

  1. Disease monitoring using circulating tumor cells (CTCs) and circulating tumor DNA in peripheral blood and CSF. (Phase 1/1b) II. Expression of MZF1 and beta III tubulin in tumor tissue at baseline and during/after treatment when available. (Phase 1/1b) III. Evaluation of treatment response by metabolic positron emission tomography (PET) imaging using a novel 68Ga-HER2-nanobody (separate imaging protocol for select patients, pending future amendment to this trial for enrollment. (Phase 1/1b) IV. To estimate the concentrations of vinorelbine and trotabresib in central nervous system tissue (both in enhancing and non-enhancing parts). (Cohort S)

OUTLINE: This is a phase I dose-escalation study of vinorelbine followed by a phase Ib dose expansion study. Patients are assigned to 1 of 2 cohorts.

COHORT I: Patients central nervous system (CNS) metastases or leptomeningeal disease (LMD) undergo radiation therapy over 7 days in the absence of disease progression or unacceptable toxicity. Patients then receive trotabresib orally (PO) once daily (QD) on days 1-4 and vinorelbine intravenously (IV) over 6-10 minutes on days 4, 11, and 18 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo magnetic resonance imaging (MRI), computed tomography (CT), and collection of blood samples throughout the trial.

COHORT S (PRE-SURGICAL COHORT): Patients who undergo tumor resection receive trotabresib PO QD on days 1-4 and vinorelbine IV on day 4. Patients then undergo standard of care surgery. Patients may undergo radiation therapy after surgery per standard of care. Patients may then receive trotabresib PO QD on days 1-4 and vinorelbine IV over 6-10 minutes on days 4, 11, and 18 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo MRI, CT, and collection of blood samples throughout the trial.

After completion of study treatment, patients are followed up every 6 months for up to 1 year.

What is being measured

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

  1. Dose limiting toxicities (Phase I)

    Measured: Up to 28 days after treatment

  2. Incidence of adverse events (Phase Ib)

    To assess the toxicity profile of vinorelbine and trotabresib this endpoint will collect and report the frequency of adverse events by type, severity (grade), timing, and attribution to vinorelbine and trotabresib, according the National Cancer Institute (NCI)-Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. Toxicities will be summarized by maximum grade and patients with and without leptomeningeal spread will be evaluated separately.

    Measured: Up to 30 days after last dose

Secondary outcomes (4)

  1. Incidence of adverse events (Phase I)

    To assess the toxicity profile of VNR and trotabresib this endpoint will collect and report the frequency of adverse events by type, severity (grade), timing, and attribution to VNR and trotabresib, according the NCI-CTCAE version 5.0. Toxicities will be summarized by maximum grade.

    Measured: Up to 30 days after last dose

  2. Progression-free survival (PFS) (Phase Ib)

    Median PFS will be calculated based on the Kaplan-Meier estimates of PFS. PFS data will be collected from the initiation of trial therapy (C1D1) until the patient experiences disease progression, initiates subsequent anti-cancer therapy, completes study participation, or experiences death from any cause (whichever is sooner). If disease progression or death from any cause is not observed prior to initiating subsequent anti-cancer therapy or completing study participation, the PFS will be censored as the last available disease assessment.

    Measured: Time that elapses between the initiation of trial therapy (cycle 1 day 1 [C1D1]) and the day of first documented disease progression or death from any cause for all evaluable patients, assessed up to 1 year

  3. Overall survival (OS) (Phase Ib)

    Medium OS (mOS) will be calculated based on the Kaplan-Meier estimates of OS. OS data will be collected from the initiation of trial therapy (C1D1) until the patient completes study follow up participation, experiences death from any cause or is documented as lost to follow up per institutional standard (whichever is sooner). If death from any cause is not observed prior to completing study participation, the OS will be censored as the time of the last available documentation of survival status. Last available documentation of survival status is defined as the date of death or the latest of the following times: treatment discontinuation date, last dosing administration date, last disease assessment date, or the last follow-up date when the patient was known to be alive.

    Measured: Time that elapses between the initiation of trial therapy (C1D1) and the date of death from any cause for all evaluable patients, assessed up to 1 year

  4. Objective response rate (ORR) (Phase Ib)

    will calculate the proportion of treated patients who experience an objective response [confirmed complete response (CR) or confirmed partial response (PR) per Response Evaluation Criteria in Solid Tumors (RECIST) 1.11 and Response Assessment in Neuro-Oncology Brain Metastases (RANO-BM) criteria. Confirmation of response should be conducted via imaging ≥ 28 days after the response was first documented. The date of first response for either CR or PR will be used for the calculation of ORR. ORR data will be collected from the initiation of trial therapy (C1D1) until the response has been confirmed, the patient experiences disease progression, initiates subsequent anti-cancer therapy, or completes study participation (whichever occurs first). Will also determine the objective response rate specifically for intracranial/central nervous system (CNS) disease, disease sites with and without radiotherapy, and extracranial disease.

    Measured: Time that elapses between the initiation of trial therapy (C1D1) and the date of death from any cause for all evaluable patients, assessed up to 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Biospecimen Collection, Computed Tomography and Magnetic Resonance Imaging in people with Breast Carcinoma and Metastatic Malignant Neoplasm in the Brain, run by Northwestern University 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 43 inclusion and 29 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: withdrawn, as of the sponsor's last update on 1 Apr 2024. 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 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 was withdrawn before enrolling participants, so there are no results.

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?

Dose limiting toxicities (Phase I) (time frame: Up to 28 days after treatment). 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 NCT06137651.

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 Apr 2024.
