简要总结
This is an open-label, single arm, non-randomized, multicenter, phase 2 study assessing the efficacy and safety of T-DXd as first-line treatment in HER2-positive advanced/metastatic BC patients (N=300). The study integrates digital health tools for proactive toxicity management and potentially facilitate early detection of ILD/pneumonitis.
详细描述
*Study Population*
The study will enroll male or pre/post-menopausal women aged ≥ 18 years with locally advanced or metastatic HER2-positive (IHC 3+ or ISH+, by local testing) BC who have not received prior chemotherapy or HER2-targeted therapy for advanced/metastatic disease. Eligible patients should have evaluable disease (measurable and not measurable) as defined by Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1. Patients with active and treated CNS metastases not requiring immediate local therapy are eligible.
*Study Interventions *
Patients meeting all eligibility criteria will receive T-DXd at 5.4 mg/kg administered as IV infusion q3w in combination with pertuzumab at a loading dose of 840 mg on Day 1 of Cycle 1, followed by 420 mg in subsequent cycles, administered as IV q3w. Treatment will be administered continuously until RECIST 1.1-defined progressive disease, unacceptable toxicity, investigator's decision, withdrawal of consent, or other reasons described in the protocol. T-DXd rechallenge will be allowed for patients who discontinued T-DXd for reasons other than progressive disease, grade ≥2 ILD or any toxicity requiring permanent discontinuation per T-DXd SmPC and/or protocol-defined management guidelines, and who have progressed to maintenance treatment. Standard endocrine therapy (aromatase inhibitor, fulvestrant or tamoxifen) administered concurrently with the study treatment (from C1D1) is allowed for patients with HR-positive tumors, as per local practice. For men and premenopausal women, LHRH agonist is allowed as per local practice.
Patients will be followed via digital health tools. These consist of one mobile app and two devices:

The most recent test result prior screening period will be used to confirm eligibility.
- •Documented HR (ER and/or PR) positivity or negativity, confirmed by local laboratory assessment in a tumor sample obtained in the metastatic setting. ER and/or PR positivity is defined as >1% of cells expressing HR via IHC analysis as per most recent ASCO-CAP guideline. The most recent test result prior screening period will be used to confirm eligibility.
- •No prior chemotherapy or HER2-targeted therapy for advanced or mBC (1 prior line of endocrine therapy is allowed for mBC). Participants who have received chemotherapy or HER2-targeted therapy in the neoadjuvant or adjuvant setting at any time are eligible.
- •Note: Patients that received an antibody-drug conjugate containing an exatecan derivative (topoisomerase I inhibitor) in the adjuvant setting, must have a disease-free interval of ≥12 months since the last dose.
- •Evaluable disease as defined by RECIST v1.
- •Note: Previously irradiated lesions can be considered as measurable disease only if disease progression has been unequivocally documented at that site since radiation.
- •Adequate FFPE tumor tissue sample available from the metastatic setting (preferably) for retrospective HER2 central analysis confirmed by central laboratory. An adequate sample of tumor tissue must be provided from either a newly acquired biopsy from a region that has not been previously irradiated or the most recent archival sample.
- •Patients with Brain Metastases (BM): Eligible if either previously untreated or previously treated BM, provided there is no clinical indication for immediate local therapy. For untreated BM, lesions must be ≤2.0 cm in largest diameter; lesions >2.0 cm require discussion with and approval from the Medical Monitor. Patients must not require >3 mg/day of dexamethasone (or equivalent corticosteroid) for symptom control. If receiving anticonvulsants, the regimen must be stable for ≥14 days prior to first dose. A washout period prior enrollment of ≥3 weeks since stereotactic radiosurgery or gamma knife, whole-brain radiotherapy, or radiotherapy or surgery for spinal cord compression is required.

排除标准
- •Patients with HER2-negative disease.
- •Subjects who, in the opinion of the investigator, are unable to comply with the protocol requirements or who have any comorbidity or condition that may hinder study follow-up, response evaluation, or the informed consent process, including inability to read and understand the local language of the study site sufficiently to interact effectively with study materials and tools (including digital applications).
- •Note: Other languages for app-based questionnaires may be provided upon patient request and based on availability of such questionnaires and tools.
- •History of other primary malignancy unless treated with curative intent with no evidence of active disease within 3 years before the first dose of study treatment and of low potential risk for recurrence. Exceptions include: basal cell carcinoma of the skin and squamous cell carcinoma of the skin that has undergone potentially curative therapy, adequately resected non-melanoma skin cancer, in situ cancer of the cervix, curatively treated ductal carcinoma in situ (DCIS), contralateral breast cancer, Stage 1, grade 1 endometrial carcinoma or other solid malignant tumors with an expected curative outcome after Medical Monitor approval.
- •Persistent toxicities that the investigator deems related to previous anti-cancer therapy (excluding alopecia), not yet resolved to grade ≤ 1 or baseline. Participants with irreversible toxicity that is not reasonably expected to be exacerbated by study treatment may be included (e.g., hearing loss). Participants with stable Grade 2 toxicities (defined as no worsening to >Grade 2 for at least 3 months prior to enrollment and managed with standard of care treatment) may be eligible per the discretion of the investigator (e.g., Grade 2 chemotherapy-induced neuropathy).

- •Participants with a known history of human immunodeficiency virus (HIV) are eligible, if viral load is undetectable for ≥ 6 months prior to enrollment, and subjects are receiving effective anti-retroviral HIV therapy, if indicated. HIV testing is not required for subjects without a known history of HIV, unless mandated by a local health authority.
- •For patients with a known history of HBV infection, a hepatitis B core antibody test should be conducted at screening. If positive, hepatitis B DNA testing will be performed and if active HBV infection is ruled out, the patient may be eligible.
- •Patients who are HCV antibody positive with polymerase chain reaction negative for HCV RNA may be eligible
- •Other concurrent medical or psychiatric conditions that, in the investigator's opinion, may be likely to confound study interpretation or prevent completion of study procedures and follow-up examinations.
