Inclusion criteria

  • {"criterion_text":"- Pathologically documented breast cancer that: (a) Is unresectable/advanced or metastatic, and (b) Has confirmed HER2-positive status as determined according to ASCO/CAP guidelines (Wolff et al, 2018) evaluated at a local laboratory"}
  • {"criterion_text":"- Participant must have either: (a) No evidence of BM, or (b) Untreated BM on screening contrast brain MRI / CT scan (i)not needing immediate local therapy, or (ii)For participants with untreated CNS lesions: - if lesion ≤ 2 cm, no discussion with study physician is required prior to enrollment- if lesion is > 2.0 cm, discussion with and approval from the study physician is required prior to enrollment, or (c) Previously treated stable or progressing BM (i) Previously treated BM with local therapy may either be radiographically stable for ≥ 4 weeks since completion of treatment or may have progressed since prior local CNS therapy, provided that there is no clinical indication for immediate re-treatment with local therapy (ii) Patients treated with CNS local therapy for newly identified lesions found on contrast brain MRI/CT scan performed during screening for this study who also have other sites of disease assessable by RECIST 1.1"}
  • {"criterion_text":"- Participants with BMs must be neurologically stable and: (a) Be receiving the equivalent of dexamethasone ≤ 3 mg/day if treatment is required (b) If receiving an anticonvulsant regimen, the regimen must have been stable for ≥ 14 days before first day of dosing (c) Relevant records of any CNS treatment must be available to allow for classification of TLs and NTLs"}
  • {"criterion_text":"- Previous breast cancer treatment: (a) Radiologic or objective evidence of disease progression on or after HER2 targeted therapies. Note: Disease progression within 6 months after adjuvant treatment with HER2 targeted therapies is also acceptable. (b) No more than 2 lines/regimens of therapy in the metastatic setting. Note: A line/regimen of treatment should be counted based on a progression event."}

Exclusion criteria

  • {"criterion_text":"- Known or suspected LMD"}
  • {"criterion_text":"- Prior exposure to tucatinib treatment"}
  • {"criterion_text":"- Based on screening contrast brain MRI/ CT scan, participants must not have any of the following: (a) Any untreated brain lesions > 2.0 cm in size (b) Ongoing use of systemic corticosteroids for control of symptoms of BMs at a total daily dose of > 3 mg of dexamethasone (or equivalent). (c) Any brain lesion thought to require immediate local therapy, (d) Have poorly controlled (> 1/week) generalized or complex partial seizures, or manifest neurologic progression due to BMs notwithstanding CNS-directed therapy"}
  • {"criterion_text":"- Has spinal cord compression"}

Endpoints

Primary endpoints

  • {"endpoint_text":"- •Participants without BM at baseline (Cohort 1): ORR by RECIST 1.1 per ICR • Participants with BM at baseline (Cohort 2): PFS by RECIST 1.1 per ICR","definition_or_measurement_approach":"For Cohort 1: Objective Response Rate (ORR) assessed by RECIST 1.1 as adjudicated by Independent Central Review (ICR). For Cohort 2: Progression-Free Survival (PFS) assessed by RECIST 1.1 as adjudicated by ICR."}

Secondary endpoints

  • {"endpoint_text":"- • Both cohorts: - OS; - DoR (RECIST ICR); - Time to progression (RECIST ICR); - DoT on subsequent therapy lines; - PFS2. • Cohort 1 only: - Incidence of new symptomatic CNS metastasis during treatment. • In patients with isolated CNS progression, receive local therapy, and continue on protocol therapy: - Time to next progression (CNS or extracranial) or death; - Site (CNS vs extracranial vs both) of next progression.","definition_or_measurement_approach":"OS = Overall Survival; DoR, Time to progression measured by RECIST 1.1 as adjudicated by ICR; DoT = Duration of Treatment on subsequent lines; PFS2 = second progression-free survival. Incidence of symptomatic CNS metastasis captured clinically during treatment; time to next progression and site of next progression recorded per protocol assessments."}
  • {"endpoint_text":"- Participants with BM at baseline (Cohort 2): - ORR by RECIST 1.1 per ICR; - CNS PFS by CNS RECIST 1.1 per ICR; - Time to new CNS lesions; - CNS ORR by CNS RECIST 1.1 per ICR; - CNS DoR by CNS RECIST 1.1 per ICR","definition_or_measurement_approach":"ORR and CNS-specific endpoints assessed by CNS RECIST 1.1 and RECIST 1.1 as adjudicated by ICR; time to new CNS lesions measured from baseline to first occurrence of new CNS lesions."}
  • {"endpoint_text":"- Changes in symptoms, functioning, and HRQoL as measured by • All patients: EORTC QLQ-C30, NANO scale, cognitive tests. • BM patients: MDASI brain tumor-specific items. • ILD/pneumonitis patients: SGRQ-I","definition_or_measurement_approach":"Patient-reported outcomes and scales: EORTC QLQ-C30, NANO neurological assessment, cognitive tests, MDASI brain tumor items for BM patients, and SGRQ-I for ILD/pneumonitis; changes measured relative to baseline per instrument scoring rules."}
  • {"endpoint_text":"- Safety and tolerability will be evaluated in terms of AEs, vital signs, clinical laboratory results, and ECGs, rate of investigator-assessed ILD/pneumonitis, and rate of AEs among patients with baseline BM who are treated with concurrent high-dose steroid (total daily dose > 2 mg dexamethasone or equivalent)","definition_or_measurement_approach":"Safety assessed by adverse events (AEs), vital signs, labs, ECGs; ILD/pneumonitis rates assessed by investigator; special safety subgroup analysis for patients on high-dose steroids (>2 mg dexamethasone or equivalent)."}
